Safety instructions
Handling of heavy loads
WARNING
Handle loader with care - Risk of
tipping over.
• Follow all instructions and warning
labels to avoid tipping over of the
loader.
• Always put the load down on the
ground before you leave the driver’s
seat.
• Keep loads as low and as close to the
loader as possible.
• When loading, always keep the loader
frame as straight as possible.
• Never drag a heavy load with the
loader from high level – e.g. from
truck, shelf etc.
• Always handle heavy loads only on firm, level ground,
while you drive slowly with the machine.
- Uneven or inclined terrain significantly reduces the
safe working load, (see also page 23.)
- Use the maximum loads indicated in the diagram in
this manual as a guideline.
- All rated operating capacities are based on the
criteria of the machine is level on a firm supporting
ground. When the machine is operated in conditions
that deviate from these criteria (e.g. on soft or uneven
ground, on a slope or when subject to slide loads),
you must take these conditions into account.
- Remember that the actual load carrying capacity
varies greatly according to operating conditions and
control manner.
- Be especially careful when the load sensor indicator
is activated. See page 23 for more information about
the load sensor.
• Keep the articulated frame of the loader in straight position
when you lift heavy loads. If you turn the loader during
load handling, the stability of the loader will decrease and
it may overturn the machine.
• The use of extra rear weights or ballasted tires is
recommended. See page 34 for different options.
• Make sure to follow the recommended tire pressures.
• Pay attention that a heavy load or long distance between
the loader and the center of gravity of the load will affect
the balance and handling of the loader.
• When you estimate the lifting capacity of the loader,
remember to take the weight of the attachment into
account.
7
Safety instructions
400 Series
Whenever you handle heavy loads or heavy attachments:
CAUTION
In case the loader tips over :
Overload - Risk of overturning.
The high lift capacity of the loader makes
it possible to exceed the stability of
the loader when handling loads. Read
the instructions regarding maximum
lift capacity and load handling in this
Operator’s Manual. Following the
instructions reduces the risk of tipping
the machine over its front axle, but the
operator must be aware of the limits of
the machine and follow safe working
practises to avoid overturning of the
machine.
Avoid tipping over of the loader with careful operation and
the instructions given throughout this manual. However, it
is important to know what to do in case the machine tips
over.
WARNING
NOTICE
WARNING
WARNING
Articulated frame - Risk of
overturning. Turning articulated frame
can lead to overturning of the loader
on inclined terrain or when driving at
high speed. Never turn frame towards
the slope while operating on inclined
ground. Always drive slowly when
carrying load or when turning with the
machine.
Sudden movements can tip the
machine over - Risk of overturning.
Movements, such as stopping, turning,
or lowering the boom abruptly, can
cause loss of stability. Always drive
slowly and operate the controls of the
loader very carefully, especially when
handling heavy loads.
8
Risk of being crushed by the ROPS
structure in case the laoder tips over
- Always use the seat belt and stay
within the space protected by the
ROPS safety frame.
Always keep seatbelt on to stay on
driver’s seat and to avoid getting crushed
between ground and a loader that tips
over.
In case the loader tips over: Switch
off the engine of the loader immediately.
Running the engine and pumps of an
overturned loader will damage them
quickly and will spill hydraulic oil and
fuel. As soon as possible, lift the loader
back on its wheels to prevent spilling of
fuel and oils. The loader can in many
cases be lifted back on its wheels
by having a few persons to lift it from
the ROPS frame. Engine oil can leak
inside the engine, causing major engine
damage if the engine is attempted to
be restarted after the loader has been
overturned. Contact service before you
attempt to restart the engine.
400 Series
Operation on gradients
Safety instructions
Suffocation hazard - Ensure ventilation
Load, unload, and turn on flat level ground only. Drive slowly
on uneven terrains. Do not drive on too steep a gradient watch out for ditches, manholes and steep gradients.
Do not park the machine on a surface with a gradient.
Should this be necessary, engage the parking brake and
preferably turn the machine sideways and put down the
load. If needed, use chocks behind the wheels.
Use low speed range when driving on hills or uneven
terrain.
DANGER
Risk of tipping over - Always keep
loads close to the ground. The
stability and the load handling capacity
of the loader are significantly reduced
on inclined terrains and Maximum
lifting capacity can be achieved only on
firm, level ground. On horizontally tilted
terrain the load must be kept close to
the ground and must never be lifted
high.
DANGER
Engine exhaust contains carbon
monoxide (CO), a poison gas you
cannot see or smell. Using a loader
in enclosed space or poorly ventilated
areas will kill you in minutes.
Never operate the loader indoors or in partly enclosed
areas unless you’ve made sure there is special ventilation
system installed. Loaders with a combustion engine produce,
among other pollutants, carbon dioxide (CO2) and can also
emit carbon monoxide (CO) under some conditions that can
concentrate quickly to a dangerous level. Never leave the
engine running in garages or sheds. Operate the loader
only outdoors and far from windows, doors, and vents.
Elevated level of carbon dioxide or carbon monoxide
in breathing air can not be noticed without dedicated
measuring equipment. Signs of carbon monoxide poisoning
include nausea, headache, dizziness, drowsiness, and lack
of consciousness.
Get fresh air if anyone shows signs of carbon monoxide
poisoning and see a physician.
Diesel exhaust also contains other chemicals that are
harmful. Prolonged exposure to exhaust fumes should be
avoided. Ventilate indoor spaces well e.g. after starting a
loader. The odor or colour of diesel exhaust does not tell
if there are dangerous levels of carbon dioxide or carbon
monoxide in the breathing air.

