Adjusting the idle Speed

 

wARNiNG

The saw chain may spin during idle speed adjustments. 
Wear protective gloves and clothing and observe all safety 
instructions to prevent serious personal injury.

If, after checking the fuel and cleaning the air filter, the engine still 
will not idle, adjust the idle speed screw as follows:

1.  Start the engine. Refer to 

Starting and Stopping

.

2.  Release the throttle control and let the engine idle.

2a. If the engine stops, use a small Phillips or flat-head 

screwdriver to turn the idle speed screw clockwise, 1/8 
of a turn at a time (as needed) until the engine idles 
smoothly (Fig. 43).

2b. If the engine idles too quickly, turn the idle speed screw 

counterclockwise, 1/8 of a turn at a time (as needed) to 
reduce the idle speed (Fig. 43).

 

NOTiCE

The saw chain should not spin when the engine idles. If it 
does, reduce the idle speed until the saw chain stops moving.

Checking the fuel, cleaning the air filter, and adjusting the idle 
speed should solve most engine problems. If not, and any of the 
following conditions are true, take the chainsaw to a Champion or 
other qualified service dealer:

 

–

The engine will not idle.

 

–

The engine hesitates or stalls on acceleration.

 

–

There is a loss of engine power.

Maintaining the Spark Plug

1.  Stop the engine and allow it to cool.

2.  Turn the knob on the air filter cover counterclockwise to 

loosen the air filter cover (Fig. 41).

3.  Remove the air filter cover (Fig. 41).

4.  Grasp the spark plug boot firmly and pull it from the spark 

plug (Fig. 44).

5.  Clean around the spark plug. Remove the spark plug from the 

cylinder head with the multi-purpose tool or a 5/8-inch socket 
wrench, turning counterclockwise.

 

wARNiNG

Do not sand blast, scrape or clean spark plug electrodes. Grit 
in the engine could damage the cylinder.

6.  Inspect the spark plug. If the spark plug is cracked, fouled 

or dirty, replace it with a Champion RCJ7Y or Bosch L8RTF 
Spark Plug

7.  Use a feeler gauge to set the air gap at 0.026 in. (0.65 mm)

(Fig. 45).

8.  Install the spark plug in the cylinder head. Tighten the spark 

plug with the multi-purpose tool or a 5/8-inch socket wrench, 
turning it clockwise until snug.

 

NOTiCE

If using a torque wrench, torque to: 110-120 in.•lb. 
(12.4-13.5 N•m). Do not over tighten.

9.  Reattach the spark plug boot.

10. Place the air filter cover back onto the chainsaw. Insert 

the tab on the air filter cover into the slot on the chain saw 
housing (Fig. 41).
