309828 7

Operation

Startup

Always use this startup procedure to ensure that the pressure washer is started safely and properly.

DAlways engage gun trigger safety latch when you stop spraying. This reduces the risk of fluid injection or splashing in eyes or on skin if gun is bumped or accidentally triggered.

DAlways observe the CAUTIONS in this section to avoid costly damage to pressure washer.

DIf you use the Sandblaster Kit, see Sandblaster Kit Manual for detailed cleaning information.

1.Check oil level. of engine.

2. Check fuel level.

3. Turn on water supply.

CAUTION

Never run pressure washer without wa- ter. Costly pump damage will result. Always be sure water supply is complete- ly turned on before you run pressure washer.

8 309828

4. Trigger gun until a constant stream of water sprays from tip indicating air is purged from the system.

5. Be sure spark plug ignition cable is pushed firmly onto spark plug.

ti3242a

ti3240a

7.Pull the starter rope quickly to start the engine. Pull and return the rope until the engine starts. HINT: Placing one foot on the pres- sure washer as a brace provides better leverage.

NOTE: For easier starting, have one person start pressure washer while another triggers gun.

CAUTION

DDo not allow pressure washer to idle more than 10 minutes. This causes circulating water to overheat and serious damage to the pump. The pump is equipped with a thermal valve to help prevent severe damage if circulating water is overheating.

DTurn off pressure washer if it will not be spraying at least every 10 minutes or if thermal valve activates. If heated inlet water is used, reduce this time.

DDo not operate pressure washer with inlet water screen removed. This screen helps keep abrasive sediment which could clog pump or damage cylinders, out of pump.

DDo not pump caustic materials.

309828 9

8.Carefully install manifold and torque bolt to 443 in.???lbs (37 ft???lbs).

Note: Valve life is dependant on many variables. Hard water, cavitation, corrosion, chemicals and equipment care. The valves are a wear item and need periodic replacement. Worn o???rings or damaged valves will cause pressure loss and pulsations.

309828 19

Packings

Disassembly

1.To access water seals for inspection or replace- ment, remove head of pump.

Note: It is important to note the order in which the components of the packing stack are arranged and facing during disassembly.

2.Remove head bolts.

3.Insert a small pry bar between head and body at opposite corners and apply pressure down on one pry bar and up on the other pry bar.

4.Lift head up and away from body.

Note: Packing stack will not always stay in head of pump when it is removed. Sometimes one or more components of the packing stack will come out of the head and stay on the plunger.

5.To remove any components that stay on plungers twist back and forth while pulling up.

6.Remove low???pressure seals by inserting a flat screwdriver under seal lip and lifting up.

7.Remove piston guides from head by using a re- verse pliers (preferably rubber coated) inserted into center of piston guide.

8.Use back and forth twisting motion while pulling up (clockwise and counter???clockwise).

9.Another method is to use a two???prong slide ham- mer puller. Insert prongs into piston guide allowing prongs to grab under support ring, then use slide hammer to pull packing stack up and out of head.

Note: Damage to piston guides and or seals may occur during removal. Inspect carefully before reusing any components of packing stack.

10. Remove high???pressure packing by pulling straight out with your finger.

Assembly

1. Install high???pressure seal into head.

Note: It should fit snugly. The packing support is part of the valve cage.

2.Place high???pressure seal at an angle and work it into cylinder.

Note: The point of the ???v??? or flat side of packing is pointed at you.

3.Lubricate packing retainer o???ring with a light film of oil and install it into cylinder.
