Warning – Partner Formula 400 Chrome 2007 User Manual

Page 36

Do 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.

With 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

Have 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.

Make certain the saw chain stops moving

when the throttle trigger is released. For

correction, refer to CARBURETOR AD-

JUSTMENTS.

Never modify your saw in any way. Use

only attachments supplied or specifically

recommended by the manufacturer.

Keep the handles dry, clean, and free of oil

or fuel mixture.

Keep fuel and oil caps, screws, and fas-

teners securely tightened.

Use only PartnerR

accessories and re-

placement parts as recommended.

HANDLE FUEL WITH CAUTION

Do not smoke while handling fuel or while

operating the saw.

Eliminate 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.

Mix 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.

Move at least 10 feet (3 meters) from fuel-

ing site before starting engine.

Turn the engine off and let saw cool in a

non-combustible area, not on dry leaves,

straw, paper, etc. Slowly remove fuel cap

and refuel unit.

Store 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.

Rotational 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.

Pinch-Kickback can occur when the the

wood closes in and pinches the moving

saw chain in the cut along the top of the

guide bar and the saw chain is suddenly

stopped. This sudden stopping of the

chain results in a reversal of the chain

force used to cut wood and causes the

saw to move in the opposite direction of the

chain rotation. The saw is driven straight

back toward the operator.

Pull-In can occur when the moving chain

contacts a foreign object in the wood in the

cut along the bottom of the guide bar and the

saw chain is suddenly stopped. This sudden

stopping pulls the saw forward and away

from the operator and could easily cause the

operator to lose control of the saw.

Avoid Pinch--Kickback:
S

Be extremely aware of situations or obstruc-

tions that can cause material to pinch the top

of or otherwise stop the chain.

Do not cut more than one log at a time.

Do not twist the saw as the bar is with-

drawn from an undercut when bucking.

Avoid Pull--In:
S

Always begin cutting with the engine at full

speed and the saw housing against wood.

Use wedges made of plastic or wood.

Never use metal to hold the cut open.

Kickback Path

Avoid obstructions

Clear the working area

REDUCE THE CHANCE OF

KICKBACK

Recognize that kickback can happen.

With a basic understanding of kickback,

you can reduce the element of surprise

which contributes to accidents.

Never let the moving chain contact any ob-

ject at the tip of the guide bar.

Keep 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.
