Handling instructions

CJ110MV

Note:
Before using this Electric Power Tool, carefully read through these
HANDLING INSTRUCTIONS to ensure efficient, safe operation. It is
recommended that these INSTRUCTIONS be kept readily available
as an important reference when using this power tool.

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.

1

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.

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 JIG SAW

Lever

Blade

Blade holder

This Jig saw employs a high-power motor. 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.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements specified on the product

nameplate.

2. Power switch

Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.

3. Extension cord

When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be kept
as short as practicable.

4. Changing blades

(1) Open the lever up to the stop. (Fig. 1-I)
(2) Remove fitted blade.
(3) Insert new blade up to the stop in the blade holder.

(Fig. 1-II)

(4) Close the lever. (Fig. 1-III)

CAUTION:

䡬 Be sure to switch power OFF and disconnect the plug

from the receptacle when changing blades.

䡬 Do not open the lever when plunger is moving.

5. Adjusting the blade operating speed (Only CJ110MV)

This Jig Saw is equipped with the electric control

circuit which enables stepless speed control. To adjust

the speed, turn the dial shown in Fig. 4. When the dial

is set to “1”, the jig saw operates at the minimum

speed (850min

operates at the maximum speed (3000min

the speed according to the material to be cut and

–1

). When the dial set to “5”, the jig saw

–1

). Adjust

working efficiency.

6. Adjusting the orbital operation

(1) This Jig Saw employs orbital operation which moves

the blade back and forth, as well as up and down. Set
the change knob shown in Fig. 5 to “0” to eliminate
the orbital operation (the blade moves only up and
down). The orbital operation can be selected in 4 steps
from “0” to “III”.

Fig. 5

(2)

For the hard material, such as a steel plate, etc.,
decrease the orbital operation. For the soft material,
such as lumber, plastic, etc., increase the orbital
operation to increase work efficiency. To cut the
material accurately, decrease the orbital operation.

7. Cutting stainless steel plates (Only CJ110MV)

This Jig Saw can cut stainless steel plates by using
No. 97 blade. Carefully read “Concerning cutting of
stainless steel plates” for proper operation.

8. Splinter guard

Using the splinter guard when cutting wood materials
will reduce splintering of cut surfaces.
Insert the splinter guard in the space on the base, and
push it completely. (See Fig. 6)

CAUTION:

At low speed (dial setting: 1 or 2) do not cut a wood

with a thickness of more than 10 mm or metal with a

thickness of more than 1 mm.
