Congratulations! We’d like to say, “Thank You” for choosing the CONTRACTOR DIESEL. This instruction ma- nual is provided with your new High Pressure Washer to ensure that you obtain the best results, in the safest manner, with your new machine.
1.0 Safety Your CONTRACTOR DIESEL washer has been developed and manufactured in accordance with the latest working safety regulations. Caution! However, to prevent possible perso- nal accidents or damage to any other product, we advise you to read carefully through this section on safety precautions before you operate your washer for the first time.
Motor Protection Device The diesel engine is equipped with a protection device called ”Oil Alert”, which stops the engine if the oil level is insufficient. If this occurs, check the engine for leaks, and after making sure the machine is level, refill it to the proper level. The engine can then be restarted.
In order that you may make the most of your high pressure washer, ALTO has produced a very comprehensive accessory program, including a pneumatic tire kit especially for the CONTRACTOR DIESEL. Please feel free to contact your ALTO supplier for further information.
