Moisture in the interiorof the tool may cause a short circuit and chemicalreactions resulting in burns to the skin or fire.d) Under abusive conditions, liquid may leak from thebattery. Avoid contact. If contact accidentally oc-curs, flush with water. In the event of the liquidcoming into contact with the eyes, rinse the eyeswith plenty of water and consult a doctor. Liquidejected from the battery may cause irritation or burns.e) Use only batteries of the type approved for usewith the applicable tool. Use of other batteries oruse of the batteries for purposes for which they arenot intended presents a risk of fire and explosion.f) Observe the special guidelines applicable to thetransport, storage and use of Li-ion batteries.g) When not in use, keep the battery and the chargeraway from paper clips, coins, keys, nails, screwsor other small metal objects that could cause ashort circuit at the battery terminals or the char-ging contacts. A short circuit at the battery terminalsor charging contacts could result in personal injury(burns) or fire.h) Avoid short circuiting the battery terminals. Checkthat the battery terminals and the terminals in thedevice are free from foreign objects before insertingthe battery in the device. Short circuiting the bat-tery terminals presents a risk of fire, explosion andchemical burns.i) Do not charge or continue to use damaged bat-teries (e.g. batteries with cracks, broken parts,bent or pushed-in and/or pulled-out contacts).j) Use only the PUA 81 AC adapter, PUA 82 motorvehicle power adapter or other chargers recom-mended by the manufacturer to power the tool orcharge the battery. Failure to observe these pointsmay result in damage to the tool. A charger that issuitable for a certain type of battery may present arisk of fire when used with other types of battery.en3
2.3 Proper organization of the work areaa) Secure the area in which you are working andtake care to avoid directing the beam towardsother persons or towards yourself when settingup the tool.b) Avoid unfavorable body positions when workingfrom ladders. Make sure you work from a safestance and stay in balance at all times.c) Readings taken in the vicinity of reflective objects orsurfaces, through panes of glass or similar materialsmay produce incorrect results.d) Ensure that the tool is set up on a steady, levelsurface (not subject to vibration).e) Use the tool only within its specified limits.f) Make sure that your PR 300-HV2S is responding onlyto your PRA 300 and not to any other PRA 300 thatmay be in use on the jobsite.g) When working in “charging during operation”mode, attach the AC adapter in a secure posi-tion, e.g. on a tripod.h) Use of products for applications different from thoseintended could result in hazardous situations. Usethe product and its accessories etc. in accord-ance with these instructions and in the mannerintended for the particular type of product. Takethe working conditions and the work to be per-formed into account.i) Use of the telescopic staff in the vicinity of over-head high voltage cables is not permissible.2.3.1 Electromagnetic compatibilityAlthough the tool complies with the strict requirementsof the applicable directives, Hilti cannot entirely rule outthe possibility of the tool being subject to interferencecaused by powerful electromagnetic radiation, leadingto incorrect operation. Check the accuracy of the toolby taking measurements by other means when workingunder such conditions or if you are unsure. Likewise, Hilticannot rule out the possibility of interference with otherdevices (e.g. aircraft navigation equipment).2.3.2 Laser classification for Laser Class 2productsAccording to the version purchased, the tool complieswith Laser Class 2 as per IEC60825-1:2007 / EN60825-1:2007. This tool may be used without need for furtherprotective measures. Nevertheless, as with the sun, oneshould not look directly into sources of bright light. In theevent of direct eye contact with the laser beam, closeyour eyes and move your head out of the path of the laserbeam. Do not direct the laser beam toward persons.3 Description3.1 Use of the product as directedThe Hilti PR 300-HV2S is a rotating laser tool with a visible rotating laser beam and a reference beam set at 90° to themain beam. The rotating laser can be used vertically, horizontally and for inclinations in one or two planes.The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles. Examples ofits uses are: transferring datums and height marks, determining right angles for walls, vertical alignment on referencepoints and setting out slopes.The tool is designed for professional use and may be operated, serviced and maintained only by trained, authorizedpersonnel. This personnel must be informed of any special hazards that may be encountered. The tool and its ancillaryequipment may present hazards when used incorrectly by untrained personnel or when used not as