MAINTENANCE
Check and Clean Inlet Screen
Examine garden hose inlet screen. Clean if it is
clogged or replace if it is torn.
Check
High Pressure
Hose
High pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect hose before each use.
Check for cuts, leaks, abrasions, bulging of cover, or
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.
_
ANGER:
Never repair a high pressure hose.
Replace with hose that exceeds the maximum
pressure rating of your pressure washer.
Check Spray Gun and Nozzle Extension
Examine hose connection to spray gun and make sure
it is secure. Test trigger by pressing it and making
sure it springs back into place when you release it.
Engage safety latch and test trigger. You should not
be able to press trigger. Replace spray gun
immediately if it fails any of these tests.
