2. Check that the load is stable, and then
remove the sling.
3. Remove kinks and dirt from the wire ropes
and chains used for the sling work, and put
them in the specified place.
Precautions for using mobile crane
a Read the Operation and Maintenance Manual of
the crane carefully in advance and operate the
crane safely.
Precautions for using overhead traveling crane
k
The hoist or crane must be used to sling the
components weighing 25 kg or heavier. A
part weighing 25 kg or heavier in "disassem-
bly and assembly" section is indicated with
4
the symbol of
.
Before starting work, check the wire ropes,
q
brake, clutch, controller, rails, over winding pre-
vention device, ground fault circuit interrupter for
electric shock prevention, crane collision pre-
vention device, and energizing warning lamp,
and check the following safety items.
Observe the signals for sling work.
q
Operate the hoist at a safe place.
q
Be sure to check the directions of the direction
q
indication plate (north, south, east and west) and
the operating button.
Do not sling a load at an angle. Do not move the
q
crane while the slung load is swinging.
Do not raise or lower a load while the crane is
q
moving longitudinally or laterally.
Do not drag a sling.
q
When lifting up a load, stop it just after it leaves
q
the ground and check safety, and then lift it up.
Consider the travel route in advance and lift up a
q
load to a safe height.
Place the control switch in a position where it will
q
not be an obstacle to work and passage.
After operating the hoist, do not swing the control
q
switch.
Remember the position of the main switch so
q
that you can turn off the power immediately in an
emergency.
Shut down the main switch when the hoist stops
q
because of a blackout. When turning on a switch
which is turned OFF by the ground fault circuit in-
terrupter for electric shock prevention, check
that the devices related to that switch are not in
operating condition.
If you find an obstacle around the hoist, stop the
q
operation.
After finishing the work, stop the hoist at the
q
specified position and raise the hook to at least
2 meters above the floor. Do not leave the sling
attached to the hook.

Precautions for disconnecting and connecting
hoses and tubes in air conditioner circuit
Disconnection
k
When replacing the air conditioner unit, air
conditioner compressor, condenser or re-
ceiver drier, etc., collect the refrigerant (air
conditioner gas: R134a) from the air condi-
tioner circuit before disconnecting the air
conditioner hoses.
a Ask a qualified person for collecting, adding and
filling operations of the refrigerant (air condition-
er gas: R134a). (Only registered persons can
work.)
a Never release the refrigerant (air conditioner
gas: R134a) to the atmosphere.
k
If refrigerant gas (air conditioner gas: R134a)
gets in your eyes, you may lose your sight.
And if it touches your skin, you may suffer
from frostbite. Put on protective eyeglasses,
gloves and working clothes with long
sleeves while collecting the refrigerant or fill-
ing the air conditioner circuit with the refrig-
erant.
When loosening the nuts fixing air conditioner
q
hoses and tubes, be sure to use 2 wrenches; use
one wrench to fix and use the other one to loos-
en the nut.
