CAUTION
!
WARNING
!
Read and understand all manuals and instructional material listed on cover, inside
front cover and introduction page of this Manual before starting, operating or
performing maintenance procedures on this equipment.
Regardless of previous experience operating similar equipment, the operator
must be given sufficient opportunity to practice with the handler in a safe, open
area (not hazardous to people or property) to gain operating skills and the
proper “feel” for controls and operating clearances required for safe, efficient
operation.
JLG/GRADALL Material Handlers are equipped with a right-side rearview mirror.
This mirror is intended as an operator’s aid and does not replace the requirement
for line-of-sight. Certain job site and machine conditions may require use of a signal
person to help the operator when picking, placing or transporting a load. Never
operate the handler until you know pick-up point, line of travel and landing point
are clear. Always be aware that objects in mirror are closer than they appear.
Safety Precautions
Make sure all DANGER, WARNING, CAUTION and INSTRUCTIONAL DECALS
are in place and can be read. Clean or replace decals as required.
Ensure handler is on a firm, level surface before lifting or placing load. Have
surface leveled if necessary. Unit can tip over if load is raised with handler
on a soft or uneven surface.
Be aware that when rotating the platform within indicated area on capacity
charts, it can swing into tires. Be sure to allow clearance to avoid damage to
tires.
WATCH FOR THESE SYMBOLS ;
THEY CALL YOUR ATTENTION
TO SAFETY NOTICES.
This symbol indicates an
extreme hazard which will result
in high probability of death or
serious injury if proper
precautions are not taken.
This symbol indicates a hazard
which could result in death or
serious injury if proper

When traveling at high rates of speed, use two wheel front steer mode and
slow the machine prior to turning.
Do not change steer mode while the machine is traveling. Change the
steer mode only when machine is stopped.
Always look in the direction of travel. Reduce speed and be especially carefulwhen traveling in reverse and/or turning. Bring the machine to a complete
stop before changing the direction of travel.
Travel in reverse only at slow rates of speed.
When turning, the forks on the four wheel steer machine sweep through an arc
beyond the turn radius of the tires. Maintain adequate clearance between
the forks/load and other objects.
If load or conditions obstruct view, use a signal person when lifting, carrying
or placing a load.
Loose clothing can get caught in moving machinery and can also cause accidental
actuation of controls. Dress properly for the job.
Be alert to any unusual response to controls. If unusual response is noticed,
position handler in a safe area, lower forks to ground, apply parking brake, stop
engine and remove key from ignition switch. Tag steering wheel to forbid
operation and notify maintenance personnel.
Operator must be seated with
seat belt fastened, transmission
control lever in “Neutral”
position, parking brake applied
and all hydraulic controls in
“Neutral” before starting engine.

SAFETY HIGHLIGHTS
Keep hands, gloves, shoes, control knobs and pedals clean. Slippery controls
can cause accidents. Keep a firm grip on the steering wheel when traveling.
Load capacities are based on load center being within .6m (24 inches)
from front vertical face of forks.
Release trapped pressure before disconnecting, opening or removing any
hydraulic component.
Keep all windows and mirror(s) clean. Adjust mirror(s) as
visibility, before and during opera
Do not increase engine speed with the transmission in forward or
reverse and the service brake pedal depressed in an attempt to get quicker
hydraulic performance. This could cause unexpected machine movement.
After bringing the material handler to a stop using the service brake, place
the directional control lever in neutral, and set the park brake prior to lifting
a load.
Allow the handler to slow down, or use the service brakes prior to down-shifting.
Do not downshift more than one gear at a time.
When traveling on downhill slopes, downshift to a lower gear and use the service
brake as necessary to maintain a slow speed. Do not shift into neutral and
coast downhill.

