Description 2.1 Use of the product as directed The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles. Examples of its uses are: transferring datums and height marks, determining right angles for walls, vertical alignment on reference points and setting out slopes. Use of tools or AC adapters which show visible signs of damage is not permissible. Operation outdoors or in damp conditions in âCharging during operation modeâ is not permissible. 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 or explosion. Modification of the tool is not permissible. 2.2 PR 35 rotating laser The Hilti PR 35 is a rotating laser tool with a visible rotating laser beam and a reference beam set at 90° to the main beam. The PR 35 can be used for alignment in the vertical, horizontal and inclined planes. 2.3 Features The tool makes it possible for a single person to level or align in any plane quickly and with great accuracy. The tool features automatic leveling (within 10° (Âą5°)). The tool levels itself automatically after switching on. The laser beam is emitted only when the specified accuracy has been achieved. LEDs indicate the toolâs current operating status. The tool is powered by a rechargeable Liâion battery which can be charged while the tool is in operation. The PR 35 has a number of useful features: Monitoring mode, auto-alignment, sleep mode and button lock. 2.4 PRA 35 combined remote control and laser receiver The PRA 35 is a combined remote control unit and laser receiver. It can be used to control the PR 35 rotating laser over great distances. The PRA 35 also serves as a laser receiver and can thus be used to detect and indicate the laser beam at great distances. 2.5 Digital distance measurement display The PRA 35 shows the distance between the laser plane and the marking notch on the PRA 35 in the digital display. This allows the user to determine the exact position of the receiver relative to the laser plane, with millimeter accuracy, in a single operation. 2.6 Speed of rotation / line function 3 speeds of rotation are available for use (300, 600, 1200 /min). It is possible to switch between the individual functions such as rotation and line functions. This is possible with the PR 35 rotating laser and with the PRA 35. The line function improves laser beam visibility and limits the laser beam to a certain working area. 2.7 Automatic alignment and monitoring Using the PR 35 and the PRA 35, a single person can align the laser plane automatically with a certain point with great accuracy. When required, the laser plane can be checked at regular intervals with the aid of the monitoring function and the PRA 35 in order to avoid possible deviations due to temperature fluctuations, wind or similar. 2.8 Digital slope display with patented electronic axis alignment The digital slope display can indicate a slope of up to 15%. This makes it possible to set out and check slopes without having to make any calculations. 2.9 Shock warning The tool goes into warning mode if it is knocked off level (due to vibration or impact) while in operation: all LEDs blink and the laser switches off (the laser head no longer rotates). en en 2.10 Automatic cut-out The laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range or movement is blocked mechanically. After switching the tool on, the shock warning only becomes active 1 minute after completion of leveling. If a button is pressed within this time (before 1 minute has elapsed), the 1 minute delay before activation begins again. 2.11 Items supplied PR 35 rotating laser PRA 35 remote control / laser receiver PRA 80 receiver holder PR 35 operating instructions Target plate Manufacturerâs certificate PRA 84 Liâion battery PRA 85 AC adapter Hilti toolbox 2.12 Operating status indicators Operating status is indicated as follows: auto-leveling LED, battery status LED, shock warning LED and slope LED. 2.13 LED indicators Auto-leveling LED (green) Shock warning LED (orange) Monitoring LED (orange) Slope LED (orange) Several LEDs light All LEDs The green LED blinks.

