NOTE:
Static tipping load and operating weight are based on machine configuration with standard tires,
full fuel tank, coolant, lubricants, and operator.
Specifications and ratings conform to all applicable standards recommended by the Society of
Automotive Engineers (SAE). SAE Standards J732 JUN92 and J742 FEB85 govern loader ratings.
The rated operating load for a machine with fork is: SAE J1197; 50% of full turn static tipping load,
or hydraulic/structural limit. CEN 474-3: 60% of full turn tipping load on rough terrain: 80% of full
turn tipping load on firm and level ground, or hydraulic structural limit.
