Description of Machine
The Duncan ‘Mk4 Renovator’ is a Coil Tine T-boot drill.
The box is mounted on a robust frame accommodating
large diameter tyres. The ground engaging components
are controlled by a hydraulic ram system, giving ample
control on ground pressure, good transport clearance
and contour following ability. Sowing depth is controlled
by adjusting the hydraulic ram as required. The quality
European type peg roller seeder system handles all
seeds from turnip and rape through to peas and maize.
The seeders are driven from the groundwheels via a
jockey wheel system and variable speed gearbox. For
transport, the drive is easily disconnected by raising the
drill to its transport height.
Working Principle
The gearbox, pegged seed rollers and seeder flaps are
set to give the desired seed rate. The coil tine and Tboot, create the seed bed. Seed flows down the flexible
tubes between seeder and tee-boot units, and drops into
the prepared seed bed.

SAFETY - General (Continued)
Handle Agricultural Chemicals Safely
All farm chemicals should be stored, used, handled and
disposed of safely and in accordance with the supplier’s/
manufacturer’s recommendations.
Read the product label before using, noting any warnings
or special cautions, including any protective clothing or
equipment that may be required, ie. respirator.
Do not eat or smoke while handling sprays, fertilisers, coated
seeds, etc. Afterwards, always wash your hands and face
before you eat, drink, smoke, or use the toilet.
Store sprays, fertilisers, coated seeds, etc. out of reach of
children and pets, and away from food and animal feeds.
Any symptoms of illness during or after using chemicals
should be treated according to the supplier’s/manufacturer’s
recommendations. If severe, call a physician or get the
patient to hospital immediately. Keep the container and/or
label for reference.
Avoid High Pressure Fluids
Avoid any contact with fluids leaking under pressure, because
the fluids can penetrate the skin surface.
Any fluid which penetrates the skin, will need to be removed
immediately by a medical expert. Seek specialist advice on
this type of injury.
Relieve the pressure before disconnecting any hydraulic or
other lines. Make all repairs and tighten all fittings before
re-connection to pressurised fluid.
Keep your hands and body away from any pinholes or high
pressure jets. Search for leaks with a piece of cardboard
instead of using your hand directly.
Safe Work Practices
All farm machinery is potentially dangerous and should be
treated with caution and respect.
Before starting the machine, ensure that all controls are placed
in neutral and that bystanders are well clear. Check that the
guards have been securely fitted and that any adjustments
have been made correctly.
Where possible, disconnect or isolate the drive mechanism to
the implement. Lower the machine onto the ground when not
in use.
Do not operate this equipment when severe weather
conditions appear imminent.

Transport
1 Raise the drill into the transport position and hold at the full
extent of the rams for a few seconds to allow cylinders to
rephase/equalise.
2
Important - To avoid machine damage due to drill
lowering during transport, always close the hydraulic valve
on the drawbar. Move the handle to a position at
90
0
to the hydraulic line as shown in Fig 1. This
applies to the drawbar and disc opener hydraulic
valves where fitted.
3 Locate jack stand in transport position, if fitted.
Refer Fig 2.
4 Ensure lighting and oversize warning
requirements meet recommendations published by
the local Land Transport Authority or equivalent.
5
Maximum towing speed 40 km/hr.
For countries other than New Zealand
greater speed restrictions may apply, please
refer to your local transport authority.
Ensure towing vehicle requirements are
adequate for the towed vehicle e.g. mass, brakes. Refer to
recommendations published by the local Land Transport
Authority or equivalent.
Braking when towing can cause the load to jackknife. Use
extra care when towing in adverse conditions such as mud,
inclines and sharp bends.
Lower towing speeds are recommmended on farm roads/
tracks and where one wheel is on or over a road verge.
6
Attach safety chains to tractor. Refer Fig 3.
Safety chains must be crossed over underneath the
coupling and attached to the towing vehicle. The
attachment points must be as close as practical to the
towing coupling and one each side.The towbar on the
towing vehicle must be rated for the towed mass. Do not
remove or replace the safety chains provided with any
other than those specified in the parts manual.
Note: The safety chains are provided with sufficient
length to cater for all towing vehicles. Safety chains must
be shortened by cutting off excess length so that if the
coupling fails the drawbar will not hit the ground.
7 If the machine is fitted with row markers or other vertical
extensions, check clearance under power lines en route.
8 Important - For greater disc opener ground clearance,
adjust the ram or turnbuckle on the disc opener unit so
they are at maximum height, and/or extend the drawbar
ram or turnbuckle to level the machine chassis.

