Protective suit against high-pressure water jets with arm and leg protectors.

High-pressure resistant to a maximum of 100 Mpa (flat jet nozzle).

The catching fixture connects the high-pressure hose to an attachment point on the device or high-pressure gun. It secures the high-pressure hose against whipping away if the hose connection is unintentionally released.

• Catching loop (textile): Order number 9.920-368.0

• Catching loop (steel rope): Order number 9.887-583.0

• Fastening rope (steel rope): Order number 6.025‌‌-311.0

Check the contents for completeness when unpacking. If any accessories are missing or in the event of any shipping damage, please notify your dealer.

• It is essential that you read the safety instructions 5.963-314.0 before initial startup.

• Observe the national regulations for liquid jet cleaners.

• Observe the national accident prevention regulations. Liquid jet cleaners must be tested regularly. The test result must be recorded in writing.

• Do not modify the device or accessories.

The device may not be connected to the public drinking water network.

The high-pressure jet must not be directed at persons, animals, live electrical equipment or at the device itself. Protect the device from frost.

Always wear hearing protection and safety goggles when working with the device.

Hot surface. Danger of burns. Do not touch. Only use the spray lance storage hooks for transport when the engine has cooled down.

Dangerous electrical voltage. Access only for qualified electricians.

Crushing hazard posed by the belt drive! Do not remove the protective cover. Do not reach underneath the cover.

Risk of damage to the high-pressure pump. Only regenerate the diesel particulate filter if the device is connected to a functioning water supply.

Observe the following warnings when handling the batteries:

	Observe notes in the instructions for the battery, on the battery and in these operating instructions.
	Wear eye protection.
	Keep acids and batteries away from children.
	Risk of explosion
	Fire, sparks, open flames and smoking are prohibited.
	Risk of acid burns
	First aid
	Warning
	Disposal
	Do not throw batteries in the bin.

The safety devices are set and sealed by the manufacturer. Adjustments are performed only by customer service.

The safety valve opens when the permissible operating pressure is exceeded and the water flows into the open.

The key-operated switch prevents the device from being started up unintentionally. Turn the key-operated switch to “0” when taking a break or finishing work and then remove the key.

The safety latch on the high-pressure gun prevents the high pressure water jet from being triggered unintentionally.

Only the Advanced version has this function.

When the high-pressure gun is closed, the overflow valve with pressure relief opens and all the water flows back to the suction side of the high-pressure pump. The pressure in the high-pressure hose drops. This reduces the actuating force of the high-pressure gun and extends the service life of the device.

The water shortage safeguard switches off the motor if the water supply is inadequate.

The water shortage safeguard indicator light lights up.

Only the Advanced version has this function.

The thermostat valve protects the high-pressure pump from overheating in circulation mode when the high-pressure gun is closes. The thermostat valve opens when the water temperature exceeds 80 °C and channels the hot water into the open.

Only EU version devices are equipped with the display.

   3. Engine oil dipstick
   4. Engine oil cap

4. Insert the dipstick into the engine as far as possible, then remove it again to check the oil level.

5. ATTENTION

   Risk of damage

   If contaminated or incorrect oil is used, it can damage the engine and reduce its service life.

   Only use the specified type of oil (see “Technical data”). Make sure the engine oil is not contaminated with any particles. Thoroughly clean the oil cap and dipstick and the surrounding areas. Do not mix different types of oil. Do not exceed the maximum oil level.

   If the oil level is near or below the lower limit marking on the dipstick:

   1. Unscrew the oil cap on the engine.

   2. Fill the recommended oil up to the upper limit marking. Do not overfill.

6. Reinsert the dipstick into the engine as far as possible.

7. Replace and tighten the oil cap.

1. Check the coolant level in the coolant expansion tank.

   When the engine is cold, the coolant level must be in line with, or slightly above, the lower marking.

   Note

   If the coolant is above the upper marking, it can escape from the tank due to thermal expansion that occurs when the engine is hot.

2. WARNING

   Risk of scalding

   Engine coolant can splash out and cause severe burns.

   Do not open the radiator cap. Always top up coolant via the expansion tank.

   ATTENTION

   Risk of damage

   Using the wrong coolant can result in the formation of rust and scale

   Only use approved coolant. Only use clean coolant. Clean the radiator cap and the adjoining surfaces before removing the radiator cap. Do not mix different coolants.

   If the coolant level is low, top up via the expansion tank.
