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 chain saw 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.
CAUTION
Remember, the anti-kickback protection shall be set in the clutch cover side to prevent kickback when
making horizontal cuts level with the ground.
• 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.

Anti-Kickback Protection
• Before operating the chain saw double check the
anti-kickback protection screws are duly tightened.
• The anti-kickback protection screws have a special
hardening. If it is not tight replace it altogether with the
guard before operating the chain saw. Do not try to use
any other or different screw type.
• To set correctly the anti-kickback protection fit together
the guard protrusion into the corresponding hole in the
bar (B).
• Tighten the screw with your fingers and then, use a 5/16"
key to finish tightening exactly 3/4 turn (C).
