Permissible cutting thickness (Fig. 2)
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. 3)
CAUTION:
• Before plugging in the tool, always check to see that
the switch actuates properly and returns to the "OFF"
position when the rear of the switch lever is depressed.
To switch on, depress the rear of the switch lever and
push it forward. Then depress the front of the switch lever
to lock it.
To switch off, depress the rear of the switch lever.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Removing or installing the punch and die
(Fig. 4, 5, 6 & 7)
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. 8)
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. 9)
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. 10 & 11)
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 Fig. 10 & 11.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged 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. 12 & 13)
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.
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.
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.
