Travel Adjustment
Use the limit block (65) to control the traveling l
imit of the spindle.
1. Loosen the handle (a) beside of the limit block (b).
2. Adjust the limit block (b) up or down into position.
3. Retighten the handle.
4. Travel position can refer to the ruler on the fuselage
rotary.
Adjust Tip Angle of Fuselage
1. Turn off the electric power.
2. Hold the fuselage to keep it from falling.
3. Loosen the lock nut (a, #70) with large wrench (b)
4. Adjust the fuselage angle as needed according to
the scale (44) on the connecting strut (72).
(max angle 45º, left or right)
5. Tighten it.
Installation of a Chuck or Cutter
1. Turn off the electric power.
2. Pull out the protective cover (a).
3. Wipe off the spindle sleeve and taper shank (g).
4. If installing a cutter: Put the taper shank (g) into
the spindle sleeve. Put a cutter (i) - wrapped with
an oil cloth for safety against cuts – onto the
taper shank.
If installing a drill chuck: put the taper shank of the
chuck into the spindle sleeve.
5. Insert the fixing pin (d) right on spindle sleeve to
prevent rotation.
6. Use the #14 open end wrench (c) to tighten (clockwise)
spindle draw bar (b) to secure the cutter taper shank
or chuck taper shank.
7. Pull out the fixing pin (d). CAUTION: leaving the fixing
pin inserted will cause damage to the milling machine
when it is turned on!
8. Reinstall the protective cover (a).
Removal of a Chuck or Cutter
1. Turn off the electric power.
2. If removing a cutter, wrap the cutter in an oil cloth for safety against cuts.
3. Pull out the protective cover (a).
4. Insert fixing pin (d) right on spindle sleeve to prevent rotation.
5, Use the #14 open end wrench (c) to loosen (counter-clockwise) the spindle draw bar (b).
6. Tap the cutter taper shank (g), or drill chuck taper shank, gently with a plastic hammer to
loosen it in spindle sleeve. Then remove the taper shank (g).
7. Install the protective cover (a).
Operating Instructions
WARNING:
• Do not use the machine with a malfunctioning switch. Any power tool that cannot be
controlled with the power switch is dangerous and must be repaired by an authorized service
technician before using.
• Use only recommended accessories with the 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.
• Never operate the tool without the guards in place.
• Do not leave the tool running unattended.
• In the event of a power failure while a tool is being used, turn the Emergency Stop switch to
OFF and speed switch to 0 to prevent surprise starting when power is restored.
Normal Starting
WARNING:
• NEVER change from the HIGH to LOW setting when the machine is running.
1. Perform all the pre-start checks in the Before Each Use section and ensure the work piece is
secured in place.
2. Set the speed range control lever to HIGH or LOW as required.
3. Release the Emergency Stop Switch (A) by pushing down on the red knob slightly and
pushing it up, as indicated by the arrow on the top of the red knob.
4. Turn on the machine by GENTLY turning the Variable Speed Control knob (D), clockwise.
Turn the knob to the desired speed for the workpiece.
5. Begin operation according to the appropriate section below.
ATTENTION:
The power supply system of this machine has an auto over-load protective
function. If the feeding is too fast or drilling is too deep, the system will stop working, a yellow
lamp (B) lights. Turn off the Variable Speed control knob (D) then turn it on again. The system
will work again and the yellow lamp will extinguish automatically.
Drilling or Milling Speed
Before any operation, set the spindle to a correct speed for the work.
The operating speed range for working is 0 to 2500 rpm, For the most part, the correct speed
may consider the size of working face and the material. Generally, use a higher speed for softer
materials or smaller holes. Use a lower speed for harder materials or bigger holes.
A good rule of thumb is: For smaller hole and the softer material, please use higher speed. But
don’t drill too fast (above 2300 rpm) if your workpiece is wood, you may burn it. For metal, the
speed can from 0 to 2500 rpm.
Drilling or Deep Milling
1. Replace the chuck or cutter according to the ‘Before Each Use’ instructions.
2. Select the appropriate speed level.
ATTENTION:
Never change the High/Low speed while the spindle is spinning!
3. Use a fixture to secure the workpiece on the working table.
4. Adjust the working table (Longitudinal- and Cross–feed wheels).
5. Loosen the limit block handle and adjust the block position. Note: don’t let tool meet the workpiece.
6. Remove any tools and items from around the machine.
7. Turn on power.
8. Refer the ruler on fuselage can know drilling or milling depth.
9. When finished working, turn off power and move the spindle to its top position.
10. Clean the machine and apply a little oil to the work table to protect it.
Face Milling
1. Replace the chuck or cutter according to the ‘Before Each Use’ instructions.
2. Select the appropriate speed level.
ATTENTION:
Never change the High/Low speed while the spindle is spinning!
3. Use a fixture to secure the workpiece on the working table.
4. Adjust the working table (Longitudinal- and Cross–feed wheels).
5. Loosen the limit block handle, and adjust the block position. Note: don’t let tool meet the workpiece.
