WARNING
Operating, maintaining, and servicing a Stellar
product may expose you to chemicals including, but
not limited to, engine exhaust, carbon monoxide,
phthalates, and lead. These chemicals are known
to the State of California to cause cancer and birth
defects (or other reproductive harm). To keep your
exposure to a minimum, be sure to avoid breathing
exhaust and service your Stellar product in a well-
ventilated area while wearing gloves or washing
your hands frequently. For more information, go to
www.P65Warnings.ca.gov/passenger-vehicle. www.p65/warning.ca.gov
P65 Warning & Cold Weather Notice
NOTICE
Cold Weather Performance
Although clear data on cold weather performance from every steel
manufacturer is not available for all types and thicknesses of steel, Stellar
Industries is confident that the weldments on our products will operate to
100% of their intended purpose to temperatures down to -40° F / C.
It is recommended it Stellar manufactured equipment needs to be used in
temperatures below -40° F / C, the operator should pull the unit into a
climate-controlled area and allow the weldments to warm up to and then
maintain a temperature above this level.

General Installation
This chapter is designed to serve as a general guide for the installation of a Stellar®hooklift. 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.
PTO and Pump installation instructions are provided by the corresponding manufacturers. For more information
on which PTO and Pump t your application, please contact your local Stellar Distributor or Stellar Customer
Service.
Do not install this hooklift on a chassis not capable of handling the loads imposed on it.
Failure to do so may result in serious injury or death.
Do not weld or drill holes into the side wall of the base tubes.
Hooklift Mounting and Assembly
Study names and locations of the parts and familiarize yourself with the hooklift before starting the assembly.
Reading the step-by-step instructions that follow will be helpful.
Assembly
Select an area for assembly that will be large enough to accommodate the completed unit. The surface of the
work area should be as level as possible. Use the proper hand tools to ensure proper bolt tightness. Refer to
the torque data chart in this chapter for the recommended torque values for di󰀨erent sizes of bolts.
Model Number
Know the model number of the Stellar®Hooklift being mounted. Use this model number whenever referring to
the assembly or parts listing pages. The number is stamped on the name plate which is located on the front
frame member.
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 e󰀨ect 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®Hooklifts 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 Tra󰀩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.

WARNING
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 a󰀨ect 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 di󰀨erent 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.
• Sheer 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 on page 8, applied to the nut, not to the bolt head. Tighten toothed or serrated-type lock
nuts to the full torque value.
NOTICE
*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.
Torquing Information & Warnings
Torque Data Chart

Page 8 | Stellar®NXT18 Installation 127722
• Visually inspect the truck and look for any potential issues. For example: Clearance problems, cross members
extending too high, insu󰀩cient room in front of the hooklift for tarpers, exhaust manifolds, etc., or insu󰀩cient
room in the rear to allow for bumper selection.
NOTICE
Stellar Industries recommends allowing 12” behind the start of clear truck frame for
installation of a tarping system.
• Be sure to square the hooklift on the truck frame to allow for proper measurement. The front of the hooklift
needs to be at least 2.50” behind the cab or any equipment mounted behind the cab.
NOTICE
On some hooklift models, the jib may extend beyond the front of the base.
Step 1: Set The Hooklift Onto The Truck Frame
NOTICE
Every hooklift installation is unique. However, certain guidelines exist that apply to
every model. Listed below is a general set of chronological steps that may be followed
when installing a Stellar Hooklift. If any questions arise during the installation process, feel free to contact your
local dealer or Stellar Customer Service at 800-321-3741.
