NEPTUNE 5 SB FA

Do not touch, cover or place hose or cord over the chimney. Danger for persons, risk of overheating and fire.

Electrical equipment

CAUTION!

Never spray electrical equip- ment with water: risk of elect- trical shock and short-circuit.

The cleaner may only be con- nected to a correctly installed plug socket.

Switching on the cleaner may cause voltage fluctuations. Voltage fl uctuations should not occur if the impedance at the transfer point is less than 0.15Ω. If in doubt ask your local electric- ity supplier.

Maintenance and repair

CAUTION!

Always remove the plug from the power supply before clea- ning or carrying out mainte- nance work on the cleaner.

Carry out only the maintenance operations described in the oper- ating instructions. Use only origi- nal Nilfisk-ALTO spare parts.

Do not make any technical modi- fications to the high-pressure

cleaner.

Ensure that the machine is regu- larly serviced by authorized Nil-

fisk-ALTO dealers in accordance with the maintenace plan. Failure to do so will void the warranty.

CAUTION!

High-pressure hoses, fittings and couplings are important for the safety of the cleaner. Use only high-pressure parts approved by the manufac- turer!

The power cord must not differ from the version specifi ed by the manufacturer and may only be changed by an electrician.

Please contact your local author- ized Nilfisk-ALTO equipment dis- tributor for all other maintenance or repair needs!

Testing

The cleaner conforms to the Ger- man „Guidelines for Liquid Spray Jet Devices“. The high-pressure cleaner must be subjected to a safety examination in accord- ance with the „Accident Preven- tion Regulations for Working with Liquid Spray Jet Devices“ as required, but at least every 12 months, by an authorised inspector.

After all repairs or modifica- tions to electrical equipment,

the protective conductor resist- ance, the insulation resistance and the leakage current must be measured. Furthermore, a visual inspection of the mains power cord, a voltage and current measurement and a function test must be carried out. Our after- sales service technicians are at your disposal as authorised inspectors.

The complete „Accident Preven- tion Regulations for Working with Liquid Spray Jet Devices“ are available from the Carl Hey- manns Verlag KG, Luxemburger Strasse 449, 50939 Cologne or from the appropriate associa- tion of employers’ liability insur- ances.

The pressure-bearing parts of this high-pressure cleaner have been manufactured in accord- ance with § 9 of the German Pressure Vessels Ordinance and successfully subjected to a pressure test.

Bypass valve

The pressure is reduced by means of a "bypass valve" which returns water to the inlet side of the pump at a minimum pressure. The point at which this occurs is set and sealed at the factory and must not be adjusted.

2 Description

2.1 Purpose	This high-pressure cleaner has
	been designed for professional
	use. It can be used for cleaning
	agricultural and construction
	equipment, stables, vehicles,
	rusty surfaces, etc.
	The cleaner has not been ap-
	proved for cleaning surfaces
	which comes into contact with
	food.

Chapter 5 describes the use of the high-pressure cleaner for various cleaning jobs.

Always use the cleaner as de- scribed in these operating in- structions. Any other use may damage the cleaner or the sur- face to be cleaned or may result in severe injury to persons.
