The spindle on right angle positive feed drills retracts at a much

faster rate than it feeds. Care should be taken to avoid entrapment.

Nose pieces usually used with these drills are generally slotted for

visibility and access to chuck, cutter, and retract stop adjustments.

A spindle guard should be used when operating tool. Spindle

guards in one inch increments are available to accommodate any

length spindle. Slotted spindle guards are available for tools with

fluid swivels.

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 for any

cutting fluids or materials involved in the drilling process.

• Most dusts are combustible. See material safety data sheets for

combustibility of a specific dust.

• Non ferrous metal dusts are particularly haxardous.

Examples: Aluminum, Magnesium, Titanium, Zirconium

(Never collect Magnesium in a dry dust collector)

• Never collect spark generating material in the same dust collector

with combustible material.

Examples: Collecting both Steel and Aluminum dust or Steel and

Titanium dust.

• Never use flamable finishing lubricants.

Safety Recommendations

Some individuals are susceptible to disorders of the hands and arms

when exposed to tasks which involve repetitive work motions. Those

individuals predisposed to vasculatory or circulatory problems may

be particularly susceptible. Cumulative trauma disorders such as

carpal tunnel syndrome and tendinitis may be caused or aggravated

by repetitious, forceful exertions of the hands and arms. These

disorders develop gradually over periods of weeks, months, and

years.

• Tasks should be performed in such a manner that the wrists

are maintained in a neutral position, which is not flexed,

hyperextended, or turned side to side.

• Stressful postures should be avoided and can be controlled

through tool selection and work location.

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 prolonged symptoms of tin-

gling, numbness, blanching of fingers, clumsiness or weakened

grip, nocturnal pain in the hand, or any other disorder of the

shoulders, arms, wrists, or fingers is advised to consult a physician.

If it is determined that the symptoms are job related or aggravated

by movements and postures dictated by the job design, it may be

necessary for the employer to take steps to prevent further occur-

rences. These steps might include, but are not limited to, reposition-

ing the workpiece or redesigning the workstation, reassigning work-

ers to other jobs, rotating jobs, changing work pace, and/or changing

the type of tool used 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

effects of repetitive work motions. The operator of any drill should:

• 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.