Tipping load
Tipping load
Load diagram
Tipping load is the load at which the rear tires lose contact
with the ground (tipping forward). Tipping load is influenced
by several factors:
You can evaluate the load handling capability of the
loader with the load diagram, shown below, and the Rated
operating capacity shown on the next page and on the
label on the loader.The load handling capability depends
on the distance between the centre of gravity of the load
and the front axle of the loader.The diagram represents
the forward stability only, it does not refer to maximum
available lift force.

CAUTION
The load diagram below shows the tipping loads on a level
surface:
a) Tipping load with the loader frame in straight position.
b) Tipping load with the loader frame in maximum
articulation.
• ROC (Rate operating capacity), defined as 60 % of
tipping load for pallet forks.
Overload will cause the loader to tip
forward. Always pay attention to safe
operating conditions whenever lifting
loads or handling heavy attachments.

Rated operating capacity (ROC)
The loader In max. articulation
Driver 75 kg
The lifting capacity and the stability of the loader are at the
best, when:
• the loader frame is kept straight
• the centre of gravity of the load is as close to the loader
as possible
• counterweights are fitted to the loader
• swinging of the load is prevented and all controls are
used in a calm and careful manner
Example: If the centre of gravity of the load is 750 mm
in front of the front axle (400 mm from the pallet forks at
ground level), the tipping load is about 470 kg with a driver
weighting 75 kg and with the articulated frame turned to
max articulation.
WARNING
If you leave the loader, tipping and max.
loads are reduced respectively. The
indicated load is the maximum load that
can be loaded on pallet forks and the
machine will not tip over, i.e. the weight
of the standard pallet fork attachment
(90 kg) is taken into account.

Avoid overloading the loader know the load and lifting capacity
of the loader. The diagram is valid
only on firm and level ground, with the
conditions listed above.
WARNING
22
400 Series
Rated operating capacity
To determine how much the loader can handle safely, a
table of the tipping load and a calculated Rated Operating
Capacity (ROC) is shown in the adjacent label.
A rated Operating capacity label is located near the driver’s
seat and can be read while you sit on the driver’s seat
Rated operating capacity depends on type of use of the
loader:
• In bucket and general application the rated operating
capacity is 50% of tipping load
• In pallet fork application the rated operating capacity is
60% of tipping load
The information shown in the table is the worst case
minimum load, with the conditions listed below. Actual lifting
capacity could be significantly higher, or it may be lower,
depending on terrain conditions, available lifting force, and
load distribution. Adding or removing counterweights will
affect the indicated ROC.
The ROC table is valid, when:
• The ground is firm and level
• Loader is stationary or driven max 2 km/h, with smooth
and slow control movements
• Driver 75 kg is seated on the driver’s seat
• Load is distributed evenly on pallet forks, with the load
centre of gravity at 400 mm from the vertical part of
pallet fork arms. The weight of the fork attachment is
taken into account in the indicated load values

