Structural Components; Deck Components; Preparation - Komatsu 930E-2 Shop Manual

The 930E deck components are removable in sections
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 other major
structure is removed, depending on optional equip-
ment installed on the truck at the factory or after deliv-
ery.
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 shut-
down procedures have been followed.
• • • •
All removal, repairs and installation of propul-
sion system electrical components, cables etc.
must be performed by an electrical mainte-
nance technician properly trained to service
the system.
• • • •
In the event of a propulsion system malfunc-
tion, a qualified technician should inspect the
truck and verify the propulsion system does
not have dangerous voltage levels present be-
fore 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, electrical
cabinet and retarding grids. The following procedures
will ensure the electrical system is properly discharged
before repairs are started.
