Performance Evaluation

Starting Reliability

Starting characteristics were evaluated across multiple temperature ranges (32°F to 95°F) and after various storage periods. Key findings include:

– Cold start (below 50°F): Typically requires 3-5 pulls with proper choke procedure
– Warm start: Consistently achieves ignition within 1-2 pulls
– After storage (30+ days with stabilized fuel): Requires 4-6 pulls on average
– Starting reliability after 100 cycles: No significant degradation observed

The CS-310’s i-30 starting system reduces pull force by approximately 30% compared to conventional recoil systems, making it accessible to users with limited upper body strength or those with previous injuries.

Cutting Performance

Cutting tests were conducted across multiple wood species and diameters to establish performance baselines:

The CS-310 maintains consistent cutting speeds in softwoods up to 12″ in diameter. Performance begins to degrade in hardwoods beyond 8″ in diameter, where larger displacement saws would be more appropriate. The saw demonstrates excellent acceleration characteristics, reaching maximum chain speed within 1.2 seconds from idle.

Chain speed retention under load is adequate for the intended use case, with only a 15% reduction in RPM when encountering knots or denser wood sections. Recovery time when the load is released averages 0.8 seconds to return to maximum chain speed.

Fuel Efficiency and Runtime

Operational runtime was measured under various cutting conditions:

– Light intermittent cutting: Approximately 45-50 minutes per tank
– Continuous moderate cutting: 30-35 minutes per tank
– Heavy-duty continuous cutting: 20-25 minutes per tank

Fuel consumption rates average 0.24 oz/min during active cutting and 0.07 oz/min at idle. The efficient engine design provides approximately 22% longer runtime than comparable competitors in the same displacement class.

Bar oil consumption maintains proper lubrication throughout the full fuel tank cycle, with the 5.6 oz capacity typically depleting in proportion to fuel consumption under normal cutting conditions.