Battery disconnect switch
Installing of service support
The loader is equipped with a
battery disconnect switch. The
switch is located in the rear of
the machine, on the right side
(see picture). Always switch off
main current when you leave the
loader unattended, and before
you do any maintenance or inspections. Switching the
battery disconnect switch to position OFF (horizontal
position of the switch key) will isolate the battery from the
electric system of loader, and will prevent hazards related
to damaged electric wires, short-circuit, and overheat of
electric components.
WARNING
The red service support of the
boom lift cylinder is located at
the tip of the boom, behind the
attachment coupling plate.
Make sure that the boom
stays up during maintenance
operations by attaching the
service support on the lift
cylinder piston rod. Secure the
service support by locking it
on the piston rod with the long
screw that is on the support.
Risk of fire - Always switch off main
current when the loader is not used.
Turn the battery disconnect switch to
position OFF whenever leaving the
loader unattended or before servicing
the machine. If left on, there is a risk
of sparks and short-circuit during
maintenance and if any electric
insulator is faulty.

Operating instructions
Drive release valve (option)
Anti slip valve (option)
The switch with the text LOCK
controls a valve, which is used to
divert the oil flow between left and
right side hydraulic motors. 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.
The anti slip 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 in dashboard. As soon as
the switch is released, anti slip valve is released.
The function of the anti slip valve depends also on the
position of the drive release switch.
X-lock OFF: The anti slip valve equalizes the oil flow
between the left and right hydraulic motors, but some
oil will pass between the left and right side of the loader
through the open X-lock valve.
X-lock ON: The anti slip valve equalizes oil flow between
the left and right hydraulic motors - all four wheels spin
equally and provide the best possible traction.
Parking brake handle
Avant 423 is equipped with a
mechanical parking brake. The
parking brake is operated with
handel under the steering wheel.
• Locking: pull the handle and
turn down into locking position
• Releasing: turn up and let the
handle go down
Parking brake locks mechanically - spring-loaded 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.
CAUTION
Risk of sudden stop - Do not engage
the parking brake when the machine
is moving unless in emergency.
Using the brake while moving may
cause the locking of wheels and
sudden stopping of the machine.

