Operating instructions
Tilt adapter (option)
The hydraulic tilt adapter mounts
between the attachment and the
attachment coupling plate. It allows
the driver to tilt the attachment
sideways to both directions from
the driver’s seat. Tilt adapter is
intended mainly for non-hydraulic
attachments, but with the optional double acting extra
auxiliary hydraulics outlet in the front (A35477) it is possible
to mount a hydraulically operated attachment (e.g. a 4 in 1
bucket) at the same time. Tilt adapter is operated with the
auxiliary hydraulics control lever (no. 7, page 15).
Drive release valve
The switch no. 16, LOCK, controls
a valve, which is used to divert the
oil flow between left and right side
hydraulic motors, and this affects
the pulling force.
LOCK OFF: In this mode, the
hydraulic oil flows in series from motor to motor. The
wheels will roll more freely and the loader leaves less tire
marks on soft surfaces.
LOCK ON: In this mode the hydraulic oil flows in parallel
between the hydraulic motors in each side, similar to a
differential lock in operation. This improves the towing
capability of the loader.
Anti slip valve (option)
The valve positively diverts oil flow
between the right and left side
hydraulic motors and improves
traction on slippery and uneven
surfaces. It is engaged by pressing
continuously on the switch on the
joystick. As soon as the switch is
released, anti slip valve is released.
The function of the anti slip valve depends also on the
position of the drive circuit release switch no. 15:
LOCK ON : Anti slip valve diverts oil flow between all
four hydraulic motors - all four wheels have best possible
traction. Use sufficient engine revs and press properly on
the drive pedal.
LOCK OFF: Drive circuit released – anti slip valve diverts
the oil flow between the front left and right hydraulic
motor only, not the rear hydraulic motors.
Extra auxiliary hydraulics outlets, front
and rear (option)
In addition to the standard auxiliary hydraulics outlet,
the loader can be equipped with a double acting extra
outlet. The extra hydraulic outlet can be fitted either to
the front of the loader or to the rear, and the couplers
are conventional type quick couplers. The installed extra
outlet is controlled with the lever no. 9 (see page 15).
The loader can be equipped with either the rear hydraulics
outlet or with the extra front outlet – but not with both.
1. Extra auxiliary hydraulics
in the front
• Quick couplers are located
under the multi connector
2. Quick couplers in the rear
• Quick couplers are
located on top of the
radiator.
Double acting outlet
Warning beacon (option)
The beacon can be removed
quickly by unturning its retaining
screw and then by pulling the
beacon out. Place the protective
seal on the beacon stand to prevent
water entering and damaging the
connectors. Handle beacon with
care. The beacon is sealed and
its inner components cannot be
replaced or repaired by user.
Beacon includes high-voltage components.
Do not use or repair damaged beacon,
replace with new one.
Light bar (option)
Flashing lights on the light bar, only
available on DLX cab.
