POWER PACK - BATTERY POWER OR MAINS POWER
This is a fully integrated power pack consisting of a motor, pump, relief valve, non-return check valve
and a return filter with a dip stick for checking oil level. The pump is fitted with an internal suction
strainer. The return filter is fitted with a breather and is used for topping up oil if required. The tank is
fitted with a drain plug on the bottom face. A quick release coupling for checking oil pressure is also
fitted on top of the pressure port.
POWER PACK - ENGINE
The engine is fitted with a separate pump which is fitted with a return filter and dipstick. The return
filter is fitted with a breather and is used for topping up oil if required. The tank is fitted with a drain
plug on the bottom face. The relief valve is mounted independently in close proximity to the pump
together with a quick release coupling for checking hydraulic pressure.
The engine is fitted with an electric starter with its own independent starter battery. The engine can
be started from the engine’s start/stop key switch and from the remote start/stop push button from
the platform.
SAFETY SYSTEMS
This is a full fail-safe hydraulic and electric system as required by EN280 and the machinery direc-
tive.
Emergency Stop Buttons
Emergency stop buttons are fitted on the machine
to stop operation in an emergency. There are two
emergency stop buttons; one on the upper control panel and the other on the lower control panel
Note
The lower controls override the upper controls. If the upper control emergency stop button is engaged,
the lower controls can still be used to operate the aerial platform.
Emergency Lowering Switch
The Emergency lowering switch can be used to lower the platform in situations where the boom
levers malfunction.
Note
The emergency lowering switch relies on the electrical system. The switch will not function if the electri-
cal system is faulty.
Outrigger Indicators
The LED lights at the lower control station are indicators for outrigger stability. The outriggers are
pressure sensitive to prevent operating of the booms until the outriggers are in full contact with the
ground. It is not possible to raise the outriggers when the booms are extended.
Emergency Slew
A 17 mm socket together with a lever or spanner may be used to move the platform if there is a
malfunction in the hydraulic or electrical system.
In the event of a failure, the machine can be manually slewed by moving the slew platform clock-
wise or anticlockwise by inserting the slew lever and rotating the gearbox by moving upwards and
downwards.
