  • If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
  • If the plug is damaged, pay attention to the following:
  • Plugs and sockets situated near the work site or outdoors should be to class IP 55 of BS 5490 to provide adequate protection against ingress of water, etc. and cable entries require effective sealing. Rubber shrouds should be provided over cable glands. Drip-proof (class IP X2  of BS 5490) plugs and sockets to BS 4343 are suitable for use indoors where the plug is away from the water spray area where the appliance is in use.
  • Never touch the mains plug with wet hands.
  • Do not pull plug while operating the device.
  • Do not run over, crush or pull the power supply cord or extension cord, otherwise it may be damaged. Protect the cable from heat, oil and sharp edges.
  • Do not use the unit, if the power supply cord or important parts, e. g. high-pressure hose, power gun or safety devices are damaged.
  • Warning: Inadequate extension cables can be dangerous.
  • If an extension cord is used, the plug and socket must be of watertight construction. The extension cord must have a cross section in accordance with the operating instructions and be protected against splashed water. The connection must not be in water.
  • When replacing plugs on the power supply cable or extension lead the spray water guard and mechanical stability must remain intact.

Water connection

  • Comply with the regulations of your water supply company.
  • All connecting hoses must have properly sealed joints.
  • Make sure that the supply hose is at least 12.7 mm (1/2″) in diameter and is reinforced.
  • The appliance should never be used on the drinking water supply without a back flow valve. Water which has passed the back flow valve is regarded as undrinkable.
  • The high-pressure hose must not be damaged (danger of bursting). A damaged high-pressure hose must be replaced immediately. Only use hoses and connections recommended by the manufacturer.
  • High-pressure hoses, fittings and couplings are important for the safety of the appliance. Use only hoses, fittings and couplings recommended by the manufacturer.

The operating voltage is 230 V AC, 50 Hz (for non-EU countries 220 V, 240 V as applicable). Contact your Bosch Service Centre for details. If in doubt contact a qualified electrician or the nearest Bosch Service Centre.
If you want to use an extension cable when operating your high pressure washer, only the following cable dimensions should be used:

  • 2.5 mm²
  • max length 25 m
    Note: If an extension cable is used it must be earthed and connected through the plug to the earth cable of your supply network in accordance with prescribed safety regulations. If in doubt contact a qualified electrician or the nearest Bosch Service Centre.

Warning: Inadequate extension cables can be dangerous. Extension cable, plug and socket must be of watertight construction and intended for outdoor use.

The connections (plugs and sockets) should be kept dry and off the ground. For increased electrical safety use a Residual Current Device (RCD) with a tripping current of not more than 30 mA. Always check your RCD every time you use it. If the supply cord is damaged, it must be replaced by a Bosch Service Centre.
For products not sold in GB:
Warning: For your safety, it is required that the plug attached to the product is connected with the extension cord. The coupling of the extension cord must be protected against splash water, be made of rubber or coated with rubber. The extension cord must be used with a cable strain relief.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket elsewhere.

  • Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.


  • To prevent damage to the appliance, do not allow it to operate dry.

Working Advice


  • Never use a roto nozzle or pencil jet to clean motor vehicles.
  • Ensure that the pressure washer is on level ground.
  • Do not overreach with the high pressure hose or move the pressure washer by pulling the hose, this could cause the machine to become unstable and fall over.
  • Do not kink or drive a motor vehicle over the high pressure hose. Do not expose the high pressure hose to sharp edges or corners.

Working advice for cleaning with detergents

  • Only use cleaning agents suitable specifically for high pressure washers.
  • We recommend that you use detergent sparingly for the sake of the environment. Observe the recommended dilution on the detergent label.

Recommended cleaning method

  • Step 1: Attach the fan nozzle and remove the heavy dirt.
  • Step 2: Attach the foam bottle and spray on the detergent sparingly.
  • Step 3: Rinse off the loosened dirt and detergent with the fan nozzle.
    Note: When cleaning a vertical surface spray off dirt/detergent from the bottom and work in an upwards direction. Rinse from the top and work downwards.

Use with alternative water sources
This high-pressure washer will self prime and can draw water from water tanks and natural water sources. It is IMPORTANT that the water is clean and the BOSCH inlet filter is clear and fitted to the machine.

Open tanks/containers and natural water sources
Use the Self Priming accessory kit comprising:

  • Inlet strainer with non return valve
  • 3 m reinforced supply hose
  • Universal coupling to the pressure washer

This enables the pressure washer to draw water up to 0.5 m above the water level in the source. This may take up to 15 seconds.
Submerge the 3 m hose in water to displace the air. Connect the 3 m supply hose to the pressure washer ensuring that the inlet strainer remains submerged in the water source. Run the pressure washer with the lance disconnected until a steady flow of water appears from the high pressure hose. Stop if this has not been achieved within 25  seconds and check all the connections. Switch off and connect the lance and nozzle to operate. It is important to ensure that all hose and coupling connections are of good quality, air tight and that all washers are in good condition and correctly seated in place. Failure to do so may affect the self priming performance.

Water Tanks with outlet connections
When connecting the pressure washer to a water tank with a suitable tap outlet, first connect the supply hose (not provided) to the tank outlet, open the tap to allow the water to displace all the air in the hose and then connect to the pressure washer.
