5.1.2 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 Tightening 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 Tightening torque wrench (C) to
tighten the saw belt until the Tightening 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 Tightening torque wrench (C) to
properly tighten the saw belt.
The tips of the saw belt teeth
are hardened and cannot be re-
sharpened.
5.2 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)
Fig. 5:
Saw belt guide
Worn carbide metal plate (a) (groove marks)
can be turned (all 4 sides can be used).
Turning the plate early prevents cracks on the
back of the saw belt.
The carbide metal rods (b) cannot be adjusted.
They may be turned to make best use of the
entire circumference at the top and bottom
ends. Replace worn rods. This is to prevent
cracking and to warrant correct sawing results.
Check that the saw belt guide can move freely.
Regularly check the fibre guide (d) for wear
and replace as necessary.
