SAFETY INSTRUCTIONS
Important Safety advice!
1. STOP
2. THINK
3. CALL 01224 722777
Safety First: Please read and fully understand the contents of this instruction
manual, if you are in any doubt whatsoever of the safe operation of this
machine, please contact Charles J. Marshall (Aberdeen) Ltd on Tel. 01224
722777.
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 AND RELIABLE SERVICE.
THIS CAN BE ENSURED BY FOLLOWING THE INSTRUCTIONS BELOW.
General Operating Instructions
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. 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. 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. 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). 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. Uncouple the hose and change the pump
position to pressure.
When emptying the tanker allow the pressure to build up in the tanker 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
Must be used in the 540 RPM PTO mode, the PTO speed must not exceed 350rpm.
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.
Check the oil level in the front gear box housing regularly.
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. 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. Continue the pump running for around 30 seconds this greatly prolongs not
only the pumps life but coats the top shut off valve.
This procedure MUST only be completed when the pump is cold and DO NOT STOP THE
PUMP UNTIL the diesel has dispersed fully.

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 8).
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.
5
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.
BRAKE ADJUSTMENT: Always adjust brakes with the tanker 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.
Maintenance Instructions - Oil
Check the oil levels daily.
1. 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 oil.
2. The other oil is checked by removing the dip-stick on top of the pump which should
always be kept above the mark. This is a TOTAL DISCHARGE OF OIL SO MUST BE
TOPPED UP DAILY with SAE 20 or similar. (Do not use milking parlour oil.)
The oil drip feed has to be set at one drop every two seconds when the pump is idling.
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
6. Replace brass paddle onto the bottom stainless steel shaft of the activator.
7. 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.
8. 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.
9. Connect activator port to the tractor hydraulic system using 3/8” r1 hose.
GATE VALVE AND ACTIVATOR MAINTENANCE
After frequent use the tension applied to the activator springs may loosen which will cause
the gate valve to not close properly. This can be rectified by re-tensioning the springs
accordingly. Another problem which may arise with your gate valve/activator assembly is
when the gate valve does not fully open. This is caused by the build up of waste material
being trapped and compressed in the dome of the gate valve. This can be prevented by
removing the activator and top dome unit from the base of the gate valve and cleaning out
the dome.
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
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).
Any other problems arising, please contact Charles J. Marshall (Aberdeen) Ltd service
department.
