After every 3-4 times the cutters have been sharpened you need to check the height of the
depth gauges and, if necessary, lower them using the flat file and template supplied optional,
then round off the front corner. (Fig. 22)
WARNING: Proper adjustment of the depth gauge is as important as proper
sharpening of the chain.

Guide bar
The bar should be reversed every 8 working hours to ensure uniform wear. Keep the bar
groove and lubrication hole clean using a bar groove cleaner (optional). (fig. 23) check the bar
rails frequently for wear and, if necessary,
Warning: never mount a new chain on a worn sprocket or self-aligning ring.
Bar wear - turn guide bar frequently at regular intervals (for example, after 8 hours of use), to
ensure even wear on top and bottom of bar.
Oil passages - oil passages on the bar should be cleaned to ensure proper lubrication of the
bar and chain during operation.
Note: the condition of the oil passages can be easily checked. If the
passages are clear, the chain will automatically give off a spray of oil within
seconds of starting the saw. Your saw is equipped with an automatic oiler
system.
11.5
Chain maintenance
Chain tension:
Check the chain tension frequently and adjust as often as necessary to keep the chain snug
on the bar, but loose enough to be pulled around by hand.
Breaking in a new saw chain:
A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during
the break-in period, and the interval between future adjustments will begin to lengthen quickly.
Warning: never have more than 3 links removed from a loop of chain. This
could cause damage to the sprocket.
Chain lubrication:
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with
good quality chain, bar and sprocket oil.
Adequate lubrication of the bar and chain during cutting operations is essential to minimize
friction with the guide bar.
Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will
decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to
excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar
discoloration.
