First use
DANGER!
Connecting the Quadsaw to the reach arm is a very dangerous phase. Ensure you carry out the
entire operation in strict compliance with the instructions.
The Quadsaw features a hydraulic motor with
three hydraulic hoses, ¾” pressure, ½” return and ¼” case drain. This
allows the Quadsaw to be adapted to any reach arm or carrier frame with standardised fittings. Upon request quick
release fittings can be options. Upon the first installation, simply remove the machine from the packaging and set it up
correctly.
The installation, adjustment and testing of the Quadsaw involve hazardous operations. Carefully read all the
instructions described in this manual. If in doubt, contact the manufacturer directly. In any case, before commissioning
the Quadsaw, immediately after transport, check that the machine supplied is intact and complete. The Quadsaw can
be installed and subsequently removed from the reach arm/carrier frame according to the requirements of the user.
DANGER!
Spearhead cannot be held liable for damage to persons, animals or property, caused by non-
compliance with the safety and accident prevention regulations or operations which do not conform to the
information provided in the user and installation instructions.
3.2.1
Prior to installation and application to the tractor
Before installing the Quadsaw it is advisable to check the suitability, good condition and adjustment of the agricultural
tractor and reach arm/carrier frame on which it will be installed:
3.2.1.1. Begin by first checking the minimum mass required of the reach arm/carrier frame. They must match the
minimum characteristics stipulated by the manufacturer of the Quadsaw, which are indicated in this manual in
Section 1.4
“Machine general specification” paragraph;
3.2.1.2. Move the tractor to the place where the Quadsaw was deposited after being transported and stop it in a safe
and practical position for assembly to be performed on level ground;
3.2.1.3. If the reach arm and Quadsaw are intended to be fitte
d with a “standard” hitch aim to line up the bolt holes by
lowering the reach arm/carrier frame to line up the faces;
3.2.1.4.
For the optional “quick release” fitment aim to line up the faces with an intention to guide the mounting plate
under the Quadsaw hook.
WARNING!
Due to the danger of this operation, it must be performed by expert and responsible personnel. Do
not touch the Quadsaw and do not stop within the operating range of the reach arm.
3.2.2
Application to the tractor
WARNING!
Clean and clear the installation area from any obstruction before starting to work. The area must
be specifically closed off and personnel not assigned to the works must be made to move away. The available
means must be verified to be intact and suitable. The operator must also tighten all the bolts and fittings
properly, using suitable tools.
DANGER!
All the following assembly and installation operations must be carried out with the tractor engine
switched off.
The application of the Quadsaw to the reach arm/carrier frame must take place on flat ground.
The Manufacturer declines all responsibility for the breakage of the tractor or reach arm/carrier frame.
Proceed as follows for the coupling, see Figure 3.2:
For Standard Mounting
3.2.2.1 Use appropriate protective gloves align the reach arm mounting face to the Quadsaw with an aim at lining up
the bolt holes. Ensure the blade is mounted, so the direction of rotation of the saw goes down Figure 3.2
3.2.2.2 Switch the tractor off and engage the parking brake.