directed.Hilti supplies various accessories which allow the tool to be used with maximum efficiency.To avoid the risk of injury, use only genuine Hilti accessories and insert tools.3.2 FeaturesThe tool makes it possible for a single person to level or align in any plane quickly and with great accuracy.Leveling takes place automatically after the tool is switched on. The laser beam is activated after the tool has leveleditself.LEDs indicate the current operating status.The tool is powered by a rechargeable Li‑ion battery which can be charged while the tool is in operation.3.3 Combined use of the PRA 300 remote control / laser receiverThe PRA 300 is a combined remote control unit and laser receiver. It can be used to control the PR 300-HV2S rotatinglaser over great distances. The PRA 300 also serves as a laser receiver and can thus be used to detect and indicatethe laser beam at great distance.3.4 Digital distance measurement displayThe laser receiver displays digitally the distance between the laser plane and the marking notch. This allows the user todetermine the exact position of the receiver relative to the laser plane, with millimeter accuracy, in a single operation.en4
3.5 Automatic alignment and surveillanceUsing the PR 300-HV2S and the PRA 300, a single person can align the laser plane automatically with a certain pointwith great accuracy. The tool detects the applicable alignment (horizontal, vertical or inclined) automatically and usesthe automatic alignment function accordingly (horizontal with the PRA 90 plus inclination) or automatic alignment withsubsequent monitoring of the plane (vertical). With the aid of the PRA 300, the surveillance function checks alignmentof the laser plane at regular intervals in order to avoid possible deviations due to temperature fluctuations, wind orsimilar. The surveillance function can be deactivated.3.6 Digital inclination displayThe digital inclination display is capable of indicating an inclination of up to 25% when the PR 300-HV2S is operatingin inclined mode. This makes it possible to set out and check slopes without having to make any calculations. Manualelectronic inclination alignment allows optimum inclination accuracy.3.7 Shock warningThe shock warning function is activated two minutes after the tool has leveled itself after switching on. If a key ispressed within these two minutes, the two-minute delay begins again. The tool switches to warning mode if it isbrought out of level while in operation (due to vibration or an impact); all LEDs begin to blink and the laser switchesoff (the head stops rotating).3.8 Automatic cut-outThe laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range (±16° X-axis, ±10°Y-axis) or if movement is blocked mechanically.The tool can be set up on a tripod with a 5/8" thread or stood directly on some other steady surface (free of vibration).When automatic leveling is activated for one or both axes, the built-in servo system ensures that the specified accuracyis maintained. The tool switches itself off when automatic leveling cannot be achieved (tool set up outside its levelingrange or physical impediment of the mechanism) or when knocked off level (see “Shock warning” section).NOTEIf the correct level cannot be achieved, the laser switches itself off and all LEDs blink.3.9 Items supplied1 PR 300-HV2S rotating laser1 PRA 300 laser receiver / remote control unit1 PRA 83 laser receiver holder1 Operating instructions1 PRA 84 Li-Ion battery1 PUA 81 AC adapter2 Batteries (size AA cells)2 Manufacturer’s certificates1 Hilti toolboxNOTEAccessories are available from your Hilti Center or can be ordered online at www.hilti.com.3.10 Operating status indicatorsThe tool is equipped with the following operating status indicators: Auto-leveling LED, battery charge status LED,shock warning function deactivation LED, inclined plane mode LED, surveillance mode LED and electronic inclinationalignment LED.en5

Set up the tool in a suitable position for the application, e.g. on a tripod. Alternatively, the rotating laser may bemounted on a wall bracket. The angle of inclination of the surface on which it stands should not exceed ± 5°.2. Press the on/off button .The “auto leveling” LED blinks green and the leveling status is shown in the display on the laser receiver.The laser switches on, the beam begins to rotate and the “auto leveling” LED lights as soon as the tool hasleveled itself.en14
