Idling the Engine
Idling the engine for long periods wastes fuel and causes carbon formation, oil dilution, formation of lacquer or
gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine.
Allow the engine to idle until it reaches normal operating temperatures before beginning operation.
Cold Weather Engine Starting
Start the engine with the following procedures in cold temperatures:
1. Check the fluid levels before starting the engine. Drain the water and sediment from the fuel/water separator.
See “Check and Drain the Primary Fuel Filter/Water Separator” on page
WARNING!
•
Before starting the engine or leaving the operator seat, make sure the hydraulic lockout
control lever is in the locked (closed) position. If the hydraulic system is not locked,
unintentional machine operation may occur.
•
Confirm that the surrounding area is clear of personnel and obstructions, and sound the
horn before starting the engine.
•
Always start the engine from the operator seat. Never start the engine by shorting the
starter solenoid or starter relay.
•
Never use ether starting fluid to start the engine. Ether is highly flammable and can cause
a fire or an explosion.
•
Exhaust gas contains carbon monoxide. Carbon monoxide is an invisible and odorless
gas, and is toxic. Provide adequate ventilation when starting the engine in a confined
space.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
•
Never crank the engine for more than 15 seconds.
•
If the engine fails to start after 15 seconds, stop and allow the starter motor to cool for at
least 2 minutes before attempting another start.
•
If the engine fails to start after five attempts, contact a SANY dealer.
Failure to follow this notice could damage the machine or cause it to operate improperly.
