Caution

Do not completely deplete the fuel in the fuel tank, otherwise, the fuel system will have to be ventilated. Possibly suctioned dirt from the bottom of the tank can lead to malfunctions.

ÎCheck the fill level of the diesel fuel at the bar segment display for the fuel lev- el. If required, top off the diesel fuel. For temperatures below 0°, only use winter diesel.

Check the fill level in the water tank

ÎCheck the fill level of the water at the bar segment display for the water level in the tank. Top off the water tank if nec- essary. Connect the water supply hose to the water inlet.

ÎRemove the protective caps on the spray pipe.

ÎGrease the thread on the gun side with stainless steel screw grease (6.280- 180.0).

ÎScrew the pressure ring onto the spray pipe.

A

B

ÎThe sealing cone of the spray pipe must protrude about 1-1.5 thread lengths (B) from the pressure ring (A).

ÎRotate the pressure ring (A) by hand to adjust the distance (left thread).

ÎInsert the spray pipe all the way into the gun.

ÎSecure the spray pipe by tightening the pressure screw (torque approx. 100 Nm).

Connecting the nozzle

Do not perform this procedure until after the unit has been ventilated, see "Ventilating the high pressure system“.

ÎGrease the thread on the nozzle side with stainless steel screw grease (6.280-180.0).

ÎGrease the nozzle holder with stainless steel screw grease (6.280-180.0) and screw it onto the spray pipe (left thread).

ÎGrease the thread of the high pressure nozzle with stainless steel screw grease (6.280-180.0) and screw it onto the nozzle holder (hexagon socket).

Connect the high pressure hose to the gun and the appliance.

￿Danger

Risk of injury from leaks or water jets emerging from leaks.

Hoses, pipes and the spray unit must be in good condition and installed prop- erly.

Check the high pressure hose daily.

Only use original high pressure hoses that are approved for the respective pressure range and temperature.

Avoid contact with chemicals.

Do not use hoses with kinks.

Do not use the high pressure hose any- more if the thread is damaged or cor- roded.

Stop using the high pressure hose if the external wire layer is visible.

Do not route the high pressure hose across sharp edges.

Lay the high pressure hoses in such a way that no vehicle can drive over it.

Do not use high-pressure hoses that have been driven over, kinked, pressed or bent even if there is no externally vis- ible damage.

Completely lay out the high pressure hose, do not overlap.

High pressure hoses age with time. Re- place high pressure hoses every 6 years, even if they are in good condition.

High pressure hoses that have been stored for more than 2 years, may no longer be used.

Store the high pressure hose so that there is no mechanical strain. Store in a cool, dry and dustfree place.

Do not stretch the high pressure hose during storage, as the high pressure hose might change its length during op- eration.

Relieve tension from the high pressure hose after operation, purge excess wa- ter, coil it and store it properly.

ÎUnscrew the protective caps from the high pressure connection of the hand spray gun and pull off at the high pres- sure hose.

ÎClean the thread and grease it with stainless steel screw grease (6.280- 180.0).

ÎCheck the high pressure hose for flaw- less condition (no damage). Only use intact hoses.

ÎConnect the high pressure hose to the hand spray gun (procedure as de- scribed in Chapter "Connecting the spray pipe to the gun").

ÎRemove the protective cap from the high pressure outlet of the appliance.

EN - 6

ÎClean the thread and grease it with stainless steel screw grease (6.280- 180.0).

ÎConnect the high pressure hose to high pressure connection (procedure as de- scribed in Chapter "Connecting the spray pipe to the gun").

1Hose sock mounting

2Hose sock

ÎWhen using a hose sock to protect the high pressure hose from ripping off, hook the hose sock into the hose sock mount.

Connect the control line

ÎRoll the control line off the winch to hose length. Make sure that the control line is not underneath the high pressure hose, as the high pressure hose can rub against it and cause a line break.

ÎPull of the protective cap or antifreeze plug on the appliance connection side.

ÎConnect the short cable end of the winch with the socket.

ÎPlug the protective caps together to pre- vent soiling of the protective cap insides.

ÎConnect the control line on the gun side and plug the protective caps together.

Connect the water supply

According to the applicable regu- lations, the appliance must never be used on the drinking water net without a system separator. Use a

suitable system separator manufactured by Kärcher; or, as an alternative, a system separator as per EN 12729 Type BA.

Note

Water with drinking water quality with a pressure between 0.15 and 0.6 MPa (1.5 to 6 bar) is required to ensure a smooth oper- ation of the system.

ÎRemove the protective cap from the wa- ter supply inlet of the appliance.

ÎConnect the system separator to the water inlet (option).

AIf the system separator was installed, the water inlet is on the appliance
