OPERATION GUIDELINES
3. Drop the eye of pulling chain on the slotted head of the pole puller ram, loop the chain snugly around the
pole, and insert the chain end in the slot on the pole puller ram. Make sure the chain is not kinked or
twisted.
CHAIN ATTACHMENT TO POLE PULLER
4. Attach auxiliary hose from vehicle to the correct coupler on the pole puller. Pull on each hose to make
sure they are fully engaged with the coupler to prevent damage to the pole puller.
5. Wrap a sling around the pole above the center of gravity of the pole and attach the winch line hook to the
sling and snug up the winch line. Activate the pole puller by slowly operating the control valve.
6. After each pull is made, take up on the load line and reposition the boom as necessary, to maintain
control of the pole.
7. Reposition the chain around the pole as required to account for the tapering in the pole.
8. To prevent damage to the pole puller cylinder rod when retracting, maintain the pole puller in an upright
position.
9. Use the Digger Derrick to keep the pole vertical until the pole is freely suspended and the pole puller is
removed.
10. In extreme cases of pole removal, holes may be dug directly alongside the pole to loosen the soil,
assisting the pole puller.
11. DO NOT use the boom to loosen the pole.
LOOSENING DIRT AROUND OLD POLE
Do not hook chain and pole puller together using the chain as a choker chain
around the pole. Both ends of the chain must be attached to the pole puller ram.
STAND CLEAR! Pole puller is capable of developing 40,000 to 60,000 pounds of
force (178,000 to 267,000 N.) Damage or serious injury may occur.
