INTRODUCTION T he Ricon S-Series and K-Series Public Use wheelchair lifts provide wheelchair access to public use vehicles including buses, school buses and large multi-purpose vehicles, and are DOT compliant. The platform on both S- and K-Series Public Use wheelchair lifts has a rated load capacity of 800 pounds, (364) kilograms. S-Series K-Series 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 splits horizontally to reduce overall lift height when stowed. This results 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. S- and K-Series Public Use wheelchair lifts contain an electro-hydraulic pump with a built-in manual backup pump. If the lift loses power, it can be raised or lowered manually. Trained personnel operate the lift by using a control pendant. The control pendant is used to unfold the platform out from the vehicle (deploy). The passenger boards the non-skid platform and an operator lowers the platform to the ground. After the passenger departs, the platform is stowed back into the vehicle. This manual contains warranty information, safety precautions, operating and maintenance instructions that apply to both Ricon S- 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 maintenance and inspection instructions provided in Chapter III. A.

OPERATING INSTRUCTIONS T his chapter contains safety precautions, daily safety check instructions, control and indicator descriptions, and operating instructions that apply to RICON S-Series and K-Series Public Use wheelchair lifts. This chapter must be thoroughly understood by the operator before using lift. A. SAFETY PRECAUTIONS The following safety precautions must be complied with at all times when operating lift: Refer to Figure 2-1. Deploying lift when vehicle is on sloped ground is hazardous. Operate lift with vehicle parked on level ground. FIGURE 2-1: SLOPED PARKING HAZARD Vehicle must be safely parked with parking brake ON before using lift. Inspect lift before use. Do not use lift if any unsafe condition exists, or unusual noises or movements are noticed, and contact an authorized Ricon service technician for repair. Read and comply with all warning labels and symbols affixed to wheelchair lift. Refer to Figure 2-2. Wheelchair occupant should face outward on platform when entering or exiting vehicle to minimize the possibility of the large rear wheels rolling up and over the front rollstop. FIGURE 2-2: EXITING BACKWARDS IS HAZARDOUS Do not rely on a threshold-warning device (audible, or other) to confirm that it is safe for a passenger to exit backwards. This device may be inoperative or unheard, and they might exit backwards when the platform is on the ground! When exiting vehicle, verify that platform is at same height as floor and front rollstop is up and locked. Do not place equipment or furniture inside vehicle that may prevent pivoting of your wheelchair. Being able to pivot assures that you can safely exit facing outward. Be certain wheelchair fits safely on platform; it must not extend beyond edges or interfere with operation of rollstop. 32DSKL01.B 2-1 The raised front rollstop prevents slow and unintentional rolling off of the platform. It is not intended to stop a fast-moving wheelchair, which might tip forward if the small front wheels collide with the rollstop. Do not operate with a load in excess of 800 lbs (364 kgs). Keep arms, legs, and clothing away from moving lift parts. The lift is intended for one wheelchair and its occupant or one standee. Do not overload lift. Refer to Figure 2-3. Do not stand in front of lift while deploying platform. FIGURE 2-3: STAND CLEAR OF LIFT Keep others clear while operating lift. Do not allow an untrained person to operate lift. Careful supervision is necessary if used near children. Do not allow anyone to stand on bridgeplate. A bent bridgeplate can interfere with the platform as it raises and lowers. Lock wheelchair brakes before moving platform (power chair users should turn off power and set brake). Use great care in wet conditions, because the wheelchair brakes are less effective if wheels or platform are wet. Never leave platform outside of vehicle. Return platform to stowed position after use. Do not load an oversize wheelchair into vehicle if it is too large to pivot freely inside vehicle. Read and understand these safety precautions. Review them periodically and ask other operators to read them as well. Contact an authorized Ricon service technician or call Ricon Product Support if there are questions. B. DAILY SAFETY CHECK Inspect lift before use and meet the following conditions: All functions operate properly. Do not use lift if unusual noises or movements exist, and contact an authorized Ricon service technician for repair. Vehicle interlock is operating properly. Objects that may interfere with operation are not present. General appearance and lubrication are satisfactory and fasteners are tight. 2-2 32DSKL01.B C. PLATFORM MOTIONS TABLE 2-1: PLATFORM MOTIONS MOVEMENT S-Series DESCRIPTION K-Series D E P L O Y Platform unfolds, or deploys, out of vehicle from stowed position to floor level position. If equipped with a power door operator, the doors automatically open before lift deploys. D O W N Platform lowers from vehicle floor level towards ground level. The front rollstop automatically lowers (opens) when platform reaches ground level. U P Platform rises from ground level towards vehicle floor level. The front rollstop automatically rises (closes) when platform leaves ground level. S T O W Platform folds, or stows, from vehicle floor level to the stowed position. If equipped with a power door operator, the doors automatically close after lift stows. END OF TABLE NOTE: The up and down functions do not operate if platform is in stowed position. STOWED POSITION NOTE: HANDRAILS AND PINCH POINT SHIELDS REMOVED FOR