■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.
