WARNINGS
Before setting at work, carefully read instructions for use and follow them!
Only qualified personnel, that has carefully read instructions, is allowed to operate on
BF gearboxes.
Responsibility and warranty are excluded if:
•Instructions for use are not followed
•The gearbox is not operated in a correct way
•Maintenance is not performed correctly and regularly
•Functional changes of any type are brought without manufacturer’s consent
•Original spare parts are not used
NOTE:
This symbol highlights critical operations:
•a wrong procedure can cause damages to the gearbox
•non observance can impair operator’s safety
All gearboxes are delivered without oil.
Always make sure that a proper lubrication is applied to the gearbox,
according to the ordered code.
Operating the gearbox for long periods in high speed mode can produce a local damage on
the engaged teeth of the gears. This may turn in noisy operation.
Thus, it is necessary to operate the gearbox in low speed mode for a few seconds after
max.1 hour operation in high speed mode, in order to change the engagement position and
to allow the lubrication of the gears.
All gearboxes need to work in an area:
- without the presence of fluids as coolant and oils (the actuator is not
water proof)
- without the presence of steel chips
