When operating the HOTSY DB-3030, you must wear appropriate protective equipment to avoid injury.

Ear Protection: This machine exceeds 85 db, so appropriate ear protection must be worn.

Eye, Hand, and Foot Protection: High-pressure spray can cause paint chips or other particles to become airborne at high speeds. To avoid personal injury, eye, hand, and foot safety devices must be worn.

Always grip the cleaning wand securely with both hands before starting to prevent injury from a whipping wand.

Risk of Injection: The high pressure developed by the HOTSY DB-3030 will cause personal injury or equipment damage. Keep clear of the nozzle. Do not direct the discharge stream at people.

Protect from Freezing: It is important you protect the machine from freezing. Failure to do so could cause malfunction and damage. Follow storage instructions specified in the manual.

Electrical Hazard: Keep the wand, hose, and water spray away from electric wiring to prevent fatal electric shock. Do not spray water on or near electrical components.

Unstable Surfaces: Be extremely careful when using a ladder, scaffolding, or any other relatively unstable location. The cleaning area should have adequate slopes and drainage to reduce the possibility of a fall due to slippery surfaces.

Inlet Water: Inlet water must be clean fresh water and no hotter than 90°F.

Pump Operation: Never run the pump dry or leave the spray gun closed longer than 1-2 minutes.

The pneumatic tires on your HOTSY DB-3030 may not be fully inflated due to shipping and storage. Before use, please check and inflate the tires by following these steps:

a. Remove the valve cap from the tire.

b. Attach a bicycle pump and inflate the tire to a maximum pressure of 25 PSI. Note: If a compressor must be used, follow the compressor manufacturer’s guidelines to limit the output pressure so as not to exceed 25 PSI.

c. Replace the valve cap to the tire valve and tighten firmly. Tire pressure should not exceed 25 PSI.

Pump: Develops high pressure.

Starter Grip: Used for starting the engine manually.

Spray Gun: Controls the application of water and detergent with a trigger device. Includes a safety latch.

Detergent Injector: Allows you to siphon and mix detergents.

Wand: Must be connected to the spray gun.

High Pressure Hose: Connects one end to the water pump discharge nipple and the other end to the spray gun.

Pump Protector: Cycles fresh cool water through the pump when recirculating water reaches 140°F. If the trigger is released for more than 1-2 minutes, warm water will discharge from the pump protector onto the floor to prevent internal pump damage.

STEP 1: Attach the handle to the frame of the pressure washer. It may be necessary to move the handle supports from side to side to align it.

STEP 2: Insert the carriage bolt through the holes from the outside and attach a nut from the inside. Tighten nuts.

STEP 3: Attach the spray gun/hose storage handle and bracket to the main handle. Tighten nuts.

STEP 4: Attach the high pressure hose to the spray gun using teflon tape on the hose threads.

STEP 5: Attach the nozzle extension to the spray gun/wand. Tighten both by hand.

STEP 6: Pull the spring-loaded collar of the wand coupler back to insert your choice of pressure nozzle.

STEP 7: Release the coupler collar and push the nozzle in until the collar clicks. Pull the nozzle to ensure it is seated properly.

STEP 8: Connect the high pressure hose to the pump discharge nipple. Push the coupler collar forward until secure.

STEP 9: Connect a garden hose (7.5m) to a cold water source.

STEP 10: Check inlet filters, remove debris, then connect the garden hose to the pump water inlet. CAUTION: Do not run the pump without water, as pump damage will result.

STEP 1: Check engine oil level. It should be level with the bottom of the oil filler neck with the machine level. Change the oil after the first 5 hours of use, then every 50 hours.

STEP 2: Check the pump oil level. Use 30 wt. (non-detergent) oil.

STEP 3: Fill the gas tank with unleaded gasoline. Do not use leaded gasoline.

STEP 4: Squeeze the spray gun trigger to eliminate trapped air and wait for a steady flow of water to emerge from the spray nozzle.

STEP 5: Rotate the fuel shut-off valve to the “On” position.

