Final Assembly and Troubleshooting
200lb Stack
Weight Stack Decals:
IMPORTANT - Check These Components Before Using
• Each Cable with a threaded bolt on either end must be
threaded at least 1/2” into its attachment, whether it be a
Free Floater, Lockout Free Floater, or the Top Plate of the
weight stack. Each must also be secured with a 1/2” Jam
Nut to ensure a safe and proper connection.
Top Plate
• Record your serial number on the front of this manual and keep for
your records. The serial number can be found on the side of the
cage as seen in the gure to the left.
Guide Rod
• Clean guide rods with a lint-free cloth and apply a thin layer of silicone lubricant (Part # BFH-50262)
to each guide rod. This will ensure a glass smooth performance from your weight stack.

Batca Fitness Systems 20 LD-4 Owner's Manual
• Adjust cables to proper tension from any of the locations shown below.
Note: All cables with threaded adjustable ends must have at least 1/2” of the threads threaded in to its counterpart.
It is very important that the 1/2” Jam Nut be wrench tightened to the counterpart to ensure that the threaded ad-
justable end of the cable does not back out of its counterpart.
• Note: If the top plate raises off of the second plate in the weight stack, then the cable tension is too tight. You will need
to take some of the tension out to lower the Top plate ush with the second plate.
