LPG OPERATION: -
On machines equipped for LPG operation (propane), the Honda engine will also
have an LPG vaporiser, valve lock and micro-vac switch. The vapour take-off system requires a
vaporiser to convert the liquid gas into an airborne mixture. This is then held by the micro-vac switch
and valve lock until the engine turns over, creating a vacuum on the inlet to the engine carburettor. The
micro-vac switch then tells the valve lock to open, admitting the gas to the engine. If the engine is
halted, the system returns to normal, holding the gas until a re-start is attempted. When running on
petrol, the main tap to the gas bottle should be securely closed to prevent the engine from trying to run
on a mixture of the two fuels. If starting to run on LPG, it should be ensured that all petrol is
discharged from the carburettor bowl before changing to LPG, since the engine will not run
satisfactorily of any petrol is in the carburettor bowl.
4.1.2 POWER
SELECTION
The Kubota engine, AC power pack, hydraulic reservoir and starter battery are all packaged beneath a
two-piece fibreglass canopy, sandwiched between the two front jacks. Cold-starting the engine (See
section 4.3.1) is permissible from the side of the canopy, and once running, all controls are situated in
the platform.
If the machine is to be used in an enclosed area, or within a domestic setting, the diesel engine can be
switched off and AC power selected. The auxiliary motor is a 1.5 kW single-phase motor (refer to
motor plate for voltage) driving a direct coupled 1,5cc gear pump. This can be manually selected to
provide hydraulic flow to the Booms only.
Once plugged in, the electric motor will run whenever the platform Key switch is turned to the ‘I’
position. If the diesel engine is running, this will stop it. This interlock is there to prevent both power
sources providing hydraulic flow at the same time. When the electric motor is running, hydraulic flow
is available for switching to the Booms. This is achieved by using the same control system described
previously. When directed to the Boom function, speeds are roughly the same as the diesel engine.
NB:
If the diesel engine is needed for movement between work locations, it will be necessary to
remove the mains plug from the socket, to allow the diesel engine to be started.
ALWAYS ALLOW THE ENGINE TO WARM UP BEFORE OPERATING.
