54 Freedom 38 PPA Service Manual 809010
2 – Routine Maintenance
WARNING!
ELECTRIC SHOCK CAN KILL
Turn OFF the power before removing the cover from the system or from the plasma supply.
In the U.S., use a “lock-out / tag-out” procedure until the service or maintenance work is
complete. In other countries, follow appropriate national or local safety procedures.
Before servicing the engine or generator, turn OFF the system, wait for 30 seconds, then
disconnect the battery’s negative (-) ground cable.
Do not touch live electrical parts! If power is required for servicing, use extreme caution
when working near live electrical circuits. Dangerous voltages exist inside the system that
can cause serious injury or death.
Do not attempt to repair printed circuit boards. Do not cut away or remove any protective
conformal coating from circuit boards. To do so will risk a short circuit between the AC
input circuit and the output circuit and may result in serious injury or death.
HOT PARTS CAN CAUSE SEVERE BURNS
Allow the system’s internal components to cool before servicing.
Do not remove the pressure cap from the radiator while the engine is still hot.
MOVING PARTS CAN CAUSE INJURY
Use extreme caution if you need to work on a running engine.
 Keep hands, clothing, jewelry, and tools away from moving parts.
 Keep your hands away from the engine’s fan.
 Do not wear loose clothing or jewelry that can catch on moving parts.
 Remove safety guards only when necessary. Replace the safety guards as soon
as maintenance is complete.
 Close the service panels when maintenance is complete. Repair or replace the
panels if they are damaged.
NOTICE
STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS
Put on a grounded wrist strap before handling printed circuit boards.
