INSTRUMENT PANEL
Refer to the instrument panel drawing when becoming familiar with the start up procedure or any
general operating requirements of the engine.
The
"Blower"
switch (if equipped with engine) will remain in the
"ON"
position until it is turned off.
The
"Glow Plug" or pre-heat switch requires continuous pressure for whatever time it is necessary to
activate the glow plug.
The
"Oil Pressure" light will come
on
when starting the engine but should go out after the engine
starts. A low oil level in the engine crankcase or a serious oil leakage should be suspected if the light
comes
on
at any other time during engine operation.
Old style key switch is a four position selector type. Far left,
"ACCESSORY"-"OFF"-"ON"-
"START" at the far right moving clockwise. The key will spring return to the
"ON"
position when
released after start
up.
New style key switch is ON-OFF only; glow and start switches are push button type. Both must
be
engaged to start engine.
