Engine
The PC1250LC-8, which is
equipped with the Komatsu
SAA6D170E-5 engine, is USA
EPA Tier 3 and EU stage 3A
emissions certified. The
SAA6D170E-5 engine adopts
the world’s first cooled EGR
system with electronically
controlled bypass-assist type
venturi. NOx emissions are
reduced by 40%, while
maintaining high power and
low fuel consumption.

Note: Capacities are measured at the bare stick tip.
Capacities marked with an asterisk (*) are limited by hydraulic capacities rather than stabilities.
1. Lifting capacities shown do not exceed 75% of minimum tipping loads or 87%
of hydraulic capacities. Data supplied by AEM.
2. Lifting capacities shown should not be exceeded. Weight of all lifting
accessories must be considered part of the load.
3. Lifting capacities assume the machine is standing level on a firm, uniform
supporting surface. The user must make allowances for unfavorable job
conditions such as soft or uneven ground or sudden stopping of loads.
6
4. The least stable position is over the side.

Note: Capacities are measured at the bare stick tip.
Capacities marked with an asterisk (*) are limited by hydraulic capacities rather than stabilities.
1. Lifting capacities shown do not exceed 75% of minimum tipping loads or 87%
of hydraulic capacities. Data supplied by AEM.
2. Lifting capacities shown should not be exceeded. Weight of all lifting
accessories must be considered part of the load.
3. Lifting capacities assume the machine is standing level on a firm, uniform
supporting surface. The user must make allowances for unfavorable job
conditions such as soft or uneven ground or sudden stopping of loads.
4. The least stable position is over the side.
5. The operator should be fully acquainted with the Operation Manual before
operating the machine.
6. Capacities apply only to the machine equipped as stated here.
7. Capacities are based on PCSA gross rated loads.
