can be bored by rotation only. Such action will not only reduce drill efficiency, but may 

also damage the drill tip. Operating the Impact Drill with the change lever in mid-posi-

tion may result in damage. When switching, make sure that you shift the change lever 

to the correct position. 

how to use

ATTENTION

To prevent accidents, make sure to turn the switch off and disconnect the plug from 

the receptacle when the drill pits and other various parts are installed or removed. The 

power switch should also be turned off during a work break and after work.

Switch operation

This  rotary  hammer  can  be  used  in  hammering,  rotation  +  hammering  and  drilling 

modes. Before operation set both switches in needed mode.

ATTENTION

Application of force more than necessary will not only reducing drilling efficiency at 

all, but will deteriorate the tip edge of the drill bit and reduce the service life of the 

rotary hammer in addition.

Do not attempt to drill anchor holes or holes in concrete with the main unit in the rota-

tion only function.

Do not attempt to use the rotary hammer in the rotation and striking function with the 

drill chuck and chuck adaptor attached. This would seriously shorten the service life of 

every components of the machine.

 Maintenance anD inspection

1. Inspecting the drill bits.

Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace 

the drill bit with a new one or resharpening without delay when abrasion is noted.

2. Inspecting the screws

Regularly  inspect  all  mounting  screws  and  ensure  that  they  are  properly  tightened. 

Should any of the screws be loose, retighten them immediately. Failure to do so could 

result in serious hazard.

3. Maintenance of the motor. 

The motor unit winding is the very “heart” of the power tool. Exercise due care to en-

sure the winding does not become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes. 

The motor is equipped with carbon brushes, which wear with time. When a brush reach-

es the wear limit, the motor may malfunction. If the engine is equipped with a disengag-
