GENERAL SAFETY PRECAUTIONS
Before plugging into the mains supply, ALWA YS fit the appr opriate drill bit first, then
pull the trigger briefly and release, to ensure the drill is not locked in the ON
position. If you change a drill bit, ALWA YS disconnect from the mains beforehand.
To Switch ON:
Pull Trigger ‘A’
Continuous Operation:
Pull Trigger ‘A’ and lock by pressing
button ‘B’
NOTE: The speed is varied by applying
more or less pressure on switch A. The
maximum speed may be pre-selected
by turning the knurled knob C, within
switch A.
To switch OFF:
Pull Trigger ‘A’ briefly and then release.
Forward/Reverse Selection
Push the slide lever ‘D’ fully to left for normal rotation.
Push the slide lever ‘D’ fully to right for reverse rotation.
Hammer Selection
• Keep your Clarke drill and all other power tools out of reach of children.
• Keep the drill dry - do not use near water, steam or flammable liquids.
• When drilling into walls, ceilings and floors, check first for concealed services,
i.e. Water, Electric and Gas.
• Always wear safety goggles**. Take particular care when drilling overhead.
• We recommend the use of an appropriate dust mask**.
• Loose clothing and long hair can prove a danger if caught up in machinery.
Take suitable precautions.
• The level of noise may exceed 85 dB(A) when hammer drilling into concrete/
masonry etc., in which case we strongly recommend the use of ear defenders**.
• Always disconnect from the mains supply when changing bits and for all
adjustments and maintenance work.
• Always protect the mains cable, be aware of your surroundings. Do not allow
the cable to rest on hot surfaces, sharp edges, in oil or acids etc.
• When using an extension cable, ensure it is completely unwound from the drum.
• NEVER carry the drill by the cable.
• NEVER pull on the mains cable to disconnect from the mains supply.
• Always make sure you have a firm and secure stance when using the drill
particularly when on a ladder or scaffold.
• ALWAYS hold the drill firmly with BOTH hands when drilling. A drill could stall if
overloaded or used improperly. ALWAYS expect a stall and be prepared for it.
•
ALWA YS ensure the workpiece is perfectly secure before drilling. Use clamps or
a vice which is safer than your hands and frees both hands to operate the drill.
• Contact your CLARKE dealer for information regarding the various safety
products available.
Slide the switch, on top of the drill, to the ‘Hammer’ position ~ denoted by a
hammer symbol.
For normal drilling the switch should be in the ‘Drill’ position, denoted by a drill bit
symbol (particularly when drilling tiles, ceramics etc.).
DO NOT operate this switch until the drill has stopped.

GENERAL ADVICE ON DRILLING
• After drilling material to the full depth, do not simply pull out the drill but maintain
chuck rotation to ease withdrawal.
• Keep drill bits sharpened for optimum performance.
• Always drill directly in line with the bit. Do not use sideways movement as this
may damage the drill or cause the bit to break.
• Always use a cutting lubricant when drilling all metals except brass and cast
iron which should be drilled dry.
•
If the drill is not cutting the metal then sharpen the drill, ensuring the various cutting
angles are correct. Consult a suitable book of reference or a qualified technician.
