· Once a year you should clean or replace the
spark plug, clean or replace the air filter. A new
spark plug and clean air filter assure proper
fuel-air mixture and help your engine run bet-
ter and last longer. Please refer to your engine
operator’s manual for more details.
PRESSURE WASHER MAINTENANCE
Clean Debris
Daily or before use, clean accumulated debris
from cleaning system. Keep linkage, spring and
controls clean. Keep area around and behind
muffler free from any combustible debris.
Inspect cooling air slots and openings on the
pressure washer. These openings must be kept
clean and unobstructed.
NOTICE: Improper treatment of pressure wash-
er can damage it and shorten its life. DO NOT
insert any objects through cooling slots.
Cleaning system parts should be kept clean to
reduce the risk of overheating and ignition of
accumulated debris. Use a damp cloth to wipe
exterior surfaces clean. Use a soft bristle brush
to loosen caked on dirt, oil, etc. Use a vacuum
cleaner to pick up loose dirt and debris.
Check and Clean Inlet Screen
Examine the screen on the pump water inlet.
Clean it if the screen is clogged or replace it if
screen is damaged.
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 condi-
tions exist, replace the hose immediately.
WARNING: The high pressure stream of
water that this equipment produces can cut
through skin and its underlying tissues, lead-
ing to serious injury and possible amputation.
NEVER repair high pressure hose. Replace it.
Replacement hose rating MUST exceed maxi-
mum pressure rating of unit.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and
clean if clogged. The tube should fit tightly on
the barbed fitting. Examine the tube for leaks
or tears. Replace the filter or tube if either is
damaged.
Check Gun
Examine the hose connection to the spray gun
and make sure it is secure, and make sure the
“Safety Lock” is present attached on the trig-
ger, it helps to prevent any accident jets when
in operating. Replace spray gun immediately if
it the “Safety Lock” is damage or not works.
Check Spray Wand
Occasionally, the spray wand can become
clogged with foreign materials such as dirt.
When this happens, excessive pressure can de-
velop. Whenever the pressure nozzle becomes
partially clogged, the pump pressure will pul-
sate. It should be immediately cleaned.
PUMP OIL MAINTENANCE
Changing Pump Oil
Change oil after first 50 hours of operation and
then every 200 hours or 3 months, whichever
occurs first.
NOTE: When changing pump oil, use only high
quality non-detergent 30 weight oil. Use no
special additives.
Change pump oil as follows:
1. Clean area around brass oil drain plug at
bottom of pump.
2. Remove oil drain plug. Drain oil completely
into an approved container.
3. When oil has completely drained, install oil
drain plug and tighten firmly.
4. Clean area around pump oil dipstick. Re-
move dipstick and fill pump with recommend-
ed oil to full mark on dipstick.
5. Install pump oil dipstick.
6. Wipe up any spilled oil.
Engine Maintenance
See the engine operator’s manual for instruc-
tions on how to properly maintain the engine.
WARNING: Avoid prolonged or repeated
skin contact with used motor oil. Used motor
oil has been shown to cause skin cancer in cer-
tain laboratory animals. Thoroughly wash ex-
posed areas with soap and water.
