OPERATION MODE SWITCH
Rotary hammer drill features 3-function switch of the working mode ( 5 ). Depending on its setting, a drilling
only, impact drilling or chiselling is possible ( fig. C ).
Impact drilling and chiselling requires to slightly press the rotary hammer. Too great pressure would cause
unnecessary, excessive load of the motor. Check technical condition of the working tools regularly. Sharpen
or replace working tools when needed.
Press the switch lock button ( a ) prior to change of position of the working mode switch ( 5 ) ( fig. C ).

= chiselling (symbol of a chisel and a hammer)
Do not try to change position of the working mode switch when the motor of rotary hammer drill is
operating. Such action may lead to serious damage of the rotary hammer drill or even injury of the
user. Do not use three-jaw drill chuck, when the rotary hammer drill is set to impact drilling. This
chuck is designed for regular drilling only (in wood or steel).
LEFT – RIGHT DIRECTION OF ROTATION
Choose direction of rotary hammer drill spindle rotation with the selector switch ( 9 ).
Right rotation – set the switch ( 9 ) in the centreline of the switch ( fig. B ).
Left rotation – move the switch ( 9 ) to the extreme right position.
* The possibility is reserved that in certain cases position of the switch relating to rotation direction may be different than
specified. Please refer to graphic signs placed on the switch or tool body.
Do not change direction of rotation when the spindle of the rotary hammer drill is rotating. Ensure
the position of the selector switch is correct before starting the tool. Do not use left direction of
rotation when impact function is on.
DRILLING HOLES
●
When drilling a hole with large diameter, it is recommended to drill smaller hole and then ream it to
desired diameter. It prevents overloading the rotary hammer drill.
When drilling deep holes drill gradually to smaller depths, then slide the drill out of the hole to remove
●
borings and dust.
If a drill jam occurs during drilling, the overload clutch will work. Turn off the rotary hammer immediately
●
to prevent its damage. Remove jammed drill from the hole.
