Pull the throttle lever (A) backwards, this willstop percussion, rotation <strong>and</strong> flushing water.2. Turn the feed control knob (C) to the closedposition.CBRe-positioning the pusher leg1. Switch off the rock drill percussion <strong>and</strong>flushing with the throttle lever (A).2. Depress the valve pin (B), whereupon thepiston rod is pulled back into the pusher legcylinder automatically (manually for BMK62S).. Re-position the pusher leg.4. Release the valve pin (B), whereupon thepiston rod moves outward again.5. Move the throttle lever (A) forward into theworking position.6. Note that the feed control knob (C) does notneed to be touched during this procedure.When you have finished drillingLay down the rock drill on a stone, wooden plankor similar object, so as to prevent drill cuttings <strong>and</strong>other foreign matter from entering the chuck.Turn off the water pressure before the air pressure.Run the rock drill for a few seconds to clean outwater <strong>and</strong> moisture after the water has been shutoff.MaintenanceRegular maintenance is a prerequisite for machinesafety. Replace damaged <strong>and</strong> worn componentsin good time. For a major service to the machine,contact your nearest authorized workshop.Check the machine <strong>and</strong> tools for wear <strong>and</strong> damageat regular intervals. Do not use very worn ordamaged tools.When cleaning mechanical parts with a solvent,make sure that you comply with current health<strong>and</strong> safety regulations <strong>and</strong> ensure that there issufficient ventilation.Daily maintenance, regular checking of wearingparts <strong>and</strong> carrying out repairs in good timeprevents breakdowns <strong>and</strong> increases the service lifeof the machine.Always oil the rock drill <strong>and</strong> pusher leg well,before you put them into storage.Store in a clean <strong>and</strong> dry place.Make sure that no foreign matter enters themachine.Always hose down <strong>and</strong> wipe clean the rock drill<strong>and</strong> pusher leg after use.14© 2006 Atlas Copco Construction <strong>Tools</strong> AB | No. 9800 0680 71 | 2006-11-20
