This is the User Manual for the PowerBoss® Nautilus Rider Scrubber/Sweeper. This manual covers all Standard Nautilus machine variations beginning July 2015. We believe this machine will provide excellent service for many years. However, the best results will be obtained if:

• The machine is operated with reasonable care.

• The machine is maintained regularly per the maintenance schedule provided in this User Manual.

• The machine is maintained with PowerBoss® supplied or equivalent parts.

All right side and left side references to the machine (except for engine) are determined by facing the direction of forward travel. The front of the engine or engine fan faces the front of the machine. Some hardware considered to be common or locally available has been omitted from the parts section to make this manual clear. Be sure to use equivalent hardware when replacement becomes necessary.

The Model and Serial Number of your machine is shown on the I.D. name plate. This information is needed when contacting Technical Support or when ordering parts. The I.D. plate is mounted on the left side wall of the operator seating area.

SAFETY INFORMATION

BASIC POWERBOSS® SAFETY

PowerBoss® scrubbers should never be operated unless:

1. The operator is trained and authorized to operate the equipment and,

2. The equipment is functioning correctly. Malfunctioning equipment should be removed from service.

DANGER

Keep cigarettes, matches and all other ame sources

away from the machine. Gasoline, LP Gas, and diesel

fuels are highly ammable. Lead acid batteries

are equally dangerous due to the highly explosive hydrogen gas they emit.

WARNING
