B. Removing Debris from Engine Before each use, remove grass clippings, dirt and debris from the following areas: • Levers and Linkage • Cooling Fins • Air Intake Screen • Guards Removing debris will insure adequate cooling, correct engine speed and reduce the risk of fire. See Figure 30. C. Spark Plug Check spark plug yearly or every 100 operating hours. 1. Clean area around spark plug. 2. Remove and inspect spark plug. 3. Replace spark plug if porcelain is cracked or if electrodes are: • Pitted • Burned • Fouled with Deposits 4. Check electrode gap with wire feeler gauge and set gap to-.030 in. (0.76 mm) if necessary. See Figure 31. 5. Install spark plug and tighten securely. NOTE A resistor spark plug must be used for replacement. Contact your Authorized TecumsehPower Servicing Dealer for a genuine replacement Resistor Spark Plug. D. Cleaning/Replacing Air Cleaner Your engine has an air cleaner which helps prevent premature engine wear and failure. NEVER run engine without complete air cleaner installed on engine. Your air cleaner periodically needs to be cleaned or replaced. To do this, you first need to determine the type of air cleaner on your engine. Your engine will be equipped with one of the following air cleaners; Type A or B. Follow instructions for the air cleaner type that resembles your model. See Figures 32 and 33 on page 14. Afterward, continue reading instructions below. NOTE Contact your Authorized TecumsehPower Servicing Dealer for a genuine replacement Air Cleaner. I. Servicing Foam Filters Clean foam pre-filter every 3 months or every 25 operating hours. Clean daily if used in extremely dusty conditions. After removing the pre-filter, follow these cleaning instructions below: 1. Wash in warm water and detergent solution then press (DO NOT twist) until all dirt is removed. 2.

Removing Debris from Engine

Before each use, remove grass clippings, dirt and debris

from the following areas:

•

Levers and Linkage

•

Cooling Fins

•

Air Intake Screen

• Guards

Removing debris will insure adequate cooling, correct

engine speed and reduce the risk of fire. See Figure 30.

Spark Plug

Check spark plug yearly or every 100 operating hours.

Clean area around spark plug.

Remove and inspect spark plug.

Replace spark plug if porcelain is cracked or if

electrodes are:

• Pitted

• Burned

•

Fouled with Deposits

Check electrode gap with wire feeler gauge and set

gap to—.030 in. (0.76 mm) if necessary. See Figure 31.

Install spark plug and tighten securely.

NOTE

A resistor spark plug must be used for replacement. Contact

your Authorized TecumsehPower Servicing Dealer for a

genuine replacement Resistor Spark Plug.

Cleaning/Replacing Air Cleaner

Your engine has an air cleaner which helps prevent

premature engine wear and failure. NEVER run engine

without complete air cleaner installed on engine. Your air

cleaner periodically needs to be cleaned or replaced. To do

this, you first need to determine the type of air cleaner on

your engine. Your engine will be equipped with one of the

following air cleaners; Type A or B. Follow instructions for

the air cleaner type that resembles your model. See

Figures 32 and 33 on page 14. Afterward, continue reading

instructions below.

NOTE

Contact your Authorized TecumsehPower Servicing Dealer

for a genuine replacement Air Cleaner.

Servicing Foam Filters

Clean foam pre-filter every 3 months or every 25 operating

hours. Clean daily if used in extremely dusty conditions.

After removing the pre-filter, follow these cleaning

instructions below:

Wash in warm water and detergent solution then press

(DO NOT twist) until all dirt is removed.

Rinse thoroughly until water is clear.

Wrap in a clean cloth and press (DO NOT twist) until

completely dry.

NOTE

DO NOT oil foam pre-filter.

Replace foam pre-filter onto paper filter.

II.

Servicing Paper Filters

Paper filters cannot be cleaned and must be replaced once

a year or every 100 operating hours; more often if used in

extremely dusty conditions. Replacement filters are

available at a Authorized TecumsehPower Servicing

Dealer. Follow the instructions next to the drawing of your

air cleaner to remove and replace it.

NOTE

DO NOT put oil on or clean a paper filter.
