2. Installation and preparation
2-1 Transportation of the machine
Make certain the load is on balance and that the sling does not touch the table or head before lifting.
If a crane is used in lifting, exercise care that none of the mechanism is damaged.
When lifting the machine, insert two round bars of about 35mm in diameter and use a wire
suspension rope, be certain that they are strong enough to safety carry the weight of the machine.
The finished surface of the machine must be protected by using wooden blocks and cloth.

2-2 Inspection and cleaning
After you received the machine, please check if the packing contents all the accessories you
ordered. Then wipe off dirt and protective coating.
2-3 Storage and Installation
The surrounding condition of storage is that
Temperature range: -25° to +75°
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
1) Always supply lubricating oil to designated oiling points before starting.
2) onfirm that the work and setting jigs do not strike anything before actuating table feed.
3) 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 Lard olive oil colza oil soybean oil,
Vegetable oil castor oil
(2) apacity of the cutting oil tank is about 9.25 gallon.
(3) utting oil should be supplied through an oil strainer into the cutting oil intake provided on the
lower part of the column.
Warning: 1. To avoid fire, prohibited use low flash point cutting oil for machining magnesium,
aluminum or similar pyrophoric or explosive articles.
2. Do not dump waste cutting fluid at any place. Dispose the waste fluid under
regulation of local low for environmental
protection.
2-6 Wiring
The power cable should be connected to the terminals R.S.T.
(1) (Fig.4). On completion of the connection, turn on the
power switch provided on the cabinet.
After finishing the above preparations, start the main spindle.
(See section for spindle starting, spindle stopping).
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
cable.
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 gears and sideways.
The lubrication oil to be used for each part is also listed in tables 2, and 3, it can be used for
selecting the correct lubricant to keep the machine in its best condition.

3-6 Change of horizontal spindle speed
Move lever (1)(Fig.7) to position  .  or  depending upon the spindle speed
range required,and move lever (2)(Fig.7) to the position of the particular speed reuqired.Speed
changes must not be made while the main motor is running. To facilitate changing spindle
speed,stop main motor by depressing horizontal spindle stop button (2)(Fig.6). Turn spindle
rotated direction switch (3)(Fig.7) to position 1 or 2 and then intermittently press the inching
button (4)(Fig.7), at the same time moving lever (2)(Fig.7) until the required gears are engaged.
It should be noted that the feed motor will automatically stop when the inching button is
operated.

Operate longitudinal feed by hand wheel (1) (Fig.5), cross feed by habd wheel (2) (Fig. 5),
and vertical feed by hand lever (3) (Fig. 5).
If directional changing lever (4) (Fig. 5) at central frontof saddle is in neutral position,
longitudinal manual feed can not be operated.

3-7-2 Operation of cross power feed
Start feed motor by turning button (3) (Fig. 6) and then lever (5) (Fig.5) upwards for the
saddle to feed towards the column, and for the saddle to feed away from the column move
lever (5) (Fig.5) downwards.
3-7-3 Operation of vertical power feed
Start feed motor by turning button (3) (Fig. 6) and then move lever (6) (Fig. 5) upward to
feed the knee upwards to move lever (5) (Fig. 5) downward, to feed the knee downward.
3-7-4 Operation of longitudinal power feed
Start feed motor by turning button (3) (Fig.6) and then move lever (6) (Fig.5) and then
move lever (4) (Fig.5) right for the table to feed from the left move the right and for the
table to feed from right to left mover lever (4) (Fig. 5) to left.
3-7-5 Choice of feed speed
Feeding speed is dependent on the spindle speed, material of work piece, tips if cutter and
diameter of cutter (Table 6). With this machine, 12 steps of cutting feed and rapid feed are
carried out from the feed box which is under the side of saddle.
Turning the switch (3) (Fig. 6) to “ON” position to start the table longitudinal feed motor.
Move lever (10) (Fig. 5) to position A, B or C dependent upon feed range required and
move lever (9) (Fig. 5) to the position for the particular feed rate required. It is not
necessary to stop the feed motor when changing the feed rate.
“WARNING”
1. Don’t change feeding speed if the table is moving.
2. Before stopping the spindle or when the table auto feed is not used push back the feed
engagement lever (4) (5) (6) (Fig. 5) to neutral.
3-7-6 Operation of rapid traverse
This can be operated on any of the foregoing movements by having the fees motor running
which is independent of the main spindle motor and moving the lever whichever direction
engages the feed required into the correct position and then moving lever (11) (Fig. 5)
upwards until the appropriate distance has been moved. Then lever (11) (Fig. 5) should be
returned to its neutral position.

3-7-7 Backlash eliminator
The use of the backlash eliminator device allows “climb milling” to be carried out on this
machine. The backlash eliminator controller (8) (Fig. 5) is situated on the front of the
saddle. When climb milling is to take place with the cutter revolving clockwise and the
table moving from right to left, the backlash eliminator control should be rotated counter –
clockwise.
To set the backlash eliminator turn the controller (8) (Fig. 5) in the appropriate direction
and at the same time rotate the table hand wheel. Continue turning the controller (8) (Fig. 5)
until resistance is felt at the table hand wheel.
Do not over tighten the backlash eliminator.
The table must not be put into rapid traverse when the backlash eliminator is engaged.
3-7-8 Operation of dog
The auto-stop longitudinal feed is worked by dogs which are located in the T-slot front of
table. The two fixed dogs (2) (3) (Fig. 8) on the outsides are safety stops which prevent
over travel. These should not be moved.
The two inside dogs (4) (5) (Fig. 8) can be set at any position so that the table stops
automatically in set range.
