the actual conditions of use should also take account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle but not actually doing the job. This may significantly reduce the exposure level over the total working period. Helping to minimise your vibration exposure risk. ALWAYS use sharp chisels, drills. Maintain this tool in accordance with these instructions and keep well lubricated (where appropriate).
Operating instructions note: Before using the tool, read the instruction book carefully. Intended Use The machine is intended for hammer drilling in concrete, brick and stone as well as for light chiseling work. It is also suitable for drilling without impact in wood, metal, ceramic and plastic. Warning! Before any work on the machine itself, pull the mains plug. 1 INSERTING AND REMOVING DRILL BITS IN THE SDS-plus CHUCK Take care that the dust protection cap is not damaged when changing tools.
2 ATTACHING AND REMOVING THE CHUCK Note: Ensure the Function Mode Selection Switch (3) is not in the chisel rotation mode( ) or the chuck cannot be removed. Chuck icons: “ “unlock “ “lock 1) REMOVING THE CHUCK (See Fig. B1) Firmly turn the Rotary Sheath(b) as far as possible in the direction noted by the unlock Icon“ “(clockwise) then pull the chuck(1) off. After removing, clean the chuck and spindle of any debris fragments and apply lubrication to the chuck for protection. 2) ATTACHING THE CHUCK (See Fig.
5 USING THE DEPTH GAUGE (See Fig. C) The Depth Gauge(2) can be used to set a constant depth to the drill. Fit the drill bit into the chuck. Loosen the depth gauge by rotating the locking screw (c) anti-clockwise. Slide the depth gauge until the distance between the depth gauge end and the drill bit end is equal to the depth of hole/screw you wish to make. Then clamp the depth gauge by rotating the locking screw (c) clockwise. 6 ON/OFF SWITCH WITH VARIABLE SPEED CONTROL (See Fig.
For drilling into steel, wood and plastics choose the Rotary drilling position. For simultaneous drilling and impacting of concrete or masonry, choose the Hammer drilling position. Chisel rotation position for adjustment of the chiselling position.(Non-work position) For impacting only - for light chipping, chiseling and demolition applications choose the Hammer position. Warning! The operating mode selector switch may be actuated only at a standstill.
9 LUBRICATION MACHINE (See Fig. F) The machine is grease-lubricated. A grease refill is only required during hammer work efficiency is low. Open the grease box lid at the top of the hammer using the pin spanner. Then refill approx 30g grease. Caution: Keep the container of grease away from children. e 10 REPLACE THE BRUSHES (See Fig. G1,G2,G3) When the resin insulating tip (g) inside the carbon brush (h) is exposed to contact the commutator (f) , it will automatically shut off the motor.
1 2 3 4 5 Working hints for your tool Trouble shooting Reduce the pressure on the drill bit when it is about to break through. This will prevent the drill from jamming. When drilling a large hole, first drill a pilot hole using a smaller drill bit. Always apply pressure to your drill bit in a straight line, and if possible at right angles to the workpiece. Never change the operating mode whilst the drill is running. Do not apply excessive pressure to the tool when chiseling.
