Double Insulation

The tool is double insulated. This means that
all the external metal parts are electrically insulated
from the mains power supply. This is done by plac-
ing insulated barriers between the electrical and
mechanical components so as to make it unnec-
essary for the tool to be earthed. Note: Double
insulation does not take the place of normal safety
precautions when operating this tool. The insula-
tion system is for added protection against injury
resulting from a possible electrical insulation failure
within the tool.

Electrical Safety

Always check that the power supply corresponds
to the voltage on the rating plate.

Using an Extension Cable

An extension cable should not be used unless
absolutely necessary. Use of an improper exten-
sion cable could result in a risk of fire and electric
shock. If an extension cable must be used, use
only those that are approved by the country's elec-
trical authority. Make sure that the extension cable
is in good condition before using. Always use the
cable that is suitable for the power input of your
tool (see technical data on name plate). The mini-
mum conductor size is 1.5mm2.

Cutting Depth Adjustment (Fig. D)
To increase or decrease the depth of cut, loosen
the butterfly screw (3), move the base (4) to adjust
the depth, and tighten the screw to secure the
To prevent tool fault, the depth-of-cut adjustment
knob has been set to the optimal position at fac-
tory default.
Users may also set the knob to a desired position
at any time.
Instruction for Use
