This data sheet provides the information required on Section 6 of the Health and
Safety at Works Act 1974 as amended by Schedule 3 of the Consumer Protection
Act 1987.
The Polymeric compounds used on hose may contain materials that can migrate to
the surface from whence they could be transferred to the skin during handling. This
may cause skin irritation to persons who frequently handle hose. Persons who have
to handle the hose frequently are advised to follow good hygiene practices e.g. wear
gloves whenever practicable. Use barriers cream and wash hands after work before
eating, drinking or smoking.
With a few exceptions the polymeric materials used by Dunlop Hose Ltd are not easy
to ignite in bulk. However, when exposed to flame or to serious overheating they will
decompose liberating noxious or toxic smoke or fumes. Fire precautions should
recognise the hazards that may arise from indirect involvement in a fire as well as
the inherent fire risk of the individual products. Specialised advice on fire precautions
is available from local Fire Authorities and from Health and Safety Executive.
Hose may deteriorate in appearance and physical properties during storage
particularly if adverse storage conditions apply. BS3574 details the most suitable
conditions for storage. In summary, hose should be stored in an unstressed darkened
condition below 25°C and protected from moisture and air circulation. Exposure to
atmosphere containing high concentration of ozone, (eg near discharge from electric
motors) is to be particularly avoided. Hose should be stored away from direct heat
and contact with strong oxidising agents should be avoided.

COMMISSIONING AND OPERATING INSTRUCTIONS
The machine as delivered will be in two main assemblies.
A) The drive unit
B) The pump head complete with flexible drive shaft and coupling.
To assemble the flexible pump drive to the power unit, raise the latch knob on the
coupling housing on the engine and insert the coupling attached to the end of the
flexible drive. On releasing the knob the plunger should locate itself in the groove
in the plug-in connector. When connecting to a petrol or diesel engine it may be
necessary to rotate the engine crankshaft by means of a rope or handle starter at
the same time applying pressure to the coupling in order to obtain engagement.
Check the engagement by pulling on the coupling after releasing the latch knob.
The coupling must never be inserted into or removed from the housing with the
engine or electric motor running.
If the coupling is disconnected from the flexible shaft at any time, be sure to protect
all exposed ends from possible damage or entry of foreign matter.
When transporting flexible pump shaft assemblies, it is essential that they are never
coiled too tightly, likewise acute bends should be avoided when operating on site.
The recommended method of storing these flexible shafts is on timber racks so that
the shaft is kept straight and supported throughout its full length.

PUMP DRIVE UNIT –PETROL OR DIESEL
Carefully read the engine manufacturer’s instruction book before starting.
•Check oil level
•Turn fuel tap on
•Put speed control lever to tick-over
•If engine is cold, close the choke (petrol engines only)
•Turn engine switch to ON (1) position
Pull the starter rope toggle lightly until resistance is felt, then pull briskly using quick
short pulls. Do not pull rope to its full extent or allow toggle to snap back against the
engine. Return it gently to avoid damage. When engine is warm, open choke.
Position engine speed control lever to give required engine speed (usually full speed,
but see note below).
To stop engine, position the engine speed control lever to slow, and turn the engine
switch to off (0).
Turn the fuel valve to off.
NOTE: The governors of petrol and diesel engine drive units have been set at
2,750/2,850 rpm maximum. It is essential that the engine speed is not increased
over 3,000 rpm as this will induce stress which may result in failure of the pump
head or flexible shaft, and therefore may invalidate any warranty.
CHECK ENGINE SPEED.
With the coupling correctly inserted into the housing start the engine or switch on
the electric motor. During cold weather it is advisable to run petrol or diesel engines
for a few minutes before connecting to the flexible drive.

Avoid tight bends in the flexible drive shaft. Tight bends cause rapid wear of the
flexible core.
Check on a regular basis (weekly) that all joints on the flexible drive are tight.
Do not allow the coupling end of the flexible drive to lie in wet conditions on the
ground, as the entry of water to the bearings will cause rusting.
MAINTENANCE
Flexible Drive Shaft Type F535 –F545 –F550 –F565
(Refer also to Parts List)
The flexible drive shaft should be dismantled and recharged with grease every 500
working hours. As it is extremely difficult to keep accurate records, we would
suggest that the flexible pump be overhauled at set regular intervals. This will
ensure trouble free operation. The recommended grade of grease is Castrol BM2
or an equivalent.
Do not attempt to carry out the lubrication of the flexible shaft drive under site
conditions; this should always be carried out in a maintenance workshop.
When dismantling the flexible pump drive, first remove the plug-in connector (left
hand thread). The complete plug-in connector assembly may then be pulled away
from the flexible shaft.
Hold the bearing housing of the pump head assembly in a vice, then unscrew the
pump housing, complete with nose cap, in a clockwise direction (left hand thread).
Next unscrew the flexible drive outer case coupling from the bearing housing in a
clockwise direction (left hand thread).
Pull the outer casing away so as to expose the core coupling.

Hold the core coupling in a vice and unscrew the pendulum, complete with bearing
and oil seal etc, in an anti clockwise direction (right hand thread).
The inner flexible core can now be withdrawn from the outer casing.
Clean the flexible steel inner core an core couplings thoroughly with grease solvent.
Clean ends of outer casing with a cloth.
After thoroughly cleaning the complete flexible drive shaft, inspect the inner core
for any excessive wear due to rubbing action between the core and outer casing
spiral reinforcement; also for damaged and broken outer layer wires. If there is a
permanent bend in the outer casing we advise fitting a replacement, as this is liable
to cause damage to the inner core.
Regrease the first 12” – 18” (30 – 40 cm) of the inner core with Castrol BM2 grease.
Insert the greased inner core into the casing from the plug-in connector end.
Continue greasing the inner core and at the same time insert it into the casing.
Continue until the whole length of the inner core has been greased.
As the inner core is pushed through the outer casing, some of the grease will
naturally adhere to the inner walls of the casing. To ensure adequate lubrication,
it is advisable to draw out the core for approximately 6ft (2m) from the other end,
and regrease as the core is inserted back into the casing.
It is essential during the regreasing operation to keep dirt and grit away from the
component parts.
To re-assemble the flexible drive to the pump head, proceed as follows:
Pull out the inner core for about 4” (10cm) and screw the core coupling (right hand
thread) on to the exposed end of the pendulum, then screw the outer case coupling
into the bearing housing in an anti-clockwise direction (left hand thread). During this
operation, ensure not to damage the fine thread.
Should it be necessary to dismantle the coupling, proceed as follows:
Unscrew main shaft head and remove internal circlip.

Press out the main shaft complete with bearings etc, by means of an arbour or fly
press. When carrying out this operation support the large diameter of the housing and
apply pressure to the small end of the shaft.
Next remove the circlip and withdraw the key retaining collar, the key itself can now
be withdrawn from its locating keyway.
The bearings and spacer can now be pressed off the main shaft.
Check the condition of the two ball bearings, and replace if necessary.
Reassembly is generally the reverse of the above procedure.
After fitting the ball bearing and spacer the driving key can be inserted in the keyway
and the key-retaining collar replaced to hold the key in position.
Fit the circlip to retain the collar.
Fill the space between the two bearings with Castrol BM2 grease.
Press in the bearing sub-assembly into the housing until the inner bearing is in
contact with its locating shoulder.
Refit internal circlip and screw on main shaft head.
When screwing on the plug-in connector to the flexible drive shaft, be sure that the
core coupling keyway is fully engaged with the internal key of the main shaft.
