the operator is able to follow safety regulations and the
procedures of maintenance activities..
1RWH Read carefully and understand the following
information with concerns to safe operation practices
before operating this equipment.
,PSRUWDQW
The owner and the operator are responsible for
following all safety regulations and that the machine
is safely equipped.
,PSRUWDQW

each shift.
,PSRUWDQW
Inspect and lubricate the unit atthe beginning of each
shift. Tighten all fasteners regularly.
,PSRUWDQW
All service and repairs should be carried out by
qualified personnel or an authorized repair shop with
suitable tools and lifting devices.
,PSRUWDQW
When working on the saw chain always ensure the
engine is shut off and wear safety gloves to prevent
injuries. Remove the saw chain when making any
adjustments or servicing the saw unit.
,PSRUWDQW
Never adjust any hydraulic pressures without using a
pressure gauge.
,PSRUWDQW
Consider the environment. Plug all connections to
avoid unnecessary spill of oil.
:DUQLQJ
The hydraulic input of the equipment must not
exceed the recommended maximum rating as
structural failure could occur, resulting in injury and
damaged equipment.
:DUQLQJ
Before performing any maintenance or service work,
lower the attachment to the ground and shut off the
engine. Turn off any master shut-offs and do not
allow personnel in the cab.
:DUQLQJ
Keep all windows and doors securly closed when
operating.
:DUQLQJ
Never touch or stand close to the pressurized
cylinders and hydraulic hoses.
:DUQLQJ
The attachment has sharp edges. Use proper
wrenches and protective gloves when working on the
attachment.
Fig. 1 The operating area of the saw attachment and the
recommended safety distance
90 meters/300 feet
:DUQLQJ
When operating this equipment ensure all other
personnel remain at least 300 feet clear of the
machine. Turn the machine off immediately if
anyone enters this safety zone.
:DUQLQJ
Training or demonstration of this equipment should
be performed from an operator´s cab approved by
national regulations. Observers should always
remain at least 300 feet away.

The 6XSHU6DZ6 grapple saw is generally mounted
together with SuperGrip or SuperGrip TL grapples on log

used for timber, in whole-tree, tree length, and waste wood
systems.

Together with its range of accessories, Hultdins patented
6XSHU&XW saw unit is a comprehensive
alternative for all applications with demands on
functionality, reliability, service-friendliness, economy
and the environment.
6XSHU&XW is a complete unit with
integrated feed cylinder, well protected from external
damage. It has been designed for use with hydraulic
motors of the type VOAC F11 - 10 or, alternatively, F11 -
19. The saw motor bracket is assembled in ballbearings in
the saw unit so that the hydraulic motor is stationary when
the saw is fed out. The saw bar is returned either
pneumatically by an accumulator or hydraulically with oil.
In its standard version, the
6XSHU&XW is
equipped with automatic hydraulic chain tensioning and
cam controlled mechanical lubrication pump that
distributes lubricant to the chain during the complete
sawing operation.
The mechanical lubrication pump delivers a maximum
volume of 6 ml and the process can easily be adapted to
specific lubricating requirements with a number of
different cams. All the lubrication oils found on the market
can be used.
All this in combination gives good saw bar, chain and oil
economy.
With the accessories that are available for the
6XSHU&XW

, you can easily design an integrated
unit consisting of the saw unit, cam, saw motor, saw motor
manifold, pressure regulating valve kit and drive sprocket
kits.
Air and lubrication oil tanks are available as extra
accessories and the
6XSHU&XW can be
equipped with a saw home detector sensor and a cut
control kit as options. The cut control kit is used in
combination with a computerized bucking device and
limits the angle to which the saw bar is fed out in
relationship to the diameter of the tree.

When the feed line (P) is pressurised from the saw
function, a reduced pressure (2.0-2.5 MPa/290-360 PSI )
from the pressure regulating valve (3) acts on the pistons
(1) and (2). The piston (1) keeps the chain tight while the
pistons (2) hold the bar holder to the tensioning device
when sawing is in process. The spring (4) delivers
auxiliary tension during the first sawing operation after
replacing the chain. The check valve (5) prevents the chain
from becoming slack from external obstructions e.g.
