2. SAFETY REGULATION
1. Read each contents of the manual before operation: abide this safety regulation to avoid any accident
or damage.
2. Check to make sure that the cleaner’s voltage conforms to that of the power source (220-240VAC),
and bearing current intensity of the transmission line is not less than 10A. According to this regulation,
the protective switch must be installed.
3. Cut off the power while the cleaner is not in operation.
4. Sure not to use the cleaner in the rain, and water is not allowed to spray on the machine to avoid
damage of the insulation.
5. Keep the power wires away from the heat source and sharp knife etc. so as to avoid damage.
6. Never insert or pull up the plug with wet hand, or trying to move the machine.
7. A damaged high-pressure hose must be replaced immediately. Only use hoses and connections

3. SCOPE OF APPLICATION
1. Use the appliance to clean various kinds of vehicles, such as cars
、
motors and bicycles etc.
2. Clean the outer wall of buildings

Working principle and structural characteristics
1. Working principle
The motor directly drives the gear shaft of the plunger pump. The sloping cam plate changes the turning
movement of the gear shaft into the reciprocation. When the plunger moves back, the water outlet valve
closes and forms a vacuum. And the water inlet valve opens, water goes into the cylinder through it;
when the plunger moves forward
，
the water inlet valve closes and the water pressure in the cylinder
increases. When the water outlet valve opens and the high-pressure water will be transported to the
hose.
