Before Starting Engine - Perkins 1206E-E70TTA Operation And Maintenance Manual

SEBU8601-04
The high-pressure fuel lines are the fuel lines that are
between the high-pressure fuel pump and the high-
pressure fuel manifold and the fuel lines that are
between the fuel manifold and cylinder head. These
fuel lines are different from fuel lines on other fuel
systems.
The differences are as follows:
• The high-pressure fuel lines are constantly
charged with high pressure while the engine is in
operation and up to 10 minutes after the engine
has stopped.
• The internal pressures of the high-pressure fuel
lines are higher than other types of fuel system.
• The high-pressure fuel lines are formed to shape
and then strengthened by a special process.
Do not step on the high-pressure fuel lines. Do not
deform the high-pressure fuel lines. Do not bend or
strike the high-pressure fuel lines. Deformation or
damage of the high-pressure fuel lines may cause a
point of weakness and potential failure.
Do not check the high-pressure fuel lines with the
engine or the starting motor in operation. After the
engine has stopped, you must wait for 10 minutes to
allow the fuel pressure to be purged from the high-
pressure fuel lines before any service or repair is
performed on the engine fuel lines. The 10 minute
wait will also allow static charge to dissipate from the
low-pressure fuel system.
Do not loosen the high-pressure fuel lines to remove
air from the fuel system. This procedure is not
required.
Visually inspect the high-pressure fuel lines before
the engine is started. This inspection should be
performed each day.
If the engine is inspected whilst in operation, always
use the correct inspection procedure to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, "General hazard Information".
• Inspect the high-pressure fuel lines for damage,
deformation, a nick, a cut, a crease, or a dent.
• Do not operate the engine with a fuel leak. If there
is a leak, do not tighten the connection, to stop the
leak. The connection must only be tightened to the
recommended torque. Refer to Disassembly and
Assembly, "Fuel injection lines - Remove and Fuel
injection lines - Install".
• If the high-pressure fuel lines are torqued correctly
and the high-pressure fuel lines are leaking, the
high-pressure fuel lines must be replaced.
• Ensure that all clips on the high-pressure fuel lines
are in place. Do not operate the engine with clips
that are damaged, missing, or loose.
• Do not attach any other item to the high-pressure
fuel lines.
• Loosened high-pressure fuel lines must be
replaced. High-pressure fuel lines that have been
removed must be replaced. Refer to Disassembly
and assembly manual, "Fuel Injection Lines -
Install".

Before Starting Engine

NOTICE
For initial start-up of a new or rebuilt engine, and for
start-up of an engine that has been serviced, make
provision to shut the engine off should an overspeed
occur. This may be accomplished by shutting off the
air and/or fuel supply to the engine.
Engine exhaust contains products of combustion
which may be harmful to your health. Always
start and operate the engine in a well ventilated
area and, if in an enclosed area, vent the exhaust
to the outside.
Inspect the engine for potential hazards.
Do not start the engine or move any of the controls if
there is a "DO NOT OPERATE" warning tag or similar
warning tag attached to the start switch or to the
controls.
Before starting the engine, ensure that no one is on,
underneath, or close to the engine. Ensure that the
area is free of personnel.
If equipped, ensure that the lighting system for the
engine is suitable for the conditions. Ensure that all
lights work properly, if equipped.
All protective guards and all protective covers must
be installed if the engine must be started in order to
perform service procedures. To help prevent an
accident that is caused by parts in rotation, work
around the parts carefully.
Do not bypass the automatic shutoff circuits. Do not
disable the automatic shutoff circuits. The circuits are
provided in order to help prevent personal injury. The
circuits are also provided in order to help prevent
engine damage.
See the Service Manual for repairs and for
adjustments.
