Precautions for the operation of drilling device
1)
When drilling, make sure that the drill head is oriented perpendicular to the
work surface and maintain the able as much as possible at all times. When
drilling, select the appropriate drilling point and make sure that the drill bit is
stable before proceeding.
It is required that the bucket cylinder be
adjusted at all times during operation to
keep the direction of penetration of the
drill tool in a straight line with the drill
tool body.
2)
If there is not enough depth, pull out the
drilling tool first and then restart the
operation.
3)
The tip of the drilling tool attached to
the machine should only be used for
drilling in mud, never on stones.
4)
Avoid pulling out the drilling tool when it is not rotating, as this will bend it.
5)
When drilling, the drilling tool attachment should be vertical to avoid
dislodging the drilling tool, which could damage the adjusting screws.
6)
Never drill the drilling device in a crooked or oblique way.
