Nozzle Maintenance; Storing The Pressure Washer - PowerStroke PS80903A Manual Del Operador

NOZZLE MAINTENANCE

Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or
dirty nozzle.
 Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
NOTE: Never point the spray wand at your face.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a fine needle.
 Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).
 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start the engine.

STORING THE PRESSURE WASHER

See Figure 19.
Store the pressure washer with the gas tank empty by either
draining the tank or running the pressure washer until the
gas runs out. Allow 30 minutes of "cool down" time before
storing the machine. Store in a dry, covered area where the
weather can't damage it.
It is important to store this product in a frost-free area. Always
empty water from all hoses, the pump, and the detergent
bucket before storing.
NOTE: Use of a fuel stabilizer and pump saver will give you
better performance and increase the life of the machine.
Discharge Fuel:
Drain the fuel tank completely. Stored gas can go stale in
30 days.
Engine Lubricant:
Drain the lubricant and replace with fresh, clean lubricant.
Spark Plug:
 Disconnect spark plug wire and remove the spark plug.
Pour about a teaspoon of clean, air-cooled, four-cycle
lubricant through the spark plug hole into the combustion
chamber.
 Leaving the spark plug out, pull the starter cord two or
three times to coat the inside of the cylinder wall.
 Inspect the spark plug and clean or replace, as neces-
sary.
 Reinstall the spark plug, but leave the spark plug wire
disconnected.
For winterizing and long-term storage:
 Disconnect the water connection, if necessary.
 Start the pressure washer and allow it to run for a few
seconds to eliminate any water remaining in the pump.
 Coil the hoses and place in the hook-and loop strap on the
unit's handle. Do not allow the hose to become kinked.

CLEANING/REPLACING THE AIR FILTER
See Figure 20.
A dirty air filter will cause starting difficulty, loss of perfor-
mance, and shorten the life span of the engine. Check the
air filter monthly. For best performance, replace the air filter
at least once a year.
 Push the tabs on the air filter cover to open, then remove
 Lift the edge of the air filter carefully and pull it out.
 Lightly tap or blow out dirt particles from filter.
 Reinstall the filter or replace with a new filter if needed.
 Reinstall the air filter cover.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
Hoses and Pump:
Flush the injection hose with clean water for 1-2 minutes.
Remove all hoses. Empty the pump by pulling on the recoil
starter about 6 times. This should remove most of the liquid
from the pump.
PREPARING FOR USE AFTER STORAGE
