Indication lamp with multi function (Fig. 5)

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 bat-

tery cartridge is removed before carrying out any work

on the tool.

Removing or installing the punch and die (Fig. 6,

7, 8 & 9)

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. 10)

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. 11)

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. 12 & 13)

Set the die position so that the die faces the cutting direc-

tion 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 bat-

tery 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. 14, 15 & 16)

Remove and check the carbon brushes regularly.

Replace when they wear down to the limit mark. Keep

the carbon brushes clean and free to slip in the holders.

Both carbon brushes should be replaced at the same

time. Use only identical carbon brushes.

Insert the top end of slotted bit screwdriver into the notch

in the tool and remove the holder cap cover by lifting it

up.

Use a screwdriver to remove the brush holder caps. Take

out the worn carbon brushes, insert the new ones and

secure the brush holder caps.

Reinstall the holder cap cover on the tool.

To maintain product SAFETY and RELIABILITY, repairs,

any other maintenance or adjustment should be per-

formed by Makita Authorized Service Centers, always
