8. Operation
a) Start drilling
• Startthetoolbysqueezingthevariablespeedtriggerswitch.Releasethetriggertostopthetool.
• If you press the lock on button while the trigger switch is depressed, the switch is kept in the operating position. This
is convenient when continuous operating for extended periods of time is required.
• To release the lock on button, press and release the trigger switch .
b) Hole drilling
When attempting to drill a large diameter hole, it is sometimes best to start with a smaller drill bit then work
up to the required size. This prevents overloading the drill.

out a small hole may cause the drill bit to jam in the hole, especially when drilling metal.

bit snags, switch off immediately to prevent permanent damage to the drill.
• Try running the drill in reverse to remove the bit.
• Keep the drill in line with the hole. Ideally, the drill bit should enter at right angles to the work. If the angle is changed
during drilling, this could cause the bit to snap off blocking the hole and perhaps causing injury.

own pace.
• Keep the drill bit sharp.
c) Drilling wood
• For maximum performance when drilling larger holes, use auger bits or spade bits for wood drilling. Set the tool to
the drill mode.
• Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed as it bites
into the wood.
• When drilling through holes, place a block of wood behind the work piece to prevent ragged or splintered edges
on the back of the hole.
d) Drilling metal
• For maximum performance, use HSS drill bits for metal drilling. Set the tool to the drill mode.
• Mark off the centre of the hole using a centre punch.
• Use a suitable lubricant for the material you are working on.
• Begin drilling at a very low speed to prevent the bit from slipping off the starting point. always clamp sheet metal.
Support thin metal with a block of wood to avoid distorting it.
