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.
9. Operation
The proper tightening torque may vary depending on the type or size of screw/bolt and the material of workpiece to be fastened.
Hold the tool and place the tip of bit on the head of screw. Apply a forward pressure to the tool to make the screwdriver bit not slip off
the screw, and start the tool to begin the operation.
1 ） The longer the impact lasts, the greater the torque is. The maximum value is achieved at about 6-10 s.
2） The higher the speed is, the greater the torque is.
3） The harder the workpiece to be fastened is, the greater the torque is.
4） Be sure to tighten the small screw slowly for a short time. Otherwise the screw will be damaged.
Note:
1 ） Use a screwdriver bit that fits the screw /bolt head.
2） When tightening the screw, it is best to pre-drill a pilot hole.
3） When tightening the M8 or smaller screw, select the appropriate impact force and take care to adjust the pressure applied to the
switch trigger to avoid damage to the screw.
4） Hold the tool and align it with the screw.
5） If the impact force for fastening the screw is too strong or the fastening time is too long, the screw or screwdriver bit tip may
be subjected to excessive pulling, squeezing, pressure and even be damaged. Be sure to perform a test to determine the proper
tightening time of the screw before starting the job.
Tightening torque is affected by many factors as 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） The improperly sized screwdriver bit or sleeve screwdriver bit may reduce the tightening torque.
3） Bolt
Even if the torque coefficient and the bolt level are the same, the tightening torque is different because of the different diameters.
Even if the diameter of bolt is the same, the required tightening torque is different depending on its toque coefficient and its length.
4） The way the tool is held or the material on the bolt will also affect the torque.
5） Operating at low speed will also reduce the tightening torque.
Warning
For the short screwdriver bit, use a magnetic connecting rod （ not included） . When tightening the screw, apply a little
soap or other lubricant to the thread to facilitate the operation.
