USE
4.1
bEFOrE EACH USE: Verify that the work area and Personal Fall Arrest System (PFAS) meet all criteria defined in Section
2 and that a formal Rescue Plan is in place. Inspect the Variable Davit System per the 'User' inspection points defined
on the "Inspection and Maintenance Log" (Table 2). If inspection reveals an unsafe or defective condition, do not use the
system. Remove the system from service, clearly mark the system "DO NOT USE", and destroy it or contact 3M regarding
replacement.
4.2
ADJUST FOr SySTEm OFFSET: To avoid tipping the base during use, the Variable Davit System must be adjusted to
account for offset. See Figures 9 and 10 for reference. To adjust for offset requirements:
Determine the operating offset of the Davit mast: See Figure 9 for reference. Pin Positions (PP) are listed 1 - 4.
The Pin Positions regulate the Top Pulley (A4) and Bottom Pulley (A3) offsets. The first table within Figure 9 displays the
maximum offset (Max) and minimum offset (Min) for each pulley in all four Pin Positions. Maximum offset is determined
when the Adjustable Gusset is fully collapsed, with no visible threads. Minimum offset is determined when the Adjustable
Gusset is fully extended. Once the Pin Position is set, the second table within Figure 9 should be consulted for the
maximum load of each attachment point.
;
For use of the A1 attachment point, the distance of attachment from the Mast (Y) must be no greater than 15.0 in.
(38.0 cm).
Adjust the Davit base for the Davit mast: See Figure 10 for reference. Once the operating offset of the Davit Mast has
been determined, the Davit Base should be adjusted to match its requirements. The Base Pin Position (BPP) of each Leg
Assembly should be matched with the Pin Position of the Davit Mast. For example, a Pin Position of 4 on the Davit Mast
should be matched with a Base Pin Position of 4 on the Davit Base.
;
After the Davit Base has been adjusted, verify that the Davit Base is level again with use of the Level Indicator. If
necessary, make height adjustments of the Adjustable Feet.

INSPECTION
5.1
INSPECTION FrEQUENCy: The Variable Davit System must be inspected at the intervals defined in Section 1.
Inspection procedures are described in the 'Inspection and Maintenance Log' in Table 2. Inspect all other components of
the Fall Protection or Rescue System per the frequencies and procedures defined in the manufacturer's instructions.
;
In addition to the annual inspection and inspection before each use, the Variable Davit System should be inspected
at least once each week.
5.2
DEFECTS: If inspection reveals an unsafe or defective condition, remove the Variable Davit System from service
immediately, clearly mark the system "DO NOT USE", and destroy it or contact 3M regarding replacement. Do not attempt
to repair the Fall Arrest System.
5.3
PrODUCT LIFE: The functional life of the Variable Davit System is determined by work conditions and maintenance. As
long as the product passes inspection criteria, it may remain in service.
6.0
MAINTENANCE, SERVICING, STORAGE
6.1
CLEANING: Periodically clean the metal components of the Variable Davit System with a soft brush, warm water, and a
mild soap solution. Ensure parts are thoroughly rinsed with clean water.
6.2
SErVICE: Only 3M or parties authorized in writing by 3M may make repairs to this equipment. If the
Variable Davit System has been subject to fall force or if inspection reveals an unsafe or defective condition, remove
the system from service immediately, clearly mark the system "DO NOT USE", and destroy it or contact 3M regarding
replacement.
;
Only 3M or parties authorized in writing by 3M may make repairs to this equipment.
6.3
STOrAGE AND TrANSPOrT: When not in use, store and transport the Variable Davit System and associated fall
protection equipment in a cool, dry, clean environment out of direct sunlight. Avoid areas where chemical vapors may
exist. Thoroughly inspect components after extended storage.
