1）Please make sure that the knob is completely set on the required symbols. If the knob is in the halfway position betweenthe
two modes, the tool may be damaged
2）The knob can be rotated after the tool is completely stopped
Torque Limiter:
When a certain torque level is reached, the torque limiter begins to work. The motor will be out of the output shaft. At this point the bit
will stop turning.
Note:
1）Once the torque limiter moves, turn off the tool power switch immediately. This helps prevent the abrasion of the tools
2）The drilling bit, such as a hole saw, is easily clamped or locked in the hole and is not suitable for simultaneous use with the
tool. Because these tools will cause the torque limiter to start too frequently
Installation:
Note:
Before operating on the tool, make sure that turn off the power switch and remove the plug
Install or uninstall a drilling bit:
Before installing the drilling bit, clean the bitand scribble the bit oil.
Insert the bit into the tool, rotate it and push it into the drill until it is occluded.
After installation, be sure to pull the drill outward to confirm that the bit is fixed. When the drill bit is unloaded, pull the chuck shell
downward and pull out the drill bit.

Installation of dust cover:
When it is necessary to drill upward, such as the ceiling, the dust cover can block the falling dust, and the installation position is shown in
the picture.
When using a large drill bit, extend the central hole of the dust cover and install on the drill bit.
Lubrication of tools:
In order to ensure the normal use of tools, please pay attention to the replacement and addition of lubricating oil. If the screw loose
causes oil leakage, please pay attention to timely maintenance. Continuous use of oil leakage will cause tool failure and reduce service
life.
Inspection and maintenance:
When a tool is granted or withdrawn, the storeman must conduct a daily check; before use, users must conduct routine checks.
The daily inspection of tools should include the following items:
1）Whether there are product certification marks and regular inspection of qualified marks.
2）Whether the shell or handle is cracked or broken.
3）Protection of grounding wire （PE）connection is not broken.
4）Whether the power line is intact.
5）Whether the power plug is intact.

8）Whether the rotation part of the tool is flexible, light and free.
9）Whether the electrical protection device is good.
The application of tools must have full-time personnel for regular inspection:
1）Check at least once a day.
2）The inspection cycle should be shortened correspondingly in areas where humidity is hot and temperature changes frequently, or
where conditions are hard.
3）Checked in time before the rainy season.
4）The periodic inspection items of the tool must also measure the insulation resistance of the tool. The insulation resistance shall not
be less than the value specified in Table 1.
Insulation resistance should be measured using 500V megabytes