6.6.2 Alignment using the PRA 90 automatic tripodNOTEThis function is available only with the PRA 90 automatic tripod.When used for the first time, the PRA 300 laser receiver must be paired with the tripod (see 6.9.2).With the optional PRA 90 automatic tripod you can set the height of the laser plane to the desired level manually orautomatically.1. Mount the tool on the PRA 90 automatic tripod.2. Switch on the rotating laser, the automatic tripod and the laser receiver. Set the height of the laser plane manually(see 6.6.2.1) or automatically (see 6.6.2.2).6.6.2.1 Manual alignment 6 Press the keys on the laser receiver or the arrow keys on the PRA 90 to shift the horizontal plane up or down(parallel).6.6.2.2 Automatic alignment 6 1. Hold the laser receiver at the desired height with the detection area facing the PRA 90 control panel. Hold thelaser receiver still while alignment is taking place and take care to ensure that the line of sight between the laserreceiver and the tool is not obstructed.2. Press the “Automatic alignment” key on the laser receiver twice in quick succession (double-click). Double-clickthe key again to complete the procedure.The laser plane alignment process is then started, i.e. the tripod elevates or lowers itself to the required height. Aconstant signal tone is emitted while this is taking place. As soon as the laser beam strikes the detection area ofthe laser receiver, the beam moves to the position of the marking notch (reference plane).After the position has been reached and the rotating laser has leveled itself, a signal tone with a duration of 5seconds indicates that the process is complete. The “Automatic alignment” symbol is then no longer shown.3. Check the height settings in the display.4. Remove the laser receiver.NOTE If the automatic alignment process was not successful, short signal tones are emitted and the “Automaticalignment” symbol disappears.NOTE A warning is also displayed on the laser receiver indicating that the receiver is outside the possiblereceiving area.6.7 Working in the vertical plane1. When working in the vertical plane, mount the tool on a suitable tripod, facade adapter, batter board adapter orwall bracket, with the control panel facing upwards. Alternatively, the tool can be stood on the rubber feet on therear grips.NOTE The best wireless connection with the PRA 300 is provided by the side of the tool to the right of the controlpanel.NOTE In order to ensure that the tool’s specified accuracy can be maintained, make sure that it is set up on alevel surface or mounted sufficiently level on the tripod or other accessory.2. Use the visual sighting method (front and rear sights) to align the rotating laser in the desired direction.en15
3. Press the on/off button .After the tool has leveled itself automatically, it projects a stationary laser beam vertically downwards. Thisprojected point is a reference point (not a plumb point) and can be used to help position the tool.4. Align the tool so that the projected laser point coincides exactly with a reference point (e.g. nail on a batter board).5. Now line up the laser plane with the second reference point manually (see 6.7.1) or automatically (see 6.7.2).The laser begins to rotate automatically as soon as you begin the alignment operation.6.7.1 Manual alignment 6 1. Press the arrow keys on the laser receiver in order to align the vertical plane manually.6.7.2 Automatic alignment and surveillance 6 1. Mount or hold the laser receiver with the marking notch at the desired alignment point and facing the rotatinglaser.2. Double-click the “Automatic alignment” key . Double-click the key again to complete the procedure.The laser plane alignment procedure then begins. A constant signal tone is emitted while this is taking place.The direction of the search can be changed by pressing the “Automatic alignment” key once.As soon as the laser beam strikes the detection area of the laser receiver, the beam moves to the position of themarking notch (reference plane).Once the position is reached (i.e. the marking notch is found), a signal tone with a duration of 5 seconds indicatesthat the process is complete.The laser receiver switches automatically to surveillance mode and checks at regular intervals whether the laserplane has shifted. If it is found to have shifted, the laser plane will be readjusted to the original marking notch asfar as possible. If the marking plane is outside the leveling range of ±5°, direct line of sight between the rotatinglaser and the laser receiver is obstructed for a long period or the alignment process is not completed successfullywithin a time of 2 minutes, then short signal tones are emitted, the laser stops rotating and the “Automaticalignment” symbol disappears. This indicates cancellation of the automatic alignment process.3. After the automatic alignment process is completed and, instead of leaving the receiver in position, you wish touse the device again as a receiver, you can leave surveillance mode again by pressing the “Automatic alignment”key twice in quick succession (double click).6.8 Working with slopesNOTEIf the tool measures a change in temperature of more than 10 degrees, laser rotation stops for about 40 seconds.During this time the tool corrects all errors that may have been caused by the temperature change. After this automaticcorrection the tool resets the laser plane to the previous inclination and the laser again begins to rotate.Tool is levelLeveling switched off in order to work with the slope adapteren16
