Operating Instructions and Parts Manual
Operation (Continued)
START UP (CONTINUED)
Some local plumbing codes require backfl ow prevention when
connecting to a fresh water supply. Install a backfl ow preventer upstream
from the pump if necessary.
a. If inlet water pressure is over 100 psi, install a regulating water valve at the
garden hose connection.
b. Do not exceed 100˚ F (38˚ C) inlet water temperature.
NOTE: The inlet water supply must have a minimum flow rate of 5 gpm (19 lpm).
4. Turn the water supply ON.
Never run the unit dry. Be sure the water supply is completely turned on
before operating the unit.
5. Trigger the gun until water sprays smoothly from the tip indicating that all air is
purged from the system. Lock the trigger safety latch.
6. Open the fuel valve by turning the knob counterclockwise until it stops. Close
the choke (if engine is cold) by moving the choke ring fully to the right. Turn the
ignition switch to "ON".
7. Start the engine. Unlock the trigger safety latch on the gun (See Figure 15). Grasp
the starter rope and brace one foot on the chassis. Point the gun in a safe direction.
While squeezing the trigger on the gun, pull the starter rope rapidly and firmly (See
Figure 16). Continue holding the rope as it returns. Repeat these steps until the
engine starts.
When pulling the starter rope, make sure to keep your hand and arm
clear of the engine and cart components.
Never let the starter rope return by itself. Doing so could jam the
recoil system.
8. If the engine does not start after two or three pulls or if the rope is hard to pull,
squeeze the gun trigger to release the pressure that has built up in the high pressure
hose. Repeat Steps 7 and 8 until the engine starts.

INITIAL HIGH PRESSURE RINSE

Spray the cleaning surface with water to clear off any dirt or grime that may have
collected on the surface. Doing so allows the detergent to attack the deep down dirt
that has worked its way into the cleaning surface.

Adjusting the Spray Fan Angle

Five quick connect tips are available for this pressure washer. The tips have a range of
spray fan angles, ranging from 0°, narrow high impact, to a 65° wide fan spray.
Pressure can also be adjusted by moving closer or further away from the cleaning
surface and by adjusting the spray fan angle as shown.

Angle to the Cleaning Surface

When spraying water against a surface, you can generate maximum impact by striking
the surface head on. However, this type of impact can cause dirt particles to embed in
the surface and can prevent the desired cleaning action.
The optimum angle for spraying water against a cleaning surface is 45°.
Spray water against a surface at a 45° angle to achieve the most beneficial impact force
and to efficiently remove debris (see Figure 19).

Distance From Cleaning Surface

The distance between the spray tip and the cleaning surface is another factor that
affects the impact force of the water. The impact force of the water increases as the tip
is moved closer to the surface.
