DO NOT attempt assembly by yourself.
When assembling the equipment, we recommend you:
lFollow the steps in the order listed in this assembly guide.
lUnpack the box and assemble the equipment close to where you plan to use it.
lLocate the equipment at least 40 inches (1 meter) away from walls or furniture on either
side of the equipment, and 40 inches (1 meter) away from objects behind or in front of the
equipment.
lAssemble the equipment on a solid, flat surface, so that it remains level and stable.
Required tools
lTorque wrench
l18 mm open-end wrench
lRubber mallet
l19 mm open-end wrench
Begin Assembly
NOTE DO NOT fully tighten the fasteners until instructed to do so.
Remove shoulder pad pivot support
Disconnect the pre-assembled shoulder pad assemblies (Figure 1).
Figure 1
Assemble the frame
1. Place the base frame on the floor where you plan to
use the equipment.
2. Attach the rear upright to the base frame using four
bolts and washers (Figure 2).
Figure 2
4. Attach the center frame to the base frame using two bolts and washers and to the
rear upright using two bolts and washers. Fully tighten all bolts.
5. In the center frame bracket, position the
shoulder frame support pivot to align the
bracket and frame openings. Slide the short
axle through the base of the shoulder frame
support and attach the shoulder frame support
using two bolts and two end caps (Figure
3). Figure 3
NOTE The axle should slide easily through the openings. If it does
not, use a rubber mallet to gently tap it through the opening.

Attach moving arms
1. Position the weight arm pivot tube in line with the bottom holes in the rear upright
bracket. Ask your assistant to hold it level while you slide the axle with the center groove
through the bracket and secure it using two bolts and two washers .
2. Position the cable arm pivot tube and long-
stemmed rubber bumpers in line with the
middle holes in rear upright bracket. Ask your
assistant to hold it level while you slide the axle
through the bracket and secure it using two
bolts and two washers .
3. Position the shoulder frame pivot tube and
short-stemmed rubber bumpers in line with the
top holes in the rear upright bracket. Ask your
assistant to hold it level while you slide the axle
through the bracket and secure it using two
bolts and two washers . Figure 4
3. Fully tighten all bolts to 65 ft-lb (88 N-m).
Attach shoulder frame
1. Slide the shoulder pad assembly tube onto the shaft (Fig-
ure 5).
2. Secure it using one bolt and one end cap (Figure 5).
3. Repeat Steps 1 and 2 to attach the other shoulder pad
assembly tube. Fully tighten the bolts.
4. Reconnect the shoulder pad assembly back through the
rod end (Figure 5).
5. Ensure the shoulder pad assemblies are aligned with
each other. If they are not, adjust the rod end length as
necessary. Figure 5
6. Once aligned, place the arm on the Safety Stop. Center the rod end in a rotational manner,
while preventing the rod end from turning, tighten the jam nut.
Not centered Centered
Figure 6 Figure 7
7. Repeat step 4 to attach the other shoulder pad assembly.
Test each moving arm to make sure it moves smoothly
through its range of motion.
8. Attach each shoulder pad using three screws and wash-
ers (Figure 8). Fully tighten the bolts.
Figure 8
Attach placards
1. Attach the long placard using four bolts and four wash-
ers (Figure 9). Fully tighten the bolts.
Figure 9
2. Attach the short placard by sliding it onto the placard
holder and secure it with one bolt and one washer
(Figure 10). Fully tighten the bolts

Assemble height calibration
1. Place a bumper on either side of the height
adjustment assembly bottom rod end and pos-
ition it inside of the weight arm bracket (Figure
11).
Figure 11
2. Slide the selector tube pin through the brack-
ets, bumpers , rod end, and secure it with the
bolt and washer .
3. Repeat steps 1 and 2 to attach the height adjust-
ment assembly top rod end to the shoulder
frame (Figure 12).
Figure 12
Check height calibration
1. Unload the shoulder frame by lifting it slightly. When the release handle is depressed, the
pop pin should release. Ensure this happens at each height adjustment position.
a. If the pop pin does not release in all positions, loosen the jam nut and turn the
adjustment nut counter clockwise, ½ turn (Figure 13). Then tighten the jam nut
and retest.
b. Continue this process until the pop pin releases at all heights when the load is
removed from the shoulder frame.
2. Remove all weights and lift the weightless shoulder frame. Depress the release handle.
The pop pin should not release with this load.
a. If the pop pin releases the weight arm, loosen the
jam nut and turn the adjustment nut clock-
wise, ½ turn (Figure 13). Then tighten the jam nut
and retest.
NOTE In rare cases, it may be necessary to
adjust the nut in ¼ turn increments to
meet both retest checks.
Figure 13
Attach foot plate
1. Position the foot plate onto the base frame.
2. Secure the plate using two bolts (Figure 14). Fully
tighten the bolts.
Figure 14
Attach weights arm horns
1. Slide the weight horn through the
bumper and into the weight arm (Figure
15).
2. Position the second bumper against the
inside of the weight arm and attach the
horn using one bolt . Fully tighten the
bolts. Figure 15
Attach counter weights
1. Slide the counter weight into the back of the
shoulder frame and secure it use two bolts and
washers (Figure 16). Fully tighten the bolts.
Figure 16
Attach weights storage horns
1. Insert the weight horn into the hole in the rear
upright frame until it stops (Figure 17).
2. Secure the weight horn using a bolt and
washer .
3. Place a set screw into the horn assembly and
tighten.
Figure 17
4. Push the storage horn bumper into the weight horn with its wide side facing outward. If
needed, use a weight plate to push the bumper against the equipment frame.
5. Repeat this procedure to attach the other weight horns.

Stabilize equipment
Once you have assembled the equipment, test its stability by pushing down on each corner. If the
base frame rocks or wobbles, you need to adjust the feet to stabilize it.
1. Locate the round, adjustable feet on the bottom of the equipment frame.
2. Using a 19 mm open-end wrench, turn the positioning bolt to the left or right to level the
equipment.
To move the adjustable foot ... Then turn the bolt ...
Upward To the right
Downward To the left
3. Continue to test the corners of the equipment and readjust the feet as needed.
4. When the equipment is stable, re-tighten the jam
nut with an 18 mm open-end wrench to 600 in-lb
(67.79 N-m).
5. Insert the frame end cap and secure it using two
M6 × 60 mm socket head cap screws. Tighten the
screws to 10 in-lb (1.12 N-m) of torque (Figure
18).
Bolt equipment to floor
Precor recommends that the strength equipment be bolted down at all
anchoring points. Bolting is made possible by removing the end caps at
the frame base and exposing the mounting holes that accommodate the
bolts (see the accompanying figure). Replace end caps when bolting is
complete.
NOTE As floor materials vary, it is important that you consult a licensed contractor
to advise you on proper bolting techniques and appropriate fastener types.
CAUTION Standards occasionally change or are updated. Precor recommends
that you keep apprised of your local industry standards. Precor shall not be held
liable for failure to properly bolt the strength equipment to the floor.
