MAINTENANCE AND REPAIR INSTRUCTIONS

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 or other qualified service dealer. Call 1-800-4-MY- HOME® for more information.

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.

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.

WARNING: To prevent serious injury, always wear

heavy gloves when handling the tines.

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.
