Control of loader boom, auxiliary hydraulics and other functions
Most of the functions of the loader are controlled at the control panel on the right side of the operator: Boom and bucket
movements, auxiliary hydraulics (attachments), engine revs etc. , depending on loader model. Following pictures show the
different functions:
Attachment control switch pack
• Optional extra with which electric
functions of the attachment are
controlled
• Consists of 3 pcs control switches, wiring
and a 7-pole socket which mounts on
the auxiliary hydraulics multi connector. The corresponding
socket of the attachment electric wire
is mounted on the attachment multi
connector. This way both the electric
wire and the hydraulic hoses of the
attachments are connected at the same
time with the multi connector.
• Read the operator’s manual of the
attachment to see how the switches
are used with each attachment.
Control lever of boom and bucket
• Pull backward to lift the boom
• Push forward to lower the boom
• Push left to raise the tip of the bucket (filling)
• Push right to lower the tip of the bucket (emptying)
Hand throttle lever
• Push forward to increase engine revs
• Pull backward to reduce engine revs
Control lever of auxiliary hydraulics
(hydraulically operated attachments)
• Push right carefully to test the operating direction of
the attachment
• For continuous operation of rotating atatchments,
push right & forward to locking position
• Pull left to operate the attachment in reversed
direction
• When using the electric joystick, this lever will
also move. Either way can be used to control the
attachment as needed.
Control lever of telescopic boom
• Push right to extend the boom
• Pull left to retract the boom
Seat heater
The suspension seat is equipped
with an electric seat heater. Seat
heater switch and indicator
are located on the dashboard.
Boom floating
The floating system releases the lift cylinder, so that the
boom floats upwards from the position where it is when
boom floating is switched on, allowing the attachment to
follow the contours of the terrain.
1. Lower the boom down
2. Switch on the floating with
rocker switch no.
3. Boom floating indicator
on the dashboard lights up
When boom floating is being used, it is
possible that air gets in the hydraulic system.
This can lead to inaccurate boom movements
and the boom can give in. Therefore the
boom and attachment coupling plate should
always be moved to extreme end positions
after switching off boom floating. Use boom
floating only when necessary.
Joystick
The loader is equipped, as an
option with the 6 function joystick,
where the operation of auxiliary
hydraulics and telescopic boom is
electric.
1. Auxiliary hydraulics
• push the buttons to engage
and disengage auxiliary
hydraulics.
Engine block heater
The loader can be equipped, as an option, with an engine
block heater. Engine block heater outlet (220V-240V) is on
the right side in the rear of the machine.
Controls in the footwell
1. Drive pedal, left: drive backward
2. Drive pedal, right: drive forward
3. Parking/emergency brake handle
• locking: pull the handle and turn down into
locking position
• releasing: turn up and let the handle go down
Parking brake locks mechanically - springloaded pins go into the holes of the parking brake drum on the front wheels.
Make sure that the brake locks properly
by driving a bit forward or backward.
Suspension seat
The suspension seat is equipped with seat belt, arm rests
and heater and has the following adjustments:
1. Suspension adjustment
• by turning the knob counterclockwise suspension
gets harder, by turning it clockwise the suspension
gets softer
2. Angle of the back rest
• the angle of the back rest can be adjusted by
turning the knob
3. Seat position
• the distance of the seat from the steering wheel can
be adjusted with the lever which is located under
the front edge of the seat
4. Arm rest angle adjustment
• The angle of the arm rest can be adjusted by turning
the roller under the arm rest
Seat belt and seat adjustments
Always use seat belt while driving. Make sure that the
seat is properly adjusted to keep vibrations transmitted by
the seat at minimum. Long term exposure to vibrations
may cause health effects. Also, as far as possible, keep the
operating terrain in good condition to minimize vibrations
Telescopic boom
Telescopic boom is operated with
the control lever no. 8 on the
control panel or with
the rocker switch on the joystick
Length of the
telescope is 600 mm and additional
lifting height is 485 mm.
Battery disconnect switch
The loader is equipped with a
battery disconnect switch. The
switch is located in the rear of the
machine, on the right side. Battery disconnect
switch cuts the current between
battery and the rest of the electric
system. Always switch off main
current when the loader is not
used for a longer period of time
in order that the battery doesn’t
get empty, or when servicing the machine.
Trailer coupling
The loader can be equipped, as
an option, with a trailer coupling.
There are two types available: a
50 mm ball hitch and a 50 mm ball
hitch with towing pin. Both can
be mounted either directly on the
rear bumper or on the extra back
weight.
Max. allowed vertical load of the
trailer coupling is 6900 N, max.
towing load is 6000 N.
Make sure that the weight on the trailer is distributed
correctly so that the trailer cannot cause an upward lifting
force on the trailer coupling
Extra counterweights
The loader can be equipped with
extra counterweights that are
mounted on the rear bumper.
Max. amount of extra weights
(29 kg/pcs) is 3 pcs. If the machine
is fitted with an extra weight with
trailer coupling, max. amount of
extra weights is 1 pcs. The loader
can also be equipped with an
extra side weight kit (80 kg) which
mounts behind the rear wheels.
Work light kit
The loader can be equipped with
extra work lights, making it easier
to work in low light. The lights are
operated with the switch on the
control panel.
Headlight, beacon, blinker & reflector kit
This optional equipment enables
road traffic registration in certain
countries. Requirements vary in
different countries, please consult
your local AVANT distributor.
