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.

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 saw horse
wheneverpossible as shownbelow.
1. Always start a cut with the pruner chain running at
fullspeed.
2. Place the ribbed bumper
21
of the pruner behind the 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.
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
2
and the trigger switch
1
before the pruner will
restart. Begin your cut again, this time with less force. Allow the
pruner to cut at its ownpace.
