TM 5-2420-230-10
Exercise extreme caution when towing over uneven terrain to ensure that the structure of towing
vehicle and the IHMEE do not collide. Failure to comply may result in damage to the IHMEE and the
towing vehicle.
During all towing operations, ensure that the tow bar will not foul on the IHMEE or its backhoe or FEL bucket attachments
when towing over uneven terrain (such as crossing a ditch or ridge).
If the IHMEE engine is not operational, it will not be possible to release the parking brake. To overcome this, it is possible to
attach a slave air supply to the IHMEE. This will allow the parking brake to be released and will also allow normal operation
of the footbrake.
Caging the spring brake chambers is for emergency towing of the vehicle only, and will manually
release the vehicle's brakes. Ensure that vehicle is secured by the towing vehicle or wheel chocks
before caging the brake. Failure to comply may allow the IHMEE to move, resulting in serious injury
or death to personnel and/or equipment damage.
If a slave air supply is not available, it is possible to manually release the vehicle's brakes (refer to Para 3-29). Exercise
extreme caution after caging the brakes, because no braking actions will be available on the IHMEE.
If the engine is not running while the vehicle is being towed, the power steering does not operate, and the steering requires
more effort to operate.
The IHMEE's front towing points are limited to a maximum force of 12,000 lbf (53,400 N) before
permanent damage will occur. Exceeding this force will cause damage to the vehicle.
Always tow the IHMEE by the rear towing points (1) whenever possible. The front towing points (2) must only be used when
the towing vehicle cannot attach to the rear towing points for some reason.
