Maintenance and Troubleshooting

18 Owner’s Manual for Power Washer

• Cover unit with a suitable protective,

moisture resistant cover.

• Store unit in a clean and dry area.

• Always store power washers and fuel away

from heat and ignition sources.

Prepare Fuel System for Storage

Fuel stored over 30 days can go bad and

damage fuel system components. Keep fuel

fresh, use fuel stabilizer.

If fuel stabilizer is added to fuel system,

prepare and run engine according to Power

Washer Start-Up Run engine for 2 minutes to

circulate stabilizer throughout fuel system.

Adequately prepared fuel can be stored up to

24 months.

NOTE: If fuel has not been treated with fuel

stabilizer, it must be drained into an approved

container. Run engine until it stops from lack

of fuel. Use of fuel stabilizer in fuel storage

container is recommended to keep fuel fresh.
