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 general maintenance procedure.

INTRODUCTION
The McConnel Debris Blower is a self contained unit which blows the debris generated
during flail cutting off the highway and onto the verge. High and low flow versions are
available to suit different models of tractor. If unsure please contact your Local Dealer or
McConnel Limited for advice.
The debris blower is mounted on brackets attached to the hedge cutter and is powered by
the tractors hydraulic system. Various mounting brackets are available to suit a wide range
of McConnel machines.
The angle of the blower may be varied to suit specific applications and conditions.
Debris blowers are suitable for use with hedgecutters with either T.I. (totally independent)
hydraulics; two pumps (one for the arms and one for the cutting head) and S.I. (semi-
independent) hydraulics; a single pump (for the cutting head); the arms being powered
from the tractors hydraulics.

2
SAFETY INFORMATION
In addition to the advice stated below the main safety implications surrounding
the use of this machine relate to the safe use of the hedgecutter it is fitted to; it is
therefore vital that all users have read and understood all safety information in
the operation manual provided with that machine.
General Safety Advice
▲Ensure the operator is, or has been, properly trained to use the machinery.
▲Ensure all safety guards are fitted correctly, are undamaged and kept properly
maintained.
▲Ensure hydraulic pipes are carefully and correctly routed to avoid damage by chaffing,
stretching or pinching and that they are held in place with the correct fittings.
▲Check that the machine fittings and couplings are in good condition and tightened
correctly.
▲Never use a machine that is poorly maintained.
▲Never use a machine if guards are missing or damaged.
▲Never use a machine on which the hydraulic system shows signs of wear or damage.
▲Never use a machine to perform a task it has not been designed to do.
▲Never approach the machine whilst it is running.
▲Never carry out maintenance on any part or component of a machine that is raised
unless the part or component has been properly and substantially braced or supported.
▲Never attempt to detect a hydraulic leak with your hand – use a piece of cardboard.
▲Never allow children near to, or play on, a tractor or machine under any circumstances.
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.

FITTING THE DEBRIS BLOWER
Debris Blowers are attached to the hedgecutter using a mounting kit specifically designed
for the particular machine, a ‘T’ shaped plate which carries the blower unit is then bolted to
the carrier bracket; both are equipped with a series of holes which allows vertical and side
to side adjustment.
The blower carrier bracket, which is bolted to the ‘T’ plate, is furnished with a radial slot to
allow the angle of the blower to be adjusted.
Debris Blower & Mounting Kit Components (Example)
A) Mounting Bracket
B) Carrier Bracket
C) Hose Ring
D) Debris Blower

Note; when fitting is complete there should be 36mm (1½”) of clearance between the
rear of the tank and the blower motor.
It is the aim to mount the blower as far as possible towards the outside edge of the tank to
give maximum coverage of the road. The height to the centre of the blower from the
ground should be approximately 650mm (26”) whilst the angle is decided by operation
experimentation.
These settings are recommendations for general flail operations; it is permissible to vary
the mounting positions should special individual conditions require it.
Hydraulic Connection
Pressure Connection; connect to tractors spool valve to provide flow.
Return Connection; connect to ‘free flow’ return – back pressure must not exceed 1 Bar.
Tractor Oil Flow Rates
Tractors with a closed centre hydraulic system or with an oil flow capability of less than 36
l/min should be fitted with the low flow debris blower. For those with a flow capacity of 36
l/min and above the high flow debris blower should be fitted.
Working a high flow debris blower on a low flow tractor will result in considerably reduced
blow.
Working a low flow debris blower on a high flow tractor will result in the same degree of
blow but the oil will overheat.

5
HYDRAULIC CONNECTIONS - Tractors with ‘Open Centre’ Hydraulics
T.I. Machines
For debris blowers that are fitted to T.I. machines the pressure supply hose is taken from
the tractors single acting auxiliary service and connected to the flow control valve block
opposite the hexagon head of the valve.
The return hose from the motor is connected to the tractors transmission casing. The oil
must be returned beneath the transmission casing oil level. Contact your dealer for the
correct procedure for individual tractors.
Note; where oil is returned to the transmission casing it may be necessary to extend the
return hose.
CAUTION! Connecting the return hose to a tractor’s double acting spool can result
in a blown shaft seal due to back pressure caused by the fan over-run and restricted
return line.
Engagement of the debris blower is by the auxiliary control lever.
S.I. Machines
For debris blowers that are fitted to S.I machines the following modifications need to be
carried out:
The plug from the end of the pressure gallery on the armhead control valve is removed
and replaced with a pressure carry over adaptor, a union and a swivel elbow. The
pressure supply to the debris blower is taken from this swivel elbow to the flow control
valve block on the blower motor opposite the hexagon head of the valve.
The return hose is returned to the tractor transmission casing as for T.I machines
Note; when Debris Blowers are fitted to S.I. machines the debris blower is automatically
engaged when the tractors auxiliary service is selected to power the arms, it does not have
an individual control.

6
HYDRAULIC CONNECTIONS - Tractors with ‘Closed Centre’ Hydraulics
For tractors with closed centre hydraulics the following modifications to both T.I and S.I.
installations are required:
The Tee piece, the long return hose to the tractor and the short return hose from the motor
outlet port should be removed from port ‘T1’.
Port ‘TI’ should be fitted with a blanking plug as shown in the illustration above.
The long return hose is then connected directly to the motor outlet port, oil is then returned
direct to the tractor’s transmission as detailed previously.
OPERATION
The Debris Blower incorporates a speed control valve to govern the fan maximum speed.
Pumping excessive oil through the debris blower will not increase speed and only heat the
oil. After connecting the debris blower it is suggested the following procedure is followed.
Turn the flow control on the tractor's spool to minimum.
Start the debris blower by engaging the spool valve.
Set the engine to normal operating speed.
Turn the flow control up, on the tractor's spool valve, until the debris blower fan
reaches its maximum speed and set it there.
To stop the debris blower reduce the engine speed to idle and move the spool valve lever
into float or neutral. Float is the best option as this allows the motor to run down smoothly.
PORT ‘T1’
Remove Tee piece & return hose
from this port and fit blanking plug.
MOTOR OUTLET PORT
Connect the return hose to tractor
directly from the motor outlet port.
