safety goggles and protective gloves during work. Additionally, if you swallow grease or oil by
mistake, this may cause vomiting or diarrhea.

3. If grease with different characteristics is mixed with proper grease, this may cause the machine
performance to lower.

Cautions on handling batteries
1. Do not disassemble the battery or touch its inside. Otherwise, electrical shock may result.
2. Do not over-heat or apply a strong impact to the battery. Otherwise, fluid leakage, explosion, or
heat generation, etc. may result. Never use the battery, to which a strong impact has been applied,
such as dropping to the floor since its battery fluid may leak.
3. Only engineers who have the experience and knowledge about electrical work are allowed to
replace the battery.
4. The battery may discharge naturally. When purchasing a spare battery, do not store it for a long
period and prepare it 1 to 2 months before the scheduled replacement work. Additionally, when
storing the battery, avoid a place where the temperature increases and be sure to store it at room
temperature.

4.13 Handling heavy objects
This machine (including optional units) may require the operator to handle heavy objects during work. (For
example, magazine or cassette replacement) If you hold up a heavy object in an unnatural posture, this may
cause damage to your back. Additionally, if you fall a heavy object to your feet, this may cause serious
personal injury. Or, falling a heavy object may cause damage to the magazines or internal tray components.
►
Cautions on handling heavy objects
1. Be careful not to take an unnatural posture during work. In particular, be aware that you may take
an unnatural posture easily when holding up a heavy object from a low place. It is recommended to
hold up a heavy object by bending and stretching your knee instead of bending your waist or
prepare a cart with an appropriate height when necessary.
2. When handles are provided, such as magazine or cassette, hold the handle securely and perform
the work.
3. To prevent personal injury caused by heavy object dropping, be sure to wear safety shoes.
c
CAUTION
When heavy object handling standards are defined at the customer's factory, be sure to follow the standards during work.
