When assembling, use teflon tape on all plumbing connections to prevent leakage.
Install high pressure hose on machine as shown in Figure 1.
IMPORTANT: Before installing pressure hose onto the trigger gun/wand assembly, turn on the water supplyand allow to run from the end of the hose until clear to prevent the nozzle from clogging.
Assemble pressure hose onto trigger gun/wand assembly as shown in Figure 2.
Make sure that all plumbing connections are tight.

INSTALLATION

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.

Venting

CAUTION: All venting must be in accordance with applicable federal and state laws, and local ordinances. 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. See Component Identification for location. 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 suf ficient 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 provided to 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.

Beckett Burner

To adjust: start machine and turn burner ON. Loosen two locking screws found in the air shutter openings (refer to figure 3 ) and close air shutter until black smoke appears from burner exhaust vent. Note air band position. Next, slowly open the air shutter until white smoke just starts to appear. Turn air shutter halfway back to the black smoke position previously noted. Tighten locking screws.

If the desired position cannot be obtained using only the air shutter, lock the air shutter in as close a position as can be obtained, then repeat the above procedure on the air band setting.
CAUTION: If white smoke appears from burner exhaust vent during start-up or operation, discontinue use and readjust air bands.
NOTE: If a flue is installed, have a professional serviceman adjust your burner for a #1 or #2 smoke spot on the Bacharach scale.
For additional burner component information, see Burner Assembly. It is recommended that the oil burner be serviced yearly or as needed. Contact your local service center.

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 thinners, 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 with antifreeze, attach a short length of hose to the garden hose connectorlocated on the pump. Place the other end of the hose into a container of antifreeze. Start machine and allow to run until antifreeze flows from the end of the wand.
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 anti-freezing, disconnect the pressure hose from machine and remove the coil drain plug (refer to Component Identification 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.

Maintenance

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 the full mark on the dipstick or to center of sight glass window found on the side of the pump, refer to Figure 6. 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, whichever comes first.

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 & Maintenance for details.

Pump Motor

On a yearly basis, oil pump motor per instructions on motor nameplate.

Relief Valve

If pressure from pump or thermal expansion should exceed safe limits, the relief valvek will opent, allowing high pressure to be discharged through hose to ground.

Caution: Inspect relief valve annually for any obstruction.

Unloader Valve/ Relief Valve

WARNING: The unloader valve and relief valve on this pressure washer have been factory set and sealed and are a field nonadjustable part. Tampering with the factory setting may cause personal injury and/ or property damage, and will void the manufacturer warranty. For replacement parts refer to Pump Assembly.

Burner Fuel Filter
