Transport-------------------------------------------------------------------------
Take care of the following points for transporting the Ring Blow.
Caution
1. Take full care of fall and tumbling down during transportation. An
INJURY
is feared.
2. Lift up the Ring Blow equipped with a hanger bolt always after getting rid of
loosening of the hanger bolt. But after mounting the Ring Blow on a machine, do not
lift up the entire machine using the mounted hanger bolt.
Verify the mass of motor based in the nameplate, package box, outline drawing,
catalog or the like before lifting it and do not lift any more mass than the rated load of
lifting tool. The gravity center of the Ring Blow is located at motor side, therefore, the
Ring Blow inclines to one side during lift-up.
Exert tension gradually on the wire and do not lift up suddenly.
This lift-up work may only be executed by the qualified workers. Do not stay under
the Ring Blow during the lifting work.
An
INJURY
or
FIRE
caused by
FALL
or
TUMBLING DOWN
is feared for all of these
cases .
3. Ambient temperature should be kept –20
℃～ +60 ℃ during transportation.

Safekeeping---------------------------------------------------------------------
Take care of following points for safekeeping the Ring Blow or suspending its operation for a long
period.
1. For safekeeping in the packed.
Keep the Ring Blow in an indoor dry place (Ambient temperature: -20 ℃ ~+50 ℃ ). Do not keep it on
such a place, as is exposed to water or dust, or with vibration, or place it on a bare ground
directly.
2. For keeping it in the installed condition.
(a) Cover the entire Ring Blow with a sheet for protecting it from invasion of moisture foreign
materials.
(b) Keep the Ring Blow with its hanger bolt mounted. If it is kept with the hanger bolt dismounted,
water may sometimes invade into through the screw hole.
(c) Run the Ring Blow for some minutes keeping it and every 3 months, for protecting the bearings
from rusting.
(d) If the operation of Ring Blow is suspended for a long period, measure the insulation resistance
of its winding every 6 months and verify that it is kept at higher than 1 M Ω . If the resistance is
not higher then 1 M Ω at normal temperature, such measures are required as to dry the winding.
(e) Keep the Ring Blow in an indoor dry place (Ambient temperature: -20
℃
~+50
℃
).
