1. Place the two weight “cubes” in their “final resting spots.” The cubes will be
approximately 11’4” apart as shown in Figure 3.

Figure 3. Set the weight stack cubes.
2. Bolt on the teardrop pulleys above the benches (see Figure 4) on both cubes
using two 3/8” x 2-3/4” hex head bolts (used to bolt the cross beam to the cross
members and the adjustable pulley tops to the top beams). Include the 3/8” flat
washer, end cap washers, end caps and 3/8” Nyloc (locknut). Use the bolt
configuration shown in Figure 5. You may wish to use a pinch bar to align the bolt
holes.

3. Bolt on the connecting beam (part 4 from Figure 2) using a 5/8” socket with
extension and combination wrench, to the cubes using two of the large 7/16” x 6”
bolts, 7/16” washers, and 7/16” nuts, end cap washers and end caps. Figure 7 shows
the connected cubes.

4. Mount the 56” lat tops (part T) to the cells using a 5/8” socket and combination
wrench by inserting two of the large 7/16” by 6” bolts using the hardware configuration
shown. Mount the 29” tricep tops (part U) to the frame and connecting beam (See
Figure 7). Use the hardware configuration shown. You will need to remove the pulleys
from the teardrop pulley assemblies to gain clearance for the socket wrench
extension. Leave the pulleys out of the housings until the cables have been installed.

Figure 8. Mount rubber bumpers and the weight stacks.
5. Install the weight stacks. To do this:
A. Using a 9/16” socket and combination wrench, remove the tricep back rest bolts
(see Figure 9).
B. Using a 9/16” socket and combination wrench, unbolt the top plate and remove
the guide rods (see Figure 9).
Figure 9. Remove the tricep back rest, the top plate and the guide rods.

C. Prepare the weight stack. Slide the guide rods (2) through the weight stacks (1)
as shown below. Place rubber bumpers (3) on the bottoms of each guide rod.
Make sure the pull pin (4) is in the bottom weight plate.
D. Flip over the weight stacks. When shipped, the weight stacks have the pull pins
facing upward. You will need to flip the stacks over so that the pull pins are facing
outward when they are loaded onto the machine. Since the pull pins will be facing
downward when they are flipped over, it is recommended that you put the stacks
on a padded carpet to keep the pins from being damaged.
E. Set the weight stacks onto the machine. Using a piano dolly, lift the weight
stacks over the bottom plate and set the stacks onto the rubber bumpers with the
plate numbers facing outward. The 300 lb weight stacks need to be facing the
“sides” of the cells (where the benches will be attached- number 8 in Figure 9).
The 190 lb weight stacks will need to be facing the “outsides” and “insides” of the
cells (where the tricep pulleys and crossover pulleys will be attached- number 9 in
Figure 8). Make sure the pull pins are facing outward.
C. Prepare the weight stack-
add bumpers to bottom, insert
guide rods, put pull pin in
bottom stack. D. Flip over the weight stack
onto piano dolly. E. Hoist the weight
stack onto the machine.
Figure 10. Install the weight stacks.
F. Bolt on the top plate to the top of the cells with the top plate on the guide rods
as shown in Figure 11 using a 9/16” socket and combination wrench and the 3”
bolts (with cap washers) that were previously inserted.
Figure 11. Bolt on the top plate.

6. Bolt the floating pulleys into the 190 lb weight stacks used for the crossovers
using a 7/8” combination wrench. You will need to remove the pulley from the housing
to thread the plug into the weight stack bayonet. Make sure the 9/16” jam nut is
threaded 1-5/8” away from the pulley as shown in Figure 12. Leave the pulleys out
since you will need to have them out when the cable is routed.
Figure 12. Bolt the floating pulleys into the crossover 190 lb weight stacks.
7. Mount the seated row and lat benches to the frame. Using the bolts specified in
Figure 14 and a 9/16” socket and combination wrenches, mount the benches as
shown in Figures 13 and 14.

INSTALLING THE CABLES
The SM80 uses eight cables. There are three different types of cable used on the SM80. They
are:
1. Crossover cables (ball end cables) (2).
2. Low row cable (the long cables) (2).
3. Lat pulldown and tricep cables (4).
The lat and tricep cables can be identified by their short length, the low row cables can be
identified by their long length and the adjustable crossover cables can be identified by the ball
on the end of the cable. The routings for these cables are shown in the figures below.
NOTE: YOU MUST REMOVE ALL PULLEYS TO ROUTE THE CABLES.
USE A 9/16” COMBINATION WRENCH AND SOCKET TO DO THIS
(SEE FIGURE 15). YOU MAY WISH TO REMOVE THE SHOULDER
BOLTS (FIGURE 15 RIGHT SIDE) BY USING A 3/8” COMBINATION
WRENCH AND A 1/8” HEX KEY WRENCH. WHEN YOU HAVE
ROUTED THE CABLES, REPLACE ALL PULLEYS AND PLACE
END CAPS ON NUT AND BOLT ENDS. YOU MAY NEED TO PRY
THE PULLEY HOUSINGS OPEN TO REPLACE THE PULLEYS.

CROSSOVER CABLE ROUTING
Once you’ve removed the pulleys as described previously, route the two crossover cables as
shown in Figure 16.
Figure 16. Crossover cable routing.
LOW ROW CABLE ROUTING
Route the low row cables as shown in Figure 17.

Bolt the cable to the weight stacks as shown in Figure 18. Thread the 7/8” nut up on the
cable bolt as shown at left. Screw the bolt down into the weight stack as shown at right.
Tighten the bolt with a 7/8” combination wrench.
Figure 18. Screw the cable into the weight stack.
LAT PULLDOWN CABLE ROUTING
Route the lat pulldown cable as shown in Figure 19. Screw the cable into the weight stack as
shown previously in Figure 18.

TRICEP PUSHDOWN CABLE ROUTING
Route the tricep pushdown cable as shown in Figure 20. Screw the cable into the weight stack
as shown previously in Figure 18.
