Operating Costs
Save Time and Money by Working Smart.
Data from customer machines show Cat wheel loaders are
among the most fuel efficient machines in the industry.
Several features contribute to this excellent fuel efficiency:
• Performance Series Buckets – Deliver faster fill times and
better material retention, ultimately reducing cycle times while
improving productivity and fuel efficiency.
• Positive Flow Control Hydraulics – Provides only the hydraulic
flow required by the implement and steering systems for
improved fuel efficiency and greater rimpull.
• ACERT Engine – Advanced engine controls maximizes power
and efficiency.
• Economy Mode – Featuring On Demand Throttle, Economy
Mode optimizes power for maximum fuel savings with minimal
impact on production.
• 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.
• Advanced Productivity Electronic Control Strategy (APECS) –
All new APECS transmission controls provides greater
momentum on grades and fuel savings by carrying that
momentum through the shift points.
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.
• Idle – Set the parking brake to engage Engine Idle
Management System.

Note: Rated Payload is the material weight in the bucket that the loader is designed to carry, excluding the weight of the bucket, GET, and wear material. Rated Payloads
are published at 100%, even though Caterpillar does allow 110%. These values are given in terms of mass. There is no consideration to loose density weights of
various materials since they are so diverse.
