WARNING: ONCE YOU UNBOLT THE BOTTOM SHIPPING BOLTS AS
DESCRIBED BELOW, THE SIDE PIECES OF THE MTS SHOULDER PRESS ARE
UNSTABLE AND WILL WANT TO FALL. THEY SHOULD BE SUPPORTED WHILE
THE BOLTS ARE REMOVED.
4. Using a ½” socket wrench, unbolt the bottom lag bolts on the left side as shown in Unpacking Figure 2.
“Walk” the side off of the shipping crate onto the floor. Make sure the side is stabilized as it will tip over
easily. Repeat this step for the right side piece. Remove and discard the shipping pallet and the lag bolts.

CAUTION: THE SIDES OF THIS MACHINE ARE NOT STABLE UNTIL THE BOTTOM
BRACE AND BACK BRACE HAVE BEEN INSTALLED AND THE BOLTS HAVE
BEEN TIGHTENED.
NOTE: THIS EQUIPMENT IS DESIGNED TO BE STABLE DURING NORMAL USE.
HOWEVER, IN ORDER TO INSURE THE SAFETY OF PERSONNEL DURING POTENTIAL
MISUSE OF THE EQUIPMENT, LIFE FITNESS STRONGLY RECOMMENDS THAT THIS
EQUIPMENT BE SECURELY FASTENED TO THE FLOOR. USE ½” (12mm) FASTENERS
COMPATIBLE WITH THE FLOORING MATERIAL OF THE FACILITY.
1. Bolt together seat assembly. The seat assembly is shipped in two pieces. Fasten the seat post to the seat
assembly as shown. Use the bolts that are on the seat post as shipped.
Assembly Figure 1. Build the seat assembly.
2. Bolt the bottom to the left side and right sides of the MTS SHOULDER PRESS. As shown in Figure 3,
slide the bottom up to the left side of the MTS SHOULDER PRESS and bolt them together using two of the
1/2” x 4-1/4” hex head bolts with hammerhead washers on the outside of the frame. Insert the bolts from the
outside of the MTS SHOULDER PRESS. Put on star washers before threading the locknuts and hand tighten
the locknuts so that the back brace will be easier to install. Slide the right side of the MTS SHOULDER
PRESS up to the base and bolt it to the base using two more ½” x 4-1/4” hex head bolts with hammerhead
washers on the outside of the frame.

7. Run the belts through the arm pulleys and bolt down the belts. Thread the belts from the weight
stacks through the arm pulleys to the belt plate. With the weight stack pin in the bottom (150 lb.) plate, pull
the belt until it’s tight. Use the 3/8” x 1-1/4” bolts and plates (circled) and tighten down the belt to 20 ft/lbs.
Cut off the belts leaving about one inch beyond the belt plate. Use a heavy scissors or utility knife to
cut off the belt.

To apply the weight plate stickers:
1. Peel off the backing.
2. Line up sticker backing edge with holes as shown in the figure. Make sure you’ve aligned the sheet so
that the top hole in the stack (the one that holds the weight stack pin) DOES NOT get a sticker.
3. Make sure the sheet of labels is straight.
4. Press down.
HAMMERHEAD WASHER LOCATIONS

Assembly Figure 11. Hammerhead washer locations (6 total).
Assembly Figure 11 shows the bolt connections on the MTS SHOULDER PRESS that need hammerhead
washers. There are 6 hammerhead washers that need to be installed in the field. They are found on the back
frame seat connection (2) and on the side/back frame connection (4). Hammerhead washers on the shields
and arms have been installed at the factory.

CLEANING THE SHIELDS
The shields on the MTS machine are made from LEXAN. Adherence to regular and proper cleaning
procedures is recommended to preserve the appearance.
Washing To Minimize Scratches
Wash LEXAN with a mild soap or detergent (e.g. Joy Dishwashing Liquid) and lukewarm water
using a clean sponge or a soft cloth. Rinse well with clean water. Dry thoroughly with a
chamois or moist cellulose sponge to prevent water spots. Do not scrub or use brushes on
these products; their coating is UV-resistant, not mar-resistant.
Fresh paint splashes, grease and smeared glazing compounds can be removed easily before
drying by rubbing lightly with a grade of VM&P naphtha or isopropyl. Afterward, a warm final
wash should be made, using a mild soap or detergent solution and ending with a thorough
rinsing with clean water.
Minimizing Hairline Scratches
Scratches and minor abrasions can be minimized by using a mild automobile polish. Four such products that
tend to polish and fill scratches are: Johnson Paste Wax, Novus Plastic Polish #1 and #2, Mirror Glaze plastic
polish, and Plexus. It is suggested that a test be made on a small corner of a shield with the product selected
and that the polish manufacturer’s instructions be followed.
Some Important “Don’ts”
•DO NOT use abrasive or highly alkaline cleaners on the shields.
•Never scrape shields with squeegees, razor blades or other sharp instruments.
•Benzene, gasoline, acetone or carbon tetrachloride should never be used on the shields.
•DO NOT clean shields in hot sun or at elevated temperatures.
Compatible Cleaners For Shields
The following cleaning agents have been found compatible with LEXAN. The manufacturer’s
recommendations and instructions should be followed. They are: Joy, Freon T.F., Palmolive Liquid, Top Job,
VM&P grade naphtha, Windex with Ammonia D.
Removal Of Paint, Marking Pen, Labels
Butyl cellosolve works well for removal of paints, marking pen inks, lipstick, etc.
Labels, stickers, etc. may be removed using kerosene or VM&P naphtha. When the solvent will not penetrate
sticker material apply heat (hair dryer) to soften the adhesive and promote removal. GASOLINE SHOULD
NOT BE USED.

3. FINAL INSPECTION
IMPORTANT: IT IS VITAL THAT THESE MACHINES LOOK AND PERFORM
FLAWLESSLY BEFORE THE INSTALLATION CAN BE CONSIDERED
COMPLETE.
Before leaving the MTS SHOULDER PRESS, look to make sure the following have been completed:
1. All bolts have been tightened (but not overtightened) so that at least one thread protrudes out of the
locknut.
2. Look at all Hammerhead washers and make sure their locations match those shown in the detail drawing
in these instructions.
3. All weight plates have stickers on them as shown in the figure below.

Final Inspection Figure 1. Weight plate stickers must be on correctly.
4. The usage sticker and increment weight sticker locations match the drawings in these instructions.

MTS SHOULDER PRESS Assembly Instructions
15
Final Inspection Figure 2. Usage stickers locations should match those shown above. Note which side the
weight stack stickers are on (they should be “toward the front” as the user is sitting down on the machine
so that they are easily visible).
5. The guide rods have been wiped down.
6. The shields have been cleaned as specified in these instructions.
7. All dirt and dust have been wiped off the machine.
8. The machine should be stable on the floor of the site. If any part of the machine is off of the floor, rocks, or
is wobbly, the bolts on the machine will need to be loosened and the machine readjusted.
9. The belts should be tight with about 1 inch of play. Top weight stack plate should be flat on the stack and
the weight stack pin should be able to slide smoothly into each plate hole.
10. Belts should run smoothly on the pulleys and not slide off to the sides. Belts that slide off center will need
to have the arm bolts readjusted.
