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.

The work must be clamped firmly while drilling any tilting, twisting or shifting results

not only in a rough hole, but also increases drill beakage. For flat work, lay the

piece on a wooden base and clamp it firmly down against the table to prevent from

turning. If the piece is of irregular shape and cannot be laid flat on the table it

should be securely blocked and clamped.

C Boring in wood twist drills:

Although intending for metal drilling may also be

used for boring in wood, machine spur bits are generally preferred for working in

wood. They cut a square bottom hole and are designed for removal of wood chips.

Do not use hand bits which have a screw tip. At drill press speeds they turn into

the wood so rapidly as to lift the work off the table and whirl it.

4. ASSEMBLY

1. Open the box and take out the base and place it on a flat floor.

2. Take out the column with colomn bracket and screw it on the base.

3. Take out the head frame and assemble to the column.

4. Then use the allen key for tightening the set screw.

5. Bring out the handle, then screw it in the round head.

5. INSTALLATION

1. After installing the drill press, use the kerosene to wash out the anti-rust oil

which had been coated in the factory. Then wipe it with lubricant oil.

2. Install your drill press in flat, study floor or surface.

a. Check if the drill press is shaking when the motor is switched “ON”.

b. Check the table bracket if it is moving smoothly up and down.

c. Check if the spindle shaft moves smoothly.

6. LUBRICATION

The ball bearings in the quill and V-belt pulley are grease-scaled for life. Pull quill

down to maximum depth and oil moderately once every 3 months.

7. OPERATING TEST

a. Screw tight the object on the working table while drilling, so as to prevent

injuries and to have a precision workmanship.

b. You can place any size of drill bit you desire in the chuck which is placed below

the spindle shaft.

c. Plug the electric socket to the outlet and press “ON” the switch, then the spindle

shaft will rotate freely.
