1.
Pull up on the adapter release ring. Slide the
appropriate adapter into the front head. Release
the adapter release ring so that the adapter is
secured to the front head.
Note: The constant vibration of this tool will
accelerate wear of the adapter release
mechanism. To extend the service life, use a 1/2"
cap screw and nut to secure the adapter to the
tool.
2.
Start the power source.
Note: Allow the power source to run for a few
minutes to warm the hydraulic fluid.
Option: Install a drive cap, as shown, to protect
the end of the sign post.
3.
Slide the sign post into the driver, as shown.
4.
Lift the post and driver to a vertical position, as
shown.
Notes: Posts longer than 2 m (6') may require a
second person to lift the driver and steady the
post.
When the sign post driver is within reach, grasp
both handles firmly.
5.
To start the tool:
HPD-T: Squeeze the trigger bar toward the
handle. Use a partial squeeze for slow driving, or a

After the post is driven, remove the driver and the
spacer (if used).
Note: If you need to drive the post further into
the ground, shut off the power source,
depressurize the hydraulic system, and remove
the adapter. Start the power source. Place the
sign post driver directly onto the sign post and
drive the post to the required height.
8.
When the tool is not in use, stop the power source
to reduce heat and wear on tool components.
