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. Read the LIFTS and CYCLES counts from the Lift
Controller display window periodically so you know when to do the maintenance
checks listed below.
EVERY 500 LIFTS
11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713

TROUBLESHOOTING
CONTROLLER DISPLAY READINGS
The Controller (FIG. 72-1) 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.

READINGS
DISPLAYED HERE
LIFT CONTROLLER DISPLAY
FIG. 72-1
STOWED* (Stowed Star):
Lift is operating normally and the Controller (FIG. 72-1) is receiving the interlock signal
from the vehicle. The platform has folded, passed the stow switch, and is stowed. The
hydraulic system pressure is above 900 PSI and the Lift interlock signal is being sent to
the vehicle.
STOWED.* (Stowed Dot Star): Lift is operating normally and the Controller (FIG. 72-1)
is receiving the interlock signal from the vehicle. The platform has folded, passed the stow
switch,and is stowed. The hydraulic system pressure is below 900 PSI. When the Controller recharges hydraulic system pressure every 5 minutes, the dot (.) will go away and
Controller (FIG. 72-1) will read STOWED*.
STOWED (Stowed): Lift is operating normally and the Controller (FIG. 72-1) is receiving
the interlock signal from the vehicle, but the Lift interlock signal is not reaching the vehicle
interlock. The platform has folded, passed the stow switch, and is stowed. The hydraulic
system pressure is above 900 PSI. If vehicle interlock uses the absence of the Lift interlock signal to prevent vehicle from being moved when lift is not properly stowed, then
vehicle will not be allowed to move until it receives interlock signal from the Lift.
Corrective Actions:
1. Make sure the Stow switch is adjusted correctly.
If required, do the STOW SWITCH ADJUSTMENT in this manual. When the platform is resting on the latches, the STOW switch must be closed.
2. If the adjustment does not solve the problem, then check the wire that sends Lift
interlock signal to the vehicle interlock (see ELECTRICAL SYSTEM DIAGRAM).
PATENTS PENDING
72
Corrective Actions:
1. Make sure the Stow switch is adjusted correctly.
If required, do the STOW SWITCH ADJUSTMENT in this manual. When the platform is resting on the latches, the STOW switch must be closed.
2. If the adjustment does not solve the problem, then 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 Actions:
1. Close the Inboard Rollstop. Make sure closing mechanism is working correctly.
2. If the problem remains, go to the diagnostic mode on the Controller and check the
“Inboard Rollstop” switch code (see DIAGNOSTICS). The 2nd digit in the second
set of binary codes (00001111) indicates the “Inboard Rollstop” switch. With the
Inboard Rollstop open, push the switch actuator mechanism. If the digit changes
from 0 to 1 or from 1 to 0, then the wiring connections and switch are good.
3. If the Controller (FIG. 72-1) still reads INBRD SW, replace the Controller.
OUTBD SW:
The Outboard Rollstop is not completey closed and locked in position, or the Outboard
Rollstop Switch is not functioning correctly.
Corrective Actions:
1. Go to diagnostic mode on the Controller and check the “Outboard Rollstop”
switch code (see DIAGNOSTICS). The 1st digit in the second set of binary codes
(00001111) indicates the “Outboard Rollstop” switch. With the Outboard Rollstop
open, the digit should be “0”. If closed, the digit should be “1”.
If the digit does not change when Outboard Rollstop opens and closes:
• Check and repair switch wiring
• Replace switch or magnet
2. If the Controller (FIG. 72-1) still reads OUTBD SW, replace the Controller.

