PART4. MAINTENANCE AND TROUBLESHOOTING
4-1 Safety warning on maintenance
You must turn off the main power supply.
The maintenance staff should wear suitable footwear whilst carrying out maintenance work.
4-2 Regularly maintenance and cleaning
Areas that require cleaning: sliding plate, left cutter, right cutter and middle cutter.
Sliding plate: (Refer to FIG 3-
4
). Between the sliding plate, the left guide rail and right guide
rail should fit exactly and the front movement of the sliding plate must be smooth. Therefore
this position especially, needs to be cleaned and maintained. The cleaning procedure is
summarized as follows:
A. Remove the tension spring below the sliding plate.
B. Move the sliding plate backward and take it out.
C. Clean the grooves of the sliding plate and left and right guide rail.
D. Install the sliding plate between the left and right guide rail and pull the spring.
E. Move the sliding plate forward and backward, check whether it moves smoothly. If it is
necessary to adjust and the right guide rail cannot be adjusted, just adjusting the left
guide rail will be ok.
F. Apply a little cart oil or light lubricant to the gap between the sliding plate and left and
right guide rail.
G. If the sliding plate can move freely, but it cannot return back to its position, check
whether the tensioning spring has worn out. If so, change it or cut it so that it is shorter.
Regarding the left middle and right cutters, all of them must move up and down smoothly at
the chamber base, or the machine cannot strap normally. Therefore cleaning and
maintenance is very important. The method is as following: (refer to FIG 3-
5
).
A. Remove the tension spring on the middle and right cutters.
B. Move the upper sliding plate backward and take out the middle cutter first and then
remove the right cutter.
C. Clean the middle and right cutter and the machine chamber base.
D. Install right cutter first, and install middle cutter and spring after.
E. Apply some light lubricant oil around all of the cutters.
F. If the machine is running for a long time, and the middle and right cutters cannot cut off
the strap, then adjust the middle cutter closer to the right cutter a little. You must make
sure that the middle cutter can move up and down smoothly; or change the cutter head
of the middle cutter
