WINTEX 1000
INTRODUCTION
This workshop manual covers the WINTEX 1000 soil
sampling machine. Amendments and additional
pages will be issued to ensure that the manual covers
latest models.
This workshop manual is designed to assist skilled
Technicians in the efficient repair and maintenance of
the Wintex 1000 soil sampler only, and should not be
used for any other machine.
Individuals who undertake their own repairs should
have some skill and training, and limit repairs to
components which cannot affect the safety of the
machine. Any repairs required to safety critical items
such as the emergency stop system should be carried
out by a WINTEX trained Technician.
Repairs to such items should NEVER be attempted
by untrained individuals.
REPAIRS AND REPLACEMENTS
When replacement parts are required, it is essential
that genuine WINTEX parts are used.
Attention is particularly drawn to the following points
concerning repairs and the fitting of replacement parts
and accessories: Safety features embodied in the
machine may be impaired if other than OEM parts are fitted.
Locking devices where specified, must be
fitted. If the efficiency of a locking device is impaired
during removal, it must be replaced with a new one.
It is advised that certain fasteners must not be re-used
as they may become damaged through disassembly.
PLEASE NOTE:
All numbers in ( ) are for the WINTEX 1000 with a 21 mm probe.

11. Install the 14 mm nut onto the M14 threaded part of the piston rod by using 22 mm spanner on the nut and a 14 mm spanner on the flat end
of the piston rod.
12. Do not fully tighten the 14 mm nut. It is important to allow the end of the piston rod to move slightly. This is important because the soil probe
may try to move sideways if it encounters an obstruction. Allowing the piston rod some movement reduces the risk of damage occurring.
Once the piston has sufficient movement, tighten the 4 mm grub screw in the 14 mm nut using a 2 mm hex key to prevent the nut working
loose.

REPLACING EJECTOR TIP
The ejector tip is attached to the ejector rod by means of a threaded stud. It pushes the sample of soil from the probe into the sample pot.
The ejector tip should travel easily into the soil probe to avoid damage and should be adjusted so that approximately 8-10 mm of the tip extends past
the end of the soil probe. It should be central to the soil probe to prevent excessive wear to both parts and to also ensure all of the soil is fully ejected.
Tools Required:
2 x self locking pliers
1 x metal ruler / vernier calliper
Soft jaw vice
1 x 4 mm hex key
Thread lock
Removal
1. Using self-locking pliers attach one pair to the ejector tip and one pair to the ejector rod.
2. Release the ejector tip by turning anti-clockwise whilst holding the ejector rod still.
3. Place the ejector tip into a vice.
4. Use a 4 mm hex key to undo the M8 threaded stud from the ejector tip.
Refit
1. Place the new ejector tip into a vice with soft jaws to avoid damage.
2. Fit the M8 threaded stud into the ejector tip using a 4 mm hex key. Secure with thread lock.
3. Screw the ejector tip and threaded stud assembly into the ejector rod.
4. Tighten the ejector tip using locking pliers.

EJECTOR ROD ADJUSTMENT
The Ejector rod is designed to force soil which is held in the soil probe into the awaiting collection put as the drilling head assembly moves upwards.
Tools Required:
2 x 17 mm (19 mm) spanners
1 x 2 mm hex key
1 x 4 mm hex key
The drilling head should be approximately 800 mm away from the top of the chassis in order to check that the ejector rod is running centrally to the
soil probe.
If the ejector rod is not running centrally and requires adjustment:
1. Slacken the 10 mm (12 mm) nut on the end of the ejector rod. Do not fully undo.
2. Slacken the three 6 mm hex button head set screws on both ejector rod mounting plates. Do not fully undo.
3. Move the ejector rod so that it runs centrally through the drilling head hub and the soil probe.
4. When in the correct position tighten the six hex button head set screws followed by the 10 mm (12 mm) nut on the end of the ejector rod.

ADJUSTING EJECTOR TIP PROTRUSION
The ejector tip should protrude 8-10 mm from the end of the soil probe when the drilling head and mast are fully retracted to ensure the full soil sample
is ejected.
The amount of protrusion can be adjusted in two ways - a combination of the two may be required.
ALTERING THE HEIGHT LIMITER
The height limiter is found on the bottom of the mast. It dictates how far the mast can fully retract and thus how much distance there is between the
drilling head and chassis when fully retracted. It is therefore extremely important that when adjusting this that the drilling head cannot come into
contact with the chassis or damage will occur, but at the same time being sufficiently adjusted so that the ejector tip protrudes far enough from the end
of the soil probe (8-10 mm).
Tools Required:
2 x 13 mm spanners
Metal ruler
1. Ensure the drilling head and mast are fully retracted.
2. Measure the amount of protrusion and make a note of it.
3. Using the two 13 mm spanners slacken both 8 mm nuts on the M8 cap set screw height limiter.
4. Dependent upon whether the ejector tip is protruding too far or too little, adjust the height of the cap screw and lock by tightening the two 13
mm nuts.
(Too much protrusion - increase height of set screw.)
(Too little protrusion - decrease height of set screw.)

HYDRAULIC SYSTEM
The Wintex 1000 utilizes a double acting hydraulic ram, which is housed inside the main chassis of the machine. Oil pressure is supplied and
controlled via an electronic solenoid operated directional control valve. This control valve has a manual override in the event of a failure.
The default pressure from factory is pre-set to supply 80 bar of pressure to the hydraulic ram on the upwards stroke and 50 bar of pressure on the
downwards stroke.
Less pressure is required on the downward stroke as the soil probe is designed to turn / drill into the surface to aid movement through the soil. A
higher pressure may cause damage to the machine if it were to strike an obstruction.
The pressure that the valve block is set to can be checked by observing the pressure gauge that is fitted to the valve block whilst the soil sampler is in
use.
The pressure can be adjusted on the valve block using the two turn screws and lock nuts. The top screw adjusts downwards pressure and the bottom
screw adjusts upwards pressure.
ALWAYS ADJUST THE UPWARDS PRESSURE FIRST.
*NOTE :
If the hydraulic ram will not move upwards or downwards it is worth remembering that although the machine may appear to have power, none of the
electronics or hydraulics will function if the supply voltage drops below 8 V.
PROXIMITY SENSORS
Three proximity sensors are fitted inside the main chassis of the machine and one in the top of the drilling head whose functions are to relay the
position of the drilling head back to the LOGO control unit which then decides which process to initiate next.
The sensors function in the following order:
Top sensor tells A port to supply oil to ram to go down.
Middle sensor does nothing on way down.
Bottom sensor tells probe to rotate once, and then port B to supply oil to ram to send mast up.
Middle sensors tell probe to keep rotating whilst going up and ejecting soil.
Top sensor tells valve block to stop supplying oil to ram to stop going up and waits for sensor in drill head to know when probe is in correct
position, then stop rotating.
Start again.
