MAINTENANCE SCHEDULE
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 INSTALLATION
CHECKLIST in Installation Manual MP-04-01.
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.
Check that all Decals are in place, undamaged, and
legible (see DECALS pages).
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 anti-slip and safety striping is in place and
undamaged (see ANTI-SLIP & SAFETY STRIPING pages).
