This completed form must be sent to RTL for the product to be covered under warranty.

The TMA Support
Structure Rotates to
Lifted Position Before
the TMA will Lift to the
Vertical Stored Position
The TMA is Designed to
Remain in the
Horizontal Position Until
the Support Structure in
the Lifted Position
Support Structure in
Final Lifted Position and
TMA is Shown in the
Final Vertical Position
Rotation of the TMA and Support Structure is Hydraulically
Sequenced and is Activated when the Up or Down Button is Pressed
The TMA Hydraulic System Sequences the Movement of the TMA,
Latch, and the Support Structure

The TMA Must be Fully
Deployed into the Horizontal
Position Before the Support
Structure Begins to Rotate to
the Horizontal Position
Rotation of the TMA and Support Structure are Hydraulically
Sequenced and is activated when the Up or Down Button is Pressed

The Gold Latch Secures the TMA in the Stored Position
Minimizing TMA Movement. The Latch Design is Based
on a Car Hood Latch. When the TMA is Rotated into the
Stored Position the Latch Engages the TMA Frame*.
When the TMA is Deployed the Latch Disengages the
Frame by means of a Sequenced Hydraulic Cylinder that
Disengages the Latch Thereby Allowing the TMA to
Rotate to the Horizontal Stored Position.

Step 1. Removing the Strut From its Pallet
Attach a suitable set of lifting rings/straps to the upper steel diaphragm of the Strut assembly. All rigging should have a minimum lifting capacity of 4,000 lbs (1,800 kg) and be in good
condition. Each lifting strap assembly should be the same length. Attach one lifting strap to each angle of the diaphragm. Position a forklift (minimum capacity of 2,500 lbs, [1,150 kg]) with
the forks above the Strut and carefully slide the lifting straps over each fork. Slowly raise the forks until there is tension in the straps and check that the straps are fully taught.

Wheel Chock
Step 3. Removing the Strut From its Pallet
Continue lowering the Strut section until the jack wheels contact the ground. Insert a pair of wheel chocks (or similar object) to prevent the wheels from rolling. Lower the drop jacks until the
yellow stripe is no longer visible. Lastly, attach a rope or cable to the upper angle of the diaphragm and fasten it to the backstop of the forklift. The length of the tied off rope should be
about 8-12" (200-300 mm) longer than the fork length.
Carefully lower the forks while slowly reversing the forklift. This will bring the rear of the strut down to the ground. Continue lowering the Strut rear until the drop jacks come in contact with
the ground.

Step 4. Leveling Strut
Once the Strut section is down on all 4 wheels, the lifting straps and rope can be removed. Move the forklift to the front end of the Strut and lift from the lower tube so the jacks can be
lowered. Level the Strut so that it is 12" +/- 1" (304.8 +/- 25.4 mm) above the ground.
