39. Other Operations in the Pits

39.1. Adding fluids (not fuel)

For Competitors who need to add fluids (not fuel) during the pit stop, the following procedure must be followed:

Once any tyre changes have been completed, and the mechanics in charge of the tyres have left the working zone, one mechanic with an yellow armband may proceed with adding any fluids (not fuel) to the car. For the avoidance of doubt, this may take place whilst refuelling remains ongoing.

39.2.

Other operations may be carried out on the car when any refuelling and/or tyre changes have finished and personnel undertaking refuelling and the mechanics undertaking the wheel changes and their equipment are no longer in the working area.

For case D (except during qualifying) and during the Bronze Test, free practice and pre-qualifying for cases A, B and C, these operations must be carried out in the pits/working area of the pit lane and parallel to the pit lane.

For cases A, B and C, during the race, only the following operations may be carried out in working area of the pit lane and parallel to the pit lane:

  • cleaning windscreens,

  • checking tyre pressures,

  • visual checks of tyres and brakes,

  • adding fluids (except fuel) (note that this may also take place during refuelling in accordance with Article 39.1 above)

  • downloading of data,

  • removal of dirt or grass from the radiator or repairs to the car without using tools,

  • For Case B only: brake operations subject to Article 39.3 below.

Any other operations must be carried out in the pit garage. The car must be pushed into the pit garage by not more than four mechanics. At the end of the operations, the car must be pushed out of the pit garage and restarted in accordance with Article 36.8.

At all other times, the following apply:

Personnel authorised in the pit lane working area after refuelling and tyre changes, for maintenance, repairs and driver changes:

  • 1 Car Controller.

  • A maximum of 4 mechanics carrying out maintenance operations, topping up liquids (other than fuel), making repairs or any other operation whatsoever (other than tyre changes).

  • A Data Technician may download data from the car by cable, card or data stick without performing any other task. The Data Technician does not require an armband.

  • The driver exiting the car may assist the driver replacing him.

  • Any other Team members standing in the working area (working lane, Article 34.4) will be considered as mechanics and working on the car, as will a driver if he performs any work on the car.

  • 1 'tyre' technician and 1 'brake' technician external to the Team may, without intervening or working on the car, proceed to conduct visual checks as well as with a temperature probe or pressure gauge. They will wear an armband in accordance with Article 12.4.

39.3.

Brake Operations during case B -- CrowdStrike 24 Hours of Spa.

During the tyre changes, the following procedure must be followed:

1: During the refuelling, the tyres must be removed from the car by the two tyre mechanics (green armbands). They must then take the wheels, tyres, and the tyre changing equipment (wheel guns) out of the working zone.

2: Once refuelling has finished and the refuelling personnel and their equipment have been removed from the working zone, four mechanics may then enter the working zone with the necessary tools to proceed with the brake operation.

3: Once these four mechanics have finished and left the working zone, the two tyre mechanics (green armbands) must put the tyres (either new or the previous used tyres) back on according to the standard procedures in Article 38.

4: Once the tyre mechanics (green armbands) have put the car back on its wheels and taken themselves and the equipment from the working zone, the other operations listed in Article 39 may take place.

During the brake operation, at no point must there be more than four mechanics in the working zone.

For the avoidance of doubt, this procedure must be followed in full, and cannot be altered depending on the number of discs changed or wheels to be removed.

39.4. Pit Stops after Damage during races

Should a car suffer damage during the race and repairs need to be carried out in the garage, the car may be pushed into the garage immediately after entering the pit lane. After the repairs have been completed, the car may be pushed out and placed parallel to the pit building. The Team may then proceed with a standard pit stop in accordance with Articles 37 and 38 above.
