operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc.,
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for operations
different from those intended could result in a hazardous
situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.

BEFORE USE
• Always check that the supply voltage is the same as
the voltage indicated on the nameplate of the tool (tools
with a rating of 230V or 240V can also be connected to
a 220V supply)
• Avoid damage that can be caused by screws, nails and
other elements in your workpiece; remove them before
you start working
• Use completely unrolled and safe extension cords with a
capacity of 16 Amps (U.K. 13 Amps)
• The noise level when working can exceed 85 dB(A);
wear ear protection
• Dust from material such as paint containing lead, some

with additives for wood conditioning; wear a dust
mask and work with a dust extraction device when
connectable
• Follow the dust-related national requirements for the
materials you want to work with
• Wear protective gloves, safety glasses, close-fitting
clothes and hair protection (for long hair)
• Secure the workpiece (a workpiece clamped with
clamping devices or in a vice is held more securely than
by hand)

use dustbag and keep other persons and combustible
material from work area
DURING USE
