4. CONTROL AND MAINTENANCE
4.2
Visual Inspection
There must be controlled whether there is leaking or not in gear unit.
There must be controlled that if there is oil filled or not in gear unit. Should be controlled that if there is any
damage in gear unit's items and whether if the connection spots are rusted.
Also must be controlled that if any cracks could emerge in hose connection lines and in rubber wedges.
Leakproofing likes of dripping of gear unit's oil or dripping of cooling water and in damages and cr
acks, repair
of the gear unit must be provided. Like these situations please get in contact with CHIARAVALLI.
Because of the storage and carrying, before the operation of gear unit and during at first operation, low
amount of grease could flow out from bearing, thi
s type of oil leak could not create any technical failure, the
safety of gear unit and bearing operation could not be effected.
NOTE!
Must be sured that there is not air in hydraulic circuit.
4.3
Check for Running Noises
The emerge of unusual operation voice or vibrations in gear units could mean damages. In this type of situations,
the gear unit must be stopped and overall revision must be made.
4.4
Control of the Lubricant and Lubricant Level
- Regular oil level controlling must be made.
- The electrical connection of motor must be cut and must got into safety form to prevent for reactivating.
- Must be waited until the gear unit got cooled.
- If the mounting position is changed, the section of 'the mounting of gear unit' must be got into attention.
- A little amount of oil must be taken out of the oil drain plug. The quality of oil must be controlled.
- The oil must be changed when the sign of extremely oil pollution is seen.
4.5
Changing The Oil
To prevent the emergence of the danger of burning, must be waited until the gear unit got cooled. The oil level,
draining and position of ventilation plugs are dependent on mounting position. For the mounting position, related
pages from catalagoue could be seen. When the oil-changing process, the gear unit should be at operating
temperature. The electric connection of motor driving unit must be cut and got into safety for re-activation.
NOTE!
Because of the coldness of oil will affected the flowing and venting,
the gear unit must not
be cooled fully.
NOTE!
Above articles must be done respectively during in the oil change of the hydraulic brakes.
Because the oil of the hydraulic brake is different from the gear unit.(ISO VG 32)
If the gear unit mounted vertical,the oil change must absolutely made from the expansion tank which is
attached to gear unit.
After 100 hours,first oil change must be made
