DO NOT fully tighten the fasteners until instructed to do so.
Remove shoulder pad pivot supports
Disconnect the pre-assembled shoulder pad assemblies (Figure 1).
Assemble the frame
1. Place the base frame on the oor 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
3. Attach the center frame to the base frame using two bolts and washers
and to the rear upright using two bolts and washers .
4. 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).
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, shoulder frame and placards
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 .
Figure 4
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 .
4. Fully tighten all bolts to 65 ft-lb (88 N-m).
Attach the shoulder frame:
1. Slide the shoulder pad assembly tube onto the shaft (Figure 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).
Figure 5
5. Ensure the shoulder pad assemblies are aligned with each other. If they are
not, adjust the rod end length as necessary. Once aligned, remember to
center the rod end in a rotational manner. While preventing the rod end
from turning, tighten the jam nut (Figure 6).
Not aligned Aligned

7. Attach each shoulder pad using three screws and washers (Figure 8).
Fully tighten the bolts.
Attach placards
1. Attach the long placard using four bolts and four washers (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.

2. Slide the selector tube pin through the brackets, bumpers , rod end, and
secure it with the bolt and washer .
3. Repeat Steps 1 and 2 to attach the height adjustment assembly top rod end
to the shoulder frame (Figure 12).
When assembly is complete, check to ensure that the Adjustable Height Calibration
functions properly.
Check the 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 clockwise, ½ turn (Figure 13). Then tighten the
jam nut and retest.
Figure 13
b. Continue this process until the pop pin does not release with the
handle depressed.
NOTE
In rare cases, it may be necessary to adjust the nut in ¼ turn increments to
meet both retest checks.
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
Attach weight arm horns

(Figure 17).
Figure 17
2. Secure the weight horn using a bolt and washer .
3. Place a set screw into the horn assembly and tighten.
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 the 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.
To stabilize the equipment:
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 the oor
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
gure). Replace end caps when bolting is complete.
As oor materials vary, it is important that you consult a licensed contractor to
advise you on proper bolting techniques and appropriate fastener types.
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 oor.
