STEP # 1: P-50 MAIN FRAME ASSEMBLY
1. Place the two main pre-assembled side frames left & right respectfully opposite each other
in the center of the assembly area as shown in the Illustration. Place the Back Base Rail
(3) between the two Side Base Rails (1 & 2) so that the side pre-drilled holes of the Base
Rails (1 & 2) align with the end holes of the Back Base Rail (3).
2. Attach the two main pre-assembled side frames to the Back Base Rail (3) using two Cross
Brace Backing Plates (4), four bolts (66), eight washers (77) and four nuts (81) as shown.
HAND TIGHTEN the bolts at this time.
3. Now attach the two main pre-assembled side frames to the Top Rail (16) using four bolts
(66), eight washers (77) and four nuts (81) as shown. HAND TIGHTEN the bolts at this
time.
4. Attach Electronic Box Locating Board (11) to Back Base Rail (3) using two bolts (65), two
washers (77) and two nuts (81).
5. Tighten all bolts and nuts used for assembly in previous steps.
6. Carefully thread both Base Wire Harness's thru the center hole in the Back Base Rail (3).
7. Plug in both Base Wire Harness's into sides of Electronic Box (13).
8. Install Protective Cover (12) over Electronic Box with two screws (70).
9. Snap both Base Wire Harness's into Channels (90) and push any excess into hole in Side
Base Rails (1& 2).
10.Untie the coiled left & right Weight Bar Cables, so that they hang straight down with out
any twists or tangles. Be sure that the cables are straight and uncrossed and cables
and pulleys move smoothly.
STEP #2: SENSOR WEIGHT BAR INSTALLATION
1. Standing in front of the ProSpot Fitness® P-50. Insert one end and then the other end of
the Sensor Weight Bar (31) into the Cable Knuckles (46-48). Slide the Cable Knuckles
onto the Bar until they rest snugly against the preinstalled sensor retaining collars (45 &
48) at each end of the Sensor Weight Bar (31). (There is a rotation-limiting pin that
protrudes from the bottom of the Sensor Weight Bar (31) that must fit through a slot in the
knuckles (46-48) as it is slid into position).
2. Place one Plastic Locking Sleeve (36) onto each end of the Sensor Weight Bar (25) and
slide them inwards until they butt up against and secure the Weight Bar Cable Knuckle in
place. Tighten Plastic Locking Sleeve bolts securely with 4mm Allen wrench (95) provided.
3. Place one of the Olympic Adapters (32) onto the Sensor Weight Bar (31) and slide them
onto the Bar, then insert the Weight Bar Shoulder Bolt (34) onto each end of the Sensor
Weight Bar (31). Secure with provided 9/16" Allen wrench (97).

Safe Use of Your ProSpot Fitness® Product
1.
CAUTION:
This machine involves the risk of possible injury by its user.
THE FOLLOWING RULES SHOULD BE CARFULLY FOLLOWED:
Consult a physician or other healthcare provider before beginning an exercise
program.
If you are in bad health or are handicapped, ask for the opinion of your
physician and exercise only under qualified supervision.
Discontinue to exercise if you experience any light-headedness, dizziness or
shortness of breath and consult your physician.
2.
Keep small children and others at a safe distance from all moving parts. The
up and down movement of the weights can be dangerous. Never allow your
fingers, toes, hair, other body parts or loose clothing to come near weights
while they are in motion. Never attempt to exercise with more weight than
you are physically able to handle. Periodically inspect your machine to ensure
all parts are free from defect and are fully operational. Check all fasteners to
make sure none have loosened with use. Tighten any loose fasteners if
necessary.
3.
Warning: Never perform any maintenance on the unit while the power
supply is plugged into the wall.

