Changing drill and screwdriver bits
The drill/driver has a keyless chuck which enables drill or screwdriver bits to be changed
with one hand. Twist the chuck to the left to tighten, to the right to untighten. Make sure
that the bit is tight and centred in the chuck.
Overload protection and other safety features
The drill/driver and battery have a number of safety features that prevent damage to
the drill/driver and battery during use.
• During short high-load situations the overload protection may turn off the drill/driver
and battery. This protection resets automatically. Release the trigger, wait a few
seconds, ensure that there is no load and restart the drill/driver. The drill/driver
should now function normally again.
• During high-load for extended periods the overheating protection may turn off
the drill/driver/battery. The protection resets itself but the drill/driver cannot be
restarted until it has returned to normal operating temperature. Let it cool before
attempting to use it again. Adverse temperatures can occur in direct sunlight and
should therefore be avoided.
• The battery has a low-voltage protection which operates when the battery
becomes discharged. The low-voltage protection turns off the drill/driver
automatically and the battery then needs to be recharged.
Drilling tips and advice
• When drilling into slippery materials, like tiles, you should place a strong piece of
tape on the area in which you wish to drill to prevent the bit from wandering.
• When drilling into metal you should first use a centre punch to make a small
indentation at the spot where you wish to drill. This indentation will help hold
the bit in place and prevents it from wandering when you drill.
• When drilling into metal you should also use cutting oil to assist in drilling and to
preserve the drill/driver and drill bit.
• Always use a clamp or vice to hold the workpiece.
• When drilling into walls, make sure not to damage water pipes, electricity cables
or gas pipes.
Care and cleaning
• Always keep the motor’s ventilation openings free of dust and debris.
• Clean the product using a lightly moistened cloth. Only use mild cleaning agents,
never solvents or corrosive chemicals.
• For long-term storage (months) the battery should first be fully charged.
