IMPORTANT SAFETY INFORMATION

Read and understand all of the safety precautions, warnings and operating instructions in

the Instruction Manual before operating or maintaining this power tool.

Most accidents that result from power tool operation and maintenance are caused by the

failure to observe basic safety rules or precautions. An accident can often be avoided by

recognizing a potentially hazardous situation before it occurs, and by observing appropriate

safety procedures.

Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual

and in the sections which contain the operation and maintenance instructions.

Hazards that must be avoided to prevent bodily injury or machine damage are identified by

WARNINGS on the power tool and in this Instruction Manual.

NEVER use this power tool in a manner that has not been specifically recommended by

HITACHI.

MEANINGS OF SIGNAL WORDS

SAFETY

GENERAL SAFETY RULES

WARNING: Read and understand all instructions.

Failure to follow all instructions listed below, may result in electric shock,

fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

1. Work Area

(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

(2) 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.

(3) Keep bystanders children, and visitors away while operating a power tool.

Distractions can cause you to lose control.

2. Electrical Safety

(1) Double Insulated tools are equipped with a polarized plug (one blade is wider than

the other). This plug will fit in a polarized outlet only one way. If the plug does not

fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified

electrician to install a polarized outlet. Do not change the plug in any way. Double

Insulation

eliminates the need for the three wire grounded power cord and

grounded power supply system.

(2) Avoid body contact with grounded surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is grounded.

(3) Do not expose power tools to rain or wet conditions. Water entering a power tool

will increase the risk of electric shock.

(4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from

a receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace

damaged cords immediately. Damaged cords increase the risk of electric shock.

(5) When operating a power tool outside, use an outdoor extension cord marked “W-

A” or “W”. These cords are rated for outdoor use and reduce the risk of electric

shock.

3. Personal Safety

(1) Stay alert, watch what you are doing and use common sense when operating a

power tool. Do not use tool while tired or under the influence of drugs, alcohol, or

medication. A moment of inattention while operating power tools may result in

serious personal injury.

(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep

your hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or

long hair can be caught in moving parts.

5

English

(3) Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools

with your finger on the switch or plugging in tools that have the switch on invites

accidents.

(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key

that is left attached to a rotating part of the tool may result in personal injury.

(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enables better control of the tool in unexpected situations.

(6) Use safety equipment. Always wear protective glasses. Dust mask, nonskid safety

shoes, hard hat, or ear plugs must be used for appropriate conditions.

4. Tool Use and Care

(1) Use clamps or other practical way to secure and support the workpiece to a stable

platform. Holding the work by hand or against your body is unstable and may lead

to loss of control.

(2) Do not force tool. Use the correct tool for your application. The correct tool will do

the job better and safer at the rate for which it is designed.

(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled

with the switch is dangerous and must be repaired.

(4) Disconnect the plug form the power source before making any adjustments,

changing accessories, or storing the tool. Such preventive safety measures reduce

the risk of starting the tool accidentally.

(5) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

(6) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained

tools, with sharp cutting edges are less likely to bind and are easier to control.

(7) Check for misalignment or binding of moving parts, breakage of parts, and any

other condition that may affect the tool's operation. If damaged, have the tool

serviced by a HITACHI authorized service center before using. Many accidents are

caused by poorly maintained tools.

(8) Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool, may become hazardous when used

with another tool.

5. Service

(1) Tool service must be performed only by a HITACHI authorized service center. Service

or maintenance performed by unqualified personnel could result in a risk of injury.

(2) When servicing a tool, use only identical replacement parts. Follow instructions in

the Maintenance section of this manual. Use of unauthorized parts or failure to

follow Maintenance Instruction may create a risk of electric shock or injury.

DOUBLE INSULATION FOR SAFER OPERATION

To ensure safer operation of this power tool, HITACHI has adopted a double insulation

design. “Double insulation” means that two physically separated insulation systems have

been used to insulate the electrically conductive materials connected to the power supply

from the outer frame handled by the operator. Therefore, either the symbol “

” or the

words “Double insulation” appear on the power tool or on the nameplate.

Although this system has no external grounding, you must still follow the normal electrical

safety precautions given in this Instruction Manual, including not using the power tool in

wet environments.

To keep the double insulation system effective, follow these precautions:

䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this

power tool, and only genuine HITACHI replacement parts should be installed.

䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water,

and dry thoroughly.

Never use solvents, gasoline or thinners on plastic components; otherwise the plastic

may dissolve.

CUTTING

CAUTIONS:

䢇 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.

1. Rectilinear cutting

When cutting on a straight line, first draw a

marking gauge line and advance the saw along

that line. Using the guide (sold separately) will

make it possible to cut accurately on a straight

line.

(1) Loosen the base bolt allen wrench attached on

base. (Fig. 11)

(2) Move the base fully forward (Fig. 12), and

tighten the base bolt again.

(3) Attach the guide by passing it through the

attachment hole on the base and tighten the

M5 bolt. (Fig. 13)

(4) Set the orbital position to “0”.

NOTE: To ensure accurate cutting when using the

Guide (Fig.11), always set the orbital

position to “0”.

2. Sawing curved lines

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.

3. Cutting a circle or a circular arc

The guide also will be helpful for circular

cutting.

After attaching the guide by same way noted

as above, drive the nail or screw into the

material through the hole on the guide, then

use it for a axis when cutting. (Fig. 14)

NOTE: Circular cutting must be done with the

blade approximately vertical to the bottom

surface of the base.

4. Cutting metallic materials

(1) Adjust the speed Dial between scales “3” and

“4”.

(2) Set the orbital position to “0” or “I”.

(3) Always use an appropriate cutting fluid

(spindle oil, soapy water, etc.). When a liquid

cutting fluid is not avaiable, apply grease to

the back surface of the material to be cut.

5. Pocket cutting

(1) In lumber

Aligning the blade direction with the grain of

the wood, cut step by step until a window hole

is cut in the center of the lumber. (Fig. 15)

(2) In other materials

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.

6. Angular cutting

The base can be swiveled to both sides by up

to 45° for angular cutting. (Fig. 16)

(1) Loosen the base bolt by allen wrench attached

on base and move the base fully forward. (Fig.

11, 12)

(2) Align the scale (from 0 degrees to 45 degrees

by 15-degree increments) of the semi-circular

part of the base with the [

] mark on the gear

cover. (Fig. 17)

(3) Tighten the M5 bolt again. (Fig. 11)

(4) Set the orbital position to “0”.

NOTE: Angular cutting can not be done when

adopting chip cover or dust collector.

CONCERNING CUTTING OF STAINLESS STEEL PLATES

When used with the No. 97 blade, can cut stainless steel plates.

Note the following to adjus the unit.

CAUTION:

䢇 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.

English

When cutting stainless steel plates, adjust the unit as described below:

1. Adjust the speed

NOTE: Dial scale reading is for reference only. The higher the speed is, the quicker the

material is cut. But the service life of the blade will be reduced in this case. When

the speed is too low, cutting will take longer, although the service life will be

prolonged. Make adjustments as desired.

2. Set the orbital position to “0”

NOTE: When cutting use cutting fluid (oil base cutting fluid) to prolong the blade’s

service life.

SELECTION OF BLADES

䡬 Accessory blades

To ensure maximum operating efficiency and results, it is very important to select the

appropriate blade best suited to the type and thickness of the material to be cut. Three

types of blades are provided as standard accessories. The blade number is engraved in

the vicinity of the mounting portion of each blade. Select appropriate blades by referring

to Table 1 (page 18).
