Description2.1 Use of the product as directedThe Hilti PRA 35 can be used to remotely control the PR 35 rotating laser and to detect and locate the laserbeam. These operating instructions apply only to operation of the PRA 35 laser receiver. For information aboutthe remote control functions, please refer to the operating instructions for the PR 35.In conjunction with the PR 35, the tool can be used to determine, transfer and check horizontal levels andheights, verticals, inclined planes and right angles, e.g. transferring datums and height marks, determining orchecking right angles for walls, vertical alignment from a reference point and setting out slopes.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 tool where there is a risk of fire orexplosion.Modification of the tool or tampering with its parts is not permissible.2.2 FeaturesThe tool can be held by hand or mounted on a leveling staff, timber batten or frame etc., using the applicableholder.2.3 IndicatorsNOTEThe display of the PRA 35 laser receiver uses several symbols to indicate various modes or statuses.Indication of the position of the receiver relativeto the laser planeThe position of the receiver relative to the laser plane isshown by an arrow indicating the direction in which thereceiver has to be moved in order to bring it exactly intoalignment with the laser.Battery status indicator The battery status indicator shows the remaining batterycapacity.en2
Volume level When no volume level symbol is visible in the display, thevolume level is set to zero (off). If 1 column is shown,the volume is set to “quiet”. If 2 columns are shown, thevolume is set to “normal”. If 3 columns are shown, thevolume is set to “loud”.Offset indicator Shows the exact distance of the receiver from the laserplane in the desired measuring units.Other indicators Other indicators in the display refer to the PR 35 rotatinglaser when controlled remotely. For further information,please refer to the PR 35 operating instructions.2.4 Items supplied1 PRA 35 remote control / laser receiver1 PRA 35 operating instructions2 Batteries1 Manufacturer’s certificate3.

4. Safety instructions4.1 Basic information concerning safetyIn addition to the information relevant to safetygiven in each of the sections of these operatinginstructions, the following points must be strictlyobserved at all times.4.2 General safety rulesa) Keep other persons, especially children, awayfrom the area in which the work is being carriedout.b) Check the condition of the tool before use. If thetool is found to be damaged, have it repaired ata Hilti service center.c) Have the tool repaired only at a Hilti servicecenter.d) Do not render safety devices ineffective and donot remove information and warning notices.e) The tool must be checked at a Hilti servicecenter after it has been dropped or subjected toother mechanical stresses.f) If mounting on an adapter, check that the toolis fitted correctly.g) To avoid measurement errors, the receivingarea must be kept clean.h) Although the tool is designed for the tough con-ditions of jobsite use, as with other optical andelectronic instruments (e.g. binoculars, spec-tacles, cameras) it should be treated with care.i) Although the tool is protected to prevent entryof dampness, it should be wiped dry each timebefore being put away in its transport container.j) To avoid hearing damage, hold the tool asfar away as possible from your ear (and otherpersons’ ears).4.2.1 Electricala) Keep the batteries out of reach of children.b) Do not allow the batteries to overheat and do notexpose them to fire. The batteries may explodeor release toxic substances.c) Do not charge the batteries.d) Do not solder the batteries into the tool.e) Do not discharge the batteries by short circuitingas this may cause them to overheat and presenta risk of personal injury (burns).f) Do not attempt to open the batteries and do notsubject them to excessive mechanical stress.4.3 Proper organization of the work areaa) Avoid unfavorable body positions when workingon ladders or scaffolding. Make sure you workfrom a safe stance and stay in balance at alltimes.b) Use the tool only within its specified limits.c) Measurements taken through or from panes ofglass or through other objects may be inaccurate.d) Use of the telescopic staff in the vicinity of over-head high voltage cables is not permissible.e) Reflection of the laser beam from glass or otherreflective surfaces may cause errors or incorrectresults.4.4 Electromagnetic compatibilityAlthough the tool complies with the strict require-ments of the applicable directives, Hilti cannot en-tirely rule out the possibility of the tool being subjectto interference caused by powerful electromagneticradiation, leading to incorrect operation. Check theaccuracy of the tool by taking measurements by othermeans when working under such conditions or if youare unsure. Likewise, Hilti cannot rule out the pos-sibility of interference with other devices (e.g. aircraftnavigation equipment).en4
