1. Use a Phillips screwdriver and two kit supplied #8 x ¾ Phillips pan head screws to attach the device holder bracket to the back of holder as shown.

 

Disassemble Hammer Strength

Some machine models may be equipped with weight stack cover shrouds and incremental weights. During the main unit and reflector tape installation, the left front shroud will need to be removed and the increment weights lowered. The following steps will show this process.

 

1. Pull the knob of the first increment weight and slowly move it down until it rests on the top weight plate, then repeat pulling the knob on the second increment weight and move it down until it rests on the first increment weight.

 

2. Use a 7mm Allen hex bit to remove the three screws securing the left shroud and place to the side

 

3. Move the shroud towards the right, then flex and turn the shroud, so it clears the incremental weight knobs and place to the side

 

Device Holder Installation

1. Measure from the floor up the frame (See Device Holder Locations table, column A) and place the bottom hole of the kit supplied device holder pivot bracket at that point, then use a center punch to make an indentation into the frame as shown.  Note: For model HS-HG see the following article Life Fitness Connect System Kit Hammer Strength HS-HG Device Holder Installation Instructions 

Warning: Use a power drill, not an impact driver.

2. Use a ¼" socket to loosely insert the first #8-18 x ¾ self-tapping screw into the bottom hole of the bracket at the center punch mark.

3. Use a level to align the bracket straight, then again use a center punch to make an indentation into the frame for the top hole

Warning: Use a power drill, not an impact driver.

4. Use a ¼" socket and again loosely insert the second #8-18 x ¾ self-tapping screw into the top hole of the bracket at the center punch mark.

5. Finally, tighten both screws of the bracket using a ¼" socket. Attention: DO NOT OVER TIGHTEN! Torque to 16-20 in/lbs. (1.8-2.2 Nm

6. PLEASE VACUUM ANY DEBRIS FROM DRILLING.

7. Take the device holder sub-assembly and align the first hole of the bracket with the center hole of the previously installed pivot bracket, then insert a kit supplied #M6-1 x 20 mm screw and #M6 flat washer as shown.

8. Loosely attach a kit supplied #M6 flat washer and #M6 nylock nut as shown on the underneath side of the bracket to the screw.

 

9. Repeat steps 2 and 3 for the second screw and hardware.

 

10. The device holder can swivel right or left. NOTE: Leave the device holder loose until the shroud is re-attached (if applicable).

 

11. Once the shroud is re-attached (if applicable), adjust the holder to the preferred position, then use a #M10 wrench or socket and #M5 allen hex bit or wrench to tighten the holder in place.

 

Device Holder Installation Complete

 

Install Main unit 

 

 

The main unit is used together with a puck on gym machines, which is equipped with a weight stack. The main unit is mounted on the top plate of the weight stack, with a free line of sight to a reflective sticker that is attached to a flat surface above the main unit. The reflective sticker is mandatory to attach on a suitable area inside the machine with a free line of sight to the main unit. The optical sensor shall move together with the weight stack in a straight line against the reflective sticker. There must be a free field of view, approximately +/- 10 degrees from the sensor against the reflective sticker. The maximum distance between the main unit in its lowest position and the reflective card at the top is 160cm/63 inches. 

 

Use the LF Assist App

The Life Fitness planner should have given you access to the facility in which you are installing. If you don't see the facility, contact the planner. They can add your account in almost real time. If you need to refresh the list after changes are made. Click on the 3 dots in the top right cover and click reload gyms 

 

1. Press the machines tab in the site overview.

2. Press the “+”-button in machines overview.

3. Open the main unit by pressing on the top and pushing it slightly downward (releasing the locking mechanism) and then slide forward (length wise). Slide the top off and lift from the case. The white label is located beside the battery pack on one side. Note: install one battery from the packaging,  You must install all four batteries properly in order for the unit to work. 

4. Slide the top off and lift from the case. Install AA batteries making sure that all 4 batteries are placed correctly. (The main unit is in sleep mode when it is stationary. Shaking the main unit will wake it up. When the unit is awake a green LED light will flash every 3rd second, emitting its MAC address. After 3 seconds of no activity it will go back to sleep.)

 

 

 

5. Take the kit supplied main unit bracket and use an alcohol pad to clean the top and bottom sides of any dirt or dust in the areas shown. NOTE: Allow at least 4 minutes for alcohol to dry.

