See Figures 67 - 68.
Clean the cylinder fins and flywheel fins with
compressed air or a brush periodically. Danger-
ous overheating of the engine may occur due to
impurities on the cylinder.
WARNING
Never run the saw without all the parts, including

in place.
Because parts can fracture and pose a danger
of thrown objects, leave repairs of the flywheel

be blocked with carbon deposits. These deposits
may need to be removed to restore performance.
