Warning:
Before starting the machine tool, ensure that the socket has been installed properly.
7.Work light:
Machine is equipped with the work light: when the switch is pressed, the light will come on; when it is released, the light will go out 15s
later.
8.Battery level indication:
When the machine switch is pressed, the battery indicator will stay on for 5s. The remaining capacity of battery pack may be determined
according to the following table.
LED display Remaining battery
0-25%
25-50%
50-75%
75-100%
9.Operation:
Be sure to fully lock the battery pack when the battery pack is inserted, or else it may accidentally fall from the tool and cause personal
injury. Hold the tool firmly, place the socket on the top of the bolt or nut, start the machine tool and start tightening at the proper
tightening time.
The proper tightening torque may vary along with different types or sizes of bolts, and the different workpieces to be tightened.
Generally, the longer the tightening time, the greater the tightening torque.
Note:
Align the tool with the bolt or nut.
Excessive tightening torque may result in damage to the bolt, nut or socket. Before starting work, be sure to carry out a commissioning
trial operation to determine the proper tightening time for the bolt or nut.
If the tool works continuously until the battery pack runs out, it shall be paused for 15 minutes before further operation with a charged
battery pack.
Tightening torque is affected by the following factors. After tightening, be sure to confirm the torque with the torque wrench:
1
）
When the battery is about to run out, the voltage will drop and the tightening torque will reduce.
2
）
Socket:
a
）
Using the wrong size socket will result in a reduction in tightening torque.
b
）
Damaged sockets
（
worn at the hexagonal or rectangular ends
）
will reduce the tightening torque.
3
）
Bolt:
a
）
Even if the torque coefficient and bolt grade are the same, the required tightening torque will be different due to the diameters.
b
）
Even if the diameter of the bolt is the same, the required tightening torque will be different due to the different torque
coefficient, as well as the grade and length of the bolt.
4
）
The use of universal joints or extension bars will reduce the tightening force of the impact socket wrench to some extent, but this
can be compensated by extending the tightening time.
5
）
The holding method of the tool or material of the bolt will also affect the torque.
