Installing And Adjusting Sanding Belt - Craftsman 315.11701 Owner's Manual

OPERATION
WARNING: ALWAYS WEAR SAFETY GLASSES OR
EYESHIELDS WHEN OPERATING YOUR SANDER.
IF THE SANDING OPERATION IS DUSTY, ALSO
WEAR A FACE OR DUST MASK. FAILURE TO DO SO
COULD RESULT IN DUST OR LOOSE PARTICLES
BEING THROWN INTO YOUR EYES, RESULTING IN
POSSIBLE SERIOUS INJURY.
INSTALLING AND ADJUSTING SANDING BELT
DISCONNECT SANDER FROM POWER SUPPLY.
To release the sanding belt, push the front pulley
squarely against the top of workbench as shown in
figure 4. When sufficient pressure is exerted, the
spring will be compressed allowing the pulley to
lock in a rear position. This frees the sanding belt so
it can be removed. Install new belt making sure ar-
row inside of belt is pointing in the direction of rota-
tion, which is clockwise when looking into open side
of sander. See Fig. 5. Roughly align the belt to its
correct position. Then place sander into position
shown in figure 6. Insert a screwdriver into slot on
idler pulley yoke and apply backward pressure. The
pulley will snap back into operating position.
To adjust sanding belt, connect Sander to power
supply. Place Sander in upside down position as il-
lustrated. See Fig. 7. NOTE: This position is for ad-
justments only. The Sander is not in an operating
position. Pull switch trigger and release immediate-
ly. Observe tracking of sanding belt. If the sanding
belt runs inward, turn the tracking screw clockwise.
If the sanding belt runs outward, turn the tracking
screw counterclockwise. This should be done until
you are sure belt will not run off sander, or come in
contact with internal parts. After installing a new
sanding belt, it may become necessary to change
the adjustment several times until the belt becomes
pliable.
WARNING: IF SANDING BELT BEGINS TO WEAR
EXCESSIVELY ON THE INNER EDGE, RE-ADJUST
TRACKING SCREW. IT IS ADJUSTED TOO FAR IN.
WARD AND THE SANDING BELT IS RUBBING
AGAINST INTERNAL PARTS. When you are sure the
belt will not rub against internal parts, start the
Sander and fine adjust the tracking screw until the
belt stabilizes.
When correctly adjusted, the outer edge of the belt
will be even with the outer edge of the base of the
Sander. Belt life will be greatly increased if a few
seconds are spent adjusting the belt tracking.
