OPERATING INSTRUCTIONS
Belt tensioning: The 6" x 48" belt sander has a preset belt tension. The yoke assembly is spring loaded for constant belt
tension. Tension lever (#30) tightens and loosens belt tension.
Belt changing: Open belt guard (#47) and locate the tension lever (#30) between the sander frame (#27). Pull down
tension lever (#30) 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 (#30) to allow re-tensioning of the
belt. Check tracking of belt with short on/off jobs of motor before letting the machine run. Spinning the belt by hand with
power off with 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 (#42) on yoke assembly. Tightening knob (#42)
raises idler spindle (#39) and the belt moves toward the frame (#27). Loosening the tracking knob (#42) drops the idler
spindle (#39) and the sanding belt moves away from the frame (#27). When the belt is centered on the platen (#36), tighten
jam nut that's located on tracking knob (#42) to lock in belt position.
Trouble shooting/tracking problems
1. Drive pulley lost its crown (curvature of pulley).
2. Sanding belts are not spliced/glued correctly.
3. Upper pulley assembly not squared to platen. (Used carriage bolts to square yoke with platen.
4. Upper pulley isn't flat.
Sanding head position: Sanding head be position from vertical to horizontal with any angle in between. Loosen 5/16" hex
bolts (#18 located above/below #19 spindle) slightly to re-position the sanding head then tight 5/16" bolts (#18) when you
reach your desired position. Note: sander head heavy so make sure you firmly hold the sander head when adjust
sander head angle.
Platen: The platen (#36) is located behind the sanding belt. The platen (#36) can be reverse and flipped to give you four
sanding areas. Normal wear will occur and the platen will need to be rotated occasionally depending on usage. Remove
sanding belt and platen screws (#43) rotate platen to new position.
Worktable: The worktable (#44) has a slot of mounting fixtures or a mitre gauge. also, Two mounting holes are provided on
the side of the sander frame (#27) move the worktable (#44) to different work heights. Note: Keep worktable (#44)
within 1/8" of sanding belt.
Coolant: Use rust inhibiting coolant. Using straight water will rust sander components and will void machine
warranty. Consult your coolant dealer for proper coolant selection.
