2. Attaching the Saw Chain
(1) Set the guide bar on the attachment bolt.
(2) Loop the saw chain over the sprocket while taking care
over the direction it is facing, and then set the saw chain
in the guide bar groove. (Fig. 4)
(3) Set the clip on the side cover in the housing, put on
the side cover, rotate the tension dial, align the chain's
tension pin with the hole on the guide bar and attach it
to the side cover. (Figs. 5 and 6)
CAUTION
If the knob is tightened before the tension dial is rotated,
the tension dial will be locked and it will not rotate.
(4) Gently press the top of the knob to insert it into the
screw hole, tighten it and then follow the instructions in
"Adjusting the Chain Tension".
CAUTION
○ When looping the saw chain over the sprocket, hold
the special nut in place to prevent the sprocket from
rotating. (Fig. 7)
○ If the special nut is accidently loosened or tightened,
cease use immediately and request repairs.
Using the chain saw as it is may prevent the chain
brake from operating normally and result in dangerous
situations.
ADJUSTING THE CHAIN TENSION
WARNING
○ Make sure switch is turned off and the plug disconnected
from the socket.
○ Always wear gloves when handling the saw chain.
○ The tightening tension for the special nut has been
adjusted to the optimal level. Do not loosen it or tighten
it under any circumstances.
(1) Raise the end of the guide bar and rotate the tension
dial to adjust the saw chain's tension. (Fig. 8)
(2) Adjust the saw chain tension so that the gap between
the edge of the chain's drive links and the guide bar is
between 0.5 mm and 1 mm when the chain is lightly
raised from the center of the guide bar. (Fig. 9)
(3) Once adjustment has been completed, raise the end of
the guide bar and fi rmly tighten the knob. (Fig. 8)
(4) Rotate the saw chain approximately one half of a
rotation while wearing gloves to reconfi rm that the
tension on the chain is correct.
CAUTION
If it is not possible to rotate the saw chain, check to
make sure that the chain brake has not been applied.
ATTACHING THE PLUG CLIP
The cord leading from the power plug is prevented from
being pulled out by the plug clip. (Fig. 10)
SWITCH OPERATIONS
WARNING
Do not secure the switch lock off button while it is
pressed. Accidently pulling the switch may result in the
chain saw unexpectedly starting up, which could lead to
injuries.
(1) Make sure that the chain saw is not switched on, and
then insert the power plug into a power socket.
(2) The chain saw is switched on when the lock off button is
pulled, and switched off when it is released. (Fig. 11)
CHECKING FOR CHAIN OIL EJECTION
○ The saw chain and guide bar are automatically
lubricated with chain oil when the chain saw is switched
on.
Check to make sure that chain oil is being applied from
the end of the guide bar normally. (Fig. 12)
○ If the oil is not ejected after rotating the chain for two or
three minutes, check to make sure that sawdust has not
collected around the oil outlet.
○ The amount of chain oil ejected can be adjusted with
the oil adjustment screw. (Fig. 13)
Cutting thick pieces of wood places a heavy load on the
saw chain, so make sure the amount of oil ejected is
increased at these times.
CAUTION
A soft-start function is activated when the chain saw is
switched on and the saw chain rotations start off slowly.
Wait until the rotations have built up before starting
work.
PROTECTION CIRCUIT
The chain saw is equipped with a protection circuit to
prevent it from being damaged. The motor will automatically
stop if excessive load is placed on the chain saw, such as
when forcing it to cut through hard wood, etc.
In this event, switch the chain saw off , isolate the reason for
the motor stopping, and then switch it on again and resume
work once the cause of the problem has been completely
eradicated.
Wait for at least two seconds after switching the chain saw
off following an automatic halt before switching it on again.

CUTTING PROCEDURES

1. General cutting procedures
(1) Switch ON the power while keeping the saw slightly
away from the wood to be cut. Start sawing only after
the unit has reached full speed.
(2) When sawing a slender piece of wood, press the base
section of the guide bar against the wood and saw
downward as shown in Fig. 14.
(3) When sawing a thick piece of wood, press the spike on
the front section of the unit against the wood and cut it
with a lever action while using the spike as a fulcrum as
shown in Fig. 15.
(4) When cutting wood horizontally, turn the unit body to
the right so that the guide bar is below and hold the
upper side of the side handle with your left hand. Hold
the guide bar horizontally and place the spike that is on
the front of the unit body on the lumbar. Using the spike
as a fulcrum, cut into the wood by turning the handle to
the right. (Fig. 16)
(5) When cutting into wood from the bottom, touch the
upper part of the guide bar to the wood lightly. (Fig. 17)
(6) As well as carefully studying the handling instructions,
ensure practical instruction in the operation of the
chain saw prior to use, or at least practice working with
the chain saw by cutting lengths of round timber on a
sawing trestle.
(7) When cutting logs or timbers which are not supported,
support them properly by immobilizing them during
cutting using a sawing trestle or other proper method.
CAUTION
○ When cutting wood from the bottom, there is a danger
that the unit body may be pushed back toward the user
if the chain strongly impacts with the wood.
