Tensioning/Replacing
V-Belts
To ensure optimum power transmission from the motor to
the cutterhead, the V-belt must be in good condition (free
from cracks, fraying and wear) and properly tensioned. As
the machine is used over time, the belts will slightly wear
and stretch, eventually losing their efficiency of transmit-
ting power, until they can be re-tensioned.
Also, new belts typically have a break-in period and should
be checked/re-tensioned after the first 16 hours of belt
life, as it will stretch and seat during this time.

Replacing V-Belt
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove cabinet rear access panel, and loosen motor
mount bracket fasteners shown in
Figure
74
.
3.
Have another person lift motor as you remove V-belt
and replace it with a new one. Make sure V-belt is
seated in pulley.
4.
Follow
Steps 4–5
in
Tensioning V-Belt
on this page to
set correct belt tension, then tighten motor mount
bracket fasteners (see
Figure 74
), and replace cabi-
net rear access panel.
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove cabinet rear access panel, and loosen motor
mount bracket fasteners shown in
Figure 74
.
Note:
DO NOT completely remove motor mount
bracket fasteners.
4.
Press down on motor to keep tension on belt.
5.
Press belt with moderate pressure in center to check
belt tension. Belt is correctly tensioned when there is
approximately
1
⁄
2
" deflection when pushed, as shown
in
Figure 75
.
— If there is more than
1
⁄
2
" deflection when you check
belt tension, repeat the tensioning procedure until
it is correct.
6.
Tighten motor mount bracket fasteners (see
Figure
74
), and replace cabinet rear access panel.
