•Using and handling fuel and oil
It is essential to stop the engine and set the control to the stop position before carrying out any work involving fuel (filling up, checking
the level, draining, etc.).
Always keep suitable extinguishers ready for use in all areas where fuel is handled (storage, filling up, etc.).
Always store fuel and oil in separate cans specially designed for the purpose and bearing the labels required by regulations. They must be stored in a
safe place, well away from all types of fire hazard.
Each time a machine is started up, and while it is running, make sure that there are no fuel leaks from any part of the machine. If a leak is suspected,
stop the engine immediately and do not restart the machine until the leak has been repaired.
Never carry out any work on a fuel tank or handle fuel to fill a tank, or for any other reason, in an area where there could be a fire hazard (such as a
burning cigarette, a blowtorch, sparks, etc.) or substances that are incandescent or at a high temperature (such as welding spatters, slag, clinker, etc.).
All such work must always be carried out outdoors or in a well-ventilated area.
Always turn all mobile phones off while filling a tank with fuel or handling fuel.
Carefully tighten the fuel filler cap each time, and check that no fuel leaks from it.
Always remove a filler cap slowly, to enable any internal pressure to be released without spraying any fuel out. Take special care if the surrounding
temperature is high.
When putting fuel in a machine that has heated up, never fill the tank completely. Do not put in more than three-quarters of the tank capacity.
If fuel starts to boil in the tank when putting fuel in a machine that has heated up, screw the cap on again immediately and leave the machine to cool
down.
Make sure the fuel used is suitable for the type of engine on the machine. See the user manual for the engine.
Do not inhale fuel vapour.
If it is necessary to drain the fuel tank, pour the fuel into a container designed for the purpose and bearing the labels required by regulations. Always
close them tightly, even if they only contain a small quantity. Never use a glass container.
Never use fuel for cleaning work. Use only non-flammable, non-toxic products that are harmless for the user, the equipment and environment.
If fuel has been spilt near the filling area for any reason, clean it up immediately. Clean straightaway any spillage of fuel on the skin. Make sure no
fuel has been spilt on your clothes; otherwise, change clothes immediately. Remove all rags or other materials used to wipe fuel, and store them in a
safe place well away from all sources of heat or combustion. Move the machine well clear of any spilt fuel before starting it up (at least 6 metres
away), and do not move any closer to the area while the engine is running.
IN CERTAIN CASES HANDLING OIL CAN GIVE RISE TO THE SAME TYPE OF RISKS AS HANDLING FUEL.IT IS THEN ESSENTIAL TO TAKE THE
SAME PRECAUTIONS WITH OIL AS THOSE SET OUT ABOVE FOR FUEL.

1.3 SECT_Gb_00007_120724.doc 1.3
•Tools to be used on the machine
Use only the types of tools intended for normal use of the machine.
Measure the speed of all rotating tools at regular intervals.
Never use tools at speeds greater than the maximum speed for which they have been designed and approved.
Never use damaged tools or tools that have reached their maximum level of wear.
•The engine on the machine
Never touch the hot parts of the engine, and especially the exhaust pipe. If it is necessary to work on the engine, wait until it has cooled down.
The factory setting of engine corresponds to the conditions of the production site (fuel, temperature, altitude, etc...), verify at receipt of the
machine the rotational speed of the engine and correct if necessary.
Check the engine rotation speed at regular intervals, and especially after fitting tools or reassembling the machine. Adjust if necessary.
Never exceed the speed shown in the technical specifications.
After starting with the choke, remember to return the choke to the normal running position.
Never wind the starter rope around your hand, and never release it suddenly.
If the machine does not operate correctly after the engine has been started, stop the engine and inform the head of maintenance.
For petrol engines, use only spark plugs whose tops are as shown in drawing 1 opposite. If the plug is fitted with a
screw top, make sure the top is fully tightened. After fitting the spark plug, make sure that the plug cap is in good
condition and that it stays firmly on the plug. Carefully check the fastening system to make sure that no sparks can
be formed.
•Using trolleys (If applicable)
A machine designed to work on a trolley must not be used without the trolley. The trolley is thus an integral part of the machine. The machine
and the trolley must not be used separately.
Trolleys whose use is dedicated to a machine must never be used to transport equipment or personnel, or attached to a vehicle.
Before fitting the machine on its trolley, it must be placed correctly on the track to ensure that it can run freely. If it is on a sloping section of
track, make sure the trolley is kept immobile while the machine is being put on the track or taken off it.
Attention, the trolley takes up the full width of the track and can cause injuries to the legs if it hits someone.

