NOTE TO CUSTOMER / OWNER
Please ensure that the above section has been completed and signed by the selling dealer to
verify that your machine has been registered with Spearhead Machinery Limited.
IMPORTANT: During the initial ‘bedding in’ period of a new machine it is the customer’s
responsibility to regularly inspect all nuts, bolts and hose connections for tightness and re-
tighten if required. New hydraulic connections occasionally weep small amounts of oil as the
seals and joints settle in –where this occurs it can be cured by re-tightening the connection –
refer to torque settings chart below. The tasks stated above should be performed on an hourly
basis during the first day of work and at least daily thereafter as part of the machines general
maintenance procedure.

GENERAL INFORMATION
Read this manual before fitting or operating the machine or accessory. Whenever any
doubt exists contact your local dealer or the Spearhead Machinery Service
Department for assistance.
Only use ‘Genuine Spearhead Parts’ on Spearhead Machinery and equipment.
DEFINITIONS: The following definitions apply throughout this manual;
DANGER: Alerts to a hazardous situation which will result in death or
serious injury if not observed carefully.
WARNING: Alerts to a hazardous situation which will result in death
or serious injury if not observed carefully.
CAUTION: Alerts to a hazardous situation which could result in
damage to the machine and/equipment if not observed correctly.

VEHICLE/TRACTOR PREPARATION
We recommend vehicles are fitted with cabs
using ‘safety glass’ windows and protective
guarding when used with our machines. Fit an
Operator Guard such as Spearheads’ available
guard kit (part number OPT0603) and using the
hooks provided fit it to the vehicle. Shape the
mesh to cover all vulnerable areas. The driver
must be looking through mesh and/or
polycarbonate glazing when viewing the
complete working machine in any working
position –unless the vehicle/cab manufacturer can demonstrate that the penetration
resistance is equivalent to, or higher than, that provided by mesh/polycarbonate
glazing. If the tractor has a roll bar only, a frame must be made to carry both mesh and
polycarbonate glazing. The operator should also use personal protection equipment
(PPE) to reduce the risk of serious injury such as; eye protection (mesh visor to
EN1731 or safety glasses to EN166), hearing protection to EN352, safety helmet
EN297, gloves and high visibility clothing.
Vehicle Ballast
It is imperative when attaching ‘third-party’ equipment to a vehicle that the maximum
possible stability can be accomplished by the utilisation of ‘ballast’ in order to counter-
balance the additional equipment added. Quadsaw Branch Cutters have been tested
on the following reach arm systems: Spearhead Twiga MID, PRO & FLEX with tractors
from 4400kg, wheelbase of 250 cm and a track width of 200 cm measured from/to the
outer edge of the tyre till tractors of 5500kg, wheelbase of 280cm and a track width of
250cm measured from/to the outer edge of the tyre. Because there are different types
of tractor structures and differences in weight distribution you must view this as a
“guideline”. Is it possible, then choose wide tyres as possible to increase the stability
of the vehicle.
Front Weights
May be required for rear mounted machines to place 15% of total outfit weight on the
front axle for stable transport on the road and to reduce ‘crabbing’ due to the drag of
the cutting unit when working on the ground.
Rear Weights
May be required to maintain a reasonable amount of rear axle load on the Opposite
wheel from the arms when in work; for normal off-ground work i.e. hedge cutting this
should be 20% of rear axle weight or more for adequate control, and for ground work
i.e. verge mowing with experienced operators, this can be reduced to 10%. All factors
must be addressed in order to match the type and nature of the equipment added to
the circumstances under which it will be used –in the instance of reach arm hedge
cutters it must be remembered that the machines centre of gravity during work will be
constantly moving and will differ from that during transport mode, therefore balance
becomes critical.

Spearhead QUADSAW 1602/2002/2402
11
Factors That Affect Stability
Centre of gravity of the tractor/machine combination.
Geometric condition e.g. position of the cutting head and ballast.
Weight, track width and wheelbase of the tractor.
Acceleration, braking, turning and the relative position of the cutting head during
these operations.
Ground conditions, e.g. slope, grip, load capability of the soil/surface.
Rigidity of implement mounting.
Suggestions To Increase Stability
Increasing wheel track; a vehicle with a wider wheel track is more stable.
Ballasting the wheel; it is preferable to use external weights but liquid can be
added to around 75% of the tyre volume –water with anti-freeze or the heavier
Calcium Chloride alternative can be used.
Addition of weights –care should be taken in selecting the location of the
weights to ensure they are added to a position that offers the greatest
advantage.
Front axle locking (check with tractor manufacturer).
NOTE: The advice above is offered as a guide for stability only and is not a
guide to vehicle strength. It is recommended that you consult your vehicle
manufacturer or local dealer to obtain specific advice on this subject,
additionally advice should be sought from a tyre specialist with regard to tyre
pressures and ratings suitable for the type and nature of the machine you intend
to fit.
