■ 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

28), 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. 

3. Place the RedMax Sweeper main gear flat. Refill the

gearcase with Mobil SHC 634 Synthetic Gear Oil to
the top of the main gear (60ml – 1.80zs), as shown.
DO NOT OVERFILL! (MA1)

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.