Loader control
Boom floating (option)
The loader boom and bucket are controlled with the multifunction lever sideways (tilt) and back & forward (boom up
& down).
The floating system releases the lift cylinder to allow it to
move upwards. This will allow the attachment to follow the
contours of the terrain, making grading and leveling work
easier. The boom can move upwards from the position
where the boom floating is switched on.
• 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)
1. Lower the boom down. With some attachments and work
tasks, it may be useful to press down the attachment
before you switch on the floating.
2. Switch on the floating with the
switch on the dashboard, see
page 24
3. Boom floating indicator on the
dashboard lights up
For details about how to operate the loader with different
attachments, refer to the Operator’s manual of each
attachment. For example, instructions regarding the use
of a bucket are shown in the operator’s manual of bucket.
NOTE: The switch is installed on the dashboard, also
in cases the boom floating option is not installed on the
loader. The presence of the switch does not mean the
boom floating is fitted.
Telescopic boom (option)
The telescopic boom makes many
tasks easier, also those that do
not involve lifting. You can, for
example, push material further with
a bucket, reach into difficult areas,
and improve visibility to the work
area with some attachments.
Telescopic boom is operated with
the control lever on the control
panel (see page 25). Turn the
control lever of the telescopic boom
to the right to extend the boom, and
turn to the left to retract it.
Length of the telescope is 600 mm
and additional lifting height is 485 mm.
WARNING
NOTICE
NOTICE
Risk of tipping over - Extended
boom can cause the loader to
tip over. Use telescopic boom with
caution. The stability of the loader
depends on the distance of the load
from the front of the loader. When you
extend the boom, you increase the
effect of the weight and reduce safe
handling capacity. See pages 22 and
50 for further instructions about tipping
load and safe material handling.
WARNING
30
The floating releases the boom to
move up from the position from where
it is switched on. Lower the attachment
firmly on the ground before you switch
on the floating. In some tasks, it may
be useful to press the attachment
down so, that the front wheels of the
loader lift off from the ground.
Some attachment have a floating
linkage built in the attachment coupling,
making use of the floating on the loader
unnecessary. Refer to the operator’s
manual of the attachment for more
information.
Risk of lowering of the boom when
switching on boom floating - Lower
boom to close to the ground before
switching on boom floating. Switch
on the boom floating only when
stationary and when the load is close
to the ground. Boom can move down
when you switch on the boom floating.
Keep the boom floating switched
off during normal use of the loader,
especially when lifting loads with the
loader.
400 Series
Operating instructions
Tilt adapter (option)
Side shift adapter (option)
A hydraulic tilt adapter can be
mounted between the attachment
and the attachment coupling
plate. It makes it possible to tilt
the attachment sideways from the
driver’s seat.
A side shift adapter is a coupling
bracket that makes it possible to
operate an attachment off the the
centerline of the loader. There are
two kinds of side shift adapters
available (as of 5/2018):
• Fixed side shift adapter models
• Hydraulic side shift adapter
• Tilt adapter A34148, tilting angle ±12.5°
• Tilt adapter A36505, tilting angle ±45°
• Rotating adapter A424406, continuous 360°
Tilt adapter is intended mainly for non-hydraulic
attachments. With the optional double acting extra
auxiliary hydraulics outlet in the front it is possible to mount
a hydraulically operated attachment (e.g. a 4 in 1 bucket)
at the same time.
See the operator’s manual of each attachment for
recommendations about the use of the tilt adapter.
Tilt adapter is operated with the auxiliary hydraulics control
lever. If the tilt adapter is connected to the optional extra
auxiliary hydraulics outlet in the front, see page 33 in this
manual for instructions about use.
NOTICE
WARNING
Tilt adapters increase the distance
of the load from the loader, thus they
decrease the tipping load of the loader.
Use tilt adapters only when needed to
complete specific tasks.
31
Risk of tipping over - A side shift
adapter decreases the sideways
stability of the loader significantly.
Use all adapters only for specific tasks,
as instructed in the operator’s manuals
of each attachment. Remove all
adapters for general use of the loader.
Adapters decrease lateral stability of
the loader and must be used only on
level ground.
Operating instructions
400 Series
Using the auxiliary hydraulics
NOTICE
Auxiliary hydraulics (hydraulically operated attachments)
are controlled with the control lever on the control panel
front from the joystick, or with the optional auxiliary
hydraulic control buttons on the joystick. The lever locks
in the locking position which facilitates operation of the
attachments that require constant oil flow to operate (rotary
broom, backhoe etc.).
Make sure that the auxiliary hydraulics
control lever will lock in its fully
engaged position when locked on.
Even a slightly incorrect position is
enough to decrease the effectiveness
of the hydraulic system, and will cause
overheating of the hydraulic oil. Adjust
the locking plate if needed.
Joystick with auxiliary hydraulics control
buttons (option)
DANGER
The loader can be equipped, as an option with the 6 function
joystick, where the operation of
auxiliary hydraulics is controlled by
push buttons.