TWO METHODS OF USING THE CAPACITY CHART.
SAMPLE ONLY - USE CHART IN CAB
Method 1
1. The operator must determine:
BOOM EXTENSIONNUMBER where the load
is to be placed.
BOOM ANGLE where the load is to be
placed.
2. On the capacity chart, find the arc for the boom
extension number, and follow it down to the boom
angle.
3. The number in the load zone where these two cross
is the maximum capacity for this lift. If the two cross
at a division between zones, the smaller number
must be used.
Method 2
1. The operator must determine:
HEIGHT where the load is to be placed.
DISTANCE from the front of the machine
where the load is to be placed.
2. On the capacity chart, find the line for the height and
follow it over to the distance.
3. The number in the load zone where the two cross is
the maximum capacity for this lift. If the two cross
at a division between zones, the smaller number
must be used.
For each method, the number in the load zone must be
equal to or greater than the weight of the load to be
lifted. Determine the limits of the load zone on the
capacity chart by boom angle AND boom extension number.
Keep the load within theses limits.
9151-3207 REV.-
TIPOVER HAZARD. Failure to comply with
instructions could result in death or serious
injury.
The operator MUST:
1. Make sure the handler is on a firm, level surface
before lifting or placing a load.
2. Make sure that the capacity charts are for the
appropriate Gradall model.
3. Make sure that the Part Numver shown on the
attachment's Serial Number Plate matches the Part
Number shown on the capacity chart.
4. Be sure of the WEIGHT of the load to be lifted.
For safe operation of machine, and to minimize risk of
serious injury, READ AND OBSERVE the following:
1. Only trained and authorized personnel may operate this
machine.
2. Before operating, read and understand all capacity charts,
operator manual and safety manuals.
3. Operator must be seated with seat belt fastened. Assure all
controls are in neutral before ignition switch is turned on.
4. Do not travel with boom raised. When traveling, fully
retract boom and place forks in carry position, which is
approximately 4 feet (1.2 m) above ground. Tilt carriage
back slightly to cradle load. Use extreme caution when
turning.
5. On inclines, travel with load up-grade.
Located on right cab wall
6. Keep others away from machine when operating. Do not
allow others to stand under boom or load. Always look in
direction of travel.
7. Use extreme care when handling long, high or wide loads.
Do not handle unstable or loosely stacked loads.
8. Forks must be centered under load, and spaced apart as far
as possible.
9. Level machine before lifting any load above 4 feet (1.2m).
10. Improper use of machine could result in machine tipping
over. If machine starts to tip over, do not leave operator's
seat. Lean away from tip, and brace yourself.
11. Keep mirror(s) clean and properly adjusted. Objects in
mirror(s) are closer than they appear.

Battery-Boosted Starting
If you ever have to battery-boost start (jump-start) your handler, proceed as
follows:
• Never allow vehicles to touch
• Connect the positive (+) jumper cable to positive (+) post of discharged
battery
• Connect opposite end of positive (+) jumper cable to positive (+) post of
booster battery
• Connect the negative (-) jumper cable to negative (-) post on booster battery
• Connect opposite end of negative (-) jumper cable to ground point on machine
away from discharged battery
• Follow standard starting procedures
• Remove cables in reverse order after machine has started
ENGINE OPERATION
Normal Engine Operation
Observe gauges frequently to be sure all engine systems are functioning
properly.
The voltmeter shows the “charge/discharge” state of the battery charging system.
With the engine running, meter should indicate 13.5 to 14 volts. With engine
stopped, meter indicates battery charge (12 volts).
Be alert for unusual noises or vibration. When an unusual condition is noticed,
park machine in safe position and perform standard shut-down procedure. (See
Page 1.1) Report condition to your supervisor or maintenance personnel.
Avoid prolonged idling. Idling causes engine temperature to drop and this
permits formation of heavy carbon deposits and dilution of lubricating oil by
incompletely-burned fuel. If the engine is not being used, turn it off.
Stopping the Engine
• To stop engine, perform standard shut-down procedure shown on
page 1.1.
• Operate engine at low idle for 3 to 5 minutes before turning it off. This
allows engine coolant and lubricating oil to carry excessive heat away from
critical engine areas, including turbocharger.
• Do not “gun” engine before shut down: This practice causes incompletelyburned fuel to remove oil film from cylinder walls and dilute lubricant in
crankcase.

If power-assist feature should fail
for any reason, it would require
greater effort to apply service
brake. If power assist fails, stop
as soon as possible. Do not drive
the handler until problem has
been corrected.
Always move parking brake switch
to “On” position before leaving
cab. Never stop engine while
traveling. Parking brake will be
fully-applied and unit could stop
abruptly. A sudden stop could
cause load loss.
With the engine running and the parking brake switch “Off”, parking brakes are
disengaged. Moving the switch to “On” releases hydraulic pressure to apply the
parking brakes. With switch in “On” position, the transmission will not engage
forward or reverse.
Always ensure that transmission
control lever is in neutral before
releasing park brake. Releasing
park brake in either forward or
reverse could cause the machine
to move abruptly.

maneuverability in close quarters.
• 4-wheel crab steering allows the machine to move
sideways at an angle.
• 2-wheel front steer is used for high speed travel.
• It is imperative that the operator practice maneuvering the handler in a
safe, open area to become thoroughly familiar with steering response and
clearance required for fork swing and load when turning.
Be alert for any increase in effort
needed to steer. If any difference
is noted, notify maintenance
personnel immediately. If power
assist feature should fail for any
reason, IT WOULD BECOME VERY
DIFFICULT TO STEER. For this
reason it is extremely important
that you NEVER TURN ENGINE OFF
WHILE TRAVELING. In the event
power steering fails, stop as soon
as possible. Do not drive handler
until problem has been corrected.
Use only 2-wheel steer when
traveling at high speeds. Never use
4-wheel circle steer at high speeds,
sharp turns could cause machine
roll-over.

