Belt Tracking; Replacing Belt - Craftsman 351.226060 Operator's Manual

HORIZONTAL BELT SANDING
Refer to Figures 9 and lt.
• Adjust the belt housing to full horizontal position as
described in the above section, "Adjusting Belt Housing".
• Remove the belt table by removing handle(Key No. 16).
• Install work stop as described in "Work Stop", page 6,
Figure g - Horizontal Belt Sending
• Idler drum (Key No, 65) can be used as a contact drum to
sand curved surfaces.
ABRASIVE BELT FINISHING
• Finishing flat surfaces: Hold workpiece firmly with both
hands; keep fingers away from abrasive belt.
Use work stop. Work stop is used to position and secure
work being sanded. Keep end butted against work stop and
move work evenly across abrasive belt. Use extra caution
when finishing very thin pieces,
Finishing long pieces: remove work stop. Apply only
enough pressure to allow abrasive belt to remove material.
• Finishing curved edges: Finish outside curves on flat por-
tion of abrasive belt. Finish inside curves on idler drum por-
tion of abrasive belt.
• Finishing end grain: It is more convenient to finish ends of
long wor_ieces with the abrasive belt in a vertical position.
• Move work evenly across the bait.
• For accuracy use miter gauge.
• Adjust belt table angle for beveled work.
USING MITER GAUGE
Refer to Figure 11.
• The miter gauge is used on either the disc or belt table.
Use the miter gauge for securing the work and holding the
proper angle while sanding.
• Adjust angle by repositioning the miter gauge (Key No. 79),
Loosen the knob (Key No. 66) to reposition miter gauge.
• Tighten the knob to secure miter gauge position.
• Miter gauge assembly has a positive stop set-up for 90 °
and 45 ° on either side.
• To use the positive stop, loosen the knob, retract the index-
ing pin (Key No. 75) gently, turn the miter gauge slightly,
slide in indexing pin and turn the miter gauge until the edge
of the screw (Kay No. 77) is stopped by the indexing pin.
• Check accuracy of miter gauge scale (Key No. 72).
• Use a combination square to adjust miter gauge square to
disc. Scale should be at zero. Loosen screw (Key No. 70)
and reposition scale if necessary.
BELT TRACKING
Refer to Figures 10 and 11,
Belt (Key No. 25) should ride centered on drive and idler
drums (Key Nos. 36 and 65). The sander is shipped with the
tracking mechanism properly adjusted. However, if adjustment
is necessary:
• Loosen two knobs (Key No. 45) on either side of belt hous-
ing (Key No. 48).
• Turn the unit on,
• Insert a '/8" or 5/_,,he:<wrench into the hole on adjusting nut
(Key No. 55) on either side.
Figure 10 - Belt Tracking
• Turn the adjusting nut to the right to move belt toward you
or turn the adjusting nut to the left to move belt away from
you.
• Make sure belt rides on the center of drive and idler drums.
• Turn the unit off.
• Replace and tighten knobs on either side of belt housing to
secure tracking adjustment.
REPLACING BELT
Refer to Figures 10 and 11.
• Sanding belt must be replaced when worn, torn, or glazed.
• Push up the belt tension handle (Key No. 52) to release
belt tension.
• Loosen and remove socket head bolt and washer (Key
Nos. 13 and 41).
• Loosen and remove knob and flat washer (Key Nos. 17 and
42).
• Remove support bracket (Key No. 43).
• Loosen and remove four knobs (Key No. 51) from the rear
of the sander.
• Remove belt cover (Key No. 49).
• Slide old belt off the drive and idler drums (Key Nos. 36
and 65).
NOTE: There may be an arrow on the inside of the belt. The
arrow should point down toward the belt table to ensure that
the splice in the belt will not come apart.
• Slide new belt over the drive and idler drums; center belt on
drums.
• Push the belt tension handle toward the drive drum to ten-
sion belt.
• Replace belt cover using knobs from step 6.
• Replace support bracket using hex head bolt, washers and
knob.
• Wear a protective glove and manually rotate the belt by
hand to check tracking. If tracking needs to be
adjusted, follow steps described in "Belt Tracking".
• Make sure belt rides centered on drive and idler drums,
