2. For 80 through 100 pound capacity models only
, lubricate
bearings and seals each month OR after every 200 hours of
operation.
a. Use a premium-grade lithium-based #2 grease. Never mix
two types of grease, such as petroleum and silicone.
b. Pump the grease gun slowly, permitting only 2 strokes for
each bearing grease fitting.
NOTE: Do not pump the grease gun until grease
comes out of the bearing housing. This can result in
over lubrication, causing damage to bearings and
seals.
3.
Check overflow hose and drain hose for leaks.
4.
Check the supply dispenser hoses and hose connections.
5.
Clean inlet hose filter screens:
a. Turn water off and allow valve to cool, if necessary.
b. Unscrew inlet hose and remove filter screen.
c. Clean with soapy water and reinstall. Replace if worn or
damaged.
