Note (1)
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 2.4 kg (5.29 Ibs) of refrigerant, which has a CO2 equivalent of 3.43 metric tonnes (3.78 tons). -
Note (1)
Productive capabilities of the 773 truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production. -
Note (2)
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection. -
Note (1)
For cab offered by Caterpillar, the operator sound exposure Leq (Equivalent Sound Pressure Level) is 80 dB(A) when measured according to work cycle procedures specified in SAE J1166:2008. This occurs when the cab is properly installed and maintained. The test was conducted with doors and windows closed. -
Note (2)
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment. -
