9. 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.
Before operation
-
Fill the lubricant.
-
In order to keep the accurate precision, the table must be free from dust and oil deposits.
-
Check to see if the tools are correctly set and that the work piece is set firmly.
-
Be sure that the speed is not set too fast.
-
Be sure that everything is ready before use.
After operation
-
Turn off the electric switch.
-
Turn down the tools.
-
Clean the machine and coat it with lubricant.
-
Cover the machine with a cloth to keep out the dust.
Adjustment of the head
-
To raise and lower the head, loosen the two heavy duty head lock nuts shown in Fig. C. Use the left side
handle head handle to raise and lower the head on its rack and pinion mechanism. When the desired
height is reached, tighten the bolts to avoid vibration.
-
The head may be rotated 360 by loosening the same bolts mentioned above. Adjust the head to the
desired angle, then fix the heavy-duty head locknuts. Tighten it to fix the head for extensive drilling and/or
milling.

10. Quill return spring adjustment
The spring tension for the return of the spindle after drilling
The tension of the spring that will return the spindle to the initial position after drilling has been pre-set in the
factory. Do not adjust the spring tension unless it is absolutely necessary, e.g. when using a multiple spindle
drilling or tapping head. Proceed as follows to adjust the spring:
Hold the quill spring housing and loosen the lock screw. Make sure that the housing is turned in your hand,
otherwise the spring will unwind. Turn the spring housing clockwise the necessary number of turns around
until the quill return to the most upper position (the flat of the spring housing pilot is in line with the spring
loading hole on the body of the spring housing). Lock the screw and make sure that the tip of the screw is
located at the flat part of the housing journal.
Preparing for drilling (see fig. C) (Except additional power feed system)
-
Turn the knob to loosen the taper body of the worm gear and spring base. Set the spindle stroke by using
the positive depth stop gauge.
Preparing for milling (see fig. C) (Except additional power feed system)
-
Adjust the positive depth stop gauge to the highest point possible.
-
Turn the knob to couple the taper friction force to the worm gear and spring base. Turn the handle wheel
to adjust the working height of the spindle with that of the work piece.
-
Lock the rack sleeve with a fixed bolt at the desired height
