Cab and Covers
4.2 OPERATOR’S CAB
4.2.1 Operator’s Cab Description
The welded metal cab features a modular design, allowing
for a relatively quick, simple exchange of the entire cab
and/or component parts. The cab is bolted directly to the
frame.
The operator’s cab is a protective structure. The cab itself
contains rollover protective and falling object protective
structures (ROPS/FOPS) for the operator.
DO NOT weld, grind, drill, repair or modify the cab in any
way. Any modification or damage to cab structural
components requires cab replacement. The lives of the
operator and others are potentially at stake.
To help ensure optimum safety, protection and
performance, replace the cab if it is damaged. Refer to
the appropriate parts manual for ordering information.
The cab contains the seat, operating controls, numerous
panels, steering and brake components, and more.
Covers and mirrors on the machine exist for safety,
protection and appearance. They are relatively simple to
remove and replace.
4.2.2 Serial Number Decal
The cab serial number decal is located inside the cab,
under the seat. Information specified on the serial
number plate includes the cab model number, the cab
serial number and other data. Write this information down
in a convenient location to use in cab correspondence.
