required during hammer work efficiency is low. Open 
the grease box lid at the top of the hammer using the pin 
spanner provided. Then refill approx 30g grease provided 
with your tool. The grease specification is general purpose 
lithium based. 

Caution: Keep the container of grease 
away from children.

8. OVERLOAD PROTECTION 

If the tool insert becomes caught or jammed, the drive to the 
drill spindle is interrupted. Because of the forces that occur, 
always hold the power tool firmly with both hands and 
provide for a secure stance.

WORKING HINTS FOR 

YOUR TOOL

●

  Reduce the pressure on the drill bit when it is about to 

break through. This will prevent the drill from jamming. 

●

  When drilling a large hole, first drill a pilot hole using a 

smaller drill bit.

●

  Always apply pressure to your drill bit in a straight line, 

and if possible at right angles to the workpiece.

●

  Never change the operating mode whilst the rotary 

hammer is running.

●

  Do not apply excessive pressure to the tool when 

chiseling. Expressive force does not speed up the work.

MAINTENANCE

Remove the plug from the socket before 
carrying out any adjustment, servicing or 
maintenance.

There are no user serviceable parts in your power tool. 
Never use water or chemical cleaners to clean your power 
tool. Wipe clean with a dry cloth. Always store your power 
tool in a dry place. Keep the motor ventilation slots clean. 
Keep all working controls free of dust. Occasionally you may 
see sparks through the ventilation slots. This is normal and 
will not damage your power tool. 
If the supply cord is damaged, it must be replaced by 
the manufacturer, its service agent or similarly qualified 
persons in order to avoid a hazard.

TROUBLESHOOTING

1.   If your power tool does not start, check the plug on the 

power supply first.

2.   If your hammer becomes too hot in use, set the hammer 

switch to the drill mode and allow your drill to operate at 
maximum speed without load for 2 minutes.

3.   If your hammer work efficiency is too low, please add 

sufficient grease in the grease box.

4.   If work efficiency is too low please check drill bit or 

chisel and make sure it is not blunt or worn.

5.   If a fault cannot be rectified, return the tool to an 

authorized dealer for repair.
