10 Maintenance schedule
i
Before conducting maintenance work, prepara-
tions must be made to ensure that during mainte-
nance and repair work there is no risk to the safety
of people working on or around the device and
also that there is no risk of damage to equipment
being used on or around the play detector.
To guarantee the utmost availability and to ensure that
the device remains functional, maintenance work con-
tracts are organised between our clients and their lo-
cal retailers.
A service must be performed at regular intervals of 3
months through the operator in accordance with fol-
lowing service manual. If the play detector is in conti-
nuous operation or in a dirty environment, the mainte-
nance rate must be increased.
During daily operation the play detector must be clo-
sely observed to ensure that it is functioning correctly.
In the case of malfunction or leakage the technical
service must be informed.
10.1 Maintenance schedule
• Before beginning any maintenance work isolate the
power supply. Secure the main switch (lock it).
Secure the danger area around the play detector.
• Clean the piston-rod using compressed air.
• Clean and lubricate the moving parts device (hinge
bolts, sliding pieces, sliding surfaces) replace if ne-
cessary.
• Grease the piston rods with a high capacity lipid.
• Grease the lubricate nipples with a multipurpose li-
pid. (example: Auto Top 2000 LTD. Agip).
• Check the hydraulic tubes for leakage.
• The hydraulic oil has to be changed at least once a
year. To change the oil. Empty the tank and re ll with
clean oil, approx. 11 litres are needed.
Use an ATF-Suf x hydraulic-oil (OEST Company ) if the
ambient temperature is under 5 degrees centigrade.
After  lling, the hydraulic oil must be between the up-
per and lower markings of the oil level gauge.
!
Remove the old oil according to the appropriate
regulations.
• Check all welded joints for cracks on the play detec-
tor.
If any cracks are found on the play detector cease
use immediately. Switch-off and secure the main
switch (lock) and call the service partner.
• Check all surfaces and repair if necessary.
Damage to external surfaces, must be immediately
repaired.
If theses repairs are not made immediately, perma-
nent damage to the powder-coated surface may
result. Repair and clean damaged areas with an ab-
rasive paper (grain 120). After this is complete, use a
suitable paint (observe the RAL Number).
• Check the zinc surface and repair it with a suitable
tool. Use abrasive paper (grain 280).
White rust can result from moisture laying in certain
areas for long periods of time. Poor aerating can also
result in rust formation.
Rust may result from mechanical damage, wear, ag-
gressive sediments (de-icing salt, liquids) or insuf ci-
ent cleaning.
Repair and clean these areas with abrasive paper
(grain 280). After this is complete, use a suitable paint
(observe the RAL Number).
• Check the electric cable and channels for Damage.
• Check condition and function of hand lamp/remote
hand lamp.
• Check the turning moments of the screws.
