1. First Fuelling
The engine will need to be filled with oil.
1. Use unleaded petrol for the fuel tank. 2. Use SAE10W-30 oil for the oil tank. SAE10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range. 3. Add in a well ventilated place. 4. Do not add too much oil or unleaded petrol. The oil and petrol should not exceed the neck of their separate filling ports. If any oil or petrol spills, wait until the fuel is removed or volatilizes completely and then restart the engine.
2. Operational Instructions
1. Press the Start/Stop switch to START. 2. Set the choke control to the OFF position. 3. Repeatedly press the primer bulb until you see the fuel flow through the transparent hose from the fuel tank to the carburetor. (Close the air vent when the engine is in the state of cooling, and only open the air vent when the engine is heated). 4. Set the machine upright and hold the operation handle with one hand while quickly pulling the recoil starter. The engine should start after a few pulls. Open the air vent completely once the engine has started, and move the choke control to the ON position. 5. Carry out up to 5 minutes of idle operation to warm up the machine. 6. Once the engine is warmed up, squeeze the throttle lever and hold the handle grip firmly as you slowly lower the Post Driver and make contact with a post. 7. To stop, release the throttle and turn the Start/Stop switch to STOP.
3. Driving in a Post
1. Stand the post in the required position by lightly tapping the post into the ground with a hammer. Ensure that the post is stable enough to take the weight of the Post Driver.
Doing this step in batches will save time. You can use a guide wire to maintain a straight fence line. 2. Lift the Post Driver over and on to the post. Ensure that the post is in a vertical position and the post driver is on a parallel plane to the post. 3. Ensure the operator maintains a stable standing position and keeps their body weight balanced. 4. Pull down on the Post Driver with 5-10kg of downward force. This ensures that the internal hammer mechanism is engaged in the correct operating position, and reduces unexpected movement while driving. 5. Gently pull the throttle trigger until the hammer action is felt. 6. Once the post can be seen as being driven into the ground, fully depress the throttle trigger and drive the post to the desired depth. 7. If the post does not drive into the ground, cease driving and move the post along and try again. 8. Once the desired depth has been reached, release the throttle so the engine is idling and the hammer action has stopped. 9. Move to the next post and repeat. 10. To stop the machine, press the Start/Stop switch to STOP.
4. Maintenance: Spark Plug
1. The correct air gap should be 0.5mm. 2. Stop the engine and allow it to cool. Using the multi-tool remove the spark plug. 3. Clean any dirt from around the spark plug. Do not let any dirt enter the cylinder. Re-gap the spark plug using a Feeler Gauge, replace and tighten.
5. Maintenance: Air Filter
1. Check the air filter regularly. 2. Clean the air filter with warm water and detergent, and then dry it thoroughly. 3. Replace the filter if it is damaged. 4. The air filter sponge should be replaced after 36 hours of work.
6. Maintenance: Fuel Filter
If the fuel filter is clogging, the speed of the petrol driver will slow and it will have a weak impact upon posts. When cleaning the fuel filter, clean the fuel tank.
7. Maintenance: Carburetor
The fuel tank and carburetor are usually left with residual oil. This will eventually plug the oil line which will stop the engine from working. Therefore, if the machine has not been in use for a long period of time, be sure to take the fuel completely out. Do this by pressing the carburetor primer bulb to drain the oil.
8. Maintenance: Impact Cylinder
After working for an accumulated 50 hours, fill the impact cylinder with grease.
9. Maintenance: Oil Compartment.
Add oil into the oil compartment.
10. Maintenance: Oil Change
Make sure you change the oil regularly as there are many parts in the engine that need to be lubricated. Running the engine with a low oil level can cause engine damage.
1. Drain the used oil when the engine is warm. Warm oil drains quickly and completely. 2. Place a suitable container below the engine to catch the used oil. 3. Remove the oil filler cap/dipstick and drain the oil into the container by tipping the engine toward the oil filler neck. Please dispose of used motor oil in a manner compatible with the environment. Do not throw in the bin, pour on the ground, or down a drain. 4. With the engine in a level position, fill to the bottom edge of the oil fill hole with the recommended oil. 5. Reinstall the oil filler cap/dipstick securely.
11. Maintenance: Muffler
Regularly remove dirt on the inlet and outlet of the muffler.
12. Maintenance: Cylinder Heat Sink
Regularly remove dust to ensure cylinder cooling.
13. Post Driver Maintenance Schedule
For normal operating conditions. Under strenuous conditions like dusty environments or long work hours, adjust frequency accordingly.

There are parts missing from my order.
If there appears to be any part missing from your package, contact our Customer Support team via the details on the Contact Us page within 7 days of receipt.
I am having difficulties starting the engine in its cooling state.
Check the choke control position and the engine start/stop switch are in the correct position. There might also be moisture on the spark plug—if this is the case, you will need to dry the igniter plug. If the spark plug is producing an electrical spark, you will need to replace the igniter plug. It also might be that too much fuel has been absorbed, and you will have to lessen the fuel supply.
I am having difficulties restarting the machine after a sudden stop.
The fuel may have run out or the carburetor is blocked. If this is the case, you will need to refill the fuel tank or clean the carburetor. The fuel filter may be blocked and will therefore need to be cleaned. However, it could be due to there being too much carbon deposit in the igniter plug—if this is the case, you will have to remove the carbon deposit.
My hammer mechanism is stuck in the casing.
To loosen the hammer mechanism to change it, simply twist the casing out of the fixing. If the casing becomes stuck, insert the metal bar into the holes on the casing and give it a tap. This should detach the casing from the main body without causing any damage.
For all other issues, please contact our Customer Support Team.
