Permissible cutting thickness (Fig. 4)
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. 5)
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 oper-
ator 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. 6)
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. 7,
8, 9 & 10)
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. 11)
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. 12)
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. 13 & 14)
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. 15, 16 & 17)
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
using Makita replacement parts.
