MAINTENANCE (CONTINUED)
NOTE:
Magnets can be easily disengaged from blade by tilting
them to left or right.
CAUTION:
Blade edges are extremely sharp. Keep fingers away
from blades at all times.
•
Reverse blade or replace with new blade and carefully position
it on the two setting rings using the two magnets. The setting
rings position the blade at the correct height. There is one set-
ting ring at each end of the cutterhead.
•
Secure blade by tightening the seven gib bolts. Make sure blade
does not move while tightening the bolts. Use a piece of scrap
wood to hold blade in place so it does not creep up. Tighten
bolts equally so that clamping force is uniform across blade.
•
Depress latch to release cutterhead. Release latch when cutter-
head can be turned by hand.
•
Turn cutterhead by hand until it is stopped by self-engaging latch.
•
Repeat the above procedure for the other blade.
•
Replace blade cover and secure it using screw.
ADJUSTING ROLLERCASE LEVEL
Refer to Figure 33.
The planer/molder will produce an uneven depth of cut (tapered
cut) if rollercase is not parallel with base. To restore parallelism of
rollercase with base:
•
Using a test piece, measure height of the taper. Determine
which corner or side needs adjustment.
•
Turn planer/molder off and disconnect from power source.
•
Fold front and rear extension tables.
•
Lay planer/molder carefully on its back so that bottom side of
base is facing you.
•
Loosen two socket head bolts on the idler bracket. Loosen
chain by sliding idler bracket.
•
Carefully rotate the sprocket by hand to change the rollercase
height. Be sure to leave the other sprockets untouched. Do not
rotate sprocket more than one or two teeth. Movement of one
sprocket tooth relative to the chain moves the rollercase
approximately 0.006
″
.
•
Retighten chain by securing idler bracket in position. Tighten
socket head bolts securely.
•
Set planer/molder back on its base.
•
Make a test cut to verify adjustment.
BRUSH INSPECTION AND REPLACEMENT
Refer to Figure 36, page 20.
WARNING:
Turn planer/molder off and disconnect from power
source.
•
Brush life depends on amount of load on motor. Regularly
inspect brushes after 100 hours of use.
•
Loosen brush cap and gently remove brush from motor (Ref.
Nos. 36 and 37). Be careful of springs.
NOTE:
Brushes are located on both front and rear of planer/molder.
•
Replace brushes if spring is damaged.
•
Replace brushes if carbon is worn to
1
/
4
″
length.
•
After inspection replace brush and cap.
REPLACING DRIVE BELT
Refer to Figures 35 and 37, pages 18 and 22.
Inadequate tension will cause drive belts to slip from the pulleys.
Loose belts must be replaced. To replace drive-belts:
•
Remove socket head bolt, plug and handle (Fig. 35, Ref. Nos. 4, 5
and 6). Pull knob (Fig. 35, Ref. No. 50) off.
•
Remove two flat head screws (Fig. 35, Ref. No. 7) from cap (Fig.
35, Ref. No. 8). Loosen cap. Remove right side cover (Fig. 35, Ref.
No. 49).
•
Remove fan belt (Fig. 37, Ref. No. 28) by walking the belt from
both pulleys alternately. Gently pull the belt while turning the
pulleys at the same time. Repeat with drive-belt (Fig. 37, Ref. No.
67).
•
Replace with new belt. Walk the belt onto the pulleys in the
reverse manner as when removing the belts.
•
Make sure the belt is evenly seated all the way on both pulleys.
•
Replace right side cover and knob. Replace cap and secure with
flat head screws. Replace handle and secure with plug and
socket head bolt.
