b) Use power tools
designated battery packs.
Use of any other battery packs may create a risk of
injury and fi re.
c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another.
Shorting the battery terminals together may cause
burns or a fi re.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
6) Service
a) Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts.
This will ensure that the safety of the power tool is
maintained.
PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of
children and infi rm persons.
CORDLESS JIG SAW SAFETY
WARNINGS
1. Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the
operator an electric shock.
ADDITIONAL SAFETY WARNINGS
1. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
2. Never disassemble the rechargeable battery and
charger.
3. Never short-circuit
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
4. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
5. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
6. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or infl ammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
7. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Therefore,
whenever the housing becomes hot, give the blade a
break for a while.
8. If the machine is used continuously at low speed, an
extra load is applied to the motor which can result in
motor seizure. Always operate the power tool so that
the blade is not caught by the material during operation.
Always adjust the blade speed to enable smooth cutting.
only with specifi cally
the rechargeable battery.
9. Use clamps or another practical way to secure and
support the workpiece to a stable platform.
Holding the work by hand or against your body leaves it
unstable and may lead to loss of control.
10. Preparing and checking the work environment. Make
sure that the work site meets all the conditions laid forth
in the precautions.
11. Make sure that the battery is installed fi rmly. If it is at all
loose it could come off and cause an accident.
12. Dust produced in operation
The dust produced in normal operation may aff ect
the operator's health. Either of following way is
recommended.
a) Wear a dust mask
b) Use external dust collection equipment
(optional accessories) (Fig. 2)
When using the external dust collection equipment,
connect the adapter with the hose from external dust
collection equipment.
13. Changing blades
○ Be sure to switch power OFF and disconnect the battery
from the body when changing blades.
○ Do not open the lever when plunger is moving. (Fig. 3, 4)
○ Confi rm the protrusions of blade inserted to the blade
holder surely. (Fig. 3)
○ Confi rm the blade located between the groove of roller.
(Fig. 3)
14. Chip cover
○ Chip cover prevents chips from fl ying off and improves
the effi ciency of dust collector.
○ There is a possibility that chip cover is frosted when
cutting the metal.
15. In order to prevent blade dislodging, damage or
excessive wear on the plunger, please make sure to
have surface of the base plate attached to the work piece
while sawing.
16. At low speed do not cut a wood with a thickness of more
than 10 mm or metal with a thickness of more than 1 mm.
17. When sawing a small circular arc, reduce the feeding
speed of the machine. If the machine is fed too fast, it
could cause the blade to break.
18. Circular cutting must be done with the blade
approximately vertical to the bottom surface of the base.
19. When cutting metallic materials, use an appropriate
cutting fl uid (spindle oil, soapy water, etc.) to prolong
the bladeʼs service life. (Fig. 5) And cut the material at
medium speed.
20. When cutting a window hole in materials other than
lumber, initially bore a hole with a drill or similar tool from
which to start cutting. (Fig. 7)
21. Do not fi x and secure the switch lock. Besides, keep
your fi nger off the switch trigger when the jig saw is
being carried around. Otherwise, the main body switch
can be inadvertently turned ON, resulting in unexpected
accidents.
22. Keep the light ON during cutting operation only. If
it is lit ON in other cases, the main body switch can
be inadvertently turned ON, resulting in unexpected
accidents.
23. Do not expose directly your eye to the light by looking
into the light.
If your eye is continuously exposed to the light, your eye
will be hurt.
24. Never touch moving parts.
Never place your hands, fi ngers or other body parts near
the tool's moving parts.
