before refueling. Select bare ground for fueling and
move the chain saw at least
10
feet
(3
m) from fueling
spot before starting the engine (fig. 5a).

Check for fuel leakage while refueling and during
operation.
If
fuel or oil leakage
is
found, do not start or
run the engine until leak is fixed and spilled fuel has
been wiped away. Clothing with fuel on it has to be
changed immediately (this is a danger to your life!).
Avoid skin contact with fuel. Never loosen or remove
the cap of the fuel tank while the engine is running.
Starting
Do
not drop start.
This
method is very dangerous be-
cause you may lose control
of
the saw (fig. 6).
L
6a
Place the chain saw on firm ground or other solid
surface in an open area. Maintain a good balance and
secure footing. Place your right foot through the rear
handle opening and firmly grasp the front handle with
your left hand (fig. sa).
Be absolutely sure that guide bar and chain are clear
of you or all other obstructions and objects, including
the ground, because when the engine starts in semithrottle position, engine speed will be fast enough for
the clutch to engage the sprocket and turn the chain
which may cause a kickback.
Never attempt to start the saw when the guide bar is in
a cut or kerf.
When you pull the starter grip, don't wrap the starter
rope around your hands.
Do
not allow the grip to snap
back, but guide the starter rope slowly back to permit
the rope to rewind properly. Failure to follow this
procedure may result in injury
to
hand or fingers and
may damage the starter mechanism.

Important adjustments
WARNING1
At correct idle speed, chain should not tum. For di-
rections to adjust idle speed, see the appropriate
section
of
this
instruction manual.
Do
not use a saw with incorrect idle speed adjustment. Adjust the idle speed yourself according to
the appropriate section of this manual.
Have your MAKITA dealer check your saw and
make proper adjustments or repairs.
Check the saw chain tension frequently, especially
just after installing a new chain. New chains may
stretch more during their initial use. A properly ad-
justed saw chain can be pulled freely around the
guide bar by hand without sagging. Always stop
the engine and wear gloves when checking or
adjusting the chain tension.
Working conditions
Operate your chain saw only outdoors. Operate the
saw under good visibility and daylight conditions only.

Cutting instructions
Always hold the saw firmly with both hands when the
engine is running. Place your left hand on the tubular
handle and your right hand on grip and throttle lever.
Left-handers should follow these instructions too.
Wrap your fingers tightly around the handles, keeping
the handles cradled between your thumb and forefinger
(fig.
7).
With your hands in this position, you can best
oppose and absorb the push, pull and kickback forces
of
your saw without having it slip out of your grip (see
section of reactive forces). Make sure your chain saw
handle and grip are in good condition and free
of
moisture, pitch, oil or grease.
Always
start
a cut with the chain running at full speed
and the spike bar in contact with the wood.

When sawing, make sure that the saw chain does
not touch any foreign materials such as rocks,

Position the chain saw in such a way that your body is
clear of the cutting attachment whenever the engine is
running (fig. 10).
Don't put pressure on the saw when reaching the end
of
a cut. The pressure may cause the bar and rota!ing
chain to pop out of the cut or kerf, goout of control and
strike the operator or some other object.
If
the rotating
chain strikes some other object a reactive force (see
pages 10

