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.
3. 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 F1
on the shaft end housing) and fill the motor
with hydraulic fluid.(See Fig. 4.3 and 4.3a).

4.4 Periodic maintenance
When a hydraulic system has been in service
for some time, it must undergo periodic
maintenance 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:
