Frequently Asked Questions - AW150 HITACHI
How do I start the Hitachi AW150 pressure washer?
Ensure the water supply is connected and the power cord is plugged in. Turn the power switch to ON. Unlock the trigger gun by pressing the safety lock. Squeeze the trigger to start the water flow.
How do I use the detergent function?
Fill the detergent tank with a suitable cleaning solution. Attach the low-pressure nozzle or adjust the spray lance to low pressure. Activate the detergent suction by pulling the detergent knob (if equipped). Apply detergent to the surface, let it soak, then rinse by switching to high pressure.
Why is the pressure washer not producing high pressure?
Check if the water supply is sufficient (minimum 10 L/min). Ensure the inlet filter is clean. Verify that the nozzle is not clogged. Inspect for air leaks in the hose connections. If using a low-pressure nozzle, switch to a high-pressure lance.
How often should I maintain the pressure washer?
After each use, flush the system with clean water and clean the inlet filter. Check the pump oil level every 50 hours of use; change oil annually. Inspect the hose and connections for damage. Store the unit in a frost-free environment.
Can I use hot water with the AW150?
No, this pressure washer is designed for cold water only (max 40°C). Using hot water may damage the pump and seals.
What type of detergent can I use?
Use only detergents specifically designed for pressure washers. Avoid corrosive or flammable liquids. Dilute according to the manufacturer's instructions.
How do I store the pressure washer in winter?
Drain all water from the pump, hose, and detergent tank. Store in a dry, frost-free area. If temperatures drop below freezing, add antifreeze suitable for pressure washers (non-toxic).
What is the warranty period for the Hitachi AW150?
Hitachi typically offers a 2-year warranty for household use. Commercial use may have a shorter warranty. Check the warranty card for details.
How do I replace the pump oil?
Use a 15W-40 or SAE 30 non-detergent oil. Drain old oil from the oil plug, refill to the correct level (usually 0.2 L). Do not overfill. Refer to the manual for oil type and capacity.
Where can I get spare parts for the AW150?
Contact Hitachi service centers or authorized dealers. Parts such as nozzles, hoses, and trigger guns can be ordered online. Use the model number AW150 for correct parts.
