Ladder Operations)
Refer to Figure 66 and Figure 67
Ladder use is easiest and least obstructed when drill
wings are folded. Ladder may be lowered, used and
raised with wings unfolded, as shown at right, but lowest
ladder step may strike lowered openers, and will strike
raised openers. The lowest step is mounted with rubber
straps to prevent serious damage to openers.
1. Fold the wings for easiest ladder use.
2. Use one hand to hold the ladder up, while pulling
vertical pin
down.
3. Carefully swing ladder forward and down, until you
hear and see the horizontal pin
seat itself with the
ladder down. If an opener is in the way, it may be
necessary to push on the ladder to achieve lock.
Using Ladder
1. Pull outward on the ladder to check that the horizon-
tal pivot pin
is holding it.
2. Ascend and descend the ladder while facing the drill.
3. Use the handrails when on the higher steps.
