IMPORTANT
VERIFICATION OF WARRANTY REGISTRATION
Dealer Warranty Information & Registration Verification
It is imperative that the selling dealer registers this machine with McConnel Limited before
delivery to the end user –failure to do so may affect the validity of the machine warranty.
To register machines; log onto https://my.mcconnel.com and select ‘Machine Registration’
which can be found in the ‘Warranty’section of the site. Confirm to the customer that
the machine has been registered by completing the verification form below.

Note to Customer / Owner
Please ensure the section above has been completed and signed by the dealer to verify
your machine has been registered with McConnel 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 machine’s general maintenance procedure.

FLAIL MOWER & TRACTOR PRE-OPERATION INSPECTION
A daily equipment inspection of machine and tractor
should be conducted before the equipment is used.
Use the inspection sheets on the following pages to assist with these daily inspections.
Damaged or missing guards should be repaired or replaced before operating the

from the mower and possibly hitting the operator and/or bystanders.
Inspect the Mower for Safe Operating Condition
•Make sure the driveline guards and shielding are in place and in good repair.
•Inspect the chain guards, flexible and/or solid defector thrown object shielding to
assure that they are in place on the front and rear of the mower deck and in good
repair. Repair or replace any damaged or missing thrown object shields.
•Ensure the mower cutting height is set high enough to reduce the possibility of the
mower blades contacting the ground. Actual height will be dependent on the ground
conditions. Increase the height when working in rough or undulating conditions.
•Inspect for broken, chipped, bent, missing, or severely worn blades. Replace damaged
blades before operating the mower. Ensure the blade retaining bolts and fasteners are
secure and tight.
•Lubricate the driveline universal joints and telescoping members daily.
•Inspect the wheel lug bolt/nuts to assure that they are tight.
•If mower is equipped with pneumatic tyres, make sure they have the required air
pressure.
•Inspect for worn or damaged decals and safety instructions. Replace any unreadable,
damaged or missing safety decals.
•Follow the operator’s manual(s) inspection and maintenance instructions for lubricating
parts, and keeping thrown object shielding, driveline guards, rotating parts shields,
mower blades and decals in good repair.
Inspect the Tractor for Safe Operating Condition

MACHINE DESCRIPTION & PURPOSE OF USE
The Magnum 245, 270 & 300 series of machines are ‘3-point linkage’ tractor mounted
heavy duty professional mowers designed primarily for the mulching of maize, grasses,
bushes, branches, vines, and general crop residues. Their strong, tough construction with
working widths of 2.4, 2.7 or 3.0m and offset capability of over 0.5m makes them ideal for
maintenance use in all green areas, vineyards, orchards, on verges and in scrubland by
farmers and contractors alike.
These machines should only be used to perform tasks for which they were designed – use
of the machine for any other function may be both dangerous to persons and damaging to
components and is therefore not advisable.
MACHINE IDENTIFICATION
Each machine is fitted with an identification plate with the following information:
1. Machine (Part Number)
2. Machine Serial No.
3. Machine Weight
When ordering spares or replacement parts from
your local dealer it is important to quote both Part
Number and Serial Number as stated on the
identification plate so the machine and model can
be quickly and correctly identified.

SAFETY INFORMATION
General safety rules:
▲Always read and follow the instructions for the use and maintenance of the machine
before carrying out any work operations or servicing tasks.
▲Improper use of the machine is both highly dangerous to persons and damaging to the
machine components – only use the machine for its designated task.
▲Both operators and the maintenance fitters should be familiar with the machine and
fully aware of dangers surrounding improper use or incorrect repairs.
▲Before starting, checks to both tractor and machine must be carried out as regards:
functionality, road safety, accident prevention rules.
▲Even when using the machine correctly, stones or other objects may be thrown a long
distance. Therefore nobody must stand within the danger area. Special attention must
be paid when working near roads or buildings.
▲Use tractor’s fitted with safety cabs.
▲The condition of flails and of machine guards must be checked before beginning the
daily work - they must be replaced if damaged or missing before you use the machine.
▲During checks or repairs, make sure nobody could start the machine by mistake.
▲Never wear loose or fluttering clothes.
▲Never carry passengers on the tractor.
▲Never carry passengers on the machine.
▲Never connect the power takeoff with the engine running.
▲Never approach the machine until the rotor has completely stopped.
▲Do not enter the working zone of the PTO shaft. It is dangerous to approach the
rotating parts of a machine.
▲Keep the PTO shaft guard in good condition.
▲Before starting, check the surrounding area for the likely presence of children and/or
animals.
▲Do not stand near the machine when it is operating.
▲The PTO shaft must be assembled and disassembled only with the engine stopped
and the starting key removed.
▲Before connecting the power takeoff, check that the speed and the rotational direction
correspond to those of the machine.
▲Immediately replace missing or damaged safety decals.
▲Before leaving the tractor with the machine attached, proceed as follows:
1. Disconnect the power takeoff,
2. Put the machine steadily on the ground using the tractor’s hydraulic lift.
3. Apply the hand brake and, if the ground is steeply sloping, wedge the tractor.
4. Remove the starting key.

5
Transportation Safety
▲In transport, reduce speed, especially on bumpy roads, the weight of the machine may
render driving difficult and damage the machine itself.
▲Ensure the levers that operate the hydraulic lift are locked, to avoid the lowering of the
machine during transport.
▲When driving on public roads, respect all road rules in force.
▲Never transport the machine with the rotor running, even for short distances.
Operating Safety
▲Pay special attention when working with the machine not to touch fixed objects such as
road drain, walls, shafts, kerbs, guard rails, tracks etc. This could cause the breakage
of the flails, which would be thrown out of the machine at very high speed.
▲If wires, ropes or chains should become entangled in the rotor stop immediately to
prevent damage or dangerous situations; stop the rotor and the tractor, take out the
starting key. Put working gloves on; clear the rotor with the aid of pliers or shears. Do
not try to disentangle by inverting the rotational direction of the rotor.
▲Do not use the machine when excessive vibration is experienced, as this may cause
breakage and serious damage - find the cause of the vibration and eliminate it before
using the machine again.
Although the information given here covers a wide range of safety subjects, it is impossible to
predict every eventuality that can occur under differing circumstances whilst operating this machine.
No advice given here can replace ‘good common sense’ and ‘total awareness’ at all times, but will go
a long way towards the safe use of your McConnel machine.
SAFETY DECALS
1. Always switch machine off, remove starting key and read instruction manual before
performing service or maintenance work on the machine.
2. Keep a safe distance from the machine at all times - risk from projection of objects.
3. Risk of hand injury – always ensure all guard are fitted and in place when machine
is operating.
4. Risk of feet injury – keep at a safe distance from the machine when it is operating.
5. Never stand or ride on the machine.
