Maintenance
Motor
If the motor is to be stored stationary for a
longer period than about 1 month, it must be
protected from internal rust. This can be done
as follows:
1. Mix anti-rust additive with the hydraulic
fluid of the system. Use 5% of Rust Veto
Concentrate (manufactured by E F
Houghton & Co, Philadelphia, USA). This
additive gives rust protection for up to
about 1 year, after which time the motor
must be turned a few revolutions.
. If no additives are used, the motor must
be regularly turned a few revolutions.
. If it is not possible to turn the motor, plug
all connections, open drain outlet D1 or D
on the port end housing (or if the motor is
mounted vertically, Flushing connection F
on the connection block) and fill the motor
with hydraulic fluid.(See Fig. 4.).

4.4 Periodic maintenance
When a hydraulic system has been in service
for some time, it must undergo periodic mainte-
nance and servicing at intervals which depend
on the equipment and the type of duty.
This periodic maintenance must include the
following operations:
- Check the hydraulic system for leakage.
Tighten the screws, replace faulty seals and
keep the drive clean.
- Inspect and clean all air, oil and magnetic
filters; replace all filter cartridges for which
a filter clogged indication has been given;
inspect tank, pump, filters etc. and clean if
necessary.
- Check the pressure and temperature of the
hydraulic fluid and carry out routine opera-
tions. Adjust valves etc. if necessary.
- Check the hydraulic fluid; see the Section
headed "Oil".
- Check that no dirt or other contaminations
enter the system during inspection.Check
that the outside of the hydraulic motor in an
installation is kept free of dirt; thus leakage
and faults will be detected earlier.
- We recommend that a running log be kept
and that planned inspections are carried out
at set intervals.
- Maintenance checks and operations are as
follows:
