recommended remedies below except remedies that require operation of the unit.
TROUBLESHOOTING TABLE
CHAIN MAINTENANCE
BREAKING IN A NEW SAW CHAIN:
CHAIN LUBRICATION:
BAR WEAR
- Turn guide bar frequently at
regular intervals (for example, after 5
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.
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.
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.
Always make sure the automatic oiler
system is working properly. Keep the oil
tank filled with 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.
