Operation
(cont’d)
1. Start the hydraulic power source.
Note: Allow the hydraulic power source to run for a
few minutes to warm the hydraulic fluid.
2. Support or secure the post so that it will not fall
when it is extracted.
3. Position the sign post puller next to the post that is
to be pulled. Level the area for a vertical pull.
4. Use either the jaws or chain as follows:
• Serrated jaws: Position the jaws so that they
firmly grip the post flange.
• Chain: Wrap the chain twice around the post.
Leaving some slack in the chain, slide one link
into each of the slots in the guide.