Last previously used inclination valueX-axisY-axisThe inclination can be set manually, automatically, or by using the PRA 79 slope adapter.6.8.1 Setting up1. Mount the rotating laser on a tripod.2. Position the rotating laser at the first reference point either at the upper edge or lower edge of the inclined plane.3. Position yourself behind the tool, facing the control panel.4. With the aid of the visual sighting method (using the front and rear sights on the head of the tool), aim the toolroughly at the second reference point, keeping it parallel to the inclined plane.5. Switch the laser receiver on .6. Switch the tool on and then press the “Inclined plane mode” key .The “Inclined plane mode” LED then lights.The laser beam switches on as soon as the tool has leveled itself. The control panel of the PRA 300 then offersthe following ways of adjusting the inclination:– Digital adjustment of the X or Y values .– Switch off the leveling control (to allow use with the PRA 79 slope adapter)– Recall the last previously used value .For more precise adjustment, first set the inclination and then carry out manual electronic inclination alignment(see 6.8.2.1). Inclination can be set and displayed on the PRA 300 in %, ⁰⁄₀₀ or in ° (see 6.5.4).6.8.2 Setting the inclination manually (digital entry) Inclination values of up to 20% can be entered with the laser receiver / remote control unit. The display on the laserreceiver shows the angle of inclination. If a slope adapter or an already inclined tripod is also used, inclinations of upto 25% can be achieved.You can set the X and Y inclinations at the same time or for just one of the two axes.1. Use the arrow keys or to select soft key X and then confirm your choice by pressing .2. Then use the arrow keys or to select the digit or character that you wish to set and activate it by pressing.3. Enter the desired value by way of the arrow keys or and confirm each digit by pressing – only then cana new digit be selected.4. After entering the desired value, confirm your input by pressing .5. Use the arrow keys to navigate to the OK key and press .6. You can now enter the Y-value or go straight to “Confirm” . The laser beam will be adjusted only when youconfirm this step.NOTE Alternatively, before confirming, you can press the “Back” key and return to the main menu, therebydeleting the entries you have made.6.8.2.1 Optional manual electronic inclination alignmentAfter aligning the rotating laser approximately and setting the inclination as described above, alignment of thePR 300-HV2S can be optimized through use of Hilti’s patented manual electronic alignment system.1. Position the PRA 300 centrally opposite the PR 300-HV2S at the end of the inclined plane. It can be held still byhand or fixed in place with the aid of the PRA 83.NOTE The detection area must be aligned with the second reference point.en17
2. Activate manual electronic inclination alignment on the PR 300-HV2S by pressing the “Electronic inclinationalignment” key.If the arrows for electronic inclination alignment blink, the PRA 300 is receiving no laser beam from thePR 300-HV2S.3. If the left arrow lights, turn the PR 300-HV2S clockwise.4. If the right arrow lights, turn the PR 300-HV2S counter-clockwise.When both arrows light, the PRA 300 is correctly aligned.After successful alignment (both arrows light constantly for 10 seconds), the function ends automatically.5. Then secure the rotating laser on the tripod so that it cannot be inadvertently moved out of position.6. You can also end electronic inclination alignment by pressing the “End manual electronic inclination alignment”key.NOTE There may be divergence between the results obtained by approximate alignment with the aid of thevisual sighting method (using the front and rear sights) and fine alignment with the aid of manual electronicinclination alignment. As the manual electronic method is more accurate than the visual method, we recommendthat electronic inclination alignment is always used as the reference.6.8.3 Measuring a given inclination automatically With this function you can create an inclined laser plane between 2 points automatically and determine the angle ofinclination between these points.1. Set up the rotating laser at the top edge of the inclined plane as described in 6.8.1.2. Mount the laser receiver with the PRA 83 receiver holder, for example, on the PUA 53 telescopic staff.3. Position the receiver immediately in front of the rotating laser, bring it into alignment with the laser plane at thecorrect height, and then secure it at the second reference point on the telescopic staff.4. Position the receiver on the telescopic staff at the lower edge of the inclined plane, click the “Automatic alignment”key and confirm this by pressing .NOTE