Carrying power tools with your ﬁ nger on the switch

or energising power tools that have the switch on

invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

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 dust collection 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 and/

or the battery pack from the power tool 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 aﬀ ect the

power toolʼs 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,

taking into account the working conditions and

the work to be performed.

Use of the power tool for operations diﬀ erent from

those intended could result in a hazardous situation.

5) Battery tool use and care

a) Recharge only with the charger speciﬁ ed by the

manufacturer.

A charger that is suitable for one type of battery pack

battery pack.

b) Use power tools only with speciﬁ cally

designated battery packs.

Use of any other battery packs may create a risk of

injury and ﬁ re.

GENERAL POWER TOOL SAFETY

WARNINGS

WARNING

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in

electric shock, ﬁ re and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-

operated (corded) power tool or battery-operated (cordless)

power tool.

1) Work area safety

a) Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of

ﬂ ammable liquids, gases or dust.

Power tools create sparks which may ignite the dust

or 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.

Unmodiﬁ ed 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.

f) If operating a power tool in a damp location

is unavoidable, use a residual current device

(RCD) protected supply.

Use of an RCD 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 inﬂ uence of drugs, alcohol or

medication.

A moment of inattention while operating power tools

may result in serious personal injury.

b) Use personal protective equipment. Always

wear eye protection.

Protective equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used for

appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the

switch is in the oﬀ position before connecting to

power source and/or battery pack, picking up or

carrying the tool.

(Original instructions)

English

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 RECIPROCATING 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. Preparing and checking the work environment. Make

sure that the work site meets all the conditions laid forth

in the precautions.

2. Do not allow foreign matter to enter the hole for

connecting the rechargeable battery.

3. Never disassemble the rechargeable battery and

charger.

4. Never short-circuit the rechargeable battery.

Shortcircuiting the battery will cause a great electric

current and overheat. It results in burn or damage to the

battery.

5. Do not dispose of the battery in ﬁ re. If the battery is burnt,

it may explode.

6. 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.

7. 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.

8. 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 saw a

break for a while.

9. 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.

10. Always hold the body handle and front cover of the

power tool ﬁ rmly. Otherwise the counterforce produced

may result in inaccurate and even dangerous operation.

11. Mounting and dismounting the blade

○ Pull the back of the saw blade two or three times by hand

and check that the blade is securely mounted. When

pulling the blade, you will know it is properly mounted if it

clicks and the lever moves slightly. (Fig. 2)

○ When pulling the saw blade, be absolutely sure to pull it

from the back. Pulling other parts of the blade will result

in an injury.

○ If the broken saw blade is hidden inside the small slit,

hook the broken blade using a tip of another saw blade

and take it out. (Fig. 3)

○ After use, blow away sawdust, earth, sand, moisture,

etc., with air or brush them away with a brush, etc., to

ensure that the blade mount can function smoothly.

○ Do not use any saw blade with a worn-out blade hole.

Otherwise, the saw blade can come oﬀ , resulting in

personal injury.

12. Make sure that the battery is installed ﬁ rmly. If it is at all

loose it could come oﬀ and cause an accident.

13. Do not ﬁ x and secure the switch lock. Besides, keep

your ﬁ nger oﬀ the switch trigger when the circular saw is

being carried around. Otherwise, the main body switch

can be inadvertently turned ON, resulting in unexpected

accidents.

14. Be careful not to let sawdust, earth, moisture, etc., enter

the inside of the machine through the plunger section

during operation. If sawdust and the like accumulate in

the plunger section, always clean it before use.

15. Do not remove the front cover which will cause in an

injury.

Be sure to hold the body from the top of the front cover.

16. During use, press the base ﬁ rmly against the workpiece.

17. Select a saw blade of the most appropriate length.

Ideally, the length protruding from the base of the saw

blade after su

btracting the stroke quantity should be

larger than the material.

If you cut a large pipe, large block of wood, etc., that

exceeds the cutting capacity of a blade; there is a risk

that the blade may contact with the inner wall of the pipe,

wood, etc., resulting in damage. (Fig. 4)

18. Never apply any unreasonable force to the saw blade

when cutting. Doing so can easily break the blade.

19. The motor can be locked sometimes, depending

on the combination of the material to be cut and the

blade. Whenever the motor gets locked, switch it oﬀ

immediately.

20. Use clamps or another practical way to secure and

support the workpiece to a stable platform. (Fig. 5)

Holding the work by hand or against your body leaves it

unstable and may lead to loss of control.

21. When cutting metallic materials, use an appropriate

cutting ﬂ uid (spindle oil, soapy water, etc.) to prolong the

bladeʼs service life.

22. Delay the feed speed when cutting the material into

small circular arcs. An unreasonably fast feed may break

the blade.

23. Plunge cutting

○ Avoid plunge cutting for metallic materials. This can

easily damage the blade.

○ Never pull the switch trigger while the tip of the saw

blade tip is pressed against the material. If you do so, the

blade can easily be damaged when it collides with the

material.

○ Make absolutely sure that you cut slowly while holding

the body ﬁ rmly. If you apply any unreasonable force to

the saw blade during the cutting operation, the blade can

easily be damaged.

24. 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.

English

25. 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.

26. Never touch moving parts.

Never place your hands, ﬁ ngers or other body parts near

the tool’s moving parts.

27. Never operate without all guards in place.

Never operate this tool without all guards or safety

features in place and in proper working order. If

maintenance or servicing requires the removal of a

guard or safety feature, be sure to replace the guard or

safety feature before resuming operation of the tool.

28. NEVER leave tool running unattended. Turn power oﬀ .

Don’t leave tool until it comes to a complete stop.

MAINTENANCE AND INSPECTION

CAUTION

Be sure to turned oﬀ the switch and remove the battery

before maintenance and inspection.

1. Inspecting the blade

Continued use of a dull or damaged blade will result in

reduced cutting eﬃ ciency and may cause overloading of

the motor. Replace the blade with a new one as soon as

excessive abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the screws be

loose, retighten them immediately. Failure to do so could

result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very “heart” of the power

tool. Exercise due care to ensure the winding does not

become damaged and/or wet with oil or water.

4. Cleaning on the outside

When the power tool is stained, wipe with a soft dry cloth

or a cloth moistened with soapy water. Do not use chloric

solvents, gasoline or paint thinner, for they melt plastics.

5. Storage

Store the power tool in a place in which the temperature

is less than 40°C and out of reach of children.

NOTE

Storing lithium-ion batteries.

Make sure the lithium-ion batteries have been fully

charged before storing them.

Prolonged storage (3 months or more) of batteries with

a low charge may result in performance deterioration,

signiﬁ cantly reducing battery usage time or rendering

the batteries incapable of holding a charge.

However, signiﬁ cantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to ﬁ ve times.

If the battery usage time is extremely short despite

repeated charging and use, consider the batteries dead

and purchase new batteries.
