Safety Warnings
1. Always follow proper operation and maintenance instructions.
2. Always use approved Personal Protective Equipment (PPE). Operators and all other persons in the
immediate working area must wear protective equipment as well. Noise emitted from the machine
while working can reach above 100 decibels, which can also harmothers in close proximity. We
recommend the following personal protective equipment:
a. Class 4 (SLC80 = 22.4 dB) hearing protection or greater
b. Impact-resistant eye protection with side guards
c. Protective gloves
d. Protective boots
3. Always check fastening screws before use. If they are loose, tighten them.
4. Always check the spark plug before use. Ifitisexposed, itmust be covered by a high-voltage cap.
Check the flameout line and pipes for damage. Ifdamaged, repair or change them before use.
5. Keep the handle clean and dry.
6. Do not add too much fuel. The fuel level should not exceed the neck of the fuel tank. Ifaccidental
overfilling occurs, pour fuel out until the fuel level is within the proper range within the fuel tank. There
should not be anyfuel on the surface of the machine. ALWAYS wipe your post driver clean after
refueling. Only start the post driver after anyexcess fuel has evaporated completely.
7. After refueling, tighten the fuel lid. Be sure to check for fuel leaks or damage to the fuel tank. If
damage is found, turn off the post driver immediately, and do not operate ituntil the damage is
repaired.
8. Never use this post driver inside a building or unventilated area. The engine exhaust contains
poisonous carbon monoxide gas that can build up to dangerous levels in closed areas. These fumes
can cause unconsciousness or death.
9. Do not use the post driver in adverse weather conditions such as thunderstorms, heavy fog, or strong
wind.
10. While operating the post driver, maintain good balance and operate the machine vertically. The
operator should stand and operate this machine from the front.
11. Do not operate the postdriver with one hand or turn the machine upside down horizontally. ALWAYS

Preparations For Use
Installing Inner Pile Head
If the inner pile head (#49) is not pressed on the shock (#43) at this time, you must slide the inner pile head inside
the piling socket and match the small side with the shock. Tap the inner pile head a few times to make sure it is
connected to the shock. As you start using your machine, the inner pile head will press further on the shock and will
not separate again without the use of tools.
Adding Fuel
1. Always turn the engine off and allow adequate time for itto cool before refueling. Only use unleaded
fuel with 86 octane or higher.
2. Never refuel your driver with the engine hot, running, or in an unventilated area. Fuel vapors are
extremely flammable and can cause severe injury or death if ignited by a spark or excessive heat
from a hot engine.
3. Do not add too much fuel. The fuel level should not exceed the neck of the filler fuel tank. If
accidental overfilling occurs, pour fuel outuntil the fuel level iswithin the proper range within the fuel
tank. There should not be any fuel on the surface of the machine. ALWAYS wipe your post driver
clean after refueling. Only start the postdriver after anyexcess fuel has evaporated completely.
4. After refueling, tighten the fuel tank lid.
5. This postdriver uses pure gasoline as fuel. Do not use gasoline mixed with oil. This will result in poor
starting performance and low function.
Before use, install the correct piling socket sleeve for your application as shown below:
Installing Piling Socket Sleeve
Adding Engine Oil
1. Before the first use, drain any oil that might be inside the crankcase, and refill using the bottle of oil
that is supplied with your driver. We suggest adding 2.7 US ounces and then checking the oil. Place
the oil level gauge back in the oil filler neck, BUT DO NOT SCREW IN WHILE CHECKING THE OIL
LEVEL, OR YOU WILL GET A FALSE READING.
2. To avoid damage to the engine, always check the engine oil before starting the driver. Be sure the
engine oil level isadequate.
3. For every 10 hours of use, itis necessary to check the oil level.
4. To check the oil, place the driver horizontally. Unscrew the oil level gauge, and check the oil level as
shown below. Ifthe oillevel islow, add oil. Ifthe oil isdirty, change the oil.
The recommended environmental temperature range of the machine is 5° to 105° F. We recommend the use
of SAE 10W-30 engine oil, which equals to API classification SJ.
See SAE Engine Oil Consistency Table below.
Checking the Air Filter
1. Remove the air filter cover, and check to see if the air filter is clean. If it is dirty, clean it.
2. After checking the air filter, reinstall the air filter cover.

Service and Maintenance
Air Filter Maintenance
After the driver has been used for some time, dirt and dust particles can block the flow of air, which will
result in reduced power and increased oil consumption. Itis necessary to clean the air filter regularly. The
cleaning cycle is usually every 3 months or every 25 hours of operation. When using the driver in
extremely dusty environments, clean it every 10 hours or even every day.
Cleaning the Air Filter
1. Remove the air filter cover, and take out the air filter.
2. Put the air filter into water. Squeeze the water out of the filter and allow it to air dry.
3. Put it in clean oil and rub gently. Take it out and squeeze it dry.
4. After cleaning, assemble the air filter and the air filter cover.
Fuel Filter Maintenance
If the fuel filter is blocked, the post driver will have reduced speed and weaker impact energy.
1. Open the tank lid.
2. Remove the fuel filter from the fuel tank with a metal hook and clean it.
3. When cleaning the fuel filter, clean the fuel tank at the same time as shown below.
Carburetor Maintenance
The fuel tank and the carburetor generally have residual fuel. Over time, the residual fuel can block up the
fuel line causing the engine not to start. Therefore, when the machine is not used for more than one
week, be sure to completely remove the fuel.
1. To drain fuel, remove the fuel inlet pipe and filter from the tank. Press the carburetor fuel bubble
repeatedly until all fuel has been emptied from the lines and carburetor.
2. Empty out any fuel that has drained into the fuel tank, then place the fuel filter and line back inside
the tank.
Spark Plug Maintenance
If the spark plug has too much carbon deposit, it will result in poor engine performance. It is necessary to
regularly maintain and adjust the spark plug every year or every 100 hours of operation.
1. Remove the spark plug as shown.
2. Remove carbon deposit.
3. Adjust to 0.6 – 0.7 mm.
4. Replace the spark plug.
Replacing Engine Oil
1. Dirty engine oil will result in reduced service life of moving engine parts. Itis necessary to
regularly replace engine oil and keep engine oil atproper levels.
2. Replace engine oil every 6 months or after 50 hours of operation.
3. Drain the oil when the engine is hot to guarantee that engine oil can be emptied quickly and
completely.
4. Replacing engine oil:
a. Ensure that the cap of the fuel tank isscrewed tight.
b. Place a proper container near the engine for storing waste engine oil.
c. Remove the engine oil gauge, lean the engine toward the engine oil filler, and discharge
engine oil tothe container as shown below.
d. Place the driver horizontally and add the recommended oil to the bottom edge of the oil
filler. Refer to pages6 and 13 for adding the correct amount of engine oil.
The recommended environmental temperature range of the machine is 5° to 105° F. We recommend the use
of SAE 10W-30 engine oil, which equals to API classification SJ.
