WARNING
!!
Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities
contains chemicals known to the State of California to
causecancer,birth defects or other reprodrctive harm.
Someexamples of these chemical are:
‧Lead from lead-based paints.
‧Crystalline silica from bricks, cement and other
masonry products.
‧Arsenic and chromium from chemically-treated
lumber.
Yourriskfrom these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: Work in a well ventilated
area,andwordwith approved safety equipment, such
asthosedust masks that are specially designed to
filter out microscopic particles.

8. CLAMPING, TABLE BASE, AND MACHINE BASE (see Fig. 3)
(1) When milling longitudinal feed, it is advisable to lock the cross feed table travel to insure the
accuracy of your work. To do this, tighten the small leaf screw located on the right side of the
table base.
(2) To tighten the longitudinal feed travel of the table for cross feed milling, tighten the two small
leaf screw on the front of the table base
(3) Adjustable travel stops are provided on the front of the table for control of cross travel and the
desired milling length.
9. SPEED CHANGING (See Fig. 4)

10. TO CHANGE TOOLS
(1) Removing Face Mill or Drill Chuck Arbor
Loosen the arbor bolt (see fig. 4) at the top of the spindle shaft approximately 2 turns with a
wrench. Rap the top of the arbor bolt with a mallet. After taper has been broken loose, holding
chuck arbor on hand and turn detach the arbor bolt with the other hand.
(2) To Install Face Mill or Cutter Arbor
Insert cutter and cutter arbor into the taper of spindle. Tighten arbor bolt detach securely, but do
not over-tighten.
(3) Removing Taper Drills
(a) Turn down the arbor bolt and insert the taper drill into the spindle shaft.
(b) Turn the rapid down handle rod down until the oblong hole in the rack sleeve appears.
Line up this hole with the hole in the spindle. Insert key punch key through holes and strike
lightly with a mallet. This will force the taper drill out.
11. ORDERING REPLACEMENT PARTS
Complete parts list is attached. If parts are needed, contact your local distributor.
12. EXTRA TOOLING AND ACCESSORIES

13. TAPPING EQUIPMENT
This machine can be equipped with an electric switch for tapping operation clockwise or
counter-clockwise, and the working depth also can be adjusted by the limit switch. (Electric switch
will be installed according to your requirement, and you must pay the cost only.)
14. SPINDLE POWER DOWN FEED OPERATION
1. Select profitable spindle speed and automatic feeding rate according to cutting condition.
By adjusting the shift dial A you can obtain the feed rate you need.
2. FEEDING DEPTH SETTING:
First release the dial fix-nut E and turn the indicating ring C to the depth needed. then reset
E tightly again.
CAUTION: DO NOT LET FEEDING DEPTH EXCEEDED SPINDLE STROKE.
3. START FEEDING
Start the machine and push out the handle rod D, then the spindle will feed down automatically
Until the end of stroke you set.
4. END OF AUTO FEEDING
The spindle will return to top when reaching the end of stroke you set. when in emergency or
Desire to stop the motion during feeding, push back the handle rod D to its original place.
5. MICRO FEEDING BY MANUAL
Set the shift dial A to "0" position, and start feeding by turning F handle.
6. To prevent danger, when spindle power down feed is not in use, please lock the handle B well.

16. MAINTAINING
That's easier to keep machine in good condition or best performance by means of maintaining it at
any time 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 the lubricant is
insufficient, fill it.
(3) Monthly Maintenance
(a) Adjust the accurate gap of slide both on cross and longitudinal feed.
(b) Lubricate bearing, worm, and worm shaft to avoid wear.
(4) Yearly Maintenance
(a) Adjust table to horizontal position for maintenance of accuracy.
(b) Check electric cord, plugs, switches at least once a year to avoid loosening or wearing.
17. CLEANING & LUBRICATING
(1) Your machine has been coated with a heavy grease to protect it in shipping. This coating should
be completely removed before operating the machine. Commercial degreaser, kerosene or
similar solvent may be used to remove the grease from the machine, but avoid getting solvent
on belts or other rubber parts.
(2) After cleaning, coat all possible rusted surface with a light lubricant. Lubricate all points with a
medium consistency machine oil.

18. CHANGING THE GEAR BOX OIL
Tilt the hard stock over as shown in fig.1. Open the oil drain plug to allow the oil to drain from the
opening completely. Then lock the oil drain plug and turn the head to be upright position. Remove
the oil filler plug fill the oil to the gear box until the oil lever reach the middle of oil fluid lever
indicator. Then lock the plug.
LUBRICATION:
AII ball bearings in your mill/drill are sealed for life, requiring no lubrication. Points requiring
lubrication are:
(1) Internal spline drive assembly. Keep this area well lubricated with a good grade non-harden-
ing grease, such as Fiske Company "Lubriplate". insert grease in the hole at the top of spindle
pulley spline driver. Lube twice yearly.
(2) A light film of oil applied to the quill and column will reduce wear, prevent rust, and assure
ease of operation.
(3) Quill return spring should receive oil (SAE 20) once yearly. Remove cover plate and apply oil
with squirt can or small brush.
(4) IMPORTANT: The gear box should be oiled with a lubricant such as SAE 68 oil in level.
CHANGE OIL EVERY ONE YEAR.
(5) Apply Lubriplate To quill pinion every 90 days.
NOTE. Use extreme care when performing this operation and keep hands clear of pinch points.
When using paraffin bar, do this only by turning the sheaves by turning the sheaves by hand.
Do not apply with motor running.
19. TROUBLE SHOOTING
(1) No running after switch on:
(a) Main switch interruption while volts irregular - Adjust input voltage and draw back the main
switch.
(b) Break down of fuse in switch box - Replace with new one.
(c) In case of too much current, the overload relay jumps away automatically - Press the overload
relay, and it will return to the correct position.
(2) Motor Overheat and No Power:
(a) Overload - Decrease the load of feed.
(b) Lower voltage - Adjust to accurate voltage.
(c) Spoiled contact point of magnetic switch - Replace with new one.
(d) Breakdown of overload relay - Connect it or replace with new one.
(e) Motor is poor - Replace with new one.
(f) Break down of fuse or poor contact with wire (it is easily, to spoil motor while short circuit)
Switch off power source at once and replace fuse with new one.
