ASSEMBLY INSTRUCTIONS
Improper or incomplete assembly might result in a ladder that is unsafe to use.
•
Visually inspect all ladder components
prior to assembly
. Look at each part of the ladder immediately after you
receive the package from the shipper. Determine whether damage occurred during shipping. DO NOT assemble or use
the ladder stand if you notice any damage, especially to the step weldment, back leg weldment, base supports, or
handrails. Using a damaged component could lead to ladder collapse and result in serious personal injuries.
•
While assembling this ladder, confirm that only locking fasteners are provided, i.e. only locking nuts. Contact
(p. 1) if you find non-locking nuts. Only lock nuts should be used. However, lock nuts can only
safely be used once. Discard the used lock nut and install a new lock nut after unfastening a connection
•
DO NOT assemble the ladder by yourself. At least 2 people are needed for assembly.
•
Read the entire instruction manual before assembling this ladder.
•
DO NOT use the ladder if a wheel is damaged. Damaged wheels might cause the ladder to wobble or tip when used.
