Getting Started 

IMPORTANT: Proper initial installation of equipment 

will assure more satisfactory performance, longer service 

life, and lower maintenance cost. 

IMPORTANT: The use of a backflow preventer on the 

water supply hose is recommended and may be 

required by local code. 

The pressure washer should be run on a level surface 

and in a protected area where it is not readily influenced 

by outside forces such as strong winds, freezing 

temperatures, rain, etc. The pressure washer should be 

located to assure easy access for filling of fluids, 

adjustments and maintenance. Normal precautions should 

be taken by the operator to prevent moisture from reaching 

the pressure washer. It is recommended that a partition 

be made between the wash area and the pressure washer 

to prevent direct spray from the wand from coming in 

contact with the pressure washer. Moisture reaching the 

equipment will reduce the pressure washer’s service life. 

All installations must comply with the local codes covering 

such installations. 

Electrical 

WARNING: Make sure all switches and controls are in 

the OFF position prior to connecting electrical supply. 

WARNING: DO NOT stand in water while connecting 

and disconnecting electrical supply. 

IMPORTANT: Consult local building codes for exact 

electrical requirements. Licensed contractors may be 

required. 

Power In 

Figure 5 - Wiring Connections 

INSTALLATION INSTRUCTIONS 

The 5700 Series is designed for connection to an overload 

protected grounded circuit. It is recommended this circuit 

be protected by a UL approved ground fault circuit 

interrupter (GFCI). An electrical disconnect must be 

provided in this circuit. All wiring must be of proper voltage 

and amperage rating and conform to applicable codes. 

Refer to Figure 5 for wiring connections. A hole has been 

provided in the control box for attachment of 1 inch 

electrical conduit. 

For proper operation the motor rotation is to be 

counterclockwise as viewed looking towards the rear of 

the motor (opposite pump attachment). If the rotation is 

incorrect, interchange any two of the power supply 

connections to reverse rotation. 

Venting 

DANGER: DO NOT run machine indoors or in an 

enclosed area without proper ventilation, as exhaust 

fumes may be hazardous to your health. 

DANGER: DO NOT operate machine in areas where 

flammable vapors (gasoline, solvents, etc.) may be 

present, as this machine may ignite the vapors. 

CAUTION: All venting must be in accordance with 

applicable federal and state laws, and local ordinances. 

This machine is not to be connected to a type B gas 

vent. Consult local heating contractors. 

If the pressure washer is to be used in an enclosed area, 

a flue must be installed to vent burner exhaust to the 

outside atmosphere. Be sure the flue is the same size as 

the burner exhaust vent on the pressure washer lid. Poor 

draft will cause the pressure washer to soot and not 

operate properly. When selecting the location for 

installation, beware of poorly ventilated locations or areas 

where exhaust fans may cause an insufficient supply of 

oxygen. Proper combustion can only be obtained when 

there is a sufficient supply of oxygen available for the 

amount of fuel being burned. If it is necessary to install 

the machine in a poorly ventilated area, outside fresh air 

may have to be piped to the burner and a fan installed to 

bring sufficient air into the machine. Locate the pressure 

washer so that the flue will be as straight as possible and 

protrude through the roof at a proper height and location 

to provide adequate draft. This oil fired pressure washer 

must have a draft regulator installed in the flue (available 

from most heating contractors). A draft regulator will permit 

proper upward flow of exhaust flue gases. 

Oil Burner 

Burner Air Adjustment: The oil burner is preset and 

performance tested at the factory (elevation 500 feet). A 

onetime initial correction of the burner for your location 

will pay off in economy, performance, and extended 

service life. 

To adjust, start machine and turn burner ON (refer to 

Operation for details). Loosen locking screw (refer to 

Figure 6) and close air band until black smoke appears 

from burner exhaust vent. Note air band position. Next,

GENERAL CLEANING TECHNIQUES & STORAGE 

CLEANING TECHNIQUES 

Pre-rinse cleaning surface with fresh water. Place detergent 

suction tube directly into cleaning solution and 

apply to surface at low pressure (for best results, limit 

your work area to sections approximately 6 feet square 

and always apply detergent from bottom to top). Allow 

detergent to remain on surface 1-3 minutes. Do not 

allow detergent to dry on surface. If surface appears to 

be drying, simply wet down surface with fresh water. If 

needed, use brush to remove stubborn dirt. Rinse at 

high pressure from top to bottom in an even sweeping 

motion keeping the spray nozzle approximately 1 foot 

from cleaning surface. Use overlapping strokes as you 

clean and rinse any surface. For best surface cleaning 

action spray at a slight angle. 

