1. Foreword

Avant Tecno Oy would like to thank you for your purchase of this AVANT attachment. It has been designed

and manufactured on the basis of years of product development and experience. By familiarising yourself

with this manual and following the instructions, you ascertain your safety and ensure the reliable operation

and long service life of the equipment. Read the instructions carefully before starting to use the equipment or

performing maintenance.

With these instructions, even an inexperienced user can use the pallet forks and loader safely. The manual

also includes important instructions for experienced AVANT operators. Ensure that all persons using the

equipment have received proper guidance and familiarised themselves with the manual and all safety

instructions before using the equipment. Keep this manual at hand throughout the service life of the

equipment. If the manual is lost, you can request a new one from the retailer or manufacturer. If you sell or

transfer the equipment, be sure to hand over this manual to the new owner.

2. Designed purpose of use

This AVANT pallet fork is an attachment designed and manufactured to be suitable for use with AVANT

multi purpose loaders. The pallet forks are mainly intended for handling standard sized pallets. With the fork

side shift mechanism, different pallet sixes can be transported easily. A load backrest extension is also

available, and it can be folded if extra overhead clearance is required. If lifting and load handling tasks are

frequent, equipping the loader with the boom self levelling and the electric joystick will make repeated lifting

tasks easier.

Pallet fork is an useful attachment all year round for example on construction sites, farms, and especially at

outdoor material handling jobs, where conventional fork-lift trucks are impracticable. When operating with

the pallet forks, the performance and stability limits of the loader must be observed, expecially when working

on inclined terrains. The pallet forks must not be used for lifting persons and it is prohibited to use the pallet

forks to lift any kind of access platform.

When lifting other material than pallets, the Log Grab attachment (A34822 or A33503), that can be fitted to

the pallet fork, is recommended. The log grab accessory makes it easy to handle single logs, smaller timber

bundles, fence poles, or similar material. The log grab is also suited for easy handling of tree branches and

bunches of twigs and also for moving large rocks. The handling of pallets is possible even if the log grab is

attached on the pallet forks, but the grapple limits the maximum height of the pallet.

The attachments have been designed to require as little maintenance as possible. Regular maintenance

tasks can be performed by the operator. Read the maintenance and servicing instructions in this manual.

Please contact your AVANT retailer if you have additional questions about the operation or maintenance of

the equipment or if you require spare parts or maintenance services.

3. Safety instructions for the pallet forks

Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly

powerful, and improper or careless use may cause serious personal injury or property damage. Due to this,

you should carefully familiarise yourself with the manuals of both the loader and the attachment before

starting operation. Do not use the attachment if you have not familiarised yourself with its operation and the

related hazards.

The purpose of these instructions is to help you to:

•use the equipment in a safe and efficient manner

•monitor and prevent any hazardous situations

•keep the equipment intact and ensure a long service life

4(12)

•When attaching the pallet forks to the loader, ensure that the locking pins of the

loader's quick attach plate are in the lower position and that they have locked the

attachment to the loader.

•Always transport the load as low as possible to keep the centre of gravity low. Heaviest

end of the load should be closest to the machine. The load should be balanced evenly

also sideways.

•Keep the forks at as wide setting as possible.

•Be careful when lifting load to high level or lifting load from high. Operate the controls of

the loader calmly and deliberately. When handling heavy loads avoid sudden changes

in speed or direction to maintain balance of the loader.

•Keep the loader articulation in straight position when handling heavy loads. When

turning the articulation, the loader may tilt forward.

•Observe maximum load indicated in the operator’s manual of the loader. Be especially

careful when the load sensor indicator is activated.

•Make sure that the surface can bear the total load. Also follow the correct tyre pressure

settings.

•Lift loads slowly and monitor the position of the forks, so that the load will not fall off.

Make sure that overhead clearance is sufficient.

•Never leave the driver’s seat when the forks have been elevated. Lower the boom on

the ground.

•The pallet forks or the loader are not intended to be left to keep a load elevated for

longer periods. It must be observed that the loader boom will lower by itself. Never go

under the raised load or the loader boom.

•Pay attention to the contours of the terrain and other hazards, such as branches and

trees reaching the driver's area. Pay attention to the surroundings and any other

persons and machines moving in the vicinity.

•The use of the pallet forks for lifting persons or as an access platform is strictly

prohibited.

•Shut down the loader before any maintenance or adjustments.

•Do not modify the structure of the attachment in a manner that would affect its safety.

Welding, drilling or any other modification of the pallet fork is prohibited.

•Also read the safety instructions for the loader in the loader manual.

Familiarise yourself with the loader controls in a safe area. Pay particular attention to

safe stopping of the loader.

