recommended oil may result in an engine failure.
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher rated SAE 30
weight. DO NOT use special additives.
1. Choose a viscosity according to the table below:
* The use of multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40°F (4°C) will result in higher
than normal oil consumption. When using a multiviscosity oil, check oil more frequently.
** If using SAE 30 oil in temperatures below 40°F
(4°C), it will result in hard starting and possible
engine bore damage due to inadequate lubrication.
2. Place pressure washer on a level surface.
3. Clean area around oil fill and remove oil dipstick.
3. Wipe dipstick clean. Pour oil into oil fill opening.
4. Replace and tighten dipstick, remove and check
oil level. Oil should be at “Full” mark on the
dipstick. DO NOT OVERFILL.
5. Install oil dipstick, hand tighten securely.
Add Gasoline
WARNING! NEVER fill fuel tank indoors.
NEVER fill fuel tank when engine is running or
hot. Allow unit to cool for two minutes before
refueling. DO NOT light a cigarette or smoke
when filling the fuel tank.
WARNING! NEVER fill fuel tank completely
full. Provide space for fuel expansion. Wipe
away any fuel spillage from engine and
equipment before starting.
1. Use fresh, clean unleaded automotive gasoline
and store in approved, clean, covered containers.
Use clean fill funnels. NEVER use “stale” gasoline
left over from last season or gasoline stored for
long periods.
2. Clean area around fuel fill cap, remove cap.
3. Slowly add gasoline to fuel tank. Use a funnel to
prevent spillage. Fill tank to about 1.5” below top
of the filler neck to allow for fuel expansion.
4. Install fuel cap and wipe up any spilled gasoline.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts, such as the
carburetor, fuel filter, fuel hose or tank during storage.
Also, experience indicates that alcohol–blended fuels
(called gasohol, ethanol or methanol) can attract
moisture, which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. See
“Storage” on page 16. NEVER use engine or
carburetor cleaner products in the fuel tank or
permanent damage may occur.

PRESSURE WASHER
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.
CAUTION! 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.
Check In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
1. Detach spray gun and nozzle extension from high
pressure hose. Detach nozzle extension from
spray gun and remove o-ring and screen from
nozzle extension. Flush screen, spray gun, and
nozzle extension with clean water to clear debris.
