Pinless Hammer Lightweight 1 Inch Air Impact Wrench For Tire Changing 3000nm

Operation method

1. Select the hexagonal socket according to the size of the pre tightening nut.

2. According to the requirements for tightening or loosening the nut, assemble a ratchet (use a right facing ratchet when tightening the nut, and a left facing ratchet when loosening the nut).

3. Insert the high-pressure and low-pressure rubber hoses with quick connectors into the connection between the wrench and the directional valve (high-pressure 1/4 ", low-pressure 3/8"), and after inserting them into place, rotate the outer sleeve of the quick connector by an angle to lock it tightly.

4. The reaction rod should rely on the corresponding hexagonal support sleeve or other places that can withstand the reaction force.

5. The size of the wrench connecting rod angle should be controlled within the calibrated angle range of the reaction rod.

6. When pressurizing, the air release valve should be rotated one turn to the left, opened, and closed after the air is completely discharged.

7. When manually pumping, rotate the reversing valve handle according to the extension and contraction of the hydraulic cylinder piston rod. When the handle is in the left position, the piston rod will extend, otherwise it will retract, and in the middle position, the pressure will be zero.

8. When pressing, the torque value can be obtained by observing the reading value (MPa) on the pressure gauge. The pressure value (MPa) at the required torque value (N.m) should be calculated in advance according to the formula given in Table 2.

9. After pre tightening, place the handle of the directional valve in the middle position to return its pressure to zero.

10. When removing the high and low pressure rubber hoses with quick connectors, the outer sleeve of the quick connector should be rotated by an angle first, so that its notch aligns with the limit pin and is pushed forward to pull out the connector
