HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY

FOR PROFESSIONAL USE ONLY OBSERVE ALL WARNINGS.

Read and understand all instruction manuals before operating equipment.

FLUID INJECTION HAZARD

WARNING

General Safety

This pressure washer generates very high fluid pressure. Spray from the gun, leaks or ruptured components can inject fluid through your skin and into your body and cause extremely serious bodily injury including the need for amputation. Also, fluid injected or splashed into the eyes or on the skin can cause serious damage.

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including fluid injection and splashing in the eyes, or on the skin, always follow this procedure whenever you stop spraying for more than 10 minutes, when shutting down, and before checking or repairing any part of the system.

Engage the trigger safety latch.

Turn the sprayer off.

Disconnect the electrical supply.

Shut off the water supply.

Spray Gun Safety Devices

Be sure all gun safety devices are operating properly before each use. Do not remove or modify any pan of

the gun; this can cause a malfunction and result in

serious bodily injury.

NOTE TO PHYSICIAN: Injection in the skin is a ffaumafic injury. It is important to treat the injury surgically as soon as possible. Do not delay treatment to research toxicity. Toxicity is a concern with some exotic coatings injected

directly into the bloodstream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.

SAFER LATCH: Whenever you stop spraying for a moment, always set the gun safety latch in the engaged or “safe” position, making the gun inoperative. Failure to properly set the safety latch can result in accidental triggering of the gun.

SPRAY TIP SAFETY: Use extreme caution when cleaning or changing spray tips. If a spray tip clogs while spraying, immediately. ALWAYS follow the

GROUNDING INSTRUCTIONS

This product must be grounded. If it should malfunction

or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This equipment is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and

ordinances.

I DANGER

Improper connection of the equipment- grounding conductor can result in the risk of electrocution. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet installed by a qualified

GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (826)

The 826 pressure washer is provided with a ground-fault circuit-interrupter (GFCI) built into the

power supply cord. This device provides additional protection from the risk of electric shock. Should replacement of the cord become necessary, use only identical replacement parts that include GFCI protection.

DO NOT use the switch on the GFCI cord to start the unit. This may cause premature failure of the

GFCI.

ALWAYS

before resetting the GFCI.

turn the machine off at the switch

GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (1235)

To comply with me National Electrical Code (NFPA 70)

and to provide additional protection from the risk of

electric shock, connect the 1235 pressure washer to a

receptacle that is protected by a ground-fault circuit-interrupter (GFCI).

CAUTION

EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole cord connectors that accept the plug from the product. Use only extension cords that are intended for outdoor use. These extension cords are identified by a marking “Acceptable for use with outdoor appliances; store indoors while not

in use.” Use only extension cords having an electrical rating not less than the rating of the product. Do not use damaged extension cords. Examine extension cord before using and replace if damaged. Do not abuse extension cord and do not yank or pull on any cord to

disconnect. Keep cord away from heat and sharp edges. Always disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.

I- WARNING -1

To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch plug with wet hands.

General Safety

Any misuse of the pressure washer or accessories,

such as overpressurizing, modifying parts, using incompatible chemicals and fluids, or using worn or damaged parts, can cause them to rupture and result in

immediately.

Set Up

Before plugging in the unit, be sure the electrical service matches the specification in Technical Data (inside back cover) and the voltage label on the unit. With the

unit off, plug the power supply cord into a grounded,

GFCI-protected outlet. Do not remove the electrical

plug which comes with the unit or bend connecting

prongs to fit an improper outlet! Use an extension cord that meets the requirements of the EXTENSlON CORD

section and is no more than 100 ft (30 m) long. Added

length of cord will affect current draw of unit.

Connect the high pressure hose between the pump

outlet and the gun inlet.

CAUTION

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

Connect to Water Supply

CAUTION

Before attaching to the water supply, check your local plumbing code regarding cross- connection

to the water supply.

A backflow preventer P/N 801-133 is available to

prevent backflow of contaminated water into the

fresh water supply. Install it upstream from the

pump.

Install a regulating water valve, P/N 800-258, if inlet water pressure is over 60 psi (4.1 bar).

Do not exceed 160” F (70” C) inlet water

temperature.

Connect a hose with at least a 3/4 inch (19 mm) ID and not longer than 50 ft (15 m) to the unit’s 3/4 inch garden hose inlet.

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).
