work!
Assembly work may only be
carried out by authorised
specialist personnel.
Only use original EFA spare
parts!
4.1 Replacing the saw belt
The saw belt to be replaced
only if the units are
disconnected from the
mains!
Never reach into the area of
the moving saw belt. Risk
of cutting off extremities!
4.1.1 Disassembling the saw belt
Open both lids (A) by their flaps (B)
(each lid has its own magnetic
catch).
Loosen the saw belt by turning the
torque wrench (C) anti-clockwise.
This will slacken the saw belt.
Lift guiding implement and lever (D),
push saw belt out of the guides and
take belt off the wheels (see section
"Saw belt guide").

4.1.2 Assembling the saw belt
Smoothly fit the saw belt over the
wheels, teeth against the housing;
the teeth must face the motor.
Check that the teeth fit into the
recessed diameter of the wheels to
produce grip (free-wheeling see
next figure).
Use the torque wrench (C) to slightly
tighten the saw belt.
Push up guide and lever (D),
manually turn up the saw and thread
belt into the guides.
Release the lever (D) (automatically
snaps into working position)
Use the torque wrench (C) to tighten
the saw belt until the torque wrench
snaps in (wrench quietly clicks).
Briefly turn on the machine to allow
the saw belt to automatically adjust
its position on the wheels.
Use the torque wrench (C) to
properly tighten the saw belt.
The tips of the saw belt
teeth are hardened and
cannot be re-sharpened.
4.2 Saw belt guides
The belt saws feature two identical
saw belt guides which, as major belt
saw components, need to be
cleaned and checked daily and
replaced in due time when worn out.
The saw belt guides provide the
following functions (see next
figure):
Carbide metal plate (a) - absorbs
the sawing pressure
2 Carbide metal rods (b) - deflect
and guide the saw belt
Pressure spring (c) - spring-actuated
absorber of the sawing pressure
Fibre guide (d)
