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
1. 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 tool.
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.
