This chapter contains information regarding the
operation of Stellar manufactured articulating
cranes. Please study the following pages to ensure
your familiarity with the operation process. This
understanding is vital to the safe and efficient
operation of the crane.
Job-Site Set-Up
Thoroughly plan the lift before positioning the vehicle.
Consider the following:
1. The vehicle should be positioned in an area free
from overhead obstructions to eliminate the need
for repositioning.
2. Position the vehicle so that it is impossible for any
portion of the equipment to come within the
minimum required safe distance of any power line.
Maintain a clearance of at least 10 feet between
any part of the crane, load line, or load, and any
electrical line or apparatus carrying up to 50,000
volts. One foot additional clearance is required for
every additional 30,000 volts or less. Remember to
allow for winds that cause power lines to sway. It is
recommended that a signal person be used when
the vehicle is set-up near power lines.
3. The vehicle should also be positioned on a firm
and level surface that will provide adequate
support for the outrigger loading. Use extreme
caution when setting up near overhanging banks
or excavations.
4. The parking brake must be set on the vehicle and
the drive axle disengaged before performing a
crane operation.
5. The outriggers must be extended to stabilize the
truck before beginning operation.

Gear-Bearing Bolt Maintenance
Anytime a gear-bearing bolt is removed, it
must be replaced with a new bolt of the
identical grade and size. Once a bolt has
been torqued to 75% of its proof load and
then removed, the torque coefficient may
no longer be the same as when the bolt was
new thus giving indeterminate damp loads
after torquing.
Warning!
Failure to replace gear-bearing
bolts may result in bolt failure due
to metal fatigue causing serious
injury or even death.
1. Bolt manufacturer’s particular
specifications should be consulted when
provided.
2. Flat washers of equal strength must be
used.
3. All torque measurements are given in
foot-pounds. To convert to inch-pounds,
multiply by 12.
4. Torque values specified are for bolts with
residual oils or no special lubricants
applied. If special lubricants of high stress

WARNING!
Please read the following section before
performing any work on the
hydraulic/electrical system of your crane.
This section contains vital safety information
and maintenance guidelines for your
crane. If questions should arise, please
contact Stellar Customer Service at 800-
321-3741
Never modify or alter any of the equipment,
whether mechanical, electrical, or hydraulic,
without Stellar Industries’ approval.
Release system pressure before attempting to
make adjustments or repairs.
Do not attempt service or repair when PTO is
engaged.
Disassemble and assemble hydraulic
components on a clean surface.
Do not rely on the hydraulic fluid to support
the boom or crane.
Contaminants in a hydraulic system affect
operation and will result in serious damage to
the system components. Dirty hydraulic
systems are a major cause of component
failures.
If evidence of foreign particles is found in the
hydraulic system, flush the system.
When installing metal hydraulic tubes, tighten
all bolts finger tight. Then , in order, tighten the
bolts at the rigid end, the adjustable end, and
the mounting brackets. After tubes are
mounted, install the hoses. Connect both
ends of the hose with all bolts finger tight.
Position the hose so it does not rub the
machine or another hose and has a minimum
of bending and twisting. Tighten bolts in both
couplings.
Clean all metal parts in a nonflammable
cleaning fluid. Then lubricate all components
to aid in assembly.
Hydraulic fluid expands when heated. This
raises the pressure in an unventilated tank.
Release the tank pressure before removing the
cap completely. Failure to do so may cause
the oil to shoot out of the tank very rapidly and
cause severe burns.
Warning! If hydraulic fluid escapes, the boom
or crane can fall immediately. Make sur
ound or blocking is supporting the boom
gr
before performing any maintenance or repair.
e the
Due to manufacturing methods, there is a
natural curvature to a hydraulic hose. The
hose should be installed so any bend is with
this curvature.

Chapter 10 - Troubleshooting
41Troubleshooting 41
This chapter will list a number of
potential problems that may occur
while operating the crane. Most
problems are easily solved using the
solutions portion of this chapter. If
problems persist, please contact
Customer Service at Stellar Industries
1-800-321-3741.
Problem: Crane will not operate.
Solutions:
• Make sure that the parking brake is engaged.
• Make sure that the PTO is engaged.
• Make sure that there is 12V power going to
the radio receiver. If there is no power going
to the receiver, trace back to the power
source and check for a blown fuse or loose
ground connection.
