OPERATION
COLD WEATHER OPERATION
If the saw is to used during cold weather, preheat the hy-
draulic fl uid at low engine speed. When using the normally
recommended oils, oil should be at or above 50° F/10° C
(400 ssu/ 82 centistokes) before use.
Damage to the hydraulic system or saw can result from use
with fl uid that is too viscous or thick.
Cutting frozen wood causes the cutters to wear, crack and
break at the back rivet hole unless proper precautions are
taken. To extend chain life when cutting in cold weather:
a. Be sure the oiler is working.
b. Keep the chain tensioned and check often.
c. Keep the cutters properly sharpened. Touch up at least
every hour. Never force a dull chain to cut.
d. Clean out the bar groove and keep the oil hole open.
Turn the bar over to equalize wear on the rails.
e. Always install a new sprocket with a new chain.
