Replacing the Poly V-Belt
Disconnect machine from
power source before making any adjustments.
1. Place
the
mode selection lever
(J, Fig. 18) in
the
Full Release
position.
Referring to Figure 25:
2. Loosen the
lock handle
(A) that secures the
motor
(C).
3. Release belt tension by pulling
handle
(B) up
which raises the motor, then tighten
lock
handle
(A).
4. Open the lower wheel
door
(C, Fig. 27) and
remove the
hex nut
and
washer
(D, Fig. 27).
5. Remove the
wheel
(E, Fig. 28). If the lower
wheel does not come off easily you may need
to use a pulley puller to remove it.
Note:
If you are doing a pulley alignment
only
, skip
Step 6.
6. Remove
the
old
belt
(F, Fig. 28) and install the
new belt.
Note:
For
higher blade-speed
, place the belt on
the pulleys closest to the motor (A, Fig. 26). For
lower blade-speed
, place the belt on the
pulleys away from the motor (B, Fig. 26).
Since the wheel is still off, this is the most
convenient time to check the wheel and motor
pulley alignment. Jump to the
Pulley Alignment
procedure (following page) at this time. At the
conclusion you will be redirected back here.
After the pulley alignment (if performed) is
complete:
7. Reinstall the lower wheel, hex nut and washer
and tighten the hex nut.
8. Unlock
lock handle
(A, Fig. 25). Apply belt
tension by slightly pushing
handle
(B, Fig. 25)
down.
9. Tighten
the
lock handle
(A, Fig, 25) to secure
the
motor
(C).
