WORKING HINTS FOR
YOUR TOOL
1. Reduce the pressure on the drill bit when it is about
to break through. This will prevent the drill from
jamming.
2. When drilling a large hole, first drill a pilot hole using
a smaller drill bit.
3. Always apply pressure to your drill bit in a straight
line, and if possible at right angles to the workpiece.
4. Never change the operating mode whilst the drill is
running.
5. 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.
ENVIRONMENTAL
PROTECTION
Waste electrical products must not be disposed
of with household waste. Please recycle where
facilities exist. Check with your local authorities
or retailer for recycling advice.

The following table gives checks and actions that you can perform if your machine does not operate correctly.
