Leadscrews
– (refer to Figure 4-1). Clean both
leadscrews with a brush and/or soft rag. Apply
a light coat of #2 lithium tube grease along the
entire length of both leadscrews.
Columns
– (refer to Figure 4-1). Clean all four
columns with a soft rag. Apply a light coat of #2
lithium tube grease to the columns. Wipe away
excess grease.
Drive chain
– Remove left side cover (refer to
sect. 10.8
on removing side cover). Remove
chain guard. Clean any debris from the chain
and sprockets, and apply standard wheel
bearing grease to the chain. Keep the chain
clean of dust, dirt, and wood shavings. Do not
over-lubricate. Over-lubricating the chain will
attract contaminates and increase wear on the
chain.

Head elevating chain
– Carefully tilt planer
onto its left side, as shown in Figure 10-3.
(Make sure side covers are installed before
tilting planer.) Clean any debris from the
underside of the machine and from the chain
and sprockets. Apply standard wheel bearing
grease to the chain. Turn the crank handle a few
times to spread the grease, then wipe off any
excess.

Thickness scale calibration
If the thickness scale becomes inaccurate after
extended use, plane a board and carefully measure
its thickness. If the scale does not match this
measurement, loosen the two screws on the cursor
(see Figure 4-1) and adjust the cursor as needed.
Retighten screws.
10.6
Belt replacement
Inadequate tension on the V-belt will cause the belt
to slip from the motor pulley or the cutterhead pulley.
A loose belt must be replaced, as follows.
1. Disconnect planer from power source; unplug.
2. Remove crank handle.
3. Unscrew the two screws on the right side of the
top plate (A, Figure 10-4) with a 5mm hex
wrench; a T-handle wrench is preferred for this.
The screws do not need to be removed, only
released from the tops of the columns.
4. Carefully maneuver the right side cover from
beneath the top plate, and lift side cover out of
the groove in the planer base.

5. Remove two screws (B, Figure 10-5) with
Phillips screwdriver, and remove belt guard (C).
