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: 1. From the top view 2. Cutting at an

5. Corrugated or trapezoidal sheet metal
Set the die position so that the die faces the cutting
direction either when cutting at an angle or perpen-
dicular 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.
► Fig.11: 1. From the side view 2. Cutting head
should be at a right angle (90°) to cutting

MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
Replacing carbon brushes

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.
