T
The following safety information is vitally
important for safe operation of the TB126J.
Failure to follow these instructions can result in
personal injury or DEATH.
Pre-start Inspection
Prior to each shift, the TB126J shall be given a
visual inspection and function test. See the
“DAILY INSPECTION & MAINTENANCE”
chapter in this manual for a list of items to
inspect and test.
Do not operate the TB126J unless you are
trained and authorized, understand the operation
characteristics of the TB126J, and have
inspected and tested all functions to be sure they
are in proper working order. See the “DAILY
INSPECTION & MAINTENANCE” chapter.
Work Place Inspection and Practices
Do not use the TB126J as a ground for welding.
Ground to the work piece.
Before the TB126J is used, and during use,
check the area in which the TB126J is to be used
for possible hazards such as, but not limited to:
drop-offs or holes
•
bumps and floor obstructions
•
debris
•
overhead obstructions and high voltage
•
conductors
•
hazardous locations
•
inadequate surface and support to withstand
•
all load forces imposed by the aerial platform
•
in all operating configurations
•
wind and weather conditions
•
presence of unauthorized persons
•
other possible unsafe conditions
•
Before using the aerial platform in any hazardous
(classified) location, make certain it is approved
and of the type required by ANSI/NFPA 505 for
use in that particular location.
A recommended safety practice is to have
personnel that are trained in the operation of the
emergency controls working in the immediate
area of the TB126J to assist the platform
operator in the event of an emergency.
When moving the platform, check the clearance
around the TB126J to avoid contact with
structures or other hazards. Always look in the
direction of motion.
Keep ground personnel from under the platform
when the platform is raised.
Secure all accessories, containers, tools, and
other materials in the platform to prevent them
from accidentally falling or being kicked off the
platform.
Do not engage in any form of “horseplay” or
“stunt driving” while operating the TB126J.
Do not permit riders on the machine anyplace
other than on the platform.
Remove all loose objects stored in or on the
machine, particularly in the platform. Remove all
objects which do not belong in or on the
machine.
When other moving equipment is in the area,
take special precautions to comply with local
regulations regarding warnings.
Never steady the platform by positioning it
against another platform.
Do not operate a TB126J that is not functioning
properly, or has been damaged, until the
machine has been repaired by a qualified
maintenance person.
Do not operate a TB126J that does not have all
its decals and placards attached and legible.
Drive the machine with care and at speeds
compatible with conditions. Use extra caution
when driving over rough ground, on slopes, and
when turning.
Know and understand the job site traffic-flow
patterns and obey the flagmen, road signs, and
signals.
P/N 0191915
Watch for bystanders and never allow anyone to
be under, or to reach through, the machine and
its equipment while operating.
Use the recommended transport device when
loading the machine.

1. SAFETY
Electrocution
The TB126J is an all-metal boom, NONINSULATED, aerial work-platform. Do not
operate it near ELECTRICAL conductors.
Regard all conductors as being energized.
Do not operate outside during a thunderstorm.
Tipover & Falling Hazards
Do not operate a TB126J from a position on
trucks, trailers, railway cars, floating vessels,
scaffolds, or similar equipment unless the
application is approved in writing by Snorkel.
If the platform or elevating assembly becomes
caught, snagged, or otherwise prevented from
normal motion by an adjacent structure or other
obstacles such that control reversal does not free
the platform, remove all personnel from the
platform before attempts are made to free the
platform using ground controls.
It is best not to transfer from the platform to
another structure or from the structure to the
platform, unless that is the safest way to do the
job. Judge each situation separately taking the
work environment into account. If it is necessary
to transfer from the platform to another structure
the following guidelines apply:
Where possible, place the work platform
•
over a roof or walking structure to do the
transfer.
Transfer your anchorage from one
•
structure to another before you step
across.
Remember that you might be transferring
•
to a structure where
is required.
Use the platform entrance, do not climb
•
over the guard rails.
All platform occupants MUST wear a fall restraint
device connected to a lanyard anchor point.
Do not exceed the unrestricted platform capacity
shown on the platform.
Do not raise the boom if the TB126J is on soft
ground. Operate the boom only on a firm surface
capable of withstanding all load forces imposed
by the aerial platform in all operating conditions.
personal fall arrest
Care shall be taken to prevent rope, electric
cords, and hoses, etc., from becoming entangled
in the aerial platform.
Raise the platform only when the TB126J is on
level ground.
Maintain a firm footing on the platform floor.
Climbing on the guard rails is prohibited.
Do not use ladders, planks, or other devices to
extend or increase your work position from the
platform.
Do not jerk the controls. Move the controls slowly
and deliberately to avoid jerky and erratic
operation. Always stop the controls in the neutral,
off, position before going in the opposite
direction.
Do not use the boom for any purpose other than
to position personnel, their tools, and materials.
Do not use the TB126J as a crane, hoist, or jack.
Do not operate the TB126J in winds, or wind
gusts, of 28 mph (45 km/hr) or more.
Do not add anything to the TB126J that will
increase the wind loading (billboards, banners,
flags, etc).
Crushing
Always look in the direction of travel. Avoid
overhead obstructions.
Never cover the floor grating or otherwise
obstruct your view below.
Make sure the area below the platform is free of
personnel before lowering.
T
GENERAL SAFETY PRECAUTIONS
Personnel Precautions
If you encounter any suspected malfunction of
the aerial platform, or any hazard or potentially
unsafe condition relating to capacity, intended
use, or safe operation, cease operation and seek
assistance from management.
Operator General Precautions
Make sure that all protective guards, cowlings,
and doors are in place and secure.
Do not carry loads from any point outside of the
platform.

