Paint
To ensure a long lifetime of the ELHO machines also the paint and painting process used at the
manufacturing fulfil 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.

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 field 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
engine 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.
We recommend that the tractor is operated with the cab windows closed.
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.
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 or when carrying out repairs the machine all heavy parts must be handled with
a mechanical lifting device.
Depending on working conditions some components may require 2 persons to handle them.

2. Safety instructions
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 fitting 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.

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.
Ensure that the machine is correct assembled
and not damaged.
Check that all greasing points are well
lubricated.
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.
Stop the tractor!

VTwin - 750
14
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.
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.

5. Connecting and disconnecting to the tractor
The connecting and disconnecting to the tractor should only be
carried out on flat ground. Ensure the surface is has enough
stability to carry the load of the support leg.
Disconnecting
Lower the support by pulling it firmly 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.
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 fit in each other. Their spring loaded cones may not fully open
and particularly by increased oil flow the return line may suddenly close if matching connectors
is not used.
Required oil flow 25 litre/min, oil pressures 175 Bar, max. 210 Bar. Max oilflow 50 litre/min.

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:
•Open the rake on a level firm surface.
•Ensure the caster wheels are in trailing position
•Rotate the baskets by hand to bring the tine bar B
in the lowest position.
•Adjust the raking height with the spindle A of the
caster wheels.
•Check both sides & front and rear are at equal
level.
•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 difficult 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.

6.3 Swath width.
The swath width is set by crank E.
Adjust left and right hand baskets to
equal width.
Do not mow the baskets more in than
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 influence on the
working width.
6.4 Working width .
The working width can be infinitely
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 75 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 firmly.
a

6.6 Basket speed
The basket speed is adjusted with the oil flow divider A.
Normal basket speed is 80 - 100rpm.
The slower the speed, the more gentle raking.
Do not increase the basket speed over 110 rpm.
Risk for major damage to the tine bars.
7. Use of the machine
7.1 General guidelines for working with the machine
All work in the immediate area of the baskets may be carried out only with the tractor
engine stopped.
The rotors are hydraulic driven. Take therefore particular care before any work on the
machine as there might be full power also behind stopped or blocked rotors.
Choose the speed of travel so that all crops are picked up thoroughly.
- In cases of overloading, shift down one gear.
After the baskets are lowered for a new swath, check that the caster wheels of the basket take
their trailing position.
If joining swats, adjust the working width to avoid splitting up a swath.
If the baskets tend to block:
-Ensure the rake tines rotate clear of ground.
-Reduce the speed of travel
-Reduce the working width
-Adjust the length of the basket spring bar. Se § 6.5 Crop Throw adjustment.
-If the problem continue, check that the tractor hydraulics is working properly. Measure the oil
flow also under load at your tractor service.

7.2 Transport
For transport:
•lift the baskets to max. lift height.
•Fold the baskets fully in.
•Let the baskets down in the transport supports.
•Ensure bout transport locks A hooks in fully.
•Lock the support wheels in the travel direction by use of
the ring pin B.
Reduce the speed when turning and driving on uneven roads. Too high speed can create big
chock loads to the construction, which might result in damages to the wheel arms and frame (not
covered by the warranty). The maximum road speed for the ELHO V-Twin rake is 30 km/h.
Observe the local legislation for transport on roads. In certain countries it may be necessary
to equip the machine with a SMV triangle or rear lights and reflectors when driving on public
roads.

8. Maintenance
To ensure a long and trouble free use of the machine, keep the machine
clean and follow the maintenance instructions below.
It is particular important to keep the hydraulic oil of the
tractor clean and in god condition. Change the oil and the oil
filter according the tractor manufacturers instruction .
Check regularly all bolts and nuts and re-tighten when necessary.
Tightening moments (in Nm) if not especially mentioned are according to
the following list.
Remove possible grass remaining from the area around the basket
tine bar bearings. Dried dirt can damage the bearing seals. Avoid
the use of high pressure cleaner, since the high-pressure water jet
can penetrate into the labyrinth sealing of the bearing house.
Check the bearings straight after the season. Change if doubt, it will
save you problems during the season. The bearings are available
in kits of 14 Pcs. Order number: 418125.
On the inlet hose to the HydroBalance valve there is a small high
pressure filter to prevent dirt from the quick release couplings from
entering the sensitive regulator valve.
Normally this high pressure filter do not need any maintenance,
because the return oil from the cylinders normally clean away the
dirt.
If however the oil in the tractor is dirty, this filter might be blocked
and has to be replaced.
