Never perform service while the platform is elevated without first blocking the elevating assembly.
DO NOT stand in the elevating assembly area while deploying or storing the maintenance brace.
Refer to Figure 2-9 for the location of the Height Limit Switch.
1. Deploy the maintenance brace (see “Blocking the Elevating Assembly” on page 2-8).
2. Place a reference mark alongside the switch to establish its position.
3. Disconnect the electrical connector.
4. Remove the capscrew from the switch bracket, and remove the switch.
5. Install the new switch, align it with the reference mark and tighten the capscrew.
6. Connect the electrical connector.
7. Check the Height Limit Switch and adjust if necessary.

DJUSTMENT
Adjust the Height Limit Switch to stop elevation at 7,86 m (
25 ft. 10 in.
) A tape measure at least 8 m
(
26 ft.
) in length is required to adjust the Height Limit Switch.
1. Place the machine on a firm, level surface.
2. Use adhesive tape to attach the tab of a tape measure to the front edge of the platform (see
Figure 2-8). Ensure that the locking device on the tape measure is disengaged and extend the tape
measure to the surface.
3. Deploy the maintenance brace (see “Blocking the Elevating Assembly” on page 2-8).
4. Place a reference mark alongside the Height Limit Switch to establish its position.
5. Fully elevate the platform. The tape measure should un-roll as the platform elevates.
NOTE:
Do not return the maintenance brace to the stowed position at this time.
6. Measure the distance from the platform deck to the surface (see Figure 2-8).
• If the distance is correct, store the maintenance brace and fully lower the platform.
• If the distance is not correct, proceed to Step 7.
7. Lower the platform until the maintenance brace is properly set.
8. Loosen the capscrew and adjust as follows:
• If the distance is
more than
7,86 m (
25 ft. 10 in.
), rotate the switch slightly clockwise and tighten the
capscrew.
• If the distance is
less than
7,86 m (
25 ft. 10 in.
), rotate the switch slightly counter clockwise and
tighten the capscrew.
