Operation
4.1
CONTROL CIRCUIT COMPONENTS
4.1.1
KLAXON: -
Mounted on the power control box is a klaxon which is interlocked into the stabiliser control
circuit. It is this device that sounds continuously if a jack goes light in operation, with the booms
raised, warning the operator of this condition. It will also sound if the Ground Control Key switch is
turned to Basket position before the outriggers are deployed.
4.1.2
BOOM-SWITCH (TM34H ONLY): -
Mounted on the side of Boom 1 near the boom rest and operated
by contact with the boom 3, this switch controls the changeover function between outriggers and
basket. The outrigger control function is not available unless this switch is engaged with the boom,
ensuring that the machine must be stowed to operate the hydraulic outriggers. It is also similarly linked
into the basket control circuit, such that if the switch is not engaged with the booms, (i.e. machine is in
operation) then the outrigger sensors are active and would warn the operator of an unsafe condition,
should one of them loose contact with the ground. These control functions are of primary importance
to safety of the machine and operator. Under no circumstances should this control function be isolated
or by-passed.
4.1.3
BATTERY ISOLATOR: -
A red battery isolator handle is located on the power tray which allows the
machine control and power circuits to be isolated from the battery. Under normal operation, the
machine Key switch should be used to isolate the machine with the Battery Isolator only being required
to disconnect the batteries for maintenance or in the event of a short circuit. The battery charging
circuit is connected directly to the battery side, so charging is un-affected by use of this switch.
4.1.4
POWER SOURCE SELECTION (TM34H ONLY):-
On multiple power option machines, the machine is
fitted with an ‘instinctive’ circuit for power source selection. Pressing the green button will
automatically select battery operation. The engine can be started using the two position START/STOP
selector in the basket and the machine will ‘default’ to engine operation via a flow switch in the
hydraulic circuit. Stopping the engine by selecting STOP on the two position selector in the basket and
pressing the green button will return the machine to battery mode.
4.1.5
DIESEL ENGINE: -
Generally a Yanmar L40 or Kubota 0C60 engine, described in the maintenance
section of the Workshop Manual, driving a single bodied pump with direct mounted pump dump valve.
4.1.6
GASOLINE ENGINE: -
Generally a Honda GX 160 engine, described in the maintenance section of the
Workshop Manual, driving a single body pump with direct mounted pump dump valve.
