(1) Position the PU 794/G on as level sur- face as possible, not to exceed 15° (26 percent) slope. Prior to separating the PU-794/G from the prime mover open the ac- cessory box and remove the ground rod sections, slide hammer rod, and the ground wire assembly. The ac- cessory box cannot be accessed when the curbside handbrake is en- gaged. Failure to do so may result in serious injury or equipment dam- age. To gain entry to the accessory box the curbside handbrake must be disengaged. Be sure the wheels are blocked and leg supports down before disengaging the handbrake. When finished using the accessory box be sure curbside handbrake is engaged. Failure to observe this warning may result in serious per- sonal injury or damage to equip- ment. Wheels must be blocked, brakes set and leg supports down in support position before operating the equip- ment. Failure to do so may result in serious injury. (2) Set the hand brakes and block the wheels securely to prevent movement. (3) Pull landing leg supports down and adjust length for firm contact with the ground. b. External Fuel Line Connections. When the PU 794/G is to be operated for long intervals, fre- quent refilling of the fuel tank can be eliminated by obtaining fuel from an external source (such as a 55 gallon diesel fuel drum). Refer to TM 5-6115- 464-12. 1-9
