Barrier to prevent the wheelchair from rolling off of the platform.
MAINTENANCE SCHEDULE NOTE: The Lift controller counts the number of cycles & lifts over the lifetime of the Lift. One CYCLE is counted each time the Lift is unfolded from the stowed position to floor level, lowered to the ground, raised to floor level, and then stowed. One LIFT is counted each time the Lift is lowered from floor level to the ground, and raised back to floor level.
CHECKING HYDRAULIC FLUID LEVEL Keep dirt, water and other contaminants from entering the hydraulic system. Before opening the hydraulic fluid reservoir filler cap, drain plug and hydraulic lines, wipe off contaminants that can get in the openings. Also, protect the openings from accidental contamination. 1. Check the hydraulic fluid level in reservoir as follows. With Lift in STOWED, fluid level should be as shown in FIG. 11-1.
CHECKING HYDRAULIC FLUID LEVEL - Continued 3. Pull out filler cap (FIG. 12-1). Fill the reservoir with hydraulic fluid (TABLE 12-1) to level shown in FIG. 12-1. Reinstall filler cap (FIG. 12-1).

ADJUSTMENTS NOTE: Do this procedure if structure of the Lift is undamaged and: • The controller reads “MAT ERR” when the threshold plate is unoccupied and platform is below floor level. • The threshold warning beacons and threshold warning alarm are on when threshold is unoccupied and platform is below floor level. • The threshold warning beacons and threshold warning alarm will not turn on when threshold is occupied and platform is below floor level.
MAT SWITCH ADJUSTMENT - Continued 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 3. Set edge of the threshold plate to 5/8” height by turning the adjustment screw on the RH side of threshold plate (FIG. 18-1B). Turn adjustment screw counterclockwise (FIG. 18-2) to raise threshold plate or clockwise to lower. Repeat for LH side of threshold plate. Alternately measure height (see step 2).

Step on threshold plate. Warning alarm and beacons should activate. If the warning alarm and beacons do not activate, slightly turn adjustment screw (FIGS. 19-1B and 19-2) clockwise.
PLATFORM TILT ADJUSTMENT NOTE: The platform tilt adjustment is important for operation of the outboard rollstop and for keeping platform level when it reaches the ground. Vehicle floor height, Lift installation angle, and stiffness of the vehicle suspension may change the angle of platform on the ground. 11921 Slauson Ave. Santa Fe Springs, CA.
POWER SWITCH VERTICAL ARM GROUND LEVEL (1) 3. The measurement at the vertical arm (2) must be 1/2” -1” more than the measurement at the front of platform (1). For example: If you measure 4” at the front (1), then you should measure from 4-1/2” to 5” at the vertical arm (2). If there is not a 1/2” - 1” difference, go to step 4 to obtain the correct measurement. 4. Manually lower the Inboard Rollstop for access to the adjustment screws (FIG. 21-2).
CHANGING CONTROLLER TO SPANISH OR ENGLISH (IF REQUIRED) NOTE: The power switch on the Lift must be turned OFF before entering SETUP. UP FOLD 1.

STOW SWITCH ADJUSTMENT NOTE: Do this procedure if structure of the Lift is undamaged and: • Controller reads FOLD or UNFOLD when platform is stowed or has settled on the latches. • Vehicle will not move because interlock conditions are not being met. • The STOW switch is removed & replaced. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 The adjustment is done correctly if: • Platform stows tight.
To prevent possible injury, stay clear of the Lift when the controller repressurizes the hydraulic system. The system will repressurize every 5 minutes after the Lift is turned ON. If necessary, turn the Lift OFF and then ON again to continue the adjustment. RELEASE VALVE NOTE: When the power switch is turned on, you have 5 minutes to do the adjustment before the controller repressurizes hydraulic system and stows the Lift.

