Troy-Bilt 12215 Arranging Tines For Stony Soil Conditions, Off-Season Storage Procedure

Section 5: Maintenance

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, dis- connect spark plug wire and move wire away from spark plug.

Failure to follow these instructions can result in serious personal injury or property damage.

Arranging Tines

for Stony Soil Conditions

1.Prop the machine forward so it rests on the front of the tubular carrying handle. The work surface should be flat and firm.

2.Remove the ring lock pin (A, Figure 16) from both sides of the unit. Remove both outer tine sections. Mark each section as a left or right side tine and whether it is an inner or outer section.

3.Remove the inner tine sections and

swap their positions (the inner right-side section goes onto the left side of the

To Replace Worn Tine Sections:

The tines are excessively worn if tilling takes much longer than before and soil is not being mixed thoroughly enough.

1.Prop the machine forward so it rests on the front of the tubular carrying handle. The work surface should be flat and firm.

2.Remove the ring lock pin (A, Figure 16) from both sides of the unit. Remove the old tine sections and replace them with new tine sections. Refer to Figure 16 and the tine pattern shown in the Parts List for tine positioning details. Insert the ring lock pins through the rounded side of the tine shafts and snap the ring over the shaft (see DETAIL - Ring Lock Pin, Figure 4, in Section 2).

WARNING

•Never store your equipment when there is fuel mixture in the fuel tank.

•Never place your equipment near any source of sparks or open flame (such as from a hot water heater, a space heater or clothes dryer).

Failure to comply can result in serious personal injury or property damage.

Off-Season Storage Procedure

1.Drain the fuel tank of all of the gaso- line/two-cycle oil mixture. NOTE: Do not use a fuel mixture that is older than one season in order to avoid varnish deposits throughout the fuel system. Dispose of the fuel mixture properly.

2.Start engine and run until fuel mixture is used up. This will prevent poor perfor- mance from stale fuel when your equip- ment is taken out of storage.

NOTE: If “Gasohol” has been used, com- plete above instructions and then put 1/2 pint of gasoline properly mixed with two- cycle oil (see Fuel Mixing Chart) into fuel tank and repeat above instructions.

NOTE: Fuel stabilizer (such as STA-BIL) is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to the fuel mixture in the fuel tank or the fuel storage con- tainer. Always follow the mix ratio instructions on the stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel sta- bilizer.

3.	Let engine cool down after fuel mixture
has been used up. Clean dirt and debris
from engine cooling fins, linkage and
other engine surfaces.
4.	Pull starter handle slowly until resis-

machine, and the inner left-side goes onto the right side of the machine).

4.Reinstall the two outer tine sections on the sides from which they were removed (Figure 18).

5.Insert the ring lock pins through the rounded side of the tine shafts and snap the rings down over the shafts (see DETAIL - Ring Lock Pin, Figure 4, Section 2).

STORAGE

IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, fuel hose, or tank during storage. Also, experience indicates that alcohol- blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

tance is felt due to compression pressure,

then stop. Release starter tension slowly

to prevent engine from reversing due to

compression pressure. This position will

close both the intake and exhaust ports to

prevent corrosion of the piston and

cylinder bore.

5. Remove tines. Clean all soil and debris

from dust covers and tine shaft. Lubri-

cate tine shaft with light oil. Replace

tines.

6. Cover engine and store equipment in a

dry, sheltered location.
