Operation

Note

If the appliance is protected with antifreeze, this antifreeze must be purged from the wa- ter system (see chapter "Pumping anti- freeze out of the water system“).

Remove air from the high pressure system prior to operation!

ÎPress the release of the hand spray gun downwards.

ÎPull the lever on the handgun toward the back.

The motor goes to operating speed. The high pressure water stream is re- leased.

ÎTo switch off the high pressure spray, release the lever of the hand spray gun and let the release lock.

Note

Frequent switching on and off of the high pressure spray increase the wear and tear on the appliance and reduce its product life. Perform the cleaning process with as few interruptions as possible.

Shutting down

Note

Only use the Emerg Stop key in emergen- cies, not to switch off the appliance. A fre- quent use of the emergency stop key will increase wear and tear on the appliance.

ÎTo switch off the high pressure spray, release the lever of the hand spray gun and let the release lock.

ÎPress F3 key.

Depending on the load, the motor should somewhat longer to cool off.

ÎIf there is a risk of freezing tempera- tures during the operational break, flush the appliance with antifreeze (see Chapter "Antifreeze") or transport the appliance to an area protected from frost.

ÎTurn main key to "0" and remove it.

ÎClose and lock the operating panel door.

ÎOpen the hood and remove the key from the battery separating switch.

ÎUnscrew the high pressure hose, the water supply hose and the control line.

ÎProtect the hose connections and cou- plings from contamination with protec- tive caps.

Note

Do not store any objects (incl. hoses, ca- bles and spray units) inside the appliance. Use the storage compartment or storage box (option) to store these items.

Frost protection

Use commercially available glycol-based antifreeze for automobiles.

Observe the manufacturer's handling in- structions.

To protect from freeze damages, the appli- ance must be flushed with antifreeze.
