6 Kickback and Other Reactive Forces ￭ An improperly maintained chain brake may increase the time needed to stop the chain after activation, or may not activate at all. For the Quickstop chain brake to reduce the risk of kickback injury, it must be properly maintained and in good working order. - Read and follow the instructions on engaging and disengaging the chain brake, @ 13, and maintaining and repairing it, @ 13.3. 2. Low Kickback Saw Chain and Reduced Kickback Bars STIHL offers a variety of guide bars and chains. STIHL reduced kickback bars and low kickback chains are designed to reduce the risk of kickback injury. Other chains are designed to achieve higher cutting performance or sharpening ease, but are more prone to kickback and may kick back with more energy, making it more difficult to control the chain saw. STIHL has developed a color code system to help you identify the STIHL reduced kickback bars and low kickback chains. - Cutting attachments with green labels on the packaging are designed to reduce the risk of kickback injury. - Matching green-marked or labeled chain saws with greenlabeled bars and green-labeled chains provides compliance with the computed kickback angle requirements of the chain saw standards when the products are in their original condition. - Products with yellow labels are for users with extraordinary cutting needs, who have experience and specialized training for dealing with kickback. STIHL recommends the use of its green-labeled reduced kickback bars, green-labeled low kickback chains and a chain saw equipped with a STIHL Quickstop chain brake for both experienced and inexperienced operators. STIHL recommends green-labeled bars and chains for all chain saws. See your "STIHL Bar and Chain Information" leaflet for details. English New bar and chain combinations may be developed after publication of this literature, which will, in combination with certain chain saws, comply with the chain saw standards as well. WARNING ￭ Use of bar and chain combinations not listed in the STIHL Bar and Chain Information leaflet (or other combinations that do not comply with the chain saw standards) may increase kickback forces as well as the propensity for kickback and increase the risk of kickback injury. - Please ask your authorized STIHL servicing dealer to properly match your chain saw with the appropriate bar and chain combination to reduce the risk of kickback injury. ￭ Reduced kickback bars and low kickback chains do not prevent kickback, but they are designed to reduce the risk of kickback injury. - STIHL recommends green-labeled bars and greenlabeled chains for all chain saws and all users. ￭ Even if your saw is equipped with a Quickstop chain brake, a reduced kickback bar and/or low kickback chain, this does not eliminate the risk of injury from kickback. - Observe all safety precautions discussed in this manual to avoid kickback situations. a. Low Kickback Saw Chain Some types of chain have specially designed components to reduce the propensity for kickback and the force of kickback if it occurs. STIHL has developed low kickback chain for your chain saw. A "low kickback chain" is a chain that has met the kickback performance requirements of ANSI/OPEI B175.1 when tested according to the provisions specified in ANSI/OPEI B175.1. WARNING ￭ Some low kickback chains have not been tested with all chain saw and bar combinations. There are potential saw, bar and low kickback chain combinations which have not 0458-787-8621-A 23

6 Kickback and Other Reactive Forces

￭

An improperly maintained chain brake may increase the

time needed to stop the chain after activation, or may not

activate at all. For the Quickstop chain brake to reduce the

risk of kickback injury, it must be properly maintained and

in good working order.

–

Read and follow the instructions on engaging and

disengaging the chain brake,

13, and

maintaining and repairing it,

13.3.

2. Low Kickback Saw Chain and Reduced Kickback Bars

STIHL offers a variety of guide bars and chains. STIHL

reduced kickback bars and low kickback chains are

designed to reduce the risk of kickback injury. Other chains

are designed to achieve higher cutting performance or

sharpening ease, but are more prone to kickback and may

kick back with more energy, making it more difficult to

control the chain saw.

STIHL has developed a color code system to help you

identify the STIHL reduced kickback bars and low kickback

chains.

–

Cutting attachments with green labels on the packaging

are designed to reduce the risk of kickback injury.

–

Matching green-marked or labeled chain saws with green-

labeled bars and green-labeled chains provides

compliance with the computed kickback angle

requirements of the chain saw standards when the

products are in their original condition.

–

Products with yellow labels are for users with

extraordinary cutting needs, who have experience and

specialized training for dealing with kickback.

STIHL recommends the use of its green-labeled reduced

kickback bars, green-labeled low kickback chains and a

chain saw equipped with a STIHL Quickstop chain brake for

both experienced and inexperienced operators.

STIHL recommends green-labeled bars and chains for all

chain saws. See your "STIHL Bar and Chain Information"

leaflet for details.

New bar and chain combinations may be developed after

publication of this literature, which will, in combination with

certain chain saws, comply with the chain saw standards as

well.

WARNING

￭

Use of bar and chain combinations not listed in the STIHL

Bar and Chain Information leaflet (or other combinations

that do not comply with the chain saw standards) may

increase kickback forces as well as the propensity for

kickback and increase the risk of kickback injury.

–

Please ask your authorized STIHL servicing dealer

to properly match your chain saw with the

appropriate bar and chain combination to reduce the

risk of kickback injury.

￭

Reduced kickback bars and low kickback chains do not

prevent kickback, but they are designed to reduce the risk

of kickback injury.

–

STIHL recommends green-labeled bars and green-

labeled chains for all chain saws and all users.

￭

Even if your saw is equipped with a Quickstop chain

brake, a reduced kickback bar and/or low kickback chain,

this does not eliminate the risk of injury from kickback.

–

Observe all safety precautions discussed in this

manual to avoid kickback situations.

a. Low Kickback Saw Chain

Some types of chain have specially designed components to

reduce the propensity for kickback and the force of kickback

if it occurs. STIHL has developed low kickback chain for your

chain saw.

A "low kickback chain" is a chain that has met the kickback

performance requirements of ANSI/OPEI B175.1 when

tested according to the provisions specified in ANSI/OPEI

B175.1.

WARNING

￭

Some low kickback chains have not been tested with all

chain saw and bar combinations. There are potential saw,

bar and low kickback chain combinations which have not
