Instruction sheet for S660M AND S660MV belt sanders
Belt tensioning: The 6" x 60" belt sander has a preset belt tension.
The yoke assembly is spring loaded for constant belt tension.
Tension lever (#29) tightens and loosens belt tension.
Belt changing: Open belt guard (#42) and locate the tension lever
(#29) between the sander frame (#23). Pull down tension lever
(#29) to compress tension spring and release belt tension.
Remove and replace sanding belt. Be sure of correct belt rotation.
Look inside belt for arrows showing you correct rotation. Lift tension
lever (#29) to allow re-tensioning of the belt. Check tracking of belt
short on/off jogs of motor before letting the machine run. Spinning the
belt by hand with power off will also check rough tracking before
running machine. Be sure sanding belt stays centered on platen.
Belt tracking: Tracking the sanding belt is done with the tracking knob
(#35) on yoke assembly. Tightening knob (#35) raises idler spindle
and the belt moves toward the motor. Loosening the tracking knob
drops the idler spindle (#28) and the sanding belt moves away from
the motor. When the belt is centered on the platen (#33), tighten jam nut
on tracking knob to lock in belt position.
Troouble shooting and tracking problems
• Drive pulley lost its crown (curvature of pulley)
• Sanding belt are not spliced square.
• Upper pulley assembly not square to platen.
(Use carriage bolts to square yoke with platen.)
