SAFETY INSTRUCTIONS
IMPORTANT SAFETY ADVICE:
STOP. THINK. CALL 01224 722777
Safety First: Please read and fully understand the contents of this instruction manual, if you are in
any doubt whatsoever about the safe operation of this machine, please contact Charles J. Marshall
(Aberdeen) Ltd on Tel. [phone].
1. Guards - Ensure all guards are present and securely fastened in place.
2. Maintenance - Ensure the machine PTO and tractor is completely stopped and secure
prior to carrying out any maintenance.
3. PTO Shaft - Safety is important, if you are in any doubt of how to fit the PTO shaft,
please contact our service department.
4. Ensure that the pump is in the proper position for vacuum or pressure.
5. Ensure that the safety pressure relief valve is set and working correctly by lifting the top
round part, the pressure gauge should read no more than one bar - adjustment is required
if the pressure is higher than this.
6. Always apply the parking brake when the Tanker is to be left unhitched from the tractor.
7. Hydraulic Valve - Always check that the valve is open when pump is creating pressure
or vacuum.
8. Before undoing any hatch, ensure the tanker is depressurised completely.
9. Before entering a slurry tanker, make sure it has been properly ventilated, the pump is
running and that the person entering has a rope attached, which should be held by two
people. Never close the entry hatch with someone inside.
10. As some gases released by agitated slurry may be flammable, never smoke or hold up
naked lights in the vicinity of the tanker.
11. Extreme care is required if discharging slurry near power lines.

OPERATING INSTRUCTIONS
All Pumps fitted to Marshall Tankers, have unfortunately, to be subject to the Manufacturer’s
warranty terms which are that if a Pump has worked successfully for more than three hours
it cannot be regarded as being of faulty manufacture.
YOUR MARSHALL TANKER HAS BEEN DESIGNED TO GIVE YOU LONG &
RELIABLE SERVICE, ENSURED BY FOLLOWING THE INSTRUCTIONS BELOW.
General operating instructions:
1. Operating the tanker - Couple up the 6” hose either on the side or at the rear to the Bauer
coupling ensuring that the connection is airtight.
2. Open the appropriate valve, place the vacuum pump in the vacuum position then start the
PTO (at low engine speeds). Operators of tankers fitted with a hydraulic drive pump should
ensure both hydraulic hoses are connected to the tractor’s spool valves before engaging.
3. Watch the gauge on the front and take note of its reading as the hose becomes full, at this
point increasing vacuum is pointless as this is the point when the smallest amount of vacuum
is lifting the liquid.
4. By controlling the PTO speed you will be able to maintain this situation. (This greatly reduces
the risk of over filling and reduces the amount of froth created during loading).
5. When liquid becomes visible in the sight glass immediately shut the appropriate valve, shut
down the engine revs and when the engine is idling shut off the pump.
6. Uncouple the hose and change the pump position to pressure.
7. When emptying the tanker allow the pressure to build up then open the back rear valve -
never turn with the PTO running and always start and stop the pump at low engine revs.
Hertell Pump operating instructions:
1. Must be used in the 540 RPM PTO mode, the PTO speed must not exceed 350rpm.
2. There must be one oil drop, every one to two seconds, visible in the oiler. Remember this is
TOTAL oil loss, so MUST be checked and topped up daily to the top of the tank. Please note
the dip stick does not have a mark on it.
3. Check the oil level in the front gear box housing regularly.
4. Due to the weight and speed at which the main pump rotor rotates it is vital that the input
PTO speed is low when the pump is started or stopped.

To help prolong the life of the pump it is advisable, after every 25 working hours, to pass diesel
through it. This can be done by placing the pump in the pressure position and holding the container
of diesel up to the exhaust on the pump the diesel will be sucked up through the pump and will wash
out the entire pump.
1. KEEP THE PUMP TURNING for around 30 seconds then change the pump from pressure to
vacuum –note the foul diesel will pass out through the exhaust so some means of catching
this is advisable to enable you to dispose of this correctly.
2. Continue the pump running for around 30 seconds this greatly prolongs not only the pumps
life but coats the top shut off valve.
3. This procedure MUST only be completed when the pump is cold and DO NOT STOP THE
PUMP UNTIL the diesel has dispersed fully.
Bationie Pump operating instructions:
1. Must be used in the 540 RPM PTO mode, the PTO speed must not exceed 350rpm.
2. There must be one oil drop, every one to two seconds, visible in the oiler. Remember this is
TOTAL oil loss, so MUST be checked and topped up daily to keep the oil above the mark on
the dip-stick.
3. Check the oil level in the front gear box housing regularly.
4. Due to the weight and speed at which the main pump rotor rotates it is vital that the input
PTO speed is low when the pump is started or stopped.
To help prolong the life of the pump it is advisable, after every 25 working hours, to pass diesel
through it. This can be done by placing the pump in the pressure position and holding the container

2. Continue the pump running for around 30 seconds this greatly prolongs not only the pumps
life but coats the top shut off valve.
3. This procedure MUST only be completed when the pump is cold and DO NOT STOP THE
PUMP UNTIL the diesel has dispersed fully.

