c) Use power tools only with specifically designated
battery packs.
Use of any other battery packs may create a risk
of injury and fire.
d) 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 fire.
e) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush 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 qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
PRECAUTIONS ON USING CORDLESS
RECIPROCATING SAW
1.
Always charge the battery at a temperature of 10 –
40°C. A temperature of less than 10°C will result in
over charging which is dangerous. The battery cannot
be charged at a temperature higher than 40°C.
The most suitable temperature for charging is that
of 20 – 25°C.
2.
Do not use the charger continuously.
When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
3.
Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
4.
Never disassemble the rechargeable battery and
charger.
5.
Never short-circuit the rechargeable battery. Short-
circuiting the battery will cause a great electric
current and overheat. It results in burn or damage
to the battery.
6.
Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
7.
When using this unit continuously, the unit may
overheat, leading to damage in the motor and
switch. Please leave it without using it for
approximately 15 minutes.
8.
Do not insert object into the air ventilation slots
of the charger.
Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
9.
Using an exhausted battery will damage the charger.
10. Prior to cutting into walls, ceillings or floors, ensure
there are no electric cables or conduits inside.
11. 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.
12. Wear earplugs to protect your ears during operation.
13. Do not touch the blade during or immediately
after operation. The blade becomes very hot during
operation and could cause serious burns.
14. Always hold the body handle and front cover of
the power tool firmly. Otherwise the counterforce
produced may result in inaccurate and even
dangerous operation.
15. Remove the battery from tool or place the switch in
the locked or off position before making any
adjustments, changing accessories, or storing the tools.

CAUTION ON LITHIUM-ION BATTERY

To extend the lifetime, the lithium-ion battery equips
with the protection function to stop the output.
In the cases of 1 and 2 described below, when using
this product, even if you are pulling the switch, the
motor may stop. This is not the trouble but the result
of protection function.
1. When the battery power remaining runs out (The
battery voltage drops to about 12V (CR18DL)), the
motor stops.
In such case, charge it up immediately.
2. If the tool is overloaded, the motor may stop. In this
case, release the switch of tool and eliminate causes
of overloading. After that, you can use it again.
Furthermore, please heed the following warning and
caution.
WARNING
In order to prevent any battery leakage, heat generation,
smoke emission, explosion and ignition beforehand,
please be sure to heed the following precautions.
1. Make sure that swarf and dust do not collect on
the battery.
During work make sure that swarf and dust do not
fall on the battery.
Make sure that any swarf and dust falling on the
power tool during work do not collect on the battery.
Do not store an unused battery in a location exposed
to swarf and dust.
Before storing a battery, remove any swarf and dust
that may adhere to it and do not store it together
with metal parts (screws, nails, etc.).
2. Do not pierce battery with a sharp object such as
a nail, strike with a hammer, step on, throw or
subject the battery to severe physical shock.
3. Do not use an apparently damaged or deformed
battery.
4. Do not use the battery in reverse polarity.
5. Do not connect directly to an electrical outlets or
car cigarette lighter sockets.
6. Do not use the battery for a purpose other than
those specified.
7. If the battery charging fails to complete even when
a specified recharging time has elapsed, immediately
stop further recharging.
8. Do not put or subject the battery to high
temperatures or high pressure such as into a
microwave oven, dryer, or high pressure container.
9. Keep away from fire immediately when leakage or
foul odor are detected.
10. Do not use in a location where strong static electricity
generates.
11. If there is battery leakage, foul odor, heat generated,
discolored or deformed, or in any way appears abnormal
during use, recharging or storage, immediately remove
it from the equipment or battery charger, and stop use.
