I. INTRODUCTION
he RICON S-Series and K-Series Public Use wheelchair lifts provide wheelchair access to public use vehicles in-
cluding buses, school buses and large multi-purpose vehicles which are DOT compliant. The patented move-
ment provides a smooth, safe entry and exit and lifts up to 800 pounds (363) kilograms. It is to be operated by a
trained attendant. The lift contains a powerful electro-hydraulic pump that includes a built-in manual backup pump. If
the lift loses electrical power, it can be raised or lowered manually.
The S-Series has a solid, one-piece platform that is raised and folded into the vehicle when stowed. The platform on
the K-Series has a two-piece folding platform that splits horizontally to reduce overall lift height when stowed. This re-
sults in a less obstructed view, either into or out of the vehicle. The mechanical linkages provide smooth movement to
both non-skid platforms where the wheelchair and occupant are situated during the “Up” and “Down” lift motions.
This manual contains warranty information, installation instructions; maintenance and repair instructions; troubleshoot-
ing guide; parts and diagram lists that apply to Ricon S-Series and K-Series Public Use wheelchair lifts. It is important
to user safety that the lift operator be completely familiar with the operating instructions. Once the lift is installed, it is
very important that the lift be properly maintained by following the Ricon recommended cleaning, lubrication, and in-
spection instructions.
