Adjusting the Conveyor
Belt Tension
Check and adjust the belt tension frequently
52). All rubber conveyor belts stretch, especially when
they are new or have not been used for a while.
1.
Park the machine on level ground with the rear
gate and feed gate at least 6.25 mm (1/4 inch)
off the floor (depending on the material).
2.
Fully load the machine with sand that you expect
the machine to use.
3.
Remove the black front covers on either side of
the machine.
4.
Using two wrenches, hold the end of the
tensioner rod stationary, while loosening the
locking nut closest to the end of the rod.
5.
Move the locking nut back 2 to 5 cm (1 to 2
inches).

WARNING
Operating the conveyor belt with the
guards and covers removed can cause
serious injury.
Use extreme caution around moving
parts with safety guards removed.
6.
Turn on the conveyor belt.
7.
If belt slips, tighten the tension bolts evenly
(with machine off) half a turn and check if the
belt slips again. Continue until the belt moves
without any slippage.
8.
Give both tensioning bolts another half turn. At
this point you should have proper tension.
9.
To verify belt tension, look underneath the
machine at the chassis cross member. The
middle of the belt should just clear the chassis
cross member when the machine is in the down
g014129
position. If the middle of the belt is touching
the cross member, tighten both tensioning bolts
another quarter of a turn.

Changing the Conveyor
Belt
Read these instructions before removing the belt. If
the belt is destroyed, use a knife to cut the belt in an
undamaged area. If you intend to make a warranty
claim, the belt supplier must inspect the belt to
evaluate the damage and make recommendations
for a replacement.
Removing the Belt
1.
Remove the black safety covers located on the
four outer corners of the machine.
2.
Remove the guides for the inner rubber liner
from the front and both sides of the hopper, with
the metal rails attached.
3.
Remove the silicone sealer on the rear of the
metal rails (but remember to apply the silicone
sealer when re installing them).
4.
At both front corners, use two wrenches to hold
the end of the tensioner rod stationary.
5.
Loosen the nut closest to the end of the
tensioning rod.
6.
Move the inside adjusting nut back until the
tensioning rod clears the pillow block bearing.
