6. Using the boom, move the post into the desired position
and push it into the surface if suitable ground. Ensure
the excavator blade is lowered to add stability.
7. Start the vibration and push the post into the ground,
ensuring the post is pushed vertically downwards.
8. Once the post is installed to the desired depth, simply
release the jaws and lift the Postmaster away.
General Principles of Operation
You may find it useful to reduce oil flow by reducing engine revs – at low flow the vibration
amplitude will be greater.
 Make sure the crowd ram keeps the rubber buffers level and not twisted.
 Try to imagine the vibrator and post as one unit with the excavator merely guiding and
pushing the post.
 Vary the vibration frequency by changing engine speed or feathering the valve to get the best
effect.
 In general, metal posts need higher frequency vibration than wooden ones.
 Posts can be vibrated sideways or extracted.
 Use of a template will aid in ensuring accurate pitch for post and rail fencing.
