Checking the Lubricant in
the Gearbox
Service Interval:
Every 50 hours
The gearbox is designed to operate on either
petroleum or synthetic SAE 80W–90 gear lube.
Although the gearbox is shipped with lubricant from
the factory, check the level before operating the cutting
unit. The gearbox capacity is 0.33 L (11.15 fl oz).
1.
Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
2.
Remove the breather plug from the top of
the gearbox (
) and ensure that the
lubricant is between the fill marks on the lower
part of the breather plug. If the lubricant level
is low, add enough lubricant until the level is
between the marks.
