chain efficiency is too high, the 2 lights on the right
side of the power meter will be on. The saw chain
efficiency is correct when the 2 lights in the center of
the power meter are on.
•
For low saw chain efficiency, increase the saw chain
tension.
•
For high saw chain efficiency, decrease the saw
chain tension.
Note: Use the saw chain efficiency test indicator as a
guide only. Always examine the product and do the
necessary maintenance.
To start the motor
1. Move the front hand guard forward to engage the
chain brake.
2. Install the battery pack. See
pack on page 11 .
3. Press the power button until the light is on.
4. Hold the rear handle with your right hand and the
front handle with your left hand.
5. Pull the front hand guard rearward in the direction of
the front handle to disengage the chain brake.
6. Press and hold the trigger lockout with your right
hand.
7. While you continue to hold the trigger lockout,
squeeze and hold the trigger.
8. Continue to squeeze the trigger to operate. Squeeze
the trigger lightly for lower speed. Squeeze the
trigger more for higher speed.
9. Use the product.
To stop the motor
1. Release the trigger.
2. Push the power button until the light is off.
To use a spike bumper
A spike bumper prevents kickbacks and holds the wood
as you cut. The spike bumper is a pivot between the
motor body and the guide bar.
1. Put the lower end of the spike bumper at the correct
hinge width.
2. Press, with your left hand, against the front handle
while you lift the rear handle with your right hand.
3. Saw until you get the correct hinge width.
Note: The hinge must have an equal thickness.
4. Saw more than half of the diameter and then put the
felling wedge into the saw cut.
To fell a tree
1. Remove dirt, stones, loose bark, nails, staples and
wire from the tree.

To install the battery
2. Make a notch 1/3 the diameter of the tree,
perpendicular to the direction of the fall.
3. Make the lower horizontal notch cut. This helps
prevent pinching the saw chain or the guide bar
when the second notch is made.
4. Make the felling back cut (X) a minimum of 50 mm (2
in) higher than the horizontal notch cut. Keep the
felling back cut parallel to the horizontal notching cut
so sufficient wood is left to be a hinge. Do not cut
through the hinge. The hinge wood keeps the tree
from twisting and falling in the incorrect direction.
5. As the felling back cut nears the hinge, the tree
starts to fall. Make sure that the tree can fall in the
correct direction and not rock rearward and pinch the
saw chain. Stop the cut before the felling back cut is
complete to prevent this. Use wedges of wood,
plastic or aluminum to open the cut and let the tree
fall along the necessary line of fall.
