Installer Notice

According to Federal Law (49 cfr part 571), each nal-stage manufacturer shall complete

the vehicle in such a manner that it conforms to the standards in effect on the date of

manufacture of the incomplete vehicle, the date of nal completion, or a date between

those two dates. This requirement shall, however, be superseded by any conicting

provisions of a standard that applies by its terms to vehicles manufactured in two or more

stages.

Therefore, the installer of Stellar®Cranes and Bodies is considered one of the manufacturers

of the vehicle. As such a manufacturer, the installer is responsible for compliance with all

applicable federal and state regulations. They are required to certify that the vehicle is in

compliance with the Federal Motor Vehicle Safety Standards and other regulations issued

under the National Trafc and Motor Vehicle Safety Act.

Please reference the Code of Federal Regulations, title 49 - Transportation, Volume 5 (400-

999), for further information, or visit http://www.gpoaccess.gov/nara/index.html for the full

text of Code of Federal Regulations.

Chapter 2 - Installation

General Installation

This chapter is designed to serve as a general guide for the installation of a Stellar 7621

Crane on a Stellar Service Body. Each installation is considered unique so certain portions

of this chapter may or may not apply to your direct application. If a question should arise

during the installation process, please contact Stellar Customer Service at (800) 321 3741.

This crane is designed for use with a Stellar Service Body installed on a vehicle that meets

the minimum chassis requirements of the crane. It is the installer’s responsibility to assure

that the crane is mounted on a platform that will support the maximum crane rating of this

crane.

Do not install this crane on a body not capable of handling the loads

imposed on it. Failure to do so may result in serious injury or death.

When installing welder units to the service bodies, it is highly

recommended that a surge protector is installed on the chassis batteries to protect the

crane radio receiver, wiring and other electronic devices from an unexpected electrical

spike or surge. Failure to do so could result in extensive damage to the service body and

crane electrical circuit.

WARNING

NOTICE

Page 6 | Stellar®7621 Telescopic Crane Owner’s Manual

When using the torque data in the

chart, the following rules should be

observed:

• Bolt manufacturer’s particular

specications should be consulted

when provided.

• Flat washers of equal strength

must be used.

• All torque measurements are

given in foot-pounds. To convert

to inch-pounds, multiply by 12.

• Torque values specied are for

bolts with residual oils or no special

lubricants applied. If special

lubricants of high stress ability,

such as Never-Seez compound

graphite and oil, molybdenum

disulphite, colloidal copper or white lead are applied, multiply the torque values in the

charts by the factor .90. The use of Loctite does not affect the torque values listed above.

• Torque values for socket-head capscrews are the same as for Grade 8 capscrews.

• Do not use these values if a different torque value or tightening procedure is given for

a specic application. Torque values listed are for general use only. Check tightness of

fasteners periodically.

• Shear bolts are designed to fail under predetermined loads. Always replace shear bolts

with identical grade.

• Fasteners should be replaced with the same or higher grade. If higher grade fasteners

are used, these should only be tightened to the strength of the original.

• Tighten plastic insert or crimped steel-type lock nuts to approximately 110 percent of the

dry torque values shown in the chart below, applied to the nut, not to the bolt head.

Tighten toothed or serrated-type lock nuts to the full torque value. Note: “Lubricated”

means coated with a lubricant such as engine oil, or fasteners with phosphate and oil

coatings. “Dry” means plain or zinc plated without lubrication. Tighten lubricated bolts

to approximately 80% of dry bolts.