FRANCE
Lightweight portable vibrator VPS
The VPS lightweight portable vibrator has been designed for continuous ballast-tamping by vibration under all types of sleeper (wood, concrete, steel). It
meets ad hoc requirements and is characterized by being rapid and easy to put into use and its self-contained power unit.
Easy-to-handle, self-contained and efficient, the lightweight portable vibrator is the ideal compromise between performance and flexibility.
Its power and lightweight make it extremely easy to use with its incorporated drive unit that enables work to be done at any angle and significantly increases
production performance.
Considerable research work has been carried out on vibration characteristics in order to reduce the level of vibrations transmitted to the operator and protect
the petrol engine whilst maintaining excellent tamping quality at the same time. Fitted with a suitable tip, the vibrator provides operators with a highly
efficient machine, irrespective of depth of ballast and lifting height.
The machine is fitted with its own petrol engine and, as such is completely self-contained and can be easily used by a single operator.
The weight of the lightweight portable vibrator has been reduced as much as possible to make it easy to transport, but capable of sinking into ballast by its
own weight without needing to be pushed by the operator. The machine’s ergonomic design gives the operator maximum visibility and optimal handling
conditions.
Contrary to methods used by other vibrators, the action given by the GEISMAR self-contained vibrator is neither percussion-based nor unidirectional. The
strong vibration movements produced by the engine are transmitted to the ballast via the tip and body assembly.

Inspection of protective housings and mouldings (this check must be made with the engine switched off)
Check visually that there are no external defects, distortions, superficial cracks, wear or marks of corrosion.
Level-checking (these checks must be made with the engine switched off)
-Fuel level: Check the fuel level and top-up if necessary ( : Refer to §1.3 “General safety regulations” / sub-§: “Using and handling fuel” before any
operation”).
-Engine oil level: Check the engine oil level and top up if necessary. (See the documentation on servicing the engine supplied with the machine).
Checking operation (these checks must be carried out with the engine switched off)
-Check that the accelerator trigger and the ON/Off switch work correctly. These units must move without difficulty and never undergo any
modifications.
-Visually check the condition of the fixed stops, the silent blocks on the handles and the machine as well as the state of the bellows and protective sleeve.
Check on safety devices:
-Check that handles are clean and dry.
-Start up the engine ( : Refer to §4.2 “Starting up the lightweight portable vibrator”) and check that it stops correctly when the switch is moved to the
“0” position.
SHOULD ANY ANOMALY BE DETECTED DURING THE INSPECTION PHASE OR WHEN IN OPERATION,THE MACHINE MUST BE RETURNED
TO A COMPLIANT CONDITION BY QUALIFIED PERSONNEL OR THE MANUFACTURER,BEFORE REUSE.

4.2 Starting up the lightweight portable vibrator
Systematically check the condition of the tip before using the lightweight portable vibrator. There must be no cracks on the vibrator’s tip and barrel. Should
any anomaly be observed, change the faulty parts (See §5.1.10 “Replacing the tip on the lightweight portable vibrator”). Systematically check the oil level on
the engine before start-up. Never use the machine without its exhaust deflector.
Positions for choke lever, Item ①(See Fig.1)
=Normal running position – the engine is running or ready for start-up.
To move the choke, Item ①from position to , push it to the required position.
= Cold start – position for starting the engine when cold.
Positions for control handle, Item ②(See Fig.2)
0 = Motor stop – ignition switched off.
1 = Running position – position for starting the engine when hot.
Start = Start-up position – position for starting the engine when cold.
To start the engine:
➊ Push switch Item ②to its “Start” position if the engine is cold. To do this, move the switch from position “1” to the
“Start” position whilst pressing the accelerator trigger at the same time. Or move the switch to position “1” if the engine
is hot.
➋ Position the choke lever, Item ①(See Fig.1 and Fig.3) depending on the outside and engine temperatures:
-If the engine is cold, place the choke lever on (cold start).
-If the engine is hot, place the choke lever Item ①on (hot start), idem if the engine has already run,
but is still cold or if the engine is very hot and has been stopped for less than 5 min.
➌ Place the tip on the ground, and hold the lightweight portable vibrator in a vertical position. Then start the
engine by pulling on the starter rope Item ③vertically.
During the start-up phase, make sure that the tip is not close to any obstacle, especially sleepers or
rails.
Do not start the machine holding it with the acceleration trigger. In this position, the operator
may lose control of the lightweight portable vibrator due to a lack of stability.
➍ After the first pull, put the choke lever Item ①back to (See Fig.1) and switch Item ②to position “1”.
Continue pulling vertically on the starter rope Item ③until the engine starts. As soon as the engine starts
running, let it run at idling speed for 30 seconds before use. If, when accelerating:
-The engine does not run smoothly, the vibrator is not hot enough.
-The engine runs smoothly, the vibrator is hot enough to begin work.

