USAGE
The machine is used for cutting metals and nonmetals. It's suitable to drill, mill
and widely use in the field for instrument, machining, repairing for cutting a single
part or a batch of parts.
II USE AND MAINTENANCE
(Refer to chartg 1.)
1. The user must read the operation manual carefully, know structure and ability
of every handle, the system of transmission and lubrication well.
2. Before operating, inspect the normal conditions of the column lock handle, the
spindle sleeve and electric equipments. The ground line must be connect in the
ground.
3. When the position of spindle box to the working table need to be adjusted,
two clamping shaft ①locating on the right side of hoist--de-scend sliding must be
lossed firstly, then turn the hoist--descend handle in front of machine, to hoist or
descend the working table to the idea position, finally clamp the clamping shaft ①.
4. A micro--feeding institute is applied to the machine, before using, pls turn
locking bolt ③in right side to form the handle body with micro-feeding can be
realized. The spindle can revolve for tapping, through the universal switch equipped
on the left side of the head.
But if the power motor is single phase, such function can't be realized.
5. The handle body must be separated from micro-gear during drilling, when
drilling finished, loosen the handle ⑤, the sleeve will reset automatically. The elastic
force can be adjusted after loosing the screw locating in the bottom of spindle box

7
and turning the spring to different position. The spindle sleeve clamping handle ⑥
should be clamped for milling. To obtain the best effect, pls choose the 3-blade
vertical milling tool, the most, the working table must be hoisted to the nearest
position to the spindle when the 2-blade milling tool is used.
6. The boring function can be realized after equipping relative accessories. It is
better to apply to micro-feeding during milling and boring.
7. The spindle box can turn ±90°in vertical plane for turning the spindle box,
pls firstly loosen the three tighting nut connecting with spindle box, turn the spindle
to the needed angle through turning micro-worm ⑧, finally pls tight the nut.
8. The cross-slide of spindle box can be realized through the ram moving for
cross-sliding, pls firstly loosen the two clamping bolts ⑨locating on the right side of
the ram, turn the gear shaft ⑩, to move the ram and spindle box, and tight the two
clamping bolts.
9. The spindle box can turn 360°around the column in the horizontal plane. To
realize this, pls firstly loosen the 4 pcs of clamping nuts ⑾under the ram, turn the
ram to the suitable position, finally tight the 4 pcs of clamping nuts.
10. The spindle's turn and revolve can be realized by the switch located in the
right side of hoist-descend sliding.
11. The horizontal milling can be realized by turn the vertical spindle box 90°.
The spindle box must turn 180°when the tool shaft and jack applied for assistance.
12. If the machine doesn't work well or have irregular noise, pls immediately shut
off machine.

IV THE SYSTEM OF TRANSMITION
AND CHANGED SPEED
1. Vertical shaft: when changing speed, open the two side cover of upper spindle box,
loosen the tightened bolt of motor, move handle on the rightside to loosen the belt,
change belt to the position needed, remove motor and make belt fitted, tighten the
tightened bolt and then work.
Horizontal shaft: when changing speed, open the cover of the vertical column,
first loale the nut lie between vertical column and the support of motor, then loosen
nut that make belt loosed or tightened, adjust belt to the position required finally
tighten the nut.
2. The gear machine power is transmitted through gear on the shaft of motor and
moving gears to the gear of spindle, when change speed, first cut off power, then
change the handle to the position (A of B, C or D) you want.
3. H/V drilling and milling machine power is transmitted from motor to spindle
through V-belt and trichanged speed.
NOTICE: Stop motor before changing speed!
Ⅴ
THE LUBRICATION OF MACHINE
AND ROLLING BEARING

10
1. Each rolling bearing to lubricated with lubricating fat on time (prefer to chart-2).
2. Spindle, sleeve, column, table etc. Should be lubricated at the right moment.
Ⅵ
ELECTRIC SYSTEM
1. The electrical control system to be equipped in the left-side machine head, the
control electrical system of horizontal spindle to be equipped under the right-front.
Electrical circuit adopt the advanced international cornponent to make up, which
make the machine easy to operate and safe.
Ⅶ
TRANSPORT AND ATTENTION
1. While transporting machine, must be careful to carry and put down.
2. In one year, we make promise to provide aftersales service.
3. Before use the machine, the power feed the spindle's running and the coolant's
running must be the same direction as the label. Otherwise two phase of power cord
must be exchanged. (power feed and coolant optional accessories.)
Ⅷ
SIMPLE MALFUNCTION & OBVIATION
1. If the motor does not turn, please inspect it is right to connect wire or check
electrical source.
2. If the radial run out of spindle is big with noise and heat, please inspect wether
spindle is too loose. Pls spindle the nut on the spindle assembly to the fittest.
3. When the machine wobble, pls check the motor mount and lever lock nut screw,
machine head support on the spindle, if loosing, pls adjust and lock.
4. It is difficult for the spindle to rise, fall or not replacing, pls inspect wether there
is scrap iron and other something in the connection between spindle sleeve and gear

11
shaft and fatigue of spindle. If finding them, pls clean them and apply oil and adjust
spring to fittest.
5. If the knee table slide carriage does not rise steadily with noise, the table is
steady, pls confirm wether wedge ship loose or not, and clean scrap iron, add oil
adjust wedge ship to fittest.
6. If there is noise in gear box, pls stop machine immediately to conform the position
your require, then check that the oil meet standard.
7. Prohibited maintaining the machine with electric.
NOTICE
I: The spindle box that transmitted by the belt can be surivled at 90°(by gear
±45°). When operating, pls loosen the three retaining but and pay attention these
nuts need only 1 pitch, then swivel screw lever by socket head screw wrench (s21-24)
to make the spindle box swivel to the place required (clockwise turn the nut, the
spindle box will cunter clockwise turn, or otherwise), while turning, pay attention to
the following item:
i:while the spindle box turn from horizontal position clined position to vertical
position pls help push the upper of spindle box and gently twitter it.
ii while the spindle box turn from verival position to horizontal position or clined
position, pls push the upper of spindle box with hand and twitter it gently.
II:The rotary table (optional) can surivle at 45°when operate, first loose two screw

12
of back way cover and remove the way cover. Then loose the four nut, turn the table
to the direction you want.
III:Adjust the perpendicular between spindle and table gauge magnetize on end face
of spindle. Tracing pin turn 360°about dia Φ250-300mm on the surface of the table.
This is perpendicular between spindle and table if measuring range is variable
between 0 and 0.02mm.
