2.7.2 Operating Procedures when Engine Fails to Start up on First Attempt
When the engine fails to start up even after performing the startup procedures ① to ④ , do not
keep the starter running, but set the starter switch back to ”STOP” and wait about 30 seconds.
Then, repeat the startup procedure once again.
If the repeated procedure does not allow the engine to run, the following causes are suspected.
Check the following:
No fuel
Clogging of fuel filter
Clogging of filter inside the fuel air bleeding electromagnetic pump
Discharge of battery (Low cranking speed)
2.7.3 EFPA (Electrical Fuel Primer and Air Bleed)
If the unit runs out of fuel, the electromagnetic pump attached to the unit will automatically
bleed air out of the fuel system. (After draining sediment from water sedimenter or changing
fuel filter with a new one, bleed the air in the same procedure as below.)
(Procedure)
① Replenish fuel.
② Turn the starter switch to its “RUN” position. The electromagnetic pump starts pumping and
automatically bleed air caught in the fuel pipes.
③ Air-bleeding will be completed within 40 to 50 seconds.
④ Start the machine following the starting procedures mentioned in 2.7.1. If starting fails one time,
repeat the abovementioned procedures.
After finishing the air bleeding operation, never leave the starter switch placed on “Run” position
because the battery is discharging.
2.7.4 Operation under Cold Weather Conditions
When it is difficult to start engine in cold weather, take the
following measures.
(Procedure)
① Close all the service valves and fully open the relief valve
“
1”provided at the front of the separator receiver tank.
② When engine starts after performing the startup procedure,
gradually close the relief valve, watching the rise of engine
revolutions. Then after closing the valve fully, perform
warming-up operation in this state.
Operation under Cold Weather Conditions below 23°F (-5°C)
Use SAE10W-30 (CD class) for the engine oil.
Use LLC (antifreeze). Use correct amount to provide freeze protection, according to the ambient
temperature.
Battery should always be kept fully charged.
