Remove and install base covers
To perform any maintenance on the electrical panel or HPS it is necessary to remove one or more of the
base covers. The only equipment required is a 4 mm hex key (supplied).
To remove the front cover:
1. Be sure all cables are disconnected from the 59 Series control unit on the right side of the base.
2. Loosen the four M6 button head cap screws (1, Figure 10) on the side of the base unit, at the front.
It is not necessary to remove the cap screws, just loosen them.
3. Remove the two M6 flat head cap screws on the top of the base unit, at the front. One screw is shown
as (2) in Figure 10, the other is hidden behind the hydraulic control panel.
4. Pull the front cover forward to remove it.
To install the covers, perform the above procedures in reverse. Tighten all cap screws until fully seated
plus one-quarter turn.
To remove one or both side covers:
1. Remove the six M6 button head cap screws (3, Figure 10) on the rear panel of the base unit, three
on each side. It is not necessary to remove the rear cover; it is still held in place by flat head cap
screws through the top plate.
2. Loosen the four M6 button head cap screws (1, Figure 10) on the side of the base unit, at the front.
It is not necessary to remove the cap screws, just loosen them.