4.3 Instructions for using the lightweight portable vibrator
Before starting the lightweight portable vibrator, be sure to hold it in a vertical position with the tip on the
ground. Do not start the lightweight portable vibrator with the tip in the ballast.
When in a work position with the tip positioned as shown in Fig. 1, it must be moved under the sleeper. This
movement is carried out by the operator. To obtain good results, the tip must always be placed close to the rail.
The tip moves under the rail and compacts the ballast where maximum density is required.
The lightweight portable vibrator must always be used with the engine running at full power.
We recommend that the following instructions are followed for obtaining the best results:
•Fig.2 The vibrator body is placed in a virtually vertical position against the sleeper, which allows the tip to penetrate the ballast without removing
any ballast from it.
•Fig.3 Then the vibrator must be angled downwards so that the tip passes under the sleeper. Vibration will make a sufficiently large opening under
the sleeper, for an extra quantity of ballast to be fed in.
•Fig.4 The ballast is then pushed under the sleeper by moving the vibrator to and fro at which time the ballast is completely tamped down. Do not try
to force or push the vibrator. Its weight is quite sufficient by itself. Any extra manoeuvres will delay its action. The engine must always be allowed to
vibrate freely. The tool just needs to be guided. Penetration into ballast that is in poor condition is made easier by pointing the tip downwards. The tip must
be inserted close to the sleeper and along its side.
•Fig.5 Carry out a left-right-left movement using the grips on the lightweight portable vibrator to accentuate the ballast-tamping operation.
The lightweight portable vibrator is fitted with a chassis mounted on shock-absorbers so that vibration is reduced to a minimum for the operator. This reduces
operator fatigue and enables operators to increase the length of working periods with the lightweight portable vibrator.
Always use the lightweight portable vibrator at full power when ballast-tamping. Do not jog the accelerator trigger. Never use the
lightweight portable vibrator for more than a few seconds with the tip outside the ballast as this may damage the machine.

4.5 Storage
4.5.1 General storage instructions
During periods when the equipment is not being used, it is essential that it be stored correctly to keep it in good condition. Poorly stored equipment is liable to
show risks of deterioration when reused. Therefore, it is important for the personnel in charge of storage to use the utmost care in storing this equipment away
and to comply scrupulously with recommendations.
Protection systems for storing
The choice of protection systems for storing depends on 2 main factors:
-The length of storage time.
-Storage conditions: “Non-sheltered” storage (exposed to weather conditions) and “sheltered” storage (a building, a closed or open shed, a canopy, etc.).
The equipment may only be stored away after it has been “run in”. Measures must be taken for providing easy access to the equipment for carrying out
servicing operations.
Storage premises
Generally speaking, equipment storage premises must offer the best possible protection against:
-dust, exhaust gasses and moisture.
-direct sunlight.
-rapid changes in temperature.
Putting into store
The condition of equipment when it is re-used after storage depends on the way it has been prepared and protected before being stored away.
-Equipment must be cleaned (after cleaning, protect mobile elements with grease).
-A technical inspection must be made for detecting any possible anomalies.
4.5.2 Special storage instructions
In the event of non-use for over a week:
Using a well-ventilated area, empty the fuel tank into a recipient and clean the tank.
Eliminate fuel in compliance with environment protection regulations.
Run the engine until the carburettor is completely empty, otherwise the membranes in the carburettor may stick.
Clean the machine thoroughly, especially the fins on the cylinder and the air filter.
