1. Determine that the mounting location for the 4420 crane is at least 18” x 15” (45.7 x 38.1
cm).
2. Use the detail on the pr
evious page to drill .938” diameter holes into the mounting
plate. Run tap on the threads of the base to be sure they are clean.
3. Use a crane or lifting device capable of lifting the weight of the Stellar crane. The Stellar
4420 weighs approximately 1050 lbs (475 kg). Note: cranes are shipped with rotation
positioned at 180 degrees from normal stowed travel position. This will allow for easy
installation of the crane and per
manent connection of all hydraulic and electrical
components prior to repositioning into the crane saddle.
4. Connect straps or chain from the lifting device to the lifting rings on the Stellar 4420.
5. Use four (4)

6. Install a washer on each bolt.
7. Apply Loctite Thread locker #277 to the bolts.
8. Using the lifting device, lower the Stellar 4420 just above the crane compartment and
start the bolts. Have someone assist in leveling the crane. Note: the rotation motor
should be to the door side of crane compartment and the boom should be extended
back over the rear bumper.
9. Secur
e the crane using the mounting hardware provided. Note: longer or shorter cap
screws may be required – recommended thread engagement into crane base is 1.00” –
use grade 8, zinc plated cap screws only.
10. Torque the cap screws to 454 ft-lbs.
11. Remove supporting crane.
