•Before the tool isconnectedto the airsupply,the throttle should
bechecked forproperoperation (i.e.,throttlevalve moves freely
and returns to closed position).
• Before removing a tool from service or changing drill bits, make
suretheairlineisshutoffanddrainedofair.Thiswillpreventthe
tool from operating if the throttle is accidently engaged.
•Cuttingtoolsusedwiththesedrillmotorsaresharp.Handlethem
carefully to avoid injury.
• The collet and mandrel must be inserted into a properly sized
pre-drilled hole before starting the tool. An improperly sized pre-
drilled hole prevents the mandrel from engaging the collet and
could result in slippage of the tool. An improperly selected collet
and mandrel can also result in slippage of the tool.
Drilling or other use of this tool may produce hazardous fumes
and/or dust. To avoid adverse health effects utilize adequate
ventilation and/or a respirator. Read the material safety data
sheet of any cutting fluids or materials involved in the drilling
process.
Some non-ferrous metal chips (or dusts) are combustible. Ex-
amples: Aluminum, magnesium, Titanium, and Zirconium. See
the material safety data sheets for combustibility of materials
drilled. Never collect spark generating material with combustible
material. Examples: Collecting both steel and aluminum or steel
and titanium.
Quackenbush drills are often used with lubricant or cooling
systems which must be properly maintained to avoid leakage.
Failure to do so can result in serious injuries from slipping on oily
surfaces.
Foryour safety and the safety of others, read and understand
the safety recommendations and operating instructions be-
fore operating any drill motor.
Always wear protective equipment:
Foradditionalinformationoneyeprotection,readthelatestedition
of ANSI Z87.1, Occupational and Educational Eye and Face
Protection. This standard is available from the American National
Standards Institute, Inc., 11 West 42nd Street, New York, N.Y.
10036.
Hearing protection is recommended in high noise areas (above
85dBA). Close proximity of additional tools, reflective surfaces,
process noises, etc., can contribute substantially to the sound
level experienced by the operator.
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.
Quackenbush drills are designed to operate on 90psig (6.2 bar)
maximum air pressure using the proper hose. Excessive air
pressureincreases the loadsand stresseson toolparts anddrills,
and may result in breakage. The installation of a filter-regulator-
lubricator in the air supply line ahead of the tool is highly recom-
mended.

Due to the number and variety of tooling applications, the user's
methods engineering departments, ect., must consider any haz-
ards that may be associated with each specific application of this
product and provide adequate operator protection from inadvert-
ent contact with any moving components. The clamping and feed
mechanisms of self-colleting drill motors are exposed for visibility
and can move when the air supply is connected or disconnected.
To avoid injury, keep fingers and hands away from these areas
when handling or operating this tool.
Some individuals are susceptible to disorders of the hands and
arms when exposed to vibration and/or tasks which involve
repetitive work motions. Those individuals predisposed to vascu-
latory or circulatory problems may be particularly susceptible.
Cumulativetraumadisorderssuchascarpaltunnelsyndromeand
tendinitis can be caused or aggravated by repetitious, forceful
exertionsof thehands andarms. These disordersdevelop gradu-
ally over periods of weeks, months, and years. Tasks should be
performed in such a manner that the wrists are maintained in a
neutralposition,whichisnotflexed,hyperextended,orturnedside
to side. Stressful postures should be avoided and can be con-
trolled through tool selection and work location.
Safety Recommendations
Any tool operator should be aware of the following warning signs
and symptoms so that a problem can be addressed before it
becomes a debilitating injury. Any user suffering from prolonged
symptoms of tingling, numbness, blanching of fingers, clumsi-
ness or weakened grip, inability to hold objects, nocturnal pain in
the hand, or any other disorder of the shoulders, arms, wrists, or
fingersshould notifytheiremployer sothat areview of whatsteps
might be taken to prevent further occurances. These steps might
include but are not limited to, repositioning the workpiece or
redesigning the workstation, reassigning tool users to other jobs,
rotating jobs, changing worker pace, and/or changing the type of
tool used so as to minimize stress on the operator. Some tasks
may require more than one type of tool to obtain the optimum
operator/ tool/ task relationship.
The following recommendations will help reduce or moderate the
effectsofrepetitiveworkmotions.Theoperatorofanydrillshould:
• Use a minimum hand grip force consistent with
proper control and safe operation
• Keep body and hands warm and dry
• Avoid anything that inhibits blood circulation
— Smoking Tobacco
— Cold Temperatures
— Certain Drugs
• Avoid awkward postures
• Keep wrists as straight as possible
• Interrupt work, activities, or rotate jobs to provide
periods free from repetitive work motions.

Tool Start-Up
The180SC-225 drill isshipped from the factory equipped to
the customer's specifications: spindle RPM, spindle to ac-
commodate cutter type desired, pressure foot type, collet
guide to accommodate collet desired and optional booster
pump (if required).
After unpacking, examine the customer-specified equip-
ment on the 180SC-225 tool to verify type and speed of
components. Attach air line to 3/8-18 NPT inlet bushing. If
quick disconnect fittings are used, 3/8 in. ID are minimum.
The 180SC-225 drill requires a supply of clean 90-100 PSI
air. Air consumption is 45 CFM at 90 PSI. The use of the in-
line lubricator will provide the proper lubrication for the air
motorand willsignificantly increasethe tool life expectancy.
Because O-rings are extensively used to seal systems
within the tool, the elimination of foreign particles and other
contaminants will reduce the possibility of damage to these
parts. Always inspect O-rings for damage or wear and
replace as required. The use of silicone O-ring lubricant is
strongly recommended during reassembly. The addition of
oilintheairlinewillalsoincreasemotorandvalvelifeaswell
asthelifeoftheO-rings.Avoidtheuseofsyntheticlubricants
to prevent damage to O-rings and seals.
