Frequently Asked Questions - 871SS Hotsy

What type of oil does the pump use?

The pump uses Hotsy pump oil (ISO 100 or equivalent non-detergent oil). Check your manual for specific viscosity.

Can I use bleach or other chemicals in the detergent tank?

Only use pressure washer-safe detergents. Bleach can damage seals and the pump. Rinse the system after use.

How do I winterize the pressure washer?

Drain all water from the pump, hoses, and coil. Use RV antifreeze or store in a heated area to prevent freezing damage.

The pressure is low, what should I check?

Check for clogged nozzles, air in the inlet line, or a worn pump seal. Ensure the water supply is sufficient and the inlet filter is clean.

What safety precautions should I take?

Always wear safety goggles and gloves. Never point the gun at people or pets. Engage the trigger lock when not in use.

How often should I change the pump oil?

Change the pump oil after the first 50 hours of use, then annually or every 500 hours, whichever comes first.

Can I use hot water from a tank?

This machine is designed to heat water internally. Do not feed hot water (above 100°F) into the inlet as it may damage the pump.

Why does the machine cycle on and off?

This is normal if you release the trigger. The automatic shut-off stops the motor to reduce wear. If it cycles while spraying, check for a faulty unloader valve.

What is the maximum inlet water temperature?

The maximum inlet water temperature is 100°F (38°C). Higher temperatures can damage the pump seals.

How do I replace the nozzle?

Turn off the machine, release pressure, and use a nozzle wrench to remove the old nozzle. Install the new one and tighten securely.

INSTALLATION INSTRUCTIONS

Getting Started

IMPORTANT: Proper initial installation of equipment will assure more satisfactory per for mance, longer service life, and lower main to nance cost.

IMPORTANT: The use of a backfl ow preventer on the water supply hose is recommended and may be required by local code.

The pressure washer should be run on a level sur face and in a protected area where it is not readily influenced by out side forces such as strong winds, freezing temp per a tures, rain, etc. The pressure washer should be located to assure easy access for fl lling of fl uids, adjustments and maintenance. Normal precautions should be taken by the op er a tor to pre vent moisture from reaching the pressure washer. It is rec om mend ed that a par ti tion be made between the wash area and the pressure washer to prevent di rect 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

DANGER: DO NOT run machine indoors or in an enclosed area, 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 or di nanc es. Consult local heating con trac tors.

If the pressure washer is to be used in an enclosed area, a fl ue must be installed to vent burner and en gine exhaust to the outside atmosphere. Be sure the fl ue is the same size as the burner exhaust vent on the pressure washer. See Figure 1 for location. Poor draft will cause the pressure wash er to soot and not operate properly. When selecting the location for in stal la tion, beware of poorly ventilated lo ca tions or areas where exhaust fans

may cause an in suf fi cient supply of oxygen. Proper combustion can only be ob tained when there is a suffi cient supply of oxygen avail able for the amount of fuel being burned. If it is necessary to install the machine in a poorly ven ti lat ed area, outside fresh air may have to be piped to the burner and a fan installed to bring suffi cient air into the machine. Locate the pressure washer so that the fl ue will be as straight as pos si ble and protrude through the roof at a proper height and location to provide adequate draft. This oil fi red pressure wash er must have a draft regulator installed in the fl ue (avail able from most heating contractors). A draft reg u la tor will permit prop er upward fl ow of exhaust fl ue gases.

In addition, the pressure washer should never be operated in an enclosed area where high ambient temperatures exist. High ambient temperatures (above 100°F) can cause engine oil failure and will greatly reduce the engine's performance.

Gasoline Engine

The gasoline engine is preset for operation at al ti tudes be low 1000 feet above sea level. If operated at higher al ti tudes, it may be necessary to install a high altitude main jet in the carburetor. Contact an au tho rized engine sales and service center for details.

Pre-Operation Check

☐ Pump Oil (SAE 30W non-detergent oil)
☐ Cold Water Supply (3.5 gpm • 5/8" • 20 psi)
☐ Hose, wand, nozzles (nozzle size per serial plate)
□ Water fi Iter (intact, nonrestrictive)
☐ Engine fuel (unleaded 86 or higher)
☐ Engine oil (SAE 10W40)
☐ Burner fuel (No. 1 or No.2 home heating fuel or diesel)

Oil Burner

Burner Air Adjustment: The oil burner on this machine is preset for operation at altitudes below 1000 feet. If operated at higher altitudes, it may be necessary to adjust the air shutter and air band setting. Adjust the air shutter for a #1 or #2 smoke spot on the Bacharach scale.

To adjust, start machine and turn burner ON. Loosen two locking screws found in the air shutter openings and close air shutter until black smoke appears from burner exhaust vent. Note air shutter 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.

