3.  Clean around the oil dipstick or oil fill 
tube (whichever applies) to prevent dirt 
from falling into the crankcase.  
4.  On engines with an oil fill tube, remove 
the fill cap and add oil (if required) until it 
reaches the top of the fill tube.  Reinstall 
the fill cap. 
5.   On engines with a dipstick, remove it 
and wipe it clean.  Reinsert the dipstick, 
tighten it securely, and remove it.  Add oil 
as needed to bring the level up to the FULL 
mark.  Wipe dipstick clean each time oil 
level is checked.  Do not overfill.  Tighten 
dipstick securely.

Change the engine oil as instructed in the 
Engine Owner’s Manual.

Inspect and clean or replace the spark plug 
after every 100 operating hours or annual-
ly.  Refer to the Engine Owner’s Manual for 
spark plug service instructions.  

In some areas, local law requires using re-
sistor spark plugs to suppress ignition sig-
nals.  If the engine was originally equipped 
with a resistor spark plug, use the same 
type for replacement.

If the engine muffler is equipped with a 
spark arrester screen, remove and clean it 
according to the service intervals and in-
structions in the Engine Owner’s Manual. 

If the engine does not respond to various 
throttle lever settings, refer to the Engine 
Owner’s Manual for service information or 
contact your local authorized engine deal-
er.

Operators 

shall not tamper with the engine 
governor settings on the 
machine; the governor controls 
the maximum safe operating 
speed to protect the engine and 
all moving parts from damage 
caused by overspeed.  
Authorized service shall be 
sought if a problem exists.

The carburetor was adjusted at the factory 
for best operating speed.  Refer to the En-
gine Owner’s Manual for any adjustment 
information or see your authorized engine 
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.  

When the tiller won’t be used for an ex-
tended period, prepare it for storage as fol-
lows:

1.  Clean the tiller and engine.

2.  Do routine tiller lubrication and check 
for loose parts and hardware.

3.  Protect the engine and perform recom-
mended engine maintenance by following 
the storage instructions found in the En-
gine Owner’s Manual.  Be sure to protect 
the fuel lines, carburetor and fuel tank 
from gum deposits by removing fuel or by 
treating fuel with a fuel stabilizer (follow 
engine manufacturer’s recommendations). 

4. Store unit in a clean, dry area. 

5.  Never store the tiller with fuel in the fuel 
tank in an enclosed area where gas fumes 
could reach an open flame or spark, or 
where ignition sources are present (space 
heaters, hot water heaters, furnaces, etc.).

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all 

moving parts to come to a complete stop, disconnect spark plug wire and move wire away from 
spark plug. Failure to follow these instructions can result in serious personal injury or property 
damage.
