understand the following instructions before using the system.
• Only trained personnel should use this system and its components.
• Do not use if the unit or any part of the system appears to be damaged.
• Do not use the system if any components do not operate properly.
• Use in highly corrosive or caustic environments dictates a more frequent
inspection and servicing program to ensure the integrity of the system is
maintained.
• Do not attempt to repair this system.
• Personal fall arrest systems and components subjected to impact loading shall be
immediately removed from service and shall not be used again for employee
protection until inspected and determined by a competent person to be
undamaged and suitable for reuse.
• Employer must provide for prompt rescue in the event of a fall.
• All equipment must be inspected before each use.
• Any component exhibiting deformities, unusual wear, or deterioration must be
immediately discarded.
• This product is designed for personal fall protection. Never use fall protection

B. LIMITATIONS
The Miller® Edge™ is intended for use on horizontal surfaces or surfaces with < 5% grade. The following
limitations must be read, understood and followed before installation can take place.
• FLOOR STRUCTURE: The structure to which the unit is used must be no less than 5/8”
(15.9mm) thick plywood and capable of supporting the weight of the system and the
loads applied by the system in event of a fall. The surface must be even and no greater
than a 5% grade from horizontal.
• SYSTEM CAPACITY: The maximum number of user’s per unit is 2 (two). Only (1) user
per individual anchor point is permitted. The capacities are based on maximum user’s
weight, including tools, clothing etc. of 310 lbs. (140.6 kg) each or 620 lbs.
(281.2 kg) total weight. Warning: Maximum capacity for each attachment point is 310
lbs. (140.6 kg). Do not exceed this weight per individual attachment point.
• COMPONENT COMPATIBILITY: The Miller® Edge™ is designed for use with Miller
retractables and approved components only. Substitution or replacement with nonapproved components will endanger the compatibility within the system and may affect
the reliability and safety of the total system. It is recommended the user(s) attaching to
this device must only use Miller retractable lifelines and approved compatible connectors.
• LIFTING RINGS: The lifting rings are to be used solely for lifting the unit up by crane or
other means of a lifting or hoisting type structure to locate the unit on to the working
surface. Do not use the lifting rings for fall protection.
• MOVING THE SYSTEM: Always disconnect before attempting to move the unit. Move
the unit by using the horizontal handle at the rear of the unit using a pushing type motion.
Steering the unit can be accomplished by using the handle located on the vertical boom.
(Ref. fig.1) Never expose a worker(s) to a fall hazard by pulling the unit from the handles
located on the vertical boom or from the anchorage points while connected to the unit.
• INSTALLATION DISTANCE: Minimum installation distance from the front of the unit to
the leading edge is 2 ft. Minimum installation distance from the side of the unit to the side
leading edge is 3 ft. (Ref. fig. 10)
• CONNECTORS: Connectors used within the system must be able to support a minimum
of 5,000 lbs. Non-approved, non-compatible components may cause accidental
disengagement (roll-out). Only self-locking, self-closing connectors are recommended by
Dalloz Fall Protection.
• SURFACE GRADE: The Miller

• WORKING DISTANCE: The maximum working distance forward, measuring from the
vertical boom is 26 ft. The maximum working distance from the side of the unit,
measuring from the vertical boom is 12 ft. Ref. figure 10. WARNING: DO NOT EXCEED
WORKING DISTANCE REQUIREMENTS.
• ANCHORAGE HEIGHT: To determine the anchorage height of the unit measure from the
eyebolt to the surface the unit is supported with. Ref. fig. 9.
