Curves based on machine with full fuel tank, oper- ator, ROPS cab, 35/65R33 ** (L-4) tires. Extra coun- terweight as supplied with Millyard Arrangement and 431-6176 double top clamp log fork.Total oper- ating weight 63 600 kg (139,920 lb).

Curves based on machine with full fuel tank, oper- ator, ROPS cab, 45/65R39 tires. Extra counterweight as supplied by Millyard Arrangement. 315-0458 millyard forks. Total operating weight 89 963 kg (197,919 lb).

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.