General
This model material handler is equipped with a powershift transmission.
With this type of transmission, the operator simply selects a gear, selects
the direction of travel, releases brakes and depresses the accelerator pedal
to move the handler.
Operation
Gear Selection: Gear selection is accomplished by rotating the twist grip
handle on the transmission control lever. It is best to begin travel in a lower
gear, however the machine will move away from rest in any gear. Upshifts are
most smoothly accomplished by lifting off the throttle pedal when shifting.
Caution should be taken of downshifting to ensure that the ground speed of
the material handler has slowed sufficiently so as not to over-speed the engine.
DRIVE TRAIN
Select the appropriate gear for the task being performed. Use a lower gear
when transporting a load. Use a higher gear only when traveling longer distances
without a load. When traveling through deep mud, or up slopes, use a lower
gear. Downshift a gear when traveling down a long hill. Use the service brakes,
if necessary, to prevent over-speeding the engine.
Direction of Travel: Direction of travel is selected by moving the transmission
control lever towards the front of the machine for forward travel, and towards
the rear of the machine for reverse travel. Neutral is selected by moving the
transmission control lever to the center position. If neutral is selected while the
machine is moving, the machine will continue rolling in the direction of travel.
Always bring the machine to a complete stop before changing direction of travel.
This will prevent damage to the transmission or torque converter.
Forward or reverse travel can be selected while in any gear.
WARNING
!
Bring handler to a complete stop
before shifting transmission
control lever. A sudden change in
direction of travel could reduce
stability and/or cause load to shift
or fall.

LEVELING THE HANDLER
WARNING
!
WARNING
!
“Leveling” means positioning the handler so that it is level from side to side
(left to right). A level indicator is located in upper right corner of front window
frame to permit operator to determine whether the handler frame is level.
There are four very important things to remember about handler leveling:
1. Never engage a load or lift a load more than 1.2m (four feet) above
ground unless handler is level.
2. A handler with the boom raised and/or an attachment installed is a
partially-loaded handler.
3. Once the handler frame is level and the operator has raised a load
more than 1.2m (four feet) above ground, it must not be moved from this
position if such movement could change the level condition. Do not use
sway to level handler with load more than 1.2m (four feet) above ground.
4. The combination of side tilt and load could cause the handler to tip over.
Level the handler:
The surface which will support the handler can be leveled. This method must
be chosen if it will be necessary to move the handler from its position after
the load has been raised over 1.2m (four feet) from ground AND such
movement could change the level condition.
Raising the boom (loaded or
unloaded) when handler is
leaning to one side could cause
machine to tip over with little or
no warning and cause serious
injury or death.
Remember: The supporting surface must be large enough, smooth enough
and firm enough to keep the handler level when it is moved from its position.
The handler may be leveled by means of the frame-leveling system. This
method may be chosen when it will not be necessary to move the handler
from its position after the load has been raised above 1.2m (four feet) from
ground - OR - when such movement will not change the level condition of the
handler.
Always determine best position for handler to raise load from its present
location and also to position load at its destination. THEN determine which
method of leveling will be required at each location.
FINALLY, consider terrain between present location of load and its
destination. Never attempt to transport a load across terrain which could
cause handler to tip over.
Leveling Handler Frame:
The handler is designed to permit tilting main frame 10° to left or right to
compensate for uneven ground conditions.
Leveling Procedure:
Position machine in best location to lift or place load, position forward/
reverse lever in neutral and apply parking brake. Observe level indicator
to determine whether machine must be leveled and level machine with
the machine level lever.
Always move boom to carry
position (horizontal or below)
before leveling frame. Attempting
to level machine with boom
raised could cause it to tip over.
If handler cannot be leveled
using leveling system, do not
attempt to raise or place load.
Have surface leveled.