An
understanding of the causes
of
these reactive
forces may help you avoid

control.
The most common reactive forces are
-
kickback,
-
pushback,
-
pull-in.
Kickback
Kickback occurs when the upper quadrant
of
the bar
nose contacts a solid object in the wood or is pinched
(fig. 11). The reaction of the cutting force of the chain
causes a rotational force of the chain saw in the direction
opposite tothe chain movement, mainly in the plane
of
the bar. This may fling the bar in an uncontrolled arc
towards the operator.
12
\-Y-w--
This reaction can occur in a fraction of a second and
under some circumstances, cause the guide bar and
chain to strike the operator with enough force to cause
severe or fatal injury.
It
may also occur during limbing.
It also occurs when the nose of the guide bar is pinched
unexpectedly, unintentionally contacts solid material
in the wood (fig.12) or is incorrectly used
to
begin a
plunge or boring cut.
Thegreatertheforceof the kickbackreaction, the more
difficult it becomesforthe operator to control the saw.
9
Many factors influence the occurence and
force
of
the kickback reaction. The type of bar and saw chain
you use is a factor in the force of the kickback reaction.
The speed of contact at which the cutter contacts
theobject.
Kickback force increase with the rate of impact..
The contact angle between the nose
of
the bar
and the foreign object (fig.
11).
Kickback is most pronounced in the upper quadrant
of the bar nose.
MAKITA chain types are designed to reduce kickback
forces.
The depth gauges:
Improper lowering of the depth gauges also increases
the risk of a kickback.
Saw chain cutter sharpness:
WARNING!
A dull improperly sharpened chain may increase
the
risk
of
kickback Always cut with a properfy
sharpened chain.

Devices for reducing the risk
of
kickback injury
MAKITA have developed a special chain brake to
reduce the risk of kickbacks.
This chain brake increases the safety factor on the
job, e.g. when the saw suddenly bucks upwards the
chain stops rotating within a fraction of a second. A
deflection guard on the disengaging lever of the chain
brake and a scoop rear handle ensure that the operator's hands are fully protected at all times.
Kickback tendency increases as the radius or size of
the guide bar nose increases. MAKITA have devel-
oped guide bars with small nose radius, to reduce the
kickback tendency.
No
chain brake prevents
ki
These brakes are designed only to stop the chain,
if
activated.
To
ensure a proper operation of the chain brake,
it
must be properly maintained. Furthermore, there
must
be
asufficient distance between the operator
and the bar to ensure that the chain brake has
sufficient time to activate and stop the chain before
potential contact with the operator.
I
13
To
avoid kickback
The best protection from personal-injury that may
result from kickback is to avoid kickback situations:
1.
Hold the chain saw firmly with both hands and
maintain a secure grip.
2.
Be aware of the location of the guide bar nose at
all times.
c"
_.
.
3.
Never bring the nose of the guide bar in contact
with any object.
Do
not cut limbs with the nose
of
the guide bar. Be especially careful with small,
tough limbs, small size brush and saplings which
may easily catch the chain.
4.
Don't overreach.
5.
Don't cut above shoulder height.
6.
Begin cutting and continue at full throttle.
7.
Cut onti one
tog
at a time.
8.
Use extreme caution when re-entering a previous
cut.
9.
Do
not attempt plunge cuts (see page
13)
if
you
are not experienced with these cutting techniques.
10.
Be alert for shifting of the log or other forces that
may cause the cut to close and pinch the chain.
11.
Maintain saw chain properly. Cut with a correctly
sharpened, properly tensioned chain at all times.
12.
Stand to the side of the cutting path of the chain
saw.
10
Pushback:
Pushback occurs when the chain on the top
of
the bar
is suddenly stopped when
it
is pinched, caught or
encounters
a
foreign object in the wood. The reaction
of the chain drives the saw straight back toward the
operator causing
loss
of saw control. Pushback fre-
quently occurs when the top of the bar is used
for
cutting (fig.
14).
14
To
avoid
pushback
1.
Be alert to forces or situations that may cauE
material
to
pinch the top of the chain.
2.
Do
not cut more than one log at a time.
3.
Do
not twist the saw when withdrawing the bar
from a plunge cut or under buck cut (figures
25
to
27
and
33,
pages 13 and
15),
because the chain
can pinch.
Pull-in:
Pull-in occurs when the chain on the bottom of the bar
is suddenly stopped. The chain on the bottom
of
the
bar stops when it is pinched, caught or encounters a
foreign object in the wood (see fig.
15).
The reaction of

to lose control.
Pull-in frequently occurs when the spike bar of the
saw is not held securely against the tree or limb and
when the chain is not rotating at full speed before it
contacts the wood.