Safety instructions 5.1 Basic information concerning safety In addition to the information relevant to safety given in each of the sections of these operating instructions, the following points must be strictly observed at all times. 5.2 General safety rules a) Do not render safety devices ineffective and do not remove information and warning notices. b) Keep laser tools out of reach of children. c) Failure to follow the correct procedures when opening the tool may cause emission of laser radiation in excess of class 2. Have the tool repaired only at a Hilti Service Center. d) Take the influences of the surrounding area into account. Do not use the tool where there is a risk of fire or explosion. e) (Statement in accordance with FCC §15.21): Changes or modifications not expressly approved by the manufacturer can void the userâs authority to operate the equipment. 5.3 Proper organization of the work area a) Secure the area in which you are working and take care to avoid directing the beam towards other persons or towards yourself when setting up the tool. b) Avoid unfavorable body positions when working from ladders. Make sure you work from a safe stance and stay in balance at all times. c) Measurements taken through panes of glass or other objects may be inaccurate. d) Ensure that the tool is set up on a steady, level surface (not subject to vibration). e) Use the tool only within its specified limits. f) Check that your PR 35 is responding only to your PRA 35 and not to other PRA 35s that may be in use on the jobsite. 5.3.1 Electromagnetic compatibility Although the tool complies with the strict requirements of the applicable directives, Hilti cannot entirely rule out the possibility of the tool being subject to interference caused by powerful electromagnetic radiation, leading to incorrect operation. Check the accuracy of the tool by taking measurements by other means when working under such conditions or if you are unsure. Likewise, Hilti cannot rule out the possibility of interference with other devices (e.g. aircraft navigation equipment). 5.3.2 Laser classification for laser class II appliances The tool complies with Laser Class 2 in accordance with IEC825-1:2008 / EN60825-1:2008 and Class II in accordance with CFR 21 § 1040 (FDA). This tool may be used without need for further protective measures. The eyelid closure reflex protects the eyes when a person looks into the beam unintentionally for a brief moment. This eyelid closure reflex, however, may be negatively affected by medicines, alcohol or drugs. Nevertheless, as with the sun, one should not look directly into sources of bright light. Do not direct the laser beam toward persons. 5.4 General safety rules a) Check the condition of the tool before use. If the tool is found to be damaged, have it repaired at a Hilti service center. b) The user must check the accuracy of the tool after it has been dropped or subjected to other mechanical stresses. en c) When the tool is brought into a warm environment from very cold conditions, or vice-versa, allow it to become acclimatized before use. d) If mounting on an adapter, check that the tool is screwed on securely. e) Keep the laser exit aperture clean to avoid measurement errors. f) Although the tool is designed for the tough conditions of jobsite use, as with other optical and electronic instruments (e.g. binoculars, spectacles, cameras) it should be treated with care. g) Although the tool is protected to prevent entry of dampness, it should be wiped dry each time before being put away in its transport container. h) Check the tool before using it for important measuring work. i) Check the accuracy of the measurements several times during use of the tool. j) Use the AC adapter only for connecting to the AC supply. k) Check to ensure that the tool and AC adapter do not present an obstacle that could lead to a risk of tripping and personal injury. l) Ensure that the workplace is well lit. m)Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. n) Check the condition of the extension cord and replace it if damage is found. Do not touch the AC adapter if the extension cord or AC adapter are damaged while working. Disconnect the supply cord plug from the power outlet. Damaged supply cords or extension cords present a risk of electric shock. o) Do not expose the supply cord to heat, oil or sharp edges. p) Never operate the AC adapter when it is dirty or wet. Dust (especially dust from conductive materials) or dampness adhering to the surface of the AC adapter may, under unfavorable conditions, lead to electric shock. Dirty or dusty tools should thus be checked at a Hilti Service Center at regular intervals, especially if used frequently for working on conductive materials. q) Avoid touching the contacts. 5.4.1 Battery tool use and care a) Check that the tool is switched off before fitting the battery. Use only the Hilti battery approved for use with this tool. b) Do not expose batteries to high temperatures or fire. This presents a risk of explosion. c) Do not disassemble, squash or incinerate batteries and do not subject them to temperatures over 75°C. A risk of fire, explosion or injury through contact with caustic substances may otherwise result. d) Avoid ingress of moisture. Moisture may cause a short circuit resulting in a risk of burning injury or fire. e) Do not use batteries other than those approved for use with the applicable tool or appliance. Use of other batteries or use of the battery for purposes for which it is not intended presents a risk of fire and explosion. f) Observe the special instructions applicable to the transport, storage and use of Li-ion batteries. g) Avoid short-circuiting the battery. Before inserting the battery in the tool, check that the terminals of the battery and the tool are free from foreign objects. Short-circuiting the battery terminals presents a risk of fire, explosion or contact with caustic substances. h) Do not charge or continue to use damaged batteries (e.g. batteries with cracks, broken parts, bent or pushed-in and/or pulled-out contacts). i) Use only the specified battery to power the tool and use only the PRA 85 AC adapter or PRA 86 car charging connector for charging. Failure to observe these points may result in damage to the tool. 6.

