6. Arrange any tools around the machine.
7. Turn on power.
8. Turn the hand wheels of the working table (Longitudinal- and Cross–feed wheels) to perform
the face milling.
9. When finished working, turn off power, move the spindle to its top position, and release the
workpiece.
10. Clean the machine and apply a little oil to the work table to protect it.
During Operation
Note that the milling machine will shake under any of the following conditions:
a. The depth of the cut is too deep.
b. The feeding speed is too fast.
c. The rotation speed is too fast.
d. The machine and stock plane are not fixed firmly.
e. The vice and workpiece is not fixed firmly.
After Each Use
Store the machine when it is not in use according to the following principles:
• Inspect the machine for good working condition prior to storage.
• Apply a thin coat of oil on the surfaces that not painted to prevent rust.
• Store it in a dry, secure place out of the reach of children.
• The ambient temperature range suitable for storage is -4 to 104ºF (-20 to +40ºC).
Maintenance
WARNING:
• Turn the Emergency Stop switch to OFF and speed switch to 0 before making any
adjustments, changing accessories, or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
• Use only recommended accessories with the milling machine. Accessories that may be
suitable for one tool may create a risk of injury when used with another tool. Never use an
accessory that has a lower maximum operating speed than the machine itself.
Maintain the milling machine. Keep the machine in good repair by adopting a program of
conscientious repair and maintenance in accordance with the recommended procedures found
in this manual.
• Keep all cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
• Keep handles dry, clean, and free from oil and grease.
• If an abnormal situation occurs beyond regular maintenance; contact an authorized service
technician for service.
Daily Maintenance
• Inspect each operating part to ensure proper lubrication.
• Examine the working components for wear, damage or other abnormal condition.
Seasonal Maintenance
• Use a clean cotton or soft gauze to thoroughly clean each part of the machine.
• Confirm whether the motion of the machine’s spindle and fixtures are smooth or loose.
• Check whether the spindle is spinning true or wobbling.
• Check each bolt and nut for wear or damage or whether they are loose.
Examine the circuitry (contact points, conductor, plugs, and switches) to ensure normal
conditions. Maintenance of Accessories
Keep the taper shank clean.
Lubrication
In order to ensure precise operation, keep the contact faces lubricated. In the accessories that
came with the milling machine, there is an oil-can to use for lubrication. The following are the
items that need to be lubricated.
Miter Wedge Adjustment
After long-term use of the milling machine, functional error may occur due to repeated surface
motion on the wedges which act as interfaces on each slide face. In order to eliminate this error
the machine uses adjusting screws to maintain pressure between two sliding parts (ex. Spindle
Box and Fuselage) use the following information to adjust contact pressure to maintain
mechanical precision.
The following items need pressure adjustments
• Basement and saddle seat slide face (34).
• Saddle seat and working table slide face (36).

Base (1) and saddle (35) slide face
Saddle (35 and working table (19) slide face
Fuselage (68) and connecting strut (72) slide face
Fuselage (68) and spindle (79) slide face
