MAINTENANCE CD5515-2/YB5515-2 OPERATOR MANUAL
6-30 Published 1-20-2017, Control # 468-02
A reading of less than 10 volts with the engine at low idle
indicates a low battery charge.
A reading of less than 14 volts with the engine speed
above low idle indicates a problem in the charging
system. The system should be checked out by a
qualified service technician.
Charging the Battery
Under normal conditions, the engine’s alternator will have no
problem keeping a charge on the batteries. The only
condition in which the battery(s) may cause a problem is
when they have been completely discharged for a long
period of time. Under this condition the alternator may not be
able to recharge the battery(s) and a battery charger will be
required for charging the battery(s).
Before using a battery charger, an attempt can be made to
recharge the battery using the engine alternator by first jump
starting the crane (See Jump Starting the Engine, page 3-13)
and letting the engine run.
DO NOT charge a frozen battery; it may explode and cause
injury. Let the battery warm up before attaching a charger.
Charging rates between 3 to 50 amperes are satisfactory if
no excessive gassing or spewing of electrolyte occurs or the
battery does not feel excessively warm (over 52°C [125°F]).
If spewing or gasing occurs or temperatures exceed 52°C
(125°F), the charging rate must be reduced or temporarily
stopped to permit cooling.
Replacing the Battery
NOTE: The fluid in electric storage batteries contains
sulfuric acid, which is POISON and can cause
SEVERE CHEMICAL BURNS. Avoid all contact of
fluid with eyes, skin or clothing. Use proper
protective gear when handling batteries. DO NOT
tip any battery beyond a 45° angle in any direction.
If fluid contact does occur, follow the First Aid
suggestions that follows.
Battery Electrolyte First Aid
• External Contact - Flush with water.
• Eyes - Flush with water for at least 15 minutes and get
immediate medical attention.
•Internal - Drink large quantities of water. Follow with
milk of magnesia, beaten egg or vegetable oil. Get
immediate medical attention.
NOTE: In case of internal contact, DO NOT give fluids that
would induce vomiting.
Remove the battery very carefully to avoid spillage of battery
fluid. Properly dispose of the battery.
Fuel System
Fuel Storage
Storage of fuel for an extended period causes accumulation
of sediment, dirt, water and other foreign materials in the
fuel. Many engine problems are caused by dirty fuel and long
storage periods.
Keep fuel in an outside location. Use a shelter to keep the
fuel as cool as possible. The water from condensation must
be removed at regular intervals from the storage tank.
Fuse/Relay Replacement
Fuses and relays are located in two fuse blocks below the
instrument panel (Figure 6-51).
WARNING
FIRE HAZARD
Engine fuel is flammable and can
cause a fire or explosion. Death
or personal injury could occur.
Do not put fuel in tank with engine
running.
Keep open flames away.
Do not use smoking materials during
refueling or servicing.
