CHAPTER3: Preventative Maintenance
3.1 Preventative Maintenance Checklist
Preventative maintenance and daily cleaning will prolong the life and look of your Matrix Fitness Systems
equipment.
ACTION FREQUENCY
Clean Upholstery Daily
Inspect Cables Daily
Clean Guide Rods Monthly
Inspect Hardware Monthly
Inspect Frame Bi-Annually
Clean Machine As eeded
Clean Grips As eeded
Clean Linear Bearing Guide Rods (Calf Press and Leg Press only) As eeded
Lubricate Linear Bearings (Calf Press and Leg Press only) As eeded or every 1.5 million cycles
Lubricate Guide Rods As eeded
Upholstery and grips should be cleaned with a non-ammonia based cleaner (like Simple Green) or a mild
soap and water. Guide rods should be lubricated with Teflon based lubricant. Apply the lubricant to a cotton
cloth and then apply up and down the guide rod.
Linear bearings should be lubricated with a SKF LGMT 2 grease.
3.2 Rep Counter Information
To see the accumulated reps or hours:
1) Hold a magnet to the outside of the rep counter face plate over the clock for 5 seconds to activate Service
Mode.
2) The rep counter will read r0 in the left window and the first 3 digits of the total reps in the right window
(Figure A), record this information.
3) After 3 seconds, the rep counter will switch to r1 and the next 3 digits of the total reps are shown in the right
window (Figure B). Record this information.
4) If there are further digits in the total reps, the rep counter will switch to r2. Record this information.
5) Combine the r values to determine the total reps. Using Figures A & B below, the unit would have 237,145
total reps.
6) Once the complete number of total reps has been displayed, the rep counter will flash c0 and the first 3

5
digits of the accrued hours of use are shown (Figure C).
7) After 3 seconds, if there are more digits in the accrued hours, the rep counter will switch to c1 (Figure D).
8) Combine the c values to determine the accrued hours. Using Figures C & D below, the unit would have
1,209 accrued hours.
9) Remove the magnet from the rep counter to reset to normal function.
TOTAL RESET
1) To reset all data on the rep counter, three magnets must be simultaneously held to all 3 reed switches (2 in
the stack and one in the faceplate) for 5 seconds. This clears all recorded data and cannot be recovered.
LOW BATTERY
1) When the rep counter battery gets low, the display will read Lo bAt (Figure E). At this point, the battery
needs to be replaced. This WILL NOT erase the Service Mode data.

CHAPTER6: Troubleshooting
6.1 Troubleshooting – repetition counter issues
THE REPETITION IS BLANK OR IS NOT COUNTING MOVEMENTS.
Possible Causes
1) The rep counter battery is dead or disconnected.
2) The rep counter is unplugged from the repetition sensors.
3) The magnet is missing or miss-positioned.
4) The repetition sensors are faulty or miss-positioned.
5) The rep counter is faulty.
Solution
1) Remove the 4 screws holding on the aluminum wing and top cover. Check that the battery for the rep
counter is firmly seated and has a charge. Replace the battery if needed.
2) Check the connection of the wiring coming from the repetition sensors to the rep counter (Figure A).
3) Check that the magnet is present and in a position to be read by the repetition sensors (Figure B). The
magnet should be slightly off the center of the sensors.
4) If the rep counter displays a value, but is not counting repetitions, check the position of the sensors. The
sensors should be positioned depending on the model according to the chart on the following page. If the
rep sensors are positioned correctly and still not reading, replace the repetition sensors (Figure C).
5) If the repetition sensors and battery have been replaced and the issue is still present, replace the rep
counter.

