Set-up
Securing the Base
The base of the drill press has four mounting holes.
The drill press should be level and rest solidly on the
floor. Place shims under the four mounting holes in
the base as required to level the drill press.
Cleaning
Clean off any protective grease with solvent. After
cleaning, lubricate the base, table, and column with
a light coating of medium weight machine oil.
Repeat at six months intervals.
Internal parts of the drill press are lubricated at the
factory. No further lubrication is required at the time
of installation.
Electrical Connection
Refer to the Wiring Diagram section for wiring
information. Connection to electrical power should
be made by a qualified electrician. Observe local
electrical codes when connecting the machine.
The motor should be protected with a time delay
fuse or circuit breaker with a amperage rating slightly
higher than the full load current of the motor.

adjustment mechanism, the motor must be oper-
