Replacing/Changing Chain and Guide Bar
Replace chain when cutters are too worn to sharpen or when chain stops.
Only use replacement chain noted in this manual.
Inspect guide bar before replacing chain.
A worn or damaged guide bar is unsafe and will damage chain. It will also make cutting harder.
Fit the chain and guide bar as described in “Tensioning Chain”. The circular groove of the
guide bar will wear particularly on the lower edge with time. When replacing the chain turn the
chain bar 180° to allow even wear, thus extending chain bar life.
Check drive sprocket. If it is worn out or damaged due to strain, have it exchanged by an
authorized service dealer.
If the chain bar is worn out or damaged, take the chain tensioning catch off the bar by
