Chapter 5 – Gauges and Displays
If the aerial platform chassis is out of level more than the
machine specified slope sensor alarm setting when the
main boom is raised or extended, an alarm will sound
and the tilt warning light on the lower and upper control
panels will illuminate.
If the platform is at capacity or if platform capacity is
exceeded, the platform overload light on the lower and
upper control panels will illuminate.
Fuel Gauge
The fuel gauge is located on top of the fuel tank. Access
the gauge by opening the door on the top, left rear of the
chassis (refer to Figure 5.4). Read the fuel level at the
line in the clear plastic window. The gauge indicates the
fuel tank level in fractions of a full tank.

Figure 5.4 – Fuel Tank
Note
Do not run a diesel fuel tank empty. Air in the fuel line
makes the engine hard to start.
LPG tanks have a fuel gauge that has two scales. One
scale measures the fuel level when the tank is mounted
vertical and the other is used when the tank is mounted
horizontal (refer to Figure 5.5).
Horizontal Scale
Figure 5.5 – LPG Fuel Tank
18
The LPG tank is mounted horizontally on the left side of
the chassis. Read the horizontal scale to determine the
fuel level.
Engine Oil
The engine oil level is measured with a dipstick. The dip-
stick is the only way to accurately determine the engine
oil level. The engine oil level should always be between
the add and full marks on the dipstick.
Hydraulic Fluid Filter Gauge
The fluid filter gauge (refer to Figure 5.6) is located on
the control valve behind the door on the right side of the
turntable.
Figure 5.6 – Hydraulic Fluid Filter Gauge
• During high pump flow situations, the gauge indicates
the condition of the filter.
• When the needle on the gauge is in the red zone, its
time to change the filter.
Hydraulic Fluid Level Sight Gauge
A sight gauge on the end of the reservoir displays the
level of the hydraulic fluid (refer to Figure 5.7).
Fluid Sight Gauge
Figure 5.7 – Hydraulic Fluid Gauge
Remove the engine cover and check the fluid level with the
aerial platform in the stowed position, booms completely
down and retracted. Otherwise, the cylinders act as large
reservoirs for hydraulic fluid making the level appear too
low. The fluid should be visible in the sight gauge.
