BEFORE STARTING THE ENGINE
Before you operate your pressure washer, you should prepare
the engine for the initial starting. To operate the engine you
will need the following:
H ENGINE OIL
IMPORTANT: Any attempt to crank or start the engine before
it has been properly serviced with the recommended oil results
in an engine failure.
NOTE: When adding oil to the engine crankcase in the future,
use only high quality detergent oil rated with API service clas-
sification SF,SG or SH, rated SAE 30 weight. Select the oil's
viscosity grade according to your expected operating tem-
perature.
Although multi-viscosity otis (5W30, 10W30, etc.) improve
starting in cold weather, these multi-viscosity oils will result in
increased oil consumption when used above 32°F. Check
your engine oil level more frequently to avoid possible damage
from running low on oil. Oil sump capacity is 20 ounces.
* Place pressure washer on a level surface.
. Clean area around oil fill and | remove oil dipstick (Step 8)

WARNING: NEVER FILL FUEL TANK COMPLETELY
FULL. FILL TANK TO ABOUT 1/2” BELOW THE
BOTTOM OF FILLER NECK TO PROVIDE SPACE
FOR FUEL EXPANSION. WIPE AWAY ANY FUEL
SPILLAGE FROM ENGINE AND EQUIPMENT
BEFORE STARTING.
The manufacturer recommends fresh, clean unleaded regu-
lar automotive gasoline with a minimum of 77 octane (Leaded
regular grade is an acceptable substitute).
A
* Use clean fuel and store in approved, clean covered con-
tainers. Use clean fill funnels. Never use “stale” gasoline left
over from last season or gasoline stored for long periods.
* Clean area around fuel fill cap, remove cap (Step 9).

PREPARING THE UNIT FOR
STORAGE
Water should not remain in the unit for long periods of time.
Sediments of minerals can deposit on pump parts and “freeze”
pump action. If you do not plan to use the pressure washer
for more than 30 days, follow this procedure:
1. Flush detergent hose by placing the injector filter into a pail
of clean water while running pressure washer with nozzle
in low pressure mode. Flush for five minutes.
2. Shut off the engine and let it cool, then remove all hoses.
3. Place throttle lever in STOP position.
A
CAUTION: Be sure lever is in “STOP” position
before you continue. If you start engine without
proper water supply connected, you can damage
pump.
4. Empty the pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most of the liquid
in the pump. |
NOTE: To protect unit from freezing temperatures, draw wind-
shield washer fluid into pump by pouring windshield washer
fluid into a 3-foot section of garden hose connected to inlet
adaptor and pulling recoil handle twice.
5. Store in a clean, dry area.
