Adjustingthe Depth Of Cut; Feed Rate Adjustment; V-Belt Adjustment - Craftsman 351.233831 Operator's Manual

ADJUSTINGTHE DEPTH OF CUT
Refer to Figure 16, page 18.
Board thickness which the planer/molderwill produce is
indicated by either scale (Key No. 4) on the side.
Thickness is adjusted by rotating the handwheel (Key
No. 22) clockwise to raise the knife height.
To reduce the knife height, rotata the handwheel coun-
terclockwise.
• Do not set knife below %2". Do not plane a board
which is less than a 1,_,thick.
• Knife height will be moved 1Ae" w ith every complete
revolutionof the handwheel.
Make a test cut on a piece of wood and measure the
thickness produced.
The planer/molder will produce uneven depth of cut
(tapered cut) ifthe cutterhead is not parallel with the table.
To restore parallelism of the cutterhead with the table:
• Clamp a vise plier on the left side of the shaft (Key
No. 6) next to the bevel gear (Key. No. 10).
• Loosen set screws (Key No. 51) and disengage right
bevel gear (Key No. 10) on the elevation screw (Key
No. 18).
• Slowly rotate handwheel to raise or lower the table.
Rotate clockwise to raise table, counterclockwise to
lower table. Table will be moved by .004" with every
turn of the beveled gear by one tooth.
• After moving table the required distance, make sure
beveled gears (Key Nos. 10 and 12) are engaged
and secured with set screws.
• Release and remove the vise plier
• Make a test cut to make sure the adjustment was
appropriate.
• Add grease to bevel gears if necessary.
When the depth of cut adjustment is operating correctly,
loosen the pan head screw (Key. No. 28) and set the
indicator (Key No. 29) to show the thickness produced.
Make sure that the indicator is positionedcorrectly.
TABLE HEIGHT ADJUSTMENT
Refer to Figure 16, page 18.
• The depth of cut of the planer/molder is adjusted by
raising or lowering the table.
• Rotate the handwheel (Key No. 22) to raise or lower
the table to the desired position.
• The scale and indicator (Key Nos. 4 and 29) can be
used when adjusting the table height.
FEED RATE ADJUSTMENT
Refer to Figures 5 and 15, pages 6 and 16.
The planer/molder has a 2-speed gearbox that feeds
the workplace at 13 feet per minute (FPM) for improved
surface finish when molding or planing and 26 FPM for
fester planing.
• Be sure to unplugthe planer/mctderfrom powersource
and turnplaner/molderOFF beforeadjusting the feed
rate.
Remove the socket head bolt (Figure 15, Key No.
33) that secures the gearbox cover (Figure 15, Key
No. 35), remove the gearbox cover. See Figure 5 for
the proper location of the gears.

26 FPM
- 30T
-_i]
The planer/molder is assembled with the gears for 13
FPM. Both planing and molding can be done at this set-
up. For the increased feed rate -- 26 FPM, the gears
have to be changed. Gears for 26 FPM are in the hard-
ware bag.
To change gears:
• Loosen and remove nylon insert Iocknutsi(Figure 15,
Key No. 28).
• Slide two screwdrivers, one on either side of the 40T
molding gear (Figure 15, Key No. 31).
• Gently push the screwdriversand slide g_ar off the
gear shaft (Figure 15, Key No. 29).
• Leave the key (Figure15, KeyNo. 27) in the gear shaft.
• Remove the 21T moldinggear (Figure 15, Key No. 26).
• Positionthe gears for 26 FPM on the gea'rshaft,
aligningthe keyway.
• Gently push it into place.
• Replace and tighten nylon insert Iocknuts
V-BELT ADJUSTMENT
Refer to Figures 14, 15 and 16, pages 14, 16 and 18.
Inadequate tension in the V-Belt (Figure 15, Key No. 54)
will cause the belt to slip from the motor pulley (Figure
14, Key No. 9) or ddve pulley (Figure 15, Key No. 53).
To adjust V-Belt tension:
• Loosen and remove four socket head bolts (Figure
16, Key No. 5) on cover (Figure 16, Key No. 2)
• Remove cover.
• Loosen two sockethead bolts (Figure 16, ,Key No. 48)
thatgo through the tensionplate (Figure16,gay No.39).
• Tighten two sockethead bolts (Figure 16, Key No.
48) that go intothe indent on tension plate to tension
belt. Belt is tensioned properlywhen moderate finger
pressure applied to the midpointof belt produces _"
deflection.
• Tighten two sockethead bolts (Figure 16, Key No. 48)
that go throughthe tensionplate.
• Replace cover and tighten four bolts (Figure 16, Key
Nos. 2 and 5).