• Make sure that the transmitter batteries are
fully charged. (Rechargeable batteries are
good for 11 months or 200 charges)
• Make sure that the hydraulic pump is
operating at its rated flow or GPMs. Check
the flow by using the flow meter to determine
the GPMs. It is possible that the hydraulic
pump is getting weak. If this is suspected,
contact Stellar Customer Service.
Problem: Crane operates slowly.
Solutions:
• Make sure that the crane is receiving the
recommended GPMs to operate.
• Check the level of hydraulic fluid in the
reservoir. Add fluid as needed.
• Check to see if the valve bank flow valve is
operating.
• Make sure the proportional valve is receiving
12V power when operating a function.
Problem: Crane will operate manually but
will not operate electrically.
Solutions:
• Make sure that there is 12V power going to
the radio receiver. If there is no power going
to the receiver, trace back to the power
source and check for a blown fuse or loose
ground connection.
• Make sure that the parking brake is engaged.
• Make sure that the parking brake switch is
working properly. Check the parking brake
switch by performing a continuity test. If the
switch is defective, simply replace it.
• Make sure the “Power” LED is on outside the
receiver door cover. This light is the upper
light on the receiver door. If the light does not
come on, check wiring back to the fuse. If
the fuse is OK, check system ground wires
and connections.
• Make sure the green LED on the receiver
door is lit green. This light will come on when
the red e-stop is pulled upward and the toggle
switch is activated on the transmitter. If the
radio system does not link up and no green
light is lit on the receiver - make sure that the
battery is fully charged, check the battery
contact points to make s ure they are not
tarnished or corroded. Clean contact points
and recharge or replace the battery.
• When battery voltage is acceptable, the
power LED light on the transmitter will be
solid. If the voltage becomes low, the LED
light will begin to blink and the battery will
need to be charged or replaced.
If problems persist, please contact
Stellar Customer Service at:
1-800-321-3741
4215000 Owner’s Manual
Problem: Cylinder drifts outward or
downward.
Solutions:
• Check to see if there is air in the hydraulic
system. Operate all cylinders connected to
the hydraulic system. Start with the extension
cylinder, then operate the main boom, winch,
rotation, and ending with the hydraulic
outriggers, if installed. When operating,
extend each cylinder halfway out, retract all
the way in, and then extend until the cylinder
rod is at the end of its stroke. Operate
cylinders slowly so air is pushed thru the
system to the reservoir. Repeat this cycle 2-3
times.
• Make sure the holding valves are operating
properly. Remove, clean, and then inspect
each holding valve. When removing a
holding valve, always relieve the pressure
inside the cylinder by loosening jam nut of the
holding valve and turning set screw
inward/clockwise. Count the number of turns
until the set screw is seated. When
reinstalling the holding valve, make sure the
valve is reset by turning the set screw the
number of turns it took to relieve the
pressure. Finish by tightening the jam nut.
• Check the cylinder rod for scratches. If a
scratch is located on the cylinder rod,
hydraulic fluid can pass thru and cause a loss
of pressure. Replace cylinder rod or cylinder.
• Check to see if the piston seals are damaged.
If they show signs of damage, install a new
cylinder seal kit.
Problem: Crane will operate manually but
will not operate electronically.
Solutions:
• Make sure the “Power” LED is on outside the
receiver door cover. This light is the upper
light on the receiver door. If the light does not
come on, check wiring back to the fuse. If
the fuse is OK, check system ground wires
and connections.
• Make sure the green LED on the receiver
door is lit green. This light will come on when
the red e-stop is pulled upward and the toggle
switch is activated on the transmitter. If the
radio system does not link up and no green
light is lit on the receiver - make sure that the
battery is fully charged, check the battery
contact points to make s ure they are not
tarnished or corroded. Clean contact points
and recharge or replace the battery.
• When battery voltage is acceptable, the
power LED light on the transmitter will be
solid. If the voltage becomes low, the LED
light will begin to blink and the battery will
need to be charged or replaced.
Problem: Not all crane functions operate
using the radio remote transmitter or crane
operates intermittently.
Solutions:
• Make sure that the function switch is working
properly. If the switch is defective, simply
replace it.
• Make sure that there is power going from the
valve bank twin solenoid or to the function
that will not operate. If no power is going to
the twin solenoid, check wiring connections
on wire harness plug connector for broken
wires, loose connection or poor crimp. If
power is going to the solenoid valve, it may
not be opening to allow hydraulic oil to the
function that is not operating. Check the twin
solenoid for polarity, if solenoid does not
magnetize, replace the twin solenoid.

