TROUBLESHOOTING
POSSIBLE CAUSES
Relief setting in auxiliary system lower
than standard 2400 psi.
Loader circuit pump or auxiliary pump
failure.
Tilt clamp bolts set too tight or rusted
plate.
Excess motor case drain pressure.
No power to controller.
Check power to coil.
Improper lubrication of bearing. Pick
holder replacement-welder not
grounded through drum.
CHECK THE FOLLOWING
Remove and clean or replace solenoid
cartridge or replace O-rings. Check
reliefs in the following sequence -
loader valve, standard auxiliary valve.
Reset or replace any relief below 2200
psi. The flow should be no less than 25
gpm. If pump output is 20% less than
rated pump specifications, the pump
may require repair. Consult loader ser-
vice manual.
Loosen tilt clamp bolts to provide .015
clearance or grease between plates.
The maximum case drain pressure
allowed is 25 psi at full engine throttle.
Replace shaft seal.
Check fuse and power lead connec-
tions.
If coil has power and pulls, cartridge is
defective; replace cartridge. If coil
doesn't pull check for power to coil or
replace coil.
Re-grease outboard bearing each 4 - 8
hours. During holder replacement,
ground welder directly to drum. (See
Service section.)
