G0550/G0551 15" Planer
To ensure optimum power transmission from the
motor to the blade, the V-belts must be in good
condition (free from cracks, fraying and wear).
Check the V-belts at least every 3 months; more
often if the planer is used daily.
Make sure that the motor pulley and cutterhead
pulley are aligned and the V-Belts are properly
tensioned.
To align the V-Belt:
1. Disconnect the machine from the power
source!
2. Remove the V-Belt cover.
3. Loosen the bolts that mount the motor to the
motor mount bracket.
4. Adjust the position of the motor until the pul-
leys are in line, and check the alignment with
a straightedge as shown in Figure 19.

Figure 20. Tensioning Belt.
Squeeze the V-Belts at their midpoints with mod-
erate finger pressure. You should be able to
deflect each V-Belt about 3/4". Belts will rarely be
too tight, but will sometimes be too loose.
To tension the V-Belt:
1. Disconnect the machine from the power
source!
2. Insert a wooden lever between the motor
mount and the top of the planer as shown in
Figure 20.
Loosen These Bolts
3. Loosen the two bolts that hold the motor pul-
ley assembly to the planer (Figure 19).
4. Lift the motor assembly with the wooden
lever until the belt is tensioned correctly.
5. Hold the motor in place and secure the bolts
loosened in step 3.
6. Squeeze the belts to check the tension and
repeat steps 2-5 if necessary.
