As with most gearboxes oil changes must be carried
out at regular intervals. Initially this should be done
after the first 50/100 working hours and then
subsequently every 500 working hours or at least
every 12 months.
For this gearbox the
minimum recommended
viscosity index is 95. Depending on the ambient
temperature of the work place the viscosity index
should vary as follows:

During oil change, we recommend that the inside of
the Gearcase is flushed out with flushing fluid
recommended by the lubricant manufacturer.
Oil should be changed when hot to prevent a build up
of sludge deposit. It is advisable to check the oil level
at least once per month. If more than 10% of total oil
capacity has to be added, check for oil leaks.
Do not mix oils of different types even of the same
make.
Never mix mineral and synthetic oils.
Service Engineers must be aware of the
dangers during an oil change involving hot
oil i.e. scalding. The Service Engineer must
also be responsible when disposing of the
discarded oil. This should be done in
accordance with local environmental
regulations.
