Craftsman 875.19119 Impact Driver User Manual


 
Read Operating Instructions
Please become familiar with all the instructions and
warnings before operating any pneumatic tool.
Always Wear Approved Eye Protection
Impact resistant eye protection should meet or exceed
the standards set forth in ANSI Z87.1, Occupational and
Educational Eye and Face Protection. Look for marking
Z87.1 on your eye protection to ensure that it is an
approved style.
Hearing Protection is Recommended
Hearing protection should be used when the noise level
exposure equals or exceeds an 8 hour time-weighted
average sound level of 85dBA. Process noise, reflective
surfaces, other tools being operated nearby, all add to the
noise level in a given work area. If you are unable to
determine your noise level exposure, we recommend the
use of hearing protection.
Avoid Prolonged Exposure to Vibration
Pneumatic tools can vibrate during use. Prolonged
exposure to vibration or very repetitive hand and arm
movements, can cause injury. Discontinue the use of any
tool if you experience tingling, numbness, discomfort or
pain in your hands or arms. You should consult your
physician before resuming use of tool.
90 PSI Maximum
This tool is designed to operate at an air pressure of 90
pounds per square inch gauge pressure (90 PSI)
maximum, at the tool. Use of higher air pressure can, and
may cause injury. Also, the use of higher air pressure
places the internal components under loads and
stresses they were not designed for, causing premature
tool failure.
NOTE: THE AIR SUPPLY SHOULD BE CLEAN AND DRY,
PREFERABLY LUBRICATED. FOR BEST RESULTS
DRAIN THE MOISTURE FROM YOUR COMPRESSOR
DAIL'_
Use May Produce Flying Objects
Care should be taken when using any percussion tool.
Keep the point of the chisel in contact with the work
surface. Inspect all accessories carefully for damage
before use. Chisels and chisel retainers should be kept
in good condition and replaced as needed. Discard any
accessory that has been damaged to prevent anyone
from using it.
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemi-
cals known to cause cancer, birth defects or reproductive
harm. Some examples of these chemicals are:
Lead from lead-based paint
Cystalline silica from bricks, cement and other
masonry products
Arsenic and chromium from chemically treated
lumber
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals, work in a well-ventilated area and work
with approved safety equipment such as dust masks that
are specially designed to filter out microscopic particles.

Pre-Operation
Before the tool is connected to the air supply, clear the air
hose of accumulated dust and moisture by running air
freely through the air hose for 5-10 seconds. Before
removing a tool for service or changing chisels, make
sure the air line is shut-off at the compressor. This will
prevent the tool from operating if the throttle is accidenfiy
engaged.
Installation (See figure 1)
This tool is designed to operate at 90 psi. Lower pres-
sure (below 90 psi) will reduce performance of the tool
while higher air pressure (over 90 psi) raises the perfor-
mance of the tool beyond its rated capacity and could
cause serious damage to tool and user.
Always use clean dry air. Excessive moisture and dirt will
greatly reduce the life of any air motor. We recommend
the installation of an in-line filter-regulator-lubricator as
close to the tool as possible. (Fig 1)
A 3/8" air hose is required up to a length of 8 ft. If more
length is required a 1/2" air hose should be used at the
compressor. Attach a 3/8" whip hose for the remaining 4 -
8 ft. for flexibility. Be sure all hoses and fittings are the
correct size and tightly secured before using air tool.
