Warning:
Before starting the machine, make sure that the screwdriver bit is fully fixed by the chuck.
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 display:
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
9.Operation:
Be sure to fully lock the battery pack as it may accidentally fall out of the tool and cause injury to yourself or others. Hold the tool firmly
and place the sleeve above the bolt or nut, turn the machine on and tighten it properly.
The tightening torque may vary depending on the type or size of bolt and the material of workpiece to be fastened. Generally, the longer
the tightening time is, the larger the tightening torque is.
Note:
Align the tool straightly with the bolt or nut.
Excessive tightening torque may damage the bolt nut or sleeve. Before the operation, be sure to conduct the test run to determine the
proper tightening time for the bolt or nut.
If the tool keeps operating until the battery pack is exhausted, the operation shall stop for 15min, and then continue the operation with
the charged battery pack.
Tightening torque depends on the various factors described below. After tightening, be sure to confirm the torque with the torque wrench.
1 ）When the battery pack is about to run out completely, the voltage will drop and the tightening torque will also decrease.
2 ）Sleeve:
a）Incorrectly sized sleeve will result in the decrease of tightening torque.
b）Damaged sleeve （wear of hex end or rectangular end） will reduce the tightening torque.
3）Bolt:
a）Even if the torque coefficient and the bolt level are the same, the tightening torque is different because of the different
diameters.
b） Even if the diameter of bolt is the same, the required tightening torque is different depending on its toque coefficient and its
length.
4）Universal joint or extension rod will reduce the tightening force of the impact sleeve wrench to some extent, which can be
compensated by the extension of tightening time.
5）The way the tool is held or the material on the bolt will also affect the torque.
