- Always Turn off the main power breaker and lock it before carrying out any maintenance work so that someone else can not operate the machine inadvertently during maintenance work.
- After the power has been turned off for a short while, check the voltage with a multimeter or similar instrument to make sure that there is no residual voltage. Also discharge the capacitors.
- The inclined or vertical feed axes are installed with servo motor or electromagnetic brake device so that their feed axes can not slip down automatically by brake mechanism even being turned off the power.
- Do not remove or modify overtravel limit switches, interlock limit switches, proximity switches, or other safety devices.
- Maintenance work for electrical parts must be carried out by qualified personnel.
- Even if the door of the electrical cabinet is open, the power can not be cut off. When working inside the electrical cabinet or repairing the machine, always turn off the main breaker and lock it with key.
- When carrying out maintenance in high places, always use a suitable ladder or a serviceplatform and always wear a helmet.
- Always turn off the main power breaker and lock it before electrical work is carried out.
- Never approach your hands such as belts or pulleys.
- Do not start the machine until all of the removed covers for maintenance have been refitted.
- Wipe up any water or oil immediately so as not to slip and keep the maintenance area and the workplace clean and tidy at all times.
- Check that working tool is still remained around machine inside or vicinity after maintenance work: this is extremely dangerous.
- Maintenance work should be carried out by qualified personnel in accordance with the instructions of the person in charge.
- Always use the SYIL replacement parts or approval parts.
- Read the manuals thoroughly first then perform the machine operation and the maintenance work.
- Do not use compressed air to clean the machine or to remove chips.
- Always use gloves when removing chips: never touch chips with bare hands.
- When changing a fuse, check that the new fuse has the correct rating. (Using a fuse with too high a rating could result in damage to the equipment.)
- Use only the specified grades of hydraulic oil, lubricating oil, and grease or their equivalents.
Follow the instructions indicated on the instruction plate concerning the brands of oil to be used, lubrication points, amount to be used, and oil change intervals. - If one of the belts in a set has stretched beyond the prescribed limit, change the entire set.
- Stop all machine operation before cleaning the machine or the surrounding area.
- Disposal of industrial waste such as oil, coolant, chips and refrigerants is to be performed in strict compliance with environmental protection laws as stipulated by the proper national and local authorities.
