4.2.2 – Use on a grooved rail
(if the machine if equipped with grooved rollers)
Roll the machine on the rail using its two flat rollers. The guide
flanges, centred in the groove, hold it in place laterally (Refer to 3.3
Adjusting the guide rollers).

to raise and lower the wheel.
■
Start by trimming the part to be ground up to roughly 1mm of rail
surface. To do this, work in a series of quick runs, driving the
machine in short movements back and forth along the rail. On
each run, turn by a fraction of a turn the flywheel Item

■
To finish, return to the rail top grinding position. Then adjust the
wheel precisely with respect to the rail profile. To do this, skim the
wheel along the rail (some sparks will appear). You do not need to
perform this operation in zones close to the weld but rather in
zones where rail profile is correct.
■
Grind the entire profile until all weld traces have vanished. Finish
by spreading the fillet over roughly 10 cm on either side of the
weld. Check flatness using a perfectly rectilinear rule. If necessary,
compensate wheel wear using the flywheel

an indentation be formed if these instructions are complied with.
Once grinding is complete, rotate by 3 or 4 turns in an anti-clockwise direction

. The wheel is protected in its casing and
there is no risk of it coming into contact with the next weld.
