nOTE: If too much force is applied while making a cut the
pruner will turn off. To restart pruner, you must release the
lock off lever and the trigger switch before the pruner will
restart. Begin your cut again this time with less force. Allow
the pruner to cut at its own pace.
Common Cutting Techniques
Limbing
Removing the branches from a fallen tree. When limbing,
leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut. Branches under tension
should be cut from the bottom of the branch towards the
top to avoid binding the pruner as shown below. Trim limbs
from opposite side keeping tree stem between you and
pruner. Never make cuts with pruner between your legs or
straddle the limb to be cut.
Bucking
WARNING: Recommend that first time users should
practice cutting on a pruner horse.
Cutting a felled tree or log into lengths. How you should cut
depends on how the log is supported. Use a pruner horse
whenever possible as shown below.
1. Always start a cut with the pruner chain running at
full speed.
2. Place the ribbed bumper
area of the initial cut as shown below.
3. Turn the pruner on then rotate the pruner chain and bar
down into the tree, using the ribbed bumper as a hinge.

4. Once the pruner gets to a 45 ° angle, level the pruner
again and repeat steps until you cut fully through.
5. When the tree is supported along its entire length, make
a cut from the top (overbuck), but avoid cutting the earth
as this will dull your pruner quickly.

When supported at one end first, cut 1/3 the diameter
from the underside (underbuck). Then make the finishing
cut by overbucking to meet the first cut as shown below.

When supported at both ends. First, cut 1/3 down from the
top overbuck. Then make the finished cut by underbucking
the lower 2/3 to meet the first cut as shown below.
•
When on a slope always stand on the uphill side of
the log. When "cutting through", to maintain complete
control reduce the cutting pressure near the end of the
cut without relaxing your grip on the pruner handles.
Don't let the chain contact the ground. After completing
the cut, wait for the pruner chain to stop before you
move the pruner. Always stop the motor before moving
from cut to cut.
MAINTENANCE
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
