How about the electric sewing machine to tighten the straps

The sewing machine should be maintained after a period of use, so as to prolong the use of the product. The following are available:

The adjustment of the tension of the transmission belt, after using it for a period of time, it is found that the speed slows down, and the tightness of the belt should be checked: the tightness of the transmission belt is indicated in the manual of the electric sewing machine, and the finger is pressed in the middle of the belt to make the force droop by 5 mm. When using two transmission belts, the installation of one belt with fast speed can be appropriately loosened.

Regular lubrication outside the motor bearing: the machine that is often used adds one or two drops of sewing machine oil to the small oil hole on the motor end cover every quarter, and it is not advisable to add more, after too much oil stains the commutator, there will be a smell and the speed will decrease.

Replacement of the transmission belt: The V-belt transmits power by friction on both sides, and the belt is worn after use. If you touch the bottom of the groove and cause slippage, if you increase the tension force, the speed will decrease, and the slow performance will be poor, so you should replace it with a new belt of the same specification.

The brush is a kind of wearing part, avoid oil when using: after a certain period of use, the wear should be checked, and when the length of the brush is worn off 2 3 (about 5 mm), it is not suitable for use. There are many brush grades and specifications, which are suitable for different occasions according to their respective characteristics, and the replacement brushes should be brushes of the same type and specification.

When replacing, unscrew the brush cap and remove the brushes. When installing old brushes, you should recognize the direction. Keep the brushes and commutators in good contact.

Keep it clean: the motor and governor should be kept clean, the fluff and other threads that appear during sewing may invade the electrical appliances and affect the use, so the accumulated dust should be removed regularly.

Maintenance must be carried out after the power supply is cut off: the electrical dismantling indicated in the manual should be carried out under the guidance of specialized experienced personnel to avoid unnecessary failures.

The lid should be closed when the sewing machine is not in use and stored in a dry, chemical-free environment.
