This document is an instruction manual for the Klein Tools 1/4" Impact Driver, models BAT20-CD and BAT20-CD1. It provides general specifications, feature details, safety warnings, operating instructions, maintenance information, and warranty details for the tool, its battery packs, and chargers.
Function Description
The Klein Tools BAT20-CW impact wrench (referred to as an impact driver in the manual's title) is designed for professional impact fastening applications. Its impact function makes it particularly useful for installing and removing threaded fasteners. The tool is powered by a 20V Li-Ion battery, offering cordless operation for enhanced portability and convenience.
Important Technical Specifications
- Power Source: 20V Li-Ion battery
- Chuck Size: 1/4" Hex Quick Connect
- Torque: Up to 210 ft-lbs (29 kg-m)
- Speed: Variable, 0 – 2200 RPM
- Construction: Class II Construction (double insulated)
- Weight: Not explicitly stated, but implied to be manageable for handheld use.
- Compatibility: Designed to work with DeWALT battery packs and chargers.
Usage Features
The impact driver incorporates several features to enhance usability and safety:
- Variable Speed Trigger Switch (A): Allows the user to control the operating speed by squeezing the trigger. Releasing the trigger activates the tool's brake, stopping operation. Continuous use in the variable speed range is not recommended as it may damage the switch.
- Forward/Reverse/Lock Trigger Button (B): This button determines the direction of rotation (forward or reverse) and also serves as a lock-off button.
- To select forward rotation, release the trigger switch and depress the button on the right side of the tool.
- To select reverse rotation, release the trigger switch and depress the button on the left side of the tool.
- The center position locks the tool in the off position, preventing accidental startup.
- Main Handle (C): Designed for a proper and secure hand position during operation.
- Battery Pack (D/E): The tool uses a 20V MAX Li-Ion battery pack.
- Installation: Align the battery pack with the rails inside the tool's handle and slide it in until it is firmly seated and does not disengage.
- Removal: Press the battery release button (F) and firmly pull the battery pack out of the tool handle. After removal, squeezing the trigger for three seconds dissipates any remaining electric charge.
- Fuel Gauge Button (G): Some DeWALT battery packs include a fuel gauge with three green LED lights that indicate the remaining charge level. Pressing and holding this button illuminates the LEDs. If no LEDs illuminate, the battery needs recharging.
- LED Light (H): Provides illumination for the work area.
- Lift Ring (H - also labeled as H in the feature details, but described as a lift ring in operating instructions): Used for moving the tool into difficult-to-reach areas. A lifting device should be securely fastened to the ring before moving the tool. It is explicitly warned NOT to use the lift ring for tethering or securing the tool to a person or object during use when elevated.
- Accessory Use: Only impact-rated accessories should be used to prevent breakage and hazardous conditions. Accessories should be inspected for cracks before use.
- Fastening Torque: The actual fastening torque is influenced by several factors, including battery voltage, accessory size, bolt size, bolt condition, material type, surface finish, and fastening time. Users are advised to always check torque with a torque wrench.
Safety Features and Warnings
The manual emphasizes several safety precautions:
- Work Area Safety: Keep the work area clean, well-lit, and free from explosive atmospheres. Keep children and bystanders away.
- Electrical Safety:
- Power tool plugs must match outlets; never modify plugs.
- Avoid body contact with earthed/grounded surfaces.
- Do not expose power tools to rain or wet conditions.
- Do not abuse the cord; keep it away from heat, oil, sharp edges, and moving parts.
- Use an outdoor-suitable extension cord when operating outdoors.
- Use a GFCI-protected supply in damp locations.
- Personal Safety:
- Stay alert, use common sense, and do not operate while tired or under the influence.
- Always wear personal protective equipment, including eye protection (ANSI Z87.1), hearing protection (ANSI S12.6/S3.19), and respiratory protection (NIOSH/OSHA/MSHA).
- Prevent unintentional starting by ensuring the switch is off before connecting to power or battery pack.
- Remove adjusting keys or wrenches before turning on the power tool.
- Maintain proper footing and balance.
- Dress properly; avoid loose clothing, jewelry, and long hair near moving parts.
- Use dust extraction/collection devices if provided.
- Power tool is not insulated; fasteners contacting a "live" wire can cause electric shock.
- Use clamps or other means to secure workpieces.
- Wear gloves when touching hot accessories/tools.
- Avoid air vents covering moving parts.
- Limit prolonged use due to vibration; use gloves and take rest periods.
- Chemical Exposure Warning: Dust created by power sanding, sawing, grinding, and drilling may contain chemicals known to cause cancer, birth defects, or other reproductive harm (e.g., lead, crystalline silica, arsenic, chromium). Users should work in well-ventilated areas, use approved dust masks, avoid prolonged contact with dust, and wash exposed areas.
- Hearing Protection: Always wear proper hearing protection to prevent hearing loss from product noise.
- Tool Storage: When not in use, place the tool on its side on a stable surface to prevent tripping or falling hazards.