Tilt adapter
The hydraulic tilt adapter mounts
between the attachment and the
attachment coupling plate. It allows
the driver to tilt the attachment
sideways to both directions from
the driver’s seat. Tilt adapter is
intended mainly for non-hydraulic
attachments, but with the optional double acting extra
auxiliary hydraulics outlet in the front (A35504) it is possible
to mount a hydraulically operated attachment at the same time. Tilt adapter is operated with the
auxiliary hydraulics control lever.
Drive release valve
The switch no. 16, LOCK, controls
a valve, which is used to divert the
oil flow between left and right side
hydraulic motors, and this affects
the pulling force.
LOCK OFF: In this mode, the
hydraulic oil flows in series from motor to motor. The
wheels will roll more freely and the loader leaves less tire
marks on soft surfaces.
LOCK ON: In this mode the hydraulic oil flows in parallel
between the hydraulic motors in each side, similar to a
differential lock in operation. This improves the towing
capability of the loader.
Anti slip valve
The valve positively diverts oil flow
between the right and left side
hydraulic motors and improves
traction on slippery and uneven
surfaces. It is engaged by switch
LOCK ON : Anti slip valve diverts oil flow between all
four hydraulic motors - all four wheels have best possible
traction. Use sufficient engine revs and press properly on
the drive pedal.
LOCK OFF: Drive circuit released – anti slip valve diverts
the oil flow between the front left and right hydraulic
motor only, not the rear hydraulic motors.
Starting the engine
Before starting the engine do the daily checks, Adjust the seat and mirrors (if fitted) so that you have a good
working position and unrestricted field of vision from the driver’s seat. Check that all controls function correctly.
to it that the operating area is safe. Read and follow operating and safety instructions.
Stopping the engine (Safe stopping procedure)
1. Lower the boom completely down. Place attachment firmly on the ground, engage parking brake, stop the attachment
(move auxiliary hydraulics control lever to neutral position, set engine revs to idle.
2. Stop the engine by turning the ignition key to the OFF position (to the left)
3. Release auxiliary hydraulics pressure.
4. Prevent unauthorized use of the loader. Take off the ignition switch and turn the power off with the battery disconnect switch.
Stop the engine as soon as possible, if any of the following symptoms is observed. Find out the cause before restarting.
• The oil pressure warning light turns on during operation.
• A sudden and unusual noise is heard
• The colour of the exhaust fumes suddenly darkens or turns white.
1. Turn the battery disconnect switch to ON
2. Move the hand throttle lever to approximately ¼ throttle
3. Make sure that auxiliary hydraulics is switched off (lever in neutral
position). Do not press on the drive pedals.
4. Turn the ignition key to the right until the glow plug
indicator light turns on.
5. After the glow plug indicator light turns of turn the ignition
2 key further to the right until the engine starts.
Do not actuate the starter for more than 10 seconds at a time. If the engine does not start, wait for one minute before
repeating attempt. If the engine does not start after a few attempts, or runs poorly, see troubleshooting and
the engine owner’s manual.
If auxiliary hydraulics is switched on during starting and there is a hydraulically operated attachment on the
machine, the attachment can move suddenly and cause a dangerous situation. Make sure that the auxiliary
hydraulics control lever is in neutral position during starting.
The engine cannot start if auxiliary hydraulics control lever is in locking position.
Familiarise yourself with the driving of the machine on low speed and on a flat, even
and open place where unintended movements don’t cause problems or danger. When
you have learned how to drive on low speed, increase speed gradually and learn how
to drive with higher drive speeds. Make sure that there are no persons in the operating
area of the machine.
Principle of operation
AVANT is equipped with a hydrostatic drive system, a variable displacement
hydraulic pump in the drive circuit is proportianally controlled with the two drive
pedals. Driving of the machine is controlled with the drive pedals and hand throttle.
Suitable engine speed is selected with the hand throttle lever on the control panel,
and desired driving direction and speed are controlled with the drive pedals. To get
maximum pushing power push the pedals lightly – for higher travel speed push the
pedal harder.
Drive conrtol
• Driving forward: press gently on the right drive pedal until the machine starts to move
slowly.
• To drive backward: press gently on the left drive pedal.
• When you wish to stop gently release the pedal by lifting of your foot, and the machine
will slow and stop.
The hand throttle can be used to control engine speed also while driving. The basic
rule is: use lower revs for lighter work and higher revs for hard work or for high travel
speed.
The hand throttle also has an effect on the operation speed of a hydraulically driven
attachment: the more throttle the faster the attachment operates. Make sure not to
exceed max. allowed oil flow of the attachment.
When you want to have a high pulling force:
1. Use high engine revs
2. Press the drive pedal only lightly to select a relatively slow drive speed. This way the
full output of the hydraulic system and the engine can be taken out. If the engine is
overloaded while pushing, the pedal shouldn’t be pressed further, but instead use
higher engine revs and push pedal only a little.
Steering of the machine
Steering of the machine happens with the steering wheel.
The steering wheel is hydraulically powered. A practical
way of steering is to steer with your left hand on the knob
of the steering wheel. This way your right hand is free to
operate other functions.
Always remember – safety first. Test all the
functions of the loader at an open and safe
place. Make sure that there are no persons
in the operating area of the machine and
the danger zone of the attachment.
When driving, always keep the loader
boom as low as possible. Risk of tipping
over increases considerably when there
is a heavy load on the loader (a heavy
attachment or a big load in the bucket) and
the boom is up when driving.
Never use a high drive speed when turning.
In particular: when the loader boom is up
the stability of the machine is much weaker
when turning.
Remember that, when turning, the driver´s
seat extends beyond the turning radius of
the wheels. Stay inside the safety frame.
