MAINTENANCE SCHEDULE
WARNING:
To prevent serious injury, never perform
maintenance or repairs with unit running. Always service
and repair a cool unit. Disconnect the spark plug wire to
ensure that the unit cannot start.
Perform these required maintenance procedures at the frequency
stated in the table. These procedures should also be a part of any
seasonal tune-up.
NOTE: Some maintenance procedures may require special tools or skills.
If you are unsure about these procedures, take your unit to a
Sears or other qualified service dealer. Call 1-800-4-MY-HOME®
for more information.
NOTE: Maintenance, replacement, or repair of the emission
control devices and system may be performed by a Sears
or other qualified service dealer. Call 1-800-4-MY-HOME®
for more information.
In order to assure peak performance of your engine, inspection of the
engine exhaust port may be necessary after 50 hours of operation. If
you notice lost RPM, poor performance or general lack of acceleration,
this service may be required. If you feel your engine is in need of this
inspection, refer service to a Sears or other qualified service dealer.
Call 1-800-4-MY-HOME® for more information. DO NOT attempt to
perform this process yourself as engine damage may result from
contaminants involved in the cleaning process for the port.

TINE REMOVAL AND REPLACEMENT
All 4 tines should be replaced at the same time because they will
wear evenly through normal use. Work on one side at a time.
1.
Press and hold the Start (I)/ Stop (O) Control in the Stop (O)
position until the unit
comes to a complete stop
and disconnect the spark
plug boot from the plug.
NOTE: It may be necessary
to lay the cultivator
back in a horizontal
position on a flat level
surface with the
handles touching the
ground.
2.
Remove the click pin from
each end of the tine shaft.
Slide the tines off of the
shaft (Fig. 10).
3.
Clean and oil the shaft.
4.
When you are reinstalling
tines, lay out the tines and
compare them to those
shown in Figure 11. Note
specifics about each tine:
its hub, curvature and
lettering ("A" or "B"). This will help make sure that you are
placing the correct tines in the correct order.
NOTE: If you look closely, you can see a slight curvature in the tine
tips. These curves should point toward the front of the
cultivator when the tines are installed. Figure 11 shows the
curve in each tine.
5.
Using Figures 10 and 11 for reference, slide on the new tines
with the hubs facing outward.

this entire process.
AIR FILTER MAINTENANCE
WARNING:
your unit off and allow it to cool before you clean or service it.
The condition of the air filter is
important to the operation of the
unit. A dirty air filter will restrict air
flow and change the air/fuel
mixture. This is often mistaken for
an out of adjustment carburetor.
Check the condition of the air filter
before adjusting the idle speed
screw. Refer to Air Filter
Maintenance.
Removing the Air
Filter/Muffler Cover
1.
Remove the four (4) screws
securing the air filter/
muffler cover (Fig. 12). Use
a flat blade or T20 Torx bit
screwdriver.
