Owner's Manual Pneumatic 3/8" Drive C RATCHET Model No. 875.199320 WARNING: Before operating tool, read this manual and follow all Safety Recommendations Operating Instructions. and Safety Warranty Features & Operation Maintenance EspaSol Distributed www=Sears.corn by Sears, Roebuck and Co., Hoffrnan Estates, IL 60179 FULL ONE YEAR WARRANTY ON CRAFTSMAN AIR-DRIVE TOOLS If this Craftsman tool fails to give complete satisfaction within one year from the date of purchase, RETURN IT TO THE NEAREST SEARS STORE IN THE UNITED STATES, and Sears will repair or replace it free of charge. If this Craftsman tool is used for commercial or rental purposes, this warranty applies for only 90 days from the date of purchase. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. 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: THEAIR SUPPLY SHOULD BE CLEAN, DRYAND PREFERABLY LUBRICATED. FOR BEST RESULTS DRAIN THE MOISTURE FROM YOUR COMPRESSOR DAILY. Use Only Sockets Power Sockets and accessories Distributed by Sears, Roebuck and Co., Dept. 817WA, Hoffman Estates, IL 60179. The Craftsman Model 875.199320 3/8" Drive Ratchet Wrench is designed for applications such as automotive repair, general assembly, transmission teardown and maintenance. Features include a lever throttle for speed control and low profile head for work in close quarters.

Always check sockets, retainers and drives regularly for wear or damage and replace when necessary. 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 sockets, make sure the air line is shut-off at the compressor. This will prevent the tool from operating if the throttle is accidently engaged. [, WARNINGJ Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • • • Lever throttle for ease of operation. 1-1/8" Ratchet head height (without socket) for use in close-quarter applications. Front exhaust directs air away from operator. Installation (See figure 1) This tool is designed to operate at 90 psi. Lower pressure (below 90 psi) will reduce performance of the tool while higher air pressure (over 90 psi) raises the performance of the tool beyond its rated capacity and could cause serious damage to tool and user. Lead from lead based paint crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemicallytreated lumber. 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. 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. 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.

This ratchet is equipped with a lever throttle which ailows the operator to vary the speed. Direction control is located on the back of the ratchet head. Initial tightening and loosening of fasteners should be done manually with ratchet used as a hand tool. Fasteners may then be run on and off with relative ease. Keep socket firmly against work surface when running the ratchet to avoid dislodging the socket from the anvil. Excessive torque leverage above tooI specifications will result in premature gear wear. Air Cornpressor -_ q\\\\X\\\\\\_\\ Lubrication An in-line filter-regulator-lubricator (fig 1) is recommended as it increases tool life and keeps the tool in sustained operation. The in-line lubricator should be regularly checked and filled with air tool oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the tools exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper. Excessive amounts of oil should be avoided. In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should receive a generous amount of lubrication through the air inlet. The tool should be run for approximately 30 seconds to ensure oil has been evenly distributed through out the tool. The tooI should be stored in a clean and dry enviroment Recommended lubricants: Use air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents and an EP (extreme pressure) additive.
