An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal working period.
Identify additional safety measures to protect
the operator from the effects of vibration such
as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.
Assembly
Mounting/Replacing the Saw Blade
Before any work on the machine itself, pull
the mains plug.
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching
the saw blade.
Only use saw blades that correspond with
the characteristic data given in the operat-
ing instructions.

Dust/Chip Extraction

Before any work on the machine itself, pull
the mains plug.
Mounting the Extraction Adapter
(see figure B)
Attach the extraction adapter 24 onto the saw-
dust ejector 16 until it latches. Secure the ex-
traction adapter 24 additionally with the screw
23.
A vacuum hose with a diameter of 35 mm can be
connected to the extraction adapter 24.
The extraction adapter may not be mounted
when no external dust extraction is con-
nected. Otherwise the extraction channel
can become clogged.
.
Do not connect a dust bag to the extraction
adapter. Otherwise the extraction system
can become clogged.
To ensure optimum extraction, the extraction