Operation
General Operation Guidelines
1 Use a sufficiently powerful tractor which is heavy enough to tow the drill safely.
2 Operate the drill at a speed of 6-12 km/hr (4-8 mph).
In stony and uneven ground conditions a lower speed is more appropriate
3 Check that the drill is level during calibration and while seeding.
4 Check tyre pressure before seeding. Refer page 5.
5 Double check seed rates before seeding.
6 Raise the drill out of the ground when making any turns.
7 Raise the drill out of the ground before backing up.
8 Stretched sagging hoses disrupt seed flow. Slight tension may be restored by
carefully shortening the affected hose; remove from the tube at ground level and cut
accordingly.
Care must be taken not to shorten too much as the tension will pull the hose from the
ground tube or damage the plastic metering funnel.
9 After prolonged storage, check to see that all drive mechanisms and hydraulic equipment
are functioning correctly. Check that the seed tubes are not perished or blocked.
Sowing Speed
Typical travel speeds when sowing range from 6-12 km/hr in good conditions. In stoney
and uneven ground conditions a lower speed is recommended to minimise rapid part
deterioration. Sowing too fast can result in:
1 Poor contour following and uneven sowing depth.
2 Impact damage to:
a Ground engaging components.
b Bearings, housings & axles.
c Fasteners & structural components.
3 More extreme conditions will result in greater vibration
and uneven seed flow at low seeding rates.
Sowing Depth Control
The sowing depth is dependent on:
1 The wheel height in relation to the chassis
2 Tyre pressure
3 Ground condition i.e. hard or soft
The wheel height in relation to the chassis is controlled
using the threaded depth adjustment collar (1) on the
non-drive wheel leg ram. The rams are phasing and
only require depth stops under the master cylinder.
Caution: Do not overextend the thread depth adjustment
collar. Additional collars may be required.
1
16
Level Drill
Use the drawbar turnbuckle or ram to tilt the drill so it is
sitting level. An adjustment may be required after a short
period of use because the paint wears off the discs and
the discs sharpen which in turn improves the penetration
abilities.
Ensure that the front and rear rows are at an even depth.
Transport Position
When in the transport position the hydraulic cylinders are
fully extended. In this position the cylinders fully equalise
by allowing oil to bypass the master cylinder piston. It is
recommended to raise the drill into the transport position
when turning at headlands or regularly to counteract the
effects of oil leakage past the piston and ensure cylinder
rods are equally extended and minimise variations in
sowing depth.
Coulter Penetration Depth
To create the ideal seed bed the disc opener coulter
should cut approximately 20mm below the inverted
tee point. In hard and dry conditions this may not be
achievable, and better machine/sowing performance may
be achieved without using the disc openers. An indication
of this will be the machine bouncing which will result in
uneven sowing depth.
Coulters will give better penetration ability as they sharpen
with use.

