The 830E deck components are removable in sec-
tions as shown in Figure 2-1. The following removal
and installation instructions detail the steps to be
taken before the decks and hood can be removed.
Additional steps may be required before the deck or
another major structure is removed, depending on
optional equipment installed on the truck at the fac-
tory or after delivery.
Prior to removal or repair procedures, it may be nec-
essary to remove the body to provide clearance for
lifting equipment to be used. If body removal is not
required, the body should be raised and the safety
cables installed at the rear of the truck.
Read and observe the following instructions
before attempting any repairs!
• Do not attempt to work in deck area until body
safety cables have been installed.
• Do not step on or use any power cable as a
handhold when the engine is running.
• Do not open any electrical cabinet covers or
touch the retarding grid elements until all
shutdown procedures have been followed.
• All removal, repairs and installation of
propulsion system electrical components,
cables etc. must be performed by an
electrical maintenance technician properly
trained to service the system.
• In
the
event
of
malfunction, a qualified technician should
inspect the truck and verify the propulsion
system does not have dangerous voltage
levels present before repairs are started.
After the truck is parked in position for the repairs,
the truck must be shut down properly to ensure the
safety of those working in the areas of the deck, elec-
trical cabinet and retarding grids. The following pro-
cedures will ensure the electrical system is properly
discharged before repairs are started.

cab.
•
All hoses and mating fittings should be capped as
they are removed to prevent possible system
contamination.
•
It is important to tag and visually verify all cables,
harnesses, hoses etc. have been removed
before the structure is lifted off the truck.
