Inspect the V-belts closely; if you notice fraying,
cracking, glazing, or any other damage, replace
the belts. A worn or damaged V-belt will not pro-
vide optimum power transmission from the motor
to the drum and feed belt.
V-belt removal and replacement is simply a mat-
ter of loosening the V-belts, rolling them off of
the pulleys, replacing them with new belts, then
retensioning them.
Tools Needed: Qty
Wrench or Socket 19mm ................................... 1
To replace the V-belts:
1. DISCONNECT JOINTER FROM POWER
SOURCE!
2. Open the pulley cover.
3. Loosen the fasteners on the tension rod that
hold the motor to the bracket ( Figure 61).

4. Lift the motor up and slide the V-belts off of
the motor pulley and cutterhead pulley.
5. Slide the new belts onto the pulleys, tighten
the motor bracket fasteners, and close the
pulley cover.
Pulley Alignment
Pulley alignment is another important factor in
power transmission and belt life. The pulleys
should be parallel to each other and in the same
plane (coplaner) for optimum performance.
Each pulley can be adjusted by loosening the
motor mount fasteners, sliding the motor in or out,
and retightening the fasteners to lock the motor
pulley in place.

Wrench or Socket 17mm ................................... 1
To align the pulleys:
1. DISCONNECT JOINTER FROM POWER
SOURCE!
2. Open the pulley cover.
3. Visually check the alignment of the two pul-
leys to make sure that they are aligned and
that the V-belts are straight up and down (see
Figure 62).
— If the pulleys are aligned, tighten the motor
mounts and go to Step 8.
— If the pulleys are NOT aligned, do Steps 4
& 5.