Basic Calibration Procedure
Gearbox Setting Lever
To set the seed rate at the gearbox, slacken the tri knob (1) by
turning counter-clockwise and push from below into the position
indicated in the Sowing Chart. Retighten the star knob firmly
(Fig 6).
Important
The settings shown in the Sowing Charts (kg/ha) can only
serve as reference values. Deviations may occur caused by
differences in the size, shape, density of the grain and by the
dressing agent. Therefore prior to any sowing, always carry
out calibration trials to accurately determine the actual
seed rate.
Using the stepless variable speed gearbox, the speed of the
metering shaft and thus the seed rate is set steplessly. The
higher the figure indicated on the scale by the setting lever the
greater the seed rate (Fig 6).
Selecting the Gear Ratio
The Seed Drill is designed with a two speed (high and low) gear
ratio arrangement where the moving of the chain from a 21 x 13
teeth ratio to a 13 x 21 teeth ratio changes the output from high
to low (Fig 7). The selection and method for changing the ratio
is detailed under Speed Setting Page 27.
Setting Seeder Shutter Slides
The varying flow properties of seeds require different shutter
slide positions which may be found in the Sowing Chart for the
individual type of seed. This corresponds to one of the three
settings in Fig 8.
Bottom Flap Settings
The various seed sizes require matching bottom flap clearances
below the metering wheel. The adjusting plate allows for 10
different settings. The required position for the seed type may
be found in the Sowing Chart. The control levers are located on
the LH end of the seedbox, (opposite end to the gearbox).
Number “1” corresponds to the minimum (closed) position and
“10” the maximum gap (Fig 9).

Basic Calibration Procedure
(Continued)
Seed Calibration
The calibration test should be done to confirm the required
seed rate and is done with the drill stationary and level.
Seed Calibration Procedures
1 Remove the calibration tray from the storage brackets
on the seedbox. Place the calibration tray (1) on the
support members below the seeders (Fig 10).
2 Position all the clear plastic seed diverters (2) to redirect
the seed into the calibration tray (Fig 10).
3 Make sure all the shutters are open and set to the
position indicated in the seed charts for the particular
seed.
4 Agitator Shaft - Check the Seed Chart “Hints” (Table 3)
whether to connect or disconnect the shaft by removing
the M10 bolt (1) during seeding (Fig 11).
5 For the test, half fill the box with seed. If this is not
possible make sure the seed is evenly distributed within
the box.
6 For setting method refer to Basic Calibration Procedures
(Page 22)
.
Note For seeds which are not covered in the respective
Sowing Chart (Page 19 to 21), use the figures for a seed of
comparable size and shape.
7 Place the crank handle (1) over the hexagonal drive dog
on the transfer shaft and turn anti-clockwise until the
seed flows consistently from the seeders (Fig 12). To
ensure complete filling of the seed unit continue turning
the crank until an even flow of seed is coming out of the
seeder units, then empty into the seedbox. The drill is
now ready for calibration.
8 Turn the crank handle anti-clockwise the required
number of revolutions as detailed in Table 5.
Note The Calibration is usually done for 1/40th hectare.
For very small seed rates or when using inaccurate
scales (i.e. unable to measure to the nearest gram) the
calculation based on 1/10th hectare should be used.
Scales must be accurate to 2 grams as any error will
be multiplied by either 10 or 40 giving inaccurate
calibration results.

Basic Calibration Procedure (Continued)
Hand Crank Turns for Seed Rate Calibration
The tables represented below are for arable conditions (worked ground) and
are calculated to indicate an average situation. If there is any doubt as to the
accuracy of these figures for the conditions, it is advisable to run checks on
the calibration figures listed. Refer Page 26, (Wheel Slip Deviations). Check
and record which tyres are fitted to your drill, to ensure use of the correct
Hand Crank Turn and Constant figures.
9 Weigh the seed collected during the test in kilograms.
Caution: Scales must be accurate to 2 grams, as any error will be multiplied
by either 10 or 40, giving inaccurate calibration results.
10 Calculate the seed rate by multiplying the kgs previously collected x 40 (1/40th
ha method, refer Table 6) or x 10 (1/10th ha method, refer Table 7) depending
on the requirement. If the resultant calculation does not produce the desired
seed rate use the enclosed seed rate calculator disc to determine the correct
gearbox setting.
Refer Use of Seed Rate Calculator Page 25.
Suggestion: To be on the safe side and until confidence has been gained
with the method of calibration it is advisable to conduct a second test at the
newly determined gearbox setting.
11 Where a coated seed is used it is advisable to check the calibration after
1 hectare as dressings can tend to create a coating on the seed metering
wheels thus changing the the flowing properties of the seed which in turn
alters the seed rate.
For 1/40 Hectare (250m2) Calibration
Seed Rate = Actual Seed Collected (kg) x 40
For 1/10 Hectare (1000m2) Calibration
Seed Rate = Actual Seed Collected (kg) x 10