NOTE: Do this procedure if structure of the Lift is undamaged and: • Inboard rollstop does not land correctly on the threshold plate when unfolding platform or raising platform to floor level. • The angle position sensor (ILAPS) is replaced. • The controller is replaced. The adjustment is done correctly if: • Inboard rollstop rests on threshold plate and lines up approximately with edge of base plate. If the Lift requires frequent FLOOR POSITION ADJUSTMENT, replace the angle position sensor (ILAPS). 1.

TROUBLESHOOTING CONTROLLER DISPLAY READINGS The controller (FIG. 78-1) may display any of the following readings while the Lift is operating. Some of the readings indicate normal operation, but some indicate trouble with the Lift or vehicle. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 READINGS DISPLAYED HERE LIFT CONTROLLER DISPLAY FIG. 78-1 STOWED* (Stowed Star): Lift is operating normally and the controller (FIG.
Corrective action: 1. Make sure the stow switch is adjusted correctly. If required, do the STOW SWITCH ADJUSTMENT in this manual. With the platform resting on the latches, the stow switch must be closed. 2. If the adjustment does not solve the problem, check the wire that sends the Lift interlock signal to the vehicle interlock (see ELECTRICAL SYSTEM DIAGRAM). INBRD SW: The inboard rollstop is not completey closed and locked in position, or the inboard rollstop switch is always open. Corrective action: 1.
CONTROLLER DISPLAY READINGS - Continued MATT ERR: The Lift’s threshold plate sensed pressure while the platform was unfolded and more than 1” below the vehicle floor. There may be a load or occupant on it, or it may need to be adjusted. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 Corrective action: 1. Make sure the MAT switch is adjusted correctly. If required, do the MAT SWITCH ADJUSTMENT in this manual. 2. If adjustment does not solve the problem, do the following.
FOLD. (Fold dot): The platform does not pass the “Fold” switch, and the platform remains in position. The controller (FIG. 78-1) looks for a pressure reading that indicates an occupant is on the platform (50+ lbs). The platform must travel an adequate distance for the controller (measures hydraulic system pressure (PSI)) to determine if the platform can be folded. If the Lift stops folding in the middle of the platform occupant sensing area, the controller prevents the platform from folding.
CONTROLLER DISPLAY READINGS - Continued SEAT BLT: For units equipped with a seat belt, seat belt is unbuckled. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 Corrective action: 1. Buckle and unbuckle the seat belt. If the controller reads SEAT BLT when seat belt is unbuckled and clears when seat belt is buckled, the wiring connections and switch are good. 2. If the reading does not change, replace the seat belt.
LOW BAT: Battery voltage is below 12.2 volts. Controller allows the Lift to operate until battery voltage drops below 11.9 volts. Corrective action: 1. Start the vehicle to charge battery. 2. If that does not help, check if the battery is bad. 3. If the battery is OK, check to see if it is charging. 4. If battery is not charging, make sure the power cable and ground cable are in good condition, and the connections on both ends are clean and tight.
DIAGNOSTIC MODE CAUTION ! CAUTION Leaning on any part of the Lift while doing this procedure could result in personal injury and affect some of the diagnostic readings on the controller. 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 To display diagnostic readings on the controller: • If the platform is positioned above floor level (FIG. 84-1), press the UP button on the hand pendant (FIG. 84-2) rapidly 11 times. PLATFORM ABOVE FLOOR LEVEL (STOWED) FIG.

Electrical overload error codes are not displayed when the controller is in diagnostic mode. They are only displayed on the controller when an electrical overload error occurs while operating the Lift. Each function of the Lift is assigned a limit on how much electrical current it can draw. If the electrical current goes over the limit, the controller stops the Lift to prevent damage. The controller display will show which Lift function was operating at the time of the electrical overload.
DC RELAY READINGS 11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713 The DC Relay (FIG. 88-1) is a solid-state device for switching DC load current of up to 100 amps. Unlike a motor start switch (relay), the RED LED DC Relay uses only a few milliamps of current and has LED’s to indicate normal operation or fault conditions (FIG. 88-1 and TABLE 88-1). When the power switch on the Lift is turned on, it checks for power-reGREEN LED lated faults before applying power to the Lift.
