AIR RATCHET WRENCH AIR IMPACT WRENCH

Max. torque output 34N･m Max. torque output 350N･m
Models AR3100 Models AI3120

For attaching and detaching bolts and nuts in narrow places where work such as Ideal for car tire replacement and bolt / nut installation and removal.
automobile maintenance and assembly lines is difficult. A weight of 1.1 kg is achieved with a magnesium alloy hammer case and a special
Slip resistant double molded grip. reinforced resin body.
Stepless output adjustment is possible by the pull condition of the switch. It is equipped with a lightweight and powery pin clutch.
A rotary joint that prevents twisting of the hose. Output adjustment lever with 3 forward rotations and 2 reverse rotations.
Both forward and reverse rotation can be switched. Stepless output adjustment is also possible by the degree of pull of the switch.
In shape that is easy to hold, we adopt soft grip to soften vibration.
A rotary joint that prevents twisting of the hose.

※ Use a compressor with an air tank. The output of the compressor is recommended to be 0.75 kW (1 PS) or more.
※ If the tightening torque is quite specified, we recommended to use a torque wrench together.
※ 1 The maximum air consumption (ntp) indicates the air consumption converted to the standard condition (0 ° C, 1 atm = 0.1MPa).
The maximum air consumption (op) indicates the air consumption under actual operating conditions (20 ° C, 0.62MPa).
※ 2 Adaptation bolt assumes wheel nut for car.
CAUTION
