ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Blade inspection
Before using the tool, check the blades for wear. Dull,
worn blades will result in poor shearing action, and the
service life of the tool will be shortened.
The service life of the blades varies in terms of the mate-
rials to be cut and the fixed blade clearance. Roughly
speaking, a blade can cut about 500 m of 3.2 mm mild
steel with one cutting edge (total 2,000 m with four cut-
ting edges).
Rotating or replacing blades
Both the upper and lower blades have four cutting edges
on each side (the front and back). When the cutting edge
becomes dull, rotate both the upper and the lower blades
90° to expose new cutting edges.
When all eight edges are dull on both the upper and
lower blades, replace both blades with new ones. Each
time blades are rotated or replaced, proceed as follows.
Remove the blade securing bolts with the hex wrench
provided and then rotate or replace the blades. (Fig. 3)
Install the upper blade and tighten the upper blade secur-
ing bolt with the hex wrench. Press up on the upper blade
while tightening it. (Fig. 4)
After securing the upper blade, be sure that there is no
gap left between the upper blade and the bevelled sur-
face of the blade holder. (Fig. 5)
Then install the lower blade like the upper blade while
adjusting the clearance between the upper blade and
lower blades. When performing this adjustment, the
upper blade should be in the lowered position. (Fig. 6)
First, semi- tighten the lower blade securing bolt, then
insert the thickness gauge for the desired clearance. The
cutting thickness is indicated on the thickness gauge so
the combinations shown in the table below should be
used. Work the lower blade positioning bolt on the yoke
until the clearance is such that the thickness gauge
moves only with some difficulty. Then firmly tighten the
lower blade securing bolt. Finally, tighten the hex nut to
secure the lower blade positioning bolt. (Fig. 7)

OPERATION

Holding material (Fig. 8)
The materials for cutting should be fastened to the work-
bench by means of workholders.
Shearing method (Fig. 9)
For smooth cuts, tip the tool slightly backward while
advancing it.

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. 11)
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. (Fig. 12)
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.
