WARNING
The jacks on the base extensions are designed to level the motorized unit and
must not be used to support the load nor the motorized unit.
WARNING
The mast head must be removed during installation. It is mandatory to put the
mast head back into place before resuming operation of the motorized unit.
A
Setup and Confi gurations
Standard single unit installation with mast ties – progressive installation
18- Once grease has been applied to the gears and the mast racks, install all mast guards.
Installation of mast guards
19- Adjust the outriggers and install planks, as required and allowed (see p. 111 of the
Accessories section for more information).
Installation of outriggers and planking
20- Make a fi nal verifi cation of the setup before authorizing workers to use the motorized
unit. Make sure that all the guardrails are in place and secure (see p. 108 of the
Accessories section for more information about guardrails). In all cases where workers
are exposed to fall hazards greater than specifi ed by local regulations, the installation
of guardrails or face guardrail supports is mandatory.
21- Before authorizing workers to use the motorized unit, perform every step in the daily
inspection checklist. It is recommended to fi ll out the handover sheet each time the
setup is modifi ed (addition of mast sections or tie levels, etc.). Refer to p. 134 of
the Transport, Storage and Maintenance section for more information about the daily
inspection checklist and to p. 136 for information about the handover sheet.
Verifi cation of the setup
Greasing of the racks and gears
17- Upon initial setup and subsequently after every 8 to 10 hours of cumulative runtime
(unit travel up and down the mast), grease must be applied to the gears and to the
racks from the top of the mast down. For more information, refer to the daily inspection
checklist for this motorized unit. Grease must be allowed to stand for 2-3 hours before
the motorized unit is used again. Use an open gear lubricant recommended by Hydro
Mobile. Refer to p. 133 of the Transport, Storage and Maintenance section for more
information on the appropriate lubrication method. Lower the motorized unit to base
level, verifying the mast ties and the mast bolts and applying grease, as required, on
the way down. Make sure that all bolt assemblies are tightened to the proper torque
and are in good condition, and that grease is applied appropriately.
14- Once the installation of mast sections is complete, install the mast head. The mast head
must be put back into place every time the installation of mast sections is complete.
Installation of the mast head
Installing and testing the top limit switch
15- 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.
16- 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.
Installation of mast sections and tie levels (cont’d)
13- Once the fi rst tie level has been installed, proceed with the installation of mast sections
and mast ties, as required. It is important to make sure that at least two tie levels
are in place.
