PRUNING
WARNING: Be alert for and guard
against kickback. Do not allow the moving chain
to contact any other branches or objects at the
nose of the guide bar when pruning. Allowing
such contact can result in serious injury.
IMPORTANT POINTS
S Work slowly, keeping both hands firmly
gripped on the pruner. Maintain secure
footing and balance.
S Plan cut carefully. Check direction branch
will fall.
S Watch out for springpoles. Springpoles are
small size limbs which can catch the chain
and whip toward you or pull you off balance.
Use extreme caution when cutting small size
limbs or slender material.
S Watch out for branches immediately behind
the branch being pruned. If the chain hits the
rear branch, damage to the unit may occur.
S Be alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the
pruner when the tension in the wood fibers
is released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
S Long branches should be removed in
several pieces.
PRUNING TECHNIQUE
When ready to cut, accelerate to full throttle
and apply a light cutting pressure. DO NOT
use back and forth sawing action.
Pruning technique
Second cut
Third cut
Collar
First cut
1. Make the first cut 6 inches (15 cm) from
the tree trunk on the bottom of the limb.
Use top of guide bar to make this cut. Cut
1/3 through the diameter of the limb.
NOTE: When making the second and third
cuts, rest the foot of the pruner against the
tree limb that is being cut to prevent whipping
of the branch.
Foot
2. Next, move 2 -- 4 inches (5 -- 10 cm) far-
ther out on the limb and make a second
cut all the way through the limb.
3. Then, make a final cut leaving a 1 -- 2 inch
(2.5 -- 5 cm) collar from the trunk of the
tree to avoid damage to the tree.
OPERATING INSTRUCTIONS FOR
TRIMMER ATTACHMENT
OPERATING POSITION
Eye Protection
Long Pants
Heavy Shoes
ALWAYS WEAR:
Cut from your right to your left.
WARNING:
Always wear eye protec-
tion. Never lean over the trimmer head.
Rocks or debris can ricochet or be thrown into
eyes and face and cause blindness or other
serious injury.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise
and vibration. The cutting line will last longer
and will be less likely to “weld” onto the spool.
Always release the throttle trigger and allow
the engine to return to idle speed when not
cutting.
To stop engine:
S
Release the throttle trigger.
S Push and release the engine ON/STOP
switch.
TRIMMER LINE ADVANCE
The trimmer line will advance approximately 2
inches (5 cm) each time the bottom of the
trimmer head is tapped on the ground with the
engine running at full throttle.
