Oregon®91 VX saw chains may be capable of kickback that could
result in serious injury to the saw operator or bystanders.
Although these chains have features designed to reduce kickback energies, these
are NOT low-kickback chains. Do not use Oregon®91 VX chains unless you have experi-
ence and specialized training for dealing with kickback. Saw chain with lower kickback
potential is available.
Failure to follow filing instructions can
increase the level of kickback which
can result in severe injury to the saw operator or bystanders.
*Do not exceed the depth-gauge setting shown above
*Always file depth gauges back to their original rounded
or ramped shape after lowering
If you cut abrasive woods such as railroad ties, or if you cut in the following
kinds of locations: sandy areas, partially logged areas after skidder extrac-
tion, fire-damaged areas, or any place where the wood has become dirty
– then you may prefer the MultiCut™versions of Oregon
®
chains. MultiCut™
chains have extra-heavy-duty chrome plating applied with an advanced
plating process to withstand these kinds of tough dirty conditions. Contact
Oregon
®
or your authorized Oregon
®
distributor for further information on
MultiCut™chains.