OPERATING PROCEDURE & TECHNIQUES
Hydraulic Controls
All boom and attachment movements are governed by hydraulic controls. Rapid,
jerky operation of hydraulic controls will cause rapid, jerky movement of the
load. Such movements can cause the load to shift or fall or may cause the
machine to tip over.
Feathering
Feathering is a control operation technique used for smooth operation. To feather
controls, move control lever very slowly until function begins to move, then
gradually move lever further until function is moving at desired speed. Gradually
move lever toward “Neutral” as load approaches destination. Continue to reduce
load speed to bring load to a smooth stop. Feathering effect can be increased
by reducing engine speed at beginning and near end of load movement.
Boom Control Joystick
The boom control joystick can be positioned to activate individual boom
movements or combinations of boom movements as illustrated:

UNDERSTANDING RATED CAPACITY CHARTS
Rated Capacity Chart
The rated capacity chart, located on dashboard, indicates maximum load
capacities for handlers equipped with G
attachment combinations. These capacities
other attachment combinations except as stated on the capacity chart.
Figure 12-3
Instructions
TWO METHODS OF USING THE CAPACITY CHART.
SAMPLE ONLY - USE CHART IN CAB
Method 1
1. The operator must determine:
BOOM EXTENSIONNUMBER where the load
is to be placed.
BOOM ANGLE where the load is to be
placed.
2. On the capacity chart, find the arc for the boom
extension number, and follow it down to the boom
angle.
3. The number in the load zone where these two cross
is the maximum capacity for this lift. If the two cross
at a division between zones, the smaller number
must be used.
Method 2
1. The operator must determine:
HEIGHT where the load is to be placed.
DISTANCE from the front of the machine
where the load is to be placed.
2. On the capacity chart, find the line for the height and
follow it over to the distance.
3. The number in the load zone where the two cross is
the maximum capacity for this lift. If the two cross
at a division between zones, the smaller number
must be used.
For each method, the number in the load zone must be
equal to or greater than the weight of the load to be
lifted. Determine the limits of the load zone on the
capacity chart by boom angle AND boom extension number.
Keep the load within theses limits.
BACK
9151-3207 REV.-
TIPOVER HAZARD. Failure to comply with
instructions could result in death or serious
injury.
The operator MUST:
1. Make sure the handler is on a firm, level surface
before lifting or placing a load.
2. Make sure that the capacity charts are for the
appropriate Gradall model.
3. Make sure that the Part Numver shown on the
attachment's Serial Number Plate matches the Part
Number shown on the capacity chart.
4. Be sure of the WEIGHT of the load to be lifted.
See page 13-2 for instructions
on how to read capacity charts.
All loads shown on rated capacity
chart are based on machine being
on firm, level ground; the forks
being positioned evenly on
carriage; the load being centered
on forks; proper size tires being
properly inflated; and the handler
being in good operating condition.
Numbers at left side of sample chart represent elevation to top of horizontal
fork as measured from level ground (in feet). Elevation relates to dimension “A”
shown on serial number plate inside operator’s cab.
Boom Extension
Numbers across bottom of sample chart and numbers parallel to boom represent
boom reach as measured from front of front tires to extended position.
Number decals on boom relate directly to boom extension. The largest number
which can be read from operator’s seat indicates total boom extension and
must be matched with boom angle to determine load capacity.
Boom extension relates to dimension “D” shown on serial number plate.
Boom Angle
Numbers shown at ends of angled lines represent angle of boom to horizontal
as measured from horizontal. Maximum angles are -9° below horizontal with
boom fully lowered to 70° above horizontal with boom fully raised.
A boom angle indicator is located on left side of boom-section 1 to show boom
angle. Be sure machine is level from front to rear or indicator will provide
incorrect reading.
13.0
UNDERSTANDING RATED CAPACITY CHARTS
Load Center
Loads shown on rated capacity chart are based on the load center being
610mm (two feet) above and 610mm (two feet) forward of surfaces of
horizontal forks.
The load center of a load is the center of gravity of the load. For regularlyshaped loads of the same material, such as a pallet of blocks, the center of
gravity can be located by measuring the load to find its center. For irregular
loads, or loads of dissimilar materials, keep the heaviest part of the load as
close to the heel of the forks as possible.
In all cases, the load center must be centered between the forks.
Load Limits
Some capacities shown on the rated capacity chart are based on machine stability
and some are based on hydraulic lift capacity.
Items needed to Use a Capacity Chart
There are five items you must know and/or have in order to properly use a
Capacity Chart:
1.The weight of the load to be lifted
2.The angle of the boom
3.How much boom extension will be needed
4.The proper Capacity Chart
5.A Gradall-approved Attachment
Every Gradall attachment comes with its own Identification Plate. This Plate
has the Attachment Serial Number, Part Number, Attachment Capacity and
Attachment Weight stamped on it. Make sure that the Capacity Chart you
are using matches the attachment exactly. This may be done by matching
the attachment part number on the Capacity Chart to the part number
stamped on the Identification Plate. The Machine Serial Number Plate is
mounted inside the cab and lists all standard attachments that may be used
with the machine by part number, at the time it was shipped from the factory.
Be aware that a specific Capacity Chart must not only match the attachment,
but also the machine model.
WARNING
!
Exceeding load limits can cause
damage, or, in some cases, cause
the machine to tip over.
NOTE!
Some attachments may not be
approved for use with certain
machine models.
The boom angle can be determined by looking at the angle indicator mounted
on the side of the boom (see figure 12-5).
The boom extension can be determined by looking at the second boom section.
As the second boom section slides out of the main boom, numbers are
revealed starting with 1. Each number represents approximately 5’ of total
boom extension (see figure 12-5). It is important to remember that these
numbers are designed to be read from the operator’s seat only!

