23315 Owner’s Manual
STABILITY
Know the crane components and their
capabilities and limitations. Overloading the
crane may result in serious injury to self and
others, and damage to the equipment and
immediate surroundings.
Never exceed manufacturer’s load ratings.
These ratings are based on the machine’s
hydraulic, mechanical, and structural design
rather than stability.
The supporting surface under the service truck
must be able to support the weight of the
machine and its load. Use outrigger pads if
necessary.
Park the vehicle on level ground and extend
the outriggers fully out and then down.
Keep feet and legs clear when lowering
outrigger jacks.
Never operate the crane without making sure
the outriggers are positioned on stable, flat
ground.
Set the parking brake and disengage the
drive axle before attempting a lift.
LOAD SAFETY
Operate the crane in compliance with the
load capacity chart at all times. Know the
weight of the load being lifted. Do not rely on
the overload device to determine maximum
rated loads. If the crane is picking more than
the maximum rated load, the overlord
protection device may be malfunctioning.
Discontinue use immediately and contact
Stellar Customer Service for support.
Never use a sling bar or anything larger than
the hook throat that could prevent the hook
latch from closing. This would negate the
safety feature.
Do not apply side loads to the booms.
Do not leave a crane load suspended or
unattended.
Do not walk under suspended loads.
Do not position any load over a person nor
should any person be permitted to place him
or herself under a load.
Do not use the boom or the winch to drag a
load.
Do not use the crane boom to push
downward onto anything.
ELECTROCUTION
Allow extra space for swaying power lines in
windy conditions.
Keep a minimum of ten feet between any
portion of the crane and an electrical line.
Add an additional 12" for every additional
30,000 Volts or less.
Remember - Death or serious injury can occur
when working near power lines or during
electrical storms.
Use a signal person when operating near
electrical sources.
ENVIRONMENT
Do not operate the crane during electrical
storms.
In extreme cold, allow adequate time to
warm the truck before engaging the PTO. Do
not rev the truck engine and over speed the
hydraulic pumps as permanent damage to
the pumps may occur. Follow the vehicle
owner’s manual regarding operating the
vehicle in such adverse conditions.
In dusty work areas, every effort must be taken
to keep dust and sand out of the moving parts
of the machinery.
In high humidity work areas, keep parts as dry
as possible and well lubricated.

Operation 3
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.
This chapter contains information regarding
the operation of Stellar manufactured
telescopic 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.
Crane Controls
1. Be familiar with the sequence and
operation of the crane controls.
2. Each individual crane function should
have control function decals. Replace
them immediately if they are missing or
illegible.
3. Keep hands, feet, and control levers
free from mud, grease, and oil.
4. Be familiar with the remote control and
how it operates before attempting to lift
a load.
5. Be prepared before beginning
operation of the crane:
• All protective guards must be in place.
• Be aware of the surroundings: low
branches, power lines, unstable
ground.
• Be sure all safety devices provided are
in place and in good operating
condition.
• Be prepared for all situations. Keep
fire extinguisher and first aid kit near.
• Be sure all regular maintenance has
been performed.
• Visually inspect all aspects of the
crane for physical damage.
• Check for fluid leaks.
• Make sure the outriggers are down
and stable.
ATTENTION
Stellar Industries, Inc. is not liable
for accidents incurred by the
crane because of the operator’s

illegible,replace immediately. (See Chapter
5: Decals)
3. Lift load slightly off the ground to check the
safety of the cargo. Do not use stability to
determine the safety. Consult the capacity
charts and strictly adhere to them.
4. Be constantly aware of the boom position
when operating the controls.
5. The boom tip should be centered directly
over the load before making the lift to
avoid swinging.
6. Do not drag loads with the crane.
7. Do not attempt to lift fixed loads.
8. Do not load boom in a sideways direction.
9. Know the weight of the rigging and load to
avoid overloading the crane.
10. Do not extend or rotate a load over
anyone.
11. Wear protective gear such as hard hat,
safety glasses, steel-toed boots, and gloves.
12. Maintain a minimum of 5 full wraps of wire
rope on the winch drum at all times.
Hook Precautions
1. Hooks are designed and manufactured to
lift specific loads. The specified rated load of
a hook applies to loads held uniformly in
direct tension and does not take into
account shock loads, hook tip loading, side
loading, bending, torsional, or related loads.
2. Do not attempt to lift a load that is larger
than the load rating of the hook.
3. Never use a hook’s yield point as an
indicator of its capacity.
4. Do not use a hook to lift personnel.
5. Know the rated load of the hook in use.
6. Never weld attachments to a finished hook
in field applications. This will alter and
destroy the design properties of the hook
material.
7. Keep fingers, hands, body, and loose
clothing from between the hook and the
load.
8. Avoid shock loading.
9. Inspect the hook regularly for excessive wear
and maintain it in safe operating condition.

