Maintenance
WARNING!
Before performing any mainte-
nance, repair, or cleaning work on the
unit, make sure the engine and cutting
attachment are completely stopped.
Disconnect the spark plug wire before
performing service or maintenance.
WARNING!
Non-standard accessories,
cutting attachment, or replacement
parts may not operate properly with
your unit and may cause damage
and lead to personal injury.
Prior to each work day, perform the
following:
Remove all dirt and debris from the
engine, check the cooling fins and
air cleaner for clogging, and clean as
necessary.
Carefully remove any accumulations
of dirt or debris from the muffler and
fuel tank. Check cooling air intake
area at base of crankcase. Remove
all debris. Dirt build-up in these ar-
eas can lead to engine overheating,
fire, or premature wear.

IMPORTANT!
For detailed maintenance information
about your unit, consult the owner's
manual that was provided with it. If it has
been lost or misplaced, contact Swisher
for a replacement.

Gearcase Lubrication
The gearcase should be filled with 60 cc
(2.0 fl.oz.) of Mobil SHC634 Synthetic Gear
Oil. A maximum of 75-80 cc can be used,
but never to exceed 80 cc. Operation with
excessive oil level will result in high operat-
ing temperatures.
Do not overfill!
Replacing the gearcase oil
Turn the gearcase to the LH side and
and allow all used gearcase oil to drain
into a small container.
