instructed to do otherwise.
•As you assemble the weight system, make sure
all parts are oriented as shown in the drawings.

The following tools (not included) are required
for assembly:
• two adjustable wrenches
• one rubber mallet
• one standard screwdriver

Make Things Easier for Yourself
Everything in this manual is designed to ensure
that the weight system can be assembled suc-
cessfully by anyone. However, it is important to
