Trac 20 Assembly Manual — Dp Dual
Before loading weight plates onto the machine, perform a mandatory safety check:
This is deliberate. The aluminum alloy components (typically 6061‑T6) have different thread lockers (pre‑applied blue Loctite on steel screws). If they printed absolute torques, a user with a cheap torque wrench could strip the softer aluminum.
This is the most crucial step. The DP Dual Trac 20 features a dual resistance pulley system with a 180-degree extended range of motion . Carefully thread the main cable from the weight stack through the lower, then upper, and then front pulleys according to the cable routing diagram in your manual. Make sure the cable is seated properly in all pulley grooves before attaching the clips and the lat bar. Dp Dual Trac 20 Assembly Manual
At first glance, a product assembly manual is a lowly thing—a few folded sheets of pictograms, torque warnings, and part lists. But for the , a heavy-duty dual-monitor desk mount capable of supporting two 20‑inch displays (or larger, up to 27 inches, depending on weight), the manual is a compact engineering textbook. It encodes decisions about leverage, friction, materials, and human biomechanics.
Spray a thin layer of silicone lubricant onto a paper towel and wipe down the weight guide rods. This ensures the plates glide smoothly without sticking or stuttering. Never use WD-40 , as it attracts dust and gums up the mechanism. Before loading weight plates onto the machine, perform
Drop the cable down through the top crossmember so it hangs directly above the weight stack.
Gently tap the plastic or rubber end caps into the open ends of the stabilizer tubes using your rubber mallet. Step 2: Vertical Uprights and Weight Stack Guide Rods This is the most crucial step
Test the range of motion. Sit on the bench and cycle through the butterfly/press arms to ensure movement is fluid and the cables/weights (if applicable) engage properly. Important Safety and Maintenance Tips
Over time, cables naturally stretch. If the weight stack pin does not engage because the top plate is lifting, adjust the slack. You can reduce slack by moving the cable hook down a link on the tension chain, or by tightening the adjustable pulley brackets if your version features them.
