7.- MAINTENANCE OF ELECTRICAL GENERATOR
You must make sure that the person who will perform this duty is qualified to do so and utilizes the appropriate
individual protection equipment
.
7.1.- PRIOR TO MAINTENANCE
You must first:
• Switch control module to the STOP position.
• Press the emergency stop button.
• Open the battery isolator.
7.2.- DURING MAINTENANCE
P
reventive maintenance tasks are necessary to preserve the unit; doing so will result in optimum performance.
Be sure to verify the following items:
1) While the engine is cold, the oil level should be between the minimum and maximum values. If it is below the minimum,
add engine oil
.
Note: With the GPM-2 and InteliGen modules, after running 50 hours notice will be given to change the oil. The recommende
oil is 15W40.
2)
radiator water level should be adequate.
3)
T
he fuel level in the tank should be sufficient for the service to be performed. The generator control panel is equipped
with a fuel gauge, which will be functional whenever the electrical panel is receiving power.
4)
A
lways refuel in a well ventilated area with the engine stopped.
5)
Closely inspect the connections and the electrical circuit, for both the mechanical and electrical sections.
6)
Check carefully for possible liquid leaks. If a leak is detected, find its source and resolve the problem.
7)
The air inlet and outlet vents should be completely unobstructed to allow for free circulation of cooling air.
8)
Check the battery’s connection terminals and electrolyte level (if necessary, add demineralized or distilled water). Acid
should never be added. The battery should be recharged if the terminal voltage is below 12.3 V.
9)
If the battery needs recharging after being taken out of the unit, remove the vent caps and charge battery with direct
current only. Connect the charger’s positive (+) cable to the battery’s positive (+) terminal and the charger’s negative (-) cable
to the battery’s negative (-) terminal. Recharge battery with a current equaling 1/10 the nominal capacity (Ah). Battery is fully
charged when acid density is 1.28. Before completing recharging process: turn off charger before disconnecting battery and
check electrolyte level
.
10) If the battery is discharged and you want to perform an emergency startup with the battery from another generator, first
check the tightness of the discharged battery’s terminals. Stop the engines of both units and connect the two positive terminals
of the batteries first and then connect the negative terminal of the charged battery to a metal area on the disabled unit (ground).
Start up the auxiliary unit and then the unit being repaired. Disconnect the cables in reverse order to avoid a short circuit. Finally,
fully charge the battery
.
11)
Installation of the fuel filter in all units means that the operator must constantly monitor the water buildup and drain
as it becomes filled. This does not entail an inconvenience but rather simply keeping an eye on the transparent tank in order to
know when to drain. If the filter were to become worn out, it should be replaced.
12)
The oil draining pump improves the draining process, saves time and facilitates maintenance.
13)
The fuel tank includes a drain hatch to provide quick access and a safety valve to prevent fuel from being extracted
through the outlet on the base fra.
14)
The radiator is drained through the base frame outlet.
15)
For maintaining the canopy, we recommend cleaning periodically to avoid dirt buildup. The unit’s galvanized canopy
prevents corrosion and rust.
Note: While performing preventive maintenance tasks it is advisable to wear protective eyewear and gloves during all
operations involving the handling of battery acid
.
Note: Remember to always perform all operations with the utmost precaution and safety as indicated in this Manual.
(Pay special attention to the risk of short circuits that could be caused by coming in contact with the unit’s metallic objects).
