FISHER
HYDRAULIC FRONT-LOADER EXTENSION ARM
OPERATOR'S MANUAL
After having mounted the carrier, connect hydraulic hoses (
A
) for side shift and tooling rotation
supply and hoses (
B
) for work head supply (PT circular saw, PG branch grinder) (
). Remember to
adjust oil flow rate [L/min] to work head's demand
–
see Tab. 1.
WARNING!
If FISHER is aggregated with PT circular saw, the motor of which has no third oil
separation pipe, then the return hose (B - female connector) must be connected
to a connector on a vehicle with pressure-less return line. Otherwise hydraulic
motor can be damaged.
If the vehicle has no hydraulic connector with pressure-less return line, refer to
the instruction manual, or consult the vehicle's manufacturer where pressure-
less return line can be connected to the tank.
Depending on the type of vehicle, with which the carrier is aggregated, it is allowable to replace
connectors or extend hydraulic hoses on the user's own. If the oil flow rate is not adequate, SaMASZ
offers ZH hydraulic power pack to be mounted on the rear 3-point linkage, Cat. II with maximum flow of
130L/min
–
pressure 200bar.
WARNING!
Extending or using too thin hydraulic hoses for work head supply can lead to
overheating the pack, improper operation of the tooling attached or its damage.
Connect 3-pin controller plug (
C
) to corresponding socket on the machine, and lighter outlet (
D
)
to 12V cigarette outlet.
WARNING!
When connecting hydraulic hoses and electric cables to front loader's arms, in
machine rotation points, provide and leave some allowance, so that during the
operation they are not damaged.
5.2.
Attaching work head to the carrier
The Fisher carrier enables aggregation of the following work heads: PG 150, PG 200, PT3-190, PT4-
250. To attach a work head to the carrier:
❑
position the vehicle and the carrier set, so that the holder with mounting plate (Fig. 2,
item 6
)
overlaps the head's plate;
❑
using six M14 bolt connections (
B
) joint the two plates together. Tighten the bolts with torque
corresponding to their property classes (
). Central M30 bolt connection (
C
) is not required,
howev
er it facilitates the head rotation by 180°, if needed;
❑
connect hydraulic connectors (
D
) and secure the hoses by clipping them with chain (
E
) (
