service and this misuse would be very dangerous to the operator.
HWH Leveling Control Panel
The HWH Computerized Leveling system (Figure 9-5) requires minimal effort from the motor-home user.
For leveling of the motor home, perform the following steps:
Manual Leveling (Standard):
1. Turn the ignition switch to the “acc” or “on” position.
The engine must be “off” to level the coach. The
transmission shift must be in position for parking. The
park brake must be set either manually or automatically.
If the “not in park/brake” light is “on,” check or
recheck the shift and brake position.
2. Press the “hyd” button. The “hydraulic operation”
indicator light will turn “on” with a steady glow.
3. On the right-hand portion of the HWH Leveling Control touch panel, note the outline of the motor
home and the various “raise” (i.e., “up” arrow and “lower” (i.e., “down” arrow) touch buttons.
4. Press the respective “raise” (“up” arrow) button to raise the respective side or end of the motor home.
A yellow light to the front, side, or rear of the motor-home outline indicates that that side or end is low.
The “lower” (“down” arrow) buttons will lower the motor home.
Automatic Leveling
1. Turn the ignition switch to the “acc” or “on” position. The engine must be “off” to level the coach.
The transmission shift must be in position for parking. The park brake must be set either manually or
automatically. If the “not in park/brake” light is “on,” check or recheck the shift and brake position.
2. Press the “hyd” button once—the motor home will automatically level itself.
NOTE: The hydraulic jacks will always work in pairs: Front end, right side, left side, or rear end. During
transit of the motor home, the “Store” position on the HWH Leveling Console must be engaged.
Electric Steps
The Allegro Bus is equipped with electric, two-step, doorsteps (Figure 9-6). The rocker switch to operate these
steps is located in the passenger console box. When the power switch for the steps is in the “on” position,
simply open the door and the steps will automatically extend. Detailed operation for the electrical, three-step,
doorsteps is as follows:
1. Turn the step power switch “on.”
