WARNINGS
Rated Load: 1,000 lbs. Never exceed the Rated Load.
Professional installation by an EZ-ACCESS approved technician is required.
Prior to use, read and understand this manual and all other applicable manuals, including supplements and addendums,
if any, and warning labels, in their entirety. Learn and understand the location and function of all features, safety
devices, and labels before use. If you do not understand which manuals apply, or their content, do not use the system
and call 1-800-258-8503 for further information.
Do not remove safety labels. Maintaining all labels and manuals in legible condition is required by the system’s owner
and is essential for safe operation. If labels are missing, damaged, or become illegible, they must be replaced. A missing
or illegible label will fail to alert individuals of a procedure or hazardous operating conditions. For replacement copies,
please call 1-800-258-8503.
Do not use the system without properly installed handrails.
Metal conducts electricity. Never use near electrical current.
Use caution at all times. Do not run or jump on the system. Do not play on or around the system, including climbing on,
through, or under the handrails.
Do not use any part of the system, including handrails, to support planters, power cords, decorations, etc.
Never place anything under or attach anything to the system to gain height or to adjust for uneven surfaces.
Do not use any component not supplied or approved by the manufacturer with the system.
Before each use, check for damage and confirm that all components, hardware, fasteners, and locking mechanisms are
in place, in good condition, and are securely fastened. If any part of the system, including the canopy if present, is
damaged, loose, or missing, contact manufacturer and do not use until repairs can be made by an EZ-ACCESS approved
technician.
Before each use, confirm that the system is positioned securely. Check for ground shifts and adjust level if required.
Proper maintenance and upkeep of the system is vital to the health and safety of people using the system.
Keep the system clear of dirt, leaves, and other debris that may accumulate on the surface. Do not use if the surface is
covered with ice and or snow. Accumulation must be shoveled and the tread surface swept clean, prior to use.
Keep canopy (if present) clear of ice, snow, dirt, leaves and other debris at all times.
Always properly support and restrain the system in transit and or storage.
Always use system as described in this manual. Do not misuse or abuse.
If lag bolts cannot be installed, secure the platform to the building or structure in another structurally sound manner.

1. INSTALLATION
1.1. Set platform on its side.
1.2. Loosen platform leg adjustment bolts in each platform corner pocket, but do not remove. Adjust legs to desired
height and securely retighten platform leg adjustment bolts and washers (FIG. 2).
If using oversized feet, see ‘OVERSIZED FEET INSTALLATION (OPTIONAL EQUIPMENT)’ section.
1.3. Set platform in upright position.
1.4. Readjust the height of each platform leg as necessary to level the platform. A slight tilt away from structure of no
more than 1:50 will aid in drainage.
1.5. Remove the OSHA Riser Safety Pins and attach riser (FIG. 1E) to platform by placing the “T” in the riser’s upper
corner pockets into corresponding riser hanger (channels with roll pin) on the platform (FIG. 3).
1.5.1. The “T” placement determines height; use either upper or lower riser hangers as required.
1.6. Secure riser to platform by reinserting OSHA Riser Safety Pins into the riser hanger (FIG. 3).
OSHA Riser Safety Pins (FIG. 1D) must always be installed in the riser hangers on the platform corner pockets
before use (FIG. 3).
1.7. Loosen riser leg adjustment bolts in the lower riser corner pockets, but do not remove. Adjust legs to desired height
and tighten riser leg adjustment bolts securely (FIG. 2).
1.8. Insert the 60” (longer) side of platform handrail into platform corner pocket, on the side opposite the building or
structure.
1.9. Unfold the 40” (shorter) side of the platform handrail (FIG. 1H) and orient on the side opposite the riser, then lower
handrail into platform corner pockets until the snap button engages in the corresponding hole (FIG. 2).
1.10. Install riser handrail (FIG. 1J) into riser on the side opposite the building or structure.
1.11. Lag bolt (not included) the platform to the building using holes in platform angle braces (FIG. 2).
If lag bolts cannot be installed, secure platform to building or structure in another structurally sound manner.
1.12. Ensure system is set up in desired configuration, is correctly positioned, and complies with applicable OSHA codes.
1.13. Ensure all fasteners and locking mechanisms are in place and secured.

toward the leg adjustment bolt & washer and the square nut inside the leg (FIG. 4).
The two short legs install in the bottom of the riser and the four long legs install in the platform.
2.3 Install an oversized foot onto each leg with the foot oriented under the platform or riser (FIG. 4).
2.3.1 Adjust to the desired height, and then tighten both the thumb screws in the feet and the leg adjustment
bolts in the corner pockets securely.
