Removal and Installation

REMOVE PULLEY SUPPORTS AND/OR PULLEY ONE BY ONE.
ALWAYS REPLACE AND SECURE A PULLEY SUPPORT AND/OR
A PULLEY BEFORE REMOVING ANOTHER ONE. THE SAME SUIT-
ABLE BLOCKINGS USED FOR CHAINS REMOVAL SHOULD BE
USED TO SUPPORT MAST SECTION DURING DISASSEMBLY.
NOTE: Unless the pulley supports need replacing, there is
no need to remove the lifting chains for removing the
pulleys. If the pulley supports need replacing, follow
the lifting chain removal and installation procedure.
Once the chains slackened, only remove the long
anchor to be able to run the chain out of the pulley
support (if necessary).
Rotate the turntable to the left to get an easier access to
the mast assembly and to be able to install supports for
the mast sections.
Pulley Removal
1. Follow the lifting chains removal and installation pro-
cedure to install blockings under the appropriate
mast section(s).
2. Remove the locknut from a long anchor and loosen
