The blade rest shaft consists of blade rest and shaft. When installing, it’s
necessary to clean up the blade rest and shaft first. There should not be any
dust or sundries with the blade rest shaft. Otherwise, the blade rest and shaft
might not fit with each other or even turn into scrap. After cleaning, put the
blades on oil press. Then put the shaft into blade rest holes and keep the shaft
vertical. Spread some lubricant on the shaft to smooth pressing it into the blade
rest shaft when installing.

Put the blades stand vertically first as well as lay the shaft sleeve level on the
blade rest shaft. Next, put a sleeve which fits the inner hole over the shaft
sleeve and then pressing the shaft sleeve in by using the oil press or slightly
beating it into by using copper bar. After installing the shaft sleeve, put the
material fender onto the shaft sleeve: 3 holes on the material fender should be
aimed to the 3 M8 holes on blade rest; the 3 M8 holes should be filled with
screw locking agent. At last, tighten the two parts up with 3 countersunk
hexagon screws M8x16.
