TMS9000-2 SERVICE MANUAL
The air intake filter is located on the right side of the engine
on the fender. The muffler is located on the left side behind
the cab.
To aid in starting the engine in cold weather, an automatic
cold weather starting aid injection system is provided. When
engine temperature is below 13°C (55°F) the automatic cold
start solenoid is activated when the engine is started,
providing an injection of starting fluid to the engine. The
system consists of an engine temperature switch, solenoid
valve, starting aid container, and the necessary connecting
tubing. The solenoid and container are mounted inside the
hood on the left side. An immersion type engine block heater
is also provided.
