Black Jack Folding Foot Installation The folding foot must be installed so that it is clear of any obstructions. The folding foot must be able to freely extend and retract to its full extension and full horizontal retraction. If the foot encounters an obstruction, for example a chassis rail or brake cables, before it is fully retracted to a horizontal position then there is a risk of serious internal mechanical damage to the Black Jack. The damage is caused by the leverage pressure (up to 3,500kg) the folding foot can add it if encounters an obstruction. This type of damage is NOT covered under warranty as it is a user installation error. When installing the folding foot, make sure the Black Jack orientation allows for full clearance of the folding foot. This may mean rotating the orientation of the Black Jack. If the folding foot cannot be installed so that it is clear of obstructions, then DO NOT USE IT. Install the silver adjustable foot instead.
