CONVEYOR BELT TENSION
Insufficient belt tension will cause slippage of
conveyor belt on the drive roller during sanding ope-
ration. The conveyor belt is too loose if it can be stop-
ped by hand pressure applied directly to the top of the
conveyor belt. Excessive belt tension can result in bent
rollers, premature wearing of the bronze bushings or
conveyor belt
To adjust the tension of the conveyor belt, first adjust
the take-up screw nut on both sides of the conveyor
to obtain approximately equal tension on both sides
of the belt when taut (see opposite picture).
CONVEYOR BELT TRACKING
Belt tracking adjustments are made while the conveyor belt is running. After the proper belt tension is obtained
turn the conveyor unit on and set it at the fastest speed setting. Watch for a tendency of the conveyor belt to drift
to one side of the conveyor. To adjust the belt tracking, tighten the take-up screw nut on the side the belt is drifting
toward, and loosen the take-up screw nut on the opposite side. Adjusting the take-up screw nuts on either side of
the conveyor allows belt-tracking adjustments to be made without affecting belt tension. Note: Adjust the take-
up screw nuts only 1/4 turn at a time. Then allow time for the belt to react to the adjustments before proceeding
further. Avoid over-adjustments.
MAINTENANCE
MONTHLY MAINTENANCE CHECKLIST
• Lubricate conveyor bushings and check for wear.
• Lubricate with a dry lubricant spray all of the moving parts, such as threaded rods and washers.
• Clean dust from conveyor belt.
• Check all set screws for tightness.
• Clean drum and abrasives if necessary.
REPLACING CONVEYOR BELTS
To replace the conveyor belt, the conveyor assembly must be removed from the machine.
1. Raise the drum carriage to its highest position
using the height adjustment handle.
2. Turn off power source to machine. Unplug main drive
motor from receptacle (in gear motor assembly).
3. Loosen the conveyor take-up screws to relieve belt
tension and slide the drive roller fully inward.
4. Remove the two Allen head bolts on the inboard
(right) side that attach the conveyor assembly to
the base.
5. Remove the two nuts and washers from outboard
(left) side (see opposite picture).
6. Lift the conveyor and remove it from the sander.
Set conveyor on motor side. Avoid tearing the belt
on any edges underneath the conveyor bed during removal. Reverse the procedure for re-installation. Re-install
the conveyor bed to sander.
