OPERATION MODE SWITCH
Rotary hammer drill features 2-function switch of the working mode (5). Depending on its setting, a drilling
only or impact drilling is possible (fig. C).
Impact drilling 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.
● Pos0 = regular drilling
●
Pos1 = impact drilling
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 (8).
Right rotation – set the switch (8) in the centreline of the switch (fig. B).
Left rotation – move the switch (8) 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.
●
Keep the rotary hammer drill in the axis of the hole. Keeping the drill perpendicular to the surface of the
processed material ensures the most effective operation. If a drill is not kept perpendicular to the surface
during operation, it may get jammed or broken in the hole, and injure the user.
Long lasting drilling at low rotational speed of the spindle may cause motor overheating. Make pe-
riodic breaks during operation or let the tool operate at maximum speed with no load for approxi-
mately 3 minutes. Do not cover holes for motor ventilation in the rotary hammer body.
