Kickback!!!

Kickback occurs when the

moving saw chain near

the upper quadrant of the

bar nose contacts a solid

object or is pinched

The greater the force of

the kickback reaction, the

more difficult it becomes

for the operator to control

the saw

confidential

Chain and Bar Color Code Marking

STIHL saw chain will have a green

or yellow tie strap to indicate if the

chain is low-kickback or other than

low-kickback

The bar will have two green or

yellow dots on the powerhead end

of the bar to identify if the bar is a

reduced kickback bar or not

confidential

Install the Bar and Chain

STIHL recommends the use of reduced

kickback bars and low kickback chains on

all STIHL chain saws

Yellow bar and chain combinations are for

trained professionals with extraordinary

cutting needs

Be sure the bar and chain are within the

recommended length for the model of

saw being assembled

Always wear gloves when handling saw

chain to protect your hands from the

sharp cutters

confidential

Install Bar & Chain: Quick Chain Adjuster

Install the tensioning gear and fasten the screw securely

The bar can be installed with the STIHL logo facing up or

Chain Adjustment

The 1130 saws have a front

chain tensioner

Most STIHL chain saws have a

side chain tensioner that is more

convenient to use

Saws come with a combination

wrench, commonly referred to as

a “Scrench”, to make bar and

chain service easy to do

confidential

Install Bar & Chain

Adjust the chain tension with the “Scrench” by holding up on

the nose of the bar, tightening the chain tension screw, then

tightening the nuts

confidential

Correct Chain Tension

With the chain brake

disengaged, pull the

chain through from the

top side and it should

rotate freely without any

slack appearing

If the chain goes from

tight to loose the

sprocket and chain may

not be of the same pitch,

or the sprocket and chain

may have excessive

wear and no longer have

the same pitch

confidential

Correct Chain Tension

Regardless of bar

length, check for

correct chain tension

by pulling up on the

chain at the center of

the bar

The tension is correct

when the bottom of the

drive link will just clear

the bar groove

confidential

Cutterless Chain for Service

For any chain saw, to properly tune the carb or verify running

RPM at idle and wide open throttle a bar and chain should be

installed

Cutterless chains are available to provide a safe way for the

service technician to do this without fear of the chain coming

into contact with anything

confidential

All Current Models of STIHL Chain Saws are Equipped with

the STIHL Quickstop® Chain Braking System

The chain is stopped and locked when the hand guard is

pushed toward the guide bar nose by the left hand – or when

the brake is activated by enough inertia in certain kickback

situations Brake