User Instructions for the ProSpot Fitness® P-50
Do not allow any liquid to be near the machine or spilled on any electrical part. Do not insert any
foreign object into the electrical box or attempt to open it. If you have any questions or need help refer
1. Connect the power supply to a standard 110-volt household current. While connecting the
power supply do not touch the barbell as this may interfere with the computer’s initial settings.
If you need to reset the computer, simply unplug the power supply, wait 45 seconds and
reconnect it. It is recommended that surge protection be used to help protect and extend the life
of the Electronic Box of the unit from power surges and lightening strikes. A flashing green
light will appear on the Electronic Box when power is on.
Become familiar with the Grab and Go® operation BEFORE placing weights on the barbell.
2. Position the Spot Blocks: Before positioning the Spot Blocks, place the barbell into the lowest
position for the exercise you will be performing. Move the barbell by grasping it and raising it
1” to unlock. While grasping the barbell raise or lower it into the desired position. Open hands
to lock the barbell in place. To move the Spot Blocks, place your index and middle fingers
underneath the finger grip and your thumb on the push-release lever. Push in the push-release
lever with your thumb and move the Spot Blocks so that they are touching the top of the slider-
locking block (the black block with the ProSpot Fitness® logo on it). Release the push-release
lever to lock the Spot Block in place.
3. Assume a normal starting position for your desired free-weight exercise.
4. Grasp the barbell:
I. Rotate the barbell so that the Touch Sensor Strip embedded in the barbell is touching
your fingertips. It is necessary for your fingertips to maintain skin contact with the
Touch Sensor Strip throughout your free-weight exercise.
II. Learn the Rule Of Thumb: Sometimes referred to as a “false grip” or “sissy grip”,
ProSpot’s Rule Of Thumb is a style of grip in which the thumb does not wrap around
the bar but rests alongside the index fingers. Using this type of grip with your ProSpot
Fitness® equipment will prevent your thumb from maintaining skin contact with the
Touch Sensor Strip when you attempt to lock the bar in place.
III. Once you have grasped the barbell, you will hear a soft ‘click’ and a solid red light will
appear on the Electronic Box in addition to the flashing green power light.
5. While still grasping the barbell, lift about 1”, using an even upward lifting motion on both sides
of the barbell. This upward movement will disengage the locking mechanism. If you have
performed this step correctly, the barbell will now be under your control, the cables will move
freely over the pulleys and the slider knuckles will slide smoothly up and down the guideposts.
You can now safely perform any free-weight exercise without the need of a spotter. Simply
Grab and Go®!

6. Locking the barbell in place: When you are finished with using the barbell, open your hands to
remove your fingertips from the Touch Sensor Strip at the same continue to support the barbell
with your palms. (Make sure no other skin contact is being made with the Touch Sensor Strip.)
Slowly lower the barbell until it locks into position. There is a locking position every 1”. Now
remove your palms from the barbell. The barbell is now locked and ready for your next
exercise.
7. Always maintain control of the movement of the barbell. Do not allow the barbell to swing
against the machine frame, as this may cause damage to the finish. Do not attempt to throw or
slam the barbell attached to the cables, as this may result in damage to the locking mechanism.
Intentional misuse of the P-50 will void any and all warranties.
Once familiar with the Grab and Go® operation, you can now begin using the barbell with weight
plates.
8. Position Spot Blocks for the desired exercise. (Refer to #2 above.)
9. Make certain the barbell is level before loading weight plates. Level the barbell by raising up
one end of the barbell until it is level. (The P-50 is equipped with a ratcheting feature that
allows the barbell to be manually raised from side-to-side.) Or, level the barbell by grasping it
with both hands, making sure the fingertips make contact with the touch sensor strip. Lift the
barbell upward about 1” to release it from the locking mechanism and place it in a level
position. Once the barbell is level, open your hands to lock it in place. Load weights evenly
on both sides of the barbell.
10. Secure all weight plates with a spring clip or locking collar. You are now ready to begin your
free-weight exercise routine.
11. Perform your exercise following the steps outlined in #2-6 above.
12. Before removing the weight plates from the barbell, make sure it is in a level position.
13. Never attempt to lift more weights than you can safely handle. Never put more than 350
pounds on the barbell.

Trouble-Shooting Guide
How the Patented ProSpot Fitness® System Works:
Starting from the Computer Brain, a signal is sent from the left & right side, thru the L & R Grey Base
Frame Wire Harness (white lead), to the Spiral Cord Harness (brown lead), to the Slider Block Cable
Knuckle connector, to inside Barbell Cable to the Sensor on the Barbell. When skin contacts is made
with Barbell Sensors, the signals return to the Computer Brain, at which a 12-volt charge is sent via the
wire harness's (red & black leads), to the solenoids, to release the spring loaded Slider Block Locking
Pins when the Barbell is lifted, allowing the Barbell to move up and down. When skin contact with
Barbell Sensor is broken by either hand, the Computer Brain reads this and stops the 12-volt charge to
the solenoids, at which time, the spring loaded Locking Pins instantaneously engages the hole on the
Guide Post and locks the Barbell from any downward movement.
ALWAYS REMEMBER: After performing any service on the unit, RESET the Computer
on your ProSpot system before using it. Just unplug the power supply Electronic Box, wait 30
seconds and plug back in. Resetting the Computer allows it to recalibrate and work to its greatest
efficiency.
