Nozzle Maintenance; Pump And Motor Maintenance - Craftsman 580.752850 Manual Del Operador

Check and Clean Water Inlet Screen
Remove water inlet coupling (A). Then remove water inlet
screen (B) from the unit's water inlet (C) using a needle nose
pliers. Water inlet is located at bottom front of unit. Examine
water inlet screen. If the screen is dirty, clean with a small
brush and water. If the screen is damaged, replace it.

Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before using it.
Check for cuts, leaks, abrasions or bulging of cover, damage
or movement of couplings. If any of these conditions exist,
replace the hose immediately.
WARNING The high pressure stream of water that this
equipment produces could cut through skin and
its underlying tissues, resulting in serious injury
and possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST equal or exceed
maximum pressure rating of unit.
Check Spray Gun
Examine the hose connection to the spray gun and make sure
it is secure. Test the trigger (D) by pressing the trigger lock
button (E) and making sure the trigger "springs back" into
place when you release it. You should not be able to press
the trigger without pressing the trigger lock button. Replace
spray gun immediately if it fails any of these tests.

Nozzle Maintenance

Excessive pump pressure can cause a pulsing sensation felt
while squeezing the spray gun trigger. The principal cause
of excessive pump pressure is a nozzle clogged or restricted
with foreign materials such as dirt, etc. A clogged nozzle
could lead to pump cycling ON/OFF or not turning on even
when there is some fl ow.
To correct the problem, immediately clean the nozzle by
following these instructions:
1. Press the master ON/OFF switch to the OFF (O) position.
Remove power cord plug from electrical outlet.
2. Disconnect water supply at the electric pressure washer.
3. ALWAYS point spray gun in a safe direction, press trigger
lock button and squeeze spray gun trigger to release
retained high water pressure.
WARNING The high pressure stream of water that this
equipment produces could cut through skin and
its underlying tissues, resulting in serious injury
and possible amputation.
Spray gun traps high water pressure, even when motor is
stopped and water is disconnected, which could result in
serious injury.
• Keep high pressure hose connected to pump and spray
gun while system is pressurized.
• ALWAYS point spray gun in safe direction, squeeze
spray gun trigger to release high pressure, every time
you turn off pressure washer.
4. Insert end of wire tip cleaner (F) repeatedly into small
opening of nozzle (G) to remove any clog or sediment
buildup. The wire tip cleaner is stored at the lower back
left of the unit.
5. Make sure garden hose is connected to water inlet. Check
that high pressure hose is connected to spray gun and
pump. Turn on water.

6. Plug power cord into electrical outlet and press the
master ON/OFF switch to the ON ( | ) position.
7. Test the electric pressure washer by operating with the
wand.

Pump and Motor Maintenance

The electric pressure washer does not require any
maintenance to the pump or motor. Both assemblies are pre-
lubricated and sealed, requiring no additional lubrication ever.
