are hazardous to your health must not be sprayed. Your risk from these exposures varies, 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 remember 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. Accessories 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.

•GFCI does not protect against electrical shock due to contact with both circuit conductors or a fault in any wiring supplying this device.

•Test GFCI before each use. Do not use 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.