STOWED. (Stowed dot):
Lift is operating normally and the Controller (FIG. 72-1) is receiving the vehicle’s interlock
signal, but the Lift interlock signal is not reaching the vehicle interlock. The platform has
folded, passed the stow switch, and is stowed. The hydraulic system pressure is below
900 PSI. When the Controller recharges hydraulic system pressure every 5 minutes, the
“.” (dot) will go away and Controller (FIG. 72-1) will read STOWED. If the vehicle interlock
uses the absence of the Lift interlock signal as a condition to prevent vehicle from being
moved (Lift is not stowed correctly), then vehicle will not be allowed to move until it receives the Lift interlock signal.
CONTROLLER DISPLAY READINGS - Continued
MATT ERR:
The lift’s Threshhold Plate has pressure on it. 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 Actions:
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, go to the diagnostic mode on the Controller and check the “Mat” switch code (see DIAGNOSTICS). The 6th digit in the first
set of binary codes (11110001) indicates the “Mat” switch. Push the actuator lever on
each of the 2 MAT switches (only one at a time). If the digit changes from 0 to 1 or
from 1 to 0, then the wiring connections and switch are good.
3. If the Controller (FIG. 72-1) still reads MAT SW, replace the Controller.
LOCK ERR:
Lift is not stowed, and the interlock signal from the vehicle is not reaching the Controller.
For the vehicle interlock to send a signal to the Lift, the vehicle transmission must be in
park or neutral, emergency or service brakes must be set, and Lift switch or other controls
(as equipped) must be set correctly. Lift can be operated until stowed. Then the Lift cannot
be operated until it receives the interlock signal from the vehicle.
Corrective Actions:
1. Check all the conditions, controls, and settings on the vehicle interlock and then
check the interlock connections to the Lift (see ELECTRICAL SYSTEM DIAGRAM).
2. Disconnect the vehicle interlock wire (white with red stripe) from the Lift (see ELECTRICAL SYSTEM DIAGRAM). (The vehicle interlock wire is on the same side as
the pump.) Then connect the wire to ground. If the LOCK ERR reading is gone from
the Controller (FIG. 72-1), the Lift interlock is operating correctly, get the vehicle
interlock repaired.
LOCKED:
This is a normal reading on the Controller (FIG. 72-1) if the Lift is stowed and vehicle is
being driven. It indicates the Lift cannot be operated because it is not getting the interlock
signal from the vehicle. The vehicle normally sends the interlock signal to the Lift when vehicle transmission is in park or neutral, emergency or service brakes are set, and Lift switch
or other controls (as equipped) are set correctly. For the Lift to operate, the Controller must
display a STOWED (see STOWED*, STOWED.*, and STOWED).
PATENTS PENDING
74
FOLD SW:
The switch state (open or closed) does not match the position of the platform. This reading
indicates the “Fold” switch is broken or the wiring is disconnected or damaged.
FOLD. (Fold dot):
The platform did not pass the “Fold” switch, so the platform is still positioned where the
Controller (FIG. 72-1) looks for a pressure reading that indicates an occupant on the platform (50+ lbs). The Controller needs the platform to travel a certain distance to measure
the hydraulic system pressure (PSI) so Controller can determine if it is okay to fold platform.
If the Lift stopped folding in the middle of the platform occupant sensing area, the Controller will not allow the platform to continue folding. To continue operation, platform must be
unfolded completely.
Corrective action:
Completely unfold the platform to floor level. Then the Controller will allow the platform to
be folded and stowed.
UNFOLD. (Unfold dot):
The platform did not pass the “Fold” switch, so the platform is still positioned where the
Controller (FIG. 72-1) looks for a pressure reading that indicates an occupant on the platform (50+ lbs). The Controller will not allow the platform to be folded, so it can only be
unfolded at this point. To continue operating the Lift, platform must be unfolded completely.
Corrective action:
Completely unfold the platform to floor level. Then the Controller will allow the platform to
be folded and stowed.
UNFOLD. OCCUPIED (Unfold dot Occupied):
Platform was occupied (50+ lbs. on platform) when trying to fold the platform.
Corrective action:
1. Remove occupant (or load) from platform.
2. If there is no occupant or load, go to diagnostic mode on the Controller (see DIAGNOSTICS) and read the hydraulic system pressure. Pressure should read between
170PSI to 230PSI. If it is not in the range, change the Pressure Transducer.
3. If it is within range, the platform occupied pressure setting must be changed in the
Controller.

