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.

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.

APPLICATIONS

(1) Cutting the hard boards types T9 and T7.

(ex. harditex, hardiflex, etc.) (2) Cutting the gypsum board.

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. Prepare a wooden workbench (Fig. 1)

Since the saw blade will extend beyond the lower surface of the lumber, place the lumber on the workbench prior to cutting. If a square block is utilized as the workbench, adjust leveling to ensure that it is properly stabilized. An unstable workbench will result in hazardous operation.

CAUTION

● To avoid possible accident, remains always ensure that the portion of workpiece after cutting is securely anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

1. Adjusting the cutting depth (Fig. 2)

CAUTION

If the clamp lever is loose, injury can result. Tighten it securely after adjustment.

(1) To adjust cutting depth, loosen the clamp lever and,

while holding the base with one hand, move the main body up and down to obtain the prescribed cutting depth. After adjusting to the prescribed cutting depth, tighten the clamp lever securely.

(2) When a base and saw blade are right-angled, it cuts

deeply using the scale of a link part, and the depth can be adjusted (Fig. 3).

English

3. Regulating the guide (Fig. 4)

The cutting position can be regulated by moving the guide to the left or right after loosening its wing-bolt. The guide may be mounted on either the right or left side of the base.

CUTTING PROCEDURES

CAUTION

䡬 During use, when the body is out of condition or there

is unusual sound, please turn off a switch immediately.

䡬 During cutting, please do not pry the body or do not

push too much strongly. Please carry forward the body calmly straightly. It becomes the cause of an injury in response to restitution. Moreover, while unreasonableness starts a motor part, the life of saw blade is shortened.

䡬 Please do not carry out usage which made saw blade

facing up and sideways. It becomes the cause of an injury.

䡬 Please use protection glasses. 䡬 Please use the protection implement of an ear. 䡬 Surely, the time of work discontinuation and after

work should turn off and put a switch, and should pull out a lump plug from a power supply wall socket.

䡬 Be careful by rotating saw blade not to cut a code.

NOTE

䡬 Before beginning cutting, rotation of saw blade should

become the maximum high speed.

䡬 Extrusion fabrication cement building materials

should not cut 1 time of the cut depth with the speed of 40 cm or less in 20 mm or less and 1 minute.

When using the cut depth, making it shallow, in order that edge of a blade may open, dust-collecting power declines.

1. The body (base) is carried on work piece and guide slot of the base front part is united with a premarked line.

When you do not incline, please follow large guide slot as a guide, and when you incline (45°), follow small guide slot as a guide (Fig. 5, Fig. 6, Fig. 7).

2. Saw blade turns on a switch in the state where work piece cannot be touched.

This state is maintained until it carries forward the body ahead slowly and finishes cutting it then. For pulling and cleaning the skin, it advances straightly with fixed speed.

MOUNTING AND DISMOUNTING THE SAW BLADE

As for this body, saw blade is not attached to the body at the time of factory shipments. Please carry out attachment and removal of saw blade in the following procedure in the case of use.

CAUTION

䡬 Surely, please turn off and put a switch in the case of

attachment and removal of saw blade, and pull out a lump plug from a power supply wall socket. It becomes the basis of the unexpected accident.

䡬 Attachment and detachment of a hexagonal flange

bolt should work with an attached box spanner. If tools other than attachment are used, it will become

past [a bundle] and the shortage of bolting, and will become the cause of an injury.

1. How to attach (Fig. 8)

(1) The cut depth is made into the minimum.

A lever is loosened, a base is made into the minimum cut depth, and a lever is fastened.

(2) Two projection parts of a slide cover are pressed

down with a finger, and it moves up (Fig. 9).

(3) A washer (A) is removed (Fig. 10).

Pushing in a lock lever, a hexagonal flange bolt is loosened with an attached box spanner, and a washer (A) is removed. Since a hexagonal flange bolt is a left screw, it will loosen, if it turns clockwise. After removing, the garbage adhering to the spindle or the washer (A) is often wiped off.

(4) Saw blade is attached (Fig. 11)

A lower guard is carried out to full open, and saw blade is attached. It is made in agreement [the direction of an arrow of saw blade] with the direction of an arrow of saw cover.

(5) A hexagonal flange bolt is tightened (Fig. 12).

A washer (A) and a hexagonal flange bolt are attached in order of the left figure, and a hexagonal flange bolt is fully bound tight using an attached box spanner, pushing a lock lever.

USE OF DUST BAG

CAUTION

䡬 To avoid serious accident, ensure the switch is

in the OFF position, and disconnect the plug from the receptacle.

䡬 Never attempt to saw any material like metal and

so on that give off sparks. Such action can lead to fire or injury.

1. Mounting the dust bag

Hold the clasp of the dust bag and insert it into the adapting mouth of the body while opening the thrusting mouth (Fig. 13).

2. Dumping sawdust and cleaning the inside of dust bag

NOTE

䡬 If too much sawdust is accumulated inside the

dust bag, the dust collector will run low on power. Attempt to dump the sawdust as early as you can and clean the dust bag thoroughly so that you can enjoy your work with strong dust collecting power.

(1) Hold the clasp, open the thrusting mouth of the

dust bag, and pull it off from the body.

(2) Open the fastener (Fig. 14) and dump the sawdust.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade

Since use of a dull saw blade will degrade efficiency and cause possible motor malfunction. Resharpen and replace the saw blade as soon as 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.
