Safety precautions at site
WARNING!
•
Always check that the equipment is in faultless condition and that all
functions are in order before work is commenced.
•
No mounting, for instance change of drill bit, may be performed on the
drill rig unless it is disconnected electrically from the mains.
•
Safety regulations at the work place must be followed as well as the
safety regulations of the operator’s manual for the drill motor used.
•
All persons working with, or in the proximity to the drilling rig should wear
safety equipment, i.e. protection helmet, protection shoes, gloves, eye
and ear protectors. Other safety regulations at the work place must be
followed. The noise level at drilling might lead to permanent hearing
disorders if not ear guards are worn.
•
The operator should have good supervision over the drill system and
inform passing persons about possible risks.
•
Unauthorized persons shall not be within the risk area (the area around
the drill unit).
•
The drill bit may not be touched when the drill motor is in operation.
•
Never connect the hydraulic hoses to either drill unit or power pack while
the power pack is running. The power pack must be disconnected from
the power supply by removing the 32 or 63 Amp plug and cable from the
power pack before any connections are made.
•
The power pack must always be switched off and the 32/63 Amp plug
and cable disconnected from the power pack before any kind of service
is commenced.
•
Mounting and dismounting of the drilling unit and drill bit may only take
place when the drill motor is disconnected from the power pack by
removing the 400V power cable.
•
The power pack is water cooled and must be drained from water when
the ambient temperature is in the proximity of or below 0 degrees
Celsius.
•
The electric motor of the power pack is water cooled and the water
pressure must therefore be limited to max 5 bar. The incoming water
supply may only be connected to the lower connection on the power
pack. The quick disconnect couplings may not be replaced with
couplings that are not fully open when disconnected.
•
Always lift the drill unit ergonomically correct. The Pentpak is not
provided with hooks for lifting. Should this unit need to be lifted with a
crane, this should only be done after permission and instructions have
been given by a person responsible for safety on the site. Contact your
sales agent for instructions on how the lifting can be done in the best
way.
•
The base plate must always be securely anchored to perform safe
drilling.
•
Never run the drill unit without water cooling. The seals are quickly worn
and water leak can occur. Should the cooling water seize to function,
stop the machine immediately.
•
Before drilling is commenced all persons involved must know how the
emergency stop button is working.
•
Remember always to cover drilled holes so that no person falls down
and hurts himself.
