Electrical Hazard
■ Electrical Hazard Warning
DANGER
THE TL39T AERIAL WORK PLATFORM, IN STANDARD CONFIGURATION, IS
NOT ELECTRICALLY INSULATED.
If the plat form, booms, or any other conductive part of a TL39T contacts a high-voltage electrical
conductor, the result can be SERIOUS INJURY or DEATH for persons on or near the machine.
GO NO CLOSER THAN THE MINIMUM SAFE APPROACH
DISTANCES (M.S.A.D) - AS OUTLINED IN TABLE 1. AND FIGURE 3.,
ON THE NEXT PAGE.
Be sure to allow for sag and sway in the wires and the work platform.
If a TL39T comes in contact with a live electrical conductor, the entire machine can be charged.
If that happens, you should re main on the machine and not contact any other structure or object within
reach. That includes the ground, adjacent buildings, poles, and any object not a part of the TL39T.
Such contact could make your body a conductor to the other object creating an electrical shock hazard
resulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the TL39T until you are sure the electricity has been turned off.
If a TL39T is in contact with a live conductor, the platform operator MUST warn others on the ground
in the vicinity of the TL39T to STAY AWAY from the machine, since their bodies can also form a path
for electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and
DEATH.
DO NOT attempt to operate the TL39T ground controls when the platform, booms, or any other conducting
part of a TL39T is in contact with electrical wires or if there is an immediate danger of such contact.
Regard all conductors as energized.
Personnel working on or near a TL39T must be continuously aware of electrical hazards, recognizing that
SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

● Presence of unauthorized persons.
● Other possible unsafe conditions.
location according to ANSI/NFPA 505.
Any TL39T operated in a hazardous location must
be approved and of the type required by ANSI/
NFPA 505.
While operating the MHP a recommended safety
practice is to have trained and qualied personnel
in the immediate work area of the TL39T to:
● Help in case of an emergency.
● Operate emergency controls as required.
● Watch for loss of control by platform operator.
● Warn the operator of any obstructions or
hazards that may not be obvious to them.
● Watch for soft terrain, sloping surfaces, drop-
offs, etc., where stability could be jeopardized.
● Watch for bystanders and never allow anyone
to be under, or to reach through the booms
while operating the aerial platform.
! DANGER
Pinch points may exist between moving
components. Death or serious injury can
result from becoming trapped between
components, buildings, structures, or other
obstacles. Make sure there is sufcient
clearance around the machine before moving
the chassis, booms, or platform. Allow
sufcient room and time to stop movement
to avoid contact with structures or other
hazards.
Keep ground personnel from under the platform
when the plat form 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.
Always look in the direction of travel. Drive with
care and at speeds compatible with the work-place
conditions. Use caution when driving over rough
ground, on slopes, and when turning.
Do not engage in any form of “horseplay” or “stunt
driving” while operating the TL39T.
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.
Before the TL39T is used, determine the hazard
classication of any particular atmosphere or
page 1-2 Rev C
1. Safety
Never steady the platform by positioning it against
another platform.
Do not operate an TL39T that is damaged or not
functioning properly. Do not use the MHP until
the machine has been repaired by a qualied
maintenance person.
Do not operate a TL39T that does not have all its
decals and placards attached and legible.
Watch for by stand ers 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.
■ Operation
If you encounter any suspected malfunction of the
aerial platform, or any hazard or potentially unsafe
condition relating to capacity, intendeduse, or safe
operation, cease operation immediately and seek
assistance from management.
Use three points of sup port when get ting on or off
the platform (two hands and one foot or a similar
set of points). Keep the platform clean.
Do not operate the TL39T from a position on trucks,
trailers, railway cars, oating vesels, scaffolds,
or similar equipment unless the application is
approved in writing by Snorkel.
Care shall be taken to prevent rope, electric cords,
and hoses, etc., from becoming entangled in the
aerial platform. If the platform or elevating assembly
becomes caught, snagged, or otherwise prevented
from normal motion by an adjacent structure or
other obstacle 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.
Under normal working conditions it is best not to
transfer from the platform to another structure or
vice versa, unless that is the safest way to do the
job. Each situation must be judged separately
taking the work environment into account. The
following guidelines apply:
1. Where possible, place the work platform over
a roof or walking structure to do the transfer.
2. Transfer your anchorage from one structure to
another before you step across.
Maintain a rm footing on the platform oor. Operate
the controls slowly and deliberately to avoid jerky
and erratic operation. Always stop the controls in
neutral before going in the opposite direction.
Do not dismount while the platform is in motion or
jump off the machine.
Do not start until all personnel are clearly away from
the machine.
Never cover the oor grating or otherwise obstruct
your view below. Make sure the area below the
platform is free of personnel before lowering.
■ Tipover and Falling Hazards
Operate the MHP only on a rm, at, level surface
capable of withstanding all load forces imposed by
the TL39T in all operating conditions.
! DANGER
The MHP can tip over if it becomes unstable.
Death or serious injury can result from a
tip-over accident. Do not drive or position
the MHP platform for elevated use near any
drop-ff, hole, slope, soft or uneven ground, or
other tip-over hazard.
3. Remember, you might be departing the work
platform to a structure where fall arrest is
required.
4. Do not climb over or through the guardrails.
Use the platform entrance.
All platform occupants MUST wear and use fall
restraint. At tach fall restraints to the platform
lanyard anchor points.
Do not exceed the unrestricted platform capacity as
indicated on the capacity placard at the entrance
to the platform. Do not carry loads from any point
outside of the platform.
Make sure that all protective guards, cowlings, and
doors are in place and secure. Be sure the guardrail
system, including the gate, is in place and secure.
Do not climb on the guardrails or use ladders,
planks, or other devices to extend or increase your
work position from the platform.
Do not use the MHP as a crane, hoist, or jack, or for
any other purpose other than to position personnel,
their tools, and materials.
Do not operate the TL39T in winds, or wind gusts,

