WARNINGS!
1. DO NOT operate this Thieman liftgate without the Owner’s Manual for this model present
on the vehicle and without all decals present and legible, as guides for proper liftgate
operation and maintenance (see the “Decal Maintenance - Inspection and Location of
Decals” section of this manual). For replacement Owner’s Manuals, decals, etc. call
Thieman at 419-586-7727. For the latest manuals and warnings for each liftgate, visit our
website at www.thiemantailgates.com. Note: manuals and warnings update regularly.
2. The vehicle must be securely and properly braked on level ground before using the liftgate.
3. All protective covers and guards must be in place before operating the liftgate.
4. Before using liftgate, check for signs of improper maintenance or damage (unusual noises,
vibrations, fails to operate freely, missing hardware, cracked welds…etc. See the sections
in this manual with “Maintenance” in the title – refer to “Table of Contents” on Page 2).
 DONOTusetheliftiftheseareevident.OnlyanauthorizedThiemandistributorisqualied
to do repairs on the liftgate. DO NOT attempt to do your own repairs or modify this liftgate.
Altering this product will void all warranties and may damage the liftgate or even cause
serious injury. If any repairs, adjustments, or maintenance not covered in this manual are
required, contact your nearest Thieman distributor or call Thieman at 419-586-7727.
5. THIS IS NOT A PERSONNEL LIFT. Because of the pinch point between the platform and
the truck, fall hazards, unstable loads, etc., riding the lift may cause severe personal injury
or death. ALWAYS stay clear of the liftgate when in operation. Do NOT ride the liftgate.
6. Make certain the areas, in which the platform will open or close, are clear before opening
or closing the platform.
7. Use this liftgate ONLY for its intended purpose of loading/unloading cargo between truck
bedandground.ItisNOTtobeusedforanythingotherthanthis.Thegroundisdened
as the surface the truck is parked on.
(Warnings continued on following pages)
IMPROPER OPERATION OF THIS LIFTGATE MAY RESULT IN SERIOUS PERSONAL INJURY
AND/OR DEATH. DO NOT operate this liftgate unless you have been properly instructed and
have read and understood the Owner’s Manual and all of its warnings, operating instructions
and all decals.
The following list of warnings is to be read and understood before operating the TT15
series liftgate. The numbered list begins below and continues on the following pages.
!WARNING

5.
8. DO NOT use this liftgate to load or unload cargo from any elevated surface such as a
dock, sidewalk, raised concrete slab, etc. A truck’s suspension WILL squat under load,
andmaycauseloadstobecomeunstable.Also,thiseectivelychangesthe“bedheight”
of the truck, so the liftgate may not function properly on an elevated surface and may bind
and damage the liftgate. Additionally, if the ENTIRE liftgate platform is not supported by
the elevated surface, this partially supported condition WILL create unintended loads on
the liftgate components and MAY LEAD TO A SUDDEN LIFTGATE FAILURE.
9. DO NOT OVERLOAD THE LIFTGATE. Each liftgate has a specic maximum capacity for
lifting and lowering. The standard maximum rated capacity of the TT15 series liftgates
dierswitheachmodelasfollows:
TT15-1500 lbs. Maximum Load
WARNING note:Special options can lower the maximum rated capacities below
those shown above. Be certain you know what the maximum rated capacity is for your
particular liftgate.
10.NEVERo-centertheload onthe platform,fromsidetosideorawayfromtruckasthis
may overload the liftgate. The center of weight of the load should NEVER be placed
beyond the center of the platform load surface, away from truck. Loads should be placed
closetoplatformedgenearesttruck.Seegure1.
11.NEVERallowanypartoftheloadtoextendbeyondtheedgesoftheplatform’satload
surface. Overhanging objects increase the risks of tipping loads due to unstable loading
or snagging these objects on surroundings and THESE OBJECTS COULD ALSO STRIKE
OR CRUSH OPERATORS OR BYSTANDERS.
12. NEVER step on or place loads on, the ramp portion of any liftgate platform (includes
all ramp styles), unless the platform is lowered completely to the ground and the entire
platform and ramp are supported by the ground.
13. NEVER lift or lower unstable loads.
14. NEVER operate liftgate if platform load surface is slippery.
15. Make certain the areas above and below the liftgate platform and other moving liftgate
parts, are clear before, and at all times during, operation of the liftgate. Do NOT allow
anyone to stand around the platform where a falling load could land on them.
16. Load and unload the platform from the rear and not from the side of the platform.
17. Never operate lift trucks on or over any part of the platform.
18. Follow all sections in this manual with “Maintenance” in the title – refer to “Table of
Contents” on Page 2.
(Warnings continued on following pages)

6.
19. NEVER move vehicle unless platform is properly stowed and power is off. Locking
cable curbside pin must have cotter pin installed before transit. An open liftgate on a
movingvehicleposesaserioustrachazard.
20. ALWAYS stow liftgate in transit position when not in use. Liftgates left in their open
positions, may create hazards for people and vehicles passing nearby.
21. Take care to retain cargo during transit. Liftgates are not designed to retain objects on
thetruck.Improperlyretainedobjects may fall fromthe vehicle and pose serious trac
hazards and larger objects could shift and damage the liftgate or truck
22. Any time the vehicle is washed, this liftgate MUST be inspected to MAKE SURE all
parts are properly lubricated and have the appropriate protectants. Failure to replace
lubricants and protectants after washing the vehicle, may lead to improper operation of
the liftgate, accelerated corrosion, and possible component failure.

An improperly positioned load can overload the liftgate and result in sudden liftgate failure and/
or increased risks to personnel of being hit or crushed by loads. IMPROPERLY POSITIONED
LOADS MAY RESULT IN SERIOUS PERSONAL INJURY AND/OR DEATH. Always position
loads properly on the liftgate platform. Follow information below on how to position loads
properly.
POSITION LOADS PROPERLY ON PLATFORM
 NEVERo-centertheloadontheplatform,fromside to side or away fromtruck as this
may overload the liftgate. The center of weight of the load should NEVER be placed beyond
the center of the platform load surface, away from truck. Loads should be placed close to the
platform edge nearest truck. If a load is not uniformly distributed, then the heaviest portion
should be closest to the edge of the platform nearest the truck. NEVER allow any part of the
loadtoextendbeyondtheedgesoftheplatform’satloadsurface.NEVERallowanypartof
the load to extend over or on, the tapered ramp portion of the platform unless the platform is
lowered completely to the ground and the ramp is supported by the ground.
!WARNING
FIG. 1
DO NOT OVERHEAT THE HYDRAULIC PUMP
Exceeding the duty cycle of the hydraulic pump, can overheat many components,
including the gear pump, the hydraulic motor, the motor start solenoid, valve coils, etc., and
signicantlyshortentheexpectedlifeofthesecomponents.Inextremecases,immediate
damage to the pump or related components may occur. Refer to the Thermal data below.
THERMAL DATA: To avoid overheating the motor do not operate this unit for more than 5
cycles/ 10 minutes with the maximum load. The motor then must be allowed to completely
cool down to ambient temperature before cycling the lift again. This unit also has a 10% duty
cycle, which means the liftgate can be cycled no more than 2 cycles/10 minutes constantly
with the maximum load.