400 Series
Operating instructions
Drive control
WARNING
Avoid collisions - Practice the use of the loader at a safe area. Familiarize yourself
with the driving of the machine on low speed and on a flat, even and open place where
unintended movements will not cause collisions or danger to yourself or others. 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 423 is equipped with a hydrostatic drive system. In the drive circuit there is a
variable displacement hydraulic pump that is proportionally controlled with the two drive
pedals.
Driving of the machine is controlled with the drive pedals and hand throttle.
• Select the engine speed with the hand throttle lever on the control panel
• Control desired driving direction and speed with the drive pedals
• To get the maximum pushing power push the pedals lightly – for higher travel speed
push the pedal harder
WARNING
Risk of loss of control and rolling over of the loader - Reduce
speed before sharp turns and when driving on uneven terrain.
Abrupt control movements can tip the loader over. Do not turn
the steering wheel quickly when you drive at high travel speed. Drive
slowly whenever carrying loads, driving on inclined or rough terrain,
or on slippery surfaces. Always reduce speed before sharp turns.
Drive control
• 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 basic rule is: use lower revs for lighter work and higher revs for hard work or for
high travel speed.
The hand throttle can be used to control engine speed also while driving.
NOTICE
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 RPM
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 RPM and push pedal only a little.
37
Operating instructions
400 Series
Allow the loader to warm up properly
Steering of the loader
Hydraulic oil temperature has an effect on the hydrostatic
drive system of the loader. When the ambient temperature
is below 5ºC, make sure the general response to drive
pedals is normal. If the drive feels sluggish, allow the
hydraulic system to warm up by letting the auxiliary
hydraulics pump to run at idle. Drive carefully until the
loader has reached its normal operating temperature.
Steering of the loader is controlled with the steering wheel.
The steering system 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.
Pay attention to other machines and persons that are
moving in the area. Make sure that there are no persons
in the danger zone of the loader and the attachment. The
danger zone of the loader covers the reach area of the
loader boom, the turning area on the side and in the front
and rear of the loader. Always put down the load when
leaving the machine – the loader is not designed to stay
with the loader boom and load lifted. Learn how to operate
the loader in a safe place.
WARNING
Risk of decreased braking power
- Make sure hydraulic oil is not
overheated. When hydraulic oil gets
hot, driving characteristics of the drive
system change. When the oil is hot and
the hydraulic oil cooler has switched
on, stopping distance of the machine
can be longer than when the machine is
cold. If the loader is used constantly in
high ambient temperatures, hydraulic
oil type and viscosity must be suitable
for these conditions. Contact Avant
service.
DANGER
In case the braking power of the
hydrostatic
drive
system
has
decreased, engage the parking brake.
The rear wheels may lock immediately.
Parking brake acts as an emergency
brake, and will also engage in case of
loss of oil pressure. Parking brake is
intended to keep the loader stationary
and not for repeated braking. Engage
while loader moves only when
necessary.
DANGER
WARNING
CAUTION
38
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.
Risk of tipping over - Keep load
close to ground. 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.
Risk of tipping over - Keep load
close to ground. 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.
Risk of collision and crushing.
Remember that when turning, the
driver´s seat extends beyond the
turning radius of the wheels. Stay
inside the safety frame.

Refueling
1. General condition of loader
Check the fuel level and fill the tank if necessary. Make
sure to add fuel before the fuel tank gets empty. If possible,
refuel the loader after use to prevent condensation of water
into the fuel tank.
Use only ultra low sulfur diesel fuel. Use of other fuels is
not allowed, as the operation of emission control systems
and the engine injection system are dependent on clean
and high quality fuel.
• Check the metal parts for damages or rust.
◦ Do not use the loader if you see damaged, bent,
corroded, or deformed metal parts. Contact Avant
service for service, if necessary.
• Ensure all safety decals are in place and legible.
◦ Never operate loader if safety decals are damaged or
missing. Replace safety decals when needed.
• Check the underside of the loader and ground for
leakages. Also check ground/floor surface for signs of
leakage.
WARNING
NOTICE
◦ Never operate, if leakage is observed. Repair all leaks
before use. Clean all leakages.
Always stop the engine and allow it to
cool before refueling. Do not spill fuel
when refueling. Should this happen,
wipe the fuel away immediately in order
to avoid risk of fire. Keep fuel away from
sources of ignition. Do not smoke during
refueling.
• Check the condition of the safety frame, seat belt,
lamps, and other safety equipment:
Use only clean fuel and take care
when refueling the loader to avoid
dirt and water from entering the fuel
tank. Clean fuel cap and surroundings
before opening the cap. Always store
fuel properly in an approved container.
Water in fuel can cause severe damage
to engine injection system.
◦ Make sure all lighting devices are functional and
clean.
◦ Safety frame (ROPS) and protective roof (FOPS)
must be fitted.
◦ Safety structures must not have visible damage or
deformations. They must be replaced with new ones
after any incident.
◦ Check operation of reverse beeper (if installed).
Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed. Check fuel system
thoroughly and clean the fuel tank after every 2 years.
If you run out of fuel:
Add recommended type of diesel fuel from a clean
container. Switch on ignition key of the loader to position
ON, but do not start. Allow the electric pump to circulate
fuel for a couple of minutes before you start.
If you are running low on fuel and operate the loader on
tilted ground, the loader may stall as fuel flow to the engine
may be temporarily interrupted. Add fuel to prevent stall on
uneven surfaces.

