Starting the drill system
All preparations above should be finished before starting the machine. The starting sequence
is described below.
1.
Make sure
that the drill bit runs true and is not damaged, for instance that no
segment is missing.
2.
Make sure
that correct RPM is used for the drill bit diameter.
3.
Checks if something is embedded in the concrete, for instance re-bars, and
adjust
the drilling thereafter.
4.
Check
that the lever on the hydraulic motor is in the OFF position.
5.
Check
oil level in the power pack.
6.
Check
that the potentiometer on the power pack is in it is OFF (max CCW)
position.
7.
Check
that the cooling water to the power pack is on and that water feeds to the
drill bit through the spindle unit.
8.
Check
that there is enough power to the power pack.
9.
Start the power pack
: Push the”Start/Stop power pack” on the remote control.
Start the power pack during ca. 10 seconds and then stop it again. Check the oil
level and fill up if needed. See “oil level”.
10.
Starting operation of the drill unit:
To start the operation of the drill unit, press
the Start/Stop button for operation of the drill unit and keep it pressed, then press
the El. Motor button once.
11.
Start drill bit:
Pull the lever on the hydraulic motor to
ON
. A”slow start”, i.e.
slowly pulling the lever until the drill bit starts rotating, can be used. This
facilitates making the first groove in the concrete.
12.
Start feeding:
When using the hydraulic feed unit, turn the knob”Feed movement
on the column” on the remote control to the left or right to move the carriage
either upwards or downwards on the column.
13.
Adjust the feeding speed:
When using the hydraulic feed unit, turn the
potentiometer until a smooth drilling pace is reached.
Important!
Do not increase the feeding speed of the drill bit when drilling in re-
bars. Decrease the speedf instead until the re-bars are drilled through.
14.
Gear change:
Shut off the operation of the drill unit with the remote control. Turn
the lever on the hydraulic motor to
OFF
. If the operator does not have overview of
the power pack, it should be shut off and the hydraulic hoses should be
