than placing the full workload on the arm and hands.

6.Take precautions to avoid wire, grass and dead, dry, long-stem weeds from wrapping around the head shaft. Such materials can stall the head and cause the clutch to slip, resulting in damage to the clutch system if repeated frequently.

ADJUSTING THE LINE LENGTH

•Your brush cutter is equipped with a semi- auto type nylon line head that allows the operator to advance the line without stopping the engine. When the line becomes short, lightly tap the head on the ground while running the engine at full throttle.

•Each time the head is bumped, the line advances about 25 mm. For better effect, tap the head on bear ground or hard soil. Avoid bumping in thick, tall grass as the engine may stall by overload.

•Make the right and left lines the same length when using the nylon line head.

(Be sure to install the genuine Zenoah debris guard when using the nylon line head.)

•If the lengths of the right and left lines are different, the balance of the nylon line head will be disrupted, resulting in increased vibration and product damage.

The lengths of the right and left lines are significantly different.

-->Make them the same length. The cover is removed.

-->Make sure to install it securely. There is a crack or damage outside.

-->Replace the damaged part.

•If vibration or shaking persists even after repairing, or if you cannot identify the cause of abnormality, con- tact your local authorized Komatsu Zenoah dealer for repair.

•Never continue to operate the unit when vibration or shaking of the drive shaft housing persists.
