Features

The Extol® Craft 414502 and 414503 motor jet pumps are intended for pumping clean fresh water from underground sources, e.g. ponds, streams, fire protection reservoirs, pools, etc. for use in domestic gardens and recreational areas, namely in areas without electrical energy. Thanks to its lightweight and compact dimensions, the pump is portable and easy to store. The pump is equipped with variable flow control of the pumped fluid and is easy to operate. The pump is not designed for pumping muddy water and sediments, i.e. fluids from sewage tanks, flooded trenches with muddy water, and water containing abrasive particles such as sand, i.e. the pump is not a substitute for a sludge pump.

Technical specifications

OTHER PARAMETERS

1. The power (flow rate) of the pump is divided between the suction depth and the delivery height. To achieve the maximum delivery height, the suction depth must be as small as possible. To achieve the maximum delivery flow rate at the outlet, the suction depth, and the delivery height must be as small as possible. The delivery flow rate of the pump declines proportionately with the increasing length of the hose and the viscosity of the pumped liquid, with the increasing height difference between the position of the pump and the hose end, with the diameter and resistance of the hose, with declining water temperature.
2. The declared suction depth of 8 m is achieved on pump 414502 with the use of a check valve on the suction hose that can be purchased at a store selling pump equipment. The reason for this is the greater weight of the water column in the hose that acts to counter to the suction strength of the pump when there is no check valve present. This valve can be purchased in combination with a suction strainer. Without the use of a check valve, the suction depth is approximately 3 m, which is sufficient for pumping water from normally accessible surface water sources. Pump 414503 does not require a check valve to achieve a suction depth of 8 m, however, the flow rate of the pumped fluid will be lower. In the event that it is necessary to increase the volumetric flow rate, use a foot valve (check valve with an inlet strainer).
3. An equivalent of spark plug Torch L6 is for example NGK BM 6A or Brisk P17; An equivalent of spark plug NHSP LD L7T is for example NGK 4921 or Champion CJ7Y.
4. The sound pressure and power level were measured according to EN ISO 20361.

Before putting the pump into operation

ATTENTION
Carefully read the entire user‘s manual before first use and keep it with the product so that the user can learn about it. If you lend or sell the product to somebody, include this user‘s manual with it. Prevent this user‘s manual from being damaged. The manufacturer takes no responsibility for damages or injuries arising from use that is in contradiction to this user‘s manual. Before using this appliance, first, acquaint yourself with all the control elements and parts as well as how to turn it off immediately in the event of a dangerous situation arising. Before using, first check that all parts are firmly attached and check that no part of the equipment, such as for example safety protective elements are damaged or incorrectly installed also check the quality and suitability of the suction and delivery hose that you wish to use for pumping. Do not use equipment with damaged parts and have it repaired at an authorized service center for the brand – see chapter Servicing and maintenance.

CONNECTING THE SUCTION AND DELIVERY HOSES

• It is possible to use standard hoses, fittings, and gasket seals.
• Hose connectors for attaching the suction and delivery hoses and the hose clamps necessary for attachment are supplied with the pump.
• The hoses must the reinforced type so that they are not deformed during suction or ruptured during delivery. These hoses should be rated for an operating pressure of approx. 6 bar with an emergency pressure rating above 15 bar.
• The suction hose should be as short as possible so that the weight of the water column is as small as possible. The performance of the pump will then be improved by either a higher delivery or flow rate.

ATTENTION
Always insert an inlet strainer onto the entry into the suction hose (fig. 1 C, position 18). The inlet strainer prevents sucking larger mechanical particles and objects into the hose and thereby prevents the hose from clogging or seizure the pump. In the event that pump 414502 is used for a suction depth in the range of 3 to 8 m, install a foot valve at the entry to the suction hose, see chapter Technical specifications, paragraph 2). Pump 414503 does not require a check valve to achieve the maximum suction depth of 8 m, however, the flow rate of the pumped fluid will be lower. To increase the flow rate, it is nevertheless possible to use a foot valve.

• The delivery hose should also be as short as possible as the greater the length the lower the flow rate.

Install a hose connector onto the thread of the suction and delivery fitting in sequence 1-4 shown in fig. 3, i.e.: gasket – hose connector over which a cap nut is placed, which will then hold the hose connector on the male/delivery fitting. Then, on to the installed hose connector, slide on the hose with a hose clamp, and firmly tighten it so that the hose resists the water pressure at the outlet and so
that air is not drawn in at the inlet due to leaks around the house.

