Installation

Check for Shipping Damage

Check unit for any damage that may have occurred in

shipping. Notify carrier immediately if there is any dam-

age.

Set Up

Connect high pressure hose (K) between pump outlet

and 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 perform-

ance, and chemical injector performance, if used.

Install desired spray tip (H) on spray gun (G). See Install-

ing and Changing Spray T ips. If you are using a

sandblaster kit, see its separate manual for installation

instructions.

Water Supply

CAUTION

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

ture.

Insert siphon tube (P) in container providing clean water

source.

NOTE: The water supply must be able to provide water

at a minimum flow rate equal to that of unit while

its being used (see Technical Data on

page 17).

6308736

Operation

Pressure Relief Procedure

WARNING

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 injec-

tion, splashing fluid, or moving parts, follow Pres-

sure Relief Procedure whenever you:

Dare instructed to relieve pressure,

Dstop spraying for more than 10 minutes,

Dcheck or service system equipment,

Dinstall or clean spray nozzle.

Pressure Relief Procedure

1. Engage trigger safety latch.

2. Turn sprayer off.

3. Remove ignition cable from spark plug.

4. Remove siphon tube from water supply.

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

Always use start–up procedure to ensure that unit is

started safely and properly.

1. Check oil level:

NOTE: All units are equipped with a low-oil sensor that

shuts engine off if oil level falls below a certain

level. If unit stops unexpectedly , check both oil

and fuel levels. Check oil level each time 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.

CAUTION

Never run unit dry. Costly damage to pump will

result. Always be sure water supply is sufficient

before operating.

3. Put siphon tube in water supply. For best perfor-

mance, place siphon tube and water source at the

same or higher level than pressure washer.

7308736

Operation

4. Trigger gun until water sprays from tip indicating

that air is purged from system.

5. Open fuel shutoff valve. Be sure spark plug ignition

cable is pushed firmly onto spark plug. Put switch

in ON position and put throttle in RUN position.

CAUTION

Do not allow pressure washer to idle more than 10

minutes. Doing so may cause recirculating water to

overheat and seriously damage pump. Turn off

pressure washer if not spraying or cleaning at least

every 10 minutes. If heated inlet water is used,

reduce time further. 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.

CAUTION

Do not allow starter rope to snap back against

engine. Return carefully to prevent damage to

recoil.

6. Start engine.

If engine is cold, completely close engine choke.

Grasp starter rope, brace one foot on pressure

washer chassis and pull rope rapidly and firmly.

Continue holding rope as it returns. Pull and return

rope until engine starts. In cool weather, choke

may have to be kept closed for 10 to 30 seconds

before opening it to keep engine running. Other-

wise, open choke as soon as engine starts.

If engine is warm, leave choke open, or partly

open. Start engine as described in preceding para-

graph. When it starts, open choke completely.

Operate engine at reduced rpm to assist priming.

When water flows from return hoses pump is

primed. Raise engine to full rpm for normal pres-

sure washer operation.

7. Always engage gun’s trigger safety latch when

spraying is stopped, even for a moment. This

reduces risk of fluid injection or splashing in eyes

or on skin if gun is bumped or triggered acciden-

tally.

8. Always observe preceding CAUTIONS to avoid

damage to pressure washer.

9. See sandblaster kit manual for detailed cleaning

information if this accessory is used.

Operation

Trigger Safety Latch

WARNING

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 trig-

gered accidentally by hand or if dropped or

bumped. Be sure to push down latch fully to en-

gage it. If latch not fully engaged, gun can acciden-

tally trigger. See Figure 2.

Chemical Injector Operation

WARNING

To reduce risk of serious bodily injury, including

fluid injection or splashing in eyes or onto skin, use

extreme caution when changing spray tips. Always

follow procedure below.

1. Follow Pressure Relief Procedure.

2. Insert chemical filter (attached with clear tubing to

chemical injector) into container of chemical.

3. Install black spray tip for chemicals (see Installing

and Changing Tips).

The large hole of the chemical spray tip causes a drop

in pressure that actuates the chemical injector. Chang-

ing back to a smaller diameter spray tip deactivates

the chemical injector and produces high pressure for

rinsing. The chemical filter can be left in the chemical

container during high pressure use. The flow rate of

the chemical may be regulated by turning the chemical

adjustment knob on the injector. The maximum chemi-

cal flow is a full two turns counterclockwise from the

closed (clockwise) position.

Operation

Installing and Changing Spray Tips

WARNING

To reduce risk of serious bodily injury, including

fluid injection or splashing in eyes or onto skin, use

extreme caution when changing spray tips. always

follow procedure below.

1. Follow Pressure Relief Procedure.

2. Point gun and wand away from yourself and any-

one else.

3. Spray tips have a 4– or 5–digit number on them.

The first two digits are spray angle. Select spray

tip appropriate for application.

Spray Tip Number Spray Pattern Fan Angle

00XXX 0_, blaster (red)

15XXX 15_ (yellow)

25XXX 25_ (green)

40XXX 40_ (white)

NOTE: The chemical injector spray tip is brass with large

diameter hole and black cap.

4. Point spray tip (A) away from hands and body. Pull

back quick coupler ring (B). Remove tip with fin-

gers and hand to side of spray tip. Replace tip and

push back ring. See Figure 3.

5. Pull on tip to be sure it is secure.

6. Storage for spray tips is provided on chassis next

to pump.

CAUTION

O-ring (801202) may be blown out of quick coupler

(B) due to high pressure in system. Never operate

pressure washer without tip (A) securely mounted

in quick coupler.

Operation

Shutdown, Flushing and Storage

NOTE: For easier flushing, use anti –freeze flush kit

802327.

CAUTION

If water freezes in pressure washer, thaw in warm

room before trying to start it. Do not pour hot water

on or into pump. Hot water may crack ceramic

plungers!

1. If pressure washer is used or stored in freezing

temperatures, drain all water out of pump after

use. Flush with 50% anti–freeze solution. Relieve

pressure. Flush before using to remove anti–

freeze.

2. Before long-term (overnight) storage or transport,

disconnect water supply, and turn off fuel supply

valve.

3. After each use, wipe all surfaces with a clean,

damp cloth.

4. Perform regular maintenance. See maintenance

chart.

Maintenance

Perform regular maintenance at listed intervals to en-

sure maximum life and performance.

There are different break-in periods for engine, pump,

and gear reducer (if used). Follow each respective

break-in period as listed.

If operating pressure washer in dusty conditions, per-

form maintenance checks more frequently.

WARNING

To reduce risk of serious bodily injury, including

fluid injection, splashing in eyes or on skin or injury

from moving parts, always follow Pressure Relief

Procedure on page 6 before proceeding.
