WARNINGS

SAFETY INSTRUCTIONS

• 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 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.

• 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.

• Disconnect Liftgate power cable from battery before repairing or servicing Liftgate.

• Do not allow untrained persons to operate the Liftgate.

• 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.

Comply with the following WARNINGS and SAFETY INSTRUCTIONS while maintaining

Liftgates. See Operation Manual for operating safety requirements.

• 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.

• 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.

WARNING

• Correctly stow platform when not in use. Extended platforms could create a hazard for

people and vehicles passing by.

• 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) D2.1 Structural Welding Code - Aluminum. Damage to Liftgate

and/or vehicle, and personal injury could result from welds that are done incorrectly.

SAFETY INSTRUCTIONS

11921 Slauson Ave. Santa Fe Springs, CA. 90670 (800) 227-4116 FAX (888) 771-7713

• If an emergency situation arises (vehicle or Liftgate) while operating the Liftgate, release the con-

trol 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, grat-

ing 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 num-

ber information with your parts order. Order replacement parts from:

QUARTERLY MAINTENANCE SCHEDULE

1. Do the CHECKING HYDRAULIC FLUID procedure in the PERIODIC MAINTENANCE

section.

2. Check all hoses and ﬁ ttings for chaﬁ ng and ﬂ uid leaks. Replace if necessary.

3. Check electrical wiring for chaﬁ ng and make sure wiring connections are tight and free

of corrosion. Apply dielectric grease to electrical connections.

6. Check for rust and oily surfaces on Liftgate. If there is rust or oil on Liftgate or if the Lift-

gate is dirty, clean it off. Touch up the paint where bare metal is showing.

7. Inspect the wire ropes. Check for broken wire strands and check both ends of each rope

for corrosion.

8. Check for excessive wear and broken welds. See PARTS BREAKDOWN section for

replacement parts.

9. Grease the Liftgate where grease ﬁ ttings are provided.

10. Make sure both columns are free of grease where the runners roll inside the columns.

NOTE: Small amounts of seepage from cylinder seal is normal, but if oil is gushing

from the breather or rod end, it is considered a leak.

1. To check for cylinder seal leakage, remove the cover from the main frame assembly. The

platform should cycle up and down several times.

2. If there is a leak, replace the cylinder seals. Remove the cylinder from the main frame

assembly and disassemble in a separate area. For cylinder removal, see CYLINDER

REPLACEMENT. Seal kits are available from MAXON Industries Inc. For speciﬁ c unit

and model, see pro seal kit part number unit (parts breakdown).

3. Remove the sheaves from the tops of

the column assemblies. Check the

bolts for wear in the area where the

sheave has been rotating. If the bolts

are worn, they must be replaced. For

RC-2, use P/N 202438. For RC-3, RC-

4, RC-5, and RC-6, use P/N 202465.

5. With the stops removed, the brake as-

sembly can be pulled out of the col-

umn. The wire rope end ﬁ tting can now

be removed from the upper portion of

the brake assembly. Let the wire rope

hang out over the top of the column

assembly.

4. Locate the cable. Inspect the sheaves

for nicks or chips. If they need to be

replaced, see PARTS BREAKDOWN

to obtain the correct part number.
