To realign or replace the cutterhead belt:
1.DISCONNECT THE JOINTER FROM THE POWER SOURCE!
2.While facing the rear of the jointer, tip it away from you until it rests on the fence assem- bly.
3.Remove the Phillips screws fastening the motor cover to the jointer base. Lift the cover off and set it aside.
4.Remove all dust and debris from the motor and belt areas.
5.Inspect the cutterhead belt for proper tension, alignment and condition.
Note: The belt is properly tensioned if it deflects no more than 3/4" when you press down on middle of the belt with moderate pressure from your thumb or forefinger.
The belt is properly aligned if it lies flat and straight on the motor shaft and drive pulley.
Belt damage will be evident on inspection.
6.Loosen the four motor mounting cap screws(see Figure 46), but do not remove them.

7.Replace a damaged belt with a new one. Realign and retension the belt.
8.Tighten the motor mounting screws and replace the motor cover.
9.Test run the jointer. Repeat this procedure if necessary. If repeating this procedure does not solve the problem, call Grizzly Tech Support.
To replace the fan belt:
1.DISCONNECT THE JOINTER FROM THE POWER SOURCE!
2.Remove the motor cover, set it aside and check the belt for damage.
Note: It is highly unlikely that this belt will ever be misaligned or out of tension. If it is, the jointer needs to be serviced by a qualified technician. Call our Tech Support for assis- tance at (570)
3.If the belt is damaged, put one end of the new belt on the fan pulley, then fit the other end onto the drive pulley.
4.Replace the motor cover and secure it with the Phillips screws.
