9.2 ADJUSTING BELT TRACKING –
FIGS.9 - 10
The purpose of belt tracking is to make sure the
belt stays centered on the wheels and platen
during grinding operations. It needs to be checked
any time you change or replace the belt.
Warning! Never attempt to adjust, maintain or
service this machine while it is connected to the
power supply.
To check and adjust the belt tracking:
– Open the belt access panel.
– Standing at the rear of the machine, rotate the
drive wheel
(13)
with one hand and watch how
the belt tracks:
- If the belt moves towards the motor (or the
front of the machine) rotate the tracking knob
(5)
clockwise.
- If the belt moves away from the motor (or
towards the back of the machine) rotate the
tracking knob
(5)
anti-clockwise.
– Repeat the test after adjustment to make sure it
is now tracking centrally. Once central close the
belt access panel
(9)
.
– Connect the machine to the power source and
turn it ON. Visually check that the belt is
tracking correctly in the centre of the platen
and wheels, and fine-tune any tracking as
necessary.
