7 – Care and maintenance
To carry out the maintenance under good conditions, the following safety
rules must be met :
Block the wheels.
Engage the mechanical brake. (hand brake)
Unload the vehicle.
1- Check the brake system (every 6 months)
a- Parking and emergency brake
Verify the correct tension of the parking / emergency brake. The parking brake
lever should not be able to reach the last ¼ of the ratchet. If this is not the case,
tighten the cable.
Procedure for tensioning the cable :
Set the parking brake lever in the off position and ensure the
immobilisation of the vehicle by placing chocks in front and behind the wheels.
Loosen the cable clamps on one side,
Re-tension the cable
Re-tighten the cable clamps
Perform a test
If it appears that the brake rods (see fig.1 below) require too much
angle to allow for efficient braking, take up the play at the pads (see
the following: b)
b- Service brake
Check operation of the brake cylinders, make sure they are not at full-stroke and
control their mounts and the return springs (cylinders should not extend more
than two thirds of their maximum stroke or 100mm).
If this is not the case, proceed to remedy the brake linings.
To do this :
Set the parking brake lever in the off position and ensure the
immobilisation of the vehicle by placing chocks in front and behind the
wheels.
Remove the circlip at the end of the brake cam (see fig1 next page)
Disconnect the link rod of the cam.
Using a pipe wrench for example, exert a torque on the brake cam
simulating the braking.
Replace the link rod on the cam in this position.
Replace the circlip.
