Maintenance

214815

Check hoses and connections for wear and leakage at

regular intervals. Make sure that hoses have sufficient

clearance and do not scrape against other components.

Replace damaged hoses and tighten all connections.
The cylinders are double-acting. They must always be

maintained in good condition for optimal function. Leaks,

internal or external, affect performance and may be

hazardous.
This loader requires a hydraulic system that works at high

pressure. Only use replacement parts approved by the

manufacturer.

6.2.2. Repair/replacement of hydraulic

components

6.2.2.1. Hydraulic cylinders

The removal, repair and installation of hydraulic cylinders

require special tools to prevent damage to internal

components. We recommend you to have your cylinders

repaired by an authorized dealer.

6.2.2.2. Hydraulic hoses

If a hose ruptures, correct the problem immediately. When

replacing parts, only use original spare parts in order to

restore the machine to its original design.

IMPORTANT:

If the hose

CANNOT

be replaced safely,

the loader must be lowered to the ground and depressurised.

After replacing the hose, perform a lifting exercise before

performing a lowering exercise. Run all loader functions

several times to remove air from the system. Air in the

system can cause jerky motions.

6.3. Checking the loader and subframe

hardware

CAUTION:

Check the loader and subframe for cracks,

loose screws or other damage that can affect

functioning negatively and result in personal

injury. When replacing parts, only use original

spare parts in order to restore the machine to

its original design. For continuous operation,

perform an inspection every 50 hours of

operation.

Operating hours = the time that the loader is in motion.
Check that all subframe hardware are tightened to the

specified torque, first after 10 hours of operation and then

every 50 hours of operation thereafter.

6.3.1. Torque

Tighten all the subframe hardware on the loader and all

fixed components according to

6.3.1.1. Table - Torque

. If

another torque is specified in the installation instructions,

that torque should be used instead of the torque listed in the

table.
