The PR 30-HVS can be used for alignment in the vertical, horizontalandinclinedplanes.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.Observe the information printed in the operating instructions concerning operation, care and maintenance.Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire orexplosion.Modification of the tool is not permissible.en2
2.2 FeaturesThetoolmakesitpossibleforasinglepersontoleveloraligninanyplanequickly and with great accuracy.The tool levels itself automatically after switching on. The laser beam is emitted only when the specified accuracy hasbeen achieved.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.2.3 PRA 30 combined remote control and laser receiverThe PRA 30 is a combined remote control unit and laser receiver. It can be used to control the PR 30-HVS rotatinglaser over great distances. The PRA 30 also serves as a laser receiver and can thus be used to detect and indicate thelaser beam at great distance.2.4 Digital distance measurement displayThe PRA 30 displays digitally the distance between the laser plane and the marking notch on the PRA 30. This allowsthe user to determine the exact position of the receiver relative to the laser plane, with millimeter accuracy, in a singleoperation.2.5 Automatic alignment and surveillanceUsing the PR 30-HVS and the PRA 30, a single person can align the laser plane automatically with a certain pointwith great accuracy. The tool detects the applicable alignment (horizontal, inclined or vertical) 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 30, 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.2.6 Digital inclination display with patented electronic inclination alignmentThe digital inclination display is capable of indicating an inclination of up to 21.3% when the PR 30-HVS is operating ininclined mode. This makes it possible to set out and check slopes without having to make any calculations. Electronicinclination alignment allows optimum inclination accuracy.2.7 Shock warningThe shock warning function is activated one minute after the tool has leveled itself after switching on. The waiting timeof one minute begins again if a button is pressed within this first minute. 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).2.8 Automatic cut-outThe laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range (±5°) or if movementis 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.2.9 Items supplied1 PR 30-HVS rotating laser1 PRA 30 remote control unit / laser receiver1 PRA 80/PRA 83 receiver holder1 Operating instructions2 Manufacturer’s certificates1 PRA 84 Li‑ion battery1PUA81ACadapteren3

To save the settings, switch the PRA 30 off.NOTE Each setting that has been made becomeseffective the next time the tool is switched on.7.3.8 Double-clickWhen operating the tool, the “automatic alignment”and “surveillance” commands must be confirmed witha double-click in order to avoid incorrect operation.7.4 Deactivating the shock warning system1. Switch the tool on (see 7.2).2. Press the “Deactivate shock warning system” but-ton.The shock warning system LED lights constantly,indicating that the function has been deactivated.3. To return to standard operating mode, switch thetool off and then switch it back on again.7.5 Working in the horizontal plane7.5.1 Setting up1. Set up the tool in a suitable position for the applica-tion,e.g.onatripod.Alternatively,therotatinglasermay be mounted on a wall bracket. The angle ofinclination of the surface on which it stands shouldnot exceed ± 5°.2. Press the on/off button.The auto-leveling LED blinks green.The laser switches on, the beam begins to rotateand the “auto leveling” LED lights as soon as thetool has leveled itself.7.5.2 Alignment using the PRA 90 automatic tripodNOTEThis function is available only with the PRA 90 automatictripod.When used for the first time, the PRA 30 laser receivermust be paired with the tripod (see 6.9.2).With the optional PRA 90 automatic tripod you can setthe height of the laser plane to the desired level manuallyor automatically.1. Mount the tool on the PRA 90 automatic tripod.2. Switch on the rotating laser, the automatic tripodand the laser receiver. Set the height of the laserplane manually (see 7.5.3) or automatically (see7.5.4).7.5.3 Manual alignment Press the +/- buttons on the PRA 30 or the arrow buttonson the PRA 90 to shift the horizontal plane up or down(parallel).7.5.4 Automatic alignment 21. Hold the PRA 30 laser receiver at the desired heightwith the receiving window facing the PRA 90 controlpanel. Hold the PRA 30 still while alignment is takingplace and make sure that the line of sight betweenthe PRA 30 and PR 30-HVS is unobstructed.en11
2. Press the “automatic alignment” button on the laserreceiver twice in quick succession (double-click).Double-click the button again to complete align-ment.This double-click starts the process of bringing thelaser plane into alignment, i.e. the tripod elevates orlowers itself to the required height. A constant signaltone is emitted while this is taking place. As soonas the laser beam strikes the receiving window ofthe PRA 30, the beam moves to the position of themarking notch (reference plane).After the position has been reached and the PR30-HVS rotating laser has leveled itself, an audiblesignal with a duration of 5 seconds indicates thatthe process is complete. In addition, the automaticalignment icon is no longer shown.3. Check the height settings on the display.4. Remove the PRA 30.NOTE If the automatic alignment process was notsuccessful, short signal tones are emitted and theautomatic alignment symbol goes out.7.6 Working in the vertical plane1. When working in the