Chain Depth Gauge
• The chain is built with drive sprockets (depth gauge)
placed in front of each sprocket. These prevent the
sprockets enter too deep in the wood and get stuck
generating kickback.
• Depth gauge shall be checked each time the chain is
honed to verify the sprockets have the right height with
regards to the drive sprockets upper plate.
• The difference in height of the depth gauge and the
sprockets shall always be 0.025"
• When due to normal wear and / or honing the chain,
the difference is lower, use a depth gauging instrument
and a flat file to make even and verify the difference to
0,025"
• File only the depth gauge. File in the same direction you
filed the adjacent sprocket. Use care and do not touch the
cutting tip.
• After making even the difference in all the drive, file
each sprocket one by one to give them back the original
shape making the front round (A).
Chain Bar Maintenance
• The chain bar shall be cleaned at the end of the cutting
journey. Also, checked thoroughly to identify wear or
possible damage.
• Apparition of small grooves and lumps in the bar rails
are caused by the chainsaw normal use. Make them
smooth with a file as soon as identified.
• Clean all debris from the lubrication orifice and the
cutting chain slot.
• After a week's work reverse the chain bar to distribute
the normal wear and make its useful life longer.
• After a week's work lubricate the chain bar if it has a
cogwheel in the nose. Use a grease syringe to apply
lubricant in the lubrication orifice.
• If the rail shows wear do not leave the chain
resting on its side, do not allow it to be
widened or that the chain bar is
bent. Replace the complete bar
with a new one.