Basic Calibration Procedure (Continued)
Use of Seed Rate Calculator
Determining the gear box scale setting using the calculator.
Usually the first calibration test yields a different seed rate. However with the value determined
from the first test it is possible to determine the correct gearbox setting with the aid of the
enclosed disc calculator (Fig 13). The disc calculator consists of 3 scales. An outer white scale
(1) for all seed rates above 30 kg/ha and an inner scale (2) for all seed rates below 30 kg/ha.
On the middle coloured scale (3) are all the gearbox setting numbers to a maximum value of
100.
Fig 13
Setting Example (Desired Seed Rate 125kg/ha)
1 From the calibration procedure at a gearbox lever setting of “70”, a seed rate of 175 kg/ha
is obtained.
2 Turn the inner disc until the measured seed rate of 175kg/ha (A) is in line with the related
actual gearbox setting of “70”(B) (Fig 13).
3 Read off from the disc rule the necessary gearbox setting for the required seed rate of
125kg/ha (C). In this example the correct setting is “50” (D) (Fig 13).
4 To be on the safe side the new gearbox setting can be checked by another calibration test.
26
Basic Calibration Procedure (Continued)
Calibration Deviations
Deviations Between the Calibration Test and the Actual Seed Rate
The most frequent cause for changes between the calibration test and the seed rate lies in the
flowing properties of seed during sowing. These changes in properties generally result from
reactions of the dressing agents to temperature, humidity or abrasion. These changes will
become even more obvious when the bottom flaps are incorrectly set. If the setting of these
flaps leaves too large a gap an uncontrollable additional flow of seed can occur during seeding;
especially when assisted by the drill bouncing, a condition not simulated while conducting the
calibration tests. For this reason the basic setting of the bottom flaps should be checked at
regular intervals.
Residues from the seed dressing on the bottom flaps and metering wheels can also influence
the flowing properties of the seed and thus the seed rate. In such cases a balance will occur
only after a period of time and it is recommended to repeat the calibration test to confirm the
seed rate after 2-3 seedbox fillings, nominally when the seed box is half empty. Only then will a
balance occur and the seed rate will stabilise.
Wheel Slip Deviations
It is always possible with rubber tyred drills in extreme ground conditions to get wheel slip. Not
normally a problem with cleated type tyres in good condition, but more so in the arable situation
with the less agressive tread patterns. The result: large differences between the calibration test
and the actual sowing rate, obviously less seed deposited than required. The number of crank
turns indicated below is correct in most circumstances other than those mentioned above.
To check number of crank turns for calibration
Should you require to check this in a practical way proceed as follows:
For an area of 250m
2
(1/40 Hectare), the travel distance for your machine is shown below.
Place the crank handle over the hexagonal drive dog on the gearbox. Move the machine
forward over the measured distance, counting the number of turns of the crank handle as you
go. Using this number of crank turns repeat the calibration.

