warning

Use of replacement saw chain and/or guide bar other than that specified, or operation without the “tip guard” in place, may cause severe kickback resulting in serious injury.

Only use replacement guide bar and saw chain that has been designated as meeting the ANSI B175.1 - 2000 and/or CSA Z62.3 requirements. All of the guide bar and chain combinations listed above meet the ANSI B175.1-200 and/or CSA Z62.3 requirements.

IMPORTANT

Chain and guide bar gauge size must be identical. Use Bar/Chain combinations shown in table above.

IMPORTANT

If your kick guard is damaged or lost, contact your Echo dealer for a replacement. For the name of the Echo dealer nearest you, Call: 1-800-432-ECHO (3246) or on the web at www.echo-usa.com.

Refer to your Chain Saw Safety Manual for kick guard application information.

GUIDE BAR

(Low-kickback) Replacement guide bars.

The following guide bars may be considered to have equivalent kickback energy.

Sprocket nose guide bars of the same length and nose radius, same pitch and having the same number of teeth.

Hard nose guide bars of the same length and nose radius as a sprocket nose bar.

SAW CHAIN

(Low-kickback)

CAUTION

Do not use replacement saw chain unless it has been designated as meeting the ANSI B175.1 - 2000 kickback performance requirements, when tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI B175.1 - 2000.
