WARNING
WEAR RESPIRATORY PROTECTION
Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-base paints,
• Crystalline Silica from bricks, cement and other masonry products, and
• 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 those dust masks that are specially designed to filter out microscopic particles.

WARNING
WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. Do not operate power tools in explosive atmo­spheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust of fumes. Keep bystanders children, and visitors away while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
A battery operated tool with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of bat tery may create a risk of fire when used with another battery. Use battery operated tool only with specifically de signed battery pack. Use of any other batteries may create a risk of fire.
PERSONAL SAFETY
Stay alert, watch what you are doing and use com­mon sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. Avoid accidental starting. Be sure switch is in off position before inserting battery. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations. Use safety equipment. Always wear eye protec­tion. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

WARNING
TOOL USE AND CARE
-Use clamps or other practical way to secure and support the workplace to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
-Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
-Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
-Disconnect battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tools. Such pre­ventive safety measures reduce the risk of starting the tool accidentally.
-Store idle tools out of reach of children and other untrained persons. Tools are danger ous in the hands of untrained users.
-When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a connec­tion from one terminal to another.
-Shorting the battery terminals together may cause sparks, burns, or a fire.
-Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.
-Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
-Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
SPECIFIC SAFETY RULES:
1. Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
2. Never touch moving parts. Never place your hands, fingers or other body parts near the tool’s moving parts.
3. Never operate without all guards in place. Never operate this tool without all guards or safety features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.
4. Use right tool. Don’t force small tool or attachment to do the job of a heavy-duty tool. Don’t use tool for purpose not intended —for example— don’t use circular saw for cutting tree limbs or logs.
5. Never use a power tool for applications other than those specified. Never use a power tool for applications other than those specified in the Instruction Manual.
6. Handle tool correctly. Operate the tool according to the instructions provided herein. Do not drop or throw the tool. Never allow the tool to be operated by children, individuals unfamiliar with its operation or unauthorized personnel.

4. Disconnect battery charger from the receptacle.
CAUTION: DO NOT PULL THE PLUG OUT OF THE RECEPTACLE BY
PULLING ON THE CORD. MAKE SURE TO GRASP THE PLUG WHEN REMOVING FROM RECEPTACLE TO AVOID DAMAGING CORD.
5. Remove the battery from the battery charger. Supporting the battery charger with hand, pull out the battery from the battery charger:
a. When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging. b. If the battery is recharged when it is warm due to battery use or exposure to sunlight, the pilot lamp may light in green. The battery will not be recharged. In such a case, let the battery cool before charging. c. When the pilot lamp flickers rapidly in red (at 0.2–second intervals), check for and take out any foreign objects in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your JOHN DEERE AUTHORIZED DEALER. d. Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC24YFA is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
REGARDING ELECTRIC DISCHARGE IN CASE OF NEW BATTERIES, ETC
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.
HOW TO MAKE THE BATTERIES PERFORM LONGER
1. Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
2. Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

(Fig. 12)
Operation
OPERATION (CONTINUED):
5. Selecting the socket matched to the bolt: a. Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will not only result in insufficient tightening but also in damage to the socket or nut. b. A worn or deformed hex or square-holed socket will not give an adequate tightness for fitting to the nut or anvil, consequently resulting in loss of tightening torque. c. Pay attention to wear of socket hole, and replace before further wear has developed.
6. Installing a socket (Fig. 13, 14): Align the plunger located in the square part of the anvil with the hole in the hex. socket. Then push the plunger, and mount the hex. socket on the anvil. Check that the plunger is fully engaged in the hole. When removing the socket, reverse the sequence.
7. Removing the socket: Please do the opposite point on the method of installing socket.
8. Confirm that the battery is mounted correctly.
9. Check the rotational direction: The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the bit counterclockwise. (See Fig. 15). (The (L) and (R) marks are engraved on the body.)
(Fig. 13)
(Fig. 14)
CAUTION: THE PUSH BUTTON CAN NOT BE
SWITCHED WHILE THE IMPACT DRIVER IS TURNING. TO SWITCH THE PUSH BUTTON, STOP THE IMPACT DRIVER, THEN SET THE PUSH BUTTON.
10. Switch operation: a. When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops. b. The rotational speed can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.
NOTE: A buzzing noise is produced when the motor is about to rotate; this is only a noise, not a machine failure.
(Fig. 15)
Cordless Impact Wrench Operator's Manual 17
Operation
OPERATION (CONTINUED):
11. Tightening and loosening bolts: A hex socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds.
If the nut is only loosely fitted to the bolt, the bolt may turn wit the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually tighten the bolt and nut to prevent them slipping.
12. Number of bolt tightened possible: Please refer to the table below for the number of bolt tightened possible with one charge.
Bolt used No. of tightening 15/32" x 1-3/4" (M12 x 45) High Tension Bolt Approx. 120
These values may vary slightly, according to surrounding temperature and battery characteristics.
Operation
OPERATION CAUTIONS:
1. Resting the unit after continuous work: After use for continuous bolt-tightening work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.
CAUTION: DO NOT TOUCH THE PROTECTOR, AS IT GETS
VERY HOT DURING CONTINUOUS WORK.
2. Cautions on use of the speed control switch: This switch has a built-in, electronic circuit which steplessly varies the rotation speed. Consequently, when the switch trigger is pulled only slightly (low speed rotation) and the motor is stopped while continuously driving in screws, the components of the electronic circuit parts may overheat and be damaged.
3. Tightening torque: Refer to Fig. 16 for the tightening torque of bolts (according to size), under the conditions shown in Fig. 17. Please use this example as a general reference, as tightening torque will vary according to tightening conditions. Tightening torque varies, depending on the battery’s charge level. Fig. 18 shows an example of the relationship between tightening torque and the number of tightening. As shown, tightening torque gradually weakens with the increase in the number of tightening. In particular, as the torque decreases very close to the complete discharge (“a” margin in graph), the unit’s impact weakens, the number of time impacts declines and tightening torque drops off abruptly. If this occurs, check torque level, then recharge the battery if necessary.
NOTE: If a long striking time is used, screws will be strongly tightened. This may cause the screw to break, or may damage the end of the bit. If the unit is held at an angle to the screw being tightened, the head of the screw may be damaged, or the specified torque may not be transmitted to the screw. Always keep the unit and the screw being tightened in a straight line.
4. Use a tightening time suitable for the screw: The appropriate torque for a screw differs according to the material and size of the screw, and the material being screwed etc., so please use a tightening time suitable for the screw. In particular, if a long tightening time is used in the case of screws smaller than 5/16" (8 mm), there is a danger of the screw breaking, so please confirm the tightening time and the tightening torque beforehand.
5. Work at a tightening torque suitable for the bolt under impact: The optimum tightening torque for nuts or bolts differs with material and size of the nuts or bolts. An excessively large tightening torque for a small bolt may stretch or break the bolt. The tightening torque increases in proportionate to the operation time. Use the correct operating time for the bolt.
6. Holding the tool: Hold the impact wrench firmly with both hands. In this case hold the wrench in line with the bolt. It is not necessary to push the wrench very hard. Hold the wrench with a force just sufficient to counteract the impact force.

