In particular, make sure that all three phases carry the correct
voltage (400 V).
Uneven mains voltage (phase unbalance) or interruption.
of a phase (phase failure) result in the motor not starting
and only humming.
Water Connection
If the drill bit is not cooled enough with water, the diamond segments
could heat up and consequently get damaged and weakened. For this
reason, always make sure that the cooling system is not blocked.
In order to supply the machine with water, please proceed as follows:
Connect the tool to the water supply system or a water pressure vessel
using the GARDENA connector.
Always make sure that the machine only runs with enough clear water
as the seals get damaged when the machine is running dry.
Attention! The maximum water pressure should not exceed 3 bar!
Make sure that the segments are well cooled. If the drilling water is
clear, the segments are well cooled.
Overhead-drilling only with water collection ring.
In case of frost warning, drain the water system.
Changing Gears
The PLD 450 AS is equipped with a mechanical 3-speed oil-bath gearbox.
Select the speed according to the drilling diameter (ref. to the tool's
identification plate).
Use the speed selection to change to the next higher or lower speed until
it locks. Change the speed only when the tool is not running; slightly turn
the working spindle to ease the speed change.
Warning!
!
Never apply force and change the gear only when the
machine is running down.
Never use tools, such as hammers or pliers to change
the gear.
Drill Bit Changing
Attention!
The machine is heavy and when you use or sharpen it, it might heat
up enormously. You could burn your hands or get cut or ripped by
the segments. Before the beginning of all works on the tool you have
