8. CHECKS:

8.1 First start-up checks

Before starting the machine check the following:
- Check that all the oil plug are in the correct position (see
paragraph 2.2 "configuration").
- Check that all oil levels are correct.
- Check that all the grease guns are full of grease.
- Check that the operating pressure (see table on the right) is
sufficient to fully open the multi-disk brake to avoid overheating
and any premature wear of brake disks.

ATTENTION: Given the type of brake, the operating pressure
should never drop below the minimum brake opening pressure
to avoid the braking action.
ATTENTION: The gear units and any multi- disk brakes are
shipped without oil. The customer is responsible for filling such
devices (see lubrication chapter paragraph 7).
- Check that all the bolts with ISO metric threads are correctly
tightened (see table "torque setting values").
Gearboxes can be operated at ambient temperature ranging from
-20∞C to +50∞C. When starting a gearbox at low temperature
(-20∞C to 0∞C) the efficiency can be lower due to extreme
viscosity of the lubricant. In such cases idle running or limited
loading is recommended for some minutes.
For operations at ambient temperature below -20∞C, it is
advisable to provide adequate countermeasures, such as hoods
or oil pre-heating device.

8.2 No-load tests

- After a brief period of operation (5-10 minutes) check the oil
levels under no-load conditions, topping up those levels which
have gone down check that nuts and bolts of the various
attachments are properly tightened.
- Check that the brakes lock and release at the right time and all
operate correctly.

9. MAINTENANCE:

Introduction
Maintenance can be "routine or unscheduled".
ATTENTION: All maintenance activities must be carried out
under safety conditions.

9.1 Routine maintenance:

The operator is responsible for routine maintenance and must
carry out the following activities.
- After a brief operating period of about 100 hours (breaking-
in), change the oil in the gear unit and the multi-disk brake (if
installed) and wash the interior of the unit with cleaning liquid.
- Check that there are no metallic parts with unusual dimension
in the magnetic plug of the gear unit and in any multi-disk brake.
- Change the oil in the gear unit while it is hot so that it is easier
to drain.
