DeWalt High Torque Impact Wrench - DCF99MP1T

Precision Wrench mode prevents over-tightening in forward direction and nut run-off in reverse, saving time and preventing damage to fasteners and materials.

Fastening torque (1396Nm) is the maximum torque the tool applies to tighten a fastener. Breakaway torque (1898Nm) is the maximum torque the tool can apply to loosen a tightened fastener.

This tool is designed for DeWalt 18V XR Li-ion batteries. While some older XRP batteries may physically fit, optimal performance and compatibility are ensured with XR models.

Use the 4-mode membrane switch located near the trigger. Each press cycles through different settings, indicated on the switch itself.

While the ergonomic grip is designed for comfort, the tool's weight (2.9kg) may lead to fatigue during extended overhead applications. Using support systems might be beneficial.

The package includes the DeWalt DCF99MP1T Impact Wrench, one 18V 5.0Ah Li-ion battery, one 18V Li-ion battery charger, and a TSTAK compatible carry case.

The LED light features adjustable brightness. Typically, there is a separate control or function associated with the LED for adjusting its intensity, often activated by pressing and holding a specific button or using a dedicated switch.

Ensure the battery is fully charged and properly seated. Check if the battery contacts are clean. Try a different fully charged battery.

The battery may be low on charge. Ensure the selected mode and speed are appropriate for the task. Check for any obstructions or damage to the anvil or socket.

Check if the LED brightness control is set to minimum. If the LED is damaged, contact DeWalt service.

This can indicate a low battery or that the tool is being used beyond its designed capacity. For stubborn fasteners, ensure you are using the correct socket and apply firm, steady pressure.
