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 go to the McConnel Limited web site at www.mcconnel.com, log
onto ‘Dealer Inside’ and select the ‘Machine Registration button’which can be found in
the Service Section of the site. Confirm to the customer that the machine has been
registered in the section below.
Should you experience any problems registering a machine in this manner please contact
the McConnel Service Department on 01584 875848.

NOTE TO CUSTOMER / OWNER
Please ensure that the above section above has been completed and signed by the selling
dealer to verify that 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 machines generalmaintenance procedure.

Machine Identification Plate
MACHINE DESCRIPTION & PURPOSE OF USE
These machines which are commonly known throughout the agricultural industry as
Yardscrapers are intended for use attached to an agricultural vehicle by means of the
‘three-point linkage’ couple up system; a quick hitch attachment is available as an extra.
The machines, which have robust frames and hardwearing rubber blades, are designed for
the sole purpose of scraping yards and lanes that have a reasonably flat surface.
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.
▲When using the machine all bystanders and onlookers should be kept at a safe
distance from the tractor and machine. Special attention must be paid when working in
or near buildings.
▲Use tractor’s fitted with safety cabs.
▲The condition of the machine must be checked before use –do not use the machine if
components are missing or damaged.
▲During checks or repairs, make sure nobody could start the machine by mistake.
▲Never wear loose or fluttering clothes when operating machines.
▲Never carry passengers on the tractor.
▲Never carry passengers on the machine.
▲Never connect the power takeoff with the engine running.
▲Never leave the tractor seat whilst the engine or machine is running.
▲Do not enter the working zone of the tractors PTO shaft.
▲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, or approach, the machine when it is raised or operating.
▲The PTO shaft of a tractor 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.
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.

4
Operating Safety
▲Pay special attention when working with the machine not to touch fixed objects such as
drains, walls, kerbs, guard rails, tracks etc.
▲Always lower the machine to rest on the ground when not in use.
▲Always ensure the machine is safely supported before attempting to carry out repairs
or maintenance. Never work on a machine that is raised or unsupported.
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.

VEHICLE / TRACTOR PREPARATION
We recommend vehicles are fitted with
cabs using ‘safety glass’ windows and
protective guarding when used with our
machines.
Fit Operator Guard (part no. 7313324)
using the hooks provided. Shape the
mesh to cover all vulnerable areas.
Remember the driver must be looking
through mesh and/or polycarbonate
glazing when viewing the machine in all positions - 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 protective equipment 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 to EN297, gloves, filter mask and high visibility clothing.
Vehicle Ballast
It is imperative when attaching ‘third-party’ equipment to a vehicle that the maximum
possible stability of the machine and vehicle combination is achieved –this can be
accomplished by the utilisation of ‘ballast’ in order to counter-balance the additional
equipment added.
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 when working.
Where a machine works to the side of the tractor rear weights may be required to maintain
a reasonable amount of rear axle load on the opposing wheel.
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 - factors that effect stability are:
Centre of gravity of the tractor/machine combination.
Geometric conditions, 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 unit during these
operations.
Ground conditions, e.g. slope, grip, load capability of the soil/surface.
Rigidity of implement mounting.
Suggestions to increase stability:
Increasing rear 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.
The advice above is offered as a guide for stability only and is not a guide to vehicle strength. It is
therefore 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.

GENERAL INSTRUCTIONS
1. Attachment of the machine to the tractor should always be performed on a firm level
site.
2. Before and during the maneuvering of the tractor to attach machinery or implements,
make sure that no other persons are in the vicinity. Keep other persons well clear and
make known your intentions, all the while keeping a sharp lookout whilst reversing and
aligning the machines for coupling up.
3. Ensure tractor brakes are applied correctly to prevent the vehicle from moving.
4. Ensure that the lift arms and top link ball ends of the tractor are properly fitted to the
machine or implement using the correct adapter sleeves where necessary, and that
retaining pins of the correct type are used on all three-point linkage points. Secure pins
with the relevant pin and ring assembly.
5. Should it become necessary to make any adjustments or service the machine while
raised on the tractor linkage or front end loader, trestles or suitable supports must be
positioned to support machine to prevent accidental dropping of lift arms or mechanical
failure.
MACHINES MUST ALWAYS BE PROPPED AND CHOCKED.
6. Never attempt to work on, adjust, service or repair machinery of any kind whilst it is still
running or working. Always stop the machine and STOP THE TRACTOR ENGINE
before making adjustments or repairs.
SWITCH OFF THE TRACTOR ENGINE BEFORE LEAVING THE TRACTOR SEAT
7. Always use machines in a sensible and reasonable manner and do not attempt to use
them for work for which they are not intended. Avoid overloading and abusing them as
this can cause damage to machine and tractor and can be very dangerous.
8. When detaching a machine ensure that any stands or legs are securely positioned. The
machine must be parked where it will not be a safety hazard or cause annoyance to
others. Make sure that chosen parking site is firm and level.
9. Carry out regular periodic maintenance, always with safety in mind.
10.Ensure regular maintenance procedures are maintained for the lifetime of the machine.
HEALTH AND SAFETY RULES AND REGULATIONS MUST BE ADHERED TO IN ALL
AGRICULTURAL RESPECTS.

HANDLING & TRANSPORTATION OF THE MACHINE
Suitable overhead lifting gear should be used to move or handle this machine safely. The
machine can be attached to the lifting gear using a chain, rope or lifting strap providing it is
of sufficient strength to support a weight in excess of the machines total weight. Lifting
tackle should be securely attached to the correct lifting point on the machine as indicated
in the photo below.
When raising and moving machinery ensure bystanders are kept clear of the machine at
all times. Once the machine has been moved make sure that it comes to rest in a safe
position and location, supports or stay bars may be necessary to ensure stability of the
machinery. Always use supports or stay bars whenever the machine is transported.

M402 & M452 YARDSCRAPERS –‘SETTING UP’ INSTRUCTIONS
1. Attachment of the tractor to the machine should be performed on a firm level site.
2. Connect machine to three-point linkage of the tractor and couple up in the conventional
manner using the correct link pins, spacers and linch pins.
3. Adjust ‘top link assembly’ length to a setting that positions the ‘A’ frame vertical to the
ground –see illustration below.
4. Ensure scraper is sitting level on the ground (widthways) by adjusting leveling box on
rear tractor linkage arm to suit.
5. The adjusting screws for setting main lower scraping section in relation to the
headstock should now be checked and set. Adjustment screws are located on both
sides of the headstock assembly.
6. Adjust the pair of rear screws ‘downwards’ to raise the front edge of the rubber until a
dimension of 25mm (1”) is reached at the leading edge of the rubber on both sides
(refer below), lock adjustment screws in position by tightening the locknuts.

9
7. Swing the base scraping section up and over through 180°, this will now put the
machine into rear scraping mode, repeat the previous adjustment procedure to the
same dimensions, but this time using the front pair of adjustment screws (refer below).
Once completed the machine will be set for both forward and reverse scraping, no
further adjustment should be required providing the tractor and top link length remain
constant.
ROUTINE MAINTENANCE & LAYING UP
Weekly Maintenance Tasks
Grease pivot points and catch plunger.
(Do not over grease plunger as this will impair it’s movement).