Hints for Sowing with Variable Speed
Gearbox
The gearbox allows for stepless changes in the speed of
the metering shaft and thus the seed rates. Due to the
variations in seed type and application rates there are two
speed ranges available.
By changing from High Speed to Low Speed the range of
settings and control is dramatically increased.
Change to the Low Speed when the gearbox setting is
down to 10 on the scale and the desired seed rate cannot
be obtained.
To change the speed setting from high to low, remove the
wing nut (1) and chain cover.(2) (Fig 14).
Release the tension on the chain (1) by forcing back the
chain tensioner (2) and hold in place with the hook. Refer
Figure 15. Remove the chain from the 21 tooth output
sprocket to the 13 tooth sprocket, then remove the chain
from the 13 tooth gearbox sprocket to the 21 tooth. Check
the chain is correctly aligned then release the chain
tensioner. Ensure the tension roller is correctly aligned
with the chain. Replace guard and calibrate as required.
To Determine the Gearbox Setting after a
Speed Change
For determining the correct gearbox setting after the speed
change, conduct the first test at 50. With the weight of
seed collected find your correct setting with the aid of the
disc calculator; refer Page 25, Fig 13.
Sowing of Fine Seeds
For sowing small seeds the Renovator Drill is equipped as
standard with a combined normal and small seed
metering
wheel (1). During grain sowing and other larger varieties of
seed both the large and small seed metering wheels are
coupled and both rotate. In order to convert the seed drill to
sow fine seed insert the crank handle and rotate clockwise
until the holes
(2) of the small seed wheel are visible (Fig
16)
Using the tool supplied (3) disengage the the pin inside
the hole so that the large metering wheel rotates freely
on the metering shaft.
When seed is to be sown again using the normal metering
wheel press the pin, from the large metering wheel side
(opposite direction to before), using the tool, back into the
hole of the small seed wheel thus reconnecting the drive
between the two.

Caution - When resetting the metering wheels
on the seeder shaft
Care should be taken when tightening the grub screws
on the small seed wheel. Adjust the grubscrew until the
movement of the metering wheel just stops, then tighten no
more than 1/8 of a turn.
Do not overtighten as this can result in breakages while
operating and may render the warranty on these units void.
Small Seeds
Calibration with Disconnected Agitator Shaft
The small seed metering wheel used in Duncan Drills is
especially well suited for sowing small seeds such as rape,
turnips and clover.
Due to the intensive action caused by the agitator the seeds
can adhere to each other, or be damaged, causing irregular
sowing/germination. Therefore it is recommended that
when sowing small seeds, especially oil seeds and thin
shelled seeds, the drive to the agitator is disconnected.
To do this remove the linch pin or bolt. (1) (Fig 18).
Deviations between the calibrated and actual seed rate can
occur when residual dressing agent sticks to the bottom
flaps and thus slows the flow of seed. Before beginning the
actual calibration test fill the calibration trays by turning the
crank handle at a high speed around the 90 setting on the
gearbox scale. This will cause an immediate buildup of the
dresssing agent on the flaps. Return the contents of the
calibration trays to the seed box and proceed with the actual
calibration. Due to the residue buildup on the flaps your
calibration will now reflect accurately the required seed rate.
Note - Remember to reconnect the agitator shaft as required
for other seeds otherwise the consistency of seed rate will be
affected.
Sowing Peas
Peas having the size and shape as illustrated in Fig 19A
(e.g. White Field Peas), can be sown in all Duncan Drills with
this type of metering wheel.
The flap should be set to a gap of at least “3” on the flap
setting lever (Page 22, Fig 9).
With these peas it should not be necessary to run the
agitator shaft.
Peas having the size and shape as illustrated in Fig 19B (e.g.
Green or Garden Peas), tend to bridge inside the seedbox
and do not flow freely.
This multi-faceted pea requires agitation for sowing.

Computronics 1100 Area Meter Setup for Mk4 Renovator
The H1 value is the distance the machine travels in mm per pulse
detected on the pedestal drive shaft.
This is affected by:-
- jockey wheel diameter
- if there is wheel slip
- the gear ratio (13T on the jockey axle and 38T on the sensor mainshaft).
Ensure that the jockey wheel is inflated to the recommended pressure. (Page 5)
The H2 value is calculated from the number of rows x row spacing (in metres)
It is advisable, as with all things electronic, to have a backup of your totals. We suggest you record

