ADJUSTMENTS GUIDE
#67 S6
#67 S6
The lowest point of the running belt
must not touch the ground.
ADJUSTING THE RUNNING BELT
When you use a treadmill, the pressure on the running
belt is not balanced due to the different forces used by
the two feet during running, which causes the running
belt to deviate from the center. This deviation is
normal, and you need to bring the running belt back to
the center. Observe which side the running belt is
skewed while running.
If it is biased to the left, use the Allen Wrench (No.
67) to turn the left screw clockwise or turn the right
screw 1/4 counterclockwise;
If it is biased to the right, use the Allen Wrench (No.
67) to turn the right screw clockwise or turn the left
screw 1/4 counterclockwise;
If the running belt is still not in the middle, repeat the
above movements until it is adjusted to the middle.
After the adjustment, pay attention to whether the
lowest point of the running belt touches the ground. If
so, adjust both sides of the running belt clockwise at
the same time until can’t reach the ground.
MOVING THE TREADMILL
When moving the machine, grab the handrail with both
hands and lift the machine, then move it.
#27
ADJUSTING THE BALANCE
When the uneven ground causes the machine to tilt,
you can adjust the rear 2 Foot Pads (No. 27) to keep
the machine stable.

MAINTENANCE INSTRUCTIONS
This is general information for daily, monthly maintenance to be performed on your treadmill.
MONTHLY MAINTENANCE
Check all hardware is solid, such as: column, table frame, handrail;
Check the running belt for signs of wear;
Remove foreign matter accumulated on the running belt.
DAILY MAINTENANCE
After each workout, wipe all areas: running platform, handrails, console. Pay special attention
to running with protection.
Sweat is highly corrosive and may cause problems that need to be
replaced later.
All treadmills should be adjusted before leaving the factory and after installation, but after a
period of use, it may also run off. The reasons causing the running belt deviation phenomenon
are:
The host is not stable;
The user's feet are not in the center of the running belt when exercising;
The user's two feet are not using the same force. It artificially causes a runoff. One foot pedals
the empty belt for a few minutes to return to normal. For a runaway that cannot be
automatically restored, apply the Allen Wrench (No. 67) in the random belt # 64 S6 to
gradually adjust at 90° one grille.
