NOTE: When disconnecting a coupler located in a narrow
space that is difficult for your hand to enter, use a screwdriver
following the procedures as described below.
Using Screwdriver
A screwdriver with a tip thickness of less than 1 mm and a
tip width of approx. 5 mm is appropriate to this work.
Slightly push the hose toward the coupler approx. 2 mm.
While pushing the hose toward the coupler, insert a
screwdriver in the position as illustrated to the right. Twist
the screwdriver about 90º. After making the gap between
the adapter and the dust prevention cover more than
2 mm, pull the hose to disconnect the coupler.
3. Precautions for Re-using Coupler
Before connecting the coupler, be sure to check the
coupler surface for any adhered foreign matter. Clean to
remove the foreign matter if any. Adhered foreign matter
may cause oil leaks and/or disconnection of the coupler.
When a hose clamping is required, put a clamp 200 mm
away from the joint edge. If the hose is clamped as
illustrated to the right, the coupler joint may slide as oil
pressure changes, causing oil leaks due to the premature
inner parts wear.
Do not use the coupler as a foot step and do not handle
the coupler roughly. If the dust prevention cover is
broken, the coupler may become difficult to disconnect.
Do not paint on the joint surface. The body will be seized
with the dust prevention cover so that the coupler cannot
be disconnected.
