Maintenance and Troubleshooting
Inspect and Clean Inlet Screen
Inspect inlet screen on pump water inlet.
Clean clogged screen and replace screen if
damaged.
Inspect High-Pressure Hoses
High-pressure hoses can develop leaks from
wear, kinking, or abuse. Inspect hoses before
each use. Inspect for cuts, leaks, abrasions,
bulging, and damage or movement of
couplings. If these conditions exist, replace
hose immediately.
NOTE: DO NOT repair high-pressure hose.
Replace with hose that meets or exceeds
maximum pressure rating of unit.
Inspect Detergent Siphoning Tube
Inspect filter on detergent tube and clean if
clogged. Tube should fit tightly on barbed
fitting. Examine tube for leaks or tears.
Replace filter or tube if either is damaged.
Inspect Spray Gun
NOTE: Replace spray gun immediately if it
fails any test steps.