7. Confirm the tightening torque: The following factors contribute to a reduction of the tightening torque. So confirm the actual tightening torque needed by screwing up some bolts before the job with a hand torque wrench. Factors affecting the tightening torque are as follows. a. Voltage: When the discharge margin is reached, voltage decreases and tightening torque is lowered. b. Operating time: The tightening torque increases when the operating time increases. But the tightening torque does not increase above a certain value even if the tool is driven for a long time. (See Fig. 16) c. Diameter of bolt: The tightening torque differs with the diameter of the bolt as shown in Fig. 16. Generally a larger diameter bolt requires larger tightening torque. d. Tightening conditions: The tightening torque differs according to the torque ratio; class, and length of bolts even when bolts with the same size threads are used. The tightening torque also differs according to the condition of the surface of workplace through which the bolts are to be tightened. When the bolt and nut turn together, torque is greatly reduced. e. Using optional parts: The tightening torque is reduced a little when an extension bar, universal joint or long sockets are used. f. Clearance of the socket: A worn or deformed hex or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Using an improper socket which does not match to the bolt will result in an insufficient tightening torque. g. Tightening torque varies, depending on the battery’s charge level Fig. 18 shows an example of the relationship between tightening torque and the number of tightenings. As shown, tightening torque gradually weakens with the increase in the number of tightenings. In particular, as the torque decreases very close to the complete discharge (“a” margin in graph), the unit’s impact weakens, the number of time impacts declines and tightening torque drops off abruptly. If this occurs, check torque level, then recharge the battery if necessary.

Maintenance and Inspection
MAINTENANCE AND INSPECTION:
CAUTION: PULL OUT BATTERY BEFORE DOING ANY INSPECTION OR MAINTENANCE.
1. Checking the condition of the socket: A worn or deformed hex or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of a socket holes periodically, and replace with a new one if needed.
2. Check the Screws: Loose screws are dangerous. Regularly inspect them and make sure they are tight.
CAUTION: USING THIS POWER TOOL WITH LOOSENED SCREWS IS EXTREMELY DANGEROUS.
3. Maintenance of the motor: The motor unit winding is the very “heart” of the power tool.
Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 19): The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
NOTE: When replacing the carbon brush with a new one, be sure to use the JOHN DEERE Carbon Brush Code No. 999054.
5. Replacing carbon brushes: Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 21.
When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in Fig. 22. Lastly, install the brush cap.

Maintenance and Inspection
MAINTENANCE AND INSPECTION (CONTINUED):
CAUTION: BE ABSOLUTELY SURE TO INSERT THE NAIL OF THE CARBON BRUSH INTO THE CONTACT PORTION OUTSIDE THE BRUSH TUBE. (YOU CAN INSERT WHICHEVER ONE OF THE TWO NAILS PROVIDED.)
CAUTION: MUST BE EXERCISED SINCE ANY ERROR IN THIS OPERA­ TION CAN RESULT IN THE DEFORMED NAIL OF THE CARBON BRUSH AND MAY CAUSE MOTOR TROUBLE AT AN EARLY STAGE.
6. Check for Dust: Dust may be removed with a soft cloth or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.
7. Disposal of the exhausted battery:
WARNING: DO NOT DISPOSE OF THE EXHAUSTED BATTERY. THE
