When the diameter of the wood is large enough for a
wedge to be inserted in
thecut behind the saw chain, usea
wedge to hold the cut open when there is a danger of pin-
ching the saw blade. When felling large trees, wedges
should also be used to control the fall. Never use hard
metal wedges which could damage the saw chain. Note:
Remove
SAFEoToTIP before using wedge.
Clear your working area of all materials likely to trip you,
snag the saw, catch fire from the hot exhaust, or block
your safe retreat from a falling tree.
Before cutting limbs or felling trees, inspect
thearea to be
sure the wood will not strike buried pipelines or damage
property.
Always use a muffler on your saw and keep it in good re-
pair. A faulty muffler (or open exhaust) can cause hearing
damage and is also a fire hazard. Be sure to use a spark
arrestor on your muffler under dry woods conditions, and
always when required by the law or local authorities. In
some states, a spark arrestor is required by law and it is
the operator's legal responsibility to see that it is in good
condition at all times. Check the muffler and spark ar-
restor at regular intervals. Careful! Never touch a hot
muffler.

A SPARK ARRESTOR IS ONLY ABOUT
90%
EFFICIENT IN PREVENTING FIRES.
LOCAL AUTHORITIES MAY CLOSE THE
FOREST DURING EXTREMELY DRY PERIODS.
Inspect your saw every day before use. Keep the fuel cap,
oil cap and air filter cover on tightly. Check condition of
the fuel line, spark plug and spark plug wire. DO NOT OP-
ERATE IF THE ENGINE BACKFIRES OR THE SAW
LEAKS FUEL. Have your saw serviced by an authorized
serviceman. Be sure to keep your saw chain in proper con-
dition on the saw. Remember that a dull or loose chain
snags more easily than a sharp, snug chain. Touch
upthe
chain after two hours of steady cutting and sharpen it
thoroughly after
8-10
hours of use. (See Chain and Bar
Maintenance in Section
6.)
If chain is damaged by abra-
sives or hits a stone or nail, put on a spare chain immedi-
ately and have the damaged chain repaired and sharpened.
If there is anything wrong with
thesaw have itfixed before
further operation. The idle speed adjustment should be
maintained so that the chain stops moving after the en-
gine is brought back to idle. Adjust the idle speed when-
ever necessary (see Section
6).
NOTE
Do not disassemble the rotor (flywheel). Special tech-
niques are required (on a dealer level) for safe removal
and installation of the rotor. Never start up your engine
unless the guide bar and chain are installed. Without the
guide bar in place, the clutch can fly off or explode.
UNUSUALLY HAZARDOUS
CONDITIONS
Do not fell trees or go underneath them during periods of
high wind or heavy precipitation. Take nochancesduring
periods of extreme hazard. You can wait to do your cutting
after the hazard has ended.
Do not use saws to cut down trees having an extreme lean
or large trees that have rotten limbs, loose bark, or hollow
trunks. Have these trees pushed or dragged down with
power equipment. Then you can cut them up.
Work only when visibility and
light areadequate for you to
see perfectly what you are doing.
