GEARBOX OIL LEAKAGE
NOTICE
Major oil leakage from the gearbox shaft seal
area is not acceptable and could cause the gearbox
to fail due to lack of lubrication and cooling. It is
the operators responsibility to check the gearbox
oil level per the Lubrication Service Table.
Before checking gearbox oil level, shut down the
shredder for a couple of hours to allow the oil to drain
back into the reservoir for the most accurate reading.
Proper oil level should be between the full and add
lines on dipstick. When oil is needed, add through the
dipstick tube.
NOTICE
DO NOT OVERFILL. Lab tests have proven that
overfilling the gearbox can dramatically increase
the gearbox operating temperature. In extreme
cases this can overheat the oil, reducing its lubri-
cating and cooling properties, and eventually
cause shaft seals to deteriorate and fail. Over-
heated oil has an obvious burnt smell; drain it and
refill with new oil. Overfilling gearbox oil can void
the warranty.
The gearbox should not require frequent servicing of
oil. It is not designed to consume or lose large amounts
of oil. If oil needs to be added frequently, troubleshoot-
ing the cause is required (see section below).
