• Quackenbush drills are designed to operate on 90psig (6.2 bar)
air pressure. Excessive air pressure can increase the loads and
stresses on tool parts and drills, and may result in breakage. The
installation of a filter-regulator-lubricator in the air supply line is
highly recommended.
• Before removing a tool from service or changing drill bits, make
sure the air line is shut off and drained of air. This will prevent the
tool from operating if the throttle is accidently engaged.
• Cutting tools used with these Quackenbush drill motors are sharp.
Handle them carefully to avoid injury.
Before mounting any positive feed drill, check the lock screws in the
tooling fixture and drill bushing. Make sure both are in good condition
and securely tightened.
Positive feed drills can exert high torques and high thrust loads. If
failure of the lock screws or drill bushing occurs, the drill may
suddenly spin and back away from the drill fixture.

Hearing protection is recommended in high noise areas, 85 dBA or
greater. The operation of other tools and equipment in the area,
reflective surfaces, process noises and resonant structures can
substantially contribute to and increase the noise level in the area.
For additional information on hearing protection, refer to Federal
OSHA Regulations, 29 Code of Federal Regulations, Section 1910.95,
Occupational Noise Exposure, and American National Standards
Institute, ANSI S12.6, Hearing Protectors.
Follow good machine shop
practices. Rotating shafts and
moving components entangle
and entrap, and may result in
serious injuries. Never wear
long hair, loose-fitting clothes,
gloves, ties, or jewelry when
working with or near a drill of
any type.
