Reversal or replacement of fixed jaw plate
k
This machine uses cover assembly (1) with
springs built into the fixed jaw plate wedge
portion and swing jaw plate wedge portion.
If bolts (2) of the front face of the cover are
removed during disassembly, there is dan-
ger that the internal parts will fly out and
cause injury.
k
After removing the fixed jaw plate, com-
pletely remove soils, sand, etc. from the
fixed jaw fitting surfaces (front frame and
mount stopper upper surface). Unless
removed completely, they may cause a
backlash on the fixed jaw plate.
If the clearance is not even on the right and
left sides, there will be a slippage from the
swing jaw plate tip, which likely leads to
premature wear or partial wear on the jaw
plates.
1. Remove the cheek plate. For details, see
"Replacement of cheek plate".
2. Remove the fixed jaw wedge bolt spring cover
assembly, fixed jaw wedge bolt, and fixed jaw
wedge block.
