FUNCTIONAL DESCRIPTION

CAUTION:

- Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge (Fig. 1)

CAUTION:

• Always switch off the tool before installing or removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury.

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.

To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

CAUTION:

• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
- Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system (Fig. 2)

The tool is equipped with a battery protection system. This system automatically cuts off power to the motor to extend battery life.

The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

• Overloaded:

The tool is operated in a manner that causes it to draw an abnormally high current.

In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart.

If the tool does not start, the battery is overheated. In this situation, let the battery cool before turning the tool on again.

- Low battery voltage:

The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery.

NOTE:

- The overheat protection works only with a battery cartridge with a star mark.

Indicating the remaining battery capacity (Fig. 3) Only for battery cartridges with the indicator

Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for few seconds.

Indicator lamps			Remaining Capacity
Lighted Off Blinking
			75% to 100%
			50% to 75%
			25% to 50%
			0% to 25%
			Charge the battery.
			The battery may have malfunctioned.

015658

NOTE:

- Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

Changing the die position (Fig. 4)

The die holder position can be changed 360°. To change it, proceed as follows.

1. Loosen the lock nut with the wrench provided.
2. Pull the die holder slightly and turn it to the desired position for operation.
3. Tighten the lock nut to secure the die holder in the desired position.

There are four positive stops at 90^ each: 0^ , 90^ left and right and 180^ . To position the die to any of these positive stops:

1. Loosen the lock nut with the wrench provided.

2. Pull the die holder slightly and depress lightly while turning it to the desired position. The die holder will lock into one of the positive stop positions as desired.

3. Turn the die holder slightly to make sure that it is positively locked into position.

4. Tighten the lock nut to secure the die holder.

Permissible cutting thickness (Fig. 5)

The thickness of material to be cut depends upon the tensile strength of the material itself. The groove on the die holder acts as a thickness gauge for allowable cutting thickness. Do not attempt to cut any material which will not fit into this groove.

Cutting line

The notch in the die holder indicates your cutting line. Its width is equal to the cutting width. Align the notch to the cutting line on the workpiece when cutting.

Switch action (Fig. 6)

CAUTION:

• Before inserting the battery cartridge into the tool, always check to see that the slide switch actuates properly and returns to the "OFF" position when the rear of the slide switch is depressed.
• Switch can be locked in "ON" position for ease of operator comfort during extended use. Apply caution when locking tool in "ON" position and maintain firm grasp on tool.

To start the tool, slide the slide switch toward the "I (ON)" position. For continuous operation, press the front of the slide switch to lock it.

To stop the tool, press the rear of the slide switch, then slide it toward the "O (OFF)" position.

Indication lamp with multi function (Fig. 7)

Indication lamps are located in two positions.

- Battery cartridge replacing signal

- When the battery power is almost used up during operation, the red lamp lights up and the tool stops immediately. Replace the battery with fully charged one when the red lamp lights up.

- Accidental re-start preventive function

- Even if the battery cartridge is inserted on the tool with the slide switch in the "I (ON)" position, the tool does not start. At this time, the lamp flickers slowly and this shows that the accidental re-start preventive function is at work.

- To start the tool, first slide the slide switch toward the "O (OFF)" position and then slide it toward the "I (ON)" position.

ASSEMBLY

CAUTION:

- Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Removing or installing the punch and die (Fig. 8, 9, 10 & 11)

Always replace the punch and die as a set. To remove the punch and die, loosen the lock nut with the wrench. Remove the die holder from the tool. Use the hex wrench to loosen the bolts which secure the die. Remove the die from the die holder.

Use the hex wrench to loosen the screw which secures the punch. Pull the punch out of the punch holder.

To install the punch and die, insert the punch into the punch holder so that the notch in the punch faces toward the screw. Tighten the screw to secure the punch. Install the die on the die holder. Tighten the bolts to secure the die.

Then install the die holder on the tool so that the punch is inserted through the hole in the die holder. Tighten the lock nut to secure the die holder. After replacing the punch and die, lubricate them with machine oil and run the tool for a while.

OPERATION

Pre-lubrication

Coat the cutting line with machine oil to increase the punch and die service life. This is particularly important when cutting aluminum.

Cutting method (Fig. 12)

Hold the tool so that the cutting head is at a right angle (90°) to the workpiece being cut. Move the tool gently in the cutting direction.

Cutouts (Fig. 13)

Cutouts can be done by first opening a round hole over 21 mm in diameter which the cutting head can be inserted into.

Cutting the corrugated or trapezoidal sheet metals (Fig. 14 & 15)

Set the die position so that the die faces the cutting direction either when cutting at an angle or perpendicular go grooves in corrugated or trapezoidal sheet metals.

Always hold the tool body parallel to the grooves with the cutting head at a right angle (90°) to the cutting surface as shown in the figure.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

Replacing carbon brushes (Fig. 16, 17 & 18)
