•
Low oil or no oil
•
Check oil level, adjust level to half of the sight
glass with the vehicle parked on a level surface.
•
Check sump and repair if necessary.

to discharges is correct), or
Discharge hose shaking (slug flow)
•
Using wetting agent and not foam concentrate.
•
Foam proportioning control OFF or turned too low.
•
Foam tank empty
•
Use foam concentrate
•
Increase amount of concentrate delivered to the
manufacturer's recommended amount.
•
Make sure proportioner is turned ON, foam supply
valve is OPEN, foam tank has concentrate, Y
strainer is clean and the supply line is connected
to the injector.