Mounting & Dismounting Precautions
Fuel Handling Precautions
1. SAFETY
Use three points of support when getting on or
off the platform (two hands and one foot or a
similar set of points). Keep the platform clean.
Do not jump off the machine.
Do not dismount while the machine is in motion.
Starting and Stopping Precautions
Do not start until all personnel are clearly away
from the machine.
Before leaving the operator’s station, place the
machine in the stowed position.
When leaving the machine parked or
unattended, remove the starter key from the
MASTER KEY SWITCH
switch to OFF, then lock the
Operating Precautions
Do not modify the TB126J in any way.
When parts or components are replaced, they
shall be identical or equivalent to original Snorkel
parts or components.
Do not override any of the safety features of the
TB126J.
Limit travel speeds according to conditions. Take
into account: grade, surface, congestion,
visibility, side slope, location of personnel, and
other hazards.
Operator Maintenance Precautions
Do not use your hand to search for hydraulic oil
leaks. High pressure hydraulic oil can easily cut
and penetrate your skin — a very serious injury
that requires immediate attention by a medical
specialist trained in that type of injury. Use a
piece of cardboard or wood to search for
hydraulic oil leaks.
Do not attempt repairs unless you are trained.
Refer to manuals and experienced repair
personnel for help.

switch.
Do not smoke or permit open flames while
fueling or near fueling operations.
Never remove the fuel cap or refuel a gasoline
engine while the engine is running or hot. Never
allow fuel to spill on hot machine components.
Maintain control of the fuel filler nozzle when
filling the tank.
Do not fill the fuel tank to capacity. Allow room
for expansion.
Clean up spilled fuel immediately.
Tighten the fuel tank cap securely. If the fuel cap
is lost, replace it with an approved cap from
Snorkel. Use of a non-approved cap without
proper venting may result in pressurization of the
tank.
Never use fuel for cleaning purposes.
For diesel engines, use the correct fuel grade for
the operating season.
T
SAFETY DECALS & PLACARDS
There are several safety decals and placards on
the TB126J. Their locations and descriptions are
shown in this section. Take time to study them.
Be sure that all the safety decals and placards
on the TB126J are legible. Clean or replace them
if you cannot read the words or see the pictures.
Clean with soap & water and a soft cloth. Do not
use solvents.
You must replace a decal or placard if it is
damaged, missing, or cannot be read. If it is on a
part that is replaced, make sure a new decal or
placard is installed on the replaced part. See
your Snorkel dealer for new decals and placards.
Refer to PLACARDS AND DECALS
INSPECTION CHARTs and DRAWINGs in the
“DAILY INSPECTION AND MAINTENANCE”
chapter for part numbers, location, and required
quantities of all placards and decals.
Charge batteries in a well-ventilated area free of
flame, sparks, or other hazards that might cause
fire or explosion.
Use extreme caution when removing radiator
caps. Park the machine and let it cool down
before opening a pressurized compartment.

push it back in. If it pops out again, there is a
problem in its electrical circuit and the TB126J
should be removed from service immediately and
remain out of service until it is repaired by a

Read and understand all the previous chapters in
this manual before you begin to operate a
TB126J.
Dual-fuel is the only optional equipment
discussed in this chapter. For operation of other
optional equipment, see the "OPTIONS" chapter.
CONTROL STATIONS
T
A TB126J can be operated from the groundcontrol box or from the platform-control box.
There are basically two differences between
ground-control and platform-control operations,
both are safety related:
DANGER
Do not attempt to operate the TB126J ground
controls when the platform, booms, or any
other conducting part of a TB126J is in
contact with energized electrical wires or if
there is an immediate danger of such contact.

