Troy-Bilt 12234 Engine Maintenance, Tine Removal Installation, Arranging Tines for Stony Soil

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.

ENGINE MAINTENANCE

WARNING

The temperature of the muffler and adja- cent engine areas may exceed 150oF (65oC). Contact may cause burns. Avoid these areas. Remove the spark plug lead and ground the lead to the engine to prevent accidental starts and fires.

Failure to do this could cause personal injury.

•Maintain the correct engine oil level and change the oil as recommended (more often in dusty conditions).

•Keep the air filter clean. Operating the engine with a dirty, clogged air filter can cause poor performance and damage to the engine. Never operate engine without air filter installed.

•Keep the spark plug clean and properly gapped. Replace every 2 years.

WARNING

Do not tamper with the engine governor screw which is factory-set for the proper engine speed. Overspeeding the engine beyond the factory high speed setting can be dangerous and will void the engine warranty. Authorized service shall be sought if a problem exists.

• The engine cooling fins must be kept

clean to prevent overheating of the

engine.

• If the engine is equipped with a spark

arrester, clean it every year.

• Clean, check or adjust the following

WARNING

Avoid contact with the cutting edges on the tines.

To avoid personal injury when removing or installing tines, wear heavy work gloves. The engine must be off, all moving parts stopped, and the spark plug wire disconnected from the spark plug and moved away from the plug.

ARRANGING TINES FOR NARROW TILLING

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.Flip open the ring (A, Figure 12) on the left side ring lock pin and remove the ring lock pin.

IMPORTANT: The ring lock pin (A, Figure

12)is under spring tension – use care when removing or replacing the ring lock pin.

ARRANGING TINES FOR STONY SOIL

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 12) from both sides of the unit. Remove both outer tine sections. Be sure to 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 ma- chine, and the inner left-side goes onto the right side of the machine).

the Engine Owner’s Manual: fuel tank,

clearance and fuel tubes.

TINE REMOVAL

AND INSTALLATION

The tines wear with use and should be re- placed if tilling takes longer than usual or if the soil does not mix thoroughly. In ad- dition to the standard 10" tilling width tine pattern, the tines can be arranged in a narrow, 41/2" tilling width pattern for smaller areas, and a special pattern for stony soil conditions.

3.Remove the outer tine section (do not remove inner tine section) and mark it as to which side it is from (left or right) and whether it’s an outer or inner tine section.

4.Slide one of the long bushings (B, Figure 13), provided with the unit, onto the shaft. Insert the ring lock pin through the rounded side of the tine shaft and snap the ring down over the shaft (see DETAIL - Ring Lock Pin, Figure 10, in Section 4).

5.Repeat this procedure on the opposite side.

4.Reinstall the two outer tine sections onto the sides from which they were re- moved (Figure 14).

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 10, in Section 4).
