MAINTENANCE & REPAIR INSTRUCTIONS

AIR FILTER MAINTENANCE

WARNING:

To avoid serious personal injury, always turn the unit off

and allow it to cool before cleaning or maintaining it.

Failure to maintain the air filter properly can result in poor performance or can

cause permanent damage to the engine.

Open the air filter cover by

pressing the lock tab in and

pulling out on the air filter

cover (Fig. 26).

Remove the air filter (Fig. 26).

Wash the filter in detergent

and water. Rinse the filter

thoroughly and allow it to dry.

Apply enough clean SAE 30

motor oil to lightly coat the

filter.

Squeeze the filter to spread

and remove excess oil.

Replace the air filter into the base plate (Fig. 26).

NOTE:

Operating the unit without the air filter WILL VOID the warranty.

Reinstall the air filter cover. Position the two small tabs on the air filter

cover into the two slots in the base plate and press the air filter cover

down, making sure to align the lock tab with the lock tab slot, until it

snaps into place (Fig. 26).

IDLE SPEED ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw is

between the air filter cover and the engine starter housing (Fig. 27).

NOTE:

Careless adjustments can seriously damage the unit. Aside from

idle speed, only a Sears or other qualified service dealer should

make carburetor adjustments.

If, after checking the fuel and cleaning the air filter, the engine still will not

idle, adjust the idle speed screw as follows:

Start the engine and let it run

at a high idle for a minute to

warm up. Refer to

Starting/Stopping

Instructions.

Release the throttle trigger and

let the engine idle. If the engine

stops, insert a small phillips

screwdriver in between the Air

Filter Cover and the Engine

Cover (Fig. 27). Turn the idle

speed screw in, clockwise, 1/8

of a turn at a time (as needed)

until the engine idles smoothly.

NOTE:

The cutting attachment should not rotate when the engine idles.

If the cutting attachment rotates when the engine idles, turn the idle

speed screw counterclockwise 1/8 of a turn at a time (as needed), to

reduce idle speed.

Checking the fuel, cleaning the air filter, and adjusting the idle speed should

solve most engine problems. If not and any of the following are true have the

unit serviced by a Sears or other qualified service dealer:

• the engine will not idle

• the engine hesitates or stalls on acceleration

• there is a loss of engine power

REPLACING THE SPARK PLUG

Use a Champion RDJ7J or a

replacement part #753-06193

spark plug (or equivalent).

Stop the engine and allow it

to cool. Grasp the plug boot

firmly and pull it from the

spark plug.

Clean around the spark plug.

Remove the spark plug from

the cylinder head by turning

a 5/8-inch socket

counterclockwise.

WARNING:

Do not sand blast, scrape or clean spark plug

electrodes. Grit in the engine could damage the cylinder.

MAINTENANCE & REPAIR INSTRUCTIONS

Replace a cracked, fouled or dirty spark plug. Set the air gap at 0.025

in. (0.635 mm) using a feeler gauge (Fig. 28).

Install a correctly-gapped spark plug in the cylinder head. Tighten by

turning the 5/8-inch socket clockwise until snug. If using a torque

wrench, torque to:

110-120 in.•lb. (12.3-13.5 N•m). Do not over-tighten.

Reattach the plug boot.

CLEANING

Use a small brush to clean off the outside of the unit. Do not use strong

Tab

detergents. Household cleaners that contain aromatic oils such as pine and

lemon, and solvents such as kerosene, can damage plastic housing or handle.

Wipe off any moisture with a soft cloth.

STORAGE

• Never store a fueled unit where fumes may reach an open flame or spark.

Air

Filter

• Allow the engine to cool before storing.

• Store the unit locked up to prevent unauthorized use or damage.

• Store the unit in a dry, well-ventilated area.

• Store the unit out of the reach of children.

LONG TERM STORAGE

If planning on storing the unit for an extended time, use the following storage

procedure:

Remove the fuel cap, tip the unit and drain the fuel into an approved

container.

NOTE:

Do not use gasoline that has been stored for more than 30 days.

Dispose of old gasoline in accordance with federal, state and local

regulations.

Start the engine and allow it to run until it stalls. This ensures that all

fuel has been drained from the carburetor.

Allow the engine to cool. Remove the spark plug and put 5 drops of

high quality motor oil into the cylinder. Pull the starter rope slowly to

distribute the oil. Reinstall the spark plug.

NOTE:

Remove the spark plug and drain all of the oil from the cylinder before

attempting to start the trimmer after storage.

Thoroughly clean the unit and inspect it for any loose or damaged

parts. Repair or replace damaged parts and tighten loose screws, nuts

or bolts. The unit is ready for storage.