STOW SW:
The “Stow” switch is normally closed when the Lift is not stowed. This reading indicates the
Stow switch is broken or the wiring is disconnected or damaged.
CONTROLLER DISPLAY READINGS - Continued
GRND SW:
This is the Controller reading (FIG. 72-1) if the “Ground” switch is not open when the
platform is more than 3” off the ground. (Ground switch senses when platform is 3” off the
ground.)
11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713
Corrective action:
1. Go to diagnostic mode on the Controller (see DIAGNOSTICS) and check the
“Ground” switch code. The 5th digit in the first set of binary codes (11110000)
indicates the “Ground” switch. With the Outboard Rollstop closed, the digit should
be “0”. If open, the digit should be “1”. If the digit does not change when Outboard
Rollstop opens and closes:
• Check and repair switch wiring
• Replace switch or magnet
2. If the Controller (FIG. 72-1) still reads GRND SW, change the Controller.
LOWERING SW:
The state (open or closed) of the “Lowering” switch does not match the position of the
platform.
Corrective action:
1. Check the mechanism that activates switch. Then check if the switch is bad.
2. Go to diagnostic mode on the Controller (see DIAGNOSTICS) and check the “Lowering” switch code. It is the 3rd digit in the second set of binary codes (00001111).
Push the actuator lever on the “Lowering” switch. If the number changes from 0 to
1 or from 1 to 0, then the wiring connections and switch are okay.
3. If the Controller (FIG. 72-1) still reads GRND SW, change the Controller.
4. If the digit does not change, replace the “Lowering” switch
SEAT BLT:
Seat belt is not buckled (only on units equipped with a seat belt).
Corrective action:
1. If the belt is engaged, go to diagnostic mode on the Controller (see DIAGNOSTICS) and check the “Seat Belt” switch code. It is the 8th digit in the first set of
binary codes (11110000). Buckle and unbuckle the Seat Belt. If the digit changes
from 0 to 1 or from 1 to 0, then the wiring connections and switch are okay.
2. If the Controller (FIG. 72-1) still reads SEAT BLT, change the Controller.
3. If the digit does not change, replace the seat belt.

Corrective action:
1. Remove occupant or load from the platform.
2. If there is no occupant or load, go to diagnostic mode on the Controller (see DIAGNOSTICS) and check the hydraulic system pressure reading (PSI). It should
be between 170PSI to 230PSI. If reading is not in the range, change the Pressure
Transducer.
3. If the Controller (FIG. 72-1) still reads “OCCUPIED”, the platform occupied pressure
setting must be changed in the Controller or the Controller must be changed.
PSI SEN:
The Pressure Transducer is reading outside of the acceptable range of hydraulic system
pressure (PSI) for the function that Lift is performing.
Corrective action:
1. Check for disconnected or damaged Pressure Transducer wiring.
2. If wiring is okay, replace Pressure Transducer
LOW BAT:
Battery is below 12.2 volts. Controller allows the Lift to operate until battery voltage goes
below 12.0 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.
CHRG BAT:
This reading appears when the platform is being raised or lowered and the battery is below
12.0 volts. The Controller will only allow the platform to be raised, folded, and stowed until
battery is re-charged.
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 okay, 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.

Overload Error code readings are not displayed
when the Controller is in diagnostic mode. They
are only displayed on the Controller when an
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. Then the
Controller reading will show which Lift function
was operating at the time of the overload. The
Controller reading will flash between ERROR:
OVERLOAD! (FIG. 84-1) and an 11-digit code
(i.e. 00100000000) (see FIG. 84-2 & TABLE
84-1). A “1” in the output code means that a
specific function was on when the overload occurred, and “0” means that a specific function
was off when the overload occurred.
