The gap is suitable for passing two sheets of printing paper and it can ensure that there is no friction between fixed blades. After adjustment, tighten the tightening bolts of each moving blade and fixed blade (if necessary, increase the tightening degree by increasing the length of the spanner handle). After that, lock the upper case and confirm that it is firm and reliable. 5. Before the motor is installed and the belt is attached, conduct electricity for a short time, check and confirm that the rotation direction of the motor (drive wheel) is the same as the specified knife wheel rotation (the mower is prohibited from running in reverse), and then hang the belt.

During the operation, it is forbidden to remove the belt protection cover and straw bucket. It is forbidden to make and replace the feeding grass bucket whose safety protection size is less than 55 cm, and it is forbidden to open the upper casing. 2. Individuals who do not have mastery of mower safety rules are not allowed to work alone. 3.
