Cutting repetitive lengths
► Fig.29: 1. Set plate 2. Holder 3. Screw
When cutting several pieces of stock to the same
length, ranging from 300 mm to 400 mm, use of
the set plate (optional accessory) will facilitate
more efficient operation. Install the set plate on the
holder (optional accessory) as shown in the figure.
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 from moving,
move the set plate flush against the end of the
workpiece. Then secure the set plate with the screw. When the set plate is not used, loosen the
screw and turn the set plate out of the way.
NOTE:
• Use of the holder-rod assembly (optional acces-
sory) allows cutting repetitive lengths up to
2,200 mm approximately.
Carrying tool
► Fig.30: 1. Handle latch
Make sure that the tool is unplugged. Secure the turn
base at right miter angle fully by means of the grip.
Lower the handle fully and lock it in the lowered position
by turning the handle latch to the locked position.
Carry the tool by holding both sides of the tool base
as shown in the figure. If you remove the holders, dust
bag, etc., you can carry the tool more easily.
► Fig.31
CAUTION:
• Always secure all moving portions before carry-
ing the tool.
• Handle latch is for carrying and storage pur-
poses only and not for any cutting operations.
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.
WARNING:
• Always be sure that the blade is sharp and clean
for the best and safest performance.
Adjusting the cutting angle
This tool is carefully adjusted and aligned at the factory,
but rough handling may have affected the alignment. If
your tool is not aligned properly, perform the following:
► Fig.32: 1. Hex bolt
Loosen the grip which secures the turn base. Turn
the turn base so that the pointer points to 0° on the
miter scale. Then turn the turn base slightly clock-
wise and counterclockwise to seat the turn base
in the 0° miter notch. (Leave as it is if the pointer
does not point to 0°.) Loosen the hex bolts secur-
ing the guide fence using the socket wrench.
Lower the handle fully and lock it in the lowered
position by turning the handle latch to the locked
position. Square the side of the blade with the face
of the guide fence using a triangular rule, try-
square, etc. Then securely tighten the hex bolts on
the guide fence in the order from the right side.
► Fig.33: 1. Guide fence 2. Triangular rule
Make sure that the pointer on the indication plate
points to 0° on the miter scale. If the pointer does
not point to 0°, loosen the screws which secure
the indication plate and adjust it so that the pointer
will point to 0°.

Adjusting for smooth handle action
► Fig.35: 1. Gear housing 2. Hex lock nut 3. Arm
The hex lock nut which holds the gear housing and the
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
gear housing and arm connection, perform the follow-
ing adjustment. Work the handle up and down while
tightening the hex lock nut; the best position to tighten
the hex lock nut is just before the motor body weight is
obvious.
After adjusting the hex lock nut, be sure that 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 in
normal use. It should not be overtightened or replaced
with other types of nuts.
Replacing carbon brushes
► Fig.36: 1. Limit mark
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.
