moving parts binding of moving parts, breakage of parts mounting, and any
other conditions that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced.
21.DIRECTION OF FEED. Feed work into a blade or cutter against the
direction of rotation of the blade or cutter only.

motor is being mounted, connected or reconnected.

ADDITIONAL SAFETY RULES FOR MILL DRILL
1.BE SURE drill bit or cutting tool is securely locked in the chuck.
2.BE SURE chuck key is removed from the chuck before turning on power.
3.Adjust the table or depth stop to avoid drilling into the table.
4.SHUT OFF the power ,remove the drill bit or cutting tool, and clean the
table before leaving the machine.
5.CAUTION. When practical , use clamps or a vise to secure workpiece to
keep the workpiece from rotating while the drill bit or cutting tool.
6.WARNING: FOR Your Own Safety Don't wear gloves when operating a
mill/drill.

CLEANING
(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 bright work with a light lubrication . Lubricate all
points with a medium consistency machine oil.
LUBRICATION:
All 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 grease , 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) 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 hand. Do not apply with motor running.
USE OF MAIN MACHINE PARTS
(1) To raise and lower the head by head handle.
(2) Equipped with an electric switch for tapping operation clockwise or
counterclock wise.
(3) To adjust the quick or slow feeding by feed handle.
(4) To adjust the table left and right travel by table handle wheel.
(5) To adjust the table fore and after travel by table handle wheel.
(6) To operate the spindle handle wheel for micro feed.
(7) To adjust the scale size according to working need.
PRECAUTION FOR OPERATION
Check all parts for proper condition before operation; if normal safety
precautions are noticed carefully, this machine can provide you withstanding
of accurate service.
(1) Before Operation

(a) Fill the lubicant
(b) In order to keep the accurate precision,the table must be free from
dust and oil deposits.
(c) Check to see that the tools are correctly set and the workpiece is set
firmly.
(d) Be sure the speed is not set too fast.
(e) Be sure everything is ready before use
(2) After Operation
(a) Turn off the electric switch.
(b) Turn down the tools.
(c) Clean the machine and coat it with lubricant.
(d) Cover the machine with cloth to keep out the dust.
(3) Adjustment of head
(a) To raise and lower the head, loosen the leaf screw located on the
right side of the raise and lower base. When the desired height is
reached tighten leaf screw to avoid vibration.
(b) Unscrew 3 nuts while the workpiece needs to be bevel turn to the
degrees you wish on the scale ,then screw the 3.
QUILL RETURN SPRING ADJUSTMENT:
Spring tension for return of spindle, after hole drilling, has been pre-set at
the factory .No further adjustment should be attempted unless absolutely
necessary. Adjustment will probably be required if a multiple spindle drilling
or tapping head is used .If adjustment is necessary ,loosen lock screw while
holding quill spring housing .Do not allow the housing to turn in your hand,or
spring will unwind. Turn entire housing assembly clockwise the number of
turns necessary to cause the quill to return to its up position.(NOTE: The flat
of the spring housing pilot is lined up with the spring loading hole on the body
of the spring housing.)Reset lockscrew make sure point of screw mates the

flat on the housing journal.
(1)Preparing for Drilling(see fig.2)(Except addition power feed system).
Turn of the knob make loose the taper body of worm gear and spring
base. Then we decide spindle stroke setting the positive depth stop
gauge for drilling blind hole or free state for pass hole.
(2)Preparing for Milling (see fig.2)(Except addition power feed system).
(a)Adjust the positive depth stop gauge to highest point position.
(b)Turn tight of the knob be use to taper friction force coupling the worm
gear and spring base. Then turning the handle wheel by micro set the
spindle of work piece machining height.
(c)Lock the rack sleeve at the desired height with fixed bolt.
ADJUSTING TABLE SLACK AND COMPENSATE FOR WEAR(see fig.3)
(1) Your machine is equipped with jib strip adjustment to compensate for
wear and excess slack on cross and longitudinal travel.
(2) Clockwise rotation the job strip bolt with a big screw for excess slack
otherwise a little counter clockwise if too tight.
(3) Adjust the jib strip bolt until feel a slight drag when shifting the table.
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
Fig.3
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.

TO CHANGE TOOLS
(1) Removing Face Mill or Drill Chuck Arbor
Loosen the arbor bolt at the top of the spindle shaft approximately 2 turns
with a wrench. Rpa 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 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 lightly with a mallet.
This will force the taper drill out.
