7. Start the engine: Unlock the trigger safety latch on the gun. Grasp the starter rope
and brace one foot on the chassis. While squeezing the trigger on the gun, pull the
starter rope rapidly and firmly. 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.
Trigger the gun 3 to 5 times to get any trapped air out of the system. After the spray
becomes constant, you may need to adjust the pressure.

Pressure Adjustment

Please refer to your CAT pump manual for specific pressure adjustment details.

Adjusting the Spray Fan Angle

Five quick connect tips are included with 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 21).

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.

How to Avoid Damaging Surfaces

Damage to cleaning surfaces occurs because the impact force of the water exceeds
the durability of the surface. You can vary the impact force by controlling the spray
tip angle to the cleaning surface and the distance from the cleaning surface and by
changing the spray tip. NEVER use a narrow high impact stream on a surface that is
susceptible to damage. Avoid spraying windows with a narrow high impact stream.
Doing so may break the window. The most sure way to avoid damaging surfaces is to
follow these steps:
1. Before triggering the gun, make sure the quick connect tip you are using is
appropriate for the application.
2. Place the spray tip approximately 4-5 feet (1,22-1,52 m) away from the cleaning
surface. Then hold the lance and spray tip at a 45° angle to the cleaning surface.
Trigger the gun.
