Correct Drilling Speeds; Drilling Wood; Drilling Operation; Changing Motor Voltage - Craftsman 152.229010 Instruction Manual

CORRECT DRiLLiNG SPEEDS
Factors that determine the correct speed are: the work-
piece, the size of the hob, the type of bit or other cutter,
and the quality of cut wanted,
Use the recommended speed for the ddH bit and work-
piece.
DRiLLiNG WOOD
Tvqst drill bits, usually intended for metai drHHng, can
abo be used for boring hobs in wood. However, brad
point or Forstner bits are generally preferred for working
in wood. These bits cut a fiat bottom hob and are
designed for removai of wood chips. Do not use hand
bits which have a screw tip or auger bits. At drill press
speeds, they will Hft and rotate the workpiece.
For through boring, align the table so that the bit will go
through the center hole. Scribe a vertical line on the
front of the column and a matching mark on the table
bracket and the drill press head, so that the table and
drill press head can be clamped in the center position
at any height.
Feed the bit slowly when it is close to cutting through
the wood to prevent splintering the bottom face. Use a
scrap piece of wood as backup under the workpiece.
This helps to reduce splintering and protects the point
of the bit.
DRULUNG METAL,
ALUMINUM OR BRASS
NEVER hold the workpiece in your bare hands,
ALWAYS use clamps or vises to hold your workpuece,
Twist drill bits should only be used in drilling metals,
Never hold the workpiece in your bare hands; always
use clamps or vises, The drill bit may seize the work at
any time, especially when breaking through the work-
piece, if the workpiece is whirled out of the operator's
hand, the operator may be injured, The drill bit wiii be
broken if the workpiece strikes the column,
The workpiece must be clamped or securely held in a
vise while drilling, Any tilting, twisting, or shifting results
not only in a rough hob, but also increases drill bit
breakage, For fiat work, lay the workpiece on a wooden
base and clamp it firmly down against the table to preo
vent it from turning, if the workpiece is of irregular
shape and cannot be laid fiat on the table, it should be
securely blocked and clamped,
When drilling metal, it wiii be necessary to lubricate the
tip of the drill bit with oil to prevent it from overheating,
DRULUNG OPERATION
Use a center punch to dent the workpiece where you
want the hob. This will keep the bit from walking when
you start the drill operation. Before turning the drill
press ON, turn the laser ON and align the cross-hairs
with center mark on the workpiece. Make sure the
workpiece is properly supported or secured to the table.
For thruodrilling, make sure the table center hob is
aligned with the drill bit. Turn the drill press ON and
start to feed the drill chuck down with the feed handles.
FEEDING TOO RAPIDLY may cause the belt or drill bit
to slip or break, the motor to stall, the workpiece to pull
loose from the table, Never try to rush your work; allow
the drill press to work smoothly,
CHANGmNG MOTOR VOLTAGE
MAKE CERTAIN to disconnected the machine from the
power source before working on motor.
Have a certified electrician make all electrical connec-
tions, All local and state codes must be maintained,
The motor supplied with the Drill Press is a dual voltage
120/240-volt, single phase motor, The motor is wired
from the factory for 120-volt operation, To change to
240-volt operation, proceed with the following instruc-
tions, it is also necessary to replace the 120 volt plug,
supplied with your machine, with a UL/CSA Listed plug
(not included) suitable for 240 volts and the rated cur°
rent of the motor, The motor with a 240 volt plug
should only be connected to an outlet having the same
configuration as the plug, No adapter is available or
should be used with the 240 volt plug,
1, Make sure switch is OFF and disconnect power
cord from power source,
2. Verify on the motor tag that motor is dual voltage.
3. if motor tag states that it is dual voltage remove
junction box cover on motor.
4, Using wiring diagram on inside of junction box
cover, reconnect motor leads for 240-volt operation,
5. Replace junction box cover.
6, Replace 120 volt plug with a UL/CSA Listed 240
volt plug rated for current of the motor,
7. The ON/OFF switch is a 4-pole switch and does not
need any modifications.
