- Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
- Lock-up Torque Converter – Transfers more power to the ground and optimizes fuel efficiency in all applications.
Machine configuration, operator technique, and job site layout can impact fuel consumption.
- Machine Configuration – Select the correct work tool and tire type based on machine application. Ensure proper inflation pressures. Utilize the Economy Mode setting for maximum efficiency.
- Job Site Layout – Spot loading targets in the right position. Avoid traveling more than 1.5 tire revolutions during truck loading cycles. Reduce transport distance for load and carry cycles by optimizing job site layout.
- Loading Bucket – Load in first gear. Raise and tilt bucket quickly and do not use a “pumping” motion. Avoid lift lever detent and use impeller clutch.
- Loading Truck or Hopper – Do not raise the work tool any higher than necessary. Keep engine rpm low and unload in controlled manner.
