WARNING

SKIN INJECTION HAZARD

Spray from gun, leaks or ruptured components can inject fluid into your body and cause serious injury. Fluid splashed in eyes or on skin can also cause serious injury.

D Fluid injected into skin may look like just a cut, but it is a serious injury. Get immediate surgical

treatment.

D Do not point gun at anyone or at any part of body.

D Do not stop or deflect leaks with hand, body, glove or rag.

WARNING

This symbol alerts you to the possibility of serious injury or death if you do not follow instructions.

Caution Symbol

CAUTION

This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow instructions.

D Do not put hand or fingers over spray tip.

D Tighten fluid connections before starting equipment.

D Engage gun trigger safety whenever spraying is stopped.

D Follow Pressure Relief Procedure on page 6 if spray tip clogs and before cleaning, checking or

servicing equipment.

D Repair or replace worn or damaged parts immediately.

D Check hoses, tubes, and coupling daily. Do not repair high pressure couplings: replace entire hose.

Fluid hoses must have spring guards on both ends to prevent kinks and rupture.

Setup

Check for Shipping Damage

Check the unit for any damage that may have occurred in shipping. Notify the carrier immediately if there is any damage.

Set Up

Charge the battery. Be sure the battery connections are correct and secure. Connect the fuel line to the engine using the quick coupler provided. Squeeze the priming bulb 3 to 5 times. If you are using a downstream chemical injector, install it between the pump unloader and the high pressure hose, using the quick couplers provided.

Connect the high pressure hose between the pump outlet and the gun inlet. Both of these connections are made with quick couplers.

CAUTION

Up to 100 ft (30 m) of high pressure hose may be used. Longer hoses may affect sprayer performance, and chemical injector performance, if used.

Install the appropriate spray tip on the wand. See Installing and Changing Spray Tips. If you are using a sandblaster kit, see its separate manual for installation instructions.

Connect to Water Supply

CAUTION

Before attaching to the water supply, check your local plumbing code regarding cross--connection to the water supply. Use a backflow preventer if required by local code.

Do not exceed 160_F(70_C) inlet water tempera- ture.

Connect a hose with at least a 3/4 inch (19 mm) ID from the water supply to the unit’s 3/4 inch garden hose inlet. The supply hose should not be more than 50 ft (15 m) long.

NOTE: The water source at the unit must have a

minimum flow rate equal to that of the unit (see Technical Data, inside back cover).

Operation

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

System pressure must be manually relieved to prevent system from starting

or spraying accidentally. Fluid under high pressure can be injected through skin and cause serious injury. To reduce risk of injury from injection, splashing fluid, or moving parts, follow Pres- sure Relief Procedure whenever you:

D are instructed to relieve pressure, D stop spraying for more than 10 minutes, D check or service system equipment, D install or clean spray nozzle.

1. Engage trigger safety latch.

2. Turn sprayer off.

3. Remove ignition cable from spark plug.

4. Remove siphon tube from water supply.

NOTE: This pressure washer is equipped with a

low--oil sensor that shuts the engine off if the oil level falls below a certain level. If the unit stops unexpectedly, check both the oil and the fuel levels. Check the oil level each time the unit is refueled.

2. Check fuel level.

WARNING

FIRE HAZARD

Do not refuel a hot engine. Refueling a hot engine could cause a fire. Use only fresh, clean regular or unleaded gaso-

line. Close fuel shutoff valve during refueling.

3. Turn on the water supply.

CAUTION

Never run unit dry. Costly damage to pump will result. Always be sure water supply is sufficient before operating.

4. Trigger the gun until water sprays from the tip indicating that the air is purged from the system.

5. Open the fuel shutoff valve. Be sure the spark plug ignition cables are pushed firmly onto the spark plugs. Put the ignition shutoff switch in the “on” position and the throttle in the “run” position.

5. Disengage trigger safety latch and trigger gun to relieve pressure. Engage trigger safety latch.

6. If spray tip or hose is completely clogged, or

pressure has not been fully relieved after following steps above: Disengage trigger safety latch and

trigger gun to relieve pressure. Wrap rag around hose end coupling and VERY SLOWLY loosen coupling to relieve pressure gradually, then loosen completely. Now clear tip or hose.

Startup

1. Check oil levels. D Engine: Add SAE 30 or 10W--30 weight deter-

gent oil as necessary.

D Pump: Add SAE 20 or 30 weight non--deterg-

ent oil.

6. Start the engine.

NOTE: For easier starting, have one person start the

pressure washer while another person triggers the spray gun.

If the engine is cold, completely close the engine choke. Press the start button. In cool weather, the choke may have to be kept closed for 10 to 30 seconds before opening it to keep the engine running. Otherwise, open the choke as soon as the engine starts.

If the engine is warm, leave the choke open or partially closed. Start the engine as described in the preceding paragraph. When the engine starts, be sure to open the choke completely.

7. ALWAYS engage the gun’s trigger safety latch whenever you stop spraying, even for a moment, to reduce the risk of fluid injection or splashing in the eyes or on the skin if the gun is bumped or triggered accidentally.

8. ALWAYS observe the following CAUTIONS to avoid costly damage to the pressure washer.

3085326

Operation

CAUTION

Pressure washer is equipped with a thermal relief valve. If pressure washer is operated without spraying for an extended period (approximately 10 minutes) the valve will expel hot water.

Do not operate pressure washer with inlet water screen removed. Keep screen clean. Screen keeps abrasive sediment out of pump, Abrasive sediment can clog pump or damage cylinders.

Do not pump caustic materials; such materials may corrode pump components.

9. See the chemical injector or sandblaster kit manual for detailed cleaning information if these accessories are used.

Trigger Safety Latch

WARNING

TRIGGER SAFETY LATCH SHOWN ENGAGED

Figure 2a

To reduce risk of serious bodily injury, including fluid injection, splashing in eyes or on skin, always engage trigger safety latch when spraying is stopped, even for a moment. In engaged position, trigger safety latch prevents gun from being triggered accidentally by hand or if dropped or bumped. Be sure to push down latch fully to engage it. If latch not fully engaged, gun can accidentally trigger. See Figures 2a and 2b.
