OPERATING INSTRUCTIONS

Engine with fixed throttle:
Move the engine stop switch to the ON
position.

Step 9

Pull the starter handle.
If the engine fails to start after 3 pulls,
squeeze the trigger gun to release
pressure, and repeat step.

Important!

Do not run the engine with a high or low oil
level as this can cause engine damage.

If you have further questions regarding the
engine, please refer to the engine’s
operating manual included with the unit.

Step 1

Check oil level on engine before starting the
unit. Oil level should always be between the
“FULL” and “ADD” marks on the dipstick.
Be sure the machine is level when checking
the oil level. (Refer to the engine’s operating
manual for seasonal grades.).

We recommend that the oil be changed after
the first 2 hours of use, then once every 25
hours.

Step 2

Fill gas tank with unleaded gasoline.
Do not use leaded gasoline.

Step 3

Connect the high pressure hose to the unit’s
high pressure outlet.

Step 4

Connect garden hose to unit’s water inlet.

Step 5

Connect garden hose to the cold water
source and turn water on completely.
Do not use hot water.

Step 6

Trigger the gun to eliminate trapped air, wait
for a steady flow of water to emerge from
the spray nozzle.

Step 7

Set choke lever to the CLOSED position
Starting a Warm Engine:
If the engine has run out of fuel, set choke
lever to the CLOSED position after refueling.
If the engine has not run out of fuel, leave
the choke lever in the OPEN position.

Step 8

Engine with manual throttle:
Slide the throttle lever away from the SLOW
position, about 1/3 of the way toward the
FAST position.

MAINTENANCE INTERVALS FOR PUMP

We recommend that the oil be changed after
the first 100 hours of use, then once every
500 hours.

Recommended oil for pump

Use multi-grade 4-stroke motor oil that meets
or exceeds the requirement for API service
classification SH, SJ, or equivalent.
Use oil SAE-class 15W-40.

Oil Change for pump

Drain the pump oil when the pump is warm.
Warm oil drains quickly and completely.
1. Place a suitable container below the pump

to catch the used oil.

2. Remove the oil fill cap, the oil drain plug

and washer.

3. Allow the used oil to drain completely, then

reinstall the drain plug and washer. Tighten
the drain plug securely.

Please dispose of used oil in a manner that
is compatible with the environment. We
suggest you take used oil in a sealed
container to your local recycling center. Do
not throw it in a trash or pour it on the ground
or down a drain.

4. With the pump in a level position, fill in

0.350 liters (11.84 Fl.oz) of recommended
oil. Do not overfill.

Notice:

Running the pump with a low oil level can
cause pump damage.
5. Reinstall the oil fill cap securely.

For more details see engine manual.
