Leveling System (Hydraulic) - Tiffin Motorhomes 2014 Allegro Owner's Manual

TIFFIN MOTORHOMES
Do not exceed the maximum rating of the ladder (i.e., 200-pound load limit).
Do not attempt to walk on the roof either while it is wet or when condensation is
present from the air-conditioning system, as that surface would be quite slippery.

Leveling System (Hydraulic)

HYDRAULIC LEVELING SYSTEM
The Allegro is equipped with hydraulic-leveling jacks. These jacks work in pairs: Front, right side, left side, and rear.
Before extending these jacks, the engine must be "off," the ignition switch must be in the "ACC" position, and the
transmission must be in "park." The parking brake needs to be set and the tires blocked securely; then the leveling
jacks can be activated.
DO NOT LIFT the wheels of the motor home off the ground when leveling—if done,
the motor home can tilt forwards or backwards when supported only by the leveling
jacks. Never use the jacks to lift the motor home off the ground to change the tires
or perform any under-chassis maintenance—these jacks are not meant for this type
of 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.