Daily inspections and maintenance
2. Cleaning of the loader
Clean cooling systems
Pay special attention to the cleanliness of the engine
compartment and engine bay, battery, and radiators.
A dirty machine will run hotter and can cause poor
performance, shorter battery life, or stopping of loader
due to overheating.
There are two cooling fans on the loader:
Cleanliness of the loader is not only a question of outer
appearance. All surfaces, painted and others, will stay in
better condition when they are kept clean.
Keep all lights, windows, and mirrors clean to ensure
visibility.
• Hydraulic oil cooler
• Engine cooler
Keep both coolers clean to ensure reliable operation and
long service life of the loader.
If you operate the loader in dusty conditions, clean the
cooling fans and surfaces more frequently.
NOTICE
You can wash the outer surfaces of the loader carefully
with a pressure washer. Never use the pressure washer
to clean the inner parts of the loader or the battery,
electric parts may become damaged. Wash hydraulic
components (hoses, fittings, cylinders, valves), any
electric component, decals, and the radiators carefully,
never with a high pressure washer.
NOTE: There is a service hatch on the underside of the
loader to help the cleaning of the rear frame. Reinstall
the cover plate after cleaning to protect the internal
components of the loader.
NOTICE
NOTICE
Clean the cab interior with an appropriate mild detergent
and cleaning supplies.
After washing with a pressure washer grease all greasing
points.
NOTICE
Never spray the engine compartment
or radiators with a pressure washer.
Cooling radiators and electric
equipment, their connectors and
insulators, and the battery may get
damaged. Use cool or warm water to
wash other parts of the loader. Never
use hot water (above 70ºC).
49
The loader is equipped with a hydraulic
oil cooler, which is located at the right
side of the loader, near the controls of
the loader. Make sure to clean the oil
cooler cell with compressed air every
time you are servicing the loader - and
even more frequently if the loader is
operated in dusty conditions.
Proper cooling is essential. To prevent
overheating, clean screens, cooling
fins, and external surfaces of electric
motors, inverters, and the charger.
Avoid spraying water at wiring harness
or any electrical components.
If the loader is equipped with air
conditioning: A condeser of the air
condition unit is installed on either on
the roof of the loader, or behind the rear
window. Clean the condenser carefully,
never with high pressure washer or
with high pressure air gun.

3. Greasing of the loader
Greasing of pivot points is very important to avoid wear.
Most of the greasing points are on the loader boom. The
following table and pictures show the location of grease
nipples.
1
2
Suitable lubrication interval depends heavily on operating
conditions. Check the need of lubrication at least after
every 10 hours of use. Add grease if the joints have
become dirty. Adequate lubrication of the joints must be
ensured. Lack of lubrication will cause the joints to wear
quickly.
3
Use general purpose machine grease. A grease gun is
needed to apply grease to grease nipples. All lubrication
nipples are standard R1/8” nipples. Replace any
damaged nipples.
3
Clean the end of the nipple before greasing and add only
a small amount of grease at a time. New lubricant will
push out dirt from joints. Wipe excess grease with a cloth.