Double-click the AUTO key again to complete the alignment procedure.The laser plane alignment procedure then begins. A constant signal tone is emitted while this is taking place.5. The direction of the search can be changed by pressing the “Automatic alignment” key once.As soon as the laser beam strikes the detection area of the laser receiver, the beam is fixed at the position of themarking notch (reference plane). Once the position is reached (i.e. the marking notch is found), a signal tone witha duration of five seconds indicates that the process is complete.The “Automatic alignment” symbol is no longer shown in the display on the laser receiver and the receiverswitches automatically to normal operating mode.The new inclination is shown in the display on the laser receiver.6. Read the inclination between the two points (positions of the rotating laser and the laser receiver) from the displayof the laser receiver.6.8.4 Setting the inclination with the aid of the PRA 79 slope adapterNOTECheck that the slope adapter is fitted correctly between the tripod and the tool (please refer to the operating instructionsfor the PRA 79).1. Set up the PRA 79 slope adapter in a suitable position for the application, e.g. on a tripod.2. Position the tripod either at the upper edge or lower edge of the inclined plane.3. Mount the rotating laser on the slope adapter and, with the aid of the sights on the head of the PR 300-HV2S,adjust the tool and slope adapter so that they are parallel to the inclined plane. The control panel of thePR 300-HV2S should face away from the direction of inclination.4. Make sure that the slope adapter is in the zero position (0°).5. Switch the tool on (see 6.3).6. Press the “Inclined plane mode” key .The “Inclined plane mode” LED then lights on the control panel of the rotating laser.The tool then begins automatic self-leveling. The laser switches on and begins to rotate as soon as this iscomplete.7. On the receiver, now press to deactivate the leveling function.8. Set the slope adapter to the desired angle of inclination.NOTE When the angle of inclination is set manually, the PR 300-HV2S levels the laser plane once and thensubsequently fixes it. Vibration, changes in temperature or other influences that may occur during the course ofthe day may affect the position of the laser plane.NOTE In order to enter digital manual settings for X/Y, you must first set the tool to the standard operating mode.To do this, the system must be restarted.en18
6.9 Recalling the last previous valueIf you switch the tool off to reposition it, the last previous inclination value saved in the receiver can be recalled.1. Switch the tool on again and activate inclined plane mode .The first item in the menu is the last previous value.2. Press to select the value.3. Check that the X and Y-values are, in fact, correct.4. Confirm the values by pressing .The rotating laser then resets itself to the previous inclination.6.10 Resetting the X/Y value Use the “Reset to 0” soft key to quickly reset the X and Y-values to 0.6.11 Returning to standard modeTo return to standard operating mode, switch the tool off and then switch it back on again.7 Care and maintenance7.1 Cleaning and drying1. Blow dust off exit windows.2. Do not touch the glass with the fingers.3. Use only a clean, soft cloth for cleaning. If necessary,moisten the cloth slightly with pure alcohol or a littlewater.NOTE Abrasive cleaning materials may scratch theglass and impair the accuracy of the laser tool.NOTE Do not use any other liquids as these maydamage the plastic components.4. Dry the equipment, observing the maximum tem-peratures given in the technical data.NOTE Especially in summer and winter, take carethat the given maximum and minimum temperaturesare not exceeded, e.g. when the equipment is storedin a motor vehicle.7.2 Care of Li‑ion batteriesNOTEWith Li-ion batteries, a conditioning charge (as is requiredwith NiCd or NiMH batteries) is not necessary.NOTEInterruption of the charging procedure has no negativeeffect on battery life.NOTECharging can be started at any time with no negative ef-fect on battery life. There is no memory effect (in contrastto NiCd or NiMH batteries).NOTEFor best results, batteries should be stored fully chargedin a cool, dry place. Storing the battery in places subjectto high ambient temperatures (e.g. at a window) has anadverse effect on battery life and increases the rate ofself-discharge.NOTEBatteries lose capacity due to aging and overstressing.They can then no longer be fully charged. You maycontinue to work with a battery that shows signs ofaging, but the battery should be replaced in good time.1. Avoid ingress of moisture.2. Charge the battery fully before using it for the firsttime.3. Charge the battery as soon as performance dropsnoticeably.NOTE Recharging in good time will increase theservice life of the battery.NOTE If use of the battery