Transmission Maintenance

Oil Change
Most homeowners with gardens do not have
the tools or experience needed to change the
transmission oil. The transmission probably
has a longer life than the rider itself, which
means that being able to change the oil is not
of major concern to the average consumer.
The lifespan of the transmission increases,
however, if the oil is changed.
When the rider is used commercially, we
recommend changing the oil first after 50
hours of use and then every 200 hours or at
least once a year.
IMPORTANT INFORMATION
Used oil is an environmental hazard and
must not be disposed of on the ground or
in nature; it should always be disposed of
at a workshop or appropriate disposal
location.
Avoid skin contact; wash with soap and
water in case of spills.
Remember cleanliness. Follow the
instructions in the hydraulic system chapter.
