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.
