3. Precautions before the Start of Maintenance
CAUTION
Damage Hazard: Do not use water or cleaning fluid to clean the
electronic components and control boxes on the engine and the
rail unit. Damage can occur if water or cleaning fluid goes into
these electronic components or control boxes.
CAUTION
Damage Hazard: When electrical welding is done near or on the
engine, electromagnetic fields or peak voltage can occur. This
can cause damage to the electronic components of the Engine
Control System.
Before you do electrical welding, you must do the procedure that follows:
1) Stop the engine.
2) Set to off the electronic system. After one minute, you can continue.
3) If the welding area is in a radius of two meters from an electronic module and/or
a sensor, disconnect the modules and/or sensors.
4) Close the covers of all electronic boxes and apply protection to the cables,
sensors, etc. to prevent damage from sparks and heat.
5) Use a conductive material connected to earth to give protection to the check and
control units.
6) Make sure that the welding cable goes directly to the welding point without
unnecessary loops. Also, make sure that the welding cables are not parallel to
cables of the electronic units.
Before you start the maintenance on the engine, specially the running gear, do the
procedure that follows:
1) Close the shut-off valves on the starting air bottles.
2) Close all the shut-off valves in the control air supply unit.
3) Open the drains on each starting air bottle to release all the pressure.
4) On the starting air shut-off valve, operate the handwheel to move the shut-off
valve to the position CLOSED.
5) On the main starting air pipe, open the vent and drain valve. Keep the vent and
drain valve in the open position until maintenance is completed.
6) On the starting air shut-off valve, open the vent valves. Keep the vent valves in
the open position until maintenance is completed.
7) Open all indicator valves on the cylinder covers. Keep the indicator valves in the
open position until maintenance work is completed.
8) Engage the turning gear and lock the lever. The gear pinion must be in the
engaged position.
Note: If the engine was stopped because the running gear or bearings have
become too hot, do not open the crankcase doors before an elapsed time
of 20 minutes.
Note: During all engine operations (short or usual), the crankcase doors must
be locked with the clamps.
Note: Where carbon dioxide (CO
2
) is used to extinguish a fire in the engine,
there is a risk of suffocation. Make sure that all related spaces have good
airflow to remove all CO
2
gas before
