Craftsman 17090 Owners Manual - Page 2

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 toot. 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: THEAIR SUPPLYSHOULD BE CLEAN, DRYAND PREFERABLYLUBRICATED.FOR BESTRESULTSDRAINTHE MOISTUREFROMYOUR COMPRESSORDALLY. Use Only Impact Sockets & Accessories Only use sockets designated "FOR USE WITH IMPACT WRENCHES." Hand tool sockets can break, creating a hazard from flying pieces. Always check sockets, retainers and drives regularly for wear or damage and replace when necessary.

The Craftsman Model 875.1998300 1/2" Square Drive Impact Wrench is ideal for general assembly, automotive, agricultural and industrial applications. Features • Built-in regulator for power output adjustment. • Pin type clutch for increased power output. • Ring-type socket retainer allows quick socket changes. Specifications Drive size 1/2" Impacts per minute 900 IPM Free speed (No Load 7,500 RPM Ultimate torque 400 ft. tbs. Weight 5.1 Ibs. Overall length 7_/8'' Average air consumption 6.5 CFM Recommended hose size 3/8" I.D. Air inlet 1/4" NPT Maximum Air Pressure 90 PSI WARNING: Some dust created by using power tools contains chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead based paint • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically- treated lumber. , WARNING] Your risk from those 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 specifically 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 toot for service or changing sockets, make sure the air line is shut-off at the compressor. This will prevent the tool from operating if the throttle is accidentty engaged. Installation (See figure 1) This toot is designed to operate at 90 psi. Lower pressure (below 90 psi) will reduce performance of the toot while higher air pressure (over 90 psi) raises the performance of the toot beyond its rated capacity and could cause serious damage to tool and user. Always use clean dry air. Excessive moisture and dirt wilt greatly reduce the life of any air motor. We recommend the installation of an in-line filter-regulator-lubricator as close to the toot as possible. 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. (2)