Maintenance & Care
General Safety and Accident Prevention Advice
1 Make sure that if the tractor remains attached to the drill
that the ignition key is removed.
2 During maintenance the drill should be supported in such
a manner that if hydraulic failure was to occur the machine
would still be adequately supported.
3 Wear gloves when handling components with cutting
edges such as worn discs etc...
4 Disconnect the electrical supply from the tractor before
doing any electrical maintenance.
5 Refer to safety sections for more safety information.
General Cautionary Maintenance Advice
1 Electric Welding - With the electronic equipment in
modern tractors it is advisable to completely disconnect the
implement from the tractor, or at the very least disconnect
the alternator before attempting any welding.
2 Hydraulics - Ensure hydraulic couplings (male & female)
are clean before connecting. Dirty couplings will result in
hydraulic oil contamination and hydraulic cylinder seal/
poppet valve damage and bore scores. This in turn will
result in oil leakage past the piston seals.
No filter is fitted to the hydraulic system. If hydraulic
fittings and oil supply are not going to be kept clean it is
recommended that a filter be fitted to prevent hydraulic
cylinder damage.
3 Water Blasting - Water blasting, steam cleaning or other
pressurised cleaning processes can force dirt etc. into
undesirable places that may cause damage or rapid part
wear to items such as bearings, seals, chains, bushes etc.
Caution must be exercised.

1 Bolted Connections
All bolted connections of the machine should be checked after the first 3 to 5 hours of operation and
retightened if necessary and thereafter at regular intervals. It is suggested that this is done every 500
hectares or annually, whichever occurs first.
2 Gearbox
The oil level in the gearbox can be seen in the oil gauge window. Changing the gearbox oil is
recommended once a year or sooner if the oil is discoloured. For refilling the oil remove the 1/2” BSP
plug on the top face of the gearbox, Castrol Oil Agri Trans Plus or equivalent* should be used.

3 Drive Chains
All drive chains (1) (Fig 25) should first be checked
after every 20 hours of operation and thereafter
weekly or after 75Ha of operation as follows:-
The metering wheels of the seed drill are driven via
roller chains from the drive wheel.
Cleaning of the roller chains is recommended after
long periods of operation. Remove the chain, wash in
kerosene and then dip them in heated grease or oil
or spray them with a suitable commercial roller chain
lubricant.
4 Wheel Arm Pivots
Wheel arm pivots must be greased regularly (weekly
or after every 75Ha) to provide lubrication and flush
out any dirt. Refer Fig 26 (1).
5. Depth Adjustment Collar
Grease the depth adjustment collar (2) regularly to
ensure it does not seize up. Also check for dirt buildup
around the ram shaft seals to ensure seal damage
does not occur. Refer Fig 26
6. Tyre Pressure
Refer to Page 5 Dimensions & Capacities
7. Disc Openers
Front coulter bearings are sealed and do not require
lubrication. Check discs for any lateral movement
(wobble) on a regular basis. Replace bearings if there
is any noticeable wobble.
There is one grease nipple on each disc opener frame
pivot and disc assembly casting. Frame pivots should
be greased monthly while disc castings should be
greased daily to provide lubrication and to flush out
any dirt.
8. Length of Seed/Fertiliser Tubes
These tubes can stretch over a period of time and
require checking at approximately six monthly
intervals. Shorten if necessary to avoid bends which
will restrict the flow of seed/fertiliser.
9 Framework
The framework structure should be inspected annually
for defects, i.e., cracks in members or welded
connections. The framework should be cleaned prior
to the inspection.

