Comply with the following WARNINGS and SAFETY INSTRUCTIONS while maintaining
Liftgates. See Operation Manual for operating safety requirements.

WARNINGS

• Do not stand, or allow obstructions, under the platform when lowering the Liftgate. Be sure your

feet are clear of the Liftgate.

• Keep fi ngers, 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

11921 Slauson Ave. Santa Fe Springs, CA. 90670 [phone] FAX [phone]

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.

!

WARNING

SAFETY INSTRUCTIONS

• Read and understand the instructions in this Maintenance Manual before performing mainte-

nance on the Liftgate.

• 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 fl ames 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 fi rst aid. If acid gets on your
skin, immediately wash it off with soap and water.

SAFETY INSTRUCTIONS

• 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:

Unfasten latch and remove the pump cover
(FIG. 9-1) .

2. Remove threaded fi ller cap (FIG. 9-2).

Check the hydraulic fl uid level in reservoir.
hydraulic fl uid level should be 1” below the
top of fi ller hole (FIG. 9-2). If needed, add
hydraulic fl uid to fi ll the reservoir to the
level shown in FIG. 9-2.

3. Reinstall fi ller cap (FIG. 9-2).

activated.If voltage is low, recharge battery.
If no voltage is at coil, check connections on

replace switch. Check battery, recharge or
replace.

5. To check “DOWN” valve coil, hold screw
driver 1/8” from nut at end of coil (FIG.
