MAINTENANCE
Before all the repairs, service work and adjustments always lock the main
switch of the device.
The construction of the equipment is simple and thus does not require
costly maintenance. It is necessary to keep it clean, draw up loose bolts
regularly control the wear of the anti-skid surface of the rollers and in the
case of larger wear to replace this material or replace the set of rollers.
Lubrication
The oil in the gearboxes does not have to be replaced until after 10.000
hours of service. The used gearbox lubricant is synthetic oil AGIP TELIUM
VSF320. Flange and ball bearings have to be refilled annually using a
lubricant grease (for example SKF LGMT2 or LKMT3).
If you are changing the lubricant, following instructions apply:
1.
Remove the cover plates, chain tension assemblies and motors.
2.
Lubricate the bearings of the rollers by pumping the grease through
into the bearings.
3.
Lubricate bearings of the motors once a year. Lifting the rollers
allows a better access to the bearings.
4.
Lubricate the chain with a suitable oil or a special grease at least
once a year.
5.
Check the oil level in the gearbox.
6.
Bolt the cover plates on.
Warning:
The lubricating oils and grease are all oil base products and
to protect the environment it is important to prevent them leakage into
the pit. To avoid any possible adverse skin reaction, always use protective
gloves or barrier creams when working with oils and greases.
Consult the lubricant supplier/manufacturer if in doubt.
Chain tension adjustment
It is necessary to watch the wear of the chain and after its elongation to
replace it for a new one before the chain wheels are damaged. The chains
are pre-stretched and need very little adjustment. They are adjusted by
moving the front or rear roller or the motor.
1.
Remove both cover plates of the roller units.
2.
Check the chain tension, it should not deflect by more than 5 mm.
3.
Tighten the chain by moving one of the rollers away from the other.
Loosen the bolts holding the bearing. Tighten the chain by turning
the adjustment bolts, and re-tighten the bolts.
4.
Bolt the cover plates back on.
