4.5 Support of the workpieces:
Ensure that your workpieces are securely fixed and cannot
move during sawing. Otherwise, there is an increased risk of
accident. Never hold the workpiece to be cut with your hands
or between your legs. Use instead screw clamps (12.1) or
some other suitable devices to fix your workpiece.
Never position large or long workpieces so that they bend in
the middle or at the cutting face. This can lead to the saw
blade jamming and recoiling. Instead, support the workpiece
with several wooden battens (12.2), particularly in the vicinity
of the cutting face.
Sawing aluminium:
When sawing aluminium, the following measures
must be taken for safety reasons:
- Pre-connect a residual current circuit-breaker.
- Connect the machine to a suitable dust extractor.
- Clean the machine regularly of dust deposits in the motor
housing and in the protective cover.
- Wear protective goggles.
- Aluminium must only be sawed with the special saw blades
from Festool designed for this purpose.
- When sawing panels, they must be lubricated with petroleum,
thin-walled profiles (up to 3 mm) can be sawed without
lubrication.
5 Servicing and maintenance
Any maintenance or repair work that requires
opening of the motor or gear housing should only be carried
out by an authorised Customer Service Centre (name supplied
by your dealer)! Maintenance or repair work carried out by
an unauthorised person can lead to the wrong connection of
the power leads or other components, which in turn can lead
to accidents with serious consequences.
To prevent accidents, always remove the plug
from the power supply socket before carrying out any
maintenance or repair work on the machine! Do not use
compressed air to clean the electrical tool! Do not try to clean
parts inside the machine in this way, as you could let foreign
objects in through the openings of the machine housing.
Certain cleaning agents and solvents are harmful
to plastic parts. Some of these are: gasoline, carbonyl
chloride, cleaning solutions containing chlorine, ammonia and
household cleaners containing ammonia.
To assure the circulation of air, the cool air vents in the motor
housing must always be kept clear and clean.
This unit is fitted with special, automatically disconnecting
carbon brushes. If these become worn, the current is
automatically switched off and the unit shuts down. In this
case, take the unit to an authorised Customer Service Centre
and have the carbon brushes changed.
After being removed away from the workpiece, the machine
automatically returns to its basic position, the saw blade
retracts into the protective cover and the cut-in and release
block engages once again. If this no longer functions, stop
using the hand-operated circular saw and have it repaired
immediately by an authorised Customer Service Centre.
The riving knife must be aligned with the saw blade, and should
not be crooked. A faulty riving knife must be replaced
immediately. Under no circumstances use the saw without
the riving knife because of the increased risk of recoil.
Even with proper usage the teeth of the saw blade become
blunt in time. Change the saw blade as soon as you notice
that you need a greater force to push the machine during
