OPERATION GUIDELINES
RECOMMENDED USE OF HYDRAULIC TAMP
After the pole is inserted and plumbed, recommend one crew member shovels dirt in around the pole and
another begins tamping from the bottom of the hole. For even compaction, make sure the dirt is tamped as
the hole is filled. This ensures having a uniformly tamped pole, leaving a minimum amount of excess
material.
If the tamp is leaned in the direction of travel, it will tend to “walk” itself around the pole.
GRADUALLY FILL THE HOLE WHILE TAMPING
WALKING THE TAMP AROUND THE HOLE
ELECTROCUTION HAZARD: When the boom is supporting the pole in or near
energized lines, the tamp operator must wear suitable insulating gloves, sleeves,
and hard hat. Tool hoses which are reinforced with wire braid will become
energized if the vehicle becomes electrically charged. Serious injury or death will
result from contact with this equipment or vehicle should it become electrically
charged. Always use a section of non conductive hose on the tool.
