Multiple units installation with mast ties – pre-installation
(requires two twin mast adapters – sold separately)
Installation of mast sections and tie levels
11- Using an optional jib arm, a crane or a rough terrain forklift, load mast sections on
the motorized unit (see p. 119 of the Accessories section for more information on
the installation and use of a jib arm). There can be up to a maximum of four mast
sections on each side of the mast at a time.
A ninth mast section can be loaded on the link bridge of the motorized unit, as shown
in fi g. 1.32. It is recommended to install an optional deck extension on one of the fi rst
cantilevers attached to the unit to facilitate the handling of mast sections with the jib
arm. The deck extension must be installed on the side opposite to the jib arm, as
shown in fi g. 1.32. For information about the use and installation of an optional deck
extension, refer to p. 55 of the Bridges section.
Mast sections must be loaded equally on either side of the mast and taken alternately
from one side, then the other when installing to ensure good balance. Refer to the
Load Capacities section on p. 94 for more information about loading the platform.
10- If any of the limit switches is not working properly, the unit must be put out of service
until it has been inspected and repaired by a qualifi ed person. For the defi nition of a
qualifi ed person, refer to p. 7 of the Performance and Safety section. For more
information about limit switches and their corresponding alerts, refer to p. 77 of the
Control Panel section.
Verifi cation of limit switches and screen alerts (cont’d)
13- Once all required mast sections and tie levels are in place, install the mast head.

14- Make sure that the top limit trigger plate on the mast head is in a vertical position. If
necessary, loosen the thumb screws, fl ip the trigger vertically and tighten the thumb
screws by hand.
15- Test the operation of the top limit switch by raising the unit until the switch reaches the
trigger plate. The screen should display an alert for the top limit. If the limit switch is
not working properly, call the distributor/service center. For more information about limit
switches and their corresponding alerts, refer to p. 77 of the Control Panel section.
Installing and testing the top limit switch
Installing an optional deck extension will facilitate the handling of mast sections
with the jib arm.
12- Install mast sections until a fi rst tie level is required. For instructions on the installation
of a mast section, refer to p. 84 of the Mast and Mast Ties section. Refer to p. 86
of the Mast and Mast Ties section for instructions on how to install mast ties. For more
information about the schedule of installation of tie levels, refer to the Mast Tie Schedule
tables on p. 87 of the Mast and Mast Ties section.
Once the fi rst tie level has been installed, proceed with the installation of as many mast
sections and tie levels as is required by the layout plan and the confi guration. Any F2
Series motorized unit must not be used on a mast with a height over 500' (152 m).
If it is required to load 45' (13,7 m) of mast sections, a ninth mast section can be set
on the link bridge of the motorized unit.
