Pressure Washers

Operation

1. Surface Preparation

The following cleaning procedure will help you organize your cleaning task and ensures that you will achieve the best results in the shortest amount of time. Remember to use the spraying / cleaning techniques mentioned in the following section.

Before starting a pressure washer cleaning job, prepare the surface you intend to clean. Clear furniture from the area and make sure that all windows and doors are closed tightly. Also, protect all plants and trees near the cleaning area with a drop cloth. A covering ensures that your plants won’t be sprayed by the detergents.

2. Start Up

ALWAYS use this start up procedure to ensure that the unit is started safely and properly.

NOTICE

If water has frozen in the pressure

washer, thaw the pressure washer in a

 

warm room before starting. DO NOT pour hot water on or into the pump; internal parts will be damaged.

1.Check engine oil levels. Add oil as necessary.

2.Check fuel level. Add unleaded gasoline (rated 86 octane or higher) as required

DO NOT refuel a hot engine. Refueling a ! WARNING hot engine could cause a fire. Use only

fresh, clean regular or unleaded gasoline. Close the fuel shutoff valve during refueling.

3.Attach a garden hose to the inlet side of the pump and connect it to the water supply. Use a hose with an internal diameter (I.D.) of 5/8” (1.58 cm) and a length of 50 ft. (15 m) or less.

NOTICE

Some local plumbing codes require

backflow prevention when connecting to

 

a fresh water supply. Install a backflow 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.

 

NOTICE

 

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 from the tip indicating that all air is purged from the system. Set the trigger safety latch.

6.Push the primer bulb three or four times (See Figure 12). Move the throttle fully to the right to the Run or Rabbit position.

Figure 12 – Push the primer bulb 3 or 4 times

7.Start the engine (See Figure 13). 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 (See Figure 13). Continue holding the rope as it returns. Repeat these steps until the engine starts.

Figure 13 - Start the engine

!CAUTION When pulling the starter rope, make sure to keep your hand and arm clear of the

engine and cart components.

NOTICE

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.
