801 195-A / Ref. 801 194
! Disconnect cooler plug from
welding power source re-
ceptacle before maintaining.
1 Coolant Filter
Unscrew housing to clean filter.
Changing coolant: Drain coolant by
tipping unit forward. Fill with clean
water and run for 10 minutes. Drain
and refill.
. If replacing hoses, use hoses
compatible with ethylene gly-
col, such as Buna-n, Neo-
prene, or Hypalon. Oxy-acety-
lene hoses are not compatible
with any product containing
ethylene glycol.

12. Troubleshooting
Trouble Remedy
Coolant system does not work. Be sure input power cord is plugged in to energized receptacle.
Check line fuses or circuit breaker, and replace or reset if necessary.
Motor overheated. Unit starts running when motor has cooled.
Have Factory Authorized Service Agent check motor.
Decreased or no coolant flow. Add coolant.
Check for clogged hoses or coolant filter.
Disconnect pump, and check for sheared coupling. Replace coupling if necessary.
