The selector pin can be easily inserted into each of the weight plates.
The add-on weight is engaged when the latch is in the down posi-
tion.
At least six turns of the threads on the cable bolt extend into the
add-on weight selector stem.
The distance from the underside of the jam nut to the top of the washer

Complete the Assembly
IMPORTANT
As oor materials vary, it is important that you consult a licensed contractor to advise you on proper bolting techniques and appropriate fastener
types.
Standards can be changed or updated. Precor recommends that you keep apprised of your local industry standards. Precor shall not be liable for fail-
ure to properly secure and bolt strength equipment to the oor.
Precor recommends that the strength equipment be bolted down at all anchoring points. Adjust the round feet on the frame up or down by turning them left or right to help level the
equipment.
Anchor each oblong foot on the frame to the oor, including the feet on the weight stack tower. Each oblong foot has a rubber cap with slits to allow access the anchor points.
Final Checklist
• Lubricate the guide rods and chrome pad adjustment tubes with a Teon spray lubricant. Precor recommends using TriFlow brand.
• For all movable arm and pad frames, adjust and test each position. Verify that the adjustment pin fully engages and inserts freely into each position.
• Verify cables fully sit in cams (if applicable) and in pulleys. Cables should move without rubbing.
• Place the selector pin into the holder on the top plate assembly of the weight stack. Perform the exercise slowly. Verify cable moves freely without any binding. Select a
moderate weight and repeat.
• Verify the selector pin can be inserted into each weight plate.
• Verify all fasteners and the cable retention nut are tight. Ensure they meet the torque call outs in the assembly guide.
• Refer to the Maintenance Guide that came with your product for details on maintaining the equipment.
