Transport without pallet

• Remove all tensioning belts and bits of fastening wood.
• Remove accessory pack, if applicable, and store safely in the packaging for

later attachment.

• Screw suitable eye bolts into the pole heads.
• Hang sling gear into the eyebolts.
• Carefully lift vacuum circuit-breaker off the pallet just enough that pieces of

square timber can be placed underneath.

Note

When fastening the eyebolts to the pole heads, ensure that the contact surfaces
are not damaged.

Note

Place pieces of square timber onto the pallet in such a way that the insulating
operating rods, contact pressure springs, angle levers and dashpots are not
damaged when setting down.
