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.
QUESTION AND ANSWER:
1. Why does the machine not operate after the
switch is pressed?
A reversing yoke is located on the upper part of
switch. It is locked. Turn it to the position where
the rotation is in need, and then press the
button to rotate the machine.
2. Why does the hand drill stop when the screw
has not been tightened?
The machine has low-voltage protection. When
the level of battery pack is too low, the machine
will not work. Please confirm the level of
battery pack.
The machine has temperature protection. When
the battery is working at full load for a long
time, the battery pack will overheat and the
temperature protection system will start to
stop the machine. Cool the machine to normal
temperature before resumption.
