72LGX/JGX, 73LGX/JGX, and 75LGX/JGX Super
Guard
®
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
®
72LGX/JGX, 73LGX/JGX, or
75LGX/JGX Super Guard
®
chains unless you have experience 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, skidded wood, fire damaged areas, par-
tially logged areas after a skidder, or any place where wood is dirty, we recommend you
use 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. It also allows you to maintain your saw chain without the need of
any special tools. Contact OREGON
®
or your authorized OREGON
®
distributor for further
information on MultiCut™ chains.

Which cutter sequence is best, standard or skip?
What type of cutting do you do? The cutter sequence to use:
I cut "non-fibrous" woods of average size, with guide bars up to 24" Standard sequence (72LGX, 73LGX, 75LGX)
I cut fibrous woods, such as cedar or hemlock Skip sequence (72JGX, 73JGX, 75JGX)
I cut large wood using very long bars, approximately 28" or longer Skip sequence (72JGX, 73JGX, 75JGX)