Push the test button on the RCD/ELCB device and
the power outlet at the platform should not work.
! CAUTION
RCD/ELCB devices should only be replaced
by a qualied electrician.
Check both positions of each switch.
For correct operating procedures see the
”Operation” chapter 8.
NOTE
Pay particular attention to the Emergency Stop
switch to see that it turns the TL39T engine off
when struck.
Pay particular attention to the platform Enable
switch or the platform foot switch (if that option is
tted) to see that the platform moving switches are
deactivated when the either switch is not operated.
At the completion of the above section the unit can
be returned to the stowed position.
■ Placards and Decals
Look to see that all placards and decals are in
place and legible. Clean dirty or obscured decals
with soap and water and a soft lint cloth. Replace
any missing or illegible placards or decals before
placing the TL39T into service for the daily work
shift.
NOTE:
Owing to manufacturing variances and customer
preferences there may be some small differences
in the decal layout on specic machines.
NOTE Safety Decals:
Details of the safety decals and their locations are
listed in the Safety chapter(s) near the beginning of
this manual.
■ Placards and Decals

8. Operation
■ Operating Procedures
This chapter explains how to properly start and
operate an TL39T. Read and understand all the
previous chapters in this manual before you begin
to operate an TL39T.
! CAUTION
Do not leave the TL39T engine running if you
are sandblasting. Sand drawn into the air
intake can erode engine parts.
■ Control Stations
An TL39T can be operated from the ground control
box or from the platform control box. There are
basically two differences between ground control
and platform control operations, both are safety
related:
1. The ground control station can override
the platform control station 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.
Figure 8.1 - Ground Control Box Emergency
Stop Switch Location.
Figure 8.2 - Platform Control Box Emergency
Stop Switch Location.
2. The stabilisers can only be selected from
the ground control station and only when the
booms are in the stowed position.
! DANGER
The TL39T is not Electrically Insulated in its
standard form.
Death or Serious Injury to operating
personnel, can occur if the machine should
come into contact with energized electrical
wires during operation.
DO NOT attempt to operate the TL39T ground
controls if the platform, booms, or any other
conducting part of an TL39T is in contact with
energized electrical wires or if there is an
immediate danger of such contact.
NOTE
See the “Electrical Hazard” section, in this
manual for a complete explanation of the hazards
concerning electricity.
■ Emergency Stopping
NOTE
For a complete discussion of the Emergency
Stop switches, see “Controls” chapter 6, and
“Emergency Operation” chapter 9 in this manual.
■ Operation Considerations
To use this chapter, rst decide whether you will be
starting and operating the TL39T from the ground
control box or the platform control box.
■ Stabiliser Operation
NOTE: All Stabiliser Operations
The stabilisers will only function when the platform
is fully lowered and the booms are stowed. Once
the booms are raised the stabilisers will not
operate.
Once the platform is raised the stabilisers cannot
be set or adjusted.
To stop an TL39T, press the red EMERGENCY
STOP button in, on either the ground control box or
the platform control box
■ Emergency Stopping
Rev C page 8-1
8. Operation
Before operating the stabilisers check to see that
the ground conditions under the four stabiliser pads
is rm, stable and unobstructed.
! DANGER
If the platform is up and the ground
compresses unevenly under different
stabiliser pads the MHP might fall over
causing serious injury or death. Check the
level bubble frequently during operation.
If any movement of the bubble occurs,
immediately lower the platform and readjust
the stabilisers to re-center the bubble in the
ring.
When using the stabilisers always check that all
four are rmly on the ground and that they are
clear of manhole covers, drains, etc., which may
collapse. If the ground is at all soft, steel plates at
least 300mm x 300mm x 6mm should be placed
