Un-Packing
Carefully inspect the body of the post driver for burrs and/or sharp edges. This unit is prepared with a durable high gloss finish to prevent rust but sometimes this process produces burrs. We hand inspect every unit prior to shipping and remove any problems that we come across, but it is the owner’s responsibility to do a thorough inspection before field operation.
Unpack the unit and make sure you have all the following:
Assembly
Do not connect the unit to an air source until the assembly process is completed.
Begin by placing the post driver body on an appropriate work surface with adequate lighting. We recommend having someone available for assistance.
Insert the Safety Cover as shown. Sometimes it will be easier to insert from one side or the other.
Place the air cylinder into position making sure the fittings are facing towards the push button valve of the post driver
With a lock washer on each screw, hand-thread all four of into the air cylinder.
Using the supplied Hex Wrench tighten all four screws. These screws can work lose over time, so they must be periodically checked. A thread-locking adhesive can be used on these as well.
Recheck screw tightness before each use
Finished product should look like this. Connect the two air tubes and the assembly is complete.
Finally connect the two airlines, and thread in the exhaust muffler and your assembly is complete.
Operation
A video detailing the operation of the unit is available on our website at: www.4x4PostDriver.com
Safety
The pneumatic cylinder that comes with this device is very powerful and capable of serious injury. Operating at 90 psi, the cylinder can produce over 175 pounds of force. Do not allow any objects to cross the operating path of the cylinder. Always disconnect the air source before servicing.
Always wear safety glasses and hearing protection while operating this unit.
Keep bystanders, children, and visitors away while operating the post driver. Distractions are liable to result in injury.
Never connect to an air source that can exceed 130 psi. Over pressurizing the post driver may cause bursting, abnormal operation, breakage of the tool, or serious injury.
Never use oxygen, carbon dioxide, or any bottled gas as an air source for this tool. Such gases are capable of explosion and serious injury.
System Description
Posts
It is important to cut a wedge onto the end of the 4×4 pressure treated posts so that they will drive easier into the ground. This can be accomplished with a chainsaw, a radial arm saw, or a circular saw. Also, it is a good idea to measure your posts before you start driving. Most 4x4s will measure 3.5” x 3.5” but every now and then you will come across an oversized post. This could prove difficult to drive due to a tight fit inside the PAD04 post driver.
Getting Started
After the unit is fully assembled, you can connect to an air source and test the operation. When you press the green button, you should hear the air cylinder extend. When the button is released, you should hear the air cylinder quickly and quietly retract.
This opening is what goes over the 4×4 post and is also where the air cylinder travels. Never reach into this opening for any reason. The pneumatic cylinder is very powerful and capable of serious injury.
To avoid serious injury, keep hands and arms clear of this opening.
Field Use
Operating the unit in the field couldn’t be easier. Once the post driver is placed over the post, simply push the green button and the unit will automatically raise. Release the button and the unit will fall and strike the post. After a couple of strikes, most users quickly get the timing down and can operate it like a pro.
That’s it. You are now ready to get in the water and start building your dock!
