Frequently Asked Questions - 852 Hotsy

What oil type does the Hotsy 852 require?

The Hotsy 852 uses SAE 30 non-detergent oil in the pump. For the engine, refer to the engine manual; typically SAE 10W-30 for gasoline engines. Always check the oil dipstick before use.

How do I winterize my Hotsy 852 pressure washer?

To prevent freeze damage, drain all water from the pump, hoses, and coils. Use a pump saver antifreeze or RV antifreeze. Remove the inlet filter, run the engine until it stalls, and store in a dry place.

What is the correct nozzle for general cleaning?

For general cleaning, use the 25° or 40° nozzle. The 0° and 15° are high-pressure for tough stains. Always test on a small area first.

Why is my Hotsy 852 not building pressure?

Common causes: clogged inlet filter, worn pump seals, air in the system, or a damaged unloader valve. Check the inlet screen, prime the pump, and inspect the pump oil.

Can I use bleach with this pressure washer?

Yes, the Hotsy 852 has a chemical injection system. Use a diluted bleach solution (1:10) and flush the system with fresh water afterward to prevent corrosion.

How often should I change the pump oil?

Change the pump oil after the first 50 hours, then every 500 hours or annually. Use SAE 30 non-detergent oil. Check the oil level before each use.

What size generator do I need if using electric start?

The Hotsy 852 is typically gas-powered without electric start. If your model has an electric starter (rare), a 5000-watt generator is recommended for the starting current.

How do I replace the spray gun?

Turn off the machine, relieve pressure. Unscrew the hose fitting from the old gun. Attach the new gun with Teflon tape on threads. Use a wrench to tighten, but avoid overtightening.

What is the maximum inlet water temperature?

The Hotsy 852 is a hot water machine, so inlet water can be up to 180°F (82°C). For cold water models, do not exceed 120°F to avoid pump damage.

Where is the model number located?

The model number is on a metal tag attached to the frame, near the pump or engine. Look for a serial number and model like '852'.

INSTALLATION INSTRUCTIONS

Venting

CAUTION - RISK OF ASPHYXIATION: Do not run machine indoors or in an enclosed area without the required venting, as exhaust fumes may be hazardous to your health.

CAUTION: All venting must be in accordance with applicable federal and state laws, and local ordinances. Consult local heating contractors.

IMPORTANT: A draft regulator shall be installed. INSTALLER UNE HOTTE DE TIRAGE.

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. Exhaust gases should not be vented into a wall, a ceiling, or a concealed space of a building. Be sure the flue is the same size as the burner exhaust vent on the pressure washer. 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 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.

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 band setting. Adjust air band for a #1 or #2 smoke spot on the Bacharach scale. If a smoky or eye-burning exhaust is being emitted from the stack, two things should be checked. First, check the fuel to be certain that kerosene or No.1 home heating fuel is being used. Next, check the air adjustment on the burner. An oily, smoky fire indicates a lack of air and the air band should be moved to allow the air to flow through the burner. Sharp eye-burning fumes indicate too much air flowing through the combustion chamber. The air band should be readjusted to allow less air to flow through the burner.

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 Exploded View page. It is recommended that the oil burner be serviced yearly or as needed. Contact your local service center.

Hotsy Crossfire Burner Air Adjustment

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

Water Supply

Connect water supply hose to water inlet. The water faucet and supply hose must be capable of providing a minimum of 4.0 gallons per minute (GPM) and a maximum pressure of 65 psi.

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.

WARNING: Always disconnect power before servicing your pressure washer.

IMPORTANT: Consult local building codes for exact electrical requirements. Licensed contractors may be required.

IMPORTANT: This machine must be electrically grounded. LA MACHINE DOIT ÊTRE MISE À LA TERRE.

OPERATION INSTRUCTIONS

To Clean

1. Insert detergent inlet line into container of mixed detergent. Open detergent ON/OFF valve. The detergent will be pulled automatically into the system. Allow detergent to reach end of wand before proceeding to step 3.
2. Select pressure nozzle with spray pattern that matches your cleaning needs. Engage manual trigger lock and install selected nozzle.
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. Wash 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 surfaces, the pressure may damage surface if nozzle is too close.
7. Small parts should be washed in a basket so the pressure does not push them away. Larger, light weight parts should be clamped down so the pressure does not push them away.
8. Close the detergent ON/OFF valve to permit rinse. Always rinse with cold water after using detergents. Rinse from the top to the bottom to prevent detergent from dripping onto a rinsed area. For the best results, contact your Hotsy dealer to help you select the best detergent for your application.

