BRUSH INSPECTION AND
REPLACEMENT
Disconnect tool from power source
Brush life varies. It depends on the load on the motor.
Check the brushes after the first 50 hours of use for a
new machine or after a new set of brushes has been
installed. After the first check, examine them after about
10 hours of use until such time that replacement is
necessary.
The brush holders, one of which is shown at (A) Fig. 27,
are located on the motor housing opposite each other.
One of the brushes, removed for inspection, is illustrated
in Fig. 28. When the carbon (B) on either brush is worn
to 3/16" in length or if either spring (C) or shunt wire is
burned or damaged in any way, replace both brushes.
If the brushes are found serviceable after removing, re-
install them in the same position as removed.
After brush maintenance is
completed, the cutterhead guard must be re-installed
before starting the planer.
LUBRICATION
The gears in the gear box and the feed roller bushings
should be lubricated periodically.
Disconnect tool from power source.
1. Remove the screw (A) Fig. 29, and nut located on the
other end of screw. Remove the side cover (B) from
the left side of the planer.
2. Place a light coat of E.P. multi-purpose grease on
the teeth of the gears (C) Fig. 30, and a light coat
of spray lubricant on the chains (F). Replace the side
cover.
3. Place the planer on its back and squirt oil on the feed
roller bushings (D) Fig. 31 at each end of the feed
rollers (E).
