CHAPER 10 - SERVICE INSTRUCTIONS
10.3 OTHER ELECTRICAL EQUIPMENT
Charging circuit
– Check and tighten connections regularly.
– The alternator requires only periodic
attention.
It is important to strictly follow the instructions for
protecting the alternator:
– Do not remove battery cables or any other
connections in the charging circuit while
the engine is running.
– Never start the engine if any wire in the
charging circuit is disconnected or loose.
– Whenever the batteries are charged using
an external source, the earth lead to the
frame must be disconnected from the
battery. When reconnecting batteries,
using jumper leads or a charger, be sure to
identify the correct polarities.
– Always disconnect the batteries when
servicing the electrical equipment of the
Lokotrack.
– Do not cause a short circuit in any part of
the system, nor take a test reading with an
instrument with low internal resistance.
If auxiliary batteries are used to assist engine start,
make sure that:
– batteries have the same voltage
– the correct poles are connected
Starter circuit
Normally the starter circuit requires little attention,
but all components should be kept clean and
electrical connections tight. The batteries are an
essential part of the electrical system and are
required to be kept fully charged, clean and topped
up properly to maintain the acid level. Battery
cables must also be checked for tightness and kept
clean and greased.
10.4 WELDING
If any welding is to be done on the machine, care
must be taken to protect sensitive electrical
equipment.
– Stop the engine.
– Turn the main switch OFF.
– Disconnect the earth lead to the batteries.
– Fasten the earth cable of the welding
apparatus as close to the part to be welded,
as possible and make sure that no welding
current is able to pass through any
bearings or electrical equipment.
10.5 PRESSURE ACCUMULATOR
NOTE:
Before removing / repairing any
components from the hydraulic setting control
circuit release the pre-charge pressure by opening
the SHUT off VALVE. Make sure that the pressure
gauge above accumulator indicates NO pressure.
Make sure that the security valve of the gauge is
open.
