ATTENTION
• Always wear gloves when working around the blade assembly.
• Use only original spare parts for this machine.
• Operating the engine without a muffler or with a damaged muffler installed can increase engine
noise enough to cause hearing loss.
REPLACEMENT OF SWORD AND SAW CHAIN
ATTENTION: The saw chain is very sharp, always wear protective gloves when performing any
maintenance on the chain. A dull or worn chain can cause excessive engine speed during cutting,
which can cause severe engine damage. Incorrect chain sharpening increases the potential for
kickback. Failure to replace or repair a damaged chain can cause serious injury.
