Removal and Installation of Take-up Roller

Warning ・ When loosening the grease cylinder check valve, loosen it a little at a time. ・ The pressure inside the cylinder is very high, so there is a danger of grease being expelled and the plug flying off. The check valve adjustment procedure should not be done in front of the check valve. ・ Do not get under the machine when the main unit is jacked up. ・ Make sure to place the main unit on wood planks or the like to prevent falling. ・ Align the shoe assembly feed location and stop the engine except when working.
