INSTALLATION AND REPLACEMENT OF WORKING TOOLS
Hammer drill is designed to operate with working tools with SDS-PLUS shanks.
Prior to starting operation clean the hammer drill and working tools. Use grease and apply thin layer onto
shank of the working tool. It will improve tool durability.
Disconnect the power tool from power supply.
Put the hammer against work bench.
Hold the fixing sleeve (2) of the SDS chuck (1) and pull it to the back, overcoming the spring resistance .
Insert working tool shank into the chuck and slide it to mechanical stop (it may be necessary to turn
the working tool so it can reach appropriate position) (fig. A).
Release the fixing sleeve (2), it will finally fix the tool.
Working tool is properly seated if it cannot be removed without pulling off the fixing sleeve.
If the sleeve does not return to its default position, remove the working tool and repeat the whole
operation.
High efficiency of the hammer drill operation can be achieved by using sharp and undamaged
working tools.
DEINSTALLATION OF WORKING TOOL
Just after the operation is finished, the working tool may be hot. Avoid direct contact and use
appropriate protective gloves. Clean the working tool after removal.
Disconnect the power tool from power supply.
Pull the fixing sleeve (2) to the back and hold.
Remove the working tool with your second hand by pulling it to the front.
OVERLOAD CLUTCH
Hammer drill is equipped with factory set overload clutch. Spindle of the hammer drill stops immediately
after working tool jams, which might overload the power tool.
USE OF ANTI-DUST COVER
Anti-dust cover is round, rubber casting of appropriate shape. It is placed on the drill to catch dust when
drilling in ceiling for example. Put the cover on a drill, bring the drill close to the surface and move the cover
along the drill until it reaches surface of the processed material. As the tool gets deeper into the material,
the cover slides on the drill and catches the dust produced. Empty the cover from time to time.
Always use glasses or anti-splinter goggles, especially when drilling a hole above your head.
SWITCHING ON / SWITCHING OFF
The mains voltage must match the voltage on the rating plate of the hammer drill.
Switching on – press the switch button (5) and hold in this position (fig. B).
Switching off – release pressure on the switch (5).
OPERATION MODE SWITCHES
Hammer drill features two switches of the working mode: impact mode switch (6) (fig. D) and drilling mode
switch (3) (fig. E). Depending on its settings, a drilling only, impact drilling or chiselling is possible. Impact
drilling and chiselling require to slightly press the hammer drill. Excessive pressure would cause excessive
motor load. Check technical condition of the working tools regularly. Sharpen or replace working tools
when needed.
Appropriate setting of switches for each of the functions is shown on (fig. F).
