Air Filter
Start the engine from the ground control box.
The Filter Minder gauge (1) has a yellow indicator
in it (2). As the air filter clogs the yellow indicator
raises toward the red area (3) of the sight glass.
If the indicator is in the red, after the engine has
been running for 30 seconds in Ground
Operation FAST IDLE, the air filter needs to be
replaced. (For further explanation of the Filter
Minder gauge, see “Gauges” chapter 4).
NOTE
Leave the engine running for the next step.

Charging System
With the engine running at Ground Operation
IDLE, the needle in the ammeter gauge should
not be to the left of “0” (left of “0” is discharging).

DANGER
When you check turntable Swing at CCW (1)
the turntable will move directly toward you. Be
sure you have room to step backward.
Check each of the seven platform moving
switches (2) using Ground Operation (3) to see
that they cause the ATB 42/50 to move the way it
should.
Check both positions of each switch.
For correct operating procedures see the
“Operation” chapter 8.
Pay particular attention to the Emergency Stop
switch (4) to see that it turns the ATB 42/50
engine off when struck.
Listen for the start up alarm when the Master Key
Switch (5) is first turned ON.
NOTE
Leave the engine running for the next step.
