TUNE-UP KIT

COOLING SYSTEMS CLEANING

Level 2.

Tools required: Cross Head Screwdriver, 3 mm Hexagon wrench,

Pointed Wood Stick, Cleaning Brush, 25-50 mm

(1-2 in.) medium bristle paint brush.

Parts Required: None.

IMPORTANT

To maintain proper engine operating temperatures, cooling air must

pass freely through the cylinder fin area. This flow of air carries

combustion heat away from the engine.

Overheating and engine seizure can occur when:

• Air intakes are blocked, preventing cooling air from reaching the

cylinder.

• Dust and grass build up on the outside of the cylinder. This build up

insulates the engine and prevents the heat from leaving.

Removal of cooling passage blockages or cleaning of cooling fins is

considered “Normal Maintenance”. Any failure attributed to lack of

maintenance is not warranted.

1. Remove spark plug lead and throttle linkage end from the carbure-

tor swivel.

2. Remove the four screws that retain the cover. Two at the top of the

Recoil Starter, two on either side of the front. Lift the cover from the

engine and lay to the front of the trimmer.

NOTE

The throttle linkage remains assembled to the cover and the spark

plug lead and grommet remain installed.
