INSTALLATION
3.1
OVERVIEW: Installing a davit system can be a lengthy procedure with multiple steps. Effective planning and awareness
of your worksite and your equipment are of great help in making this process move as smoothly as possible.
3.2
PLANNING: Plan your Fall Protection system before starting your work. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements and limitations specified in these instructions.
A. SHARP EDGES: Avoid working where system components may be in contact with, or scrape against, unprotected
sharp edges and abrasive surfaces. All sharp edges and abrasive surfaces should be covered with protective material.
B. COMPATIBILITY: When installing your davit system, it is important that you use compatible components. Each
product model is compatible for use with only a specific set of davit or davit base models. See below for a list of
compatible combinations.
A maximum of two Mast Extensions may be used when operating the Variable Davit System, as long as the combined
height of the Mast Extensions does not exceed 90.0 in. (228.6 cm).
When combined with the 8518001 Davit Arm, the Portable Base (8518005) may be used with either the 8518509 or
8518002 Mast Extension. The Portable Base may alternatively be used with the 8518382 Davit Arm without a Mast
Extension. See Figure 5.1 for reference.
The one-piece Davit Arms (8518382, 8518383, 8518384) are not allowed for use with any Mast Extensions (8518002,
8518003, 8518004, 8518509) covered by this instruction. See Figure 5.2 for reference. The one-piece Davit Arms
(8518382, 8518383, 8518384) may be used with 3M Davit Bases covered by other 3M instruction manuals. Refer to
the 3M Davit Base instructions for additional compatibility requirements.

INSTALLING THE VARIABLE DAVIT SYSTEM: The Variable Davit System is installed in order of the Davit Base, the
Davit Mast, and the Davit Arm. See Figure 6 for reference. To install the Variable Davit System:
INSTALLING THE DAVIT BASE: Figures 6.1 illustrates installation of the Davit Base. To install the Davit Base:
1.
To get started, place each component of the Variable Davit System on the ground before you, as seen in Figure 6.1.
The Davit Arm (B), Davit Mast (O), and Davit Base should be before you. The Davit Base should include its Center
Assembly and two Leg Assemblies.
2.
Remove the Locking Pin (D) from one of the Leg Assemblies. Rotate the Leg Tube (E) within the Leg Sleeve (F) from
transport position (G) to operating position (H). Reinsert the Locking Pin.
3.
Insert the Leg Assembly into the Center Assembly (I). Remove the Locking Pin (K) from the Center Assembly and
reinsert it through both the Center Assembly and the Leg Sleeve once the proper width adjustments (J) have been
made.