ATTENTION
Do not use reduction fittings to connect hoses of smaller diameters than the supplied hose connectors. This would pressurise the system.

PRIMING THE PUMP HOUSING WITH WATER

ATTENTION
Before every use of the pump, always fill the pump housing with water. Otherwise, the sealing element will be damaged due to excessive overheating caused by “dry” running. In the event that the pump runs “dry”, immediately shut off the motor and allow the pump housing to cool down, and only then pour in the water.

1. Remove the pump housing priming hole bolt (fig. 1B, position 16; fig. 2B, position 14) and completely fill up the pump housing with water.
2. Then screw the bolt back on and tighten firmly.

MIXING THE FUEL MIX AND FILLING UP WITH FUEL

FUEL

ATTENTION

• The pump is equipped with a two-stroke combustion motor that uses a mix of lead-free petrol and two-stroke motor oil mixed at a petrol: oil ratio of 40:1. When fuel is poured for the first time into the fuel tank of a new pump that has not yet been used, use petrol: oil ratio of 35:1 in order to lubricate the system. The next time that the fuel tank is filled, use petrol: oil ratio of 40:1. Never use a mix that is mixed at a different ratio because a greater amount of oil in the petrol would cause problems with starting, would soil the spark plug, carbonize the exhaust and significant emissions of exhaust fumes would result. On the other hand, an insufficient amount of oil would lead to motor damage due to insufficient lubrication. Using pure petrol without oil or a poorly mixed fuel mix will damage the motor; a free warranty repair cannot be claimed for such damage.
• To mix your fuel mix, use quality lead-free petrol e.g. RON 95, 98, and a quality motor oil for air-cooled two-stroke motors.
• Never use motor oil with a recommended mixing ratio of 200:1.
• The use of poor-quality fuel or oil negatively affects the starting, operation, and performance of the pump‘s motor.
• Never use a fuel mix older than 90 days. Petrol absorbs water, aerates, and loses its quality over time, which could cause problems with starting up or could have a negative effect on the operation of the motor. Pour the old fuel mix out of the tank and take it away for ecological disposal before pouring in a new mix.

MIXING THE FUEL MIX
When filling up the fuel tank of a pump that has never been operated, mix the fuel and oil at petrol: oil ratio of 35:1, for example in the supplied plastic measuring bottle with a volume scale. After adding oil to the petrol, thoroughly stir up the prepared mix to ensure that the oil does not sit at the bottom of the measuring bottle. When filling the fuel tank of a pump that has already been in operation, prepare petrol: oil mix of 40:1.

In the table provided below, this ratio is calculated for mixing several liters of the fuel mix. Petrol: oil ratio of 35:1 for the first fill-up of the fuel tank: Mix 1 liter of petrol with 29 ml of two-stroke oil.

TABLE OF VOLUMETRIC RATIOS OF PETROL AND OIL FOR PREPARING SEVERAL LITRES OF FUEL MIX

Petrol: oil ratio of 40:1

Thoroughly shake the mix in the bottle to ensure that both components mix together well.

FILLING UP WITH FUEL

• Fuels are poisonous. Therefore, prevent these substances from coming into contact with skin and do not digest them. When handling fuels, use protective aids,
  i. e. gloves and protective glasses. Petrol is absorbed through the skin into the body. Fill the fuel tank in well-ventilated locations. Avoid breathing in the vapors. They are harmful to health.

• Fuels are flammable and ignite easily, therefore, do not smoke when handling fuels or use an open flame or sources of sparks. Do not refill fuel in the presence of radiant heat sources and while the pump motor is running. Turn off the motor and allow it to cool down before refilling it.

Screw off the fuel tank cap and through the fuel, tank strainer pour in the mix prepared in an above-described manner

• In model 414503, the strainer is inserted inside the neck of the fuel tank.
• With model 414502 it is necessary to pour fuel into the fuel tank using a funnel fitted with a strainer. The strainer will remove any potential mechanical particles contained in the fuel, which could clog the pump‘s fuel system. Do not overfill the fuel tank to prevent fuel from spilling out of the fuel tank when handling the pump.

Firmly tighten the fuel tank cap after refilling of the fuel

• If any fuel was spilled, wipe it away before starting the motor.

