4. Do not allow any part of your body , or the Lift
occupant’s body, to be placed under , within, or
around any portion of the moving Lift or its mechanisms, or in a position that would trap them between the platform and the ground (or vehicle)
when Lift is operated.
5. Consider the safety and location of bystanders and
location of nearby objects when operating the Lift.
Stand to one side of plat form while operating the
Lift. Be certain that the area the Lift will move
through during operation is clear of all obstacles.
6. Fasten Occupant Restraint Belt Before Operating
Lift, but never tighten the belt. Leave a minimum of
3” - 4” slack in the belt. Lift will not operate correctly
and may become a hazard if belt is tight.
7. If Lift is not operated for several days or more it
may need to be repressurized. Use manual pump
to pressurize the system before operating the Lift
again. Low hydraulic pressure may cause Lift to
operate incorrectly and become a hazard.
8. Always operate the Lif t with the vehicle emergency
brake set and vehicle parked on Level ground.
Operating Lift without emergency brake set or
parked on an incline may create a hazard for
occupant and attendant.
9. Comply with all attached instruction decals and
warning decals.
10. Above all, USE GOOD COMMON SENSE when
operating this Lift.
1 1. Do not move vehicle when door is open.
ADDITIONAL SAFETY CONSIDERA TIONS
1. When using the Lift, wheelchair may face outboard
or inboard. If possible, position the wheelchair with
occupant facing outboard.
2. An ambulatory (st anding) occupant may face
outboard or inboard. If possible, position ambulatory occupant on the Lift, facing the direction of
travel (face vehicle when entering or face away
when exiting), and holding on the handrails.

DAILY PRE-OPERATION & OPERATION CHECKLIST
NOTE: PRE-OPERA TION and OPERATION CHECKS
should be performed by the Lift Operator.
PRE-OPERATION CHECKS
Park vehicle on level ground, shift vehicle
transmission to P ARK, and set vehicle emergency
brake before doing the following checks..
Visually check Lift for bent or broken parts, or for
hydraulic fluid around base. Have hydraulic fluid leaks,
and the fluid level in reservoir, checked by a qualified
technician.
Check for hydraulic fluid leaking from cylinders. Lift
may be operated if cylinders are “weeping” a light film
of hydraulic fluid. If hydraulic fluid drips from either
cylinder, have it checked by a qualified technician.
Check that all Decals are in place, undamaged, and
legible (see DECALS pages).
Check that all anti-slip and safety striping is in place
(see ANTI-SLIP & SAFETY STRIPING pages).
If the Lift is dirty, clean it.
Make sure the ON/OFF switch on the Pump Cover
is turned ON. If indicator on the switch is illuminated, Lift has power to operate.
P A TENTS PENDING
NOTE: If any of the PRE-OPERA TION CHECKS
have incorrect indications, do not operate
the Lift until repairs are performed by a
qualified technician.
OPERATION CHECKS
Operate the Lift through one full cycle to do
the following checks.
Use Lift operating instructions in this manual to
UNFOLD, LOWER, RAISE, and FOLD platform.
Make sure the Lift responds properly to hand
control switches.
Listen for unusual noises while the Lift operates.
Watch for uneven movement of the Lift arms,
platform, and inboard and outboard rollstop s.
NOTE: If any of the OPERA TION CHECKS have
incorrect indications, discontinue operating Lift until repairs are performed by a
qualified technician.

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.
NOTE: Only a qualified technician should do the sched-
uled maintenance on this page and confirm
compliance with Federal Motor Vehicle Safety
Standard 403. For the compliance checks, refer
to the COMPLETED LIFT INST ALLATION
CHECKLIST in Installation Manual MP-04-01.
EVERY 500 LIFTS
Visually check the Lift for bent, broken, or worn out parts,
and broken welds.
Check the electrical wiring for worn insulation, and the
terminals for corrosion and secure fit. Apply dielectric
grease to connections if needed.
Check for loose fasteners (nuts, bolts, screws & rivets).
Also, check cotter pins, clevis pins, retaining ring pins &
retaining rings for noticeable wear and damage.
Check that all Decals are in place, undamaged, and
legible (see DECALS pages).
Check that all anti-slip and safety striping is in place and
undamaged (see ANTI-SLIP & SAFETY STRIPING pages).
EVERY 2500 CYCLES
Replace both latch Solenoids P/N 266955-01
EVERY 3000 LIFTS
Check the Inboard Rollstop Actuator Assembly wiring
connections, routing, and condition from Actuator to
Controller. Repair if needed.
EVERY 5000 LIFTS
Check the large bearing on slider-end of Actuator. If
bearing looks worn at first inspection, remove and reinstall
bearing with the ends reversed. Replace bearing P/N
266545-03, if follow-on inspections reveal more wear.
Replace both Platform light bulbs P/N 906475-01.
EVERY 10000 LIFTS
Check both Hydraulic Cylinders for leaks. If a film of
hydraulic fluid is visible on cylinder seals Lift can still be
operated. However, if fluid is dripping from the cylinders,
replace them.
