MAINTENANCE
WARNING!
Before you remove the power meter from the line, check that the hydraulic system has
been depressurised. Failure to follow this instruction may cause serious physical injuries
or death and/or material damage.
Pressure release
Before starting work:
mobile hydraulic systems must be depressurised,
vehicle drives must be shut down,
hydraulic systems must be shut off,
hydraulic accumulators must be shut off and relieved on the pressure side.
Please note:
Be careful of any residual pressures caused by trapped volumes of fluid, e.g. between
valves and cylinders. They should be released by operating an adjusting lever or valve.
The pressure release should be checked, e.g. using a pressure gauge.
Dismantling and cleaning the volume flow meter
1.
Remove the power meter from the line. Remove any excess pipelines/screw connections
from the power meter.
Please note! It is not necessary to remove the transparent dust protection casing (15)
(see Table
1, page 4)
from the power meter in order to remove the meter from the line. If you wish to
remove the dust protection assembly from the volume flow meter, see "Removing the dust
protection” on
page 17
.
2.
Wipe down the whole of the surface of the volume flow meter thoroughly with a mild
cleaning agent or isopropyl alcohol.
CAUTION!
Do not use any aromatic hydrocarbons, halogenated hydrocarbons, ketones or ester-based
liquids to clean polycarbonate surfaces. Failure to follow this instruction may cause the
power meter to be damaged.
