Frequently Asked Questions - TG920ES Texas

How to start the TG920ES engine?

Open the fuel valve. Turn the choke lever to the left (cold engine). Turn the throttle grip fully to the left. Set the ignition switch to ON. Pull the starter cord slowly until resistance is felt, then pull hard and quickly. Do not release the cord; rewind it slowly. Adjust the choke to obtain a steady speed.

Which engine oil to use and how much?

Use SAE 30 or 10W-40 oil depending on the season. The oil capacity is 1.1 liters. Check the level with the dipstick without screwing it in, engine horizontal.

How to drain the engine oil?

Run the engine for 5 minutes to warm the oil. Place a container under the drain plug (fig. 6.1). Unscrew the plug and let the oil drain. Screw the plug back on, then fill with 1.1 L of new oil. Dispose of used oil at a recycling center.

How to clean the air filter?

Remove the nut (fig. 8A) and the cover (fig. 8D). Remove the nut (fig. 8E) and the gasket. Clean the air filter (fig. 8G) by tapping gently or using compressed air. Do not use a brush. Clean the foam element (fig. 8H) with gasoline or kerosene, let it dry, then soak it in fresh oil and squeeze. Reassemble in reverse order.

Which fuel to use?

Use unleaded gasoline with at least 95 octane. The tank capacity is 6.5 liters. Do not overfill; a level indicator is present.

What safety precautions to observe?

Exhaust gases are toxic: use the engine outdoors or in a well-ventilated area. Do not touch the exhaust or engine block during operation (burn hazard). Stop the engine before refueling. Do not use after consuming alcohol or drugs.

What is the spark plug gap?

The gap should be 0.7 to 0.8 mm. Use a special wrench to loosen the spark plug and a wire brush to clean it. Check the insulation before reassembling.

What to do if exhaust gases are black?

Black exhaust gases indicate that the load is too high or the engine is incorrectly adjusted. Stop the engine, adjust it, or contact an authorized workshop.

How to store the engine for a long period?

Let the engine run until the fuel is exhausted. Loosen the carburetor drain screw and drain the remaining fuel. Remove the spark plug, pour a tablespoon of oil into the cylinder, then reinstall the spark plug without the protector. Pull the cord until resistance to close the valves. Apply a thin coat of oil to prevent corrosion.

How to transport the engine safely?

To prevent fuel or oil leaks, place the engine horizontally during transport.

2. Starting

PROCEDURE

1. Open the fuel tap.
2. Turn the choke lever to the left by a cold engine.
   Note: By a hot engine choke is not required.
3. Turn the engine's gas control completely to the left, thereby full gas is applied. (If the engine is mounted on a machine with cable-regulated gas, full gas is given).
4. Turn the throttle cable to "start position".
5. Pull the recoil starter gently until you feel resistance in the rope. Then pull quickly and energetic. Do not at any time let go of the recoil starter but slide it gently back and pull again.
6. Regulate the choker until the engine is running smoothly.

See fig. 1, 2, 3, 4.

3. Operation

OPERATION

1. When the engine has been started move the choke gradually to the right.
2. Adjust the gas to the requested speed.

See fig. 2.

NOTE

Please observe the following during operation.

• Exhaustion must not be black. If the exhaustion is black the load is too high or the engine has not been adjusted correctly.
• Unpleasant sound and vibration.
• If these appear turn off the engine and adjust it. Contact your dealer

4. Stopping the engine

PROCEDURE

1. Turn the gas control at the "low" position and engine will stop running.
2. Turn the fuel tap to the "off" position

See fig. 3.

OIL
Use the correct oil for the specific time of year.

SAE 30 or 10W-40
SAE 30 Art.no 90306506

OIL CAPACITY

• Always check the oil level when the engine is placed in a horizontal position.
  • Always check the oil level without fastening the oil stick.

See fig. 5.

1.1 Litre

CHANGING OIL

Change oil in accordance specification with the manual for the machine.

1. Let the engine run 5 minutes, so the engine is hot.
   Warm oil liquefies, which makes it easier to drain the oil.
2. Unscrew the drain plug (Fig 6.1) and let the warm oil run out of the engine.
   Remember to keep an appropriate container ready.
3. Attach the drain plug and fasten.
4. Add new oil to the engine. Remove the dipstick and pour the correct amount of oil (see capacity above).

Please dispose the used engine oil environmentally correct. We suggest that you keep the used oil in a sealed container and dispose at your recycling center or service station for reclamation. Do not throw it in the waste; pour it on the ground; or down a drain.

AIR FILTER

The air filter should be inspected and cleaned regularly. If the filter has not been cleaned for a long period of time, this will influence the engine's combustion and engine power.

1. Remove the nut (Figure 8.A) and remove cover (Fig 8.D).
2. Remove the nut (Fig 8.E) and remove the gasket (Figure 8.E)
3. Clean the air filter (Fig 8.G) before being removed.
4. Now carefully remove the air filter (Fig 8.G) out of the foam element (Fig 8.H)
5. Inspect and remove the dust from the air filter by tapping the element easily a few times. Alternatively run compressed air through the inside of the filter.

Warning! Never try to brush away the dust. A brush will only push the dust further into the element. Replace the air filter if it is very dirty.

1. Inspect and clean the foam element (Fig 8.H) with petrol or kerosene
2. Wrench the foam element (Fig 8.H) and let it dry. Hereafter soak the element in fresh oil, squeeze any redundant oil out of the element.
3. Clean the lid (Fig 8.1)
4. Reattach the foam element (Fig 8.H) and the air filter (Fig 8.G) and fasten.
5. Please note that all parts are assembled correctly. (See Fig. 8)

IMPORTANT: Under no circumstances should oil be applied on the air filter (Fig.8G).

QUESTION

If you are in doubt that the air filter is mounted correctly, please contact your dealer.

ASSEMBLY

1. Attach the filter (Fig. 8 G and H) on the lid (Figure 8.I). Insert the gasket (Fig. 8.F) in the assembled filter.
2. Secure with nut (Fig 8.E.). Note: It is important that it fasten tightly.
3. Insert the cover (Fig 8.D) Mount gasket and washer (Fig 8.B and C) then fasten with a nut (Fig. 8.A).

Ensure that all parts are correctly fitted, this is to prevent that no air will get into the engine.

8. Sparking plug

PROCEDURE

• Remove the sparking plug cover.
• Brush off dirt from the sparking plug.
• Use a sparking-plug wrench to loosen the sparking plug.
• Inspect if the isolation is intact.
• Clean the sparking plug with a steel brush.
• Measure the electrode distance; make sure not to damage the electrode.
• The distance should be: 0,7 – 0,8 mm
• If the sparking plug is okay, put it back in its place.
• Put the sparking plug cover back in its place.

9. Transport and storage

TRANSPORT AND STORAGE

Transport

- To avoid any spillage of fuel and oil is it important that the engine is placed horizontal during transport.

Storage

• Let the engine run till it stops.
• Loosen the drain screw on the carburettor and drain the remaining fuel.
• Reinstall the drain screw, and mount the fuel tube.
• Keep the old fuel in an approved container.
• Remove the sparkplug and poor 1 tablespoon of oil into the cylinder, mount the sparkplug.
• Do not mount the sparkplug cap. Pull the sparking cord, until there is resistance. This will close the valves and protect them from rust.
• Protect the oil with a thin layer of oil to avoid rust.

10. Maintenance

NOTE

• The purpose of maintenance is to keep the engine in its best possible shape.
• Repairs should always be carried through by an authorized dealer.
