IOM Manual VF-W_ATEXgb - Translation of original instructions in Italian - Rev 03_0 - 30/09/16
Unless they have backstop devices, gearboxes may reverse direction. If there is any risk of
uncontrolled movement occurring in the event of a power failure (for example in load lifting
applications), measures must be put in place to prevent such movement occurring (for example by
using motors with brakes that engage automatically if the power fails).
If the gearbox is installed in a position that cannot be reached from the floor, the constructor of the
plant or machine in which it is installed must provide, as necessary, suitable means for accessing
a position from which the gearbox can be serviced.
The user is responsible for using the products recommended for the installation and maintenance
of the gearbox in an appropriate manner and in accordance with the Manufacturer’s instructions.
Before putting the gearbox into service, the user must ensure that the plant in which it is installed
complies with all applicable directives, especially those regarding health and safety at work.
The constructor of the plant or machine in which the gearbox/gearmotor is installed must protect all
rotating parts to prevent personnel coming into accidental contact and incurring a risk of crushing,
cutting or entanglement, especially if the gearbox operates automatically and in an accessible area.
●
Do not use high pressure jets of water to clean gearboxes unless they are EP versions with a seal ring
and reinforced shield.
●
Only perform work on the gearbox when it is at a standstill.
●
Protect the electric motor against accidental startup (e.g. by padlocking the main power switch or
removing the power fuses). For this purpose, also affix a notice to the motor indicating that work is in
progress on the gearbox.
●
Do not perform welding work on the gearbox. Do not use the gearbox as an earthing post for welding
operations because this could damage or destroy parts of the gear teeth and bearings.
●
Switch off the motor immediately if any changes are noticed in the normal functioning of the gearbox,
such as an abnormal increase in operating temperature or abnormal running noise.
●
If the gearbox is to be installed in a plant or machine, the constructor of the said plant or machine
is required to include the prescriptions, instructions and descriptions contained in this manual in the
operating manual for the plant or machine.
●
If the gearbox is installed in situations that are particularly hazardous to personal safety, or that could
cause serious damage to equipment, or that involve high inertial loads, vibrations, etc., such as:
- suspended installations
- motors supported exclusively by the gearbox
- output shaft with shrink disc oriented downwards
suitable safety devices, such as harnesses, safety chains and restraining systems, etc. must be
installed.
Depending on operating conditions, the outer surfaces of the gearbox may reach very high
temperatures. Risk of burns!
When draining spent oil as part of an oil change, always bear in mind that hot oil can cause serious
burns!
If the gearbox is equipped with a vent plug that incorporates a pressure relief valve, wait for the
oil in the gearbox to cool before removing the plug, and beware of possible jets of oil during
transport, lifting, installation, adjustment, operation, cleaning, maintenance, repair, dismantling
and scrapping.
Wait for the gearbox to cool before inspecting it.
