Figure 22, Horizontal Leveling with Bubble Level

There are two leveling procedures, one for mounting the foot on a vertical surface and

the other for a horizontal surface. Leveling procedures for special mounting systems

are provided in the specific mounting instructions given later in this manual.

The following leveling procedures gives a basic understanding of how to level the

mast for each mounting system. Abbreviated leveling instructions are also given later

in this manual in the instructions for different mounting surfaces.

Vertical Mounting System

With mounting the foot on a vertical surface, the mast is leveled horizontally (side to

side) and vertically (up and down). Use either a bubble level or plumb line with the

following procedures to level the mast.

Use the following procedure to level the mast with a bubble level.

1. Place the level on the mast as shown in figure 22. Move the bottom of the

mounting foot to center the bubble in the window of the level.

2. With apencil, draw line from the center line of tbe lower f6ot onto the waU.

This line is a reference mark that enables the foot to be restored to level

without using the level again. Before drilling the remaining holes required

to install the foot, ensure this line aligns with the center line of the

mounting foot.
