GENERAL SAFETY PRECAUTIONS
1.
Keep your Clarke Cordless drill and all other power tools out of reach of children.
2.
Keep all equipment dry especially the battery and battery charger.
3.
When drilling into walls, ceilings and floors, check first for concealed main
services, Water, Electric and Gas.
4.
Always wear safety goggles*. Take particular care when drilling overhead.
5.
We recommend the use of an appropriate dust mask*.
6.
Loose clothing and long hair can prove a danger if caught up in machinery.
Take suitable precautions.
7.
When drilling into certain materials, sound pressure levels may prove a
discomfort, in which case we recommend the use of ear defenders*.
8.
ALWAYS disconnect from the mains supply when changing bits or when the
drill is not required for immediate use..
9.
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 prepaired for it.
10. DO NOT use in damp or wet conditions. Keep the work area well lit. DO NOT use
where a risk of fire or expolosion is present.
11. ALWAYS 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
dealer for information on the various Clarke safety products
available.
HELPFUL HINTS 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 lubriant when drilling all metals except brass and cast
iron which should be drilled dry.
•
As a general rule, when drilling metal, the harder the metal the slower the drill
speed. Similarly, the bigger the drill the slower the speed. Consult a suitable
book of referrence if necessary.
Always start drilling at a slow speed to prevent the drill from slipping out of the
pop mark or indent, gradually increasing speed until the optimum cutting speed
is achieved whilst maintaining a MODERATE pressure ONLY. NEVER forcethe drill
bit into the work. This will overheat the tip and cause it to dull very quickly.
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.
