This document describes the Klein Tools BAT20-LW / BAT20-LW1 Right Angle Impact Wrench, a professional power tool designed for impact fastening and applications, particularly useful for installing and removing threaded fasteners. It is powered by a 20V Li-Ion battery and features variable speed control from 0 to 1800 RPM, delivering up to 300 ft-lbs (41.2 kg-m) of torque. The tool is equipped with 1 1/8", 1", 13/16", and 3/4" square drives.
Technical Specifications:
- Power Source: 20V Li-Ion battery
- Speed: Variable, 0 – 1800 RPM
- Torque: Up to 300 ft-lbs (41.2 kg-m)
- Drives: 1 1/8", 1", 13/16", 3/4" Square Drives
Feature Details:
The tool includes several key components:
- Trigger switch (A): Activates the tool.
- Forward/reverse/lock trigger button (B): Controls the direction of rotation and serves as a lock-off button.
- Removable socket (C): For attaching accessories.
- Main handle (D): Provides grip for operation.
- Battery pack (E): The power source for the tool.
- Battery release button (F): Used to remove the battery pack.
- Fuel gauge button (G): Displays the battery charge level.
- Lift ring (H): For moving the tool into difficult-to-reach areas.
- Side warning label (I): Contains important safety information.
- LED (J): Provides illumination.
Usage Features:
- Proper Hand Position: Requires one hand on the main handle (C). Always use proper hand position and hold securely in anticipation of a sudden reaction to reduce the risk of serious personal injury.
- Variable Speed Trigger Switch: Squeeze the trigger switch (A) to turn the tool on; release to turn off. The tool has a brake that stops rotation when the trigger is fully released. Variable speed allows selection of the best speed for specific applications. Continuous use in the variable speed range is not recommended as it may damage the switch.
- Forward/Reverse Button: The forward/reverse control button (B) determines the direction of rotation and acts as a lock-off button. To select forward rotation, release the trigger and depress the button on the right side. For reverse, depress the button on the left side. The center position locks the tool in the off position. Ensure the trigger is released when changing the control button position. A click may be heard on startup after changing rotation direction, which is normal.
- Insert Socket Accessory: Sockets fit into the large socket on the angle impact wrench. To install, insert the socket and press firmly until it clicks into place. To remove, push the release button on the side (D) of the large socket.
- Fastening Torque: Fastening torque is affected by voltage (low voltage reduces torque), accessory size (incorrect size reduces torque), bolt size (larger diameters require higher torque), and bolt condition (threads free of rust/debris allow proper torque). Material type and surface finish also affect torque. Longer fastening time increases torque, but excessive time can over-stress or damage fasteners.
- Lift Ring: The lift ring (H) is for moving the tool into difficult-to-reach areas. Securely fasten a lifting device to the ring before moving the tool. DO NOT use the lift ring for tethering or securing the tool to a person or object during use when elevated.
- Fuel Gauge Battery Packs: Some DeWALT battery packs include a fuel gauge with three green LED lights. Press and hold the fuel gauge button (G) to illuminate the charge level. If the charge is below the usable limit, the gauge will not illuminate, and the battery needs recharging. The fuel gauge is an approximate indication and is subject to variation.
- 75 – 100% charged: All three LEDs illuminated.
- 51 – 74% charged: Two LEDs illuminated.
- <50% charged: One LED illuminated.
- Pack needs to be charged: No LEDs illuminated.
Battery Charging Instructions (for DeWALT chargers):
- Charging Procedure: Plug the charger into an outlet, then insert the battery pack (E). The red light will blink continuously, indicating charging. A solid red light indicates a full charge.
- Charge Indicators: A fast-flashing red light indicates a problem. Re-insert the battery pack; if the problem persists, try a different battery pack. If the new pack charges, the original is defective. If both packs show trouble, the charger may be faulty.
- Hot/Cold Delay: Chargers have a hot/cold delay feature. If the battery is too hot or cold, charging is suspended, indicated by a blinking red light and an illuminated yellow indicator. Charging resumes automatically once the battery reaches an optimum temperature.
- Leaving Battery Pack in Charger: The charger and battery pack can remain connected after charging is complete.
- Weak/Faulty Battery Packs: Weak batteries will function but perform less work. Faulty battery packs will not charge, indicated by the charger refusing to light.
Maintenance Features:
- Service: Have the power tool serviced by a qualified repair person using identical replacement parts to ensure safety. Contact Klein Tools for authorized service centers.
- Charger and Battery Pack: These are NOT user-serviceable. Repairs, maintenance, and adjustments should be performed by a DeWALT factory service center or authorized personnel using identical replacement parts.
- Cleaning:
- Impact Wrench: Blow dirt and dust out of air vents with clean, dry air at least once a week. Always wear ANSI Z87.1 approved eye protection. Do not use solvents or harsh chemicals on non-metallic parts. Use a cloth dampened with water and mild soap. Do not immerse the tool in liquid.
- Charger: Disconnect from the AC outlet before cleaning. Remove dirt and grease from the exterior with a cloth or soft non-metallic brush. Do not use water or cleaning solutions.
- General Warnings:
- DO NOT use under wet conditions or in the presence of flammable liquids or gases.
- This is a professional power tool; DO NOT let children come into contact with it. Supervision is required for inexperienced operators.
- Never modify the power tool or any part of it.
- Work Area Safety: Keep the work area clean, well-lit, and free of clutter. Do not operate in explosive atmospheres. Keep children and bystanders away.
- Electrical Safety: Power tool plugs must match outlets. Never modify plugs. Avoid body contact with earthed surfaces. Do not expose to rain or wet conditions. Do not abuse the cord. Use an extension cord suitable for outdoor use when operating outdoors. Use a GFCI-protected supply in damp locations.
- Personal Safety: Stay alert, use common sense. Do not operate while tired or under the influence of drugs, alcohol, or medication. Use personal protective equipment, including eye protection, dust mask, non-skid shoes, hard hat, and hearing protection. Prevent unintentional starting by ensuring the switch is off before connecting to power or battery. Remove adjusting keys/wrenches before turning on. Do not overreach; maintain proper footing and balance.
- Additional Specific Safety Rules:
- ALWAYS use safety glasses (ANSI Z87.1 / CAN/CSA Z94.3), hearing protection (ANSI S12.6 / S3.19), and respiratory protection (NIOSH/OSHA/MSHA).
- The power tool is not insulated; fasteners contacting a "live" wire can cause electric shock.
- Secure the workpiece with clamps or other practical means.
- Wear safety goggles/eye protection during hammering/drilling operations due to flying chips.
- Accessories and tools get hot; wear gloves.
- Avoid air vents as they may cover moving parts.
- Avoid prolonged use; vibration can be harmful. Use gloves and take frequent rests.
- Dust created by power sanding, sawing, grinding, drilling, and construction activities may contain chemicals known to cause cancer, birth defects, or other reproductive harm (e.g., lead, crystalline silica, arsenic, chromium). Work in well-ventilated areas and use approved safety equipment. Avoid prolonged contact with dust.
