2. Safety Instructions

Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury.

General Power Tool Safety

• Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents.
• Electrical Safety: Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Personal Safety: Always wear appropriate personal protective equipment, including safety glasses, hearing protection, and gloves. Dress properly; avoid loose clothing or jewelry that can get caught in moving parts.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

Battery Pack Safety

• Only use the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• 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 burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

4. Setup

4.1 Battery Charging

1. Connect the charger to a power outlet.
2. Insert the 21V Lithium Battery into the charger.
3. The charging light on the charger will illuminate, indicating that charging is in progress.
4. Upon completion of charging, the internal electronic switch will automatically activate to prevent overcharging.

5. Operating Instructions

The SASKATE 21V Cordless Electric Impact Wrench is designed for high-efficiency fastening and dismantling operations.

• Power On/Off: The tool is activated by pressing the trigger switch. Release the trigger to turn off the tool.
• Variable Speed Control: The trigger switch provides variable speed control. Pressing the trigger further increases the rotational speed and impact frequency.
• Direction of Rotation: Use the forward/reverse selector switch (typically located above the trigger) to choose between forward (tightening) and reverse (loosening) rotation. Ensure the tool has come to a complete stop before changing the direction of rotation.
• Application: Apply the appropriate drill bit or socket for the task. Position the tool firmly against the fastener or workpiece. Engage the trigger to begin operation. The tool's strong torsion output and high impact frequency (0-3200Hz) will facilitate quick completion of tasks.
