MAINTENANCE AND REPAIR INSTRUCTIONS
Fig. 12a
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. Put the On/Off Stop Control in the STOP (O) position
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. 12a).
3. Clean and oil the shaft.
4. When you are reinstalling tines, lay out the tines and
compare them to those shown in Figure 12b. 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 12b shows the curve in each tine.
5. Using Figures 12a and 12b for reference, slide on the
new tines with the hubs facing outward.
The tines are stamped “A” or “B.” The tine order
should be “B, A, B, A” from left to right when facing
the cultivator from the front.
6. Secure the new tines to the shaft with click pins. It
may be necessary to wash the dirt off the tines and
shaft to help during this entire process.
To prevent serious
injury, always wear
heavy gloves when handling the tines.
WARNING:
MAINTENANCE SCHEDULE
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 Parts & Repair center or other quali-
fied service dealer.
NOTE:
Maintenance, replacement, or repair of the emission
control devices and system may be performed by
any non-road engine repair establishment
or a
Sears parts and repair service center
.
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 Parts & Repair center
or other qualified service dealer. DO NOT attempt to per-
form this process yourself as engine damage may result
from contaminants involved in the cleaning process for
the port.
