WARNING: Use of non certified “techs” note: Service warranties may be void if a non-Life Fitness-certified technician performs service work. Replacement of any strength cables should be performed by a Life Fitness certified technician.
Cabling Procedure Direct Link 1. Thread the cable into the head plate assembly at least to the jam nut. 2. Cycle the machine to ensure that it is in proper working order. 3. Check the cable to ensure there is proper tension. 4.
8. Tighten the jam nut toward the head plate assembly and frame anchor. 9. Torque the jam nuts to 20-25 FT-LBS. (27.2 - 34.0 Nm). Tensioning Cable Cable should have enough tension so it stays seated into the pulley but not so tight that it pulls the head plate off the weight plate below it.

BULGING: Internal wire rope strands can break within and coil causing a bulge to appear. Cable should retain same outside diameter throughout. FRAYED/EXPOSED WIRE ROPE: Any exposed wire rope protruding through the casing or at either end. FLATTENED: Section of cable is compressed and will not retain its shape (outside diameter).
4. Bolt to Floor Guide Introduction Life Fitness designs its products to be stable when used as designed. Because strength training is dynamic, we cannot predict how users will ultimately use the products in all circumstances. Therefore, Life Fitness recommends that strength training equipment be secured to a solid, level surface to stabilize and eliminate rocking or tipping over.
Competitor Product The bolt down guidelines and procedures for Life Fitness products were determined by the company’s Engineering and Installation Development groups. These guidelines include which anchors to use and positioning of the anchors are required for Life Fitness product.
Anchor Procedure 1. Place unit into position to be mounted and cycle unit to set its stance. 2. Wearing protective glasses, drill down into flooring perpendicularly to the required depth, ensuring that the foot thickness of the unit is being accounted for; refer to Anchor Selection and Foot Dimensions. NOTE: Use 3/8"...
