SERVICE AND REPAIR
Emergency Lowering Valves
In the event of a power failure, the emergency lowering valve on the ram can be used to lower the
booms.
Emergency Lowering Hand Pump
The emergency hand pump lowering procedure is available from the lower control station.
Guardrails
The guardrails help protect personnel from falling off the platform.
OPERATING SPEEDS AND NOISE LEVEL
Due to oil viscosity and the fluctuating supply of power on a machine fitted with batteries and/or an
engine as its power source, the following nominal operating speeds reached are indicated on table
3-2. All speeds have been taken with fully charged batteries and at an ambient temperature of +10
degrees. Significant speed differences will be experienced if operating in cold climates with batteries
in a semi discharged state or if the engine is poorly maintained. All speeds have been taken from the
platform with 1 person on board.
Note
Mains power powered machines have different speeds.

DUTY CYCLES
The mains power pack and the engine are both continuously rated. The engine speed is fixed and
must not be altered.
BATTERY
With well maintained batteries, you will be able to get the following operations from one full charge in
a simulated working environment. For one cycle, lifting to full elevation and lowering can take place
10 times with a 5 minutes break. The cycle also includes lifting and lowering the outrigger at ground
level once. A total of four cycles can be achieved from one full charge.
This will provide the operator under normal circumstances, a full days work. The charger can also
be connected to the mains supply if re-charging is needed. The machine cannot be run directly from
Table 3-2
: A list of functions and their associated speed times.
