for operators convenience.

The operator can easily control the
temperature and air flow. The
defroster on the front windshield and
rear window makes it convenient for
winter working usage.

Joystick Controls

Boom an bucket are operated by a
pilot-pressure controlled joystick.

(Option)

A single lever on the left side of the
steering column gives the operator
fast and easy control of speed and
direction. Push the lever forward to
drive forward, pull it back for
reverse. Travelling is automatically
changed from 1st stage to given
stage according to travel speed and
traction effort. The operator can
select two kinds of automatic
modes (1st<->4th, 2nd<->4th). This
exclusive feature contributes to a
step-up in productivity and
reduction of operator’s fatigue.

Engine control Unit (ECU), Trans­mission control Unit (TCU) and
Machine control Unit (MCU) realize
the optimal performance through the
mutual CAN communications.

The Air Conditioning and Heating System

Up-to-Date-technology CAN System

Ride control is available for smooth travelling. It significantly reduces
machine bouncing and absorbs the shocks in the machine, enhancing
productivity. This system reduces the fatigue of the driver as well as the
stress on the structures and components.

Ride control system

Control Center

The fully new, deluxe operating space was engineered by using 3-D modelling to
optimize drivers comfort. The wide, tinted and laminated front windshield has no
frame cutting through to ensure excellent visibility.

The CUMMINS QSB6.7 electronic control
engine combines full-authority electronic
controls with reliable performance. The
combination of improved airflow and evenly
dispersed fuel results in increased power,
improved transient response and reduced
fuel consumption. Through the use of
advanced electronics, the QSB6.7 the engine
meets the emission standards EPA TierIII/EU
StageIII.

A Well Rounded System

Maximize your business productivity with HL760-7A.
With our vast experience in the production of construction equipment,
Hyundai is able to meet our customers demands.

Left and right access door Bucket cylinder guard

This guard helps to prevent possible
damage while loading material.

Wear plate

This close up shows the protective
plating found underneath the rear of
the bucket and is used to prevent
excess wear when digging into
material.

High-rigidity frames

Front and rear frames are designed
to work in the toughest conditions
and provide high rigidity for the
power train and loader equipment.
The sturdy frames, together with the
reinforced front/rear frame linkage,
resist loading stress and shocks
while in operation.

Battery master switch

A master switch disconnects the battery power
to protect the electrical system from excessive
electrical drainage.

Sealed loader linkage

Fully protected fitting including dust seals and o­rings on the bucket linkage will extend lubrication
intervals remarkably.

Frame lock

The machine can be locked by a locking bar to
prevent movement during transportation.

Multi Function Transmission

The newly developed transmission control represents the beating heart of transmission. The hydraulically operated
gear shifting with proportional valves allows precise clutch operation. For each gear change, the control unit
performs a monitoring function to ensure that the specified shift curve is adhered to, and readjusts the shift
pressure applied to the clutches accordingly. This result in smooth gearshifts under load without traction
interrupts. It also prevents standstills, sudden load changes or torque peaks during operation such as steep hill
driving with full load. In addition, there is the option for the driver to make manual gearshifts.

Accessible and Serviceable

New Generation, Innovative Solution in Earth Moving, the

HL760-7A

Accessible grease fittings

Grease fittings are highlighted and
centralized on the machine for fast
access when doing your service
checks.

Simple air filter
replacements

The air cleaner is easily replaceable
by turning the wing nut on the outer
shell counter-clockwise.

Open pin access

You can quicker remove or tighten
your front attachment pin
(chromated) with this open
connector system.

Remote type drain port

It is now easier to change your
engine oil, coolant and hydraulic oil
with the remote drain port located
near the rear axle of the machine.

An ideal arrangement of components ensures easy access and convenience for maintenance.
A highly accessible engine compartment assures fast and efficient maintenance.

Hydraulic tank

The hydraulic tank is located behind the cab to facilitate accessibility of
hydraulic hoses and piping.

Oil sight gauge

A sight gauge is installed on the side
of the hydraulic tank for convenient
ground level check out.

Transmission oil port

The transmission oil change port is
openly accessible. It comes with an
anti-vandalism lock for machine
protection.

Centralised electric controllers &
Fuse Box

The electric controllers for this loader are
centralized together with the fuse box to improve
serviceability and facilitate inspections.

Cabin Air Fresh Filter

The internal pressure is maintained slightly higher
than that of outside to exclude dust from and
reduce noise level in the cabin.

Coolant Sight Gauge

A sight gauge is installed on top of the radiator
tank for convenient checks of the coolant level.

Easy Access to All Engine
Components

Up-to-date hydraulic remote
cooling fan

Here you find engine oil check and
main and pre-filters. The large
access engine-side-panels permit
easy and safe inspections. The fuel
and oil filters can be spun on and
off for quick replacements.

Minimum fuel consumption and
low noise is realized by using a
hydraulic cooling fan sensing
coolant temperature, intake air
temperature, transmission oil
temperature and hydraulic oil
temperature. Reversible cooling
fan is installed.