In order to ensure that the toolâs specified accuracy can be maintained, make sure that it is set up on a level surface or mounted sufficiently level on the tripod or other accessory. 4. Press the âOn / offâ button. After the tool has leveled itself automatically, it projects a stationary laser beam vertically downwards. This projected point is the reference point and is used to position the tool. 7.5.1 Manual alignment Manual alignment of the vertical plane is carried out by pressing the âUpâ or âDownâ buttons on the rear of the PRA 35. 7.5.2 Auto-alignment Hold the PRA 35 at the point to be aligned, with the receiving side facing the PR 35, and then press the âAutomatic alignmentâ button. The laser plane alignment procedure then begins. A constant signal tone is emitted while this is taking place. 12 The search can be adjusted by pressing the âDirectionâ buttons. As soon as the laser beam strikes the receiving area of the PRA 35, the beam moves to the position of the marking notch (reference plane). A short signal tone is emitted, indicating the end of the procedure, as soon as the laser beam finds the position of the marking notch. 7.6 Working with slopes NOTE For optimum results, check that the PR 35 is correctly aligned. This is best done by selecting 2 points each 5 m to the left and right of the tool but parallel to the tool axis. Mark the height of the horizontal plane and then, after setting the slope, mark the heights. The tool is aligned optimally only when these heights are identical at both points. 7.6.1 Setting up NOTE The slope can be set manually, automatically, or by using the PRA 76/78 slope adapter. 1. Set up the tool in a suitable position for the application, e.g. on a tripod. 2. With the aid of the target notch on the head of the PR 35, bring the tool parallel to the inclined plane. 3. Press the âOn / offâ button for at least 8 seconds until the orange LED lights. 4. The laser beam switches on as soon as the tool has leveled itself. The PRA 35 can then be set to the desired slope. 7.6.2 Setting the slope manually Press the âUpâ and âDownâ arrow buttons on the PRA 35 remote control. Pressing the arrow buttons for longer causes the values to change more quickly. The LED display on the PRA 35 shows the angle of slope. If no button is pressed for 3 seconds, the tool will be set to the most recently displayed value. 7.6.3 Setting the slope automatically NOTE The slope can be set automatically only when slope mode is active and when a PRA 35 laser receiver is used. Incline the laser as described at 7.5.2, but in alignment with the inclined plane. 7.6.4 Optional electronic alignment After setting the slope as described above, alignment of the PR 35 can be optimized by Hiltiâs patented electronic alignment system. 1. Position the PRA 35 centrally opposite the PR 35 at the end of the inclined plane. It can be held still by hand or fixed in place with the aid of the PRA 80. 2. Switch the PRA 35 on. 3. Activate electronic alignment on the PR 35 by pressing the âLeftâ arrow button. 4. If the shock warning / slope LEDs blink, the PRA 35 is not receiving the laser beam from the PR 35. 5. If the shock warning / monitoring LEDs blink, realign the PR 35 by moving it counterclockwise. 6. If the slope / monitoring LEDs blink, realign the PR 35 by moving it clockwise. 7. If the monitoring LED blinks, alignment is correct. 8. End electronic alignment mode by pressing the âRightâ arrow button. 7.6.5 Setting the slope with the aid of the PRA 76/78 slope adapter NOTE Check that the slope adapter is fitted correctly between the tripod and the tool (please refer to the operating instructions). 7.7 Monitoring The monitoring function checks at regular intervals whether the plane that is set (vertical, horizontal or inclined) has been altered inadvertently (e.g. by vibration). If this is the case, the projected plane will be realigned to the zero point (i.e. the marking notch on the PRA 35) (so long as it is still within the receiving area). A PRA 35 is required for use of the monitoring function. An additional laser receiver can be used to detect the laser beam while the laser beam is being monitored. 1. Preparation for activation of the monitoring function is basically the same as the procedure for activation of automatic alignment mode. 2. Position the tool at the desired starting point 1 and switch it on. 3. Position PRA 35 laser receiver at the reference point (point 2) on the axis and secure it there. The PRA 751 can be used to secure it. The tool (point 1) and the PRA 35 (point 2) then form anchor points on the plane. Take care to ensure that the marking notch on the PRA 35 is at exactly the height at which the rotating laser is later to project the laser line or point. The red laser receiving surface on the PRA 35 must face the rotating laser. 4. Take care to ensure there are no obstructions between the rotating laser and the PRA 35 laser receiver which could interfere with communication between the devices. Glass and other translucent materials may also interfere with communication between the devices. Reflections from windows may also cause interference. 5. Switch the PR 35 and the PRA 35 on. The monitoring function can be activated by pressing the âMonitoring modeâ button on the PRA 35. 