Step 1:
Shut off drilling fluid pump.
Step 2:
Set
Throttle
at IDLE.
Step 3:
Ensure
Rotation
and
Thrust/Pullback Handles
are in NEUTRAL.
Step 4:
Start engine. Shut off engine if oil light does not go out within 15 seconds.
Never run starter motor for more than 30 seconds at a time. Allow starter motor to cool 2 minutes
between attempts.
Step 5:
Adjust
Throttle
to get an even idle speed and allow engine to warm up for 3–5 minutes.
NOTICE:
Once engine reaches operating temperature, do not idle engine for more than 5 minutes. Low
combustion chamber temperatures can cause crankcase oil dilution due to fuel not burning completely and
permits formation of gummy deposits on valves, pistons, and piston rings.
On Tier 4 Interim/Stage IIIB engines, low idle causes particulate matter to build up and will increase cycles
between regeneration.
WARNING:
Read Operator’s Manual and safety signs before operating machine.