CLARITY. VEHICLE FLOOR LEVEL GROUND LEVEL FIGURE 2-4: PLATFORM POSITIONS 32DSKL01.B 2-3 D. CONTROLS AND INDICATORS WARNING THE LIFT CAN OPERATE ONLY WHEN THE VEHICLE MANUFACTURER INTERLOCK CIRCUITRY IS ACTIVATED. IF NECESSARY, REFER TO VEHICLE OPERATOR MANUAL FOR INTERLOCK INSTRUCTIONS. DO NOT ATTEMPT TO OPERATE LIFT WITH INTERLOCK BYPASSED. CONTROL PENDANT Refer to Figure 2-5. The lift is operated with four rocker switches and an ON-OFF switch located on the hand-held, hard-wired remote-control pendant. Turn on the POWER switch and then press an appropriate rocker switch to control each lift motion. The POWER switch enables the pendant by providing power to it and must be turned on before the lift can be operated. When turned on, the power switch will illuminate. Pressing the DEPLOY rocker switch unfolds the platform from the vehicle, and pressing the STOW rocker switch folds the platform back into the vehicle. Pressing the DOWN rocker switch lowers the platform towards the ground, and pressing the UP rocker switch raises the platform towards the floor. A rocker switch must be held depressed until the motion is completed. Movement of the platform can be halted at any time by releasing the rocker switch. The pendant is typically stowed on a wall-mounted clip inside the vehicle, near the lift. POWER ENABLE DEPLOY STOW DOWN UP FIGURE 2-5: CONTROL PENDANT 2-4 32DSKL01.B y CIRCUIT BREAKERS AND LED STATUS INDICATORS Pump Solenoid LED Status Indicators Refer to Figure 2-6. The pump has two solenoids that provide a margin of safety if one of them fails with its contacts closed. Green and red LED status indicators monitor the condition of the two solenoids, and are located between two 8A circuit breakers. The green LED is normally off when the pump is not operating and will illuminate when the pump operates. When the pump is not operating and the second solenoid has failed the red LED will illuminate. The green LED will illuminate if the first solenoid has failed. For more information on both indicator lights refer to Service manual 32DSKL02. LED STATUS INDICATORS 8 AMP HANDRAIL LIGHTS CIRCUIT BREAKER 8 AMP CONTROL SYSTEM CIRCUIT BREAKER 2ND SOLENOID 1ST SOLENOID FIGURE 2-6: PUMP SOLENOIDS LED STATUS INDICATORS y Main Circuit Breaker Refer to Figure 2-7. The main circuit breaker is located in the vehicle engine compartment and is used to interrupt electrical power to the lift electrical system when a major short circuit occurs. In such event, the circuit breaker reset tab will “flip-down”. If pressing reset tab back up (as shown by arrow) and releasing it does not reset power, do not press and hold tab. Contact a Ricon authorized service technician for repair. RESET TAB FIGURE 2-7: MAIN CIRCUIT BREAKER 32DSKL01.B 2-5 y Handrail Lights Circuit Breaker Refer to Figure 2-6. The circuit breaker for the handrail lights is located on the hydraulic pump assembly. In the event of a short circuit in the handrail lights, the circuit breaker button will “popout”. If pressing and releasing button does not reset power, DO NOT press and hold. Contact a Ricon authorized service technician for repair. y Control System Circuit Breaker Refer to Figure 2-6. The Control System Circuit Breaker is located on the hydraulic pump assembly. In the event of a short circuit in the control system, the circuit breaker button will “pop-out”. If pressing and releasing button does not reset power, DO NOT press and hold. Contact a Ricon authorized service technician for repair. BRIDGEPLATE LOAD SENSOR Refer to “Major Lift Components” section in Chapter I for the location of the sensor switch that detects the presence of a load on the bridgeplate. When the sensor detects that an object is present on the bridgeplate it inhibits lowering of the platform. This protects the passenger from possible injury when the bridgeplate rises, and also protects the bridgeplate from damage, which could later interfere with proper operation of the lift. THRESHOLD SAFETY WARNING SYSTEM Refer to Figure 2-8 for the location of threshold warning system components. The lift incorporates two light beams that detect when a passenger (or object, such as a wheelchair) is in the vicinity of the baseplate or bridgeplate (threshold area). The beams are enabled when the platform is one inch, or more, below the vehicle floor. If someone passes through either of the beams when the platform is one inch below the floor an audible alarm and flashing red light are actuated. This system provides a margin of safety for lift users by warning them if the platform is below floor level. The platform must be at floor level when boarding the platform prior to exiting the vehicle. FLASHING RED LIGHT AUDIBLE ALARM (INSIDE) LIGHT BEAMS APPROXIMATE THRESHOLD AREA FIGURE 2-8: THRESHOLD WARNING SYSTEM 2-6 32DSKL01.B MANUAL BACK-UP PUMP Refer to Figure 2-9. The manual backup pump is used to operate the lift if electrical power is not functioning. Controls for the pump are located inside housing of hydraulic unit and consist of a pump handle to raise platform, and a pump pressure release valve to lower it. Instructions for operating manual pump are provided in the “Manual Operation” section later in this chapter. PUMP HANDLE PUMP HANDLE SOCKET MANUAL BACKUP PUMP PUMP PRESSURE RELIEF VALVE FIGURE 2-9: MANUAL BACKUP PUMP & HANDLE LIFT CYCLE COUNTER Refer to Figure 2-10. The cycle counter is located inside the hydraulic pump housing and visible through a slot on the rear side. The counter advances each time the platform moves through a complete cycle, which consists of the platform moving from the vehicle floor to the ground and back to the floor. The number of cycles displayed is used to schedule maintenance operations. For maintenance schedule refer to Chapter III of this document. CYCLE COUNTER FIGURE 2-10: CYCLE COUNTER 32DSKL01.B 2-7 E.
