OPERATION GUIDELINES
Once the pole hole is dug to the required depth, it is ready to accept the pole. Make sure soil is packed tight
at bottom of hole, using a tamper (see Recommended Tamp section).
Before hooking the pole, two things must be determined:
• Weight of the pole.
• Proper boom angle required to support the weight of the pole (using the load capacity chart).
• Always use a sling around the pole, do not use the load line as a sling.
Place a sling or butt chain (not the winch line) on the pole above the balance point. The longer the pole, the
closer the sling or butt chain must be to the balance point. If the pole is properly hooked before raising the
pole, there should be little need to align the gains or cross arms once the pole is positioned.
HANDLING POLE
Before raising the pole, verify the boom is at the proper angle and properly hooked to support the weight of
the pole; also make sure the winch line is perpendicular and vertical with the pole. This limits the amount the
pole can move when it is being raised off the ground. Raise the pole slowly.
Serious injury or death will result if control handles become electrically charged
from boom contact with energized conductors and the operator is standing on or
is in contact with the ground. Operate controls from operators platform or while on
vehicle only.
Always use a sling rated for the weight. Use of the load line as a sling will damage
the load line.
Inspect load line and all rigging before lifting load.