under the feet to spread the weight.
Figure 8.3
Lower the rear stabilisers and level the machine
using the level bubble (see Figure 8.4) adjacent to
the control levers.
! DANGER
Death or serious injury can result if an MHP
tips over. Do not use the stabilisers to gain
extra working height, they are not designed
for that purpose. At least one of the stabilisers
should raise the MHP above the ground - use
the other three to level the MHP as necessary.
NOTE: Operating the Stabilisers
Before you can operate the stabilisers you need
to start the engine. See “Starting From Ground
Control Box” on page 3.
❑ Using the manual stabiliser valves
Ensure the Boom/Stabiliser Switch (item on
the ground control box) (see Figure 8.7) is set to
stabiliser.
Activate the stabilisers with the valve levers
(down-wards). (see Figure 8.3)
NOTE:
Figure 8.4
! WARNING
When levelling the machine in either the
manual or automatic mode care is required
to ensure that all the foot plates are rmly
on the ground, the machine is level and the
lift enable light is on before entering the
platform.
❑ Raising the manually operated stabilisers
Raising the stabilisers is the reverse of setting the
stabilisers.
Ensure that the Boom/Stabiliser Switch is is set to
stabiliser.
Ensure that the front stabilisers are lowered rst to
prevent damage to the jockey wheel.
page 8-2 Rev C
Raise the stabilisers by activating the individual
valve levers (upwards).
NOTE:
Ensure that the rear stabilisers are raised rst to
prevent damage to the jockey wheel.
8. Operation
■ Self levelling stabilisers (Optional)
Figure 8.5 - Auto Level Controls
For units tted with self levelling stabilisers the
following applies:
1. Press and hold down down the auto level
switch
The stabilisers will lower and the machine will
“level” automatically.
NOTE:
Switch is also used to raise the stabilisers to the
stowed position. To do so press and hold switch
in the auto stow direction and all the stabilisers will
raise automatically to the stowed position.
NOTE:
Although this option is primarily designed to
automatically set the stabilisers it is also possible to
set the stabilisers manually.
! IMPORTANT
Failure to remove the boom lock pin before
attempting to raise the booms could result in
damage to the machine.
Remove the pin keeper and then remove the pin
from the boom cra dle lock .
Figure 8.6 - Boom Cradle Lock
■ Starting From Ground Control Box
Before you begin to operate the TL39T from the
ground control box, a qualied operator must
perform the “Pre-operational Inspection” as
described in chapter 7, of this manual.
To start the engine from the ground control box do
the following:
1. Set the Emergency Stop switch to ON (see
Figure 8.7).
❑ Setting the stabilisers manually
1. Operate each switch (see Figure 8.5) to
raise or lower each stabiliser one at a time.
Use the level bubble (see Figure 8.4) to check
the machine is level.
! WARNING
When levelling the machine in either the
manual or automatic mode care is required
to ensure that all the foot plates are rmly
on the ground, the machine is level and the
lift enable light is on before entering the

9. Emergency Operation
■ Emergency Operation Procedures
The following procedures are emergency
procedures only. DO NOT use them for normal
operation. Their purpose is to get the platform and
operator safely to ground when the TL39T will not
start or some other problem keeps the platform
from lowering in the normal way.
■ Emergency Operation Procedures
❑ Operation from platform control box
➠ Ground control station settings
Switch set tings listed in the three steps below must
exist at the ground before emergency operation
procedures will work at the platform control box:
! IMPORTANT
The TL39T has an ENABLE switch tted
to the Upper & Lower control boxes. (see
Chapter 6 for a full explanation of the
operation of this switch).
Some machines will also be tted with a
FOOT OPERATED ENABLE switch.
On those machines tted with the foot switch
option, both the switch on the control box and
the foot switch perform the same function.
However it is assumed that for units tted
with a foot switch this will be the preferred
method of operation.
If the FOOT OPERATED ENABLE SWITCH
option is in stalled on your machine go to
Step 4 - otherwise go to Step 5.

