3.2 Water Intake and Hose

The 16.4-foot hose can draw water from multiple sources:

• Standard garden faucet (with appropriate adapter, if needed).
• Buckets, pools, or rivers.
• The hose includes a built-in filter to remove particles, leaves, and sludge from the water source.

3.3 Battery System

The unit operates on two included 21V 3.0Ah lithium-ion batteries.

• Insert a charged battery into the compartment on the pressure washer gun.
• The second battery serves as a spare for extended cleaning sessions.
• Fully charge both batteries before first use.

3.4 Foam Cannon

An attachment for applying car wash soap or cleaning detergent as a thick foam.

4. Use Guide

4.1 Before First Use

1. Unpack all components and inspect for damage.
2. Fully charge both included batteries using the provided charger.
3. Note: A small amount of residual moisture inside the unit from factory testing is normal and not a safety concern.

4.2 Assembly

1. Connect the Hose: Attach one end of the 16.4-foot hose to the water inlet on the pressure washer gun. Hand-tighten securely.
2. Attach the Nozzle: Ensure the 6-in-1 nozzle is securely attached to the end of the gun wand.
3. Insert the Battery: Slide a fully charged battery into the battery compartment on the gun until it clicks into place.
4. Connect Water Source: Attach the other end of the hose to your water source (faucet, or place the intake filter into a bucket/pool). Ensure the built-in filter is clean.

4.3 Operation

1. Turn on your water source. Ensure water is flowing through the hose to prime the pump.
2. Point the nozzle in a safe direction.
3. Squeeze the trigger on the gun to start the pressure washer. The motor will engage and pressurize the water stream.
4. Rotate the nozzle tip to select the desired spray pattern for your task.
5. For best results, hold the nozzle 6-12 inches from the surface and move in a steady, sweeping motion.
6. Release the trigger to stop the water flow and motor.

4.4 Using the Foam Cannon

1. Fill the foam cannon bottle with car wash soap or a compatible detergent diluted according to the product's instructions.
2. Attach the foam cannon to the end of the gun wand in place of the 6-in-1 nozzle.
3. With the pressure washer running, use the direct spray setting to generate thick foam.
4. Apply foam to the vehicle or surface, let it dwell, then rinse using an appropriate fan spray setting on the 6-in-1 nozzle.

4.5 Battery Management and Run Time

• With two fully charged 3.0Ah batteries, you can expect up to 90 minutes of continuous cleaning.
• This is sufficient to clean approximately two full-size SUVs or a 538 sq ft (50 m²) patio.
• When the first battery is depleted, press the battery release button, remove it, and insert the second charged battery.
• Recharge depleted batteries promptly.

4.6 After Use

1. Turn off the water source.
2. Squeeze the trigger to release any remaining pressure in the system.
3. Disconnect the hose from the water source and from the gun.
4. Remove the battery from the gun.
5. Drain any remaining water from the hose and gun by holding the unit upright and triggering it briefly in a safe area.
6. Wipe down the unit and store all components in the provided carry case in a dry place.

5. Safety and Maintenance

• Water Source: Only use clean water. The built-in filter helps but cannot purify contaminated water. Do not use hot water.
• Surface Testing: Always test the pressure washer on an inconspicuous area first, especially on delicate surfaces like wood siding or car paint.
• Battery Care: Use only the provided charger and batteries. Do not expose batteries to fire or extreme heat. Store batteries in a cool, dry place.
• Freeze Protection: Do not allow water to freeze inside the pump. Store the unit indoors in freezing temperatures.
• Cleaning: Keep the water inlet filter clean. Rinse the unit with clean water after use if it has been used with soap or in dirty conditions.
• Inspection: Regularly inspect the hose and connections for wear or leaks before use.

6. Troubleshooting

• Unit does not start: Ensure the battery is fully charged and correctly inserted. Check that the water source is on and water is flowing to the unit.
• Low pressure or pulsating stream: Check for kinks in the hose. Ensure the water inlet filter is not clogged. The water source may have insufficient flow; try a different source.
• Battery drains quickly: This is normal when using high-pressure settings (0° or 15° nozzle). Switch to a wider fan pattern for less demanding tasks to conserve battery. Ensure batteries are fully charged before use.
• Water leaking from connections: Ensure all hose connections are hand-tightened securely. Inspect O-rings for damage.
