SAFETY PRECAUTIONS
Please read all of the safety and operating instructions carefully before using
this product. Keep these instructions in a safe place for future reference.
WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. Do not operate power products in explosive atmospheres such as in the
presence of flammable liquids, gasses or dust. Power products create
sparks which may ignite dust or fumes.
ELECTRICAL SAFETY
1. Do not abuse the electrical cable. Keep the cable away from sources of
heat, oil, sharp edges or moving parts. Damaged or tangled cables
increase the risk of electric shock.
PUMP SAFETY
1. DO NOT use this pump where there is a danger of fire.
2. DO NOT use to pump ANY liquid other than diesel, parafin and light fuel oil.
3. ALWAYS ensure the ON/OFF switch, is in the OFF (O) position, BEFORE
connecting to the battery. This is to avoid the possibility of arcing taking
place, thereby reducing the risk of fire.
4. Switch the pump OFF as soon as the task is complete.
5. Do not use the pump if the switch does not turn it on and off. Any power
product that cannot be controlled with the switch is dangerous and must
be repaired.
6. If necessary, have your pump repaired by a qualified person using
identical replacement parts. This will ensure that the safety of the product is
maintained.
ENVIRONMENTAL PROTECTION
1. Take care to ensure that if diesel fuel is spilt that it is cleaned away using
sand or treated with absorbent granules designed for the purpose.
2. Always make every effort to contain any spillage and prevent ingress into
the local water course.

ELECTRICAL CONNECTIONS
Before switching the product on, make sure that the voltage of your electricity supply is
the same as that indicated on the rating plate. This product is designed to operate on
230VAC 50Hz. Connecting it to any other power source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
could cause an electrical hazard
To ensure that the colours of the wires in the power cable correspond with the
markings on the terminals of your plug, proceed as follows.
•The wire which is coloured Blue must be connected to the terminal
which is marked Nor coloured Black.
• The wire which is coloured Brown must be connected to the terminal
which is marked Lor coloured Red.
• The wire which is coloured Yellow and Green must be connected to
the terminal which is marked E or or coloured Green
We strongly recommend that this machine is connected to the mains supply
via a Residual Current Device (RCD))
If in any doubt, consult a qualified electrician. DO NOT attempt any
connections yourself.
WARNING! READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE
MAINS SUPPLY.
WARNING! THE WIRES IN THE POWER CABLE SHOULD BE

CONNECTION & OPERATION
1. The pump can be installed in any horizontal mounting position and
mounted using screws of adequate size (not supplied) through the
mounting holes in the base.
2. If the fuel supply tank is located higher than the pump it is advisable to
install an anti-siphon valve to prevent the possibility of fuel leaks.
3. The pump should not be installed at more than 6m above the fuel supply.
4. Check the inlet and outlet ports and their threads are clean before
connecting the hoses.
5. Before connecting the delivery hose, partially fill the pump body with diesel
fuel to facilitate priming. Ensure hoses and tank are free of dirt particles.
6. Screw in either;
• A) the inlet and outlet hoses supplied or
• B) the inlet adaptors for use with 19mm hoses
NOTE: The infeed hose is connected to the side of the pump with the inlet filter
and the outlet hose to the side marked “OUT” on the pump body.
7. Connect the dispensing nozzle to the outlet hose.
• The hose and connections need to be completely air tight otherwise
air will be drawn in and reduce the flow.
8. Before connecting the delivery hose FOR THE FIRST TIME, partially fill the
pump body with fuel to facilitate priming. Ensure the hoses and tank are
free from contamination.
9. Ensure the ON/OFF switch is set to the OFF (O) position BEFORE plugging the
pump into the power supply.
10. Switch the pump on.
11. When starting for the first time, opening the dispensing nozzle will permit
evacuation of air and achieve quicker priming.
12. Always switch off the pump when finished dispensing.
13. Ensure the hose and inlet filter are clean as once clogged, pump
performance will quickly decline.
14. When finished pumping, switch off the pump. Do not allow the pump to run
dry for more than 30 seconds after discharge has stopped.
WARNING: DO NOT USE WITH PETROL OR ANY OTHER HIGHLY FLAMMABLE
LIQUID TO DUE TO THE POSSIBILITY OF SPARKING TAKING PLACE AND
CAUSING FIRE.