STARTING FROM THE GROUND-
T
CONTROL BOX
Before you begin to operate the TB126J a
qualified operator must perform the "DAILY
INSPECTION & MAINTENANCE" described in

Pre-start Conditions
After the DAILY INSPECTION & MAINTENANCE
has been performed, put the TB126J into its prestart conditions. Pre-start conditions for starting

1. The ground-control box can override the
platform-control box at any time. If a person
operating the machine from the platform
becomes incapacitated, a person on the
ground can always take over machine control.
2. The TB126J can only be driven from the
platform-control box. The wheels cannot be
made to move from the ground-control box.
This prevents ground-control operators from
running over themselves.

CONTROL BOX
Before you begin to operate the TB126J, a
qualified operator must perform the "DAILY
INSPECTION & MAINTENANCE" described in
the chapter by that name in this manual.
If you want to drive the TB126J with the main
boom down and retracted, you do not need to
extend the rear axles. Therefore, you should go
on to "Pre-Start Conditions" immediately below. If
you want to start the TB126J from the platformcontrol box then extend or raise the main boom,
you first need to extend and lock the rear axles
for stability. Therefore, you should go to the
"EXTEND & LOCK REAR AXLES" section in this
chapter.
Pre-start Conditions
After the DAILY INSPECTION & MAINTENANCE

MOVING THE PLATFORM
T
The engine should already be running (as
described earlier in this chapter) before you start
this section.
Before you can raise or extend the main boom
the rear axles must be extended (see "EXTEND
& LOCK REAR AXLES" in this chapter).
7. OPERATION
DANGER
Death or serious injury can result if a TB126J
tips over. A PRO- 100 might tip over if the
rear axles are retracted while the booms are
up or extended. The TB126J should have its
booms completely retracted and completely
down before retracting the rear axles.
DANGER
Be certain that the space into which you are
about to move the platform, boom, turntable,
and chassis is free of obstructions. Always
look in the direction of movement.
Do not operate near energized electrical
conductors. See the inside-front cover of this
manual for the minimum safe approach
distance to energized power lines.
DANGER
If you operate from the platform-control box,
be sure that the lanyard of your fall restraint
or harness is attached to the anchorage point
on the platform mount. Also, be sure the
gravity gate is closed behind you.
Each of the ways the platform can move is
shown in the following two-page spread. The
photos show the switches to push to move the
platform. The switch call-out numbers (on the
left-hand page) correspond to the illustration
numbers on the right-hand page.
NOTE: The correct procedure for retracting
the rear axles is shown at the end of this
chapter under "RETRACT & LOCK REAR
AXLES."
NOTE: At the end of each work day the
TB126J should be returned to the STOWED
POSITION as described under STOWING in
the "STOWING & TRANSPORTING" chapter.

The hydraulic oil temperature (1) should be
less than 200°F (93°C).
The hydraulic oil level should be between the
two marks on the sight-glass gauge (2).
If necessary, add hydraulic oil at the filler cap (3).
See the “SPECIFICATIONS” chapter for type
and grade of hydraulic oil.
DANGER
Batteries emit hydrogen and oxygen,
elements that can combine explosively. Do
not smoke or permit open flames or sparks
when checking batteries.
Remove the caps (1) from each battery and
visually check to see that the battery fluid is 1/4“
(6 mm) below the bottom of the filler neck (2)
inside each hole.
10. Hydraulic oil leaks
DANGER
Leaking hydraulic oil can cause burns, fires,
falls (slipping), cuts, and puncture wounds (if
under high pressure). Have a qualified trained
maintenance person repair all hydraulic fluid
leaks before you operate a TB126J.
Hydraulic oil leaks are easily visible and can
show up anyplace. Visually inspect the entire
machine for hydraulic oil. Check the ground
under the machine for leaked oil.

