Brush Inspection; Replacing V-Belt - Craftsman 351.811580 Operator's Manual

BRUSH INSPECTION AND REPLACEMENT
WARNING: Turn planer off and disconnect from power
source. Brush life depends on amount of load on motor.
Regularly inspect brushes after 100 hours of use.
Brushes are located on either side of planer motor.
• Loosen brush cap and carefully remove brush from
motor.
NOTE: Brushes are located on both front and rear
sides of planer.
• Replace brushes if spring is damaged.
• Replace brushes if carbon is worn.
• Replace brushes and tighten brush caps.

ADJUSTING TABLE LEVEL
Refer to Figures 12 and 13, pages 12 and 14.
The planer will produce uneven depth of cut (tapered
cut) if the rollercase (Fig. 13, Key No. 31 ) is not parallel
with the base (Fig. 12, Key No. 34). To restore paral-
lelism of the rollercase with the base:
• Using a test piece, measure the height of the taper.
• Turn planer off and disconnect from power source.
• Fold the front and rear extension tables.
• Lay planer carefully on it's side so that bottom side
of the base is exposed.
• Clamp vise plier (not supplied) on the left side of
shaft (Fig. 12, Key No. 52) next to the gear (Fig. 12,
Key No. 56).
• Remove screw (Fig. 12, Key No. 59) and disengage
right gear from the elevation screw gear (Fig. 12,
Key No. 56).
• Slowly rotate handle (Fig. 12, Key No. 27) to raise or
lower rollercase. Rollercase will move by 0.006" with
every turn of the gear by one tooth. Move rollercase
tot he required distance to offset the taper.
• Re-engage the right and elevation screw gear and
replace retaining ring to secure.
• Release and remove vise plier.
• Set the planer back on its base.
• Make a test cut to verify adjustment.
REPLACING V-BELT
Refer to Figures 12 and 13, pages 12 and 14.
Inadequate tension in the V-belt (Fig. 13, Key No. 53)
will cause the belt to slip from the motor pulley (Fig. 13,
Key No. 55) or drive pulley (Fig. 13, Key No. 52). Loose
belt must be replaced. To replace V-belt:
• Turn planer off and unplug from power source.
• Loosen and remove screws on right cap (Fig. 12,
Key No. 28). Remove panel (Fig. 12, Key No. 29).
• Loosen and remove screws (Fig. 13, Key No. 28) on
belt guard (Fig. 13, Key No. 27). Remove belt guard.
• Loosen bolt (Fig.13, Key No. 39) to loosen motor
assembly.
• Remove old belt by walking the belt from motor
and drive pulleys alternatively. Push motor down and
pull the belt outward while turning the pulleys at the
same time.
• Replace with new belt. Walk the belt on to the pul-
leys in the reverse manner as when removing the
belt.
• Make sure the belt is evenly seated all the way on
the motor and drive pulley grooves.
• Pry motor upward to apply tension to belt. Secure in
position by tightening bolt (Fig. 13, Key No. 39).
• Replace belt guard and screws (Fig. 13, Key Nos. 27
and 28).
• Replace and secure right panel.
LUBRICATION
• Motor and cutterhead bearings are sealed and need
no lubrication.
• Gears and elevation screws should be cleaned of
debris and greased as needed.
CLEAN PLANER
• Keep planer clean of any wood chips, dust, dirt or debris.
• After 10 hours of operation, the chains and gears
should have wood chips, dust and old grease
removed.
• Use common automotive bearing grease to lubricate
all chains and gears. Be sure all chains and gears
have plenty of grease.
• Clean the granite table using a soft, damp cloth. Do
not use any waxes, oils or solvents on the table.