Limited Warranty Statement
®®
Stellar Industries, Inc. (Stellar) warrants products designed and manufactured by Stellar to be free from defects in material and workmanship
under proper use and maintenance. Products must be installed and operated in accordance with Stellar’s written instructions and capacities. The
warranty period shall cover the following:
Twelve (12) month warranty on parts from the date recorded by Stellar as the in-service date, not to extend beyond twenty-four (24) months from
date of manufacture,
Twelve (12) month repair labor from the date recorded by Stellar as the in-service date, not to extend beyond twenty-four (24) month from date of
manufacture, and
Thirty-six (36) month warranty on all Stellar Crane and Hooklift structural parts from the date recorded by Stellar as the in-service date, not to
extend beyond forty-eight (48) months from date of manufacture.
The in-service date will be derived from the completed warranty registration card. In the event a warranty registration card is not received by
Stellar, the factory ship date will be used.
Stellar’s obligation under this warranty is limited to, and the sole remedy for any such defect shall be, the repair and/or replacement (at Stellar’s
option) of the unaltered part and/or component in question. Stellar after-sales service personnel must be notified by telephone, fax, or letter of
any warranty-applicable damage within fourteen (14) days of its occurrence. If at all possible, Stellar will ship the replacement part within 24hours of notification by the most economical, yet expedient, means possible. Expedited freight delivery will be at the expense of the owner.
Warranty claims must be submitted and shall be processed in accordance with Stellar’s established warranty claim procedure. Stellar after-sales
service personnel must be contacted prior to any warranty claim. A return materials authorization (RMA) account number must be issued to the
claiming party prior to the return of any warranty parts. Parts returned without prior authorization will not be recognized for warranty consideration.
All damaged parts must be returned to Stellar freight prepaid; freight collect returns will be refused. Freight reimbursement of returned parts will
be considered as part of the warranty claim.
Warranty service will be performed by any Stellar new equipment distributor, or by any Stellar-recognized service center authorized to service the
type of product involved, or by the Stellar factory in the event of a direct sale. At the time of requesting warranty service, the owner must present
evidence of date of delivery of the product. The owner shall be obligated to pay for any overtime labor requested of the servicing company by the
owner, any field service call charges, and any towing and/or transportation charges associated with moving the equipment to the designated
repair/service provider.
All obligations of Stellar and its authorized dealers and service providers shall be voided if someone other than an authorized Stellar dealer
provides other than routine maintenance service without prior written approval from Stellar. In the case repair work is performed on a Stellarmanufactured product, original Stellar parts must be used to keep the warranty in force. The warranty may also be voided if the product is
modified or altered in any way not approved, in writing, by Stellar.
The owner/operator is responsible for furnishing proof of the date of original purchase of the Stellar product in question. Warranty registration is
the ultimate responsibility of the owner and may be accomplished by the completion and return of the Stellar product registration card provided
with the product. If the owner is not sure of registration, he is encouraged to contact Stellar at the address below to confirm registration of the
product in question. This warranty covers only defective material and workmanship. It does not cover depreciation or damage caused by normal
wear and tear, accident, mishap, untrained operators, or improper or unintended use. The owner has the obligation of performing routine care
and maintenance duties as stated in Stellar’s written instructions, recommendations, and specifications. Any damage resulting from
owner/operator failure to perform such duties shall void the coverage of this warranty. The owner will pay the cost of labor and supplies
associated with routine maintenance.
The only remedies the owner has in connection with the breach or performance of any warranty on the Stellar product specified are those set
above. In no event will Stellar, the Stellar distributor/dealer, or any company affiliated with Stellar be liable for business interruptions, costs of
delay, or for any special, indirect, incidental, or consequential costs or damages. Such costs may include, but are not limited to, loss of time, loss
of revenue, loss of use, wages, salaries, commissions, lodging, meals, towing, hydraulic fluid, or any other incidental cost.
All products purchased by Stellar from outside vendors shall be covered by the warranty offered by that respective manufacturer only. Stellar
does not participate in, or obligate itself to, any such warranty.
Stellar reserves the right to make changes in design or improvement upon its products without imposing upon itself the same upon its products
theretofore manufactured.
This warranty will apply to all Stellar Hooklifts, Stellar Service Trucks, & Truck-mounted Cranes shipped from Stellar’s factory after July 1, 2005.
The warranty is for the use of the original owner only and is not transferable without prior written permission from Stellar.