page 10-2 Rev C
11. Options
■ Bi-Energy, Petrol/Diesel / 24V DC
There are various Bi-Energy options available for
the TL39T. The following describes the Petrol/
Diesel / 24V option.
This consists of a combination of both a gasoline
or diesel engine and a 24V DC motor to give a Bienergy option.
Specically a 24V DC motor is mounted on the
column under the left hand side cover. This provides
an alternative power source to the gasoline or
diesel engine.
The DC motor is powered by four “Deep Cy cle
Traction Batteries” mounted 2 each side of the
column and an automatic battery charger that is
also mounted on the column.
❑ DC motor
The DC motor is mounted under the left hand side
cover (see Figure 11.1).
❑ DC motor battery switch
In order to operate the DC motor the 24V DC
battery isolator switch, mounted at the centre rear
of the column, will also need to be switched on (see
Figure 11.3).
Figure 11.3 - DC Motor Battery Isolate Switch
Note - 24V DC Battery Switch
When operating the gasoline/diesel engine the
24V DC battery switch should be turned to the “off”
position.
Figure 11.1 - DC Motor
❑ DC motor operation
A Fuel / Electric switch is used to select either the
gasoline/diesel engine or the DC motor.
This switch is mounted on the front of the lower
control box (see Figure 11.2.1).
❑ Setting the manual stabilisers
In order for the stabilisers to function an additional
switch (see Figure 11.4) needs to be operated.
This switch, mounted adjacent to the stabiliser
valve levers, must be held on in the STABILISER
ENABLED position while the individual stabiliser
valves are operated.
When released it will automatically return to the
STABILISER DISABLED position
Figure 11.4 - Stabiliser Enable Switch
Note: - Stabiliser Enable Switch
This switch is ONLY tted to units that have manual
stabiliser valve levers.
Figure 11.2.1 - Fuel / Electric Switch
If the gasoline/diesel engine is selected [SWITCH
UP] the DC motor will not function and if the DC
motor is selected [SWITCH DOWN] the gasoline/
diesel engine will not run.
Rev C page 11-1
❑ Setting the automatic stabilisers
When the Automatic Stabiliser Option is tted
there is no need to use the stabiliser enable switch
described above.
For automatic stabilizer operation refer to the
Operation Chapter.
11. Options
❑ Operation
Once the DC mode is selected the motor will then
power all the functions in the normal manner,
(excluding the manual stabiliser operation
described above).
The only difference is that the DC motor will only
run when a function is selected e.g. raising a boom.
❑ Batteries
Since the Bi-Energy MHP is powered by “Deep
Cycle Traction Batteries” particular attention should
be paid to the batteries on-board charger to ensure
proper operation.
The batteries are mounted at each side of the
column (see Figures 11.5 and 11.6).
Lead-acid batteries contain sulphuric acid
which will damage eyes or skin on contact.
When working around batteries, ALWAYS
wear a face shield to avoid acid in the eyes.
If acid contacts eyes, ush immediately with
clear water and get medical attention.
Wear rubber gloves and protective clothing
to keep acid off the skin, if acid contacts the
skin, wash off immediately with clear water.
Lead-acid batteries produce ammable and
explosive gasses. NEVER allow smoking,
ames or sparks around batteries.
❑ Battery charger
The Bi-energy MHP is tted with an on-board
charger (see Figure 11.7). The charger
will completely re-charge the batteries and
automatically turn off after the cycle is completed.

The battery charger is t ted with an “interlock”. This
means that during the charging cycle all functions
on the machine are in operative and will remain so
until the charger unit is switched off.
The charging cycle may last from 1 to 12 hours
depending on the state of the batteries.
If the charging cycle should exceed 16 hours
(indicating a fault) the charger will automatically
shut down and the batteries should be checked.

