FUEL HAZARD:

Fuel is combustible. When spilled on a hot surface it can ignite and cause a fire.
Do not fill fuel tank while engine is running or hot.

EXHAUST HAZARD:
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Do not operate this
equipment in a closed building.

EQUIPMENT MISUSE HAZARD:
Misuse of pressure washer or accessories can cause the equipment to rupture or malfunction and
result in serious injury.

 Do not alter or modify any part or factory–setting
 Check equipment daily. Repair or replace worn or damaged parts immediately.
 Do not exceed maximum working pressure (MWPR) of the lowest–rated system component
 Use fluids and solvents that are compatible with the equipment wetted parts. See Specifications

page for this information.

 Wear hearing protection when operating this equipment.
 Do not “blow back” fluid; this is not an air spray system

 Follow Pressure Relief, page 7 before cleaning, checking or servicing equipment.

TOXIC FLUID HAZARD:

Hazardous fluid or toxi fumes can cause serious injury or death if splashed in eyes or on skin,
inhaled, or swallowed.

 Know specific hazards of fluids you are using and take protective measures as recommended by

the fluid and solvent manufacturer.

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.

 Fluid injected into skin might look like just a cut, but it is a serious injury. Get immediate

surgical treatment.

 Do not point gun at anyone or any part of the body.
 Do not stop or deflect leaks with hand, body, glove, or rag.
 Do not put your hand or fingers over the spray tip.
 TIghten fluid connections before you start this equipment.
 Engage the gun safety whenever you stop spraying.
 Follow Pressure Relief Procedure, page 7 if the spray tip clogs and before you clean, check

or service this equipment.

 Repair or replace worn or damaged parts immediately.
 Check hoses, tubes, and couplings daily. Do not repair high–pressure couplings. Replace entire

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

Installation

Connect High–Pressure Hose and Gun

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

Note: Adapter kit 249101 can be used to connect
two high pressure hoses together.

Install Spray Tip

Install spray tip on wand. Installing and Changing Spray Tips,
page 12). If you are using a Sandblasting Kit, see its separate
manual for installation instructions.

Connect to Water Supply

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

ti7345a

ti3228a

CAUTION

Before you connect garden hose to pres­sure washer, check local plumbing codes
regarding cross–connection to water
supply. If required, install backflow pre­venter.

If inlet water pressure is over 60 psi (4.1
bar), a regulating water valve must be
installed at garden hose connection.

Do not exceed 104° F (40° C) inlet water
temperature.

Note: Water source must have a minimum flow rate equal to that of pressure washer.

PRESSURE RELIEF

Follow these instructions whenever you are instructed to relieve pressure, stop spraying for

more than 10 minutes, check or service the equipment, or install or clean the spray nozzle.

1. Engage trigger safety latch

2. Turn pressure washer off

3. Remove ignition cable from spark plug.

TI3233A

4. Shut off water supply. Disconnect from water.

5. Disengage trigger safety latch. Trigger gun to relieve
pressure. Then re–engage the safety latch.

TI3234a

Note: If you suspect that the spray tip or hose is clogged or that pressure has not been fully relieved after

following the steps above, disengage the trigger safety latch and trigger the gun to relieve pressure.

Operation

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

 Always 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.

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

 If 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 wa­ter. Costly pump damage will result.
Always be sure water supply is complete­ly turned on before you run pressure
washer.

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.

6. For Model 2525LD ONLY, move
throttle to Rabbit (fast) position first.

All models

Model 2525 Only
For all models, (then) move choke to
CHOKE position.

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 pres­sure washer as a brace provides better leverage.

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

CAUTION

 Do 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.

 Turn 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.

 Do 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.

 Do not pump caustic materials.
