Safety notice
15)After finishing the work, stop the hoist at the
specified position and raise the hook to at
least 2 m above the floor. Do not leave the
sling installed to the hook.
8. Selecting wire ropes
1) Select adequate ropes depending on the
weight of parts to be hoisted, referring to the
table below.

9. Precautions
for
connecting hoses and tubes in an air condi-
tioner circuit
1) Disconnection
k
Although the refrigerant (refrigerant
gas: R134a) used on the machine's air
conditioner is less destructive to the
ozone layer for environmentally friend-
liness, it is not allowed to be released
into the atmosphere as is. Whenever
disconnecting the air conditioner gas
circuit, be sure to recover the refriger-
ant gas to reuse it.
a Ask a qualified person for collection and
charge of the refrigerant (R134a).
a Never release the refrigerant (R134a) to
the atmosphere.
k
If the refrigerant gas gets in your eyes
or contacts your skin, you may lose
your sight or your skin may be frozen.
Whenever recovering or adding refrig-
erant gas, you must put on safety
glasses,
safety
sleeved clothes.
The refrigerant gas must be recovered
and added by a qualified person.

2) Connection
1] When installing the air conditioner circuit
hoses and tubes, take care that dirt, dust,
water, etc. will not enter them.
2] When connecting the air conditioner
hoses and tubes, check that O-rings (1)
are fitted to their joints.
3] Check that O-ring (1) is free from flaw and
deterioration.
4] When connecting the refrigerant piping,
apply compressor oil for refrigerant
(R134a) (DENSO: ND-OIL8, VALEO
THERMAL
(equivalent to PAG46)) to its O-rings.
