MAINTENANCE

Checking the Engine's Cooling Air Intake

Check that the engine’s cooling air intake is free from leaves, grass, and dirt.

If the cooling air intake is clogged, engine cooling deteriorates, which can lead to engine damage.

Checking and Adjusting

the Throttle and Choke Cable

Check that the engine responds to throttle increases and that a good engine speed is attained at full throttle.

If doubts arise, contact the Husqvarna service workshop.

If adjustments are necessary, they can be made as follows for the cable:

1.Loosen the clamping screw for the cable’s outer casing.

2.Check that the throttle cable is mounted in the correct hole in the lever.

3.Set the throttle lever at full throttle with no choke.

4.Align the hole in the speed control lever with the hole in the base plate by moving the lever. Insert a 6 mm dia pin (or a screw) through the two holes.

5.Pull up the outer housing of the throttle cable until the inner wire has almost no slack and tighten the clamping screw.

6.Remove the 6 mm pin.

7.Make sure that the carburetor choke valve is closed completely when the throttle lever is moved to choke position.

8.Check engine idle speed.

Check and clean the cooling air intake
