Frequently Asked Questions - GRM1010 Ferm
What type of oil does the pump require?
The pump is pre-filled with high-pressure pump oil. For occasional maintenance, use a quality oil such as SAE 30 non-detergent oil. Check the manual for replacement intervals.
Can I use the pressure washer with a garden hose?
Yes, connect a standard garden hose with a compatible connector to the water inlet. Ensure the water supply flow rate is at least 450 L/h for optimal performance.
How do I start the pressure washer?
Make sure the water supply is connected and turned on. Plug the machine into a 230V outlet, press the ON button, and squeeze the trigger on the gun. The motor starts automatically when the trigger is pressed.
What is the maximum water temperature allowed?
Do not use hot water. The maximum inlet water temperature is 40°C (104°F). Using hotter water can damage the pump and void the warranty.
How do I attach the detergent suction hose?
Locate the detergent suction nozzle on the pump. Insert the suction hose into a container of detergent and attach the foam nozzle to the lance. The detergent is automatically mixed with water during operation.
What should I do if pressure fluctuates?
Check the water supply for proper flow, inspect the high-pressure hose for kinks, and clean the water inlet filter. Also verify that the nozzle is not clogged. Limescale in the nozzle can be cleaned with a needle.
Can I use the pressure washer without a water supply?
No, the machine is not designed for self-priming. Always connect it to a continuous water source. Running it dry can cause irreversible pump damage.
Is the machine suitable for cleaning cars?
Yes, with the adjustable nozzle set to low pressure and a safe distance (at least 30 cm). Avoid concentrated high-pressure spray on sensitive parts. Use the foam nozzle for shampooing.
How should I store the pressure washer in winter?
Drain all water from the pump, hoses, and lance. Store the machine indoors at temperatures above 0°C. Add antifreeze suitable for pressure washers if storage in a cold area is unavoidable.
What safety precautions should I take during operation?
Always point the spray away from people and animals. Wear protective eyewear and sturdy footwear. Do not touch the plug or socket with wet hands. Use only recommended accessories and never exceed the power rating.
