8. Operating Precautions

The following operating and safety precautions
must be observed in order to avoid harm to the
operator or damage to the drill press.
1. Make sure the power voltage is for the
machine. Before connecting the plug to
socket, it is necessary to check the power
spec. to avoid any damage occurring.
2. If the machine is not used for a long time,
the plug should be disconnected.
3. Never put the power cable near the fire or
water environment, to break or press the
power cable is not allowed.
4. The head assembly must be locked to the
column so the thrust produced by drilling
will not force the head assembly up the
column.
5. The work table must be locked to the
column so it will not be forced down the
column.
6. Before drilling, release the quill lock nut to
permit free travel of the quill.
7. Be sure the belt is tightened to the proper
tension.
8. DO NOT start to drill the work piece until
making certain the work piece is held down
securely.
9. MAKE SURE THE DRIVE MOTOR IS RUNNING
BEFORE turning the speed control
hand-wheel in either direction.
10. Point of operation protection is required for
maximum safety. This remains the
responsibility of the
since conditions differ between jobs.
11. Make sure the drill is secured in the spindle
or chuck before attempting to use the drill
press.
12. Make sure the spindle taper is clean and
free of burrs, scoring, and galling to assure
maximum gripping.

9.1. Replacement of V-Belt

This machine is designed with 2 step pulleys
and V-belt to provide braking response and
torsion strength. V-belt should be replaced
when the belt is worn or broken.
Make sure to disconnect electrical power
to the drill press to avoid the possibility of
inadvertent operation and exposure to
potentially lethal voltage levels.
1. Open the machine head cover.
2. Loosen lock lever to free the motor.
3. Slide the motor toward the pulley.
4. Lift out or remove the V-belt.
5. Replace the belt.
6. Use tension lever on the motor to slide
motor away to tension the belt.
7. Tension should be loose enough to allow
5-10mm movement when pushing the belt
from the side.
8. Tighten the lock lever to secure the motor
in place.
9. Install the cover.