Service
The following general suggestions should
be helpful in analyzing and servicing your
crane. Using the following systematic
approach should be helpful in finding and
fixing problems:
1. Determine the problem.
2. List and record possible causes.
3. Devise checks.
4. Conduct checks in a logical order to
determine the cause.
5. Consider the remaining service life of
components against the cost of parts
and labor necessary to replace them.
6. Make the necessary repair.
7. Recheck to ensure that nothing has
been overlooked.
8. Functionally test the new part in its
system.
Stellar Industries recommends the first
filter change to occur after the first 250
hours of service.* The second, and
every subsequent change, should
occur after every 1,000 hours of
service. By following these guidelines,
the hydraulic oil should last up to
6,500 hours.
*Note: These recommendations are based on normal
working parameters. If operating in less than favorable
conditions (excessive dust, moisture, etc.), be sure to check
the filter gauge often for filter change notice.
Inspection Checklist
For a more detailed outline of scheduled
inspection points, refer to the Stellar
Inspection Checklist at the end of this
chapter. This list is an excellent guide for the
inspection tasks that will help maintain the
quality of your Stellar product. Feel free to
photocopy the checklist as needed.
ATTENTION
Every six (6) months, remove the
hydraulic pump from the PTO and
lubricate the splines using Chelsea
Lubricant #379831 or Stellar PN 20885.
Failure to lubricate shaft splines will cause
damage to the PTO and Hydraulic pump.
Important: Prior to washing the Stellar
crane, the radio remote receiver located
on the crane mast must be covered to
prevent any water from entering the
plastic housing. Avoid any direct water
pressure to the radio remote receiver.

Wire Rope Inspection Points
While inspection of the entire rope is
required, attention should be directed to
these critical points:
1. Pick-up Points for signs of wear due to
stress from repeated lifts.
2. End Attachments for corrosion and broken
wires at both ends of the rope.
3. Drums for signs of corrugation and wear
that may lead to wire damage.
4. Sheaves to ensure that each sheave has
the proper groove size and contour.
5. Abuse Points for heavy amounts of
scuffing and scraping.
It is important to perform detailed
inspections of all ropes associated with the
crane. These inspections can be divided
into two types:
1. Frequent Inspection
A. All running ropes should be inspected
once each working day. These visual
observations will be concerned with
discovering damage that may be an
immediate hazard. The following
concerns should be addressed:
1. Distortion of the rope.
2. General corrosion.
3. Broken or cut strands.
B. Use caution while inspecting sections of
rapid deterioration.
C. Use caution while inspecting boom
hoist ropes. Proper inspection is critical
but difficult.
2. Periodic Inspection
A. Inspection frequency will be
determined by a qualified person and
will be based on such factors as
expected rope life, environment
conditions, capacity of typical lifts,
rates of usage, and exposure to shock
loads. Periodic inspection needs to be
performed at least annually.
B. Periodic inspections will be performed
by a qualified individual and will cover
the entire length of the rope. Only the
surface wires of the rope need to be
inspected. This inspection will be
concerned with discovering damage
that may be an immediate hazard. The
following concerns should be
addressed:
1. Distortion of the rope.
2. General corrosion.
3. Broken or cut strands.
4. Reduction of rope diameter.
5. Corroded or broken wires at end
connections.
6. Corroded, cracked, bent, worn, or
improperly applied end
connections.
C. Use caution when inspecting the
following:
1. Sections in contact with saddles,
equalizer sheaves, or other sheaves
where rope travel is limited.
2. Sections of the rope at or near ends
with corroded or broken wires.
Wire Rope Replacement
Rope replacement guidelines are as follows:
1. Broken wires, including standing ropes
with more than two broken wires in one
lay or more than one broken wire at an
end connection.
2. Wear of one-third the original diameter of
the outside wires.
3. Distortion of the rope structure.
4. Evidence of heat damage.
5. Reductions from nominal diameters of
more than 1/64 in. (0.4 mm) for diameters
from 5/16 in.(19.0 mm) and 1/32 in. (0.8
mm) for diameters from 3/8 in. (9.5 mm) to
and including 1/2 in. (13.0 mm).
Wire Rope Maintenance
Proper maintenance is key in ensuring a
long lasting rope. These three tips will help:
1. Store the rope to prevent damage.
2. Avoid objects that may scrape, bend, or
crush the wires of the rope.
3. Always keep the rope well-lubricated.
Wire Rope Maintenance

Maintenance 11
Holding Valve Inspection Procedure
The cylinders are equipped with holding
valves that prevent sudden movement of
the cylinder rods in the event of a hydraulic
hose or hydraulic component failure. The
valve is checked in the following manner:
1. Identify the cylinder in question.
2. Identify the holding valves and the
cylinder direction in question.
a. Cylinder Extend.
b. Cylinder Retract.
3. Place the machine so that the cylinder
will be located in the appropriate testing
position.
4. Pick the load (Do not exceed capacity,
rated or stability).
5. Disengage hydraulics.
6. Operate crane functions.
A. If the cylinder creeps (lowering the
load), replace the holding valve.
B. If the cylinder does not creep (load
stays suspended), the valve is
operational.
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.
Torque Data Chart
When using the torque data in the charts
above, the following rules should be
observed.
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
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.
5. Torque values for socket-head capscrews
are the same as for Grade 8 capscrews.