ALWAYS DISENGAGE PTO SHAFT WHEN TURNING.
NEVER OVERFILL TANK. TO AVOID THIS, CLOSE THE GATE VALVE WHENEVER SLURRY
IS VISIBLE IN THE SIGHT GLASS. THE OVERFLOW VALVE IS THERE ONLY FOR SAFETY.
MAINTENANCE INSTRUCTIONS
1. Hubs / Bearings must be greased regularly; we recommend they are checked after the first
fourteen days work, then six monthly thereafter.
2. Tyre pressure should be checked regularly (See page 10).
3. Wheel nuts should be checked when the machine is new, then after operating for one hour,
then one day and weekly thereafter. The same procedure applies if nuts have been removed
and replaced.
4. Check the tow hitch for wear and replace accordingly.
5. Lights should be kept clean and if not in use for some length of time, coating with some form
of oil spray is recommended.
6. Regularly check the top shut-off valve for damage or corrosion.
7. Keep Hydraulic 6” Valve Clean - This can be a cause of over filling problems as a poorly
adjusted unclean valve can allow air to pass when the tanker is being loaded causing vast
amount of unwanted froth.
8. Regularly check the slurry trap valve on the top of the tanker is moving freely and there are
no obstructions stopping its operation.
BRAKE ADJUSTMENT
Always adjust brakes with the spreader on
a completely level surface. This can be done
by loosening the nut behind the clevis, then
rotating the piston, adjustment will appear
from the ram. Remember to tighten the
locknut when completed.

Oil maintenance instructions:
1. Check the oil levels daily.
2. The front part of the pump is a gearbox which should be filled to the top of the small sight
glass, on the side, with SAE 90 (EP90/ISOVG220) oil.
3. The other oil is checked by removing the dip-stick on top of the pump and filling the oil
to the top, please note there is not a mark on this dip stick.
4. This is a TOTAL DISCHARGE OF OIL SO MUST BE TOPPED UP DAILY with SAE 20
(Straight20/ISOVG68) or similar (Do not use milking parlour oil).
5. The oil drip feed has to be set at one drop every two seconds when the pump is idling.
6. ENSURE THE PUMP IS PROPERLY LUBRICATED.
FITTING INSTRUCTIONS TO FIT ACTIVATOR TO GATEVALVE
1. Remove gland nut from the top of the gate valve, leaving the gland packing seals in place.
2. Remove dome part of gate valve from base by unscrewing the six Allen bolts.
3. Remove brass paddle and shaft assembly from the base of the gate valve, then remove
the paddle from the shaft.
4. De-tension activator spring completely by turning the top threaded rod in an anti-clockwise
motion.
5. When the tension is released totally, screw activator tightly into the domed top of the gate
valve, then using position 3 (locking nut) lock into position.
6. Replace brass paddle onto the bottom stainless steel shaft of the activator.
•Replace dome and activator assembly to the base of the gate valve making sure that the
gate valve gasket is in place and tighten the Allen bolts securely.
7. Re-tension the spring by turning the top threaded rod in a clockwise fashion, until the paddle
is seated firmly into the base of the gate valve.
8. Connect activator port to the tractor hydraulic system using 3/8” r1 hose.

GATE VALVE & ACTIVATOR MAINTENANCE INSTRUCTIONS
1. After frequent use the tension applied to the activator springs may loosen which will
cause the gate valve to not close properly.
2. This can be rectified by re-tensioning the springs accordingly.
3. Another problem which may arise with your gate valve/activator assembly is when
the gate valve does not fully open.
4. This is caused by the build-up of waste material being trapped and compressed in the
dome of the gate valve.
5. This can be prevented by removing the activator and top dome unit from the base
of the gate valve and cleaning out the dome.
6. N.B. Remember to slacken off all the tension from the activator spring when removing the
dome/activator unit, and then re-tensioning it when the unit has been bolted back together
again after cleaning. This will prolong the life of the activator as well as the gate valve.
Pressure valve adjustment
1. To adjust the pressure simply slacken the locking nut on the body of the valve then screw the
valve clockwise to increase pressure anticlockwise to decrease (NB maximum pressure should
be kept at 1barr / 15PSI).
