The Black & Decker Piranha Saw (Catalog Number PSL12) is a cordless power tool designed for various cutting operations, including trimming branches and cutting metal. It emphasizes user safety through comprehensive guidelines and specific operational instructions.

Function Description

The Piranha Saw is a handheld reciprocating saw powered by a rechargeable Li-Ion battery. Its primary function is to cut through materials using a reciprocating blade. Key functional components include:

Battery (1): Provides power to the tool.
Battery release button (2): Used to remove the battery pack from the tool.
On/off switch (3): Activates and deactivates the saw motor.
Lock-off button (4): A safety feature that prevents unintentional starting; must be pressed before squeezing the on/off switch.
Claw release button (5): Releases the claw mechanism.
Claw stop (6): Limits the rotation of the claw.
Claw (7): A rotating mechanism that comes into contact with the workpiece during operation, helping to stabilize the cut. It rotates forward when the saw is running and retracts to the stop position once the cut is complete.
Blade clamp release lever (8): Used for installing and removing the saw blade.
Shoe (9): The part of the tool that rests against the workpiece, providing stability during cutting.
Charger (10): Used to recharge the battery pack.

Important Technical Specifications

While specific power output (voltage/amperage) for the tool itself is not explicitly detailed, the manual provides crucial information regarding battery charging and extension cord usage for corded appliances (though the Piranha Saw is battery-operated, these guidelines highlight general electrical safety).

Battery Type: Li-Ion battery pack.
Charger Compatibility: Designed to charge Black & Decker battery packs in 3-5 hours.
Charging Temperature Range: Optimal charging occurs between 65°F and 75°F (18°- 24°C). Charging outside +40°F (+4.5°C) and +105°F (+40.5°C) is not recommended to prevent battery damage.
Extension Cord Guidelines (General Safety): For corded tools, the manual provides a detailed table for minimum American Wire Gauge (AWG) based on total cord length and ampere rating (e.g., for 120V, 0-25 feet, 0-6 amps requires 18 AWG; 101-150 feet, 12-16 amps requires 14 AWG). This information, while not directly for the PSL12, underscores the importance of proper electrical setup for any power tool.

Usage Features

The Piranha Saw is designed for ease of use with several features enhancing control and safety:

Battery Installation/Removal: The battery pack slides into the tool until an audible click is heard. Removal involves depressing the battery release buttons and pulling the pack out.
Switch Lock-Off Feature: Prevents accidental starting. Users must press the lock-off button (4) before squeezing the on/off switch (3). The lock-off button can be released once the tool is on.
Claw Mechanism: The rotating claw (7) helps stabilize the tool against the workpiece, improving cutting accuracy and control. It is released by the claw release button (5).
Blade Installation/Removal: Blades are installed by rotating the blade clamp release lever (8), inserting the blade shank fully, and then releasing the lever. Removal follows the same process.
Blade Selection: Users should select blades suitable for the material being cut and ensure the blade extends past the shoe and workpiece thickness to prevent breakage and injury. T-shank and U-shank jig saw blades are compatible.
Trimming Branches: For branch trimming, the tool should run at full speed before cutting, and held firmly to prevent bouncing. Cuts should be made down from the top, starting from the branch tip and working in small sections.
Metal Cutting: For metal, a finer blade (24 teeth per inch) is recommended for ferrous metals and a coarse blade for non-ferrous materials. Thin gauge sheet metals should be clamped to wood for stability. A thin film of oil or coolant (except for aluminum, which should be cut dry) can be used to extend blade life.
Workpiece Stability: Always use clamps or other practical means to secure the workpiece to a stable platform to maintain control.
Overhead Cutting: Extra caution is advised for overhead cutting, paying attention to hidden wires and anticipating falling debris.
Vibration Reduction: Using gloves, taking frequent rest periods, and limiting daily use are recommended to mitigate vibration-induced injuries.
Battery Charge Indicator: A green LED on the charger indicates charging status (flashing during charge, solid when fully charged).

Maintenance Features

Proper maintenance ensures the longevity and safe operation of the Piranha Saw:

Cleaning: The tool should be cleaned with mild soap and a damp cloth. No liquids should enter the tool, and it should never be immersed.
Blade Sharpness: Keeping cutting tools sharp and clean improves performance, reduces strain on the motor, and minimizes injury risk.
Regular Inspection: Periodically check the tool for misalignment, binding, breakage, or any other condition that might affect its operation. Damaged parts should be repaired by an authorized service center.
Battery Care:
- Recharge discharged batteries as soon as possible after use, but avoid fully discharging them for longest battery life.
- Store battery packs in a cool, dry place away from direct sunlight and extreme temperatures.
- Do not incinerate, crush, drop, or damage battery packs.
- Do not store or carry battery packs with metal objects that could short the terminals.
- If battery liquid contacts skin or eyes, flush with water and seek medical attention.
Charger Diagnostics: The charger is equipped with LEDs to indicate problems such as a "bad battery" (red LED flashes) or a "hot/cold pack delay" (red LED flashes while battery normalizes).
Service: Repairs, maintenance, and adjustments should be performed by authorized service centers using identical replacement parts to ensure product safety and reliability. Black & Decker provides a helpline (1-800-544-6986) and website (www.blackanddecker.com) for service center locations and support.
Recycling: The RBRC™ Seal on the Li-Ion battery indicates that Black & Decker covers recycling costs. Users are encouraged to return spent Li-Ion batteries to authorized service centers or retailers for environmentally conscious disposal.
