I. INTRODUCTION

T his manual provides operating instructions for the Ricon PSL-10 Personal Step Elevator and

Wheelchair Lift as installed in transit vehicles.

The step-lift is semi-automatic and is operated by a trained attendant. It does not block the vehicle doorway when stowed, thus allowing normal boarding and deboarding at this point. Step-lift capacity is 600lbs (272kg).

It is important to user safety that these operating instructions be read and understood by the step-lift operator. It is also important that the Ricon recommendations for cleaning, inspecting and lubricating the step-lift be followed.

A. RICON PRODUCT SUPPORT

If there are questions about this manual, or you need copies, please contact the Ricon

Product Support Department at the following location:

The vehicle interlock conditions must be met and the vehicle doors must be open prior to deploying the step-lift. The platform is then manually unfolded to accommodate a wheelchair passenger, or left folded in its step configuration to accommodate a standing passenger. The step-lift lifts the passenger from the ground to the vehicle floor, or lowers the passenger from floor to ground. Lifting power is provided by an electro-hydraulic pump. After use the platform is refolded and then returned to its stowed position.

The step-lift has a manual backup pump that is used if normal power is lost.

2 - 4 32DSL101.B

C. CONTROLS

1. CONTROL PENDANT

Refer to Figure 2-5. The step-lift is raised and lowered with two rocker switches mounted in a small box, or pendant. The pendant is hard-wired to the step-lift with a cable. The pendant is usually stowed near the step-lift on a clip mounted to a vehicle interior wall. A lift function is initiated by pushing the end of the appropriate switch.

Push and hold the end labeled UP to raise the step platform; releasing the rocker switch will immediately halt movement. Push and hold the end labeled DOWN to lower the step platform; releasing the rocker switch will immediately halt movement.

Push and hold the end of the switch with the unlock symbol to release the stow lock (lock se- cures lift in stow position).

FIGURE 2-5: CONTROL PENDANT

NOTE: The step-lift must be raised about four inches above the stow position to allow release of the stow lock.

2. EMERGENCY OVERRIDE SWITCH

Refer to Figure 2-6. There are three interlock switches, two sets of contacts, and a connector in the platform. All of these switches and contacts must be working properly to enable operation of the platform. If one of these components fails, the platform can be re-enabled with the override switch. This red switch is mounted on the left side of the left-hand column. Press and hold the override switch while using the pendant.

3. MANUAL STOW-LOCK RELEASE CABLE

Refer to Figure 2-7. The stow lock secures the step/platform in the stow position. The cable is used to manually releases the step/platform and allow it to be lowered when normal power is not available to the step-lift. The cable is connected to a latch mechanism near the base of the right hand column. The step must be raised about four inches above the stow position to allow release of the latch.

FIGURE 2-6: OVERRIDE SWITCH

32DSL101.B

FIGURE 2-7: STOW-LOCK RELEASE

2 - 5

4. MIDDLE PLATFORM SECTION RELEASE HANDLE

Refer to Figure 2-8. This T-handle is located at the right side of the platform, and secures the front platform section to the middle section. It is accessible after the middle section is unfolded from its step configuration. The T-handle is spring loaded to the lock position and is disengaged by pulling to the left. When the front section is refolded back onto the middle section, the spring will force the shaft of the T-handle into a hole in the platform right side barrier.

FIGURE 2-8: MIDDLE SECTION RELEASE

T-HANDLE

5. FRONT PLATFORM SECTION HANDLE AND ROLLSTOP HANDLE

Refer to Figures 2-9. The front section handle is used to unfold the front platform section, or to grip the outer rollstop. When the platform is fully unfolded the handle is at the left end of the rollstop, as shown. When the rollstop is folded back against the front section the handle drops through a slot and protrudes out the back. This figure also shows the rollstop handle that is used to lift the rollstop out of its locking slots. The locking slots hold the rollstop in a vertical position.

FIGURE 2-9: FRONT SECTION HANDLE AND ROLLSTOP HANDLE

6. MANUAL BACK-UP PUMP

Refer to Figure 2-10. This pump is located on the right side of the right-hand column. When normal power is not available, the step-lift can be raised or lowered by using this manual back-up pump. The pump handle is stored near the pump. The handle is used to open and close the release valve or to pump the back-up pump.

FIGURE 2-10: MANUAL BACK-UP PUMP

III. OPERATING INSTRUCTIONS

Safe and efficient use of the RICON PSL-10 Step Elevator and Wheelchair Lift requires a thorough understanding of its operation. Please read and understand all operating instructions before using step-lift.

A. SAFETY PRECAUTIONS

The following safety precautions must be observed at all times:

•

Refer to Figure 3-1. It is dangerous to use the step-lift when the vehicle is on sloped ground or a steeply crowned road. Always attempt to park vehicle on a level, or near level, surface before using step-lift.

FIGURE 3-1: DO NOT USE STEP-LIFT WHEN VEHICLE IS

ON SLOPED GROUND.

•

Vehicle must have the parking brake applied, the transmission in neutral/park, and the doors open before using step-lift.

•

Before deploying or stowing step-lift, check area around step-lift for objects that could interfere with step-lift operation.

•

Do not change step-lift position unless operator can clearly see that it is safe to do so.

•

Inspect step-lift before loading passengers. Do not use step-lift if unsafe to do so, or if unusual noises or movements are present.

•

Keep others clear while operating step-lift.

•

Persons using mobility equipment (e.g., wheelchairs, scooters, etc.) must enter or exit vehicle slowly and carefully, and must always face OUTWARD.

•

Wheelchair and scooter brakes are less effective when the platform is wet or the mobility equipment wheels are wet. Be cautious in wet conditions.

•

The step-lift is designed for one user at a time. Do not overload step-lift. Be certain mobility aid equipment fits safely on platform before entering or exiting vehicle.

•

Never leave step-lift outside of vehicle; return step-lift to its stowed position after use.

•

Do not allow children or others to play on step-lift, as this may be dangerous.

•

Close supervision is necessary if step-lift is used near children.

•

Do not allow arms or legs in or near any moving parts of step-lift.

32DSL101.B

3 - 1

B. DAILY SAFETY CHECK

Inspect the step-lift each day, preferably just prior to use, and be certain that the following conditions are met:

•

All functions operate properly. DO NOT use if irregular noises or movements exist; contact an authorized Ricon service technician for repair.

•

No objects are present that may interfere with step-lift operation.

•

General appearance and lubrication are satisfactory.

•

All fasteners are tight.
