1. SAFETY INSTRUCTIONS
WARNING Reed carefully the information in the manual and on the machine,
before you operate or assemble the machine.
In addition to the safety instructions in this list, take care of all general safety rules for
machinery work.
The use of this machine is allowed only for a person familiar with the functions of the machine
and with the manual. The operator must also be mentally and physically capable of operating
the machine safely.
The user shall wear suitable close tting clothing and avoid wearing other items that could
increase the risk of get stuck in the machine.
The ELHO V-Twin is hydraulic driven. Take therefore particular care before any work on the
machine as there might be full power also behind stopped or blocked rotors!!!
Before you leave the tractor cab the tractor engine has to be fully stopped and the parking
brake engaged. This to ensure no hydraulic power is applied to the rotor drive.
Before the baskets are started, make sure that no loose parts or tools are beneath or on the
machine. Keep bystanders, particularly children away.
All maintenance and adjustments is to be carried out with the tractor engine stopped.
Do not work under the machine if it is supported only by the tractor hydraulic controls.
You must not allow people to stand near the machine when it is being used. Danger from
particles thrown by the machine’s tines.
Check daily that the joints and arms of the wheel linkage are undamaged and secured, wheel
nuts are tight. If a wheel is lost during transport a serious accident may occur.
Great care must be taken during transport on public roads. Ensure that the mechanical locks
for the basket are closed bout sides. Reduce speed when turning and driving on uneven
ground.
Use only original ELHO spare parts. The machine’s construction must not be changed and
the machine must only be used for mowing and swath laying grass crops.

1.1. Intended use
The ELHO V-Twin 750 Rake is designed solely for use in raking agricultural hay or grass or
straw crop into a windrow. The use for other purpose is strongly forbidden.
1.2. Tractor and machine noise
EC Directive 86-1888-EEC and UK Noise at Work Regulations 1989 place responsibilities on
employers and employees to assess and control noise at the workplace.
Bystander noise level of the ELHO V-TWIN 750 can exceed 87 dB (A) particularly if operated
at full speed in an enclosed space.
We recommend that the machine should not be run at full speed in an enclosed space and
that if it is necessary to approach the machine, that hearing protection is worn.
Noise level during normal eld operation will vary depending on the noise of the tractor and
how the tractor is operated. In some instances the tractor, whilst operating under load and
normal speed will produce the highest noise level.
The approximate noise at the driving position generated by the ELHO V-Twin 750 with tractor
cab windows open is in range 80-96 dB (A) and occurs with the machine out of work and
raised. The noise level from the Rake is normally reduced in work.
Radios are also a source of noise.
The comments on noise level are given for guidance only and each combination of tractor
and machine should be assessed.
1.3. Manual handling- Components
EC directives 89/391/EEC and 90/269/EEC and UK Manual Handling Operations Regulations
1992 place responsibilities on employers and employees to operate safe working practices
when manually handling heavy weights.
When assembling the machine heavy components must be handled with a mechanical lifting
device. Some parts might need two persons for the assembly.
When carrying out repairs to the machine the following parts should be lifted with mechanical
equipment; drawbar; main frame; baskets and basket rotor units.
Depending on working conditions other components may require 2 persons to handle them.
1.4. Warning signs
This mower conditioner manual contains clearly marked warnings which are intended for your
personal safety and contain important advice for use of the mower.
WARNING Warning! Indicates the presence of a hazard which could result in
personal injury.

2.2. Paint
To ensure a long lifetime of the ELHO machines also the paint and painting process used at
the manufacturing full most strict international painting standards. However also a god paint
surface might be damaged or scratched during transport and use.Paint in correct colour is
normally most easily accessible at your local paint shop, As post and parcel transport of paint
is restricted by very strict safety rules.
If you notice the following international colour numbers used for the original painting of the
ELHO machines it will help you to get the right shade. The original paint is a polyurethane
based industrial truck paint but an alkyd based paint of god quality is also suitable for paint
repair.

