disengaged

3. Check oil level in pump. It should be half way up the sight glass, located on the front of the pump. Add pump oil as necessary. The system is equipped with a thermal overload to help prevent severe damage.

Oil level

ti5430a

After the first 50 hours of operation, drain and refill pump oil.

4. Turn on water supply.

ti5428a

• All Honda engine-powered pressure washers are equipped with an engine low-oil sensor that shuts the engine off when the oil level falls below a certain level.

• If the engine stops unexpectedly, check the oil and fuel levels.

• Check the oil level each time you add fuel.

2. Check fuel level.

Operation

7. Move switch to ON position and set throttle to HALF throttle position.

OFF

ti5434a

CAUTION

• Do not allow pressure washer to idle for more than 10 minutes. This causes the recirculating water to overheat and can seriously damage the pump.

• Turn off pressure washer if it will not be spraying at least every 10 minutes. If heated inlet water is used, reduce this time more.

• Do not operate pressure washer with inlet water screen removed. This screen help keep abrasive sediment out of pump. This sediment could clog pump or damage cylinders. Keep screen clean.

• Do not pump caustic materials which could corrode pump components.

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

• If engine is cold, before starting engine, close choke completely. In cool weather you might have to run engine for the first 10-30 seconds with the choke closed. In warm weather, open choke completely as soon as engine starts.

• If engine is warm, start engine with choke completely open or only partially closed. When engine starts, open choke completely.

Operation

3. Install black (large orifice) chemical tip (Installing and Changing Spray Tips, page 9).

The large orifice of the chemical tip causes a drop in pressure that actuates the chemical injector. Changing back to a small orifice 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 spraying. To regulate the flow rate of the chemical, turn the chemical adjustment knob on the injector.

ti5439a

Installing and Changing Spray Tips

Spray tips have 4- or 5-digit numbers on them. The first two digits are the spray angle.

Spray Tip No. Spray Pattern Fan Angle 00XXX 0° blaster (red) 15XXX 15° (yellow) 25XXX 25° (green) 40XXX 40° (white) Chemical* XX° (black)

*The chemical injector tip is brass and has a larger

opening and a black plastic cap.

1. Follow Pressure Relief Procedure, page 6.

2. Lock trigger safety.

3. Without holding your hand over the spray tip (A), pull back the quick coupler ring (B). Remove the current tip. Install a different tip. Push quick coupler ring back into place.

CAUTION

To avoid the high pressure blowing the o-ring out of the quick coupler, never operate the pressure washer without a tip securely mounted in the quick coupler.

Shutdown, Flushing and Storage

Short-term Storage (less than 30 days)

• Before you store the pressure washer overnight or transport it, disconnect the water supply and CLOSE the fuel supply valve.

ti5441a

• After each use, wipe all pressure washer surfaces with a clean, damp cloth.

Long-term (more than 30 days)/Winter Storage

• Do not store unit outside where it can be exposed to rain, dirt or adverse weather conditions.

• Do not expose pressure washer to freezing temperatures or allow water to freeze in pressure washer components which could cause the pump to lock-up. If this happens, allow the pump to thaw naturally in a WARM ENVIRONMENT. Do not attempt to speed up this process by pouring warm water on the pump. This could cause additional damage to the pump.

ENGINE:

1. Run engine until gas is gone or stabilize fuel and run it through fuel system and carburetor.

2. Drain water out of pressure washer hose.

3. Turn fuel system of OFF position.

PUMP:

With the exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.

In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the negligence of Graco, or otherwise.
