NOTES

When disconnecting power cord, always disconnect power cord from outlet first; then disconnect power cord from switch box on engine. See Figure 37.

When connecting power cord, always connect power cord to switch box on engine first; then into outlet. See Figure 37.

A. Remote Choke

See equipment manufacturer’s instructions and contact an Authorized Tecumseh Servicing Dealer.

B. Changing Oil

To avoid engine damage, it is important to:

Check oil level before each use and every 5 operating hours when engine is warm. See "A. Checking Oil Level" instructions on page 4. Afterward, continue reading instructions below.

Change oil after first 2 operating hours and every 25 operating hours thereafter. Engine should still be warm but NOT hot from recent use.

NOTES

To check oil on engines with an oil fill cap/dipstick, see "I. Oil Fill Cap/Dipstick" instructions on page 5.

To check oil on engines with an oil fill cap/plug, see "II. Oil Fill Cap/Plug" instructions on page 5.

OH195SA, OH195SP, LH358SA, LH195SA, LH195SP specifications

The Tecumseh OH358SA, OH318SA, LH318SA, LH195SP, and LH195SA engines represent a range of high-performance power solutions designed primarily for outdoor equipment including lawn mowers, snow blowers, and other utility applications. These engines are crafted to meet the diverse needs of users, blending efficiency with reliability.

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.
