PREPARATION FOR USE
2-16.
Perform the preventive maintenance checks and services (B - Before Operation
Column) listed in Table 2-1 before doing the following procedures. These checks and
services will determine that the semitrailer is ready for operation.
Positioning the Chock
Blocks.
a.
(1) Remove chock blocks from stowage brackets.
(2) Place chock blocks behind tires on level ground or uphill slope. On
downhill slope, place chock blocks in front of tires.
b. Coupling Semitrailer To Towing Vehicle.
WARNING
Do not tow M871 or M871A1 with the M52, M52A1, or M52A2
truck tractor. The M52 five ton truck tractor's
inherent design capabilities are not compatible with
q
the semitrailer and would result in a serious
compromise to the safety of personnel and equipment.
Be sure all personnel stand clear of the towing vehicle
q
and semitrailer during coupling operations.
NOTE
Can be towed by the M915 for improved highway use only
or the M818, M931 and M932 for either highway or off-
q
road.
(1) Align towing vehicle with semitrailer.
(2) Slowly back towing vehicle into position. Be sure kingpin (1, fig. 2-14)
is in line with fifth wheel coupler jaws (2).
(3) Stop the towing vehicle just before the kingpin plate of the semitrailer
starts to ride up the approach ramps (3) of the towing vehicle.
