OPERATING INSTRUCTIONS
OPERATING TIPS
• Avoid blade thrust. Blade thrust can result in severe injury or
death.
• Do not operate the bladed pruner while in a tree, on a ladder or
any other unstable work surface, or in any awkward position. You
may lose control of the bladed pruner causing severe injury.
• Do not extend your arms above shoulders when using the bladed
pruner.
• Seek professional help if you are facing conditions beyond your
ability.
• Trimming a tree is the process of cutting limbs from a living tree.
Make sure your footing is firm. Keep your feet apart. Divide your
weight evenly on both feet.
To trim a limb (pruning):
1. Using the top edge of the blade (Fig. 7), score the bottom of
the branch to a depth of up to about a half inch for Cut 1. This
will help keep the bark from ripping away from the tree when
the branch is cut.
NOTE: If the score is too deep, the branch will bend and bind the
blade in the cut making the blade difficult to pull out.
2. Using the bottom edge of the blade (Fig. 8), align the blade
with Cut 1, lower the pruner until the blade contacts the
branch, and cut through the branch in one slow, steady motion
(Cut 2).

Cut 1
WARNING:
Blade thrust may occur when the spinning
blade contacts an object that it does not immediately cut.
Blade thrust can be violent enough to cause the unit
and/or operator to be propelled in any direction, and
possibly lose control of the unit. Blade thrust can occur
without warning if the blade snags, stalls or binds. This is
more likely to occur in areas where it is difficult to see the
material being cut.
WARNING:
To avoid serious personal injury, make sure
you NEVER stand directly beneath the branch being cut or
in the arc of its detachment.

beneath the blade aligns between the locking teeth (Fig. 10).
5. Insert the long end of the provided Allen wrench between the
Locking Teeth and into the Locking Hole (Fig. 10).
6. While holding the Allen wrench in the hole, remove the nut by
turning it in a
CLOCKWISE direction with a 13 mm socket wrench.
NOTE: This nut is reverse-threaded to compensate for the rotation
of the cutting blade. Be careful to turn the wrench in a
CLOCKWISE direction to loosen the nut.
