TROUBLESHOOTING
Pump Loses Pressure: Do not run the pump without the washer
screen #98180 in the intake. Debris may cause damage to the
pump or may cause the pump to loose pressure. If the pump does
not build pressure, there may be debris lodge in the check valves.
There are two check valves under each end cap. Remove the end
caps using a 5mm hex wrench and inspect the check valves. If the
issue is not solved, the pump seals may have to be replaced using
Seal Kit #48181.
PERIODIC MAINTENANCE:
Every 100 hours, inspect and lubricate the piston and bearing.
This is behind the front cover plate of the pump. To access this
area, remove the four screws and take off the cover plate. Do not
remove the front cover plate while the pump is plugged in or run-
ning. Never run a pump without reinstalling the front cover plate.
Lubricate with a water resistant, all-purpose lithium grease.
