1. Read the Maintenance Manual and understand it thoroughly before any maintenance of
this unit is done.
2. Read the YELLOW urgent warning decal on the side of the vehicle close to the unit before
operating.
3. If decals are dirty, clean them. If decals are defaced or missing, replace them. Free replace-
ments are available from the manufacturer. See information at the end of the Warnings
4. Be aware that the safety and location of other people or objects should be considered
before operation of this unit. Stand to one side of platform while operating this unit. Do not
stand in a position that would put you in the path of any moving vehicles around you.
5. Do not stand under, or have any foreign object under the Platform when lowering. Be sure
that the lowering of the Platform and/or Flipover will miss your feet!
6. Keep fingers, hands, arms, legs, and feet clear of moving parts when operating this unit.
7. If during your maintenance procedure, it becomes necessary to ride the platform, keep your
feet and any foreign objects clear of the rear edge of the platform. Otherwise your feet or
the foreign objects could become trapped between the edge of the platform and the vehicle
bed.
8. Inspect all Roll Pins monthly, to insure that they are not broken. Replace if broken.
9. Inspect all hydraulic hoses and fittings annually. Check for cracks and deterioration, and
replace if necessary.
10. Disconnect battery when replacing parts or servicing.
11. Do not allow children to ride, play with, or operate this unit.
12. In the event of an emergency while operating the unit, release the toggle switch and the unit
will stop immediately.
13. A properly installed Lift should operate smoothly and the only noise during the operation of
this unit should be from the Pump Unit during the raising of the Platform. Any scraping,
grating or audible indications of rough operation will need investigating. The cause will need
resolving before any further deterioration of performance occurs.
14. Use only Maxon Authorized Parts for replacement. Replacement parts should be ordered
from:

WARNING
READ CAREFULLY
• Improper operation of this Lift can result in serious personal injury.
Do not operate unless you have been properly instructed and have
read, and are familiar with the operating instructions. If you do not
have a copy of the instructions, please obtain them from your
employer, distributor, or lessor, before you attempt to operate Lift.
• Be certain that the vehicle is properly and securely braked before
using the Lift.
• Always inspect this Lift for maintenance or damage before using it. If
there are signs of improper maintenance, damage to vital parts, or
slippery Platform surface, do not use the Lift until these problems
have been corrected.
• Do not overload the Lift. The load limit is based on evenly distrib-
uted cargo over the entire Platform surface. If you are using a pallet
jack, be sure it can be maneuvered safely. Do not operate a forklift on
the Platform or travel with the platform in an open position at any time.
• Load should be placed in a stable position close to the edge of the
Platform nearest the truck. The heaviest portion of the load should
never be placed beyond the center of the Platform away from the
truck.
• Never allow yourself, a helper, or bystander to stand in a position
where a falling load could land on either of you. Also do not allow any
part of yours or your helper’s body to be placed under, within, or
around any portion of the moving liftgate, or it’s mechanisms, or in a
position that would trap them between the platform and the ground or
truck when the liftgate is operated.
• If a helper is riding the Platform with you, make sure you are both
doing so safely and that you are not in danger of coming in contact
with any moving or potentially moving obstacles. USE GOOD
COMMON SENSE. If load appears to be unsafe, do not lift or lower it.

PLATFORM ADJUSTMENT
Before adjusting platform, remove and inspect each of the hinge pins for
wear. (Ref. Hinge Pin Location Sheet) If any are worn, replace them. Also
check for structural damage. Either condition could make the platform appear
in need of adjustment. The Platform should reflect the YES illustrations below
with the Platform as much as 2-1/2” higher than the extension plate or floor
bed. There should be NO SAG in the Platform as pictured below.
Shackles also rest on the
ground. If Platform is straight, no
shimming is required. If Platform
sags, appropriate shims must be
added to both sides. Shims can
be placed in either or both posi-
tions.