Recommendations: 

• Before cleaning any surface, an inconspicuous 

area should be cleaned to test spray pattern and 

distance for maximum cleaning results. 

• If painted surfaces are peeling or chipping, use 

extreme caution as pressure washer may remove 

the loose paint from the surface. 

• Keep the spray nozzle a safe distance from the surface 

you plan to clean. High pressure wash a small 

area, then check the surface for damage. If no damage 

is found, continue to pressure washing. 

CAUTION - Never use: 

• Bleach, chlorine products and other corrosive 

chemicals 

• Liquids containing solvents (i.e., paint thinner, 

gasoline, oils) 

• Tri-sodium phosphate products 

• Ammonia products 

• Acid-based products 

These chemicals will harm the machine and will damage 

the surface being cleaned. 


RINSING 

It will take a few seconds for the detergent to clear. 

Apply safety latch to spray gun. Select and install desired 

high pressure nozzle. NOTE: You can also stop 

detergent from flowing by removing detergent siphon 

tube from bottle. 

STORAGE 

DANGER: DO NOT store flammable liquids (gasoline, 

diesel fuel, solvents, etc.) near pressure washer, or 

in non-ventilated areas. 

Protect from freezing by storing in a heated area, or by 

flushing the system with antifreeze (use an automotive 

engine antifreeze or windshield washer solvent to 

antifreeze). To flush the system fill the float tank with 

antifreeze and remove pressure nozzle from wand. Start 

the machine and allow it to run until antifreeze flows from 

the end of the wand. Place end of wand into float tank 

and circulate the antifreeze through system for several 

minutes. Squeeze and release the trigger of the trigger 

gun several times to antifreeze the unloader system. Also 

draw antifreeze through the detergent inlet line to 

antifreeze the detergent system. For added protection 

after antifreezing, disconnect the pressure hose from 

machine and remove the coil drain plug (refer to Figure 

12 Item 15 for location). After coil has drained, replace 

pressure hose and coil drain plug. If the pressure washer 

is not to be used for an extended length of time, it is 

recommended that the system be flushed with antifreeze 

for rust protection.

WARNING: Unauthorized machine modification or 

use of non-approved replacement parts may cause 

personal injury and/or property damage and will 

void the manufacturer warranty. 

Pump 

Lubrication: To lubricate pump, use 30W non-detergent 

oil for pump crankcase. Crankcase must be filled to 

center of sight glass window found on the rear of the 

pump, refer to Figure 9. During the break-in-period, 

make sure the oil is changed after the first 25 hours of 

operation. After that, replace oil every 3 months or 300 

hours of operation, whichever comes first. 

Sight Glass 

Figure 9 - Pump Lubrication 

Proper Pump Care: 

DO NOT pump acids. 

DO NOT allow pump to run dry. 

Winterize if storing in freezing temperatures, refer 

to Storage for details. 

Use a water softener on the water system if known 

to be high in mineral content. 

Use only high quality detergents and follow manufacturer’s 

mix recommendations. 

Flush the system with clear water immediately 

after using detergent solutions. 

Clean filter screen on detergent inlet line periodically. 

Flush the pressure washer system with antifreeze 

if storing for an extended period of time, refer to 

Storage to details. 

Pump Motor 

Oil Fill 

Inspect the pump motor at regular intervals. The exterior 

of the motor should be kept free of dirt, oil, grease, 

water, etc. Keep all ventilation openings free from debris. 

If the motor is equipped with grease fittings, lubricate 

the motor after every 1000 hours of operation with 

Chevron SRI #2 lubricant or equivalent. If the motor is 

not equipped with grease fittings, the pump motor 

bearings are permanently lubricated and will not require 

any additional lubrication.

Burner Fuel Filter (Oil fired models only) 

Drain any water which has accumulated in fuel filter 

and clean or replace filter element as needed. 

Heating Coil 

Coil Descaling: In hard water areas, scale buildup within 

the heating coil will occur. Scale deposits will decrease 

the water temperature rise and may eventually clog the 

heating coil. Contact your local service center when 

descaling is needed. 

Coil Desooting: Poor grades of fuel oil or inadequate 

combustion air will cause heavy soot buildup on the 

outside surface of the heating coil. These deposits will 

insulate the coil. This will restrict the air flow through the 

coil, further aggravating the soot buildup. Contact your 

local service center when desooting is needed.