UNDERSTANDING RATED CAPACITY CHARTS
How to read a Capacity Chart
When reading the capacity chart you must check to be sure the correct model
number is listed (see figure 12-6). The next thing to look for is that the part
number of your attachment is listed under the “Use With” section.
Identify and find the amount of boom extension required, along with the
angle of the boom. Trace the boom extension arc down until it intersects
with the appropriate boom angle. If the intersection of the boom extension
arc and the boom angle line occur within a weight region, the value within
that region is the maximum capacity for that particular lift. If the intersection
occurs on a bold line separating capacity regions, the smaller of the two
values must be used. The regions are clearly marked with heavier outlines
as shown on page 12.4. If you do not have the correct capacity chart for
your machine and/or attachment, contact your Distributor or Gradall to order
one.
Example (this is for instructional purpose only - use capacity chart
located in your cab):
A contractor has purchased a TF6-42 with the 48” Slope Piler Carriage
Attachment (see figure 12-6). He knows his attachment may be used with
this model since the attachment part number, 9140-5101, matches the
attachment part number stamped on the machine Serial Number Plate. He
also knows that the Capacity Chart is correct since it is clearly marked for
use with a TF6-42 and that the attachment he is using is listed at the bottom
by part number. He has determined the weight of the load to be lifted is 400
lbs. and that he needs to place the load at a boom extension of 6 at a boom
angle of 20°. By tracing the boom extension arc down to where the 20° line
intersects it, the contractor can see that the maximum weight he can lift is
800 lbs. In this case, he may lift the load.

Approved Attachments
Several JLG/GRADALL-approved attachments are available for use with your
material handler. Contact your JLG/GRADALL Distributor or JLG/Gradall for
information on approved attachments designed to solve special material
handling problems.
The serial number plate lists attachments approved for use with your
Transformer Series Material Handler. However, there may be additional approved
attachments available. Contact your JLG/GRADALL Distributor for further
information.
Non-Approved Attachments
Do not use non-approved attachments for the following reasons:
• JLG/GRADALL cannot establish range and capacity limitations for “will fit”,
homemade, altered, or other non-approved attachments.
• An overextended or overloaded handler can tip over with little or no warning
and cause serious injury or death to the operator and/or those working near
the handler.
Attachments which have not been
approved for use with your handler
could cause machine damage or
an accident resulting in injury or
death.
• JLG/GRADALL cannot assure the ability of a non-approved attachment to
perform its intended function safely.
• Non-approved attachments may cause structural or other damage to the
handler. Such damage could cause dangerous operating conditions resulting
in serious injury or death.
Carriage/Fork Capacities
The standard carriage/fork capacity chart (located on the dashboard) indicates
maximum reach and load capacities for handlers equipped with an approved
carriage/fork combination. These limitations apply to standard, JLG/
GRADALL-approved carriage/fork combinations, except as stated on
the capacity chart.
Non-standard carriage/fork combinations (greater or lesser capacity) may be
furnished by JLG/GRADALL at customer’s request or may be available for
installation because they were furnished for a different application.
If a carriage/fork combination of lesser capacity is used, the overall machinecapacity is reduced to carriage/fork capacity as indicated on carriage/fork
serial number plate.
The capacity of forklift, attachment
and fork combination may be less
than the capacity shown on
attachment. Consult forklift
nameplate and also ensure forks
are of proper size.
Forks rated less than the
attachment capacity decrease
capacity of attachment to that of
forks. Forks rated more than
attachment capacity do not
increase attachment capacity.
15.0
If a carriage/fork combination of greater capacity is used, the overall machine
capacity may be reduced because of additional attachment weight and/or other
considerations. Contact your local JLG/GRADALL Distributor to determine
capacity limitations.
Other Attachment Capacities
A serial number/capacity plate is attached to all JLG/GRADALL-furnished
attachments. Do not assume that any JLG/GRADALL attachment may be
used on any JLG/GRADALL Material Handler.
ATTACHMENTS
WARNING
!
First, check the listing of approved attachments on handler serial number
plate. If the attachment in question is not included in the list, contact your
local JLG/GRADALL Distributor to check whether or not the attachment is
approved.
Next, if the attachment is approved for use with your handler, compare
maximum capacity from attachment serial number plate and value stamped
on forks to maximum capacity for that attachment as indicated on material
handler serial number plate. The smallest of these values is correct for
your handler
Attachment Operation
Operation of the handler equipped with carriage/fork combination is covered in
the GRADALL Material Handler Safety Manual and this Manual.

