Grounding instructions:
a. While in use should be grounded to protect user from electric shock.
b. If tools is equipped with approved three-conductor cord and three-prong
grounding plug, it fits a grounding receptacle when using an adapter to
connect a three prong plug to a two prong receptacle. The adapter plug must
be attached to a permanent ground.
Additional safety rules for drill presses:
a. Be sure drill bit or cutting tool is securely locked in the chuck.
b. Be sure chuck key is removed from the chuck before turning on power.
c. Adjust the table or depth stop to avoid drilling into the table.
d. Shut of the power, remove the drill bit or cutting tool, and clean the table
before leaving the machine.
e. Caution when practical. Use clamps or a vise to secure workpiece to keep the
worktpiece from rotating with the drill bit or cutting tool.
Warning: do not wear gloves while operating drill presses!!!
General assembly instructions:
Screw column to base, assemble press head to column and tighten set screw with
hex key. Attach handles chuck etc, upon completion of assembly. Drill press can
be washed with kerosene to remove anti-rust oil applied at factory, then lubricating
oil can be applied.
Round-out tolerance:
For drilling operations require close tolerances, place drill blank in the chuck and
check round-out with a dial indicator. If the round-out is not within desired
tolerance, tap the chuck bottom with a rubber or leather mallet until you get the
desired tolerance.
Operation directions:
The following directions will give the operator not familiar with the drill press
operations a start. Use scrap material for practice to get the feel of the machine
before attempting regular work.
A Correct drilling speeds: Factors which determine the best speed to use in
any drill press operation are based on the material being worked, size of hole, type
of drill or other cutter and quality of cut desired. The smaller the drill, the greater
the required RPM. In soft materials, the speed should be higher than in hard
metals.
B Drilling in metal: Use clamps to hold the work when drilling in metal. The
work should never be held in the bare hand. The lips of the drill may seize the
work at any time especially when breaking through the stock. If the piece is whirled
out of the operator's hand, he may be injured in any case. The drill will be broken
when the work strikes the column.
