Scaffold Setup - Cosco II Instrucciones De Operación Y Seguridad

K. Scaffold setup:
➍
1. To configure as a scaffold, with ladder flat on
the ground, unlock the two Rail Lock Pins
on the top Outer Ladder Unit (See step
D1 of D. Rail Lock operation, Pg. 5)
and slide Outer Ladder Unit
completely off. Flip ladder over
and repeat for other Outer Ladder
Unit. Note: Be aware of sliding/moving
parts. Keep hands and feet clear.
2. Open Inner Ladder Unit (See steps C1 and C2 of
C. Hinge Lock operation, Pg. 4) and place upright
(Fig. K2).

3. Using separated Outer Ladder Units,
place one unit flat on floor with rungs facing up. (Fig. K3)
4. Place second Outer Ladder Unit (with rungs facing up) on top of first
Outer Ladder Unit. Pivot Rail Lock Pins on bottom Outer Ladder Unit into
ports on top Outer Ladder Unit. (Fig. K4)

5. Set upright. Pull two Outer Ladder Units away from each other until the
sections are fully spread into the A-frame position. Connection is correctly
made when second Outer Ladder Unit is slightly lower and seated against
the plastic rung bracket of the first Outer Ladder Unit as shown in Fig. K5.
Incorrect alignment will prevent fully spreading ladder units and may result
in ladder damage (See Fig. K6).

6. Position two parts of scaffold side by side. Place a scaffold-grade plank*
no longer than 10 feet long (3.05 m) across all four rungs at desired height
leaving at least 2 inches (5.08 cm) extending beyond outer rung on each
end (See Fig. K7). Refer to chart below for maximum plank height for your
ladder model. Use only scaffold-grade plank that is rated strong enough to
support you and your equipment. Do not use split, broken or partial-cut
wood as plank. Too much plank
deflection or bowing may result in
serious injury.
*Scaffold-grade plank not included.

Position plank on ladder sections to avoid slippage or movement.
