12. Wait 10-15 seconds.
13. Pull the throttle trigger lightly to set normal idle.
14. Use the product.
To start the engine when the fuel is
too hot
If the product does not start, the fuel can be too hot.
Note: Always use new fuel and decrease the operation
time during warm weather.
1. Put the product in a cool area away from open
sunlight.
2. Let the product cool down for 20 minutes at
minimum.
3. Press the air purge bulb again and again for 10-15
seconds.
4. Obey the procedure to start a cold engine. Refer to
To start a cold engine on page 16 .
To stop
• Push the stop switch to stop the engine.
Note: The stop switch automatically goes back to its
initial position.
To use a spiked bumper
A spiked bumper holds the wood as you cut. The spiked
bumper is a pivot between the engine body and the
guide bar.
1. Put the lower end of the spiked bumper at the
correct felling hinge width.
2. Push against the front handle with your left hand and
lift the rear handle with your right hand.
3. Cut until you get the correct felling hinge width.
Note: The felling hinge must have an equal
thickness.
4. Cut 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.
2. Make a notch 1/3 the diameter of the tree,
perpendicular to the direction of the fall. (Fig. 49)
WARNING: Read and understand the safety
chapter before you clean, repair or do
maintenance on the product.

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.
(Fig. 50) and (Fig. 51)
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 or
plastic to open the cut and let the tree fall along the
necessary line of fall. (Fig. 52)
6. When the tree starts to fall, remove the product from
the cut. Stop the motor, put the product down and
use the planned escape path. Be careful of limbs
falling from above and monitor your footing. (Fig. 53)
To limb a tree
1. Use larger limbs to hold the log off the ground.
2. Remove small limbs in one cut. (Fig. 54)
3. Cut branches that have tension from the bottom to
the top to prevent pinching the saw chain or the
guide bar.
To buck a log
• If the log has support along its full length, cut from
the top of the log (known as overbucking). (Fig. 55)
• If the log has support on one end, cut 1/3 the
diameter from below the log (known as
underbucking).
• If the log has support on the two ends, cut 1/3 the
diameter from the top. Complete the cut by
underbucking the lower 2/3 of the log to touch the
first cut. (Fig. 56)
• If you buck a log on a slope, always stay on the
uphill side of the log. Cut through the log while you
keep complete control of the product. Then release
the cutting pressure near the end of the cut while
tightly holding the rear handle and front handle. (Fig.
57)