■ Bi-Energy, Petrol/Diesel / 240V AC
Another Bi-Energy option available for the TL39T is
the 240V AC / Petrol/Diesel option described below.
This consists of a combination of both a gasoline
or diesel engine and a 240V AC motor to give a
Bi-energy option.
Specically a 240V AC motor is mounted on the
column under the left hand side cover. This provides
an alternative power source to the gasoline or
diesel engine.
The AC motor is powered from an external AC
power source
❑ AC motor
The AC motor is mounted under the left hand side
cover (see Figure 11.9).
Figure 11.9 - AC Motor
DO NOT allow smoking, ames or sparks
around batteries.
! IMPORTANT
DO ENSURE the side covers are removed/
raised during the charging process to allow
gasses to escape.
❑ Batteries - general maintenance
Al ways keep the batteries clean, free of dirt
and corrosion. A lm on top of the battery can
accelerate discharge.
Cold reduces battery capacity and retards charging.
Heat in creases water usage and can (in extreme
circumstances) result in overcharging.
Use distilled water to rell the batteries. Avoid water
containing metallic solids such as iron.
❑ Batteries - charging
Fully recharge the batteries, immediately after
use. One charging cycle per day is preferred. Fully
charged batteries perform best. The deeper the
discharge, the fewer number of cycles a battery
will deliver. Deep discharges deteriorate the battery
quicker than shallow cycles.
❑ AC motor operation
A Gas/Electric switch is used to select either
the petrol/diesel engine or the AC motor (see
Figure 11.10).
Figure 11.10 - Petrol/Electric Switch
An overly dis charged battery may need to be
cycled a few times before it can fully recover. If
a battery begins to heat before becoming fully
charged, it may be necessary to recharge and
discharge the battery a few times.
The MHP is equiped with an automatic bat tery
Rev C page 11-3
11. Options
❑ AC power connection
In order for the AC motor to operate (when the
petrol/electric switch is in the electric position) an
AC power source must be connected to the MHP
(see Figure 11.11).
Figure 11.11 - AC Power Input Connector
❑ Operation
The same controls are used to stop, start and
operate the electric motor as are used for the
petrol/diesel motor.
If the petrol/electric switch is in “electric mode” but
no AC power source is connected the MHP will
default to petrol operation when the ignition switch
is activated.
❑ Bi-Energy, Hydraulic Oil Tank
■ Other Options
■ Air Line To Platform
This consists of pressure ex yellow hose rated
at 150 psi working pressure, tted with quick
disconnect couplers at each end .
■ Work Lights
Rubber encased work lights can be tted to the
platform guardrails. The lights are swivel mounted
and each has its own switch.
■ Flashing Light
Mounted on the lower boom the ashing light
alerts people that the TL39T is moving. The light
ashes at about one ash per second any time the
MASTER KEY switch is on. There is no ON/OFF
switch for the ashing light, it cannot be turned off
while the MHP15/44 is running.
An option is also available that does al low ON/OFF
switching of the ashing light.
■ Battery Isolate Switch
Isolates the battery power and can be locked into
the off position.
For both Bi-Energy options de scribed an additional
feed line from the hydraulic oil tank is used (see
Figure 11.12).

■ Self Levelling Stabiliser
With this option the stabilisers will ‘self level’
the platform when the auto mode is selected,
alternatively the stabilisers can be used individually
when in the manual mode.
Figure 11.15 - Self Levelling Stabilisers
The foot switch performs the same function as the
standard enable switch. Stepping on the foot switch
is an action that must be performed, at the same
time as another action, to make the booms/platform
move.

■ 10.9 Metre Height Restriction Kit
This kit may be tted to machines manufactured
for the Australian market to comply with Australian
legislation.
■ Spare Wheel
Mounted on the front of the trailer in a recessed
well, this is an ideal option for machines that
regularly travel in isolated country areas.
Figure 11.16 - Spare Wheel
For machines tted with this kit a key switch is
provided on the lower control box.
This switch allows the machine to operate to its
full boom height of 11.5m when the switch is in the
DISABLED position or to the restricted height of
10.9m when the switch is in the ENABLED position

! IMPORTANT
The key MUST NOT be left in the machine by
a qualied operator when the machine is left
unattended.
Note:
The key can only be removed in the 10.9m
restricted mode thus ensuring that it is not able
to be operated at full height by an unqualied
operator.
■ Platform Overload Protection
The load sensing system sounds an alarm and
illuminates a lamp to warn the operator that the
platform is overloaded.
The alarm will sound and the overload lights
(located at both the Lower and Upper control
boxes), will illuminate as soon as the overload point
is reached.
Note:
When the alarm sounds all platform movement is
prevented.
The alarm and function interlock will remain active
until the load is reduced.
