1 INTRODUCTION
The MSR 2 speeds spindle gearbox will give you complete satisfaction if all of the following
mounting, operating and maintenance instructions are respected.
This gearbox is delivered:
Fully tested (leakage, speed change motoreducer, noise level, vibration, temperature)
Ready to be mounted
1.1 Warnings
1.2 Gearbox identification
Each unit can be identified through its identification plate and the serial number indicated on it. The
serial number must be given for any correspondence on a particular unit.
1.3 Long term storage
Each gearbox is delivered wrapped and greased for 1 month anti-corrosion protection. Gearboxes
which are not installed shortly after receipt should be stored in a dry atmosphere with temperature
between 0°C & 40°C. The unit must be filled completely with oil for storage.
WARNING! LUBRICATION REQUIREMENTS.
The MSR is delivered WITHOUT OIL: refer to lubrication chapter in this
manual to respect all lubrication requirements.
any damage due to incorrect lubrication will void the warranty.
