Engine
Before the engine is started, perform the required
daily maintenance and any other periodic
maintenance that is due. Refer to the Operation and
Maintenance Manual, "Maintenance Interval
Schedule" for more information.
• For the maximum service life of the engine, make
a thorough inspection within the engine
compartment before the engine is started. Look for
the following items: oil leaks, coolant leaks, loose
bolts, and excessive dirt and/or grease. Remove
any excess dirt and/or grease buildup. Repair any
faults that were identified during the inspection.
• Inspect the cooling system hoses for cracks and
for loose clamps.
• Inspect the alternator and accessory drive belts for
cracks, breaks, and other damage.
• Inspect the wiring for loose connections and for
worn wires or frayed wires.
• Open the fuel supply valve (if equipped).
• 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.
• Ensure that the areas around the rotating parts are
clear.
• All of the guards must be put in place. Check for
damaged guards or for missing guards. Repair
any damaged guards. Replace damaged guards
and/or missing guards.
• Check electrical cables and check the battery for
poor connections and for corrosion.
• Reset all of the shutoffs or alarm components (if
equipped).
• Check the engine lubrication oil level. Maintain the
oil level between the "Min" mark and the "Max"
mark on the engine oil level gauge.
• Check the coolant level. Observe the coolant level
in the header tank (if equipped). Maintain the
coolant level to the "FULL" mark on the header

tank.
• Observe the air cleaner service indicator. Service
the air cleaner when the diaphragm enters the red
zone, or when the red piston locks in the visible
position.
• Remove any electrical loads.
Prime the Oil System
Note: Always perform the general checks before
priming the oil system.
• If the engine has not been started for 3 months,
rebuilt, or the engine oil and filter has been
changed, then the oil system must be primed.
• Ensure that the gas supply is in the closed
position. Refer to the Original Equipment
Manufacturer (OEM) for more information.
• Turn the keyswitch to the START position. Hold
the keyswitch in this position until the oil pressure
gauge indicates 300 kPa (43.5 psi). Continue to
hold the keyswitch in the START position for an
extra 10 seconds.
• Only crank the engine for 30 seconds when
building engine oil pressure. After 30 seconds,
stop cranking and allow 2 minutes for the starter to
cool.
• When oil system is primed, open the gas supply
valve, then refer to this Operation and
Maintenance Manual, Starting the Engine
Cold Weather Starting
A jacket water heater is required for starting when the
temperature is below 10 °C (50 °F). The temperature
of the jacket water should be maintained at 40 °C
(104 °F).
Note: A oil pan immersion heater must not be
installed.
The 4016-61TRS engine is equipped with Multitorch
spark plugs. Under certain circumstances, it is
possible for condensation to develop within the
nozzle for the spark plug. This may cause difficulty in
engine starting. If this occurs, conduct the following
procedure:
