Lubrication; Motor Brushes - Grizzly G0505 Owner's Manual

Lubrication

There are two primary assemblies that require
lubrication—the cutterhead elevation leadscrews
and the feed roller chain drive. The bearings of the
motor and cutterhead are factory lubricated and
sealed, and require no other attention unless they
need to be replaced.
Tools Needed
Phillips Screwdriver ........................................... 1
Hex Wrench 5mm .............................................. 1
To lubricate the planer:
1. DISCONNECT PLANER FROM POWER!
2. Remove the elevation crank, the top cover,
both side panels, and the inner cover, as
shown in Figure 25.
Chain Drive

exposed for lubrication.
3. Vacuum chips and dust from the leadscrews,
chain drive, and the surrounding areas, use a
brush and mineral spirits to remove any built-
up grime, then use clean shop rags to dry the
parts.
4.
Brush a light coat of general purpose grease
onto both leadscrews.
5.
Spray a moderate amount of chain oil onto
the chain drive and the cogs, then wipe off
the excess with a clean rag.
6. Re-assemble the sides and top cover, then
move the cutterhead up and down to distrib-
ute the lubricant on the leadscrews.

Motor Brushes

The motor is equipped with two long-life carbon
brushes. The brush life is affected by motor loads
and usage. If either brush is worn down to
(6mm) or less, replace both brushes as a set.
Tools Needed
Standard Screwdriver ........................................ 1
To check/replace the motor brushes:
1.
DISCONNECT PLANER FROM POWER!
2.
Unscrew the plastic cover, and remove the
front motor brush assembly, as shown in
Figure 26.
Note: As you remove the brush assembly,
make note of the orientation of the carbon tip
so that, if found acceptable, you can re-install
it the same way.

3. Measure the length of the carbon tip.
— If the carbon tip is worn down to
or less, replace both brush assemblies with
new ones.
4. Repeat Steps 2–3 with the motor brush found
on the right, rear of the motor.
5. After inserting the brush assemblies back into
the motor, re-install the plastic caps to hold
them in place.
