• Turn off the motor and press the trigger to pressure-purge the water.

Rinsing

• Remove the detergent nozzle and replace it with the high-pressure nozzle most suitable for the job.
  Follow the nozzle assembly and removal instructions and how to select the most adequate nozzle in page 9.

• Start rinsing from the upper side of the work area. Use side-to side passes, overlapping each pass up and down.

Moving the Pressure Washer

• Never use the handle to lift the Pressure Washer. Never set the unit in a position other than vertical and sitting on its wheels.

• Turn off the Pressure Washer.

• Tilt the unit towards you until is balanced on its wheels.
  Then, push it to the desired position. Do not tilt forward or sideways while moving it.

• DO NOT try to move the unit pulling from either of the hoses.

High Altitude Operation

• At high altitude the air fuel mix in the standard carburetor will be rich in fuel. Performance will be lower and fuel consumption will increase.

• Performance while in a high altitude can be increased if the carburetor is regulated adjusting the main knob. The equipment is set to operate at heights above 6000 feet above sea level. If the tool is not working efficiently call a Authorized Service Center to have them carry out modification in the carburetor.

• Even though the carburetor has an adequate injection the potency in the motor will decrease 3,5% approximately per each 1000 feet increment, after 6 890 feet above sea level.
  Decrease in potency will be higher if there are no modifications in the carburetor.

• If the equipment is operated in a height that is inadequate to the carburetor setting, low performance, over-heating and severe damage to the motor caused by the excessive air mix in the fuel may be obtained