6. The system is then in monitoring mode. The function is indicated in the display on the PRA 35 by two regularly blinking arrows pointing toward the axis in which alignment is to be carried out. 7. The monitoring system checks at regular intervals whether the laser plane has shifted. If it is found to have shifted, the laser plane will be readjusted to the original marking plane as far as possible. If the marking plane is outside the self-levelling range (10° (Âą5°)) or the line of sight between the rotating laser and the laser receiver is blocked for a certain length of time, an error message is displayed. 7.8 Returning to standard mode In order to return to standard mode, horizontal alignment, 300 /min, the tool must be switched off and restarted. 7.9 Sleep mode The PR 35 saves power when in sleep mode. The laser is switched off, thereby extending battery life. Activate sleep mode by pressing the âSleep modeâ button on the PRA 35. Deactivate sleep mode by pressing the âSleep modeâ button on the PRA 35 again. After reactivating the PR 35, check the laser settings in order to ensure accuracy. 13 en 7.10 Working with the target plate The target plate improves laser beam visibility. The target plate should be used in bright conditions or whenever improved laser beam visibility is desired. Simply bring the target plate into the plane of the projected laser beam. The target plate is made from a material that makes the laser beam more easily visible. en 8. Care and maintenance 8.1 Cleaning and drying 1. Blow dust off the lenses. 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 little water. NOTE Abrasive cleaning materials may scratch the glass and impair the accuracy of the laser tool. NOTE Do not use any other liquids as these may damage the plastic components. 4. Observe the temperature limits when storing your equipment. This is particularly important in winter / summer if the equipment is kept inside a motor vehicle (-30°C to +60°C). 8.2 Storage Remove the tool from its case if it has become wet.

CAUTION Always remove the batteries before shipping the tool. 8.4 Hilti Calibration Service We recommend that the tool is checked by the Hilti Calibration Service at regular intervals in order to verify its reliability in accordance with standards and legal requirements. 14 Use can be made of the Hilti Calibration Service at any time, but checking at least once a year is recommended. The Calibration Service provides confirmation that the tool is in conformance, on the day it is tested, with the specifications given in the operating instructions. The tool will be readjusted if deviations from the manufacturerâs specification are found. After checking and adjustment, a calibration sticker applied to the tool and a calibration certificate provide written verification that the tool operates in accordance with the manufacturerâs specification. Calibration certificates are always required by companies certified according to ISO 900x. Your local Hilti Center or representative will be pleased to provide further information. 8.4.1 Checking accuracy In order to ensure compliance with the technical specifications, the tool should be checked regularly (at least before each major / relevant job). 8.4.1.1 Checking the main and transverse horizontal axes 15 1. Set up the tripod approx. 20 m from a wall and level the tripod head with a spirit level. 2. Mount the tool on the tripod and use the aiming notch to aim the tool at the wall. 3. Use the receiver to catch the laser beam and mark a point (point 1) on the wall. 4. Pivot the tool clockwise through 90° about its own axis. In doing so, ensure that the height of the tool does not change. 5. Use the laser receiver to catch the laser beam and mark a second point (point 2) on the wall. 6. Repeat steps 4 and 5 twice and mark points 3 and 4 on the wall with the aid of the laser receiver. When this procedure is carried out carefully, the vertical distance between the two marked points 1 and 3 (main axis) or, respectively, points 2 and 4 (transverse axis) should be less than 3 mm (at 20 m). If the deviation is greater than this, the tool should be returned to a Hilti Service Center for calibration. 8.4.1.2 Checking the vertical axis 16 17 1. Place the tool in the vertical position on a flat floor approx. 20 m from a wall. 2. Adjust the position of the tool so that the grips are parallel 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) at the base of the wall (set the rotating laser to medium speed). 5. With the aid of the receiver, mark point (B) at a height of approx. 10 m. 6. Pivot the tool through 180° and realign it with the reference point (R) on the floor and with point (A) at the base of the wall. 7. With the aid of the receiver, mark point (C) at a height of approx. 10 m. NOTE When the procedure has been carried out carefully, the horizontal distance between the two points (B) and (C) marked at a height of 10 meters should be less than 1.5 mm (at 10 m). If the deviation is greater: Please return the tool to a Hilti Service Center for calibration. 9. Troubleshooting Fault Possible cause Remedy The display shows this symbol The button lock is active.
