ENGINE OIL SERVICE
Check the engine oil level before starting
the engine each day and check it after
each 5 hours of continuous operation.
Running the engine when it is low on oil
will quickly ruin the engine.
It is recommended that you change the
motor oil after every 10 hours of opera­
tion and even sooner when operating in
extremely dirty or dusty conditions. Refer
to the separate Engine Owner’s Manual
for detailed service instructions.
A. To Check the Engine Oil Level:
1. Move the tiller to a level area and shut
off the engine.
2. Level the engine by moving the Depth
Regulator Lever up or down as needed.
3. Clean the area around the oil dipstick
or oil fill tube to prevent dirt from falling
into the crankcase.
4. On engines with an oil fill tube, remove
the filler cap, add oil (if required) until it
reaches the top of the tube and reinstall
the filler cap.
5. On engines with a dipstick, remove it,
wipe it clean, and reinstall it finger-tight.
Remove the dipstick and check the
reading. Add oil (if required) to bring the
level to the FULL mark. Do not overfill.
B. To Change the Engine Oil:
Change the engine oil as instructed in the
separate Engine Owner’s Manual.
AIR CLEANER SERVICE
The engine air cleaner filters dirt and dust
out of the air before it enters the carbure­
tor. Operating the engine with a dirty,
clogged air filter can cause poor perfor­
mance and damage to the engine. Never
operate the engine without the air cleaner
installed. Inspect and service the air
cleaner more often if operating in very
dusty or dirty conditions.
Service the air cleaner as instructed in the
separate Engine Owner’s Manual.
SPARK PLUG SERVICE
Inspect and clean or replace the spark
plug after every 100 operating hours or
annually. Clean the plug and set the gap
as described in the separate Engine
Owner’s Manual.
In some areas, local law requires using
resistor spark plugs to suppress ignition
signals. If the engine was originally
equipped with a resistor spark plug, use
the same type for replacement.
SPARK ARRESTER SCREEN
SERVICE
If the engine muffler is equipped with a
spark arrester screen, remove and clean it
according to the time intervals and
instructions In the separate Engine
Owner’s Manual.
ENGINE CLEANING
The engine must be kept clean to assure
smooth operation and to prevent damage
from overheating. Refer to the separate
Engine Owner’s Manual for specific repair
and cleaning instructions. All inspections
and services must be done with the
engine shut off and cool to the touch.
CARBURETOR/GOVERNOR
CONTROL AOJUSTMENTS
A WARNING
Operators shall not tamper with the
engine
governor settings on the
machine; the governor controis the
maximum
safe operating speed to
protect the engine and aii moving parts
from damage caused by overspeed.
Authorized service shaii be sought if a
probiem exists.
The carburetor was adjusted at the
factory for best operating speed. Refer to
the separate Engine Owner’s Manual for
any adjustment information or see your
authorized engine service dealer.
The governor controls the maximum safe
operating speed and protects the engine
and all moving parts from damage caused
by overspeeding. Do not tamper with the
engine governor settings. Seek autho­
rized service if a problem exists.
THROTTLE CONTROL AOJUSTMENT
If the engine does not respond to various
throttle lever settings, refer to the sepa­
rate Engine Owner’s Manual for service
information or contact your local autho­
rized engine service dealer.
