a. Inspection
(1) Make a complete visual inspection of
the exterior of the PU 794/G for evidence of dam-
age.
(2) Open the control panel access doors
and inspect the control panel for damage.
(3) Open the generator compartment

explains what was done to the equipment prior to
packaging and a brief description of what has to
be done to place the unit into operation. Perform
services as required by the depreservation guide.
(2) Remove the batteries from the battery

1-14. Installation.
a. PU 794/G.
(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.