vertical plane, mount the toolon a suitable tripod, facade adapter, batter boardadapter or wall bracket, with the control panel facingupwards. Alternatively, the tool can be stood on therubber feet on the rear grips.NOTE The best wireless connection with the PRA 30is provided by the side of the tool to the right of thecontrol panel.NOTE In order to ensure that the tool’s specifiedaccuracy can be maintained, make sure that it is setup on a level surface or mounted sufficiently levelon the tripod or other accessory.2. Use the visual sighting aids to adjust the tool so thatitsverticalaxisisalignedintherequireddirection.3. Press the on/off button.After the tool has leveled itself automatically, itprojects a stationary laser beam vertically down-wards. This projected point is a reference point (nota plumb point) and can be used to help position thetool.4. Align the tool so that the projected laser point co-incides exactly with a reference point (e.g. nail on abatter board).5. Now line up the laser plane with the second refer-ence point manually (see 7.6.1) or automatically (see7.6.2).The laser begins to rotate automatically as soon asyou begin the alignment operation.7.6.1 Manual alignment 31. Press the direction buttons (left / right) on the PRA 30to bring the vertical plane into alignment.7.6.2 Automatic alignment and surveillance 1. Hold the PRA 30 with the marking notch at thedesired alignment point and facing the PR 30-HVS.2. Double-click the “automatic alignment” button.Double-click the button again to complete theprocedure.This double-click starts the process of bringing thelaser plane into alignment. A constant signal tone isemitted while this is taking place.The direction of the search can be changed bypressing the “automatic alignment” button.As soon as the laser beam strikes the receivingwindow of the PRA 30, the beam moves to theposition of the marking notch (reference plane).Once the position is reached (i.e. the marking notchis found), an audible signal with a duration of 5seconds indicates that the process is complete.The laser receiver switches automatically to surveil-lance mode and checks at regular intervals whetherthe laser plane has shifted. If it is found to haveshifted, the laser plane will be readjusted to theoriginal marking plane as far as possible. If themarking plane is outside the leveling range of ±5°,direct line of sight between the rotating laser andthe laser receiver is obstructed for a long period orthe alignment process is not completed success-fullywithinatimeof2minutes,thenshortsignaltones are emitted, the laser stops rotating and “au-tomatic alignment” symbol goes out. This indicatescancellation of the automatic alignment process.3. Double-click the “automatic alignment” button toleave surveillance mode.7.7 Working with slopes7.7.1 Setting upNOTEThe slope can be set manually, automatically, or by usingthePRA79slopeadapter.1. Set up the tool in a suitable position for the applica-tion, e.g. on a tripod.2. Position the rotating laser either at the upper edgeor lower edge of the inclined plane.3. Position yourself behind the tool, facing the controlpanel.4. With the aid of the target notch on the head ofthe tool, bring the tool roughly into alignment withthe inclined plane (parallel to the plane). For moreprecise adjustment, first set the inclination and thencarry out electronic inclination alignment (see 7.7.4).5. Switch the tool on and then press the “inclined planemode” button. The “inclined plane mode” LED thenlights.The laser beam switches on as soon as the toolhas leveled itself. The PR 30-HVS can be inclinedas soon as “inclined plane mode” appears in thedisplay on the PRA 30.en12
7.7.2 Setting the slope manually 51. Press the inclination entry buttons (plus/minus) onthe PRA 30. To change the values more quickly,press and hold the inclination entry buttons forlonger. Depending on the angle at which the toolis already inclined, inclination values of up to 21.3%can be entered.NOTE If no button is pressed for three seconds,the tool will be set to the most recently displayedinclination value. The inclined plane mode LED thenblinks.NOTE If the tool measures a change in temperatureof more than 10 degrees, laser rotation stops forabout 40 seconds. During this time the tool correctsall errors that may have been caused by the tem-perature change. After this automatic correction thetool resets the laser plane to the previous inclinationand the laser again begins to rotate.Atthesametime,pressingthe“Minus”inclinationentry button lowers the laser plane in front of thetool and raises it behind the tool while the “Plus”inclination entry button raises the laser plane in frontof the tool and lowers it behind the tool.The LED display on the PRA 30 shows the angle ofinclination.7.7.3 Setting the inclination (slope) automaticallyWith this function you can create an inclined laser planebetween 2 points automatically and determine the angleof inclination between these points.1. Setuptherotatinglaseratthetopedgeoftheinclined plane like as described in 7.7.1.2. Mount the laser receiver with the PRA 80/PRA 83 re-ceiver holder, for example, on the PUA 50 telescopicstaff.3. Position the receiver immediately in front of therotating laser, bring it into alignment with the laserplane at the correct height, and then secure it on thetelescopic staff.4. Position the receiver on the telescopic staff at thelower edge of the inclined plane and double-clickthe “Automatic alignment” button. Double-click thebutton again to complete the procedure.The laser plane alignment procedure then begins. Aconstant signal tone is emitted while this is takingplace. The direction of the search can be