GENERAL SAFETY RULES
WARNING!
Read all instructions
Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
The term “power tool” in all of the warnings listed below
refers to your mains operated (corded) power tool or battery
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust.
Power tools create sparks which may ignite the
dust of fumes.
c) Keep children and bystanders away while operating
a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk
of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts.
Damaged or entangled cords increase the risk
of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication.
A moment of inattention while operating power
tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in
the off position before plugging in.
Carrying power tools with your finger on the
switch or plugging in power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on.
5
A wrench or a key left attached to a rotating part
of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance
at all times.
This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts.
Loose clothes, jewellery or long hair can be caught
in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used.
Use of these devices can reduce dust related
hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better and
safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off.
Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools.
Such preventive safety measures reduce the risk
of starting the power tool accidentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation.
If damaged, have the power tool repaired before
use.
Many accidents are caused by poorly maintained
power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions
and the work to be performed.
Use of the power tool for operations different from
intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts.
This will ensure that the safety of the power tool
is maintained.

ADJUSTING THE CHAIN TENSION
1. Loosen the bolt securing the chain cover with the
accessory wrench, as shown in Fig. 1. It is not
necessary to remove the bolt.
2. While lifting the tip of the guide bar, turn the
adjusting screw with the accessory minus-head
screwdriver to adjust the chain tension, as shown
in Fig. 2. The chain tension is increased by turning
6
English
the adjusting screw clockwise, and slackened by
turning it counterclockwise.
3. The chain tension must be adjusted so that a 0.5–
1.0 mm gap appears between the chain drive links
and the guide bar when the chain is lightly raised
at the center section of the guide bar as shown in
Fig. 3.
4. When chain tension adjustment is completed,
retighten the bolt securing the chain cover.
CAUTION
Due to the sharpness of the chain, protect your
hands when checking the tension or servicing.
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 the slender piece of wood, press the
base section of the guide bar against the wood and
saw downward as shown in Fig. 4.
(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 lever action while using the spike
as a fulcrum as shown in Fig. 5.
(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
lumber. Using the spike as a fulcrum, cut into the
wood by turning the handle to the right. (Fig. 6)
(5) When cutting into wood from the bottom, touch the
upper part of the guide bar to the wood lightly.
(Fig. 7)
(6) In addition of careful study of the handling
instructions, take practical instruction in the operation
of the chain saw prior to use, or at least to 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 not to move
during cutting by a sawing trestle or another proper
methods.
CAUTIONS
䡬 When cutting wood from the bottom, there is the
danger that the unit body may pushed back toward
the user if the chain strongly hits the wood.
䡬 Do not cut all the way through the wood by starting
from the bottom since there is the danger of the
guide bar flying up out of control when the cut is
finished.
䡬 Always prevent the operating chain saw from
touching the ground or wire fences.
2. Branch cutting
(1) Cutting branches from a standing tree:
A thick branch should initially be cut off at a point
away from the trunk of the tree.
First cut in about one third of the way from below,
and then cut off the branch from above. Finally, cut
off the remaining portion of the branch even with
the trunk of the tree. (Fig. 8)
CAUTIONS
䡬 Always be careful to avoid falling branches.
䡬 Always be alert for chain saw recoil.
(2) Cutting branches from fallen trees:
First cut off branches that do not touch the ground,
then cut off those which touch the ground. When
cutting thick branches that touch the ground, first
cut in about half of the way from above, then cut
the branch off from below. (Fig. 9)
CAUTIONS
䡬 When cutting off branches which touch the ground,
be careful that the guide bar does not become
bound by pressure.
䡬 In the final stage of cutting, beware of the log
suddenly rolling.
3. Log cutting
When cutting a log positioned as shown in Fig. 10,
first cut in about one third of the way from below,
then cut down all the way from above.
When cutting a log that straddles a hollow as shown
in Fig. 11, first cut in about two thirds of the way
from above, then cut upward from below.
CAUTIONS
䡬 Be careful that the guide bar does not become
bound in the log by pressure.
䡬 When working on inclined ground, be sure to stand
on the uphill side of the log. If you stand on the
downhill side, the cut-off log may roll toward you.
4. Felling trees:
(1) Undercut (q as shown in Fig. 12):
Make undercut facing direction which you want tree
to fall.
Depth of undercut should be 1/3 of tree’s diameter.
Never fell trees without proper undercut.
(2) Backcut (w as shown in Fig. 12):
Make backcut about 5 cm above and parallel to the
horizontal undercut.
If the chain is bound during cutting, stop the saw
and use wedges to free form it. Do not cut through
the tree.
CAUTIONS
䡬 Trees should not be felled in a manner that would
endanger any person, strike any utility line or cause
any property damage.
䡬 Be sure to stand on the uphill side of the terrain
as the tree is likely to roll or slide downhill after
it is felled.
SHARPENING OF CHAIN BLADE
CAUTION
Ensure the power source has been disconnected from
the tool before performing the steps below. Wear
gloves to protect your hands.
Dull and worn chain blades will decrease the efficiency
of the tool and place unnecessary overload on the
motor and various parts of the machine. In order to
maintain optimum efficiency, it is necessary to check
the chain blades often and keep them properly
sharpened and adjusted. Blade sharpening and depth
gauge adjustment should be accomplished at the
center of the guide bar with the chain properly mounted
to the machine.