Starting the pump‘s motor

The pump must not be operated in enclosed rooms, in rooms with exhaust fume extraction ducts not approved by relevant safety authorities, or in areas with poor fume extraction, e. g. outdoor trenches, where fumes remain at ground level and are not removed efficiently. The pump must not be operated in an environment with an explosion hazard.

ATTENTION

• Before starting up the pump‘s motor, place the pump on a stable and even surface and ensure that the pump housing is primed with water, that the suction hose is submerged in water and that the delivery hose is located in its intended location. Secure the end of the delivery hose before starting the pump to ensure that it is not lashed out as a result of the pressure impulse.
• Ensure that flow is unimpeded along the entire length of the suction and delivery hose, i.e. by a kink, etc. In the event that the hose is in contact with sharp edges, place suitable protection between the hose and the sharp edge at the contact point.

Check that all connections are properly attached and secured.

1. Set the flow regulation lever (fig. 1A, position 8, fig. 2A, position 14) to approximately half the maximum. The position of the flow regulation lever for minimum and maximum speed is the same for both models.
2. On model 414502, use a finger to press the fuel priming pump 2x to 3x (fig. 1B, position 11).
3. Do not unnecessarily press the primer pump more times so as not to flood the carburetor with fuel.
4. Model 414503 is not equipped with a fuel priming pump, however, it is necessary to open the fuel supply to the carburetor by turning the fuel valve (fig. 2A, position 9) from the horizontal position (from position „OFF“) downwards to the vertical position (position „ON“).
5. Set the chock lever (fig. 1A, position 7, fig. 2A, position 10) to position „CLOSE“ – upwards to the position of the symbol.
6. Hold the pump by the handle and step on the part of the stand on the side of the manual starter and pull on the pull cord of the manual starter. Then firmly pull on the starter handle and slowly bring it back with your hand.
7. Do not allow it to rewind uncontrollably on its own as this could damage the starting mechanism. If the motor does not start up, repeat the movement. If you are unable to start the motor, proceed according to chapter Cleaning and maintenance.
8. If the motor shows signs of starting up but is choked, try setting the choke lever to position „OPEN“ – downwards to the position of the symbol. If not, leave the choke lever in the position „CLOSE“. Needs to be checked with a practical test. After starting the motor, after a while, gently move the choke lever to the position „OPEN“.
9. Set the power/rpm regulator to the position between the minimum and maximum – depending on the required flow rate respecting the deli-very height and suction depth, see fig. 5.

STARTING A WARM ENGINE
When starting an already warm motor, on model 414502 it is not necessary to inject fuel into the carburetor using the priming pump. Likewise, it is usually not necessary to set the choke lever to the position „CLOSE“, however, it is necessary to make a practical test.

Turning off the pump‘s motor

1. Set the flow rate/speed regulator to minimum power.

2. Turn off the pump‘s motor by pressing the button (fig. 1B, position 12; fig. 2A, position 12).
    ATTENTION

3. After finishing using pump 414503, always shut off the fuel supply to the carburetor by setting the fuel valve lever to position “OFF”. When handling the pump, e.g. when transporting it, there is a risk that additional fuel will inadvertently enter the carburetor or cylinders of the motor, which will result in not being able to start the pump and will need to be repaired at an authorized service center.

ATTENTION
In the event that it is necessary to quickly turn off the motor, first press the motor shut-off button and then perform the other steps.

Putting the pump out of operation.

FLUSHING OUT THE PUMP HOUSING

• After pumping water out of a pool that contains chlorine or pumping dirty water, flush out the pump and hoses, if necessary, with clean water to remove any sediments in the pump housing.
  • In the event of greater soiling, e.g. after pumping out a garden pond in which there are Microsemiments of decayed biological material, clean out the pump housing including the hoses by drawing clean water from a prepared container with the pump motor running.
  • In the case of pumped pool water containing chlorine or slight soiling, it is possible to turn off the pump‘s motor, disconnect the hoses and pour in clean water through the filling opening of the pump housing and then drain this water from the pump housing by unscrewing the drain hole bolt (fig. 1B, position 13‘ fig. 2B, position 18) by tilting the pump to ensure that all the water exits the pump housing. After draining the water from the pump housing, screw the bolt back on.

ATTENTION

• Water must always be drained from the pump housing by removing the drain bolt and tilting the pump before storage regardless of whether the water is clean or not. Particularly when the pump is stored at temperatures below 0°C, water in the unemptied pump housing will freeze and damage the sealing elements and the pump system.

