I. S-SERIES PRIVATE INTRODUCTION
he RICON S-Series Private Use wheelchair lift provides wheelchair access to vans and buses. The patented
movement provides smooth, safe entry and exit and lifts up to 800 pounds. It is to be operated by a trained at-
tendant. 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.
By using the lift control switches, the lift is unfolded out from the vehicle (deployed). The user boards the large non-skid
platform and the operator uses the control switches to gently lower the platform to the ground. After the user departs,
the platform is raised and folded into the vehicle (stowed). The lift is also available with a platform that splits and folds
when stowed, providing easy vehicle access through the lift.
This manual contains installation instructions; maintenance and repair instructions; troubleshooting guide; parts and di-
agram lists. 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 inspection instructions.

INSTALLATION
II. INSTALLATION
his chapter contains instructions for installing the Ricon S-Series Private Use wheelchair lift into most vans and
buses, although custom installations are also possible in other types of vehicles. Due to the wide range of appli-
cations for lift, specific information for every possible application is not available. The following general proce-
dures will apply to most installations. Contact Ricon Product Support for instruction concerning installations not cov-
ered. To install lift, refer to following sections and perform procedures carefully and in the order that they are presented.
Be certain that installation instructions are followed exactly and do not eliminate any steps or modify product.
NOTE: Please review carefully the installation instructions (32ii375e) that are supplied with this lift before beginning the
following procedures. Where these procedures conflict, the installation instructions take precedence.
A. GENERAL MECHANICAL INSTALLATION
1. LIFT LOCATION
The installation surface must be flat and level. It is recommended that lift be installed on a ½", minimum, high-
grade plywood sub-floor. However, this additional installation height may not be acceptable in cases where over-
head clearance is limited.
NOTE: Check for proper travel clearance through doorway.
a. With doors fully open, place/position lift in vehicle doorway as close as possible to door, with lift's baseplate
assembly parallel to side of vehicle.
b. Allow a distance of 3/4", if possible, between door and the part of lift closest to it. Adjust lift left and right-
side locations to accommodate subframe members.
c. Verify proper clearance of door frame, passenger seats, and outer edge of vehicle floor and possible inter-
ference with wires, fluid lines, subframe members, etc.
2. LIFT INSTALLATION GUIDELINES
The lift mounting is a very important step. Improper mounting or fastening of baseplate can adversely affect lift per-
formance. Although fastening details may vary from one vehicle to the next, these general principles apply:
♦Be certain that all mounting bolts are properly installed and tightened. Bolts used to fasten baseplate assembly
to vehicle floor must have a minimum strength rating of SAE Grade 5 and be torqued to 28 ft lbs, dry. Recog-
nize that the most important bolts are those along the rear of lift, since these bolts retain the majority of the
load.
♦Refer to Figures 2-1 and 2-5. Improper torquing sequence of baseplate bolts may result in a warped or bowed
baseplate, which can cause platform to move erratically.

e. Fasten Baseplate to Floor:
NOTE: If Ricon power door operators are used, install them first. They may influence location of lift.
Φ
Be certain baseplate is flush against vehicle floor. The baseplate may be slightly offset in door opening to
provide proper clearance for passenger seats.
Φ
Before drilling, verify that lift position does not interfere with closing of vehicle doors or operation of passen-
ger seats.
Φ
If this lift is being installed in a Dodge van with sliding doors, omit the bolts in baseplate holes 7 and 8.
f. Mark and Drill Holes:
CAUTION
Before drilling holes, verify that underlying wires and tubing will not be damaged.
1) Refer to Figure 2-5. Mark and drill five 25/64" baseplate mounting holes (1, 2, 3, 4, and 5) through ve-
hicle floor. (On Dodge and GM vans, you must drill through vehicle floor and subframe).
2) Place five 8" x 3/8" carriage bolts (use 4" x 3/8" bolts on Ford vans) into holes to secure position.
RSM0004300
FIGURE 2-5: VAN BASEPLATE HOLES
3) Refer to Figure 2-6 on the following page. Match and align top holes of stepwell brackets 6, 7, 8, and
9, with baseplate holes 6, 7, 8, and 9. Mark lower stepwell bracket holes 10, 11, 12, and 13 onto vehi-
cle step.
4) Remove five carriage bolts installed in step 2). Carefully push lift into vehicle interior.
5) Drill 1/4" dia holes through marked locations 10, 11, 12, and 13.

g. Fasten Bracket Assemblies and Lift:
1) Use 1-1/2" x 5/16" sheet metal screws with 5/16" lock washers to secure lower brackets to vehicle step
holes 10 through 13.
NOTE: If the screw in position 13 interferes with proper door operation, do not install.
2) Reposition lift and verify that surface beneath lift is free of obstacles.
3) Insert five 8" x 3/8" carriage bolts through mounting holes at rear of baseplate assembly, and insert four
1-1/2" x 3/8" carriage bolts through baseplate and bracket assemblies. Place 3/8" washers, lock wash-
ers, and nuts under bracket assemblies, and finger tighten nuts.
NOTE: On Dodge and GM vans, place five 4" x 4" plates, 3/8" washers, lock washers and hex nuts on 8" x 3/8"
carriage bolts under van and finger tighten. On Ford models, reinforce vehicle floor with clamping bars.
They are installed in positions 1, 2, 3, 4, and 5 and run across width of baseplate towards center of van.
4) Before tightening carriage bolts, verify that lift is level with vehicle floor. Adjust bracket assembly bolts if
necessary.
5) Tilting lift towards inside of van may hinder its initial unfolding. Install lift with its baseplate assembly as
level as possible. Tightening carriage bolts requires special care to keep baseplate assembly from
warping when secured to vehicle floor. If baseplate assembly warps, the vertical arms will not be paral-
lel. Make corrections by shimming at appropriate locations. To help prevent warping, tighten the eight
carriage bolts (six on Dodge van with sliding door) to 28 ft. lbs. in the appropriate sequence:
DODGE WITH SWING DOORS, ALL FORD AND GM VANS .......... 3, 1, 2, 4, 5, 6, 7, 8, 9
DODGE WITH SLIDING DOORS ...............................................................3, 1, 2, 4, 5, 6, 9
NOTE: Vertical arms must be parallel for proper operation. Adjust bolts as required. Best results are obtained
when lift is mounted on plywood. Shims, although best avoided, may be used if required.
6) Make certain that holes 14 and 15 on the front of each bracket assembly are drilled through, and 5/16"
bolts are inserted to lock position of bracket assemblies.

4. GROUND (COMMON) CONNECTIONS
a. 12VDC Systems
12VDC powered lifts are chassis grounded and do not require a separate ground cable connection to battery.
However, if the common side of the lift electrical system is connected to chassis with a cable, the cable must be
attached in a manner that provides a reliable electrical connection. If ground cable is attached to an existing
ground circuit, the circuit must be capable of conducting an additional 90 amps.
b. 24VDC Systems
1) Ricon recommends that a dedicated ground cable be used in 24VDC installations. A 4GA cable, or
heavier, must be used.
2) Refer to Figure 2-13. The ground cable is connected from the negative stud (-) on pump motor to the
negative battery terminal.
