Assembly Instructions:
If the crane is improperly assembled, it might malfunction and result in serious personal injuries.
Read this instruction manual in its entirety before assembling the crane; only assemble the crane if you fully
understand both the associated risks and the manufacturer-approved assembly procedure discussed below.

Failure to apply the assembly procedure described in Steps 1-7 that follow constitutes misuse of the product.

ONLY qualified personnel should assemble the crane.

DO NOT modify the crane in any way unless and until you receive written approval from Vestil.

DO NOT use the crane if you notice damage to or deformation of the beam, uprights, or any component of
either of the leg assemblies. Using the crane despite weakness of a structural component could result in crane
collapse.

DO NOT use the crane if any of the hardware (bolts, nuts, clamps, etc.) is damaged; you could sustain serious
injuries if the crane collapses. Contact Vestil to order replacement parts.

DO NOT use the crane if any of the casters is damaged. A damaged caster may cause the crane to tip over
while hoisting or supporting a load.

Modifying the crane in any way without first receiving written approval of the modification from Vestil
automatically voids the limited warranty.

The crane is designed for both indoor and outdoor use. However, it should be sheltered from the weather
when not in use.

Inspect the crane for damage before each use.