changedby pressing the “Automatic alignment” button.As soon as the laser beam strikes the receiving win-dow of the PRA 30, the beam moves to the positionof the marking notch (reference plane). Once the po-sition is reached (i.e. the marking notch is found), anaudible signal with a duration of 5 seconds indicatesthat the process is complete.The “Automatic alignment” symbol is no longershowninthedisplayonthePRA30andthere-ceiver switches automatically to normal operatingmode.The inclination is shown in the display of the PRA 30for 5 seconds.5. Read the inclination between the two points (po-sitions of the rotating laser and the laser receiver)from the display of the PRA 30.NOTE The inclination disappears from the displayon the PRA 30 after being shown for 5 seconds.7.7.4 Optional electronic alignmentAfter aligning the rotating laser approximately and settingthe slope as described above, alignment of the PR 30-HVS can be optimized through use of Hilti’s patentedelectronic alignment system.1. Position the PRA 30 centrally opposite the PR 30-HVS at the end of the inclined plane. You can eitherhold it still by hand or fix it in place with the aid ofthe PRA 80 / PRA 83 .2. Activate electronic inclination alignment on thePR 30-HVS by pressing the “Electronic inclinationalignment” button.When the arrows for electronic inclination alignmentare blinking, the PRA 30 is receiving no laser beamfrom the PR 30-HVS.3. Whentheleftarrowlights,turnthePR30-HVSclockwise.4. When the right arrow lights, turn the PR 30-HVScounter-clockwise.When both arrows light, the PRA 30 is correctlyaligned.After successful alignment (both arrows light con-stantly for 10 seconds), the function ends automati-cally.5. Then secure the rotating laser on the tripod so thatit cannot be inadvertently moved out of position.6. You can also end electronic inclination alignmentby pressing the “Electronic inclination alignment”button.NOTE There may be deviations between the resultsobtained by approximate alignment with the sightingnotches and fine alignment with the aid of electronicinclination alignment. As the electronic method ismore accurate than the visual method, we recom-mend that electronic inclination alignment is alwaysused as the reference.7.7.5 Setting the inclination with the aid of thePRA 79 slope adapterNOTECheck that the slope adapter is fitted correctly betweenthe tripod and the tool (please refer to the operatinginstructions for the PRA 79).1. Set up the PRA 79 slope adapter in a suitableposition for the application, e.g. on a tripod.2. Position the tripod either at the upper edge or loweredge of the inclined plane.3. Mount the rotating laser on the slope adapter and,withtheaidofthetargetnotchontheheadofthe PR 30-HVS, adjust the tool and slope adapterso that they are parallel to the inclined plane. Thecontrol panel of the PR 30-HVS should face awayfrom the direction of inclination.en13
4. Make sure that the slope adapter is in the zeroposition (0°).5. Switch the tool on (see 7.2).6. Press the “Inclined plane mode” button.The “Inclined plane mode” LED then lights on thecontrol panel of the rotating laser.The tool then begins automatic self-leveling. Thelaser switches on and begins to rotate as soon asthis is complete.7. Settheslopeadaptertothedesiredangleofincli-nation.NOTE When the angle of inclination is set manually,the PR 30-HVS levels the laser plane once and thensubsequently fixes it. Vibration, changes in temper-ature or other influences that may occur during thecourse of the day may affect the position of the laserplane.7.8 Returning to standard modeTo return to standard operating mode, switch the tool offand then switch it back on again.7.9 Sleep modeThe PR 30-HVS can save power when in sleep mode.The laser is switched off, thereby extending battery life.7.9.1 Activating sleep mode1.

Press the “Units” button to deactivate the sleepmode on the PR 30-HVS.4. To ensure working accuracy, check the laser set-tings after the PR 30-HVS has been reactivated.8 Care and maintenance8.1 Cleaning and drying1. Blow dust off exit windows.2. Donottouchtheglasswiththefingers.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.8.2 Care of the Li-ion batteryAvoid ingress of moisture.Charge the battery fully before using it for the first time.In order to achieve maximum battery life, stop dischargingthe battery as soon as a significant drop in performanceis noticed.NOTEIf use of the tool continues, further battery discharge willbe stopped automatically before the battery cells sufferdamage. The tool switches itself off.Charge the battery with the Hilti charger approved for usewith Li-ion batteries.NOTE- A conditioning charge (as is required with NiCd orNiMH batteries) is not necessary.- Interruption of the charging procedure has no negativeeffect on battery life.- Charging can be started at any time with no negativeeffect on battery life. There is no memory effect (aswith NiCd or NiMH batteries).- For best results, batteries should be stored fullycharged in a cool dry place. Avoid charging the batteryin places subject to high ambient temperatures (e.g. ata window) as this has an adverse effect on battery lifeand increases the rate of self-discharge.- If the battery no longer reaches full charge, it mayhave lost capacity due to aging or overstressing. Itis possible to continue working with a battery in thiscondition but it should be replaced in good time.8.3 Storage1. Remove the appliance from its case if it has be-come wet. Dry and clean the tool, its transportcontainer and accessories (while observing the per-missible temperature range). Repack the equipmentonly once it is 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.