Look at the platform end of each boom. Oil can
run down the inside of a boom and drip out the
end.
P/N 0191915
Page 61
11. Tires
TB126J tires are foam filled. Punctures of the
type caused by bolts, screws, or nails are not a
problem. Look for large holes or long cuts
completely through the tire body: holes or cuts
where foam is being forced or eroded out of the
tire. Also, look for large imbedded objects, such
as angle iron, that can rip a tire body open under
some conditions.
10. DAILY INSPECTION & MAINTENANCE
Pay particular attention to all of the wheel nuts.
None should be visibly loose, missing, or
deformed.
12. Bolts & fasteners
Visually inspect all fasteners to see that none is
missing or obviously loose.
Pay particular attention to all of the safety-wired
bolts. Neither the wire nor the bolt heads should
be damaged in any way. (Check the turntable
end of the boom and the end of the lift cylinder
for other safety-wired bolts. Check both sides of
the machine.)
Pay particular attention to all of the upper
rotation-bearing bolts. None should be visibly
loose, missing, or have broken heads.
Pay particular attention to all of the lower (view
from under the machine) rotation-bearing bolts.
None should be visibly loose, missing, or have
broken heads.

TOW KIT
T
DANGER
Improper towing can cause a TB126J to break
away from the towing vehicle. A “runaway”
TB126J can cause death or serious injury.
Do not tow a TB126J faster than 10 mph (16
km/hr). A TB126J can behave erratically
above 10 mph (16 km/ hr).
Check with the tow vehicle manufacture or
manufacturer's literature to be sure the
towing vehicle can safely tow and stop a
41,800 pound (19,000 kg) TB126J on the
steepest grade and type of surface you will
encounter. Remember, the TB126J does not
have brakes when it is towed.
When you tow the TB126J around a corner or
a curve do not turn so sharply that either of
the tow bar chains is pulled tight. If a chain is
pulled tight the steering mechanism might be
damaged or the tow vehicle and TB126J
might jackknife.
12. OPTIONS

DANGER
A “runaway” TB126J can cause death or
serious injury. Disconnecting the disconnectplates will allow the TB126J drive wheels to
turn freely. Before proceeding, be certain the
tow bar is installed and connected to a
towing vehicle that can safely control both
itself and the 41,800 pound (19,000 kg)
TB126J. Be certain the tow vehicle brakes are
set.
1. Remove the tow bar and tie rod weldment
from the storage cradles and lay them near the
front of the chassis.
2. Rotate the turntable until the counterweight is
to the side of the chassis.
DANGER
Death or serious injury can result from being
crushed between the counterweight and tow
vehicle. Do not attempt to attach the tow bar
to the tow vehicle unless the counterweight
is to the side.
3. Attach the tow bar to the towing lug with the
tow pin and snap pin.
4. Attach the tie rod weldment to the tow bar and
the right hand steering yoke.
5. Attach the two tow bar chains to the tie down
lugs.
6. Attach the ring-end of the tow bar to the tow
vehicle.

9. Remove the two bolts (1) that hold each drivewheel disconnect-plate (2).
10. Turn each disconnect-plate (2) over so that
the nipple (3) points inward, then retighten the
bolts (1).
DANGER
At the end of the tow, before you disconnect
the TB126J from the towing vehicle, turn the
disconnect-plates back over so the nipples
are out. This will prevent the TB126J from
rolling when you disconnect it from the tow
vehicle.

GFCI OUTLET
T
The GFCI (ground fault circuit interrupt) is
located under the platform-control box. To use
the outlet set the
switch to GENERATOR.
The GFCI protects against short circuits to
ground. When there is a short to ground the
GFCI shuts off power to the electrical outlets.
MACHINE/GENERATOR
SELF-CLOSING GATE
T
The self-closing gate is designed to automatically
close after you enter or leave the platform. It
helps prevent people from falling off the platform.
SPARK ARRESTOR
T
The spark arrestor prevents incandescent carbon
particles from coming out the tail pipe. Baffles in
the spark arrestor slow the flow of particles
through the exhaust system. The additional time
spent in the exhaust system lets the carbon
completely burn before it comes out the tail pipe.
To reset the outlets:
Unplug the equipment being used.
Press the RESET button on the GFCI.
This should restore power to the outlets. If it
does not, set the
switch to MACHINE and refer the problem to a
trained service technician.
FLASHING LIGHTS
T
The flashing lights alert people that the TB126J
is present. The lights flash at about one flash per
second any time the engine is running. There is
no ON/OFF switch for the flashing lights.

