Verify Ladder Function

(see Parts Manual section: Walkboard and Ladder)

(see Operator Manual section: Operating Instructions -

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.
