! WARNING

II. Oil Cylinder Bore

When lubricating cylinder bore, fuel may spray from spark plug hole. To

prevent serious injury from fuel fires, follow these instructions:

1.Carefully disconnect spark plug wire and keep it away from spark plug. See Figures 53 and 54.

Keep the disconnected spark plug wire securely away from metal parts where arcing could occur.

Carefully attach the spark plug wire to the grounding post, if provided.

Disconnect battery at negative terminal first, if engine is equipped with a D.C. electric starter.

Turn all engine switches to “OFF” position.

Remove ignition key, if provided.

2.Remove spark plug.

3.Squirt 1oz. (30ml) of clean engine oil into spark plug hole.

4.Cover spark plug hole with rag to prevent fuel from spraying from spark plug hole when starter rope is pulled.

NOTES

For engines equipped with recoil starters proceed to Step 5.

For engines equipped with electric starters proceed to Step 6.

5.Grasp starter cord handle:

a.Pull starter cord handle out slowly using a full arm stroke.

b.Repeat once. (This will distribute oil throughout the cylinder to prevent corrosion during storage.)

c.Proceed to Step 7.

6.Push starter button or turn ignition switch key to “START” position. Immediately release starter button or turn ignition switch key to “OFF” position. (This will dis- tribute oil throughout the cylinder to prevent corrosion during storage.)

7.Remove rag from spark plug hole.

8.Install spark plug.

9.Carefully disconnect spark plug wire from grounding post, if provided. See Figure 53.

10.Connect spark plug wire to spark plug. See Figure 54.

III. Oil

Change oil if NOT changed within the last 3 months. See "B. Changing Oil" instructions on page 17.

IV. Battery

See equipment manufacturer’s instructions for proper battery storage, if present.

The OH358SA is a standout model featuring a powerful overhead valve (OHV) design that enhances performance while ensuring fuel efficiency. This engine is known for its air-cooled, single-cylinder configuration that delivers robust power. With a displacement of 358cc, it is capable of producing substantial torque, making it excellent for larger mowers and commercial-grade applications.

On the other hand, the OH318SA engine is a versatile alternative equipped with similar principles of efficiency and power. With a displacement of 318cc, it is designed for medium-duty equipment, providing sufficient grunt for residential mowing tasks and light commercial usage. Its compact size and lightweight design contribute to improved maneuverability, which is advantageous in tight spaces.

The LH318SA takes the durability of the OH318SA a step further by integrating a heavy-duty crankshaft and reinforced components. This model is particularly suited for harsh working conditions, combining a robust build with an innovative air filtration system that prolongs engine life by maintaining cleanliness in critical areas.

The LH195SP and LH195SA models gear towards smaller applications, offering a balance between performance and weight. Both engines feature a 195cc displacement, making them ideal choices for lightweight equipment. The LH195SP is particularly designed with self-propelling mechanisms in mind, enabling effortless operation of lawn mowers and similar devices.

In terms of technologies, all these models leverage Tecumseh’s commitment to engineering excellence, incorporating sound dampening features for reduced noise levels and enhanced user comfort. They are also equipped with easy-start technology, ensuring that even novice users can get going without cumbersome procedures.

The combination of high-quality materials, ergonomic designs, and technological innovations ensures that Tecumseh engines remain reliable under various loads and operating conditions. These characteristics make them a preferred choice among professionals and homeowners alike, ensuring reliability and efficiency in outdoor tasks. Whether tackling large fields with the OH358SA or maintaining small lawns with the LH195SA, there’s a Tecumseh engine designed to meet every user's demands.