STEP 6: Move the choke lever to the “Choke” position (for a warm engine, leave it in the run position).

STEP 8: Turn the engine switch to the “On” position.

STEP 9: Pull the starter grip. If the engine fails to start after 2 pulls, squeeze the trigger gun to release pressure and repeat. After the engine warms up, move the choke to the run position. CAUTION: Small engines may kick back. Do not hold the pull starter grip tightly in hand.

The HOTSY DB-3030 comes with four color-coded quick connect nozzles that provide a wide array of spray widths. Always engage the safety latch on the spray gun trigger before replacing nozzles.

White 40° or Green 25° Nozzle: Use for a more gentle rinse.

Yellow 15° Nozzle: Use to scour a surface.

Black Nozzle: Use to apply detergent.

STEP 1: Connect the detergent injector to the discharge nipple on the machine. Connect the high pressure hose to the injector with the quick coupler.

STEP 2: Use a detergent specifically designed for pressure washers. Prepare the solution as required and place the filter end of the detergent suction tube into the detergent container.

STEP 3: With the safety latch on the spray gun engaged, secure the black detergent nozzle into the quick coupler. Detergent cannot be applied using the yellow, green, or white nozzles.

STEP 4: With the engine running, pull the trigger to operate the machine. Apply detergent to the work area. Do not allow detergent to dry on the surface.

IMPORTANT: After each use, you must flush the detergent injection system by placing the suction tube into a bucket of clean water and running the pressure washer in low pressure for 1-2 minutes.

For best results when cleaning with your HOTSY DB-3030, follow these tips:

Pre-rinse: Pre-rinse the cleaning surface with fresh water.

Detergent Application: Apply detergent to the surface at low pressure. For best results, limit your work area to sections approximately 6 feet square and always apply detergent from the bottom to the top. Allow it to remain on the surface for 1-3 minutes but do not let it dry.

Rinsing: Rinse at high pressure from top to bottom in an even sweeping motion, keeping the spray nozzle approximately 1 foot from the cleaning surface. Use overlapping strokes.

Recommendations:

• Before cleaning any surface, test the spray pattern and distance on an inconspicuous area.

• If painted surfaces are peeling or chipping, use extreme caution as the pressure washer may remove loose paint.

• Keep the spray nozzle a safe distance from the surface you plan to clean. High-pressure wash a small area, then check for damage before continuing.

Using the wrong chemicals will harm the machine and damage the surface being cleaned. Never use the following with your HOTSY DB-3030:

• Bleach, chlorine products, and other corrosive chemicals

• Liquids containing solvents (e.g., paint thinner, gasoline, oils)

• Tri-sodium phosphate products

• Ammonia products

• Acid-based products

STEP 1: Flush the detergent system. Remove the detergent suction tube from its container and insert it into one gallon of fresh water. Pull the trigger on the spray gun and siphon water for one minute.

STEP 2: Turn off the engine.

STEP 3: Turn off the water supply.

STEP 4: Press the trigger to release water pressure.

STEP 5: Disconnect the garden hose from the water inlet on the machine.

STEP 6: Disconnect the high pressure hose from the pump discharge nipple.

STEP 7: Engage the spray gun safety lock.

CAUTION: Always store your HOTSY DB-3030 in a location where the temperature will not fall below 32°F (0°C). The pump is susceptible to permanent damage if frozen. FREEZE DAMAGE IS NOT COVERED BY WARRANTY.

1. Stop the pressure washer and squeeze the spray gun trigger to release pressure.

2. Detach the water supply hose and high pressure hose.

3. Turn on the machine for a few seconds until the remaining water exits. Turn the engine off immediately.

4. Drain the gas from the engine.

5. Do not allow the high pressure hose to become kinked.

6. Store the machine and accessories in a room that does not reach freezing temperatures.

For storage longer than one month, also perform engine maintenance such as replenishing engine oil and draining all gasoline.

Regular preventative maintenance will add many hours to the life of your HOTSY DB-3030 pressure washer. Perform maintenance more often under severe conditions.

NOTE: Read the engine manual for any maintenance or service questions.