serial number plate. However, maximum lift capacity applies only to certain
areas within boom extension/elevation pattern of handler/slope piler carriage
combination. A separate capacity chart must be used for handlers equipped
with slope piler carriage. Study and understand this chart before attempting
to handle a load with slope piler carriage.
PRECAUTIONS
• Read and understand
additional capacity information
under “Capacity” heading.
• Always level forks
(horizontally) before swinging
load to side. Swinging
unlevel forks could result
in load slipping from forks.
• Because the swing forks can
swing the load to the side, it is
especially important that the
handler be level when
handling a load more than
1.2m (four feet) above
ground. See page 11.0.
PRECAUTIONS
• Level handler before tilting
carriage to engage load.
• Always level handler before
lifting a load more than
1.2m (four feet) above
ground. See page 11.0.

Do not handle a load with Slope
Piler Carriage attachment until
you study and understand the
“Slope Piler Carriage Capacity
Chart.” If your handler does not
have a “Slope Piler Carriage
Capacity Chart,” ask your
supervisor to get one before
using the attachment.
A side load or a swinging
load could cause the
handler to tip over and/or
damage the boom.
• Tilt carriage to left or right to align forks with load and engage load.
• Raise load slightly and then level carriage.
• Travel with load lowered to travel position 1.2m (4 feet) or less above ground.
Truss Boom & Truss Boom with Winch
Capacity:
Maximum capacity for the truss boom (with or without winch) is shown on
attachment serial number plate. However, maximum lift capacity applies only
to certain areas within boom extension/elevation pattern of handler/truss boom
combination. A separate capacity chart must be used for handlers equipped
with truss boom. Study and understand this chart before attempting to handle
a load with truss boom.
Observe the following Special Precautions:
• Never drag the load; lift vertically.
• Use tag line to guide and steady a suspended load. Tag lines must be
long enough to keep helpers clear of load and handler.
• Beware of wind. Wind can cause a suspended load to swing and
cause dangerous side loads - even with tag lines.
ATTACHMENTS
WARNING
!
PRECAUTIONS
• Because the truss boom
extends the reach of the
handler, maximum load
capacity is reduced.
• Because of extended reach, it
is especially important to level
the handler before lifting a
load. See page 11.0.
• Travel with load and boom
lowered to travel position
1.2m (4 feet) or less above
ground.
• Always lower load to rest
before leaving handler.
• Start, travel, turn, and stop slowly to prevent load from swinging.
• Weight of all rigging (slings, etc.) must be included as part of load.
• Do not attempt to use handler frame-leveling to compensate for load swing.

MOVING HANDLER IN EMERGENCY
The following information assumes the handler cannot be moved under
its own power.
Before moving the handler, read all of the following information to understand
options available. Then select the appropriate method.
The steering system permits manual steering if engine or power assist
feature fails.
Remember:
• Although manual steering is possible without power assist, steering will be
slow and will require much greater force.
• Response to manual steering will be increased if parking brake is released
and front axle drive is bypassed, permitting front wheels to roll.
MOVING SHORT DISTANCES
If it is only necessary to move handler a short distance less than 30m (100
feet), it is permissible to use a vehicle of sufficient capacity to tow the unit
with no previous preparation. Drive wheels will not roll. If the unit must be
moved more than 30m (100 feet), but less than 182m (200 yards), it is
permissible to use a vehicle of sufficient capacity to tow unit after you:
• Release parking brake. See page 18.1.
MOVING LONGER DISTANCES
If the handler must be moved more than 182m (200 yards), it must be
loaded on to a trailer of sufficient capacity.

