Sunny Health & Fitness SF E905 Elliptical Machine Assembly – Step By Step Guide
Before you start the Sunny SF-E905 assembling process, select the area where you are going to set up and operate your machine. The location must be on a hard, level surface.

Also be sure that the workout space you are utilizing has adequate height clearance, taking into consideration the height of the user and the maximum incline of the elliptical machine fully engaged.
STEP 1: Install the leg stabilizers
With your assistance’s help, place some of the packaging material under the rear of the frame.
If there are shipping supports attached to the rear of the Frame, remove the screws from the shipping supports, and discard the screws and the shipping supports.
Have the second person hold the Frame to prevent it from tipping while you complete this step. After you identify the rear leg stabilizer, attach it to the Frame with Carriage Bolts, Arc Washers and Domed Nuts.
Remove the packing materials from under the rear of the Frame.
Repeat this step with the front leg stabilizer to attach the front stabilizer to the frame.
STEP 2: Install the tension controller and the handlebar post
Have a second person hold the Handlebar post on the Frame. Connect the Lower Sensor Wire to the Upper Sensor Wire, and then connect Tension Hook with the Tension Cable.
Make sure the Tension Controller is set at resistance level 1 before you connect the Tension Cable. This will ensure the wires are at their longest reaching point.
Next, insert the Handlebar Post into the post of the Main Frame, and secure it in place with Allen Bolts, and Arc Washers which are pre-attached to the Main Section.
STEP 3: Install Pedal Support Tube and Swing Bar

Attach the Swing Bar to the long axle of the Handlebar Post with Hex Bolt and Flat Washer.
Secure the Pedal Support Tube to the Crank with Locking Bolt, Wave Washer, then put on Spring Washer and Nylon Nut to the end of Locking Bolt.
Make sure to turn 19L counter-clockwise to tighten, and 19R clockwise to tighten.
Do not try to install the Left Bolt on the Right Crank or vice versa. The Left Bolt is meant only for the Left Crank, same for the Right Bolt.
The Right and Left Locking Bolt must fully penetrate the nylon ring of the Nylon Nut inside the Pedal Arm Joint and the Crank. This will ensure the stability and durability of your elliptical.
In order to install the Locking Bolt properly, keep it perfectly straight as the bolt goes through the pedal arms and into the crankshaft.
If the Locking Bolt is connected to the crankshaft at an angle, permanent damage to both the bolt and the crank may occur.
Next, fasten the Swing Bar and the Pedal Support Tube tightly with Hex Bolt, Flat Washer, and Nylon Nut.
Ensure that ALL bolts and washers are in place and partially threaded in before completely tightening any of them.
STEP 4: Install the Pedals
Secure the Pedals to the Pedal Support Tube using Hex Bolt, Flat Washer and Nylon Nut.
STEP 5: Install the Armrest
Start off by attaching the Armrest onto the Handlebar Post using the Spring Washers and Hex Bolts which came pre-attached to the Handlebar Post.
Then pull the Pulse Sensor Wire through the small hole on the front of the Handlebar Post and pull them out of the top.
Finally, attach the Decorative Cover onto the Armrest.
STEP 6: Install the Handlebar
Secure the Handlebar on the Swing Bar with Carriage Bolt, Arc Washer and Domed Nut.
If the Handlebar rubs the Armrest during the workout, check if you assembled the correct parts to each side.
Check the label on parts, Left is marked with an ‘L’, and Right is marked with an ‘R’)
STEP 7: Install the Console

Connect the Pulse Sensor Wires and Upper Sensor Wire to the console.
To avoid damaging the wires, push the wires back into the Handlebar post before sliding the Meter on.
Align the slot of the Handlebar post to the bulge inside the Meter then slide it onto the Handlebar Post slowly.
After you finish with the assembling process. Make sure that all parts are properly tightened before you use the elliptical.
