Setting up a new belt
Tracking the belt
It is necessary that the belt is properly balanced and set to run in its accurate
position, to assure maximum reliability and performance of the machine. It is
important to balance the belt so that it stays well centred on the pulleys, in
both directions of operation.
×8 18mm
CONTROLS AND PROCEDURE
Plug in the chassis/frame unit to power
mains.
• Switch the satellite motor on at low
speed. Increase the speed as you find
the balance.
1. Skew the pulleys to control the belt
position:
• Fit a suitable screw driver in the last
exterior bolt hole.
• With belt running; apply enough pres-
sure to lightly skew the bottom plate
with the pulleys. This will control the
belt tracking; up, down or ultimately
in the accurate position.
2. Check the position of the belt:
(a) Too low: Adjust the skew so the
belt runs higher on the pulleys.
(b) Accurate: This position assures
maximum contact area over the
pulleys and minimum wear of the
belt – in both directions.
(c) Too high: Adjust the skew so the
belt runs lower on the pulleys.
3. Use air gun to tighten the most dis-
tant exterior bolt (with reference to the
screw driver).
4. Use the direction switch, to reverse the
belt rotation after tightening the bolt.
• Repeat step 1—4 above until eight ex-
terior bolts are tightened, and the belt
stays running in its accurate position.
Tighten each bolt in the manner de-
scribed in picture 5.
5. Here tightening a bolt, while tracking
the belt by maintaining proper skew
with the screw driver.
Be sure to change the direction
of the belt after each bolt is
tightened!
FINAL CHECKS
6. Verify that the belt setup is correct and
that the belt runs accurately balanced.
• As a last measure, the distance between
belt and the top of the plate should be
28mm +/-2mm. However, the float in
the belt between directions should nev-
er exceed a total of 2mm.
7. Recondition the internal threads of the
9 th exterior bolt hole, using an M12 tap
and a T-wrench.