DAILY REAR AXLE LOCK-OUT TEST PROCEDURE
WARNING
!
WARNING
!
TESTING REAR AXLE LOCKING SYSTEM (perform daily test)
The TF6-42 is equipped with a rear axle locking system for use while in work
platform mode. In this mode, when the boom is raised above 50 degrees, a
cylinder at the rear will lock, preventing oscillation of the rear axle. With the
boom below this angle the cylinder will allow the rear axle to oscillate freely.
When the machine is in material handler mode, the rear axle cannot be locked,
the rear axle will always oscillate freely.
After attaching the work platform and connecting the electrical cables, the
work platform mode should be checked to ensure proper operation of the rear
axle stabilization locking system.
Checking the rear axle locking system in work platform mode
Perform the following check from the work platform. No material, equipment,
or personnel other than the operator should be on the platform during the
performance of this test. This test will require the use of an assistant on the
ground.
1.)Position Control Station Selector Key switch to Platform.
2.)Start the machine from the platform. Raise the boom to approximately
zero degrees (horizontal) boom angle.
3.)Locate an eight inch curb, and drive the machine’s left front wheel up
on the curb, leaving all other wheels off the curb.
4.)Level the machine by operating the Sway function. No wheel should
leave the ground.
5.)Back the left front wheel off the curb. Again, no wheel should leave the
ground.
6.)Drive the left front wheel back up on the curb, and release the drive
controller. Use the sway function to level the machine.
7.)While keeping clear of the rear wheels, have an assistant check that
the red LED on the proximity switch at the right rear of the machine
is “glowing”. Have the assistant disconnect the proximity switch from
the wire harness. The red LED should be “OFF” (see figure 7-1).
Should the machine fail any part of
this check, immediately discontinue
the checking process. Do not use
the machine. Place a “DO NOT
OPERATE” tag on the machine, and
have it repaired.
Do not raise boom above 5 degrees
for steps 1 through 9 of this check.
P7.0
8.)Back the left front wheel off the curb. The rear axle should be locked
and one wheel should be off the ground. Set the park brake.
9.)Again, staying clear of wheels, have the assistant reconnect the
proximity switch to the wire harness. The raised wheel should
immediately return to the ground.
10.)If the machine has passed all of these checks, place the machine on
level ground, set the park brake and raise the boom above 50 degrees.
11.)Have the assistant check that the red LED on the proximity switch at
the right rear of the machine is “OFF”.

4
Controls and Indicators
This machine is equipped with a work platform. The intended purpose is to
position personnel with their tools and supplies at positions above ground
level, and can be used to reach work areas located above machinery or
equipment.
The platform has an operator Control Station. From this control station, the
operator can drive and steer the machine in both forward and reverse directions.
The operator can raise or lower the boom or rotate the platform left or right.
The lift is not intended to be used to lift material other than supplies which
personnel in the platform require to do their job. Supplies or tools which extend
outside the platform are prohibited unless written approval has been obtained
through JLG/Gradall. It must not be used as a forklift, crane, support for
overhead structure, or to push or pull another object.
The speeds of boom functions are variable from zero to maximum speed
depending upon the position of the function speed control. Functions controlled
by toggle switches are either on or off. A foot operated switch in the platform
must be depressed before any controls will function and provides a means of
emergency stop when the operators foot is removed from the footswitch.
The unrestricted capacity of the lift is 500 lbs. (230 kg). This means that with
a platform load of 500 lbs. (230 kg) or less, the platform may be positioned
anywhere the boom will reach, with the machine level and on a smooth, firm,
and level surface and tires properly inflated.

