TROUBLESHOOTING GUIDE
3. AGITATION SYSTEM

The Agitator will not rotate or moves extremely slow. Does the
material pump turn at the proper speed? If yes, try the adjustment
listed above. The Agitator should now rotate properly. If it doesn’t,
then the agitator motor needs replacing. Does the motor shaft turn
but the sprockets do not? Check the motor for a sheared key. If the
material pump doesn’t rotate at the proper speed either, have the
hydraulic pump tested.

Hydraulic oil level. The level should be 4” down from the tank top. Use
grade AW68, SAE 10w20, or 10w30 hydraulic oil.

If sealer leaks from around the shaft. If the sealer is leaking from the
sprocket end of the shaft, the seal needs replaced. As long as the
sealer hasn’t been allowed to get into the bearing, it will not need
replacing. If rear bearing needs replacing, clean shaft well with emery
cloth before attempting to install new seals and bearing.

If the tank has a packing gland. Packing needs to be added.
