BRUSH INSPECTION
AND REPLACEMENT
CAUTION: BEFORE INSPECTING THE BRUSHES, DIS-
CONNECT THE TOOL FROM THE 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. 26,
are located on the motor housing opposite each other.
Fig. 27, illustrates one of the brushes removed for in-
spection. 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.
LUBRICATION
The gears in the gear box and the feed roller bushings
should be lubricated periodically, as follows:
1. DISCONNECT THE TOOL FROM THE POWER
SOURCE.
2. Remove screw (A) Fig. 28, and nut located on the
other end of screw. Remove the side cover (B) from the
left side of the planer.
3. Place a light coat of E.P. multi-purpose grease on
the teeth of the large gear (C) Fig. 29, and a light coat of
spray lubricant to chains (F). Replace the side cover.
4. Lay the planer on its back and squirt oil on the feed
roller bushings (D) Fig. 30, at each end of the feed rolls (E).