1514
• Ensure that the machine is correct assembled and not damaged.
• Check that all greasing points are well lubricated.
NOTICE
Note particularly that the hydraulic hoses are correctly connected
to the tractor, in particular the free return. Otherwise there is a risk
of damages to the seals of the hydraulic motors.
• Release the transport hooks A of the baskets and lift the baskets slowly up (activate
section for hose nr. 5).
• Take care nobody is in the danger zone and
swing the baskets out (activate double acting
section for hoses nr. 1 &2) .
• Let the baskets down to the ground.
3. STARTING UP A NEW MACHINE
It is important that the greatest care is taken when starting up a new machine. Incorrect
assembly, wrong operation etc. may cause damage, which is not covered by the ELHO
warranty.
The ELHO V-Twin 750 is connected to the 3-P linkage of the tractor (Kat II ).
See § 5 Connecting to the tractor

1716
Check that the rake tines are at least 5 cm free from
ground.
Check by rotating by hand, that the baskets are free
to rotate, and that no tines, tine bars or tine guides are
bent or damaged.
The basket wheel should rotate freely with a minimum
of noise.
Start the tractor and engage slowly oil to the baskets
(activate section for hose nr. 3). The baskets shall
rotate smoothly and with a constant speed.
Check and re-tension if necessary all bolts and nuts
after approximately two hours of use.
Particular important this is for the wheel bolts.

Tightening torques
Do a check of all hex screws and nuts regularly, tighten them if necessary. If nothing
special is mentioned, use the tightening torques seen on the table below:

1716
4. ASSEMBLY
The ELHO V-Twin rakes are generally delivered assembled and tested from the
factory. Therefore no assembly work should be needed. Just check that the machine
is delivered without transport damages.
It’s important to check the received machine compared to the order concerning the
equipment’s.
Check the pressure in the tires (1,6 bar) and the torque for the wheels (235Nm).
To lower the transport costs the wheels are often dismounted. Furthermore from the
torque it’s recommended to check the alignment of the steering axle according to the
picture below. The correct alignment is important to prevent unnecessary wear of the
tires.
The alignment setting is done with the rod end A as the picture show.
If the machine is not aligned with the tractor when driving straight forward use the
setting in rod end B to corrects this.

1918
5. CONNECTING AND DISCONNECTING TO THE TRACTOR
The connecting and disconnecting to the tractor should only be carried out on at ground.
Ensure the surface is has enough stability to carry the load of the support leg.
Disconnecting
Lower the support by pulling it rmly in the direction of the arrow
and turn it down.
Lower and dismantle the linkage arms. Do not forget to
disconnect the hydraulic hoses and the rope to release the
transport hooks.
Connecting
The connecting to the tractor is done in opposite way. Do not
forget the side support stabilisers of the lift arms!
Connect the hydraulic hoses. Start with ensuring a good
connection for the free return line.
Required oil ow 25 litre/min, oil pressures 175 Bar, max. 210 Bar. Max oilow 50 litre/min.
NOTICE
The ELHO V-Twin rake is equipped with hydraulic couplings according to
ISO 5676. It is unfortunately common that hydraulic quick-release couplings
on different brands do not always suit each other to 100% although they
are made to the same nominal size and mechanically t in each other.
Their spring loaded cones may not fully open and particularly by increased
oil ow the return line may suddenly close if matching connectors is not
used..

1918
6. ADJUSTMENTS
6.1. Raking height adjustment
Normal setting is tine end 5 cm above the ground. Keep the
setting as high as possible while still picking up crop.
To set the initial raking height:
1. Open the rake on a level rm surface.
2. Ensure the caster wheels are in trailing position.
3. Rotate the baskets by hand to bring the tine bar B in the
lowest position.
4. Adjust the raking height with the spindle A of the caster
wheels.
5. Check both sides & front and rear are at equal level.
6. Secure the spindle A.
6.2. HydroBalance adjustment
During work the weight of the rake baskets are mainly
carried by the HydroBalance pressure stored in the nitrogen
accumulator. This pressure is factory set to approximately
100 bar.
If the pressure is too high it will be difcult to get the baskets
down to work position.
If the pressure is to low the caster wheels are hard on the
ground and the baskets tend to “drag” and jump.
To adjust the pressure loosen the counter nut of the screw D
and screw it in to increase the pressure and out to lower the
HydroBalance pressure.
Note, that the pressure do not change immediately. You have
to lift and lowered the baskets once before the new pressure
level is reached.

2120
6.3. Swath width
The swath width is set by crank E.
Adjust left and right hand baskets to
equal width.
Do not mowe the baskets more in than
that the rubber bumper still is outside
the elbow F. Risk of interference
between the hydraulic motor and the
frame.
Note that the swath width adjustments
also inuence on the working width.
6.4. Working width
The working width can be innitely adjusted
by folding the baskets in or out by the
hydraulic cylinder.
6.5. Crop Throw adjustment
The throwing angle of the baskets are set by the adjusting the
length H of the spring bar.
The factory setting is about 85 cm.
Generally the length H can be slightly increased in green crops and
decreased in dry light crops.
Remember to set all spring bars to the same length and secure by
tightening the counter nuts rmly.
