3. Safety and Environment.
3.1 General safety.
NOTE!!!
Make sure that all persons who work with and/or service the SAMON onion Loader have read this manual
and take the necessary precautions to protect their safety and the safety of others when they work with
the SAMON onion Loader.
Always bear the following points in mind when working with or on the SAMON onion loader.
•The SAMON Onion Loader may be operated, serviced and maintained solely by persons who are
familiar with the machine and with the necessary safety procedures.
•Always switch off the tractor's engine and remove the key from the ignition before carrying out
inspections of or maintenance on the SAMON Onion Loader.
•The SAMON Onion Loader contains moving sieve and conveyor belts that can trap body parts.
•For this reason, never come close to a SAMON Onion Loader while it is in operation.
•Always wait until the sieve and conveyor belts have stopped moving before approaching the machine.
•A hedgehog belt mounted at the back of the SAMON Onion Loader unloads foreign matter. Never
come close to the hedgehog belt while it is working.
•If the machine hits an object, then switch off the SAMON Onion Loader and inspect the machine for
damage before switching it on again.
•The SAMON Onion Loader contains several parts which are fitted with locking pins and safety cords
and/or chains. These must always be fitted to the machine.
•Damaged and broken safeguards and locking devices must be replaced immediately.
•Protective covers, sleeves and rubber flaps may never be damaged. Always replace them when they
are dented or cracked.
•Always use original SAMON parts: these are designed specifically for the Onion Loader.
3.2 Environment.
Protect the environment by always cleaning and servicing the SAMON Onion Loader on a hard, impermeable
floor.
NOTE!!!
Dispose of spent lubricant in an environmentally-friendly manner. We recommend that you collect spent
oil in a closed container and deliver the oil to a recycling center or a collection point. Never dispose of
spent oil by allowing it to run off into a ditch, drain, sewer or the soil.

4. Inspections before and during use.
WARNING!!!
Make sure that the tractor's engine has been switched off and the key has been removed from the ignition
before you carry out inspections of or maintenance on the SAMON Onion Loader.
4.1 Necessary inspections before using the SU2LS for the first time
•Make sure all steps from chapter 5 are carefully followed up.
•Check the length of the PTO shaft (see 4.2)
•Check that all the wheel nuts are properly fixed. Always tighten the wheel nuts with a big cross-
key. Tighten the wheel nuts again after using the machine for two hours. Repeat this step each
time a wheel has been disassembled.
•Check all points of 4.3.
4.2 Shortening the PTO shaft.
When the inspection before use reveals that the PTO shaft is too long then it can be shortened as follows:
•Connect the machine to the tractor.
•Position the PTO shafts so that they are as close as
possible to each other.
•Measure distance "A" of the PTO shafts.
•Measure distance "B" of the PTO shafts
(see the illustration for the measuring points).
•Subtract length "A" from length "B" and add 10mm.
•Shorten the PTO shaft by the result (see example).
Example of a calcuation:
A=400 mm
B=450 mm
B(450) - A(400) = 50 + 10
To be shorened by 60 mm

4.3 Necessary inspections before each use.
•Check that the machine is correctly connected to the tractor as explained in chapter 5.
•Check that the return of the machine is connected to a pressure-free return of the tractor (see
5.1.1).
•Inspect the tow-ring for damage.
•Inspect the lighting and reflectors for damage.
•Check the oil level of the oil tanks (see 6.2)
•Inspect the gearbox for leaks.
•Inspect the complete hydraulic system for leaks.
•Inspect the electronics for damage.
•Inspect the tyres for damage and check the tyre pressure (2.5 bar).
•Inspect the protective cover of the PTO shaft for cracks.
•Check that the safety chains of the PTO shaft are fitted.
•Check that the locking clips and safety cords are in place.
•Inspect all protective covers for damage.
•Inspect the sieve, hedgehog and conveyor belts for damage and wear.
•Inspect drive and guide wheels for wear.
•Check that the wheel’s locking bolts are tight.
•Check that the conveyor belt is neatly between the flanges of the rollers (see 5.5.4).
4.3 Inspections during use.
•Check that the intake is at the right depth: it should enter the soil to a depth of 1 á 2 cm. If the
onion loader is equipped with a rotating bar the rotating bar should be in the soil for about ¾ (see
5.6.2)
•Check to make sure that the onions are not damaged.
•Check the adjustment of the hedgehog belt (see 5.7).
•Check the wheel track (see 5.2).
•Check that the intake plates are adjusted correctly.
WARNING!!!
The speed at which wearing parts wear depends on the type of soil. For this reason, the wearing parts
need to be inspected regularly to avoid damage to the SAMON Onion Loader.

5.5.2 Working position.
The main cylinder ant top part cylinders can be used to adjust the height of the conveyor when loading onions.
Never use the middle part cylinder when the conveyor belt is on.
5.5.3 Operating the conveyor belt.
The conveyor belt can be turned off independently from the sieving belts and the speed can adjusted by an
infinitely-variable potentiometer on the remote control.
Operation
Turn conveyor belt on.
Put switch 4 in top position.
Turn conveyor belt off.
Put switch 4 in bottom position.
Speed up conveyor belt.
Turn potentiometer 5 clockwise.
Reduce speed conveyor belt.
Turn potentiometer 5 anticlockwise.
5.5.4 Align conveyor belt.
When the inspection before use reveals that the conveyor belt is not neatly between the flanges of the rollers
it can be adjusted as follows.
•Disassemble the protective cover on the left side of
the machine.
•Loosen locking nuts (A) on the bottom of the tube.
•Adjust the position of the rollers until the desired
position has been reached.
•Tighten locking nuts (A).
•Assemble the protective cover.
5.6 Intake.
5.6.1 Operating the intake.
The intake operated as follows.
Operation
Machine
Lower
intake.
Move joystick 8 downwards: which
remains in this position. Always keep
the joystick in the bottom position
when loading onions.
Raise
intake.
Move the joystick 8 upwards until
intake stops.
5.6.2 Adjusting the height of the support wheels.
The dept of the intake is set by adjusting the height of the support wheels. Turn the spindles on the top of the
support wheels until they are in the required position. The sieve belt should enter the soil to a depth of 1 á 2
cm. If the loader is equipped with a rotating bar the rotating bar should be in the soil for about ¾. The correct
depth can vary with the type of soil.
NOTE!!!
Make sure that the conveyor is folded out completely before the conveyor belt is turned on. Starting the
conveyor belt while it is still folded in will damage the SAMON onion loader.
