CONTENTS English Page Page

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

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury. CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate injury, or may cause machine damage. NOTE emphasizes essential information.English

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) 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.

(1) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tires 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. (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.English

(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 eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection 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 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.

(1) Tool service must be performed only by qualified repair personnel. 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.English

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.

FUNCTIONAL DESCRIPTION NOTE: The information contained in this Instruction Manual is designed to assist you in the safe operation and maintenance of the power tool. NEVER operate, or attempt any maintenance on the tool unless you have first read and understood all safey instructions contained in this manual. Some illustrations in this Instruction Manual may show details or attachments that differ from those on your own power tool.

APPLICATIONS 䡬 Cutting and pocket cutting mild steel, stainless steel, copper and aluminium plates corrugated plates and trapezoidal plates.

Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate.

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

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

Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Confirming condition of the environment

Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.English

Inspect for looseness of the M8 hexagon socket set screw used for mounting the die holder, the M3 machine screws used for mounting the die (see Fig. 4) and the M5 hexagon socket set screws used for mounting the punch (see Fig. 8). Caution should be exercised because, if any of these screws are loose, not only does cutting performance deteriorate but the machine can also be damaged.

Before use, carefully lubricate the sliding surfaces around the die and punch (see Fig.

1) with a suitable amount of machine oil or spindle oil.

CAUTION: ● Never try to cut materials that are too large for the capacity of the machine since this may cause damage. ● Applying cutting oil (spindle oil, machine oil, and so on) along the shearing line may decrease wear of the punch and die. Use care to prevent cutting oil adhering to the housing since the surface may be damaged.

As shown in Fig. 2, hold the plates being cut parallel with the machine and apply a light force while cutting. When pocket cutting, make a hole 29/32" (23 mm) in diameter or larger, as shown in Fig. 3, and start cutting with the tip of the die holder. Fig. 2 Fig. 3

2. Cutting corrugated and trapezoidal

plates (1) The cutting direction of this machine can be rotated in 90° increments in 3 directions (A, B and C) (see Fig. 4) by loosening the M8 hexagon socket set screw mounting the die holder. Set the cutting direction in the B or C direction to cut trapezoidal plates. After that, securely tighten the M8 hexagon socket set screw. Fig. 4 Cutting Material Machine Screw

(2) Grip the machine firmly with both hands as shown in Fig. 5, align with the shape of the trapezoidal plate, push the machine forward until the die holder is at right angles as shown in Fig. 6 and make the cut. Fig. 5 Fig. 6 HOW TO REPLACE THE PUNCH AND DIE CAUTION: In this case, be sure to previously disconnect the plug from the power supply.

1. Service life of the punch and die

Wear and damage to the cutting edges of the punch and die can greatly influence the cutting operation. Under normal usage, the service life of the punch and die is as shown in the table below. Replace the punch and die promptly when the end of the service life approaches. The punch and die should be replaced at the same time. When the machine is used according to the service life indicated in the above table, the punch will have abrasions as shown in the enlarged diagram of the worn punch tip in Fig. 7. This is when the punch and die should be replaced. Fig. 7 Die Holder Cutting Material Cutting materials Service life cutting lengths of punch and die 1/16" (1.6 mm) mild steel plates 1000 ft (300 m) 1/16" (1.6 mm) mild steel corrugated and 160 ft (50 m) trapezoidal plates 3/64" (1.2 mm) stainless steel plates 650 ft (200 m) Cutting Edge of Punch Wear due to abrasion 0.01" (0.3 mm)English

Fig. 9 CAUTION: If the punch and die are used longer than the specified service life, the die holder will be subject to excessive stress and may break off. When a 1/16" (1.6 mm) mild steel trapezoidal plate is cut, wear will be especially quick. Replace the punch and die as soon as possible after reaching the service life.

2. Punch and die replacement (see Fig. 8)

CAUTION: During the following operations, use care to prevent dirt adhering inside the gear cover, inside the die holder and around the piston. (1) Punch replacement (a) Loosen the M8 hexagon socket set screw mounting the die holder (see Fig. 4) and remove the die holder. (b) Loosen the M5 hexagon socket set screw fastening the punch to the piston and pull out the punch. (c) Insert the new punch while aligning the taper hole of the punch and the direction of the M5 hexagon socket set screw, then securely tighten the hexagon socket set screw (see Fig. 9). (2) Die replacement Loosen the 2 machine screws and replace the die. (3) Lubrication When the above replacement operations are completed, apply a suitable amount of machine oil to the sliding surfaces around the punch and die and operate the machine without a load.

WARNING: Be sure to switch power OFF and disconnect the plug from the

receptacle during maintenance and inspection.

1. Checking punch and die

A worn or defective punch and die will greatly decrease work efficiency. Check and replace them periodically. Refer to “HOW TO REPLACE THE PUNCH AND DIE”.

2. Inspecting the screws

Regularly inspect all screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately.

WARNING: Using this Nibbler with loosen screws is extremely dangerous.

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. Inspecting the carbon brushes (Fig. 10)

The motor employs carbon brushes which are consumable parts. When they become worn to or near “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Nos. shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders. CAUTION: Using this Nibbler with a carbon brush which is worn in excess of the wear limit will damage the motor. Fig. 10 NOTE: Use HITACHI carbon brush No. 21 indicated in Fig. 10.English

䡬 Replacing carbon brushes Disassemble the brush cap with a screwdriver. The carbon brush can then be easily removed.

5. Service and repairs

All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY.
