Safety Issues.
Safety precautions
• WARNING! High pressure jets can be dangerous. Never direct the water jet
at persons pets, live electrical equipment or the machine self.
• The operator and anyone in the immediate vicinity of the site of cleaning
should take action to protect themselves from being struck by debris dis-
lodged during operation. Wear goggles during operation.
• Never try to clean clothes or footwear on yourself or other persons.
• Do not let children or people who have not read the instruction manual
operate the machine.
• Never use the machine in an environment where there could be a danger of
explosion. If any doubt arises, please contact the local authorities.
• It is not allowed to clean asbestos- containing surfaces with high pressure.
• This high pressure washer must not be used

Dismounting / Mounting of Easy start valve.
Remove the easy seat with a small hook (fig.1) then remove the
o-ring underneath the seat ,with a small screwdriver .
Mounting : place the ball on the end of the spring (fig.2), be sure
the the ball are in the right position when mounting plug.

In this situation the position of the parts are following:
The none return valve( A) is closed by the spring (B) as there is no pressure
on either of the sides. The easy start ball valve (C) is pressed against the up-
per seat by the easy start spring (D) The s/s spring pressed the s/s piston,
and the Activation arm (E) is taken to the front position the micro switch (F) at
the “switch on” position, the motor (G) will start. The handle (H) is released,
No water flow from the nozzle.
Water flow: None

15
15 E
Operation guide.
1. The none return valve (A) is closed by the spring (B) as the pressure on the front
side is still not high enough to open it.
2. The easy start ball valve (C) moves a little from the upper seat as the easy start
spring (D) is pressed a little.
3. The s/s spring pressed the s/s piston, and the Activation arm (E) is taken to the
front position, the micro switch (F) at the “switch on” position, the motor (G) is running.
4. the handle (H) is released, and no water flow from the nozzle.
Water flows:
1. From the water inlet to the pump.
2. From the pump through the ball valve to the water inlet.

16
16 E
Operation guide.
During building-up of pressure, the position of the parts are following:
1. The none return valve (A) open a little because of the high pressure from pump.2.
The easy start ball valve (C) moves to the lower seat as the easy start spring (D)
impressed more.
3. The s/s spring pressed the s/s piston, and the Activation arm (E) is taken to the front
position, the micro switch (F) at the “switch on” position, the motor (G) is running. 4.
The handle (H) is released, and no water flow from the nozzle
Water flows:
1.From the water inlet to the pump
2. (Decreases during the process). From the pump through the ball valve to the water
inlet
3. From the pump through the none-return valve to the high pressure hose.

17
17 E
Operation guide.
1. The none return valve (A) is fully open because of full working pressure and flow.
2. The easy start ball valve (C) is pressed against the lower seat by the pressure
from the pump.
3. The s/s spring is pressed a little , but the Activation arm (E) is still on the front po-
sition, The micro switch (F) at “switch on” position. The motor (G) is running.
4. The handle (H) is activated, and water flow from the nozzle.
Water flows:
1. From the water inlet to the pump.
2. From the pump through the none-return valve to the high pressure hose.

18
18 E
Operation guide.
1. The none return valve (A) is closed by the pressure in the hose system.
2. The s/s spring is pressed at max position, the Activation arm (E) moves
back , presses the Micro switch (F) at “switch off” position (means that the
motor (G) is stopped).
3. The pressure in pump drop over a leak in the easy start valve, The easy
start spring presses the ball valve (C) up against the upper seat, pressure in
the cylinder head close to the inlet pressure.
4. the handle (H) is released, and no water flow from the nozzle
Water flows:
None