STEP 4: For hot water, turn the thermostat knob to 210° then push the burner switch to ON when a steady stream of water flows out of the spray gun. Burner will now light automatically. NOTE: Do not start machine with burner switch on.

STEP 5: For steam, open the steam valve counterclockwise. This lowers the pressure and raises the temperature.

STEP 6: The four color-coded quick connect nozzles provide a wide array of spray widths from 0^ to 40^ and are easily accessible when placed in the convenient rubber nozzle holder, which is provided on the front of the machine. NOTE: For a more gentle rinse, select the white 40^ nozzle. To scour the surface, select the yellow 15^ or red 0^ nozzle.

DETERGENTS & GENERAL WASHING TECHNIQUES

WARNING: Some detergents may be harmful if inhaled or ingested, causing severe nausea, fainting or poisoning. The harmful elements may cause property damage or severe injury.

STEP 1: Use detergent designed specifically for pressure washers. Household detergents could damage the pump. Prepare detergent solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the filter end of detergent suction tube into the detergent container.

STEP 2: With the engine running, pull trigger to operate machine. Liquid detergent is drawn into the machine and mixed with water. Apply detergent to work area. Do not allow detergent to dry on surface.

IMPORTANT: You must flush the detergent after each use by placing the suction tube into a bucket of clean water, open detergent valves then run the pressure washer for 1-2 minutes.

THERMAL PUMP PROTECTION

If you run your pressure washer for 3-5 minutes without pressing the trigger on the spray gun, circulating water in the pump can reach high temperatures. When the water reaches this temperature, the pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal device prevents internal damage to the pump.

CLEANING TIPS

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 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 and close detergent valve. Select and install the desired high pressure nozzle.

SHUT DOWN AND CLEAN-UP

STEP 1: Remove detergent suction tube from container and insert into one gallon of fresh water. Open detergent valve, pull trigger on spray gun and siphon water for one minute.

STEP 2: Turn thermostat adjust knob off and continue spraying, allowing the water to cool to below 100°.

STEP 3: Turn pump switch off.

STEP 4: Turn off water supply.

STEP 5: Squeeze trigger on spray gun to relieve remaining pressure.

STORAGE

CAUTION: Always store your pressure washer in a location where the temperature will not fall below 32^ F ( 0^ C). The pump in this machine is susceptible to permanent damage if frozen. FREEZE DAMAGE IS NOT COVERED BY WARRANTY.

1. Stop the pressure washer, squeeze spray gun trigger to release pressure.
2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately.
4. Drain the fuel and oil from the engine.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room which does not reach freezing temperatures.

CAUTION: Failure to follow the above directions will result in damage to your pressure washer.

When the pressure washer is not being operated or is being stored for more than one month, follow these instructions:

1. Replenish engine oil to upper level.
2. Drain diesel from fuel tank, fuel line, fuel valve and carburetor.
3. Cover the pressure washer and store in a clean, dry place that is well ventilated away from open flame or sparks.

After Extended Storage

CAUTION: Prior to restarting, thaw out any possible ice from pressure washer hoses, spray gun or wand.

DANGER: Do not store flammable liquids (gasoline, fuel oil, petroleum, solvents, etc.) near pressure washer, or in non-ventilated areas.

IMPORTANT: Machine must be stored indoors.

1. 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 runs from the end of the wand. Place wand into float tank and circulate the solution through system for several minutes. Open and close the trigger gun several times to circulate antifreeze through the unloader valve 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. 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.

IMPORTANT: Machine must be stored indoors.

Pump

Use Hotsy Pump Oil P/N 315068 or equivalent 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 rear of the pump. 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.

89212060-26

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 manu-facturer'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 for details.

Pump Motor

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

NOTE: Some motors may be equipped with permanently lubricated bearings and will not require additional lubrication.

Relief Valve

WARNING: The relief valve on this pressure washer has been factory set and sealed and is a field nonadjustable part. Tampering with the factory setting may cause personal injury and/or property damage, and will void the manufacturer warranty.

Unloader Valve

WARNING: The unloader valve on this pressure washer has been factory set and sealed and is 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 refer to Pump Assembly page.

Burner Fuel Filter

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.

Brake

Every 50 hours inspect brake components for proper operation. Repair or replace if needed.
