IMPORTANT!
MAINTENANCE, REPLACEMENT
OR REPAIR OF EMISSION CONTROL
DEVICES AND SYSTEMS MAY BE PER-
FORMED BY ANY REPAIR ESTABLISH-
MENT OR INDIVIDUAL; HOWEVER,
WARRANTY REPAIRS MUST BE PER-
FORMED BY A DEALER OR SERVICE
CENTER AUTHORIZED BY Swisher INC.
THE USE OF PARTS THAT ARE NOT
EQUIVALENT IN PERFORMANCE AND
DURABILITY TO AUTHORIZED PARTS
MAY IMPAIR THE EFFECTIVENESS OF
THE EMISSION CONTROL SYSTEM
AND MAY HAVE A BEARING ON THE
OUTCOME OF A WARRANTY CLAIM.
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.
Muffler
This unit must never be operated with
a faulty or missing spark arrester or
muffler. Make sure the muffler is well
secured and in good condition. A worn or
damaged muffler is a fire hazard and may
also cause hearing loss.
NOTE:
Using non-standard replacement parts
could invalidate your Swisher warranty.
Daily maintenance
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.
■
Clean any debris or dirt from the cut-
ting attachment.
WARNING!
Before performing any main-
tenance, 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.
Spark Plug
Keep the spark plug and wire connections
tight and clean.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
Air Filter
The E4 engine that powers your Swisher
model is a hybrid 4-stroke engine. As a
hybrid, the engine is lubricated by oil
mixed with the gasoline and air from the
carburetor that moves through and around
the internal parts of the engine in a similar
way that a 2-stroke engine is lubricated.
Without the heavy duty 2-stage air filter
equipped on all E4 engines, dust and
dirt could also move through the engine,
decreasing engine life, increasing valve
wear and the need for more frequent valve
adjustments. To keep your E4 engine
strong and reliable, Swisher recommends
that you check and service the air filter
as instructed in the 10-Hour Maintenance
section that follows.
■
Check the entire unit for leaking fuel
or grease.
■
Check for loose or missing screws or
components. Make sure the cutter
attachment is securely fastened.
■
Make sure nuts, bolts, and screws
(except carburetor idle speed adjusting
screws) are tight.
Blades
Keep blades sharp and check blade
condition frequently. If a blade's per-
formance changes suddenly, stop the
engine and check the blade for cracks or
other damage. Replace a damaged blade
IMMEDIATELY!
WARNING!
■
Never repair a damaged blade by
welding, straightening, or by modi-
fying its shape. An altered blade
may break during operation, result-
ing in serious personal injury.
■
DO NOT use 2-tooth or NON-
Swisher approved 4-tooth cutting
blades on Swisher trimmers or
brushcutters.
■
Blades are not interchangeable
between Swisher edgers and trim-
mer/brushcutter models. Operat-
ing any unit with a blade or attach-
ment not approved for that unit
can be hazardous and may cause
serious injury.
■
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 areas can lead to engine
overheating, fire, or premature wear.