Cleaning and maintenance

ATTENTION

• Before commencing maintenance, turn off the motor and allow it to cool down.
• To ensure optimal operation of the pump, it is necessary to carry out regular inspections of the pump according to the maintenance plan table below.

 | After every use| Every 3 months

or after 50 hours of ope- ration

| Every 6 months

or after 100 hours of ope- ration

| Every year or after 300 hours of operation

• x1) In a dusty environment, clean the filter more frequently
• x2) These tasks may only be performed by an authorized service center for the Extol® brand (you can find the service center locations in the user‘s manual).
• x3) The carburetor of pump 414502 may only be purged by an authorized service center for the Extol® brand because it is necessary to work on the internal parts of the carburetor.

On model 414503, the user can purge the carburetor themselves by screwing out the purge bolt, see below. In this case, it is not necessary to work on the internal parts of the carburetor.

ATTENTION
Replace old parts only with original components supplied by the manufacturer.

CLEANING THE AIR FILTER
A clogged air filter prevents air from flowing to the carburetor. For this reason, it is necessary to regularly clean the filter. Never start the pump‘s motor without a clean filter. This would damage the carburetor.

1. Remove the air filter cover and take the air filter out of its housing.

2. Submerge the filter in a soap solution and then wring it out. Repeat the procedure several times. Finally, submerge the filter in soapy or detergent water and wring it out. Do this several times to thoroughly wash the cleaning agent out of the filter.
   ATTENTION

   • Never use flammable fluids to clean the air filter. Dust may become charged with static electricity and this could result in a fire if flammable fluids were used.
   • If it is not possible to clean the filter or if it is damaged, replace it with a new one. Only use original filters from the manufacturer, because low air permeability in the event of an excessively dense filter will negatively affect the motor‘s operation. High filter permeability may result in a low filtration effect and lead to damage to the carburetor.

3. Allow the filter to dry thoroughly.

4. Then submerge the filter in clean motor oil and wring out any excess oil. Use water-resistant gloves. Oil is absorbed through the skin into the body and is damaging to health.

5. Put the filter back in its original location, firmly attach the cover, and screw it in.

MAINTENANCE OF THE SPARK PLUG

In order to achieve problem-free operation of the pump, the spark plug must be correctly seated and clean from deposits.

1. Remove the spark plug connector from the spark plug.

2. Screw out the spark plug using the included spark plug key.

3. Mechanically clean away any deposits on the electrodes, e.g. using sandpaper or a steel brush. If necessary, adjust the clearance between the electrodes to 0.6 – 0.7 mm using pliers.
   If the spark plug is very dirty, replace it.

   • We recommend using quality spark plugs, e.g. NGK or Brisk, etc. because poor quality spark plugs may cause problems with starting up. An equivalent of the spark plug that is supplied with the product as specified in paragraph 3) in chapter Technical specifications.
   • A heavily soiled or worn-out spark plug has a negative effect on the starting and running performance of the pump‘s motor.
   • The speed at which the spark plug is soiled, starting and motor performance is significantly affected by the quality and age of the fuel as well as the mixed-in motor oil.

4. Check the sealing ring on the spark plug.

5. Screw the spark plug on all the way by hand. Then use a spark plug key to tighten it by:

   • 1/2 rotation on new spark plugs
   • 1/4 rotation on already used spark plugs.
   • Never fully tighten a spark plug „to maximum“, this would damage the sealing ring.

6. Put the spark plug connector back on the spark plug so that it is seated correctly, otherwise, the motor will not start up.

PURGING THE CARBURETTOR

ATTENTION

•  The carburetor of pump 414502 may only be purged by an authorized service center for the Extol® brand because it is necessary to work on the internal parts of the carburetor.
• In model 414503, the user may purge the carburetor themselves because it is not necessary to work on the internal parts of the carburetor.

Purge the carburetor in a well-ventilated area and prevent access to an open flame or heat. Wear waterproof gloves when purging the carburetor.

1. Shut off the fuel supply to the carburetor by closing the fuel valve.
2. Remove the bolt on the underside of the carburetor (fig. 2A, position 7) and allow the dirty fuel to drain into a prepared container.
3. It is possible to open the fuel valve for a short moment to flush out the carburetor and then close it again.
4. Ecologically dispose of the dirty fuel.

CLEANING THE PUMP HOUSING
If the pump housing is clogged or the impeller is blocked, it is necessary to screw out the front side of the pump housing. We recommend that this task is given to an authorized service center because for the pump to run properly, the sealing elements must be correctly reinstalled without being damaged when returning the cover because an incorrectly attached cover will damage them. This type of repair does not constitute a warranty repair.