continues, further dis-charge will be stopped automatically before thebattery cells suffer damage, i.e. the tool switchesitself off.4. Charge the batteries using only the Hilti chargersapproved for use with Li-ion batteries.7.3 Storage1. Remove the tool from its case if it has become wet.Dry and clean the tool, its transport container andaccessories (while observing the permissible tem-perature range). Repack the equipment only once itis completely dry.2. Check the accuracy of the equipment before it isused after a long period of storage or transportation.3. Remove rechargeable and non-rechargeable batter-ies from the tool or the laser receiver before storingthe units for long periods. The tool or laser re-ceiver may suffer damage caused by leakage fromrechargeable or non-rechargeable batteries.7.4 TransportUse the Hilti toolbox or packaging of equivalent qualityfor transporting or shipping your equipment.CAUTIONAlways remove the batteries before shipping the tool.7.5 Hilti Measuring Systems ServiceHilti Measuring Systems Service checks the tool and, ifdeviations from the specified accuracy are found, recal-en19
ibrates the tool and checks it again to ensure conformitywith specifications. The service certificate provides writ-ten confirmation of conformity with specifications at thetime of the test.The following is recommended:1. The tool should be checked at suitable intervals,depending on the frequency of normal use.2. The tool should be checked at least once a year bya Hilti Measuring Systems Service Center.3. The tool should be checked by a Hilti MeasuringSystems Service Center if it has been abused in anyway.4. The tool should be checked by a Hilti MeasuringSystems Service Center before being used for par-ticularly important work.Having the tool checked by a Hilti Measuring Sys-tems Service Center does not relieve the user ofhis/her obligation to check the tool before and dur-ing use.7.6 Checking accuracyNOTEIn order to ensure compliance with the technical spe-cifications, the tool should be checked regularly (at leastbefore each major / relevant job).NOTEAfter falling and suffering an impact it can be assumedthat the tool will continue to operate faultlessly, withthe accuracy it achieved prior to the impact, when thefollowing conditions are met:The height of the fall did not exceed the height given inthe technical data.The tool suffered no obvious mechanical damage fromthe impact (e.g. breakage of the pentaprism).The tool projects a rotating laser beam when in operation.The tool operated faultlessly before the impact.7.6.1 Checking the main and transverse horizontalaxes 1. Set up the tripod approx. 20 m (66 ft) from a walland adjust the tripod head horizontally with a spiritlevel.2. Mount the tool on the tripod and use the visualsighting method (front and rear sights) to aim thetool at the wall.3. Use the receiver to catch the laser beam and marka point (point 1) on the wall.4. Pivot the tool clockwise through 90° about its ownaxis. In doing so, ensure that the height of the tooldoes not change.5. Use the laser receiver to catch the laser beam andmark a second point (point 2) on the wall.6. Repeat steps 4 and 5 twice and mark points 3 and4 on the wall with the aid of the laser receiver.When this is done carefully, the vertical distancebetween the two marked points, i.e. points 1 and 3(main axis) or points 2 and 4 (transverse axis) shouldbe < 2 mm (0.08 in) at 20 m (66 ft) in each case. Ifthe deviation is greater than this, the tool should bereturned to a Hilti Service Center for calibration.7.6.2 Checking the vertical axis  1. Place the tool in the vertical position on a floor,which is as flat as possible, approx. 10 m (33 ft)from a wall.2. Adjust the position of the tool so that the grips areparallel to the wall.3. Switch the tool on and mark the reference point (R)on the floor.4. With the aid of the receiver, mark point (A) low onthe wall.5. With the aid of the receiver, mark point (B) at aheight of approx. 10 m (33 ft).6. Pivot the tool through 180° and realign it with thereference point (R) on the floor and with point (A) atthe base of the wall.7. With the aid of the receiver, mark point (C) at aheight of approx. 10 m (33 ft).8. Check the distance between points (B) and (C).When the procedure has been carried out carefully,the horizontal distance between the two points (B)and (C) marked at a height of ten meters should beless than 1 mm (0.04 in) at 10 m (33 ft).NOTE If the deviation is greater: Please return thetool to Hilti Service for calibration.8 TroubleshootingEvery item shown in the display is accompanied by either the “Information” or the “Warning” symbol (see section“Overview of general symbols”).Message displayed Fault Possible cause RemedyInclination angle too high.The tool cannot achievethe given inclination.Inclination angle too high Reposition the tool sothat the inclination valueyou have entered can beachieved.en20