Maintenance & Care (Continued)
10 Bottom Flaps (Fig 28)
The required seed rate is controlled by both the metering
wheels and the bottom flaps. The seed flows from the seed
box into the metering wheel housings. Inside the metering
wheel housing (1) the seed is caught between the metering
wheel (2) and the bottom flap (3). The metered amount
of seed is transported by the metering wheel to the edge
of the bottom flap where it drops off into the seed guide
tube which leads to the coulter. Varying grain sizes require
the matching of the flap clearance to the different grain
sizes. This matching is done by raising or lowering the
bottom flaps by using the flap adjusting lever on the LH
end of the seed box. If larger foreign particles, e.g. stones
get between the metering wheel and the bottom flap, the
bottom flap can give way downwards. A strong return
spring (4) brings the bottom flap immediately back into the
working position.
The metering system should be checked every 1/2 year
or before any sowing period with an empty seed box
and empty metering housings.
Use the following procedure:
Put the bottom flap setting levers (1) (located on the LH
end of the seed boxes) in position “1” for the front box and
position “1” for the rear box. Refer Fig 29.
By turning the metering wheel shaft by hand check the
flaps are all set to a gap of 0.1 to 0.5mm (refer Fig 28).
To adjust individual flaps use the spring tensioning screw
(5) (Fig 28).
Note: Maintenance Schedule (page 24)
Where the frequency is given in terms of use (eg. weekly) or
area covered (eg. 75 Ha) perform the maintenance task based
on whichever occurs first.
Preparing the Machine for Storage.
Locate on a dry level surface. The machine should be stored
wherever possible so the rams are not supporting any weight.
The drive chains should be lubricated with suitable roller chain
lubricant before prolonged periods of storage.
For longer term storage remove seed/fertiliser tubes from the
boot assembly and allow to hang without deformation. Check
tube lengths when replacing.
It is recommended that maintenance be carried out at the end
of the season, giving sufficient time to obtain spare parts and/
or carry out repairs if required.

Commisioning Phasing Cylinders
1. General
(a) The cylinders will re-phase in both directions. Each piston is fitted with 2 poppet valves which open at
the end of the stroke to allow oil to bypass the piston. The bypass of oil at the end of the stroke allows for
initial bleeding of the system and re-phasing in operation.
(b) The valve in the piston is a precision device, CLEANLINESS IS OF THE UTMOST IMPORTANCE.
Contamination in the oil will accelerate deterioration of the valve seat. Cylinders will creep once the
integrity of the seating is lost.
2. Bleeding the System
(a) Initial bleeding after connection to the tractor
Purge all air from the system by fully stroking rams in both directions. Allow the oil to flow through the
cylinders with the tractor at an idle for a minimum of 2 minutes at each end of the stroke.
(b) Re-phasing after initial bleeding
After initial bleeding the cylinders will only require occasional re-phasing during operation. This is done by
extending the rams for about 30 seconds or until all cylinders have reached the end of their stroke.
3. Fault Finding
1. Cylinders creeping during operation
There are two primary causes of this:
(i) Air in the hydraulic system
(ii) By passing of the poppet valve.
(a) Check that there is no air in the system. Raise and lower the machine. All cylinders should move
instantaneously, any lag indicates that there is air in the system. Other signs of air in the system are hoses
vibrating/squealing or the control handle shuddering. Re-bleed the system if necessary.
(b) If there is no sign of air in the system and the cylinders still creep, raise the machine off the depth stop
and measure the movement of each cylinder rod.
(c) If both cylinders move at the same rate it is likely to be the control valve/lock out valve that is leaking.
(d) If the slave continues moving after the master cylinder has hit the depth stop it is likely to be the piston
in the master cylinder that is bypassing.
(e) If the slave cylinder extends while the master cylinder retracts it is likely to the the piston in the master
cylinder that is bypassing.
(f) If the master cylinder does not move but the slave does it is likely to be the piston in the slave cylinder
that is bypassing.
(g) If the piston is bypassing it is likely to be contamination in the phasing valve. The cylinder will have to
be dismantled, cleaned and fitted with a new poppet valve.

Commisioning Phasing Cylinders (continued)
3. Fault Finding (continued)
2. Cylinders moving at different rates
(a) Check that there is no air in the system. Raise and lower the machine; all cylinders should move at the
same time, any lag indicates that there is air in the system. Re-bleed the system if necessary.
(b) Ensure that the cylinders have been connected correctly. The cylinders should be connected in series
so that the bore sizes go down in 1/4” increments. The Rod end port of the master cylinder (3.5” bore) is
connected to the piston end port of the slave cylinder (3.25” bore).
