■ GEAR CASE
• The reduction gears are lubricated by
multipurpose, lithium-based grease in
the gear case. At every 20 hours of
use, supply the gear case with new
grease.
• Remove the cutter holders before
installing new grease to arrange for old
grease to exit.
• When removing and installing the cutter
holder(a), use care not to allow any dirt
and dust entering in to the gear case.
NOTE
(RMS-EX only)
■ 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.
1. Remove the drum and axle assemblies
(see page 12), and then remove the
four end cap bolts and the end cap (the
gearcase need not be removed from
the RedMax Sweeper).
2. Allow all used gearcase oil to drain into
a small container.
BURN DANGER! The gearcase and oil
will be extremely hot after use!

4. Apply a continuous bead of loctite ultra
grey around the pilot diameter of the
end cap. Install the end cap, and then
install and firmly tighten the four end
cap bolts.
5. Install the drum and axle assemblies,
and then reconnect the spark plug wire.
• Use only Mobil SHC 634 Synthetic
Gear Oil.
• Do not mix other oils ar additives with
the RedMax Sweeper Gearcase Oil.
• Do not disturb the sealed end plug or
bolt on the gearcase (leakage may
occur).
• Do not use the RedMax Sweeper if oil
is leaking from the gearcase. Return
the machine to the dealer for repairs.
Make sure that the engine has stopped
and is cool before performing any
service to the machine. Contact with
moving sweeping head or hot muffler
may result in a personal injury.
