*NOTE Coolant should be prepared using deionized or distilled water for best results Tap water containing various chemicals and
minerals can leave deposits on machine surfaces causing premature wear corrosion or component failure
Polycarbonate Windows/Guards
All windows and guards should be periodically checked for discoloration cracking or other signs of damage/wear Polycarbonate can
be weakened by exposure to coolant cutting fluids and chemicals containing amines Windows/guards should be replaced if
degradation is suspected It is recommended that all polycarbonate windows/guards be replaced every 2 3 years
Safety devices
Safety devices are provided to ensure that operators are protected at all times It is essential that these are checked on a regular basis
to ensure that they are working correctly Contact your dealer immediately if any of these devices require servicing Â
Device Description of Maintenance
E Stop Push the Emergency Stop button after daily start up according to operators manual

If this function is not allowed the safety device is operating properly
Main Power Switch Check the tightness of the holder every six months if loose it must be tightened If the fixing screw
between the holder and link wears a replacement shall be fitted according to the specification on the
electrical parts list
Machine Storage
Storage temperature range 4°F to 158°F 20°C to 70°C
Antirust coating should be applied to all metal surfaces before storage of machine
Any water based coolant or other fluids should be completely removed from machine and all hoses drained prior to storage
If the machine will not been used for more than six months the spindle and axis drive belts should be loosened to prevent fatigue from
long term tension
