Pump: Develops high pressure.

Starter Grip: Used for starting the engine manually.

Spray Gun: Controls the application of water and detergent onto the cleaning surface 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 to prevent internal pump damage. Water may leak from this valve if the trigger is released for more than 1-2 minutes.

Pressure Nozzle: Attaches to the wand to control the spray pattern.

Inlet Screen: Filters water coming into the pump.

Unloader: A component that regulates pressure.

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 the handle so it will slide over the frame supports.

Step 2: Insert the carriage bolt through the holes from the outside of the unit and attach a nut from the inside of the machine. Tighten nuts.

Step 3: Attach the spray gun/hose storage handle and bracket to the 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 until the collar clicks. Pull the nozzle to make sure 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 to the cold water source.

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

Step 1: Check the engine oil level. The oil level should be level with the bottom of the oil filler neck. Be sure the machine is level. Change the oil after the first 5 hours of use, then every 50 hours. Do not run the engine with high or low oil levels.

Step 2: Check the pump oil level by using the dipstick or observing the oil window (if equipped). Use 30 wt. (non-detergent) oil.

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

Step 4: Trigger the spray gun to eliminate trapped air, then 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. Slide the fuel valve lever to the “ON” position.

Step 6: Move the choke lever to the “Choke” position. For a warm engine, leave the choke lever in the run position. Move the choke lever to the “Closed” position. To restart a warm engine, leave the choke lever in the “Open” 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 the step. Return the starter gently. After the engine warms up enough to run smoothly, move the choke to the run position.

The four color-coded quick connect nozzles for the HOTSY DB-2324 provide a wide array of spray widths and are easily accessible from the rubber nozzle holder on the front of the machine. Never replace nozzles without engaging the safety latch on the spray gun trigger.

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

Yellow 15° Nozzle: Use to scour a surface.

Black (Soap) 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 designed specifically 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: You must flush the detergent injection system after each use by placing the suction tube into a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.

For best results with your HOTSY DB-2324, follow these tips:

Pre-rinse the cleaning surface with fresh water. Apply detergent at low pressure from the bottom up, limiting your work area to sections approximately 6 feet square. Allow detergent to remain on the surface for 1-3 minutes but do not let it dry. If it starts to dry, wet it down with fresh water. If needed, use a brush to remove stubborn dirt. Rinse at high pressure from the 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 for maximum cleaning results.

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

• 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.

Never use the following chemicals in your HOTSY DB-2324, as they will harm the machine and damage the surface being cleaned:

• 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

If you run the engine on your HOTSY DB-2324 for 1-2 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.

Step 1: Remove the detergent suction tube from the container and insert it into one gallon of fresh water. Slide the nozzle forward for low pressure or connect the black detergent nozzle. 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.

Always store your HOTSY DB-2324 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 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 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 which does not reach freezing temperatures.

When storing for more than one month, follow these instructions for engine maintenance:

1. Replenish engine oil to the upper level.

2. Drain gasoline from the fuel tank, fuel line, fuel valve, and carburetor.

3. Pour about one teaspoon of engine oil through the spark plug hole, pull the starter grip several times and replace the plug. Then pull the starter grip slowly until you feel increased pressure which indicates the piston is on its compression stroke and leave it in that position. This closes both the intake and exhaust valves to prevent rusting of the cylinder.

4. Cover the pressure washer and store in a clean, dry place that is well ventilated away from open flame or sparks.
