• To prevent hazardous situations from occurring, immediately adjust the spring tension as described in the following section.
Spring pull adjustment:
• With the system released, manually guide the boom to approximately half of its stroke (45°) (FIG. 11A) and leave it. If the boom
tends to fall, use the spring adjuster, turning it clockwise; if instead, the boom tends to rise, use the spring adjuster and turn it anti-
clockwise, see FIG. 11B. The correct balance is when the rod is at 45° and is stationary.
• Once the correct balance of the boom has been found, lock the system using the locknut in the spring mechanism (FIG 11B).
