Choose position 2 for low torque/ High-speed
range for small diameter drill bits. If the gears do not

WORKING HINTS FOR YOUR IMAPCT DRILL
If your power tool becomes too hot, set the speed
to maximum and run no load for 2-3 minutes to cool
the motor. Tungsten carbide drill bits should always
be used for concrete and masonry. When drilling
in metal, only use HSS drill bits in good condition.
Always use a magnetic bit holder when using short
screwdriver bits.
Where possible use a pilot hole before drilling a large
diameter hole.
MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
Your power tool requires no additional lubrication 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.
