Section 5:  Maintenance

WARNING  

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

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.

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 ADJUSTMENTS

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 ADJUSTMENT

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.

WHEEL GEAR CABLE ADJUSTMENT

When the Wheel Gear Lever is in DISEN-
GAGE, the wheels will roll freely (free-
wheel).  The wheels should not roll freely
when the lever is in ENGAGE.  If the
wheels roll freely when the Wheel Gear
Lever is in ENGAGE, the wheel gear cable
needs to be adjusted as described below.

1. With the engine shut off and the spark
plug wire disconnected, put the Wheel
Gear Lever in ENGAGE.

2. Loosen the top adjustment nut (A,
Figure 5-5) on the wheel gear cable
bracket that is located on the left side rear
of the transmission.

3. Push the wheel gear cable (B) down
and roll the tiller slightly forward or back-
ward until the eccentric lever (C) engages
(locks) the wheels.  Hold the cable in that
position and tighten the top (A) and
bottom (D) adjustment nuts.

4. Move the Wheel Gear Lever to ENGAGE
and DISENGAGE several times to check
the adjustment.  The wheels should not
roll when the lever is in ENGAGE,  but
they should roll when the lever is in DIS-
ENGAGE.  Readjust the cable as required.

OFF SEASON STORAGE

When the tiller won’t be used for
extended periods, prepare it for storage
as follows:

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 engine storage instructions found in
the separate Engine Owner’s Manual.
NOTE: 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.).

WARNING

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.
