■ MAINTENANCE CHART
■ GEARCASE LUBRICATION
With the exception of oil leaks or contamination,
the RedMax Sweeper's oil filled gearcase is
designed to last the life of the machine under
normal use:
• It is not necessary to add oil or to "top off" the
gearcase under normal operating conditions.
• For continuous heavy-duty applications, (such
as where the machine will be stopped only
during refueling), RedMax recommends
replacing RedMax Sweeper gearcase oil every
40 hours of operation.
■ REPLACING THE GEARCASE OIL (MA1)
Warm the gearcase oil by running the RedMax
Sweeper at varying speeds for approximately 8-10
minutes, and then switch the engine to "OFF" and
disconnect the spark plug wire at the engine. Use
the following procedure to remove and replace all
gearcase oil.
Maintenance, replacement, or repair of the emission control device and systems may be
performed by any non-road engine repair establishment or individual.
