Safety Practices
19 Model 644E Origin 3/04
10. Tire Pressure
MAINTAIN proper tire pressures at all times. An underpressurized tire(s)
adversely affects vehicle stability. If proper tire pressures are not maintained,
this vehicle can tip over.
To ensure proper vehicle stability, check all four tire pressures before operating
the vehicle.
11. Do Not Jump
If a vehicle ever becomes unstable and starts to tip
over:
ï BRACE YOURSELF and STAY WITH THE
VEHICLE,
ï KEEP YOUR SEAT BELT FASTENED,
ï HOLD ON FIRMLY and
ï LEAN AWAY FROM THE POINT OF
IMPACT.
Indecision and trying to escape from a tipping
vehicle can result in death or serious personal
injury.
12. Slopes
DO NOT park the vehicle on an incline and leave it unattended.
ï Driving across a slope is dangerous, as unexpected changes in the
slope can cause tipover. Ascend or descend slopes slowly and with
caution.
ï Ascend or descend slopes with the heavy end of the vehicle pointing up
the slope.
NOTE: The rear of the vehicle is normally considered the heavy end unless the car-
riage is fully loaded. In this case the front of the vehicle is now the heavy end.
ï Unloaded vehicles should be operated on all slopes with the carriage
pointing down the slope.
ï On all slopes, the load must be tilted back and raised only as far as
necessary to clear the ground.
ï When operating on a downhill slope, reduce travel speed and downshift
to a low gear to permit compression braking by the engine and aid the
application of the service brakes.
