8. Service and Maintenance

8.1 Maintenance Safety

Before performing any maintenance procedure, place the
machine in a Safe Condition to work on.

•

Empty material from grapple.

•

Lower grapple to ground.

•

Turn skid steer engine off.

•

Move controls to verify there is no movement.

• Follow good shop practices:

-

Keep service area clean and dry.

-

Be sure electrical outlets and tools are properly
grounded.

-

Use adequate light for the job at hand.

• Never operate the engine in a closed building. Exhaust

fumes may cause asphyxiation.

• Never work under equipment unless it is blocked or

supported securely.

• When performing any service or maintenance work

always wear appropriate PPE.

• Where replacement parts are necessary, genuine

factory replacement parts must be used to restore your
equipment to original specifications. The manufacturer
cannot be responsible for injuries or damages caused by
use of unapproved parts or accessories.

• Keep hands away from moving parts. NEVER grease or

work on the grapple when it is moving.

• Always use proper tools, that are in good condition. Make

sure you understand how to use them, before performing
any service work.

8.2 Greasing

All LXG grapples use composite bearings in the grapple head
assembly. LXG420R, LXG430R, and LXG430RP models use
composite bearings on the upper hanger assembly. Models
LXG420S and LXG430S use them on the entire hanger
assembly and the pivot.

These bearings are made of a self-lubricating composite
material designed for heavy loading. The only exception is
the hanger bearing on LXG420R, LXG430R and LXG430RP
models with the rotator.

For the Rotator Hanger Bearing, use an SAE multipurpose, high-
temperature grease with extreme pressure (EP) performance.
Also acceptable is an SAE multipurpose lithium base grease.

Lubricate Rotator Hanger Bearing every 50 hours of use.

1.

Use a hand-held grease gun. Wipe grease fitting with a
clean cloth before greasing, to avoid injecting dirt and grit.

2.

Replace and repair broken fittings immediately.

3.

If fitting does not take grease, remove and clean thoroughly.
Also, clean lubricant passageway. Replace fitting if
necessary.