Note that the loader boom moves down and may be tilted even if the engine has been

stopped. Never go under a raised attachment or the loader boom. Do not leave the

boom elevated.

Remember to wear proper protective clothing:

•The noise level in the driver's seat exceeds 85 dB(A). Wear hearing protection while

working with the loader.

•It is recommended to wear safety boots working with the loader. Also wear protective

gloves.

5. Putting the pallet forks into use

As the pallet forks are delivered, for easier transportation the frame and the forks may be separated. The

pallet forks can be easily assembled; tools are required only to tighten the bolts which lock the backrest

extension and theforks on the frame.

To install the log grab accessory, follow instructions given in its manual.

5.1. Assembling the pallet forks

To make the assembling of the forks easier, first attach and lock the

pallet fork frame on the loader quick attach plate. Attaching the frame

can be done manually or by placing the frame plate on suitable position,

so that it can be coupled with the loader, as described in the next

section. Note that the components are heavy, remember healthy

working habits.

After the frame plate is attached on the loader, you

can slide the forks to the frame. Drive the loader

next to the forks and tilt the loader front plate in

upright position, and set the boom height so that

the forks can be fitted. Note the locking mechanism

on top of the fork; it should be turned into its

upright position while mounting the forks. Make

sure that also the lower bracket is fixed onto the

frame.

Fitting the backrest extension:

The foldable backrest is fitted so that when

folded, the frame is towards the forks. Fit the

backrest extension with two screws from both

ends of the frame.

If the backrest extension will not be fitted:

The two screws delivered with the pallet forks

must be fastened to the holes at both ends of the

frame. The screws prevent the forks from

accidentally sliding off from the frame. Tighten

the bolts adequately.

7(12)

5.2. Attaching the pallet forks to the loader

Mounting the attachment to the loader is quick and easy, but it must be done carefully. An attachment that

has not been locked may come off the loader and cause hazardous situations. In the worst case, the

attachment may slide onto the driver along a raised boom. For this reason, the attachment must under no

circumstances be raised to a height of over one metre when it has not been locked. To prevent hazardous

situations, always follow the attachment mounting instructions provided in the following pages. Also

remember the safety instructions in Section 3 and the instructions provided in the loader manual.

The attachment is attached to the loader boom by using the quick attach plate and the counterpart on the

attachment as shown below. The locking on the loaders is semi-automatic, but it is recommended to lock the

locking pins manually.

Never move or raise an attachment that has not been locked.

Step 1:

•Lift the quick attach plate locking pin / locking

pins up and turn them backwards into the slot

so that they are locked in the upper position.

Step 2:

•Turn the quick attach plate hydraulically to an

obliquely forward position.

•Drive the loader onto the attachment. If your

loader is equipped with a telescopic boom, you

can utilise this.

Step 3:

•Lift the boom slightly – pull the boom control lever

backward to raise the attachment off the ground.

•Turn the boom control lever left to turn the bottom

section of the quick attach plate onto the

attachment.

•Turn the boom control lever further left so that the

automatic locking of the attachment triggers the

locking pins.

The automatic return of the locking pins is a useful feature, when mounting an empty attachment to the

loader. In other cases we recommend that you lock the pins manually.

Do not use the automatic locking of the locking pins at a height of over one metre.

If the locking pins do not return to the normal position when the front plate is tilted, do

not raise the attachment any more. Lower the attachment on the ground and secure

the locking manually.

8(12)

Before moving or raising the attachment,

ensure that the locking pins are in the

lower position and come through the

fasteners on both sides. Unlocked

attachment may fall on the boom or

operator and cause injuries.

6. sing the pallet forks

Check the attachment and the operating environment once more before starting to work. Quick inspection of

the equipment and the operating area before use are parts of ensuring safety and the best performance of

the equipment.

•Before use check that the pallet forks are intact and that all obstacles have been removed from the

working area. Remember correct working methods and avoid leaving the driver’s seat

unnecessarily.

•Check that the forks are fixed correctly on the frame and that the side shift of the forks has been

locked positively.

•Use the laod backrest extension whenever there is sufficient overhead clearance.

•Operate the attachment only from the driver’s seat.

•Ensure that the loader and the attachment are used in a safe manner and as intended.

•Do not use the pallet forks to lift persons or any kind of access platforms.

Ensure that bystanders are at a safe distance when operating the equipment. Do not

let anyone to enter danger area of the boom or to stay directly in front of the loader.

Also make sure that it is safe to reverse with the loader.

The handling charasteristics of an articulated loader differ considerably from a

standard fork-lift truck. Learn how to handle articulated loaders in tight spaces.

