WARNING
• Sound the horn before starting the engine and
after confirming that the machine’s surroundings
are clear of personnel and obstructions.
• 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 that could result in death or serious
injury.

monoxide is an invisible and odorless gas.
Carbon monoxide is toxic and could result in
death or serious injury. Provide adequate
ventilation when starting the engine in a confined
space.

Drain the water and sediment from the primary fuel
filter/water separator once a week. See “Check the
Primary Fuel Filter/Water Separator” on page 5-17.

“Battery Disconnect Switch” on page 3-15.

The machine should not start when the hydraulic
lockout control lever is in the unlocked (open)
position. If it does, contact a SANY dealer. Failure
to correct this could result in death or serious
injury.
