BATTERY CHARGING USING A GENERATOR
The charger can only be connected to a generator fitted with a full AVR (Automatic voltage regulator)
and spike filtering system. Large voltage fluctuations and spikes will damage the electronic compo
-
nents in the charger. It has been noted that the Honda generator set offers the best and most reliable
voltage supply. This applies only to the fully integrated Honda generator sets and not the cheaper
options using a Honda engine fitted with a non-Honda generator unit.
EMERGENCY STOP
Two emergency stops are fitted; one at the lower controls and the other at the upper controls. When
pressed down on, they must stop all movements immediately. To release, pull up the emergency stop.
The switch head is not physically attached to the switch mechanism behind the head. If the head is
released and the machine will not start, check that the switch has not seized in the off position.
ELECTRICAL SYSTEM
The electrical system is quite simple and requires minimal maintenance. The biggest problem is
loose connections which is caused by vibration during towing and secondly moisture or condensa-
tion caused by high humidity and temperature fluctuations.
Erratic running of the motor when pressing down on the platform raise/lower button and moving the
booms can be caused by an intermittent internal cable failure. The failure can be hard to locate. The
best way is to lower the relevant boom. If the motor has stopped permanently, use the emergency
lower system. Try raising the boom again to determine if the fault occurs roughly in the same place. If
it does, it is highly likely there is an internal cable failure and the complete cable should be replaced.
On mains powered machines, the control circuit is almost identical apart from voltage variants and
the use of an isolation transformer on the control circuit. The bolt on motor contactor used on the
DC pack is replaced by a combined thermal overload and motor contactor mounted inside its own
junction box. On engine powered machines, the boom circuit is the same as for the DC powered
machines apart from the electrical start/stop circuit needed for the engine.
OUTRIGGER SAFETY & MAINTENANCE
•
It should not be possible to raise the outriggers with the booms up in the air. If this occurs, im-
mediately check the boom limit switch and the diverter valve. If it is not possible to lift up the
outriggers after lowering the booms, check the same components.
•
It should not be possible to lift the booms up in the air unless the outriggers are all down and
in full contact with the ground. If this occurs, adjust the outrigger limit switch immediately. If
lifting is performed without having the outrigger correctly set, the operator will fall over. In any
case of instability, the machine will stop and the audible alarm mounted on the underside of the
platform control box will sound. The hand pump must be used for dropping down and re-setting
the outriggers. Check that the LED on the ground control panel is working correctly. Each LED
should only come on when the outrigger is in contact with the ground.
•
Check that the audible alarm is working. It should sound when the outriggers are unstable.
