Product questions and answers
Is the D-grip permanently built into the impact body?
The description identifies an auxiliary D-grip attached with four bolts and a supplied hex wrench. Follow the model's assembly instructions.
Is 1,800 ft-lb a forward tightening setting?
No. It is the listed maximum reverse torque. The forward range is 200–1,600 ft-lb and is not a calibrated setting scale.
Can average consumption alone establish compressor suitability?
No. Check full operating demand and delivered airflow at the required pressure for the intended work schedule.
