than remedy it after it is out of order.
(1) Daily Maintenance (by operator)
(a) Fill the lubricant before starting machine everyday.
(b) If the temperature of spindle caused over-heating or strange noise, stop machine immediately to
cheek it for keeping accurate performance.
(c) Keep work area clean; release vise, cutter, work-piece from table; switch off power source; take chip
or dust away from machine and follow instructions lubrication or coating rust proof oil before leaving.
(2) Weekly Maintenance
(a) Clean and coat the cross leading screw with oil.
(b) Check to see if sliding surface and turning parts lack of lubricant. If tile lubricant is insufficient, fill it.
(3) Monthly Maintenance
(a) Check if the fixed portion has been loose.
(b) Lubricate bearing worm, and worm shaft to avoid the wearing.
(4) Yearly Maintenance
(a) Adjust table to horizontal position for maintenance of accuracy.
(b) Check electric cord, plugs, switch, at least once a year to avoid loosening or wearing.
