General Safety Rules
IMPORTANT SAFETY INSTRUCTIONS
Read all safety warnings and all instructions. Failure to follow the warn-
ings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
When using this prod-
should be followed, including the follow­ing:
uct, basic precautions
Work area
Do not operate pressure washers in explo­sive atmospheres, such as in the presence of flammable liquids, gases or dust. Pres-
sure washer create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a pressure washer. Distractions
can cause you to lose control.
Store idle pressure washer out of reach of children and other untrained persons.
Tools are dangerous in the hands of untrained users.
Do not leave pressure washer running un­attended, turn power off. Do not leave pres-
sure washer until it comes to a complete stop.
Personal safety
Stay alert, watch what you are doing and use common sense when operating a pres­sure washer. Do not use a pressure washer while you are tired or under the influence of drugs, alcohol or medication. A moment
of inattention while operating pressure wash­ers may result in serious personal injury.
Always wear eye protection marked to comply with ANSI Z87.1 and use personal protective equipment. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appro­priate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the OFF position before con­necting to power source, picking up or car­rying the pressure washer. Carrying pres-
sure washers with your finger on the switch or energizing pressure washers that have the switch ON invites accidents.
Watch your balance and footing while us­ing your power washer. Surfaces become
slippery when wet and are extra slippery when using a detergent or cleaner.
Do not operate the equipment while bare­foot or when wearing sandals or similar lightweight footwear. Wear protective foot-
wear that will protect your feet and improve your footing on slippery surfaces.
Do not overreach. Keep proper footing and balance at all times. This enables better con-
trol of the pressure washer in unexpected situ­ations.

are hazardous to your health must not be sprayed. Your risk from these exposures var-
ies, depending on how often you do this type of work. To reduce your exposure to these substances: work in a well ventilated area, and work with approved safety equipment, such as masks that are specifically designed to filter out microscopic particles.
“Stay alert”. Do not allow familiarity gained from frequent use of your pressure washer to become commonplace. Always remem-
ber that a careless fraction of a second is suf­ficient to inflict severe injury.
Use only accessories that are recommend­ed by the manufacturer for your model. Ac-
cessories that may be suitable for one pres­sure washer, may become hazardous when used on another pressure washer.
Electrical safety
Pressure washer plugs must match the outlet. Never modify the plug in any way.
Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radia­tors, ranges and refrigerators. There is an
increased risk of electric shock if your body is earthed or grounded.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the pressure washer. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
This product is provided with a ground fault circuit interrupter (GFCI) built into the power cord plug. If replacement of the plug
or cord is needed, use only identical replace­ment parts.

pressure washer and have it serviced to correct malfunction if it fails the GFCI test.
Pressure washer use and care
Do not use the pressure washer if the switch does not turn it ON and OFF. Any
pressure washer that cannot be controlled with the switch may be dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing accessories, or storing pressure washers.
Such preventive safety measures reduce the risk of starting the pressure washer acciden­tally.
Store idle pressure washers out of the reach of children and do not allow persons unfamiliar with the pressure washer or these instructions to operate the pressure washer. Pressure washers are dangerous in
the hands of untrained users.
Follow the maintenance instructions spec­ified in the manual and maintain pressure washer. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the pres­sure washer’s operation. If damaged, have the pressure washer repaired before use.
Many accidents are caused by poorly main­tained pressure washers.
Use the pressure washer and accessories in accordance with these instructions, tak­ing into account the working conditions and the work to be performed. Use of the
pressure washer for operations different from those intended could result in a hazardous situation.
Hold the trigger handle and lance securely with both hands (one hand to pull the trig­ger and the other to stabilize the trigger handle/lance assembly). Expect the trigger handle to move when the trigger is pulled due to reaction forces. Failure to do so could
cause loss of control and injury to yourself and others.
Do not use acids, alkalis, solvents, flamma­ble material, bleaches, or industrial grade solutions in this product. These products
can cause physical injuries to the operator and irreversible damage to the machine. The sprayed vapor is highly flammable, explosive and toxic.

The detergent supply tube 14 is located on the back of the pressure washer. The tube is approximately 30cm/1ft long. When not in
use the tube is stowed inside the body of the washer so that just the filter tip is showing. When needed gently pull the filter tip and de­tergent supply tube out. Place the filter tip into your container of diluted detergent (Fig. 12).
Select the low pressure setting on the 3-in-1 nozzle 10 and begin cleaning.
When finished simply remove the detergent supply tube 14 from the container and wipe off any excess before gently feeding the tube back into the body of the pressure washer.
To flush out the pressure washer simply run with low pressure nozzle selection for one minute using clean water.
Use with Alternative
Water Sources
This pressure washer can be used with wa­ter tanks that have outlet connections. It’s IMPORTANT that the water is clean and the BOSCH inlet filter is clear and fitted to the ma­chine.
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.
