Maintenance and repair

DANGER

Risk of breaking hose lines due to overload or aging!

Danger to life, risk of injury!

Replace the hose lines after 6 years at the latest or if damage is visible.

Bosch Rexroth offers a wide range of repair services for maintenance of the drive

module. Please send any enquiry to your nearest Bosch Rexroth service center or

directly contact the headquarters. For the addresses, please refer to

www.boschrexroth.com.
Maintenance tasks (inspection, service, repair) must be defined in terms of

component-specific requirements, operating conditions (pressures, temperatures,

ambient conditions) and use (duty cycle, cycle times, shift operation.

See machine manufacturer’s operating instructions.
Within this framework, a visual inspection is to be undertaken to detect obvi-

ous faults:

Incomprehensible notes or warning signs

•

Leaks

•

Loose and/or missing components

•

Indication of the application of external force

•

Maintenance documentation

10.1

It is recommended that the results of the inspections and the derived measures

required be documented,

So that considering functionality and economy, the service intervals can be

•

adjusted to the actual operating conditions,
As they offer the possibility of early fault recognition thanks to comparative

•

evaluation (preventive maintenance).

Any negative trend of the test parameters e.g. oil temperature, replacement

intervals of the filter elements or noise may be an indication of changes. The

error tables (see Chapter 15) may provide help in minimizing this problem.

Gradual temperature increases and/or shorter filter replacement intervals may

be an indication of possible wear at pumps, control edges, seals and aging of

the hydraulic fluid and means that an inspection should be undertaken of all

components under consideration.

An immediate high temperature increase is an alarm signal and requires an

immediate inspection of the machine.

Inspection, maintenance, repair

10.2

Recommendations are based on the following: A Central European climate and

an environmental load as is usual in metal-processing companies.
