1. 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.

2. 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!
1. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contain chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead based paint.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area and work with approved safety
equipment, such as face or dust masks that are specifically designed to filter out microscopic
particles.
2. Permanently connected tools:
This tool should be connected to a grounded metal permanent wiring system; or to a system
having an equipment-grounding conductor.
3. For your own safety read instruction manual before operating drill press
• Wear eye protection.
• Do not wears gloves, necktie, or loose clothing.
• Clamp work-piece or brace against column to prevent rotation.
• Use recommended speed for drill press accessory and workpiece material.
Intended use
The machine is suitable for direct and using conventional milling and drilling operations of metals and
plastics. The processing of other materials is inadmissible or must be carried out in special cases only
after CONFIRMED with the machine manufacturer.
The intended use also includes compliance with the manufacturer’s specified operating - and the
maintenance and repair instructions. The machine must only persons who are familiar with the
operation, maintenance and repair, and are informed about the dangers, operated and supervised.
All accident prevention and safety instructions for working with the machine tools and CNC machine
tools must always be respected. With improper use of the machine by the manufacturer liability will be
accepted, and the responsibility solely to the user transmitted.

• Required cable: 4-pole (PE, L1, L2, L3) ; Fuse: 16 A
• Confirm power at the site matches power requirements of the mill before connecting to the power source.
• Cannot change the voltage from junction box cover on the motor and the wires according to the diagram found
on the inside of the cover.
• Before hooking up to the power source, make sure that the switch is in the OFF position.
• The mill must be properly grounded.
• Check for proper spindle rotation in the high-speed range. The spindle should rotate clockwise when viewed
from the top of the machine. If the spindle rotates counter-clockwise, then there are
