Portable Two Cycle Gas Engine Impact Wrench 1" Drive | NR11P

Ideal for Railways, Construction Sites, Oil Industries, Mining Industries, and Shipyards.

The fuel tank has a 1.2l capacity for longer working time between refifills. The gripping surfaces on the cap make it easy to remove/replace and the facility to add fuel in both vertical and horizontal positions avoids accidental spillage.

Careful ergonomic design of the machine spreads the weight equally between left and right handles. The structure formed by the combination of the shaped handle bar and the protective shield minimise the risk of accidental mechanical shock to the fuel tank and engine.

Control buttons are specifically located to reduce the effects of working in awkward positions, eg wrist and shoulder discomfort, thereby optimising performance in both vertical and horizontal modes, while a Dead man device prevents accidental acceleration, for operator safety. The control handle assembly is clamped to the handlebar via a steel rod for enhanced robustness.

Brightened steel gears are immersed in a synthetic oil bath to prolong life and extend the range of permitted working temperatures. The gear change lever is adjacent to the accelerator control in order to avoid damage caused by changing gear while the engine is running. Smooth acceleration is provided by the centrifugal clutch.

The innovative patented impact unit develops a high torque and has a larger impact surface than any other nut runner, so to extend the life of this essential component. Specialist, high spec grease minimises wear in this area and the special seal on the drive prevents the leakage of grease commonly seen on other impact wrenches.
