Installation and Maintenance Manual, Compact CA
Place the motor as shown in figure 4.1, fill the
motor with filtered oil in the following order: D1,
A1, B, C1. See 2.3, "Filtration".
Take extreme care to ensure that no contami-
nation enters the motor.
Seal connections A and C with the cover plate
fitted to the connection surface at delivery.
Check that the O-rings or rubber seals are in
position in the cover plate.
Fit the plug to D1, D2 and D3, the table below
states the amount of oil needed to fill the vari-
ous types of motors.
4.2 Before commissioning
Check the following points before commission-
ing the motor, i.e. before starting the first time:
- Check that the motor is connected to give
the correct direction of rotation (see 3.2 "Oil
connections" and 3.2.1 "Direction of rotation
of motor shaft").
- Select the hydraulic fluid in accordance with
the recommendations (see 2.3 "Choice of
hydraulic fluid").
- Fill the motor housing with hydraulic fluid via
a filter into the drain outlets D1, D2 or the
vent hole (depending on how the motor is
mounted).
- Check the drain line to ensure that exces-
sive pressure does not build up in the motor
housing; see 3.1 "Mounting instructions" and
3.2.2. "Draining and venting the motor".
- Check that the motor is protected from over-
loads (see 1.1 "Motor data").- Check that
the charge pressure conforms to the charge
pressure curve (see 2.1 "Recommended
charge pressure").
- Check that all hydraulic couplings and plugs
are properly tightened to prevent leakage.
- Make sure that the torque arm is sufficiently
fastened, see 3.1.3.
Maintenance
4.3 Commissioning
- During initial starting and the period immedi-
ately after it, any hydraulic installation must
be regularly and carefully checked at frequent
intervals.
- The working pressure and charge pressure
must be checked to ensure that they corre-
spond to the contracted values.
- The pressure in the drain line measured at
the motor must be less than 3 bar (43.5 psi).
This pressure limit is important for the life of
the motor seals.
- If leakage occurs, correct the fault and carry
out new measurements.
- Check all lines, connections, screws etc and
correct if necessary.
- Check other possible leakage points and
replace faulty parts.
- During the start up period, dirt particles in the
system are removed by the filters. The filter
cartridges have to be changed after the first
100 working hours and after that according to
the maintenance chart see 4.4 note to check
the "filter clogged" indicators.
NOTE:
It is important that the pressure is limited
to 250 bar (3626 psi) when starting up the
motor.
A not run-in motor in combination with dirt
particles in the oil can badly affect the sliding
surfaces in the motor. This is valid during the
first 100 working hours.
