Chapter 2. Safe Handling of the Finisher
This chapter describes the rules for safe handling of the finisher which must be strictly
observed by all maintenance personnel. Before conducting maintenance and inspec-
tion of the finisher, you must fully comprehend the following.
1. Before conducting maintenance or inspection, be sure to switch the power supply
OFF .
2. If it is absolutely necessary to work with the power turned ON, observe the follow-
ing:
3. Have one individual watch while the work is being performed so that that person
may switch OFF the power switch at anytime if necessary.
4. Never allow two individuals to work at the same time. It is very dangerous if a
drive part actuates suddenly.
(a) Never wear a ring, wristwatch, cuff-links, bracelet, metal fastener or any other
metallic objects.
(b) Be sure not to loosen or misuse screws. It is good practice to put a sheet of
paper under a portion where it is difficult to find small parts if dropped. Make it
a rule to replace screws back to their original place immediately after removal
of a part.
(c) Be particularly careful not to let a tool or a part drop into the finisher.
5. Whenever working on near a rotating part, stop the rotation and ascertain the
shape of it. The projection of a rotating part is very dangerous as it cannot be
seen when rotating. During work, pay attention to ties, sleeves, shirts and long
hair so that they may not be caught in the finisher. Always wear a working cap.
6. Before handling a movable part, make certain that it has completely stopped.
7. Wear eye protection whenever the following jobs are to be performed;
(a) To hammer the pins or rivet.
(b) To perform work using a hand drill.
(c) To mount or dismount a spring.
(d) To perform soldering or cutting wires.
(e) To clean parts.
8. Make sure that the power is OFF when replacing a PCB.
9. Care must be taken to store covers which are detached at a proper place to avoid
other people from tripping or stumbling, over them.
10. Do not leave tools in any unit, nor leave them on the floor. It is dangerous if they
are dropped into a unit and also it may cause other people to trip or slip on them
in another instance.
11. When you are going to move the finisher, first check to see that no personnel or
customers are around a dangerous position.
12. Carefully observe cautions itemized in this Maintenance Manual for your opera-
tions.
13. Be sure that nobody touches the finisher and carefully recheck if there is incorrect
wiring, incorrect connections, or tools remaining on the finisher before turning ON
the finisher.
14. Replace all the covers of the finisher back to their original position and make the
final checks without fail.
15. Before handing the finisher over to the customer, perform overall checking again.
