English OPERATION WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury. Installing and Removing the Battery Pack (Fig. G) NOTE: For best results, make sure your battery pack is fully charged. To install the battery pack 6 into the tool handle, align the battery pack with the rails inside the tool's handle and slide it into the handle until the battery pack is firmly seated in the tool and ensure that it does not disengage. To remove the battery pack from the tool, press the release button 5 and firmly pull the battery pack out of the tool handle. Insert it into the charger as described in the charger section of this manual. Fig. G 6 5 Proper Hand Position (Fig. H) WARNING: To reduce the risk of serious personal injury,  ALWAYS use proper hand position as shown. WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction. Proper hand position requires one hand on the main handle 4 . Fig. H 4 Usage Your impact tool can generate the following maximum torque values. NOTE: Output torque is dependent on the speed selected, with the highest provided in Speed 3. 10 Ft.-Lbs. Nm Cat # Low/High/ Precision Wrench™ Low/High/ Precision Wrench™ DCF894, DCF894H 0-150/0-330/0-330 200/447/447 CAUTION: Ensure fastener and/or system will withstand the level of torque generated by the tool. Excessive torque may cause breakage and possible personal injury. 1. Place the accessory on the fastener head. Keep the tool pointed straight at the fastener. 2. Press switch to start operation. Release switch to stop operation. Always check torque with a torque wrench, as the fastening torque is affected by many factors including the following: ʵʵ Voltage: Low voltage, due to a nearly discharged battery, will reduce fastening torque. ʵʵ Accessory size: Failure to use the correct accessory size will cause a reduction in fastening torque. ʵʵ Bolt size: Larger bolt diameters generally require higher fastening torque. Fastening torque will also vary according to length, grade, and torque coefficient. ʵʵ Bolt: Ensure that all threads are free of rust and other debris to allow proper fastening torque. ʵʵ Material: The type of material and surface finish of the material will affect fastening torque. ʵʵ Fastening time: Longer fasteni­ng time results in increased fastening torque. Using a longer fastening time than recomm­ ended could cause the fasteners to be overstressed, stripped or damaged. MAINTENANCE WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury. Cleaning WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing this.
