Adjustment of the backlash between the Gearbox and the Arm rail.
The backlash appears after the machine has been used for a period of time. It is necessary to
adjust the tightness between the Arm rail and crankshaft bearing.
a. Remove the side plate as the above figure 1.
b. Release the bolts as the above figure 2. Using socket wrench, insert it into the holes as
shown in the above figure 3 and rotate them. Apply the tightness as the hand wheel of the
Gearbox can be turned easily but not too easily. Apply the same to the counter side.
c. Release the bolts as shown in the right figure 4.
d. Using socket wrench, insert it into the holes as shown in the above figure 5 and rotate
them. Apply the tightness as the hand wheel of the Gearbox can be turned easily but not
too easily. Apply the same to the counter side.
e. Screw up the side plate of the above figure 1.
