NOTE
Before removing the lower rollers, ensure the
upper rollers are installed.
Using ground controls :
1- Raise the telescopic mast to gain access to
the roller to be removed.
2- Unscrew the locknut from the roller to be
removed using a polygonal spanner.
3- Unscrew the roller pin to release the bronze
spacer and free the roller as indicated
previously.
Install the roller before removing another one
(§ 5.9.3.).
5.9.3. Rollers
The bronze spacer must be replaced if its
thickness is below 3,5 mm. Check the
condition of roller pin, bushings and roller
prior to installation. Replace damaged parts
with original parts. Grease bushings before
installation.
Roller installation tips :
- Partly tighten the pin on the mast section and
insert the washer on the pin.
- Apply grease to the spacer so that it "sticks"
to the mast and does not fall to the bottom of
the mast.
- Press the spacer onto the mast and slide it.
The roller and spacer must be in line with the
pin.

minimum thickness.
- Tighten the pin so that the roller slides onto the
pin.
- Reposition the spacer in line with the pin. Tighten
the pin fully until the bronze spacer is fully
inserted.
- Once the spacer is properly in place, unscrew
the pin by one turn to prevent the mast from
jamming during adjustment. Install the locknut
without tightening it (tightening of locknut after
adjustment of mast alignment).
Clean and grease the faces of the bronze
spacers on the mast. Refer to § 8.1 Lubrication
points.
After maintenance operation on the roller, the
