ENGLISH
Saw Chain Sharpness

CAUTION: Sharp chain. Always wear protective gloves
when handling the chain. The chain is sharp and can cut
you when it is notrunning.
IMPORTANT: The chain cutters will dull immediately if they
touch the ground, stones, masonry or a nail whilecutting.
To get the best possible performance from your chain saw it
is important to keep the teeth of the saw chain sharp. Chain
sharpening services are available from your nearest STANLEY
FATMAX servicecentre.
NOTE: Each time the saw chain is sharpened, it loses some
of the reduced kickback qualities and extra caution should be
used. It is recommended that a saw chain be sharpened no
more than fourtimes.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
The charger and battery pack are notserviceable.

• 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 chain saw handles. Don’t let the
chain contact the ground. After completing the cut, wait
for the saw chain to stop before you move the chain saw.
Always stop the motor before moving from cut tocut.
binding the chainsaw as shown below. Trim limbs from opposite
side keeping tree stem between you and saw. Never make cuts
with saw between your legs or straddle the limb to becut.

WARNING: Recommend that first time users should
practice cutting on a saw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 saw chain running at fullspeed.
2. Place the bottom spike
23
of the chainsaw behind the area
of the initial cut as shownbelow.
3. Turn the chainsaw on then rotate the saw chain and bar
down into the tree, using the spike as ahinge.
4. Once the chainsaw gets to a 45° angle, level the chainsaw
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 saw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.
