Operating instructions
Switch operation
Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the type plate of the
power tool.
To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill bits and other
various parts are installed or removed. The power switch should also be turned off during a work break and after work.
Switch on: Press the switch towards① position.
Switch off: Release the switch towards ② position.
When drilling at “ro hammering”
If you switch the function knob during motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Be
sure to switch the function knob when the motor is at a complete stop.
(1) Switching to “ro hammering”
Turn the function knob clockwise. Align
of the function knob and of the cover as illustrated in Fig.5.
(2) Mount the drill bit.
(3) Pull the trigger switch after applying the drill bit tip to the drilling position Fig.6
(4) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes out gradually is sufficient.
CAUTION:
Although this machine is equipped with a safety clutch, if the drill bit becomes bound in concrete or other material, the resultant stoppage of the drill bit could
cause the machine body to turn in reaction. Ensure that the main handle and side handle are gripped firmly during operation.
When chipping and chiselling at “hammering”
CAUTION:
- If the function knob is switched during motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Make sure to switch the function
knob when the motor is at a complete stop.
- If the tine chisel or flat chisel is used at the position of “rotation hammering”, the tool can start to rotate, resulting in unexpected accidents. Make sure that
they are used at the position of “hammering”.
(1) Switching to “hammering”
Turn the function knob counter-clockwise. Align
of the function knob and of the cover as illustrated in Fig. 7.
(2) When fixing working positions of flat chisel such as cold chisel, etc.,
(a) Turn the function knob, Align of the function knob and of the cover as illustrated in Fig. 8.
(b) Turn the bit as illustrated in Fig. 9 and fix the flat chisel to the desired working direction.
(c) Switch the selector lever to “hammering” according to the procedures mentioned in the above item (1) and secure the position of the tool.
5. Warming up (Fig.10)
The grease lubrication system in this unit may require warming up in cold regions.
Position the end of the bit so makes contact with the concrete, turn on the switch and perform the warming up operation. Make sure that a hitting sound is
produced and then use the unit.
CAUTION:
When the warming up operation is performed, hold the side handle and the main body securely with both hands to maintain a secure grip and be careful not
to twist your body by the jammed drill bit.
The scale’1’ of the speed adjuster knob is designed for a minimum speed with the number of 300 rotations per minute and 1950 times of blow per minute. The
scale ‘6’ is designed for a maximum speed with the number of 760 rotations per minute and 4860 times of blow per minute.
CAUTION:
Do not adjust the speed adjuster knob during operation. Doing so can result in injury because the Rotary Hammer must be held by only one hand, disabling
the steady control of the Rotary Hammer.
5. Indicator LEDS (Fig. 4)
The green power-ON indicator LED lights up when the tool is plugged. If indicator led does not light up, the mains cord or the controller may be detective. The
red service indicator LED lights up when the carbon brushes are worn out to indicate that the tool needs servicing.

How to replace grease
Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without replacing the grease. Please contact the nearest service
center for grease replacement when any grease is leaking from loosened screw.
Further use of the rotary hammer with lock off grease will cause the machine to seize up reduce the service life.
CAUTION:
A special grease is used with this machine, therefore, the normal performance of the machine may be badly affected by use of other grease. Please be sure to
let one of our service agents undertake replacement of the grease.
When you have to replacement the grease by yourself, please following the order (any damage resulting from this procedure is not covered by the warranty):
CAUTION:
Before replenishing the grease, turn the power off and pull out the power plug.
(1) Remove the oil tank cover and wipe off the grease inside.
(2) Supply 30g of Electric Hammer Grease (accessory contained in tube) to the crank case.
(3) After replenishing the grease, install the oil tank cover securely.
NOTE:
The Electric Hammer Grease is of the low viscosity type. If necessary purchase from an Bormann Authorized Service Center.
