Water Valve; Dismantling The Equipment; Wire Cutting - Husqvarna PP 455 E Manual De Instrucciones

Water valve

When the power to the hydraulic unit is disconnected, the
water valve opens so that the cooling system can be drained
prior to transport and to avoid the risk of the cooler and motor
freezing in sub-zero temperatures. The unit can be
transported vertically or horizontally. If the power is cut during
sawing, the water can be turned off by turning the water flow
valve on top of the power unit clockwise to the stop position.
The water flow connected to the hydraulic tool can also be
reduced by turning the water flow valve.

Dismantling the equipment

1 Allow the motor to stop completely.
2 Disconnect the power supply cable before disconnecting
the water hoses.
3 Disconnect the hydraulic hoses.
4 If there is a risk of freezing, drain the water from the oil
cooler by disconnecting both hoses, opening the water
flow valve, and tilting the unit forwards.
IMPORTANT! Always clean all the equipment at the end of
the working day. Do not use a high pressure washer to
clean the machine.
STARTING AND STOPPING

Wire cutting

Before starting
IMPORTANT! Do not connect the two thick hydraulic hoses
to the wire saw before the cable is correctly fitted and
tensioned, and all guards are correctly fitted.
• Before you start the motor, check that:
- The incoming electrical cable has been connected to a fuse
rated at least 25 A.
- The 32 A or 63 A power setting is chosen. If this is not
done, a message in the display will prompt this when the start
button is pushed.
• Assemble the pressure reduction block supplied with the
wire saw on the hydraulic unit according to the instructions
on the block.
• Connect the two smaller hydraulic hoses to the pressure
reduction block. The hoses in the hose assembly marked
with a red disc by the coupling shall be connected to the
hose on the pressure reduction block that is also fitted
with a disc.
• Close the valve on the pressure reduction block by turning
the knob anti-clockwise until it stops and then two turns
back.
