THE MACHINE MUST BE FULLY DISCONNECTED BOTH ELECTRICALLY
AND PNEUMATICALLY BEFORE UNDERTAKING EITHER ROUTINE OR
SPECIAL MAINTENANCE WORK.

THIS PROCESS SHOULD BE CARRY OUT BY WELL EDUCATED WORKER.
6.1 Routine maintenance:
The maintenance below is carried out daily before running the machine, and
consists of:

Before starting the machine, check that there is nothing obstructing movement of
the station and motors that could lead to damage or personal injury.

Check that pressures are correct.

Make sure that all micros (the rods) are correctly positioned (vertically, waiting to
contact the work piece), that they are firmly tightened and that they move as they
should.

These maintenance points are carried out at the close of each working day:

Clean the work zone.

Make sure that the main supply cable shows no signs of cuts or burning.

Check the condition of cutters and tracers.

Check the oil level in the air service unit lubricator reservoir.
6.2 Special maintenance:
This maintenance is carried out weekly:

Carry out all routine maintenance operations.

Check the safety of the electrical installation.

Check locking of mechanical components.

Examine cable insulation, operation of devices and continuity of protective
conductor.

Check the cutters for wear.

Clean the chain wheels and rubbers with a cloth dampened with neutral solvent
(that damages neither silicon nor rubber). Do this after lifting the presser, having
completely stopped the machine.

Use a little machine oil (SAE-10) and a cloth to clean the tracer bearings, then dry
off and apply a thin film of grease.

Check the condition and tension of the transmission pulleys inside the cabinet
under the tray and glue pot.

Transmission set: This refers to all the equipment under the glue pot whose
function is the synchronised transmission of chain movement to the glue roller,
band feed system and first press roller.
Belt condition and tension needs periodic checking. The flat belt is tensioned by
simply loosening the fixing screws and moving the angle bevel box to achieve the
required tensioning.
