Cutting aluminum extrusion (Fig. 19)
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in Fig. 19 to
prevent deformation of the aluminum. Use a cutting
lubricant when cutting the aluminum extrusion to
prevent build-up of the aluminum material on the
blade.
CAUTION:
Never attempt to cut thick or round aluminum extru-
sions. Thick aluminum extrusions may come loose
during operation and round aluminum extrusions can-
not be secured firmly with this machine.
Adjusting for smooth handle action (Fig. 20)
The hex lock nut holding together the blade case and
arm has been factory adjusted to assure smooth
handle action up and down and to guarantee precise
cutting. Do not tamper with it.
Should looseness develop at the blade case and arm
connection, tighten the hex lock nut using a wrench
while holding the bolt with another wrench.
After adjusting the hex lock nut, be sure the handle
returns automatically to the initial, raised position from
any position. If the hex lock nut is too loose, the
cutting accuracy will be affected; if it is too tight, it will
be hard to work the handle up and down. Note that
this is a self locking nut; it is a special type that does
not loosen during normal use. It should not be over-
tightened or replaced with other types of nuts.
Alignment for squareness (Fig. 21 & 22)
This machine was carefully adjusted and aligned for
squareness of cut at the factory, but rough handling
may have affected the alignment. If your machine is
not aligned properly, perform the following.
Loosen the grip and set the turn base at zero degrees
by turning the turn base. Tighten the grip securely and
loosen the hex bolts on the guide fence. Square the
side of the blade with the face of the guide fence using
a triangular rule, try-square, etc. by moving the right
side of the guide fence. Then securely tighten the hex
bolts on the guide fence in the order indicated in
Fig. 22.
Installing holders and set plates
(optional accessories) (Fig. 23)
The holders can be installed on either side as a
convenient means of holding workpieces horizontally
or workpieces to be cut repetitively into identical
lengths. To install the holder, insert the holder through
the hole in the set plate with the curved portion of the
holder pointing upwards. Then slip the holder rods
into the holes in the base. Tighten the holders
securely with wing bolts.
Cutting repetitive lengths
When cutting several pieces of stock to the same
length, ranging between 235 – 400 mm, use of the set
plate will facilitate more efficient operation. Align the
cutting line on your workpiece with either the left or
right side of the groove in the kerf board, and while
holding the workpiece form moving, move the set
plate flush against the end of the workpiece. Then
secure the set plate with the wing bolt on the set plate.
Carrying machine (Fig. 15 & 24)
When carrying the machine, lower the handle fully
and press the stopper pin to lock the handle in the
lowered position. Secure the turn base by means of
the grip. The machine can then be conveniently
carried by the carrying grip.
WARNING:
Be sure that the machine is unplugged first.
MAINTENANCE
CAUTION:
Always be sure that the machine is switched off and
unplugged before carrying out any work on the
machine.
Replacement of carbon brushes (Fig. 25 & 26)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
Makita Authorized Service Center.