TROUBLESHOOTING

If a problem arises when using the pump, attempt to remedy it according to the following table. If you are unsuccessful in remedying the problem, please contact the vendor from whom you purchased the pump, who will organize its repair at an authorized service center for the Extol® brand, or you may hand it over to an authorized service center directly (You will find a list of service centers at the website in the user‘s manual).

Safety instructions

• Never start the equipment in an enclosed room or under conditions of insufficient cooling and access to fresh air. This also applies when using the pump in trenches, shafts, and outdoor holes, where exhaust fumes fill up such areas because they are denser than air and therefore are not well ventilated out of such areas. This may result in the poisoning of persons working in these areas. Exhaust fumes are poisonous and contain toxic carbon monoxide, which is a colorless and odorless gas that may result in loss of consciousness when inhaled and possibly also death. If the pump is located in ventilated rooms, it
  is necessary to ensure perfect extraction of exhaust fumes, continuous supply of fresh air and to maintain safety rules for fire prevention.

• Petrol is flammable and poisonous, including its vapors. Therefore, prevent fuel from coming into contact with skin, breathing in vapors, and ingesting it. Handle petrol and refill the fuel tank in well-ventilated areas to prevent inhaling petrol vapors. While performing such tasks, use suitable protective aids to prevent skin contact and potential spillage.
  When handling petrol, do not smoke or handle an open flame. Avoid contact with sources of radiant heat.
  Do not refill petrol while the pump is running. Turn off the motor and wait for all parts to cool down before refilling the tank.

• Do not allow anybody to operate the pump without prior instruction. Prevent the equipment from being operated by a person that is physically or mentally unfit, under-aged, incapacitated under the influence of drugs, medication, alcohol, or exhausted. Prevent children from using the pump and ensure that they do not play with it.

• The motor and exhaust are very hot during operation and long thereafter and may cause burns. Therefore, heed all warnings in the form of symbols on the machine. All persons (children in particular) and animals must therefore remain at a safe distance from the equipment. Allow the pump to cool down before transporting or storing it.

• Heed all instructions on labels located on the pump.

  • Never start the pump in an enclosed room without a sufficient supply of fresh air and ventilation. Exhaust fumes are poisonous, so do not inhale them.
  • Do not start the pump in an environment where there are flammable and explosive substances and at distances closer than 1 meter to other objects.
  • To prevent a fire hazard, do not place any items on the hot parts of the pump.
  • Use hearing protection when remaining in the vicinity of the pump. The acoustic power level exceeds 85 dB(A), which may cause damage to hear after extended exposure.
  • Do not leave the pump running with the pressurized water outlet closed.
  • If there is no pumped water entering or leaving the pump, turn it off immediately. Running the pump „dry“ leads to burning the sealing elements in the pump housing.
  • Do not use the pump for pumping fluids other than clean fresh water. Pumping of chlorinated pool water is permitted, however under the condition that the correct dosage of chemical agents for domestic pools is adhered to according to the manufacturer’s instructions, which will prevent damaging the pump by aggressive fluids. After pumping chlorinated water, the pump housing must be flushed out with clean water. The pump must not be used to pump salt water, flammable, thick, or aggressive fluids, foodstuffs, and water containing aggressive particles, e.g. sand, soil, etc. Abrasive particles will rapidly wear out the pump and reduce its performance.
  • The pump may be used to pump fluid with a maximum temperature of 35° and a minimum temperature of 0°C. Water must not contain any ice or crushed ice.
  • Always position the pump on a firm even surface so that it does not tip over during its operation. Do not tilt it by more than 15° from the horizontal position. In the event of a greater angle, there is a risk of fuel spilling from the fuel tank.
  • Before starting the pump, make sure that you know how to shut off the motor as quickly as possible if necessary.

Waste disposal

• Throw packaging materials into a container for the respective sorted waste.
• Do not dispose of unserviceable commodities in household waste, but dispose of them in an environmentally safe manner. According to Directive 2012/19 EU, electrical appliances must not be thrown out with the household waste but rather handed over for ecological disposal at an electrical equipment disposal point. Fuel must be removed from the product before it is disposed of. You can find information about collection points and collection conditions at your local town council office.
• Handover unused fuel in a container for ecological disposal at determined collection points.