6.2 Troubleshooting - incremental weight pin issues
INCREMENTAL WEIGHT PIN IS LOOSE OR FEELS SLOPPY
Possible causes
1) The snap ring holding the incremental weight pin in position is damaged or missing.
2) The incremental weight pin is damaged.
Solution
1) Remove the weight stack covers.
a. Remove the 4 screws holding the clear plastic cover over the incremental weight pin and remove the
clear plastic cover.
b. Check the incremental weight pin for damage, replace if needed.
2) Check if the snap ring and washer holding the incremental weight pin to the stack is in place (Fig. A & B).
a. If this snap ring is missing, install a new snap ring.
b. If the snap ring is in place, but not holding the incremental weight pin in place, it may not be properly
installed in the groove in the pin.
c. If the snap ring is in place and properly installed in the groove, but the pin is still loose, replace the
snap ring (the ring may be too stretched out to be affective).

15
6.3 Troubleshooting - arms
ARMS ARE NOT EVEN AT THE STARTING POSITION
Possible Causes
1) The arm tie rods are uneven.
2) The arms are bent or uneven.
3) The frame is bent or uneven.
Solution
1) The tie rods on the Shoulder Press, Chest Press, Lat Pull Down and Seated Row are adjustable.
a. If the arms are uneven, loosen the jam nuts and adjust the tie rods as needed to level the arms.
Tighten the jam nuts to hold the arms in place.
2) Place a level along multiple points on each arm to determine if the arms are bent or if it is the frame.
a. Replace the unit or arms as needed.

16
6.4 Troubleshooting - weight stack pin issues
WEIGHT STACK PIN WILL NOT GO INTO SOME OR ALL WEIGHT PLATES
Possible Causes
1) The weight stack pin is bent.
2) The cable is attached too loosely or too tightly.
3) The weight plates are not seated correctly at the bottom of the guide rods.
4) The top weight plate bushings are damaged.
Solution
1) Check the weight stack pin for straightness. Replace if needed.

6.5 Troubleshooting - cable is failing off a pulley or cam
THE WEIGHT STACK CABLE IS FALLING OFF A PULLEY OR CAM
Possible Causes
1) The cable is too loose or too tight.
2) The cable is routed incorrectly.
3) A cable retainer needs to be added to the Hip Abductor, Hip Adductor and Leg Press (See Sections 6.6
and 6.7).
Solution
1) Check the tightness of the cable. Make sure that it is tensioned as outlined in Section 3.2.
2) Check the routing of the cable through the weight stack.
a. Make sure that the cable is not routed around a stand off in the weight stack frame (Figure A).
b. Follow the routing of the cable. The cable should be centered on pulleys and cams before being
tensioned.
3) If the unit is a Hip Abductor, Hip Adductor or Leg Press, see Sections 6.6 & 6.7 for instructions on adding a
cable retainer.

6.7 Troubleshooting – repetition counter magnet missing or failing off
REPETITION MAGNET HAS FALLEN OFF OR IS MISSING
Possible Causes
1) The repetition counter magnet was not secured tightly enough to the repetition counter bracket.
Solution
1) Install a zip tie to securely attach the magnet to the bracket (Figure A).
2) When installing the zip tie, make sure that the head of the zip tie is on the opposite side of the bracket from
the magnet so that the head does not interfere with the movement of the top weight plate (Figure B).
6.8Troubleshooting - ROM plunger or pull pins do not move easily
ROM PLUNGER OR PULL PINS DO NOT MOVE EASILY
Possible Causes
1) The pins are rubbing on the frame creating friction.
Solution
1) Remove the affected pin, add grease (Matrix recommends SuperLube brand grease with PTFE) and then
re-install the pin.

20
6.9 Troubleshooting - seat loose or will not spring up
SEAT IS TOO LOOSE OR NOT SPRINGING UP
Possible Causes
1) The swirl springs are miss- positioned or missing from the connecting rods.
2) The swirl springs are broken in the connecting rods.
Solution
1) Remove the bottom seat connecting bars (Figures A & B) and check that the swirl springs are present
and in working order, on the bottom connection point (there should be at least 2 swirl springs for each set
of 4 connecting rods) (Figure C).
2) Re-install the seat connecting bars being careful to correctly orient the swirl springs so that they contact
the stopper bar and provide spring when the seat pad is adjusted up (Figure D).
