SDo not operate a chain saw that is dam- aged, improperly adjusted, or not com- pletely and securely assembled. Always replace bar, chain, hand guard, or chain
brake immediately if it becomes damaged, broken or is otherwise removed.
SWith the engine stopped, hand carry the chain saw with the muffler away from your body, and the guide bar and chain to the rear, preferably covered with a scabbard.
MAINTAIN YOUR SAW IN GOOD WORKING ORDER
SHave all chain saw service performed by a qualified service dealer with the exception of the items listed in the maintenance section of this manual. For example, if improper tools are used to remove or hold the flywheel when servicing the clutch, structural damage
to the flywheel can occur and cause the fly- wheel to burst.
SMake certain the saw chain stops moving when the throttle trigger is released. For
correction, refer to CARBURETOR AD-
JUSTMENTS.
SNever modify your saw in any way. Use only attachments supplied or specifically recommended by the manufacturer.
SKeep the handles dry, clean, and free of oil
or fuel mixture.
SKeep fuel and oil caps, screws, and fas- teners securely tightened.
SUse only McCullochR accessories and re- placement parts as recommended.
HANDLE FUEL WITH CAUTION
SDo not smoke while handling fuel or while
operating the saw.
SEliminate all sources of sparks or flame in the areas where fuel is mixed or poured. There should be no smoking, open flames, or work that could cause sparks. Allow en-
gine to cool before refueling.
SMix and pour fuel in an outdoor area on bare ground; store fuel in a cool, dry, well venti- lated place; and use an approved, marked container for all fuel purposes. Wipe up all
fuel spills before starting saw.
SMove at least 10 feet (3 meters) from fuel- ing site before starting engine.
STurn the engine off and let saw cool in a
straw, paper, etc. Slowly remove fuel cap and refuel unit.
SStore the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.
KICKBACK
WARNING: Avoid kickback which can result in serious injury. Kickback is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar con- tacts any object such as a log or branch, or when the wood closes in and pinches the saw chain in the cut. Contacting a foreign ob- ject in the wood can also result in loss of chain saw control.
SRotational Kickback can occur when the moving chain contacts an object at the up- per tip of the guide bar. This contact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back to- ward the operator.

Avoid Pinch-Kickback:
SBe extremely aware of situations or obstruc- tions that can cause material to pinch the top of or otherwise stop the chain.
SDo not cut more than one log at a time.
SDo not twist the saw as the bar is with- drawn from an undercut when bucking.
Avoid Pull-In:
SAlways begin cutting with the engine at full
speed and the saw housing against wood. S Use wedges made of plastic or wood.
Never use metal to hold the cut open. Kickback Path

REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.
SNever let the moving chain contact any ob-
ject at the tip of the guide bar.
SKeep the working area free from obstruc- tions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting through a particular log
or branch.
S Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback occurring. Follow manufacturer’s chain sharpening and main- tenance instructions. Check tension at regu-
