Assembly; Installation; Lubrication; Operating Test - AA-drill 77300 Manuel D'instructions

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.
Slide bars: remove motor belt and push cam handle towards the motor. Oil right
and left slide bars lightly every 2 months. Grease table bracket if cranking
becomes difficult.

7.0 OPERATING TEST

a. Open the belt cover and release the left & right side cam shaft set handle. Then
move the belt handle backward until the belt has its right tension.
b. The rotation speed of spindle shaft can be charged by refering to the chart list
which is attached inside the belt cover, then you can push the belt handle to
adjust the V-belt to its right tension and set back the two sides cam shaft set
handle.
c. Plug the electric socket to the outlet and press "ON" the switch. Then the
spindle shaft will rotate clockwise.
d. If the spindle shaft rotates counter-clockwise, it means the wiring connection is
wrong, so turn off the switch and change the connection, after changing the
spindle shaft will rotate clockwise.
