5. Transportation and Installation of Machine
5-1. Transportation and Unload Machine
◆Machine Unloading Method
During movement, transportation and unloading of
this machine, please put down the arm to the lowest
level, the spindle box at position ⓑ, the working
table at position ⓐ, adjust ⓔ zig at ⓒ, ⓕ zig at
the end of the T groove, and fixate the spindle box,
arm, and column sleeve completely.
Please adjust a strong enough rope or other
instrument to the center of the machine as shown in
the following picture and use protection pads like a
thick fabric to prevent the rope from directly touching
the slideway face of the arm. Before lifting up the
machine, please recheck the centers of the rope and
machine.
◆Transportation Method of Machine
During transportation of the machine, please adjust
the center equivalent to the unloading method, fixate
the arm and column sleeve firmly, use protection
pads like a thick fabric to protect the machine as
shown in the picture with strong enough rope, and
fixate the machine firmly as shown in numbers 1, 2,
3, and 4 in the picture to transport.

Connect Electric Power source, R.S.T to
terminals. After power on, press “NO”switch in
front of machine, and Pilot Lamp will be lighted
up. In case of not being lighted up, two lines
among three lines of power source should be
exchanged.
☆ Be sure to ground the Earth.
5-3. Product Installation
This machine is able to demonstrate its capability if enough installation space is secured on
the solid ground for convenient work and maintenance.
For the foundation, please increase or decrease the thickness of the concrete according to the
ground in order to prevent sinking or generating cracks due to the weight of the machine and
processed object. For the installation area, please avoid direct sunlight and install without
any vibration.
The foundation shall be accompanied by the following basic drawing.

5-4. Balance of Product
Balance of the machine is very important to
maintain its processing precision and
durability.
When the machine is initially installed, if it
is hard to maintain balance due to long period
of packing condition or a deformation generated
during transportation and unloading, please
carry out balance work in several weeks after
installation.
Also, in order to maintain the precision of the
machine, please check the balance condition of
the base periodically.
Work Method
⦁ After fitting leveling plate to foundation
bolt, lift machine to fit it to slot of leveling
bolt attached on base and then fasten washer and
nut.
⦁ After machine is installed on foundation, put
level on Base followed by adjusting the level and
then fill concrete or mortar around Foundation
Bolt.
⦁ After foundation is completely hardened, be
sure to set the leveling more exactly.
⦁ After foundation is completely set, remove
rustproof oil applied on workable parts of
machine and then apply machine oil or the same
kind of oil on slide surface of Arm, Column
Sleeve, etc.
⦁ please supply machine with oil as instructed
in oiling list.
⦁ By connecting electric lines, put Arm on the
center of Column Sleeve and Spindle Box on the
center of Arm, and then clamp Spindle Box and
Column Sleeve.
⦁ Firstly, put the Level in unit of 1/100 mm/m
position to right and left by adjusting with
Leveling Bolt. If there is not and problem,
gently tighten Foundation Bolt in consecutive
order. If leveling is well done, please tighten
it fully.
⦁ Leveling should be adjusted as much as the
center of Base is formed concave. When horizontal
is finished, put a cover over the place of
Foundation Bolt of Base.
5-5 Fueling
To maintain durability and function of machine
for a long time, please check oiling condition
periodically and be careful not only to use oil
appointed but also to keep oiling times and that
to be exchanged.
Before operating machine, be sure to check oiling
list.
5-6 Spindle Box
Lubrication of the spindle box lubes through the
plug on the top of the spindle box cover, and
the exhaust is through the plug under the back
of the spindle box.
The oil flow should be at the center of the oil
level on the front of the spindle box(when the
machine is operating).
The gear and bearings inside the spindle box are
forcible circulation by the trochoid pump.
When operating the spindle box, be sure to
confirm the lubrication condition with the fluid
on the left side of the box from time to time.
5-7 Arm Elevating
Lubrication and discharge through the plugs on
the upper and lower arms of the upper and lower
arms. The fueling amount should be at the center
of the oil level on the front of the box. Fill
the arm and column sleeve with lubricant once a
day through two ball caps on the back of the arm.
☆To the other places to be oiled, please follow
as oiling list and oiling diagram.

* The oil supply periods were set taking into account the oil component on a basis of an 8-hour operation per
day. As each oil’s life is affected by many factors such as change of viscosity resulting from
the conditions of use, environment (temperature, humidity, etc.), and oil deterioration,
be sure to determine the exchange period after checking the oil conditions.
