2. Installation and preparation
2-1 Transportation of the machine
When lifting the machine with a crane at the factory site, insert two round bars of about
1-3/8 inch in diameter and use a wire suspension rope of sufficient strength to bear a load of
6,600 lbs. ieces of wood and cloth should be inserted at the points where the rope touches
the machine to absorb impacts which may later influence the accuracy of the machine.

2-2 Inspection and cleaning
When the machine is delivered, check for damage or shortages in the number of
attachments. Then wipe off dirt and protective coating.
2-3 Storage and installation
The surrounding condition of storage is that
Temperature range: -25 °c to 75 °C
Relative humidity range: 30% to 95 % (non-condensing)
Damage from shock and vibration should be avoided
Ingress of solid bodies and liquid should be avoided
Four leveling bolt should be adjustment the machine level.
When installing the machine must be adjustment four leveling bolt (Fig.3) for level.
2-4 Maintenance and inspection
(1) Precautions for operating
a. Always lubricate designated oil to designated oiling points before starting.
b. Confirm that the work and setting jigs do not strike anything before actuating
table feed.
c. The power table longitudinal feed should not exceed the range limitations of the
machine. Always set the automatic reversing dog on both sides within the
moving range.

2-5 Cutting oil
There are two general types of cutting oil, i.e., water-soluble cutting oil and
water-insoluble cutting oil, and these are further divided into many groups. As selection of
the cutting oil depends on each cutting condition, particular trade names or groups cannot be
specified here but it is necessary to observe the following:
(1) Use of water-insoluble cutting oil.
Examples:
Mineral oil Light oil, machine oil and spindle oil
Animal and vegetable oil
Lard, olive oil, colza oil, soybean oil and
castor oil
(2) The capacity of the cutting oil tank is approximately 9.25 gallons.
(3) Cutting oil should be supplied through an oil strainer into the cutting oil intake
provided on the lower part of the column.
2-6 Wiring
The power cord should be connected to the
terminals R.S.T. (Fig. 4-2). On completion of
the connection, turn on the power switch (Fig. 4-1)
provided on the side of the power box and turn the spindle
rotating direction indicating change over switch to the right.
After finishing the above preparations, start the main spindle.
(See section for spindle starting, spindle stopping and spindle
brake).If the rotation direction of the main spindle is
clockwise, connections are correct. If rotation is counter-
clockwise, exchange connections of two of the three wires
of the power core.
2-7 Lubrication
Prior to starting, each moving part must be lubricated with suitable lubricating oil. Refer
to (Table.1) for instructions to lubricate the spindle head gears, quill and slide ways.
The Lubrication oil to be used for each part is also listed in Table 2 and 3. It can be used
for selecting the correct lubricant to keep the machine in its best condition.
