The maximum speed of each M1977 CBT and M1075 PLS based launch vehicle,
with or without trailers, should be limited to 40 mph when operated on improved
roads. If traversal of cross-country terrain is necessary to access an operation site
then the M1977 CBT and M1075 PLS based launch vehicle, with or without trailers,
should be limited to a maximum speed of 15 mph. The M1076 trailers should be
limited to a maximum speed of 10 mph on Belgian block, cobblestone, or surfaces
with heavy washboard, ruts, or potholes.
on Sloping Ground
Caution must be exercised when operating the DSB vehicles and trailers on slopes.
The DSB vehicles should be limited to side slopes not to exceed 20%. The
possibility of rollover exists on any slope (including level), but will be minimized
provided that operating speeds are kept to a minimum, no sudden steering inputs
are made, and depressions are avoided when traversing undulating terrain.
Operators must be made aware of these operating characteristics and limitations.
Drive on mud, snow, ice and slippery surfaces as follows:
a. Move the CTIS switch to ON position and set the CTIS rotary selection switch
b. Press the throttle control (Figure 12. 14. (10)) slowly when changing speed.
Keep the throttle control (Figure 12. 14. (10)) steady after the launch vehicle
reaches the desired speed.
d. Turn the launch vehicle slowly when on slippery surfaces.
e. Steer the launch vehicle away from ruts and large snow banks.
