Maintenance Requirements
The maintenance instructions in this manual are
based on the application of the recommended 2-
stroke fuel-oil mixture (see also instruction
"Fuel"). Deviations from this recommendation
regarding quality and mixing ratio of fuel and oil
may require shorter maintenance intervals.
Limitations
This Emission Control Systems Warranty shall
not cover any of the following:
1. repair or replacement required because of
misuse, neglect or lack of required mainte‐
nance
2. repairs improperly performed or replace‐
ments not conforming to STIHL Limited
specifications that adversely affect perform‐
ance and/or durability, and alterations or
modifications not recommended or approved
in writing by STIHL Limited

40 CSA Standard
CSA-Standard Z62.3-11 sets certain perform‐
ance and design criteria related to chain saw
kickback. To comply with CSA Z62.3-11:
a. saws of class A and C shall not exceed 45°
computed kickback angle (CKA). Operation
of the chain brake may be taken into consid‐
eration for compliance with this requirement
(CKA ). If the chain has stopped before the
wb
bar has reached the maximum deflection, the
requirement also is complied with if this
lower computed kickback chain stopping
angle (CKA ) does not exceed the limit of
cs
45°
b. saws of class B shall not exceed 25° CKA
under the conditions as mentioned above
and have a guide bar with a nose radius no
greater than 25 mm. An automatic chain
brake activated upon kickback is mandatory,
so is a low kickback saw chain
The computed kickback angles are measured by
applying a computer program to test results from
a kickback test machine.
WARNING
In order to comply with the computed kickback
angle requirements of CSA Z62.3‑11, use only
the following cutting attachments:
► a bar and chain combination as listed in this
instruction manual
► other replacement saw chains for use on spe‐
cific powerheads or
► a low-kickback saw chain
STIHL offers a variety of 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 obtain
higher productivity or sharpening ease but may
result in a higher kickback tendency.
Please ask your STIHL dealer to properly match
your powerhead with the appropriate bar/chain
combinations to reduce the risk of kickback
injury. Low-kickback saw chains are recommen‐
ded for all powerheads. See the charts of the
STIHL Bar and Chain Information for details.
