Pre-exercise advice

Warm-up
Take warm-up exercise for 5 to 10 minutes before using this machine each time.
Breathing
When exercising, you can’t hold your breath, usually inhale with nose when intending to release actions, and exhale with mouth. Inhaling should be coordinated with exhaling. If breathing too fast, you should stop exercising immediately.
Frequency
After the exercise of the same parts of the muscles, this part should have 48 hours’ rest. That is to say, it only can be exercised every other day.
Load
Decide the training volume based on the training state of everyone’s physical fitness, and then exercise according to the progressive overload principle. At the first exercising stage, muscles soreness is normal and can be eliminated by keep exercising.
Diet
To protect digestive system, exercise should be taken one hour after a meal. Eating should be done at least half an hour after exercising. When exercising, drink less water, and especially avoid drinking much so as not to increase the burden of heart and kidney.
Stretching exercise
Whatever your running speed is, you’d better do stretch exercise first. Warn muscles are easier to stretch, so walk for 5 to 10 minutes to warn up. Next, stop to do stretching exercise for five times according to the following methods, 10 seconds or more for each leg, and do again after exercising.

Stretching downward
Slightly bend knees, and slowly bend the body down. Relax back and shoulders, touch the legs and toes as close as possible with hands, keep for 10~15 seconds and then relax. Repeat for three times. (see picture 1)
Hamstring stretching
Sit on a clean cushion, stretch one leg straight, bend the other leg inside to cling to the inner side of the straight leg, touch the legs and toes as close as possible with hand, keep for 10~15 seconds and then relax. Repeat for three times for each leg. (see picture 2)
Shank and heel tendon stretching
Stand with two hands on the wall or desk and one foot backward. Keep back-leg upright and its heel touching the ground, lean toward to the wall or desk, keep for 10~15 seconds and then relax. Repeat for three times for each leg. (see picture 3)
Leg muscles stretching
Put the right hand on the wall or desk, then stretch the left hand backward, hold the left ankle and pull it upward to the hip until you feel the front muscles of the upper leg is tense, pull for about 10~15 seconds and then relax. Repeat for three times for each leg. (see picture 4)
Sartorius (inner side muscles of leg) stretching
Sit down with leg bottom against each other and knees outward, hold feet with hands, pull toward to abdominal groove, keep for 10~15 seconds and then relax. Repeat for three times. (see picture 5).

Maintenance

Lubricating
The running belt must be lubricated with specially configured methyl silicone oil after used for a period of time.

Advice:
When use time a week is less than 3 hours, it should be lubricated once in five months.
When use time a week is between 4-7 hours, it should be lubricated once in two months.
When use time a week is more than 7 hours, it should be lubricated once in one month.
It can’t be over-lubricated. It is not the more lubricant, the better. Remember: proper lubricating is the important factor to increase the treadmill’s service time.

Lubricating methods
For the methods to examine whether it is needed lubricant, you only need catch up the running belt and touch the central part of the back of the belt with hand as nearly as possibly. If the belt is with silicon resin (a bit sense of dampness) inside, this means no lubricant is needed; if the running board is dry and you feel no silicon resin inside, this means lubricant is needed.

A. Steps for coating the running board with lubricant: (see the picture)
B. Stop the rotation of the running belt and fold the machine.
C. Pick up the belt on the back of the body frame: stretch the oil holder as nearly as possible into the moving place of the belt, coat the inner side of the belt with silicone oil and coat both sides of the belt with silicone resin, and then operate the treadmill at the speed of 1KM/H so as to evenly coat the silicone resin; and step on the belt from left to right for a few minutes, then the silicone resin will be completely absorbed by the belt.
Also you can add oil to the lubrication hole of rail directly. Same as the photo shows.

Running belt tension adjustment
All treadmill’s belts should be adjusted before leaving the factory and after the installation, however, after it is used for a period, looseness may occur. For example: when users are running, it may occur pause and slip, if which happens, adjust the belt and bolts synchronously from both the left and right side in a clockwise direction and with semicircle as the unit; if the running belt is too loose, it may occur slip between the belt and the roller when treading on the belt; but if too tight, it will be easy to increase the motor load and damage motor, running belt, roller, etc.

Running belt deviation adjustment
All treadmill’s belts should be adjusted before leaving the factory and after the installation, however, after it is used for a period, it may occur belt deviation, which is caused by the following reasons:

a) The main engine is not placed evenly.
b) The user’s feet are not on the center of running belt.

If the deviation phenomenon is caused by the uneven force of the user’s feet, no-load rotation for a few minutes can make it normal. For deviation phenomenon that can’t return to normal automatically, adjust step by step by using 6MM inner hexagon spanner with the machine and with quarter-circle as the unit. Running belt deviation is not covered in the warranty scope and is mainly maintained by users according to the instruction book. Deviation phenomenon will severely damage the running belt, so it should be found and corrected in time.

Driving belt adjustment
All the treadmill’s driving belts are adjusted before leaving the factory, but after using for a period, it may still occur slip, which is mainly adjusted by users. Adjustment steps (see the picture):

Clockwise rotate adjustment screw with spanner.
Adjustment scope is subject to no slip when loading.

Notice : Periodically clean the impurities in the belt groove and the belt wheel groove.

Treatment method of running belt slip or pause
First open the front motor cover, then open the treadmill, hold the hand grip with both hands, step on the belt hard with your feet, watch it is the conveyor belt of the motor that pauses or the running belt that pauses. If running belt pauses, adjust the running belt, while if conveyor belt of the motor pauses, adjust the motor.

Troubleshooting and Maintenance

Fault Code	Main reason	Solution
Treadmill not working	A No power	Plug in to get power
B.Safety key off	Put on safety key
C.Connection wire not work well	Check all connection wire