6. Attach two of the kit supplied interlocking velcro pieces together to make one and continue this with the other four until three interlocked pieces are made, then peel off one side of the protective adhesive backing and apply them to the underside of the bracket (bent tabs pointing down) as shown.

7. Take an alcohol pad and wipe the left side area of the top weight stack of any dirt or dust as shown. NOTE: Allow at least 4 minutes for alcohol to dry.

8. Remove the protective adhesive backing from the three velcro pieces as shown.

9. Firmly apply the bracket to the top weight stack with the bent tabs facing downward and flush against the left side of the weight as shown. NOTE: Verify the "Incremental Weight" (if applicable) does not interfere with the bracket.

10. Attention: Batteries should already be installed into the main unit and turned on before doing this step. Remove the protective backing from the main unit, install main unit so the battery door/ top cover opens towards the pull pin and firmly place it onto the bracket just under the second hole set and over the bent tabs. Verify the "Incremental Weight" (if applicable) does not interfere with the main unit. 

Note: Even though the unit is preloaded with Velcro tape, we recommend battery replacement by not taking the main unit off of the top plate and instead opening the battery door / top cover.

 

11. Confirm assembly of the main unit

Main Unit Installation Complete

 

Install Reflective Card

The main unit is mounted on the top plate of the weight stack, with a free line of sight to a reflective sticker that is attached to a flat surface above the main unit. The reflective sticker is mandatory to attach on a suitable area inside the machine with a free line of sight to the main unit. The optical sensor shall move together with the weight stack in a straight line against the reflective sticker. There must be a free field of view, approximately +/- 10 degrees from the sensor against the reflective sticker. The maximum distance between the main unit in its lowest position and the reflective card at the top is 160cm/63 inches. The reflective sticker that is delivered with the main unit must be used; no other reflective card is allowed.

1.  The reflective tape is placed directly above the main unit and applied to the underside of the upper crossbar between the machine's two upper placards. It is not visible unless looking up between the placards. Use the alcohol pad to clean the area where the reflector tape will be applied as shown. NOTE: Allow at least 4 minutes for alcohol to dry.

2. Looking in from the rear of the machine, measure according to the reflector tape table, column A from the end of the top crossbar and apply the reflector tape to the crossbar underside as shown.

3. Verify location placement.

 

Use the LF Assist App

 

1. Confirm cleaning of the top weight plate and tower where you placed the reflective card

2. Confirm placement of the reflective card

 

3. Confirm placement of main unit

 

4. Follow instructions in app to put main unit into pairing mode. Press Find

5. The application is now searching for the main unit and measuring its signals. 

 

6. Verify that the distance between the main unit and the reflective card is roughly as it says in the application. 

 

7. Press "Other"

 

 

8. Press Add Exercises to add an exercise or copy exercises to copy an already existing exercise from the gym site. Choose the machine exercise for the current machine by pressing a name. (Press the info button to see an instruction video of the exercise)

9. Repeat step 8 to add more machine exercises on the machine like the chest fly/rear delt, hip adduction/hip abduction assisted dip/chin or press done to continue.

 

10. Select the main weights by pressing the top weight stack. Choose the main weight stack amongst the list of weight stacks or create a new one by pressing the “+”-button. (If this is the first machine being installed on the gym site, the list will be empty)

If the main weight stack of the machine doesn’t exist in the list, create a new one following these steps: 
Enter the number of weights on the weight stack.
Add the first and second value of the weight stack.

A “smart-add” solution fills the rest of the list with values of the same delta weight as the last pair of weights. Confirm that the values are correct. If not, correct the values manually according to the weight stack from top to bottom. Press save.

If the machine has and incremental weight “extra weight”:
Select the extra weight by pressing the bottom weight stack. Choose the extra weight stack amongst the list of weight stacks or create a new one by pressing the “+”-button. (If this is the first machine being installed on the site, the list will be empty)

If the increment weight "extra weight" stack of the machine doesn’t exist in the list, create a new one following these steps:
Enter the number of stacks on the weight stack.
Add the first and second value of the weight stack.

A “smart-add” solution fills the rest of the list with values, in the same way as for the main unit stack. Confirm that all values are correct. A quick way to do this is to check to see if the bottom/heaviest number of the stack matches the bottom number on the app. If not, correct the values manually according to the weight stack from top to bottom. Press save.
