Roller installation tips :
- Partly tighten the pin on the mast section and
insert the washer on the pin.
- Apply grease on the spacer so that it "sticks"
to the mast and does not fall to the bottom of
the profile.
- Press the spacer on the mast profile and slide
it. The roller, spacer and pin must be in line.
Grease
- Tighten the pin so that the roller slides on the
pin.
- Reposition the spacer in line with the pin.
Tighten the pin completely until the spacer is
fully inserted.
- When the spacer is correctly inserted, loosen
the pin by 1 turn to prevent the mast from
jamming during the alignment adjustment. Install
the locknut without tightening it (tightening of
the locknut after mast alignement adjustment).
! CAUTION
Mast profiles must be clean before replacing
the bronze spacers. Mast profiles must be
greased after the spacers h ave b een
replaced. The telescopic mast alignement
must be ajusted.