Separate practise and training may be required.

Check the condition of the pallet before lifting it. A pallet that is in poor condition or

broken may cause hazardous situations.

When lifting load from a high level, the loader could tip forward when reversing with the

loader. Do not reverse the loader while simultaneously dragging the load. Make sure

that the loader can handle the load being lifted.

Ensure that ventilation is sufficient when operating indoors. Do not operate the loader

in closed spaces regardless of the engine or fuel type. Exhaust gases may concentrate

to hazardous levels.

9(12)

Adjust the forks to as wide setting as possibleand avoid uneven horizontal load

distribution for the best horizontal stability. Adjust the forks so that the load is

distributed evenly.

The width between forks can be adjusted by turning the locking pins on top of the forks to the upright

position. Adjust the fork width in a way that the load is spread horizontally even to achieve the best possible

stability. Always lock the forks to the intended gaps on the pallet fork frame and ensure that the forks can not

move sideways.

If the loader is not equipped with the boom self levelling:

When lifting material to a high level, the front plate must be simultaneously tilted to

prevent the load from falling from on the loader or the operator. Fitting the loader with

the boom self levelling option makes the repeated lifting work easier.

6.1. Safe working load

A load diagram is presented in the instruction manual of the loader. With the diagram the load handling

capability of the loader can be evaluated. The indicated diagram applies when the centre of gravity of the

load is at 40 cm from the loader.

The lifting capacity and the stability of the loader are at the best, when

•the loader articulation is kept straight

•the centre of gravity of the load is as close to the loader as possible

•the telescopic boom is kept retracted during lifting

•lifting with the fork tips is avoided

In the table 3 shown below are listed the minimum safe working loads on hard, level surface, when the

telescopic boom is fully extended and the loader articulation is turned to its maximum. The values in the table

correspond with the Safe Working Load determined in standard ISO 14397-1. The indicated values are

applicable with standard counterweights.

Actual lifting capacity could be significantly higher, or it may be lower, depending on terrain conditions and

load distribution.

Table 3 – Safe Working loads as determined by ISO 14397-1

635 - 290 kg 270 kg

745 - 445 kg 415 kg

750 - 450 kg 420 kg

10(12)

Do not extend the telescopic boom, when the load approaches the lifting capacity of

the loader or when the load has been lifted high. When the load indicator of the loader

signals, lower the load calmly and retract the telescopic boom. Avoid sudden changes

in speed or direction.

If the maximum lifting height is required, extend the telescopic boom while the load is near the ground. This

way you can more easily monitor the limit of the loader lifting capacity.

6.2. Slope operation and uneven terrains

Extra caution is needed when using the equipment on inclined terrains and slopes. On sideways inclined

terrains the load should not be lifted high. Turning the articulation of the loader during lifting will affect the

stability of the loader and may lead to overturning of the machine. Use low speed and do not make sudden

changes in speed or direction. Operate the boom with careful and smooth movements. When transporting

goods in uneven terrains or slopes, ensure, that the load is secured on the pallet and the forks. Use load

securing straps when needed.

To prevent tipping the loader to forward, and to gain better weight distribution, drive with the loader so that

the heavier end of the loader is towards uphill. Keep the load as close to ground as possible and as close to

the loader as possible. Familiarize yourself with the handling of the loader in different operating conditions.

6.2.1. Operation with the tilt adapter

When stacking pallets on slighlty inclined terrains, the tilt adapter A34148 is an useful attachment (available

for loaders in 300-700 –series). The adapter is fitted in between the pallet forks and the loader coupling

plate. The adapter allows the load to be tilted ±12.5 degrees sideways. Read the instructions provided with

the tilt adapter. More information about the tilt adapter is available from your AVANT retailer or the AVANT

web pages at www.avanttecno.com.

7. Maintenance and service

Keep the pallet forks clean and store them in a way that they are not in contact with ground. Lower the pallet

forks on pieces of wood or a pallet. To clean the pallet forks a pressure washer and a mild detergent may be

used. Before long storage periods touch up the paint finish or oil the visible metal surfaces.

Use the fork side shift every now and then to prevent the jamming of the forks or the locking mechanisms.

Check that the side locking of the forks is intact and locks in the intended slots. To make the fork side shift

easier a suitable oil or grease may be used. Keep the frame securing bolts fastened. Contact AVANT

service for spare parts.

Repairing the pallet forks by welding is prohibited. Do not weld any hooks or similar to the forks or the frame.

The forks are forged, heat-treated steel, and welding will have an effect on their strength. If a fork gets bent,

the damage may be permanent and the fork may not be straightened without professional maintenance.

Replace any damaged fork with a new one.
