Hammer action without rotation (for chiselling concrete, wood, etc.)
Push in the function selector lock and turn it all the way to the left so the arrow points
to the
symbol.
In order to adjust the accessory to the desired position, the function selector should
be set to the
symbol.
Useful tips
• When using the hammer only mode, you should apply light pressure to the drill.
The application of too much pressure can reduce the hammer effect. Try applying
different amounts of pressure until you find the most effective one.
• Check the condition of the drill bit/accessory regularly. Replace any worn drill
bits/accessories.
• Let the motor run for a few minutes under no load after hard use to let it cool down.
• For hard metals use titanium coated drill bits and for concrete/tiles use tungsten
carbide tipped bits.
• Fasten the workpiece down securely if possible. Use clamps or vices when you
can, this will leave you with both hands free to manoeuvre the machine with,
which increases precision.
• If you are drilling into thin materials it is important that you place a small piece of waste
material behind the hole to be drilled, otherwise there is a risk of burring on the back.
• Hold the rotary hammer drill perpendicular to the workpiece before starting to drill
(look from several angles). Make sure that you keep the drill straight, do not force
the drill out of line when drilling.
• Do not apply so much pressure that the drill reduces speed. Let the drill bit/chisel
do the work. Reduce pressure before the drill breaks through the material.
• Let the drill bit continue to rotate once it has broken through the material, this
allows the motor to cool down and also clears the drill bit from debris.
Things to consider when drilling into wood and plastic
• For wood and other soft materials there are several types of accessories such as
hole saws, flat wood bits, etc. Select the most suitable tool for the job. Test the drill
on a piece of waste material first.
• Drills can overheat if you don’t pull them up out of the hole often to free them
of sawdust.
• Place a small piece of waste material behind the hole to be drilled before starting to
drill otherwise there is a risk of burring around the edges of the hole on the back.
Things to consider when drilling into metal
• Mark where the hole is to be drilled using a centre punch.
• The drill bit can overheat if you use too high a speed. Use a cooling fluid suitable
for your workpiece material e.g. methylated spirit for aluminium. (Cast iron and
brass do not require cooling fluid).
