CAPACITOR DISCHARGE
WARNING
Discharge the capacitor bank prior to
performing any service on the lift truck.
Failure to follow proper discharging
procedures can result in personal injury or
damage to the electronic circuitry of the truck.
The normal method of discharging the capacitors
is:
1. Turn the key switch OFF (Position '0').
2. Disconnect the battery.
3. Turn the key switch ON (Position 'I'). The
operator display will light then slowly dim.
Once the operator display goes black, the
capacitors are fully discharged.
4. Turn the key switch OFF.
The above method cannot be used if the 15 amp
fuse for the System Controller is open. In this
event, the capacitors can be discharged by the
following method:
1. Turn the key switch OFF.
2. Disconnect the battery.
3. Use an INSULATED electrical cable or
wire to short the Positive and Negative
bus bars at the capacitors.