LIMITED WARRANTY
Snorkel warrants each new machine manufactured and sold by it to be free from defects in material and
workmanship for a period of one (1) year from date of delivery to a Customer or for one year after the machine
has been placed in first service in a Dealer rental fleet, whichever comes first. Any part or parts which, upon
examination by the Snorkel Service Department, are found to be defective, will be replaced or repaired, at the
sole discretion of Snorkel, through its local Authorized Dealer at no charge.
Snorkel further warrants the structural components; specifically, the mainframe chassis, turntable, booms and
scissor arms, of each new machine manufactured by it to be free from defects in material and workmanship
for an additional period of four (4) years. Any such part or parts which, upon examination by the Snorkel
Service Department, are found to be defective will be replaced or repaired by Snorkel through its local
Authorized Dealer at no charge; however, any labor charges incurred as a result of such replacement or repair
will be the responsibility of the Customer or Dealer.
The Snorkel Service Department must be notified within forty-eight (48) hours of any possible warranty
situation during the applicable warranty period. Personnel performing warranty repair or replacement must
obtain specific approval by Snorkel Service Department prior to performing any warranty repair or
replacement.
Customer and Dealer shall not be entitled to the benefits of this warranty and Snorkel shall have no obligations
hereunder unless the "Pre-Delivery and Inspection Report" has been properly completed and returned to the
Snorkel Service Department within ten (10) days after delivery of the Snorkel product to Customer or Dealer's
rental fleet. Snorkel must be notified, in writing, within ten (10) days, of any machine sold to a Customer from
a Dealer's rental fleet during the warranty period.
At the direction of the Snorkel Service Department, any component part(s) of Snorkel products to be replaced
or repaired under this warranty program must be returned freight prepaid to the Snorkel Service Department
for inspection. All warranty replacement parts will be shipped freight prepaid (standard ground) from the
Snorkel Service Department or from Snorkel's Vendor to Dealer or Customer.
REPLACEMENT PARTS WARRANTY
Any replacement or service part made or sold by Snorkel is not subject to the preceding
beyond the normal warranty period of the machine upon which the part was installed.
THIS WARRANTY EXCLUDES AND SNORKEL DOES NOT WARRANT:
1. Engines, motors, tires and batteries which are manufactured by suppliers to Snorkel, who furnish their
own warranty. Snorkel will, however, to the extent permitted, pass through any such warranty protection
to the Customer or Dealer.
2. Any Snorkel product which has been modified or altered outside Snorkel's factory without Snorkel's
written approval, if such modification or alteration, in the sole judgment of Snorkel's Engineering and/or
Service Departments, adversely affects the stability, reliability or service life of the Snorkel product or
any component thereof.
3. Any Snorkel product which has been subject to misuse, improper maintenance or accident. "Misuse"
includes but is not limited to operation beyond the factory-rated load capacity and speeds. "Improper
maintenance" includes but is not limited to failure to follow the recommendations contained in the
Snorkel Operation, Maintenance, Repair Parts Manuals. Snorkel is not responsible for normal
maintenance, service adjustments and replacements, including but not limited to hydraulic fluid, filters and
lubrication.
4. Normal wear of any Snorkel component part(s). Normal wear of component parts may vary with the
type application or type of environment in which the machine may be used; such as, but not limited to
sandblasting applications.
5. Any Snorkel product that has come in direct contact with any chemical or abrasive material.
6. Incidental or consequential expenses, losses, or damages related to any part or equipment failure,
including but not limited to freight cost to transport the machine to a repair facility, downtime of the
machine, lost time for workers, lost orders, lost rental revenue, lost profits or increased cost.
This warranty is expressly in lieu of all other warranties, representations or liabilities of Snorkel, either
expressed or implied, unless otherwise amended in writing by Snorkel's President, Vice
President-Engineering, Vice President-Sales or Vice President-Marketing.
SNORKEL MAKES NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION OF THIS LIMITED
WARRANTY. SNORKEL MAKES NO IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE AND DISCLAIMS ALL LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES, INCLUDING BUT NOT LIMITED TO INJURY TO PERSONS OR PROPERTY.
