3. Safety Information
WARNING: HIGH PRESSURE HAZARD
- DO NOT POINT AT HUMAN BODY: High-pressure spray can cause severe injury. Always direct the spray away from people, pets, and electrical components.
- EYE PROTECTION: Always wear appropriate eye protection (safety goggles) when operating the pressure washer.
- SECURE CONNECTIONS: Ensure all connections are securely fastened before starting the pressure washer to prevent leaks and accidental disconnections.
- STABLE FOOTING: Maintain stable footing and balance when operating the pressure washer, as the recoil force can be significant.
- CHILDREN AND PETS: Keep children and pets away from the operating area.
- ELECTRICAL SAFETY: Never spray water directly at electrical outlets, cords, or equipment.
- READ MANUAL: Always read and understand the pressure washer's main instruction manual before using this replacement trigger gun and lance.
4. Setup
Follow these steps to properly set up your new trigger gun and variable lance with your Lavor Superwash 160 pressure washer:
- Ensure Power Off: Before connecting any accessories, ensure your pressure washer is turned off and unplugged from the power source. Release any residual pressure by squeezing the trigger of the old gun.
- Disconnect Old Accessories: Carefully disconnect the existing trigger gun and lance from the high-pressure hose of your pressure washer.
- Connect New Trigger Gun: Attach the new replacement trigger gun to the high-pressure hose. Ensure the connection is tight and secure to prevent leaks under pressure.
- Attach Variable Lance: Connect the variable lance to the front end of the trigger gun. Twist or push until it clicks securely into place, depending on the connection type.
- Water Supply: Connect your pressure washer to a suitable water supply and ensure the water tap is fully open.
- Purge Air: Before turning on the pressure washer, squeeze the trigger of the new gun to allow water to flow through and purge any air from the system. Continue until a steady stream of water emerges.
5. Operating Instructions
Once set up, you can begin operating your pressure washer with the new trigger gun and lance:
- Start Pressure Washer: Plug in and turn on your Lavor Superwash 160 pressure washer.
- Engage Trigger: Point the lance away from yourself and others, then squeeze the trigger to begin spraying.
- Adjust Spray Pattern: The variable lance allows for spray pattern adjustment. Rotate the nozzle at the end of the lance to switch between a concentrated stream and a wider fan spray. Experiment to find the optimal pattern for your cleaning task.
- Trigger Lock: For extended use, engage the trigger lock mechanism (typically a small lever or button near the trigger) to maintain continuous spray without holding the trigger. Disengage the lock before releasing the trigger.
- Detergent Application (Low Pressure): To apply detergent, switch the lance to its low-pressure setting (usually the widest fan spray or a specific detergent nozzle setting). This setting reduces the pressure, allowing the pressure washer to draw detergent from its reservoir. Refer to your pressure washer's main manual for specific detergent application instructions.
- Shut Down: When finished, turn off the pressure washer, unplug it, and then squeeze the trigger to release any remaining pressure in the system before disconnecting the hose or lance.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your trigger gun and lance:
- Rinse After Use: After each use, flush the trigger gun and lance with clean water to remove any detergent residue or debris.
- Inspect Connections: Periodically check all connections for wear, damage, or leaks. Replace O-rings or seals if necessary.
- Clean Nozzle: If the spray pattern becomes irregular or weak, the nozzle may be clogged. Use a small wire or nozzle cleaning tool (often supplied with pressure washers) to clear any obstructions.
- Storage: Store the trigger gun and lance in a clean, dry place, protected from freezing temperatures. Disconnect them from the pressure washer for storage.
- Avoid Dropping: While durable, avoid dropping the unit, especially on hard surfaces, as this can damage internal components or the nozzle.
