Large panels tend to sag under their own weight.
Supports must be placed under the panel on both
sides, near the line of cut and near the edge of the
panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce narrow
kerf causing excessive friction, blade binding and
kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making the cut.
If blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing walls
or other blind areas.
The protruding blade may cut objects that can cause
kickback.
Lower guard function
a) Check the lower guard for proper closing before
each use. Do not operate the saw if the lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the open
position.
If the saw is accidentally dropped, the lower guard may
be bent.
Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the blade
or any other part, in all angles and depths of cut.
b) Check the operation of the lower guard spring. If
the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
c) The lower guard may be retracted manually only
for special cuts such as “plunge cuts” and
“compound cuts”. Raise the lower guard by the
retracting handle and as soon as the blade enters
the material, the lower guard must be released.
For all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering
the blade before placing the saw down on bench
or floor.
An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path. Be
aware of the time it takes for the blade to stop after
switch is released.
ADDITIONAL SAFETY WARNINGS
1. Wear earplugs to protect your ears during operation.
2. Use only blade diameter specified on the machine.
3. Do not use any abrasive wheel.
4. Do not use saw blades which are deformed or cracked.
5. Do not use saw blades made of high speed steel.
6. Do not use saw blades which do not comply with the
characteristics specified in these instructions.
7. Do not stop the saw blades by lateral pressure on the
disc.
8. Always keep the saw blades sharp.
9. Ensure that the lower guard moves smoothly and freely.
10. Never use the circular saw with its lower guard fixed in
the open position.
11. Ensure that the retraction mechanism of the guard
system operates correctly.
12. Never operate the circular saw with the saw blade
turned upward or to the side.
13. Ensure that the material is free of foreign matters such
as nails.
14. The saw blades range should be from 165mm to
162mm.
15. Pull out battery before carrying out any adjustment,
servicing or maintenance.
16. Be careful of brake kickback.
This circular saw features an electric brake that
functions when the switch is released. As there is some
kickback when the brake functions, be sure to hold the
main body securely.
17. Ensure that the switch is in the OFF position. If the
battery installed to power tool while the switch is in the
ON position, the power tool will start operating
immediately, which could cause a serious accident.
18. Avoid cutting in the state where the base has floated up
from the material.
When blade is binding, or when interrupting a cut for
any reason, release the trigger and hold the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from
the work or pull the saw backward while the blade is in
motion or KICKBACK may occur. Investigate and take
corrective actions to eliminate the cause of blade
binding.
19. Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight (Fig.3). Supports must be
placed under the panel on both sides, near the line of
cut and near the edge of the panel as shown in Fig.2.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the saw
on the work piece, the saw shall be rested on the larger
portion and the smaller piece cut off.
20. Use extra caution when making a “Pocket Cut” into
existing walls or other blind areas. The protruding blade
may cut objects that can cause KICKBACK.
NEVER place your hand or fingers behind the saw
(Fig.4). If kickback occurs, the saw could easily jump
backwards over your hand, possibly causing severe
injury.
21. WARNING: It is important to support the work piece
properly and to hold the saw firmly to prevent loss of
control which could cause personal injury. Fig.5
illustrates typical hand support of the saw.
22. Place the wider portion of the saw base on that part of
the work piece which is solidly supported, not on the
section that will fall off when the cut is made. As
examples, Fig.6 illustrates the RIGHT way to cut off the
end of board, and Fig.7 the WRONG way. If the work
piece is short or small, clamp it down. DON’T TRY TO
HOLD SHORT PLACES BY HAND!
23. Never attempt to saw with the circular saw held upside
down in a vise.
This is extremely dangerous and can lead to serious
accidents. (Fig.8)
24. When using the guide, do not attempt an inclined cut
which would allow the cut material to slip between the
saw blade and guide. Doing so could result in injury.
(Fig.9)
25. Should lever remain loosened, it will create a very
hazardous situation. Always thoroughly clamp it.
(Fig.15)
26. It is very hazardous to allow the incline lever and incline
wing nut to remain loosened. Always thoroughly clamp
it. (Fig.25, 26)
27. Prior to cutting operation, make sure the material you
are going to cut. If the material to be cut is expected to
generate harmful / toxic dusts, make sure the dust bag
or appropriate dust extraction system is connected with
dust outlet tightly.
Wear the dust mask additionally, if available.
○ Before starting to saw, confirm that the saw blade has
attained full-speed revolution.
○ Should the saw blade stop or make an abnormal noise
while operating, promptly turn OFF the switch.
