a. Moving Tractor With Trailer Forward.
CAUTION
Do not exceed the 22% (12.4) grade limitations while operating M1088
Tractor. Failure to comply may result in damage to equipment.
NOTE
Additional information on tractor operations may be obtained from STP
55-88M12-SM.
(1) Tire Pressure. Tire pressure for the M1088 Tractor is determined by trailer payload,
vehicle speed, and the type of terrain to be crossed. Refer to Table 2-16. M1088
Speed and Tire Pressure on Highways, Table 2-17. M1088 Speed and Tire
Pressure on Gravel/Dirt, Table 2-18. M1088 Speed and Tire Pressure for Cross
Country, or Table 2-19. M1088 Speed and Tire Pressure in Sand/Mud/Snow for
correct tire pressure.
(2) Towing. When towing trailer, overall length of M1088 Tractor must be kept in mind
when passing other vehicles. During trailer towing operations, acceleration rate is
reduced and stopping distance increased.
(3) Turning. When turning corners, trailer wheels will track inside the turning radius of
M1088 Tractor. To make right or left turn at intersection, drive approximately halfway
into intersection and then turn sharply in desired direction. This will prevent trailer
from running over curb or from going in lane of oncoming traffic.