Air Shutter Locking Screw

Figure 3 - Burner Adjustment

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, dis con tin ue use and readjust air bands.

NOTE: If a fl ue is installed, have a professional ser-vice man adjust your burner for a #1 or #2 smoke spot on the Bacharach scale.

OPERATION INSTRUCTIONS

To Clean

DANGER: DO NOT place hands or fingers in front of high pressure spray. Bodily injury may result.

The detergent injector valve operates by reducing the volume of water, thus a vacuum is achieved and detergent is drawn into the system. DO NOT reduce the water inlet flow so the pump cavitates due to water starvation. Operating a pump with insufficient water will damage the pump seals.

1. Insert detergent inlet line into container of mixed detergent.
2. Completely open detergent control knob located on the side of the de ter gent injector valve. Refer to Figure 5.

Figure 5 - Detergent Injector Valve

1. Start the detergent suction by rotating the water adjustment knob of the detergent injector valve. Refer to Figure 6. Turning the knob counterclockwise will pull de ter gent into the system. The flow may be ob served through the clear detergent line. Secure the knob po si tion with the knurled nut.
2. The side detergent control knob can now be adjusted to meter the desired amount of detergent.
3. Wash from the bottom to the top, using side to side motions. This washes away heavy dirt and allows the detergent to soak as you work toward the top.
4. Do not wash at a 90^ angle to the work (straight at it). This will allow water to splash back at you and reduces your cleaning power. Wash at a 30^ to 60^ angle to the work. This will allow the water to splash away from you and the water will wash the dirt away faster and easier.

5. Use the width of the spray pattern to wash in a wide path. Overlap spray paths for complete coverage washing from side to side, using slow, steady motions.

6. The nozzle should be 12" to 24" from work, closer for tough areas. Be careful on painted or delicate sur fac es, the pressure may damage surface if noz zle is too close.

7. Small parts should be washed in a basket so the presure does not push them away. Larger, light weight parts should be clamped down so the presure does not push them away.
8. Turn the side detergent control knob clockwise (CW) for detergent decrease. Wait for detergent to clear. Always rinse with cold water after using detergent. Rinse from the top to the bottom to prevent de ter gent from dripping onto a rinsed area. For the best results, con tact your Hotsy dealer to help you select the best de ter gent for your application.

To Stop

1. If detergents were used, draw clear water through the detergent inlet line to purge detergent. Failure to do so may clog detergent injector valve.
2. If burner was used, turn OFF burner switch and allow pump to run cold water through coil for several minutes.
3. Move throttle lever to idle position.
4. Turn engine ON/OFF switch to the OFF position.
5. Close fuel shutoff valve (if so equipped).
6. Turn water supply OFF.
7. Squeeze trigger of trigger gun to relieve system pressure.

STORAGE

DANGER: DO NOT store fl ammable liquids (gas o line, die sel fuel, solvents, etc.) near pressure wash er, or in non-ventilated areas.

Protect from freezing by storing in a heated area, or by flushing the system with antifreeze (use an au to motive engine antifreeze or windshield washer solvent to antifreeze). To flush the system with antifreeze, the following steps are to be followed:

1. Connect the water supply hose to the garden hose connector located on the pump. Turn on water supply.
2. Place the detergent inlet line into a container of antifreeze.
3. Hold wand firmly, release trigger of trigger gun.
4. Start engine. Place throttle lever in Full Throttle position.

During the break-in-period, make sure the oil is changed after the fi rst 40 hours of operation. After that, re place oil every 3 months or 500 hours of operation, which ev er comes fi rst.

Figure 7 - Pump Lubrication

Proper Pump Care:

• DO NOT pump acids.
• DO NOT allow pump to run dry.

• Winterize if storing in freezing temperatures, refer to Stor age 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 an ti freeze if storing for an extended period of time, refer to Storage for details.

Gasoline Engine

Refer to the provided Gasoline Engine Manual for rec om mend ed maintenance.

Relief Valve

WARNING: The relief valve on this pressure washer has been factory set and sealed and is a fi eld non-adjustable 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 Coil Outlet Assembly.

If pressure from pump or thermal expansion should exceed safe limits, the relief valve will open, allowing high pressure to be discharged through hose to ground. Caution: Inspect relief valve annually for any obstruction.

Unloader Valve

WARNING: The unloader valve on this pressure washer has been factory set and sealed and is a fi eld nonadjustable part. Tampering with the factory set ting may cause personal injury and/or property dam age, and will void the manufacturer warranty.

Burner Fuel Filter

Drain any water which has accumulated in fuel fi liter and clean or replace fi liter 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 com bus tion 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.

yHour Meter

This hour meter will monitor the total hours of operation of the pressure washer to signal when routine main te nance is required.
