discharging by the “Discharging Protection 
System”. When the battery is empty, the 
machine is switched off by means of a 
protective circuit: The inserted tool no longer 
rotates.
WORKING HINTS FOR YOUR 
TOOL
If your power tool becomes over heated, set 
the speed to maximum and run no load for 2-3 
minutes to cool the motor. SDS-plus tungsten 
carbide drill bits should always be used for 
concrete and masonry. 
When drilling in metal, only use HSS drill bits 
in good condition. Where possible use a pilot 
hole before drilling a large diameter hole.
PROBLEM SOLUTION
REASONS FOR DIFFERENT BATTERY 
PACK WORKING TIMES
Charging time problems, having not used a 
battery pack for a prolonged time will reduce 
the battery pack working time. This can be 
corrected after several charge and discharge 
operations by charging & working with your 
drill. Heavy working conditions such as large 
screws into hard wood will use up the battery 
pack energy faster than lighter working 
conditions. Do not re-charge your battery pack 
below 0
o
C and above 30
o
C as this will affect 
performance.
MAINTENANCE 
Remove the battery pack from the tool 
before carrying out any adjustment, 
servicing or maintenance.
Your power tool requires no additional 
lubrication or maintenance ,except for the 
cleaning & lubrication of the SDS bits and 
adaptors before inserting into the chuck.
 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.

To preserve natural resources, please 
recycle or dispose of the battery pack 
properly. This battery pack contains 
Li-Ion batteries. Consult your local waste 
authority for information regarding available 
recycling and/or disposal options. Discharge 
your battery pack by operating your tool, then 
remove the battery pack from the tool housing 
and cover the battery pack connections with 
heavy-duty adhesive tape to prevent short 
circuit and energy discharge. Do not attempt 
to open or remove any of the components.