PLATFORM CONTROLS AND INDICATORS
Engine Start/Auxiliary Power:
Engine Start
Push “UP” on Engine Start/Auxiliary Power switch to start engine. If engine fails
to start within 20 seconds, release Engine Start/Auxiliary Power switch and
allow starting motor to cool for a few minutes before trying again. For engine
starting, the footswitch must be in the released (up) position.
Auxiliary Power
A toggle-type Engine Start/Auxiliary Power control switch energizes the
electrically operated hydraulic pump, when actuated. (Switch must be held
“DOWN” for duration of auxiliary pump use.) The auxiliary pump functions to
provide sufficient oil flow to operate the basic machine functions should the
main pump or engine fail. The auxiliary pump will operate boom lift, telescope
and rotate. It should be noted that the functions will operate at a slower than
normal rate.
Auxiliary power is primarily intended for platform lowering in the event of primary
power failure. However, auxiliary power may be used for platform positioning
when operating in close quarters in the following sequence:
1. Position CONTROL STATION SELECT switch to PLATFORM.
2. Position POWER/EMERGENCY STOP switch to ON.
3. Depress and hold footswitch.
4. Position AUXILIARY POWER switch to ON and hold.
5. Operate appropriate control switch or lever for desired function and hold.
6. Release AUXILIARY POWER switch, selected control switch or lever, and
footswitch.
7. Position POWER/EMERGENCY STOP switch to OFF.
Footswitch:
This feature makes it necessary to depress the footswitch to allow operation
of the platform controls.
Function Speed:
To avoid serious injury, do not
remove, modify or disable the
footswitch by blocking or any other
means.
NOTE!
The main function of auxiliary
power is to lower the platform in
the event of primary power
failure.
NOTE!
Footswitch must be depressed prior
to activating any function control,
otherwise the function will not
operate.
Footswitch must be adjusted so that
functions will operate when pedal is
approximately at its center of travel.
If switch operates within last 1/4”
of travel, top or bottom, it should
be adjusted.
P8.2
The knob provides variable speed control of all boom functions grouped together
to the right of the knob. For smoothest operation of these functions, use two
hands: rotate the knob counterclockwise to the slowest position, select the
function switch, and while holding the switch on, rotate the knob to the desired
speed. To achieve a smooth stop, rotate the knob counterclockwise to a slow
speed prior to letting go of the function switch. Rotating the knob fully
counterclockwise until a click is heard puts all controls, including drive, main
lift, and swing into “creep” speed. This slow speed is used for fine positioning
of the platform when close to obstacles. A snail symbol is used to indicate
“creep” speed and is shown at the Function Speed knob as well as near the
proportional controllers to act as a reminder.
Horn:
A push-type HORN switch activates an audible warning device when pressed.
Lights Indicator:
Illuminated when lights are turned on.
NOTE!
When the boom is raised
approximately 7 degrees above
horizontal, the high drive function
will automatically switch to low
drive. This also occurs when
Function Speed Control is set to
creep.
To avoid serious injury, do not
operate machine if any control
levers or toggle switches controlling
platform movement do not return
to the off position when released.
PLATFORM CONTROLS AND INDICATORS
Low Fuel Indicator:
When illuminated the fuel tank is 1/8 full or less. When the light first turns on,
there are approximately four usable gallons of fuel remaining.
Platform Leveling Override:
The PLATFORM LEVEL control switch allows the operator to adjust the level of the
platform by positioning the switch to UP or DOWN.
Platform Rotate:
The PLATFORM ROTATE control switch allows the operator to rotate the basket to
the left or right when positioned to the desired direction.
Power/Emergency Stop Switch:
An ON-OFF POWER/EMERGENCY STOP switch and a separate ENGINE START/
AUXILIARY POWER toggle switch on the platform console supply electrical power
to the starter solenoid, when the power/emergency stop switch is pulled out to
the “ON” position and the ENGINE START switch is pushed forward. Push in to
shut off engine and remove power from the controls. The power/emergency
stop switch must be pulled out in the cab to operate either from the cab or
platform control. This allows the machine to be shut down in emergency
situations.
Steer Select:
The center switch position gives conventional front wheel steering with the rear
wheels unaffected. This is the best position for driving at maximum speeds. The
forward position is for “crab” steering. When in this mode both front and rear
axles steer in the same direction, which allows the chassis to move sideways.
This can be used for positioning the machine in aisle ways or against buildings.
The back switch position is for “coordinated” steering. In this mode the front and
rear axles steer in the opposite directions to produce the tightest turning circle
for maneuvering in confined areas. If the steer select switch located in the cab is
not set to front wheel steer, the platform steer select switch will not change the
steering mode.
Sway Control Switch:
The sway control switch allows the operator to level the machine. Operator must
position machine and level prior to raising work platform.
Tilt Alarm Warning Light:
This orange illuminator indicates that the chassis is on a slope (over 5 degrees).
If illuminated when boom is raised or extended, retract and lower to below
horizontal then reposition machine so that it is level before extending boom or
raising boom above horizontal. If the boom is above horizontal and the machine
is on a 5 degree slope, an alarm will sound and CREEP mode is automatically
activated.
