Information
Before dismantling, get rid of any dirt by cleaning the chassis - engine assembly.When dismantling, keep together all parts originally paired together or paired due towear. Paired parts must be reused together or replaced together; they will have beenplaced in the order they were dismantled in, thus making refitting easier.Any parts which are changed must be replaced with original PEUGEOT parts. Checkthe state of the tightness seals, “ O ” rings and paper seals each time a dismantlingoperation is carried out.Lubricate all paired parts and bearings correctly when reassembling.

INTRODUCTION
This workshop manual concerns the FD1 engine which equips the Elyséo 125 cm³4-stroke model. It is intended to be used by dealers and their qualified mechanics.Bearing in mind that it is not possible to group together in one document all that amechanic needs to know, the person who uses this manual should have a basicknowledge of mechanical concepts and repair operations, in order to carry outinterventions under the best conditions of efficiency and safety.

MAINTENANCE OPERATION
SETTING UP
1. Preparation of the battery
Charging a dry battery:- Take out the battery.- Remove the six filling caps and the air vent plug.- Fill with electrolyte (35 % sulphuric acid =
1,28 g / cm³) up to the level marked “ UPPER LEVEL ”Reference ...................................... 752740 ................... 1 L...................................................... 752741 ................... 5 L- Leave the battery to settle for approximately half an hour.
Top up the level if necessary.- Charge the battery for at least 7 hours with a current of
1.2 A, using a regulated charger or for 2 hours maximum usinga non-regulated charger.
- Put the battery back in its place and connect the vapourevacuation pipe to it.
- Connect the red wire connector to and the green wireearth connector to .
- From then on, the battery level should be topped up ifnecessary using distilled water only.
2. Fuel
- Capacity ............................................................. 8.5 Litres- Lead free petrol 95 or 98.
3. Checking of levels
Relay box oil :- Put the vehicle on its stand on a level surface- Loosen and remove the filling screw and make sure that
the oil level comes up to the filling neck.Capacity ........................................................................ 0,12 L
- Tighten the screw to 12 Nm.
Engine housing oil :- Check the level via the eyehole on the right hand housing
(approximately 0.25 L difference between the top and bottomof the eyehole)
Coolant :- Check that the level is level with the top of the screw
thread in the expansion valve.Capacity .......................................................................... 1.5 L
4. Checks before handing over to thecustomer
- Pay special attention to the tightening of the wheel nutsfront .......................................................................... 65 Nmrear ......................................................................... 110 Nm- Check that the nuts and bolts are tightened correctly.- Check the adjustment and efficiency of the brakes.- Check the inflation pressure of the tyres when cold :front ......................................................................... 1,5 barrear .......................................................................... 1,8 bar- Check that the lights and signalling devices are working
properly (rear light, indicators, brake light, horn), and also thedifferent telltales.
- Carry out a road test.
