DEMOUNTING THE MOTOR
Take into consideration the following things when
demounting the motor for service or replacement:
µRelease the pressure in the hydraulic lines and let
the motor cool down.
µDisconnect all the hydraulic lines from the motor
and plug all openings and hoses.
µDemount the motor and lift it away from its
position.
µClean the outside of the motor thoroughly, but do
not use any solvents.
µProtect the cleaned motor from corrosion.
µIf possible, drain all the hydraulic fluid from the
motor.
Information!
Dispose of hydraulic fluid should be done appropriately.
STORING THE MOTOR
During short term storage of the motor, the following
should be taken into consideration:
µCover any pressure openings and open threaded
holes with suitable caps.
µProtect the unpainted surfaces from dirt and
moisture.
µStore the motor in a dry place with relatively stable
temperature.
µThe motor should not be stored in a same place as
substances with aggressive corrosive nature
(solvents, acids, alkalis and salts).
µThe motor should not be exposed to strong
magnetic fields.
µThe motor should not be exposed to strong
vibration.
Information!
For long-term storage (over 9 months) the following
additional actions are recommended:
µDamages to surface paint must be repaired.
µProtect the unpainted surfaces with suitable anti-
corrosion treatment.
µFill the motor completely with hydraulic fluid.
If these instructions are followed, the motor may be
stored for approximately two years. However, as
storage conditions do have a significant effect, these
times should only be considered as guide values.

COMMISSIONING PROCEDURE
Ensure that the following things are in order before
starting a new or replaced motor:
µThe hydraulic circuit of the motor is flushed.
µMotor is installed appropriately.
µAir bleeding procedure is carried out.
µThe reservoir of the hydraulic system is full.
During the initial stages use, also take the following
things into consideration:
µDo not run the motor immediately with full power.
Increase the load and speed of rotation gradually.
µObserve the motor and the hydraulic system for
external leaks or abnormal noises during the
commissioning procedure.
µStart the motor break-in.
Information!
During all installation and service procedures, plug any
open ports and hoses.
When filling the reservoir, add hydraulic fluid through a
filter.
Attention!
Do not start the motor, if the air bleeding procedure has
not been carried out.
Stressing an unused motor with full power may cause
premature wear or failure of the motor.
AIR BLEEDING PROCEDURE
Air bleeding procedure is carried out to fill the housing
of the motor completely with hydraulic fluid. Air is
removed from the housing with air bleeding screws as
follows:
µLocate the air bleeding screws of the housing and
turn the motor to a position in which the screw is at
its topmost position.
µMake sure the drain line of the motor is connected.
µFeed hydraulic fluid into the motor with low
pressure throughout the procedure.
µUnscrew the air bleeding screw by half a turn and
let air escape from the housing.
µClose the screw when only hydraulic fluid is
pouring through it.
µTighten the screw to a torque of 39 ± 3 Nm.
The location of the air bleed screws is given in the
product datasheet.
Information!
If feed pressure is not available, fill the housing
manually by pouring hydraulic fluid in the motor
through the topmost opening of the housing.
FLUSHING THE HYDRAULIC SYSTEM
Prior to connecting the motor as part of the hydraulic
system, the hydraulic circuit of the motor must always
be flushed by circulating hydraulic fluid through a filter
installed in place of the motor.
The flushing is carried out by circulating hydraulic fluid
through the entire system with a minimum pressure for
at least an hour.
µAfter flushing, renew all filters.
Information!
Flushing the hydraulic system should also be
performed after every system modification or repair.
BREAK-IN PERIOD
The motor achieves its final properties during the first
hours of use. Therefore all new and reconditioned
motors should go through an initial break-in period.
Things to be considered during break-in period:
µThe break-in period should last for at least first
eight hours (8 h) of use.
µThe power output should remain under 50 % of the
maximum power capacity of the motor.
µThe power output is limited by limiting the working
pressure, the speed of rotation or both.
µThe working pressure should be limited so, that
pressure peaks which last over two seconds (2 s)
remain under 75 % of the permissible values.
Information!
During the break-in period, the moving parts of the
motor wear against each other so, that the wear of the
parts sets to a stable state for the entire service life of
the motor.
USE
Things to be considered during use of motors:
µCheck the screw connections tightening torque
and hydraulic connections regularly.
µDo not use pressure cleaning directly between the
shaft flange and housing of the motor (the shaft
seal area).
µAvoid situations in which the motors are
completely submerged in water or mud.

HYDRAULIC FLUID
HYDRAULIC FLUID TYPE
Black Bruin hydraulic motors are designed to work with
hydraulic fluids based on mineral oil. Consider the
following requirements when choosing hydraulic fluid:
µHydraulic oils in accordance with ISO 6743-4 are
recommended to be used.
µMotor oils in accordance with API-grades SF, SG, SH
and SL may also be used.
µFire resistant hydraulic fluids HFB and HFC or
similar may be used under certain circumstances.
HYDRAULIC FLUID PROPERTIES
Requirements concerning the hydraulic fluid
properties:
µThe recommended fluid viscosity range for
constant use is 25 - 50 cSt.
µThe minimum permissible intermittent viscosity is
15 cSt.
µThe maximum permissible viscosity during motor
startup is 1000 cSt.
µThe viscosity index must be at least 100.
µThe water content of hydraulic oil should be less
than 500 ppm (0,05 %).
µThe hydraulic fluid must reach score 10 on a wear
protection test FZG A/8,3/90 in accordance with
ISO 14635-1 (DIN 51354)
µThe effect of the additives improving the viscosity
index can decrease during operation.
Information!
Temperature has a significant effect on the viscosity
and the lubricating capability of the hydraulic fluid.
Take into consideration the real operating temperature
when defining the fluid viscosity.
The need for service and the overall service life may be
improved by using hydraulic fluids with higher
viscosity. In addition higher viscosity may improve the
running smoothness.
HYDRAULIC FLUID CLEANLINESS
Hydraulic fluidmust fulfill cleanliness level 18/16/13 in
accordance with ISO 4406 (NAS 1638 grade 7).
Information!
The purity of the hydraulic fluid has a significant effect
on the need for service and the overall service life of the
motor.
OPERATING TEMPERATURE
The operating temperature means the internal
temperature of the motor. Take into considerations the
following requirements for the operating temperature:
µFor improved service life, avoid over 70 °C
(158 °F) operating temperature.
µThe highest permissible intermittent operating
temperature is 85 °C (185 °F).
µThe lowest permissible operating temperature is -
35 °C (-31 °F).
µThe temperature difference between the motor
and the hydraulic fluid should be under 60 °C
(140 °F).
The operating temperature may be measured from the
hydraulic fluid returning from the motor. Take into
account the temperature of hydraulic fluid returning
from the drain line and from the return line (A or B).
