ASSEMBLY

WARNING! Assembly of these types of ladders can be inherently dangerous. Please take all necessary precautions during the assembly process. Always use a separate ladder to finish assembly in high places. Never climb a ladder that is not completely assembled. Do not assemble or use a ladder with missing or damaged parts. Use proper lifting mechanics when assembling a ladder. Watch for overhead electrical hazards and obstructions.

STEP 1: FRAME ASSEMBLY
NOTE: DO NOT tighten bolts until instructed to.
NOTE : Back panel (F) has both round and slotted holes. The round holes are at the bottom, and the slotted holes are at the top (L1).

Place the ladder stile (D) on the floor. Be sure to assemble on a protective surface so the finish does not get damaged. (See Figure 1)
Using (6) 3/8-16 x 1¼” hex head cap screws and self-locking nuts, bolt the top (slotted holes) of the back panel (F) to the insides of L1. (See Figure 1)
Bolt the bottom (round holes) of the back panel (F) and back of the base panel (E) on the insides of L2. (See Figure 1)
Bolt the front of the base panel (E) to the insides of L3. (See Figure 1)

STEP 2: HORIZONTAL AND VERTICAL BRACE ASSEMBLY
NOTE : DO NOT tighten bolts until instructed to.

Using (3) 3/8-16 x 1¼” hex head cap screws, locate horizontal brace (G) on the outside of L4 and L5.
Locate the vertical brace (H) on the outside of L4 and L6.
Start self-locking nut onto screws at L5 and L6.
Repeat for another side.

WARNING! Never climb a ladder that is not completely assembled.

STEP 3: INSTALL SIDE HANDRAILS

** NOTE: DO NOT tighten bolts until instructed to.**

With a ladder on its side, install handrail (A) into the rear stairway tubes. Use the rubber mallet as needed for mating parts. (See Figure 2, Step 1)
Detach handrail brackets that are shipped attached to handrails.
Clamp side handrails to the outside of stairway tubes using handrail brackets and 3/8-16 x 2″ hex head cap screws, gray bushings and self-locking nuts. (See Figure 2, Step 2)
Repeat step 3 with the side handrail (B).

STEP 4: INSTALL REAR HANDRAIL BAR

Detach the rear handrail bar (C) that is taped to the handrail.
Insert notched bushing into each end of rear handrail bars (C). (See Figure 2, Step 3)
Position rear handrail bar between holes on the top part of side handrails using (4) 1/4-20 x 2¾” hex head cap screws. (See Figure 2, Step 3)
NOTE: You may now tighten all handrail bolts.

STEP 5: LEVEL LADDER

Stand ladder upright on a level surface.
Activate safe lock by stepping on the trip bar located in front of the first step.
This sets the ladder on the feet to level.
When steps are level, tighten all installed bolts.
NOTE: Do not proceed until the ladder is stable.
