2.2 SAFETY DURING OPERATION OF THE MACHINE
Owing to their high degree of inflammability, fuels are particularly dangerous. Improper use can
cause serious damage to personnel and materials. Always observe the following safety
regulations:
•Do not operate the machine inside a building or closed area without adequate ventilation.
Failure to comply with this regulation may lead to intoxication from carbon monoxide with loss
of consciousness, and even death.
•Before filling the fuel tank, stop the motor and leave it to cool down for a few minutes.
•Smoking is prohibited while the machine is in operation, or being refueled.
•Do not refill the tank near an open flame and remember to always refuel in an area that is well
ventilated.
•If the fuel tank is not airtight, it should be replaced immediately, since it could lead to
explosions.
•If any fuel is spilt while refueling, spread sand over the area. Change your clothes if any fuel is
spilt on them.
•Make sure that the fuel tank is closed properly after refueling.
•Check that there are no cracks or leaks in the pipes or fuel tank.
2.3 SAFETY DURING SERVICE
•Do not clean or inspect the equipment during operation.
•Do not start the motor up with the cylinder flooded or if the spark plug in the petrol motors has
been removed.
•Do not inspect the igniter plug to see if it is sparking correctly if the cylinder is flooded with

5 STARTING, OPERATION AND MAINTENANCE OF THE
MACHINERY
5.1 BEFORE STARTING WORK
5.1.1. The mechanisms of this machine are lubricated by means of an oil bath. Check the oil
level using the visor situated at the rear beneath the bellow. If oil cannot be seen through the visor,
add oil until half the visor is covered.
5.1.2. Fill the fuel tank with the appropriate type of fuel for the engine your machine is provided
with, according to the table below:
ENGINE TYPE
ROBIN ECO8 ROBIN EC12D ROBIN EH09 ROBIN EH12 HONDA GX120DKR
MIX WITH 4% CON ACEITE MINERAL
MIX WITH 2% CON ACEITE SINTÉTICO UNLEAD PETROL GAS-OIL A
2 TIEMPOS 4 STROKES DIESEL
TYPE OF FUEL
Use a high-quality fuel specially designed for 2-stroke engines, or if not, use a mixture of petrol with
synthetic oil specially for this purpose in a proportion of 50:1. When filling the tank, be sure to filter
the fuel with a strainer. Do not forget to replace the fuelling cap and close it. Failure to do this is
dangerous, as the vibration of the machine may cause spillages of fuel that then ignite and burn.
5.1.3 Be sure to check the tension of every bolt, nut or threaded area. A screw that has come
loose due to vibration may unexpectedly cause a serious problem. Make sure that all screws are
tightened.
5.1.4. Remove all dirt and dust. Pay special attention to cleaning the area adjacent to the
starter and the leg.
5.2 STARTING UP THE MACHINE
5.2.1. Open the fuel tap by moving the air regulator lever downwards, and put the choke valve
lever in the half-open position. To start the engine cold, move the air regulator lever to the closed
position. When the engine is hot, the air regulator should be half-open or completely open. If it
proves difficult to start the engine, make sure that the air regulator lever is half-open to prevent the
carburettor from flooding due to excess fuel.

5.2.2. When pulling the starter rope, do not apply full pressure for the whole length, as this may
damage the spring. Do not suddenly release the rope in order to repeat the process once the engine
has started. Hold on to the rope, and slowly release until it has fully returned to position.
5.3 OPERATING THE MACHINE
5.3.1. After starting the engine, gradually re-open the air regulator lever completely. Allow the
engine to warm up at minimum velocity for a period of 3 to 5 minutes. This procedure of warming up
the engine at a minimum revolution level is particularly important during the cold period. While the
engine is warming up, carry out a general revision of the machine to make sure that there are no
anomalies.
5.3.2. The piston starts to operate when the accelerator lever is turned with a rapid movement a
quarter of a revolution. If the lever is moved slowly, the action of the rammer will be irregular,
possibly causing damage to the clutch, the spring and the leg.
5.3.3. After the machine has started to operate, adjust the movement of the vibration in such a
way that it conforms to the particular condition of the ground, using the accelerator lever slightly as a
control. This rammer has been designed in such a manner that when the engine works at a velocity
of between 3,600 and 4,000 r.p.m., its leg hits the surface of the ground at a rate of 600 to 700 times
per minute, thus ensuring the greatest efficiency of performance. An unnecessary increase in the
velocity of the engine does not produce any increase in the force of compaction. Instead, the
resulting resonance causes a reduction in the compaction force, damaging the machine.
5.3.4. In cold weather, as the oil in the machine is viscous, the resistance in the alternating part
is greater, producing a somewhat irregular movement in the compacting rammer. For this reason, it
is recommended that the machine should be run for a while before starting work to warm it up,
moving the accelerator lever repeatedly between the positions 0 and ¼ turn.
5.3.5. The surface of the leg in contact with the ground is covered with a thermally treated
metallic plate. Nonetheless, for the compaction of boulder it is advisable to use a filling of fine
material such as sand so that the rear end of the leg's plane surface makes contact with the ground.
5.3.6. The compacting rammer has been designed to advance as it vibrates. To speed up the
rate of advance, raise the machine by pulling it slightly in a backwards direction, in such a way that
the rear end of the leg's plane surface makes contact with the ground.
5.4 STOPPING THE MACHINE
5.4.1. To stop work rapidly shift the accelerator lever from position ¼ to 0, the inverse of the
movement for starting the machine.
5.4.2. Before stopping the engine, leave it ticking over for two to three minutes and then press
the stop button until the engine stops completely.
5.4.3. Close the fuel tap by putting the lever in a horizontal position.

5.5 MAINTENANCE SERVICE AND STORAGE
5.5.1. Before undertaking any maintenance service on the compacting rammer, STOP THE
ENGINE COMPLETELY.
5.5.2. Daily maintenance service:
Remove all dirt, dust or oil entirely from the machine. Check the air filter, cleaning it as necessary.
Tighten up any areas where oil has leaked, and make sure that all other areas are tightened as
necessary.
5.5.3. Weekly maintenance service (every 50 hours):
Remove the cap of the air filter and clean the internal element using a neutral cleansing solution.
After drying, apply a fuel composed of a mixture of petrol and oil (if possible, utilize the fuel in use),
and shake well. Then, gently squeeze the primary external element (sponge) and place it on the
secondary internal element to cover it.
In the sparking plug, adjust the distance between electrodes to a value of between 0.7 and 0.8 mm.
Remove the oil cap (situated above the oil-level visor), and put the machine in a horizontal position
in such a way that the oil hole serves to drain off the used oil, placing the machine with the hole
downwards in order to drain the oil completely.
Place the machine upright again, and use the same hole to pour in new oil, until the correct level can
be seen in the visor.
The first change of oil should be made after 50 hours in operation, from the second time onwards
every 300 hours in operation.
5.5.4. Monthly maintenance service (every 300 hours):
Clean the inside of the fuel tank. Carefully clean every part of the machine, and again make sure all
the bolts and nuts are tightened up as necessary.
5.5.5. Correct storage:
For a prolonged period of storage after a particular job has been terminated, completely drain the
fuel from the interior of the tank, the fuel tube and the carburettor.
Remove the sparking plug, pour a few drops of oil into the cylinder, and by hand get the engine to
make a few revolutions in such a way that the oil reaches the whole area. As for the exterior, clean it
with a cloth dampened with oil.
To store the machine, keep it under cover in a location free from humidity and dust and out of direct
sunlight.
