general safeTy rUles for all machines
N.B.: Read the instructions carefully in order to avoid any problems.
As with all machinery there are certain hazards involved with operation and use of this machine. Using the
machine with respect and caution will considerably lessen the possibility op personal injury. However, if normal
safety precautions are overlooked or ignored, personal injury to the operator may occur. Observe these rules
insofar as they are applicable to this particular machine.
This machine was designed for certain applications only. We strongly recommend that this machine NOT be
modified in any way and/or used for any application other than for which it was designed.
If you have any questions relative to its application DO NOT use the machine until you have contacted your
dealer.
1. For your own safety read the instruction manual before operating the tool.
2. Keep all guards in place and in working order.
3. Ground all tools.
4. Remove adjusting keys and wrenches. Make a habit of checking the machine before turning it on.
5. Keep the work area clean. Cluttered areas and benches invite accidents.
6. Do not use in a dangerous environment, such as damp or wet locations or expose to rain. Always keep the
work area well-lit.
7. Keep children and visitors away. They must be kept at a safe distance from the machine at all times.
8. Make sure that the work area is not accessible to unauthorised persons. Use padlocks, master switches,
remove starter keys etc.
9. Never overload the machine. The capacity of the machine is at its largest when properly loaded.
10. Do not force the machine or attachment to do a job for which it was not designed.
11. Wear proper apparel. No loose clothing, gloves, neckties, rings, necklaces, bracelets or jewellery: they may
get caught in moving parts. No slip footwear is recommended. Wear a hairnet to contain long hair.
12. Always wear safety glasses and work according to safety regulations. Use a face or dust mask if operation is
dusty.
13. Always secure workpiece tightly using a vise or clamping device. This will keep both hands free to operate
the machine.
14. Do not overreach. Keep your proper footing and balance at all times.
15. Maintain tools in top condition. Keep them sharp and clean. Read the instructions carefully and follow the
instructions for cleaning, lubrication and tool replacement.
16. Lubricate the machine and fill all oil reservoirs before operation.
17. Disconnect tools before servicing and when changing accessories such as blades, bits, cutters etc.
18. Use only recommended accessories. Consult the owner’s manual for recommended accessories. The use of
improper accessories may cause hazards.
19. Avoid accidental starting. Make sure the on/off switch is in the “OFF” position before plugging in the power
cord.
20. Never stand on the machine or tools. Serious injury could occur if the machine is tipped or if the cutting tool
is accidentally touched.
21. Check damaged parts. Replace or repair damaged parts immediately. Check machine for alignment of
moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may
affect its operation.
22. Direction of feed. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.
23. Never leave tool running unattended. Do not turn power off until it has come to a complete stop.
24. Alcohol, medication, drugs. Never us the machine while under the influence of alcohol, medication or drugs.
25. Make sure the tool is disconnected from the power supply, before servicing, repairing etc.
26. Keep the original packing for future transport or relocation of the machine.

Additional safety rules
Always keep in mind that:
• the machine must be switched off and disconnected from the power supply during maintenance and repairs,
• clamped workpieces may only be measured when the machine is switched off.
Never lean over the machine, mind loose clothing, ties, jewellery etc. and wear a cap.
Do not remove safety devices or guards. Never use the machine while a guard is open.
Always use safety glasses for machining rough materials.
Burrs and chips should only be removed using a sweeper or other aid, never with your bare hands!
Never leave the machine running unattended.
Always wear safety glasses.
2. M
ain specificaTions anD feaTUres
This is a general- purpose drilling machine for hole machining operation. Two sets of motions, one is the
rotational movements of the spindle in its transmission box, the other is the rotational and vertical travel
movements of the spindle box along the vertical column, fulfil the machining operations of drilling, tapping,
reaming, boring, chamfering and spotfacing on different shapes of workpieces. The gear transmission system has
been applied, Which results in the compact structure and high rigidity to meet the needs of strong force cutting
operation. The double-speed motor has led a wide speed range and very easy and safe shifting. The drilling
machine suits the needs of machinery manufacturing and various kinds of repairing applications.
3.
several Usage regUlaTions
1. Carefully read this user manual before start the machine.
2. Wearing gloves is not allowed when operate this machine, contacting the spindle and tools are also
forbidden when it is running.
3. The workpiece must be safely fastened, holding it with hands when in operation is strictly objected.
4. The machine has not short – circuit protection, the user is so required to connect a 6A protection switch.
Earth protection mist be well done.
5. Whenever a failure happens, call the qualified personal to repair it.

The vertical column is mounted on the bottom base, loosen the fasten handle 63 ( fig.5 ) and rotate handle 17
( fig.2 ), the spindle box can move along the vertical column, loosen the fasten handle 63, the spindle box fixed
at any position, so to suit the different machining requirements, loosen cover nut 73 ( Fig.5 ) and rotate nut 72,
the swivel angle of the fasten handle can be adjusted and the tightness of the spindle box can also be changed,
when adjustment completes, fasten the cover nut.
The gear box is mounted on top of the spindle box, rotate the feed handle 89 ( Fig.5 ) the spindle will move up
and down along with the sleeve Remove the gear box, loosen the anti-motion washer 41 ( Fig.4 ), adjust nut 40,
the clea ance of the spindle bearing can be altered. The above adjustments have been set when put to shipment,
nonqualified personal is not allowed to de this adjustments.

Transmission sysTem
The spindle rotate ( Fig. 6 ) through motor and gear 95;126 or 99;100 to shaft . Through gear 102; 123 or 108;119
to shaft. Through guide and transmission key to spindle. The motor has double- speed, through changing the
transmission gears, the spindle will rotate in 8 grades of speeds.
Spindle feed motion. The spindle feed movement is controlled manually, the handle 88 ( Fig.5 ) through gear,
gear rack transmission, to make the spindle sleeve move downwards so realise the feed motion.
The up and down motion of the spindle box. It is also controlled by hand, loosen the fasten handle 63 ( Fig. 5 ),
move handle 17 ( Fig.2 ), the spindle box will move up or down.
8.
operaTion
Before start the motor, first rotate the change switch ( 21 ) on the spindle box till teach the required position (
high speed to “2R”, Low speed to “1R”, low speed and reverse direction to “1L” ) , then press down the start switch
“1” (green) ; for stop the machine press “O” button ( red ): for reverse rotation, fist to stop the machine and rotate
the speed change switch to “1L” or “2L” wait till the motor to stop completely and then press the start switch.
The speed selection is realised through handle 133 ( Fig.7 ), adjust handle 133 to realise 4 kinds of speed
variations, matched with double speed motor, we can gain 8 grades of speeds ranging from 100 rpm to 2900 rpm.
It should be noted that the speed variations could only be done when the machine has stopped so to avid any
possible damages to the gears and couplers.
About the drilling depth, you only need to adjust the nut 38 ( Fig.2 ) to the require dimension. The drill automatic
release applies to GB1443-85 (ISO 296-1974 ). Morse 3 outer taper with flat tail, its operation is 1:ke this: put out
the handle 48 ( Fig.4 ), rotate handle 88 ( Fig.5 ), then the sleeve will lead the drill to the highest position, the drill
end touches the enter shaft end so to be pushed out, then push 48 to its original position, install the tool.

TransporTaTion anD insTallaTion
Before lifting the machine for transportation, the spindle box must be fastened first.
The machine can be installed on any hard place, it can also be tightened by bolts.
