Kickback Safety Features
WARNING: The following features are included
on your saw to help reduce the hazard of kickback;
however such features will not totally eliminate this
dangerous reaction. As a pruner user do not rely
only on safety devices. You must follow all safety
precautions, instructions, and maintenance in this
manual to help avoid kickback and other forces which
can result in serious injury.
•
Reduced‑Kickback Guide Bar, designed with a small radius
tip which reduces the size of the kickback danger zone on
bar tip. A reduced ‑ kickback guide bar is one which has
been demonstrated to significantly reduce the number and
seriousness of kickbacks when tested in accordance with
safety requirements for electric pruners.
•
Low‑Kickback Chain, designed with a contoured depth
gauge and guard link which deflect kickback force and
allow wood to gradually ride into the cutter. A low‑kickback
chain is a chain which has met kickback performance
requirements of ANSI B175.1–2012.
•
Do not operate pruner while in a tree, on a ladder, on a
scaffold, or from any unstable surface.
•
Hold tool by insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden
wiring. Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
•
Do not attempt operations beyond your capacity or
experience. Read thoroughly and understand completely all
instructions in this manual.
•
Before you start pruner, make sure saw chain is not
contacting any object.
•
Do not operate a pruner with one hand! Serious injury to the
operator, helpers, or bystanders may result from one handed
operation. A pruner is intended for two‑handed use only.
•
Keep the handles dry, clean, and free of oil or grease.
•
Do not allow dirt, debris, or sawdust to build up on the
motor or outside air vents.
•
Stop the pruner before setting it down.
•
Do not cut vines and/or small under brush.
•
Use extreme caution when cutting small size brush and
saplings because slender material may catch the saw chain
and be whipped toward you or pull you off balance.
