HP-400P HORIZONTAL BAND RESAW -49-
Adjusting V-Belt Tension
Properly tensioned V-belts help the Model HP-400P operate at its best. However, adjusting the V-belts is not
an exact science and does require personal judgement. Adjusting the belts too loose will decrease the
performance of the machine and adjusting the belts too tight may cause premature wear of the bearings and
other components attached to the belts.
On the Model HP-400P there is a triple-drive V-belt system that connects the motor to the wheel pulley and a
single-drive V-belt system that connects the wheel pulley to the hydraulic pump.
On both systems, the belts should deflect no more than 1/2" and not less than 1/4" when pressing between the
pulleys with your index finger.
To adjust the V-belt tension for the saw wheels
：
1. Disconnect the resaw from the power source.
2. To tension the three V-belts that connect the motor to the wheel pulley, adjust the tension by moving the
motor mount nuts up or down until the belts are in the proper deflection range.
Note—The belts tighten when you move the motor mount up.
To adjust the tension for the hydraulic pump V-belt
：
1. Remove the small pulley cover from the pump seat.
2. Adjust the belt tension by loosening the cap screws.
3. Rotate the pump seat up or down until the belt has the proper deflection.
4. Tighten the cap screws to lock the pump seat in place.
5. Re-install the pulley covers.
