WARNINGS
!
WARNING
11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713
• Do not stand, or allow obstructions, under the platform when lowering the Liftgate. Be sure your
feet are clear of the Liftgate.
• Keep fingers, hands, arms, legs, and feet clear of moving Liftgate parts (and platform
edges) when operating the Liftgate.
• Correctly stow platform when not in use. Extended platforms could create a hazard for
people and vehicles passing by.
• Disconnect Liftgate power cable from battery before repairing or servicing Liftgate.
• If it is necessary to stand on the platform while maintaining the Liftgate, keep your feet and any
objects clear of the inboard edge of the platform. Your feet or objects on the platform can become
trapped between the platform and the Liftgate extension plate.
• Recommended practices for welding on steel parts are contained in the current AWS (American
Welding Society) D1.1 Structural Welding Code - Steel. Damage to Liftgate and/or vehicle, and
personal injury could result from welds that are done incorrectly.
• Recommended practices for welding on aluminum parts are contained in the current AWS
(American Welding Society) D1.2 Structural Welding Code - Aluminum. Damage to Liftgate
and/or vehicle, and personal injury could result from welds that are done incorrectly.
• Recommended practices for welding galvanized steel are contained in the current AWS (American Welding Society) D19.0 Welding Zinc-Coated Steel. Damage to Liftgate and/or vehicle, and
personal injury can result from welds that are done incorrectly.

SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
• Before operating the Liftgate, read and understand the operating instructions in Operation
Manual.
• Comply with all WARNING and instruction decals attached to the Liftgate.
• Keep decals clean and legible. If decals are illegible or missing, replace them. Free replacement
decals are available from Maxon Customer Service.
• Consider the safety and location of bystanders and location of nearby objects when operating the
Liftgate. Stand to one side of the platform while operating the Liftgate.
• Do not allow untrained persons to operate the Liftgate.
• Wear appropriate safety equipment such as protective eyeglasses, faceshield and clothing while
performing maintenance on the Liftgate and handling the battery. Debris from drilling and contact
with battery acid may injure unprotected eyes and skin.
• Be careful working by an automotive type battery. Make sure the work area is well ventilated and
there are no flames or sparks near the battery. Never lay objects on the battery that can short the
terminals together. If battery acid gets in your eyes, immediately seek first aid. If acid gets on your
skin, immediately wash it off with soap and water.
• If an emergency situation arises (vehicle or Liftgate) while operating the Liftgate, release the control switch to stop the Liftgate.
• A correctly installed Liftgate operates smoothly and reasonably quiet. The only noticeable noise
during operation comes from the power unit while the platform is raised. Listen for scraping, grating and binding noises and correct the problem before continuing to operate Liftgate.
• Use only Maxon Authorized Parts for replacement parts. Provide Liftgate model and serial number information with your parts order. Order replacement parts from:

PERIODIC MAINTENANCE
!
WARNING
Never operate the Liftgate if parts are loose or missing.
NOTE: Make sure vehicle is parked on level ground while performing the
maintenance checks.
Quarterly or 1250 Cycles (whichever occurs first)
Check the hydraulic fluid level in the pump reservoir. Refer to the CHECKING HYDRAULIC
FLUID procedure in the PERIODIC MAINTENANCE section.
If hydraulic fluid appears contaminated, refer to the CHANGING HYDRAULIC FLUID
procedure in the PERIODIC MAINTENANCE section.
Keep track of the grade of hydraulic fluid in the pump reservoir and never mix two different
grades of fluid.
Check all hoses and fittings for chafing and fluid leaks. Tighten loose fittings or replace
parts as required.
Check electrical wiring for chafing and make sure wiring connections are tight and free of
corrosion. Use dielectric grease to protect electrical connections.
Check that all WARNING and instruction decals are in place. Also, make sure decals are
legible, clean and undamaged.
Check that all bolts, nuts, and roll pins are in place. Make sure roll pins protrude evenly
from both sides of hinge pin collar. Replace fasteners and roll pins if necessary.
Pump EP chassis grease in each lube fitting on the cylinders and arms until grease
starts oozing from ends of the bearings. The lubrication diagram on the PERIODIC
MAINTENANCE CHECKLIST SHEET shows where to find the lube fittings. Wipe off
excess grease with a clean lint-free cloth.
CAUTION
Damaged cylinder seals and contaminated hydraulic fluid can result from painting the polished portion of the cylinder rod. To prevent damage, protect the
exposed polished portion of the cylinder rod while painting.
Check for rust and oily surfaces on Liftgate. If there is rust or oil on Liftgate, clean it off.
Touch up the paint where bare metal is showing. MAXON recommends using aluminum
primer touchup paint.
Semi-annually or 2500 Cycles (whichever occurs first)
Visually check the platform hinge pins for excessive wear and broken welds. See PARTS
BREAKDOWN section for replacement parts. Also, do the Quarterly or 1250 Cycles
maintenance checks.

platform. Use this procedure for replacing torsion spring on the LH side.
1. If platform is on the ground, manually
fold flipover onto platform.
PLATFORM
11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713
2. Fold platform and flipover to rest on
lift arms (FIG. 18-1).
FIG. 18-1
3. Raise platform to a convenient work height
to gain access (FIG. 18-1). There should
not be tension on the torsion spring in this
position.
!
CAUTION
To prevent injury and equipment
damage, make sure there is no
tension on torsion spring before
removing hinge pin.
4. Drive out the roll pin from pin collar on
the platform hinge bracket. Drive the
platform hinge pin outboard from the
shackle just enough to free the torsion
spring and bushing (FIG. 18-2).
Remove torsion spring.

1. Make sure platform is at ground level. Unfold
the platform and flipover. As the platform first
touches the ground, shackles and tip of flipover
must touch the ground at the same time (FIG.
22-1). If shackles and tip of flipover touch the
ground at the same time, RAISE platform to bed
height. Tip of flipover should be above bed level
(FIG. 22-2). If indications are correct in both
cases (FIGS. 22-1 & 22-2), Liftgate is installed
correctly and no adjustment is needed. If indications are incorrect, continue with instruction 2.
NOTE: If tip of flipover touches first (FIG.

DECALS: TE-25DC & TE-33
NOTE: Preferred decal layout is shown. Decals on the Liftgate are attached at the
factory. If vehicle does not permit this layout, decals in the manual and decal kit
must be applied so that they are easily visible when approaching vehicle to
operate Liftgate. Use good common sense when locating these decals on
vehicle.
NOTE: Ensure there is no residue, dirt or corrosion where decals are attached.
If necessary, clean surface before attaching decals.
