STEP 2:

Lift up the Left Upright Tube (No. A04) upwards. Attach the Left Upright Tube (No. A04) to the Base Frame (No. A01), using 2 Bolts (No. E12) and 2 Washers (No. E25) on the side, and 1 Bolt (No. E12) and 1 Washer (No. E25) on the front. Tighten and secure using Allen Wrench (No. B04).

Repeat the step above to assemble the Right Upright Tube (No. A05) to the Base Frame (No. A01).

Note: During assembly, support the Left & Right Upright Tubes (No. A04 & No. A05) with your hand to prevent them from falling down.

STEP 3:

Connect the Upper Signal Wire (No. D03) to the Lower Signal Wire (No. D04).

Attach the Console (No. D01) to the Left & Right Upright Tubes (No. A04 & No. A05) with 2 Bolts (No. E07), 4 Bolts (No. E12) and 6 Washers (No. E25). Tighten using Allen Wrench (No. B04).

STEP 4:

Cut the Packing Belt (No. F).

STEP 5:

Loosen the Bolt (No. E12) and Plastic Pad (No. C19) in the Base Frame (No. A01) by using Allen Wrench (No. B04).

STEP 6:

See Page 13 for instructions on how to fold the treadmill.

Fold the treadmill and loosen the Bolt (No. E12) and Plastic Pad (No. C19) in Main Frame (No. A02) by using Allen Wrench (No. B04) then remove Safety Block (No. B09).

Please keep Plastic Pad (No. C19), Bolt (No. E12) and Safety Block (No. B09) for spare parts after dismantling the safety block.

STEP 7:

The assembly is now complete! You may now insert the Safety Key (No. D06) into the magnetic area on the Console (No. D01).

❗ IMPORTANT NOTE! You will need to lubricate your treadmill before the first use. See Page 12.

MAINTENANCE & CARE

General cleaning will help prolong the life and performance of your treadmill. Keep the unit clean and maintained by dusting the components on a regular basis. Clean both sides of the Running Belt (No. C11) to prevent dust from accumulating underneath. Keep your running shoes clean so that dirt from your shoes does not wear the Running Board (No. D09) and Running Belt (No. C11). Clean the surface of the Running Belt (No. C11) with a clean damp cloth.

To better maintain the treadmill and prolong its life, it is suggested that the machine be powered off for 10 minutes every 2 hours and fully powered off whenever not in use.

CENTERING THE RUNNING BELT:

Place the treadmill on level ground and set it at 3-5mph to check if the Running Belt (No. C11) drifts from the center.

If the Running Belt (No. C11) drifts to the right, turn the adjusting bolt on the right side 1¼ turn clockwise, then turn the left adjusting bolt ¼ turn counter-clockwise. If the Running Belt (No. C11) does not move, repeat this step until it centers. Refer to Figure A.

If the Running Belt (No. C11) drifts to the left, turn the adjusting bolts on the left side 1¼ turn clockwise, then turn the right adjusting bolt ¼ turn counter-clockwise. If the Running Belt (No. C11) does not move, repeat this step until it centers. Refer to Figure B.

Over time the Running Belt (No. C11) will loosen. To tighten the Running Belt (No. C11) turn the Left & Right side adjusting bolts one full turn clockwise, check the tension of the Running Belt (No. C11). Continue this process until Running Belt (No. C11) is at the correct tension. Make sure to adjust both sides equally to ensure correct belt alignment. Refer to Figure C.

Diagram A shows adjusting the belt to the right by turning clockwise on the right and counter-clockwise on the left.

Diagram B shows adjusting the belt to the left by turning clockwise on the left and counter-clockwise on the right.

Diagram C shows tightening the belt by turning both left and right adjusting bolts clockwise.

LUBRICATING THE TREADMILL

❗ IMPORTANT NOTE: You will need to lubricate your treadmill before the first use.

RUNNING BELT & TREADMILL LUBRICANT:

Lubricating the Running Board (No. D09) and Running Belt (No. C11) is essential as the friction affects the lifespan and operation of the treadmill. Inspect the Running Board (No. D09) and Running Belt (No. C11) regularly. If you find any wear on the Running Board (No. D09), please contact us at: support@sunnyhealthfitness.com.

❗ WARNING: Always unplug the treadmill from the electrical outlet before cleaning, lubricating or repairing the unit.

HOW TO LUBRICATE:

1. Raise the Running Belt (No. C11) up on one side and apply lubricant to the Running Board (No. D09). Use a rag to thoroughly wipe the lubricant over the Running Board (No. D09). Repeat this process for the other side.
2. The moving parts should turn freely and quietly. Abnormal moving parts will affect the safety of the equipment. Inspect and tighten bolts regularly.
3. To better maintain the treadmill and prolong its lifespan, it is suggested that maintenance be done on a regular basis.
4. DO NOT LOOSEN OR MAKE ANY ADJUSTMENT TO THE RUNNING BELT WHILE APPLYING LUBRICANT. A loose Running Belt (No. C11) will result in the runner sliding off during use, while too tight of a Running Belt (No. C11) will negatively affect the motor's performance and create more friction between the roller and Running Belt (No. C11). The most suitable tightness for the Running Belt (No. C11) is when it is pulled out 50-75mm from the Running Board (No. D09).

Diagram shows the Running Belt above the Running Board, illustrating the space for lubrication.

FOLDING INSTRUCTIONS

FOLDING:

Place your hand at position "D" and lift the Main Frame (No. A02) up until the Air Pressure Cylinder (No. B06) "C" locks into the tube. You will hear a clicking sound when it locks.

UNFOLDING:

Before lowering the Main Frame (No. A02), ensure that the space directly underneath is clear of any objects and the power is turned off.

Grasp the Main Frame (No. A02) at position "D" with one hand. Next, using your foot, lightly kick the Air Pressure Cylinder (No. B06) "C" and press down on the Main Frame (No. A02). Once the Main Frame (No. A02) has been pushed down, it will automatically continue to steadily lower itself until it reaches the ground.

HOW TO MOVE THE TREADMILL

Before attempting to move the treadmill, please make sure that it has been properly folded. Unplug the Power Wire (No. D14).

To tilt, start by placing one hand at position "D" to support the top end of the treadmill. Next, place one foot at position "E" to hold the bottom end of the treadmill steady. With your foot at "E", slowly tilt the top of the treadmill downward towards the ground. Once the Main Frame (No. A02) reaches a low enough point, the Moving wheels (No. C18) of the treadmill will touch the ground.

To transport, hold the treadmill from position "D" and tilt until the Moving wheels (No. C18) "E" are able to move on the ground.

Diagram shows a person tilting the folded treadmill using hand support at 'D' and foot pressure at 'E' to engage the moving wheels (C18).

IMPORTANT ELECTRICAL INFORMATION

❗ WARNING: This treadmill requires a power source of 10 amps (100-120V) in order to properly operate.

Ensure that the product is connected to an outlet with the same configuration as the plug. Do not use an adaptor for this product.

This product is for use on a nominal 100-120V circuit and has a grounding plug that looks like the plug illustrated in sketch A. Make sure that the product is connected to an outlet having the same configuration as the plug. No adapter should be used with this product.

⚠️ DANGER: Improper connection of the equipment can result in risk of electric shock. Check with a qualified electrician or serviceman if you are unsure whether the product has been properly grounded. Do not modify the plug provided with the product. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.

WARNING!

1. NEVER use a ground fault circuit interrupt (GFCI) wall outlet with this treadmill. Route the power cord away from any moving parts of the treadmill including the elevation mechanism and transport wheels.
2. NEVER operate the treadmill using a generator or UPS power supply.
