PREFACE
This is the User Manual for the PowerBoss®Atlas Rider Sweeper.
This manual covers all Standard Atlas machine variations beginning May 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 left side 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.
