Operating The Auxiliary Port - Kubota U27-4 Operating Instructions Manual

Operation

Operating the auxiliary port

The auxiliary port serves for operating attachments.
Only implements approved by KUBOTA may be used. The implements must be operated in accord-
STOP
ance with the operating instructions supplied with them.
With the use of a breaker or another attachment for demolition work, where material (e.g. asphalt) is
removed and can uncontrollably sputter away, personal protective equipment is absolutely to be
STOP
worn (safety shoes, safety helmet, eye protection, ear protection and if necessary facial mask). The
use of a gravel guard (front protective grid) is recommended. For excavation work with a cab, the
front window must be closed, in addition. For demolition (according to EN 474-1, Annex G), e.g. tear-
ing down walls, the corresponding protective equipment is required (e.g. gravel guard).
The performance data for the auxiliary port can be found in the "Specifications" section (page 38).
Make sure that, before carrying out the activities in the auxiliary port connectors, the pressure relief
of the hydraulic system (page 87) has been carried out. Depending on the operation setting, the re-
STOP
turn change valve has to be set to the appropriate position (page 86).
The auxiliary ports may only be activated when an implement is attached.
If the auxiliary port has not been used for a longer time, dirt particles could have accumulated at the
connectors of the conduits. Before installing the implement, drain approx. 0.1 l of hydraulic oil at each
port.
Catch the drained hydraulic oil in a container and discard it in accordance with the valid environmen-
tal regulations.
Start the engine (page 70) and keep it at idle speed until the operating temperature has been reached.

The auxiliary port pedal (1) can be protected against
unintentional operating by turning the locking flap (2).
If the auxiliary port pedal is not used, the locking flap
must be folded in.
When operating the right pedal part (figure/ ) there is an oil

flow at the connector B (figure below).
When operating the left pedal part (figure/ ) there is an oil flow

at the connector A (figure below).
