PLANING PROCEDURES
1. Adjusting the cutting depth:
(1) Turn the knob in the direction indicated by the
arrow in Fig. 7 (clockwise), until the triangular mark
is aligned with the desired cutting depth on the
scale. The scale unit is graduated in millimeters.
(2) The cutting depth can be adjusted within a range
of 0 – 0.5 mm.
2. Operation of switch
(1) For safe operation of the machine, a “switch lock”
is provided on the side of a handle.
If the “switch lock” is pulled in a state where it
is pressed in the direction of the arrow mark, the
switch can be turned ON.
(2) After the switch is turned ON, even when you
release your hand from the switch lock, the body
continues running as long as you keep on pulling
the switch trigger.
(3) If you release the switch trigger, you can turn OFF
the switch and the “switch lock” returns to the
home position automatically. (Fig. 10)
3. Working Performance per Single Charge
(Reference Data)
4. Surface cutting
Rough cutting should be accomplished at large
cutting depths and at a suitable speed so that
shavings are smoothly ejected from the machine.
To ensure a smoothly finished surface, finish cut-
ting should be accomplished at small cutting depths
and at low feeding speed.
5. Beginning and ending the cutting operation:
As shown in Fig. 8, place the front base of the
planer on the material and support the planer
horizontally. Turn ON the power switch, and slowly
operate the planer toward the leading edge of the
material. Firmly depress the front half of the planer
at the first stage of cutting, as shown in Fig. 9,
depress the rear half of the planer at the end of
the cutting operation. The planer must always be
kept flat throughout the entire cutting operation.
6. Precaution after finishing the planing operation:
When the planer is suspended with one hand after
finishing the planing operation, ensure that the
cutting blades (base) of the planer do not contact
or come too near your body. Failure to do so could
result in serious injury.
CARBIDE BLADE ASSEMBLY AND DISAS-
SEMBLY AND ADJUSTMENT OF CUTTER
BLADE HEIGHT (FOR DOUBLE EDGED BLADE
TYPE)
1. Carbide blade disassembly:
(1) As shown in Fig 11, loosen the blade holder with
the attached box wrench.
(2) As shown in Fig 12, remove the carbide blade by
sliding it with the attached box wrench.
CAUTION
Be careful not to injure your hands.
2. Carbide blade assembly:
CAUTION
Prior to assembly, thoroughly wipe off all swarf
accumulated on the carbide blade.
(1) As shown in Fig. 13, lift set plate (B) and insert the
new carbide blade between cutter block and set
plate (B).
(2) As shown in Fig 14, mount the new carbide blade
by sliding it on the set plate (B) so that the blade
tip projects by 1mm from the end of the cutter block.
(3) As shown in Fig 15, fix the bolts at the blade holder
after blade replacement has been completed.
(4) Turn the cutter block over, and set the other side
in the same manner.
3. Adjustment of carbide blade height:
CAUTION
If the carbide blade’s heights are inaccurate after
above procedures have been completed, carry out
the procedures described below.
(1) As shown in Fig 16, use the box wrench to loosen
the three bolts used to retain the carbide blade, and
remove the blade holder.
(2) As shown in Fig 17, after removing the carbide
blade, slide set plate (B) in the direction indicated
by the arrow to disassemble set plate (B).
(3) Loosen the 2 screws holding on the carbide blade
and set plate (A), set plate (B).
(4) As shown in Fig 18, 19, press the turned surface
of set plate (A) to the wall surface b while adjusting
the carbide blade edge to the wall surface a of the
set gauge. Then, tighten them with the 2 screws.
(5) As shown in Fig 20, 21, insert a turned portion of
set plate (A) attached to set plate (B) into a groove
on the flat portion of the cutter block.
(6) As shown in Fig 22, place the blade holder on the
completed assembly and fasten it with the three
bolts. Ensure that the bolts are securely tightened.
Follow the same procedures for the opposite side
carbide blade.
BLADE ASSEMBLY AND DISASSEMBLY AND
ADJUSTMENT OF BLADE HEIGHT (FOR
RESHARPENABLE BLADE TYPE)
1. Blade disassembly:
(1) As shown in Fig. 16, use the accessory box wrench
to loosen the three bolts used to retain the blade,
and remove the blade holder.
(2) As shown in Fig. 17, slide the blade in the direction
indicated by the arrow to disassemble the blade.
CAUTION
Be careful not to injure your hands.
2. Blade assembly:
CAUTION
Prior to assembly, thoroughly wipe off all swarf
accumulated on the blade.
(1) Insert a turned portion of set plate (A) attached to
the blade into a groove on the flat portion of the
cutter block. (Fig. 20, 23)
Set the blade so that both sides of the blade protrude
from the width of the cutter block by about 1 mm
(Fig. 24)
(Depth of cut on soft wood is 0.5 mm)
Width of Feed speed Length
material of body of cut
45 mm 10 m/min 30 m
60 mm 8 m/min 22 m
75 mm 6 m/min 15 m
