FUEL EFFICIENT
•	Piston pumps are load sensing so they provide efficient use of hydraulic power and response with the lowest horsepower demand.
•	Controlled acceleration allows the 70Z7 to achieve excellent acceleration without unnecessary fuel consumption. This is achieved through sophisticated logic in the controller that allows for precise fuel delivery to match acceleration objectives.
•	Transmission shift points are flexible to match working conditions to allow for the proper speed/rimpull balance to meet the job conditions.
•	Fuel efficient Cummins engines are designed to minimize fuel consumption.

OPEN CENTER LOAD-SENSING HYDRAULICS
•	Responsive - operator senses load resistance
•	Industry exclusive
•	Reliable

EFFICIENT OPERATION
•	Power modes for high power demands or high fuel efficiency
•	High efficiency bucket design loads faster, retains more material, increases productivity

SERVICING
•	Extended Lube Intervals from patented HN bushings — up to 500 hours
•	Extended hydraulic oil change interval — 4000 hours when using KCM SuperEX46 fluid
•	Extended engine oil change interval — 500 hours when using required low ash, CJ-4 oil
•	Accessible filters, ground level fueling, tank sight gauges, grouped grease fittings


RELIABLE CUMMINS POWER
•	Cummins QSB6.7 diesel with a big 168 horsepower provides excellent power
•	Tier 4 Final Certified, clean
•	Reliable, long life engine
•	Proven performance and efficiency
•	Extensive support network throughout North America provides outstanding service


INTELLITECH SYSTEM
•	IntelliDig system balances rimpull force with the breakout force to provide optimum digging performance automatically
•	Variable, reversible fan is aerodynamically designed for efficient airflow, with variable speed to reduce energy loss when high fan speed is not required and is automatically reversible to keep the cores cleaner in dusty conditions for better efficiency.


COMFORT MEANS PRODUCTIVITY
•	Hydraulic controls are fingertip, pilot assisted levers. Either single or dual lever controls are available to fit the operator preference.
•	Sound levels are low to reduce operator fatigue and allow the operator to monitor external noises for increased comfort and safety.
•	The air suspension seat provides outstanding comfort and adjustability which keeps the operator comfortable over the entire work shift.
•	The steering wheel has a tilting/telescoping steering column that adjusts to fit operator preference.

	•	Grouped lube points
	•	Ground-level fluid check points
	•	Ground-level fueling
	•	Fuse/relay panel in cab
	•	Autolube, optional

	EXTENDED SERVICE INTERVALS
	•	KCM Super EX46 is a specially formulated hydraulic fluid with no zinc additive. Zinc causes a sludge buildup in oil that shortens the effective life of the oil. By using KCM Super EX46 HN Hydraulic Fluid the sludge buildup is reduced which allows for extended life, which lowers operating costs.
	•	Using CJ4 engine oil, which is a low ash oil, allows the change intervals to be extended. By doubling the oil change interval from 250 hours to 500 hours, the time and cost of engine oil changes are cut in half.
	•	The patented HN™ bushings are impregnated with high viscosity oil to provide added lubrication. This allows the lubrication interval to be extended on bucket linkage pins. The lubricant is replenished every time the pin is greased.

	TELEMATICS
	•	Global e-Service is the proprietary telematics system for KCM loaders. This system monitors all machine systems and collects operating data and alerts, which it transmits to equipment managers, dealers and factory support staff at KCM. This system allows for more efficient management of fleets, control of maintenance schedules and notification of alerts that can reduce downtime and operating costs.
