for important advice on the drilling procedure.
WARNING! Danger of life!
To drill in to a power line can be lethal. The drill motor can be energized. A circuit breaker will not
protect against this hazard.
WARNING! Danger of life!
If there is a possibility that Drill CORES may fall causing injury or damage to persons or property
then they must be secured before starting work. The risk area must be roped off and a
responsible person left in charge, in a safe place, to prevent entry of unauthorized persons
!
Important!
•
Don’t use a ratchet for feed as it cannot be used in both directions. Feed the machine per
hand. Don’t use any lever or extension to get a higher feed power.
•
If material should get stuck between the drill bit and the wall of the drill hole, shut off the drill
motor and try to remove the bit.
•
Remember to cover drilled holes.
•
If the drill core should get stuck in the drill bit when removing it, increase the water flow if
possible and tap lightly on the drill bit until the drill core gets loose.
•
Never leave the drill core in the drill bit when taking the drill bit out after drilling a hole in a
wall. The drill core can weigh a lot and make the drill spindle break and the drill column fall
down due to overload of the pivoting head and its couplings. First remove the drill bit from
the drill spindle then remove the drill bit with the drill core from the wall using a crane or other
device.
•
Inspect the drill bit before drilling is commenced to see if the drill bit runs true or if segments
are missing. Never use a defective drill bit!
c. Press the Motor ON/OFF button to start the
spindle.
d. When using the CER-M3-MD1 carriage, put the
latch in neutral position to be able to move the drill
motor both downwards and upwards.
