Fix the mounting screws to the gear rack.
Put the gear rack on the output gear of the main machine; make the rack engage with the output
gear then weld the mounting screws to the gate (each screw marks with a solder joints in
advance).
Manually move the gate (gate should be moved smoothly after machine unlocked) to check
whether there is a fit clearance between gear rack and output gear, as shown in Figure 7.
Weld all the mounting screws to the gate firmly.
Make sure that all racks are on the same straight line.
Pull the gate after gear rack installed, make sure the entire trip is flexible without any stuck.
