!Caution:
Never leave the truck with the platform on the ground, partially raised, or open.
Never show children or unauthorized personnel how to operate the gate.
To prevent children or unauthorized personnel from operating the lift, be sure the gate is in the stored
position and both the driver's side and passenger's side latches are secured. Make sure the passenger's
side latch padlock is installed and the control is deactivated before leaving the truck unattended.
!Warning: The Tommy Gate is an industrial product for material handling only and is not to
be used as a personnel or wheelchair lift. Do not ride on the platform and always
stand clear of the platform when opening, raising or lowering.
Your Tommy Gate is connected to your vehicle battery. The vehicle battery powers a motor, coupled to a
hydraulic pump. This motor and pump combination is called a power unit. Flow from the pump retracts the
two cylinders attached to the upper arm assembly that lift the gate platform.
!Warning: Liftgate is not to be used as a scale. Liftgate may lift more than its rated capacity.
Be aware of how much is being lifted and never exceed the rated capacity of the
liftgate. Be aware of how much is being hauled and never exceed the rated
capacity of the vehicle.
The gate platform is lowered by gravity after an electric "lower" solenoid valve is activated and opened at the
power unit.
Tommy Gate's control incorporates a "Low Voltage" warning feature. A "Low Voltage" condition exists
when the "Power On" button is armed and 7 Volts or less is present at the power unit. This "Low Voltage"
feature is designed to warn the operator that there is a low voltage condition and that it should be corrected as
soon as possible. The amber "Power On" LED will blink to warn the operator of this condition. When this
light is blinking, it will not prevent the control from functioning to raise or lower the gate. In a "Low Voltage"
situation, whether the gate actually raises or lowers depends on how low the voltage is.
Caution:
Continuing to operate the the liftgate in the "Low Voltage" condition may result in failure of electrical
components in the power unit.
The low voltage condition may be caused by a weak battery, loose or corroded connections, improper ground,
or bad electrical cables. This condition may be corrected by just starting the vehicle or replacing the battery.

OPERATOR'S INSTRUCTIONS
Step 1. To open the platform, go to the driver's side of the Tommy Gate,
push the latch to the side, off the platform pin, and rotate the
latch down. Proceed to the passenger's side of the Tommy Gate
and remove the latch padlock. Push the passenger's side latch to
the side, off the platform pin with one hand while holding
the top of the platform with your other hand. Pull the platform
open and step away from the platform as it opens.
Lift-N-Dump Models only (Figures 2 - 3)
!Caution:
Never use Lift-N-Dump as a liftgate when the dump body hoist is raised.
Hold down clamps must be used to secure dump body to truck frame when
a single action body hoist is used.
Never unfold the platform, unless both insert latch pins are fully engaged
in the platform frame, and the latch lever is latched and pinned.
To open the Lift-N-Dump platform, open the hasps
and remove the driver side lynch pin. Remove the
padlock on passenger side.
Step 2. If the gate is on an application with swing out doors,
you can open them at this time.
Step 3. Be sure to stand clear of the platform and all moving
parts when using the lift.

Step 4. To turn the control power on, press the "POWER ON" hidden
switch once, marked with white rings or circles (located between the
Tommy Gate logo and the toggle switch). You should see the amber
LED "POWER ON" light when the control is armed. To disarm the
control press the "POWER ON" hidden switch again. To activate the
control, press the "LIFTGATE ACTIVATED" hidden switch twice within
one second (located under the Tommy Gate logo). You should see the red
"LIFTGATE ACTIVATED" light when the control is activated. To lower
the platform, push the toggle switch down. To raise the platform, push the toggle
switch up. When you remove pressure from the toggle switch, the operation will
stop. After you have activated the control by pressing the "LIFTGATE
ACTIVATED" hidden switch twice within one second
(located under the Tommy Gate logo), you have
approximately 90 seconds to use the gate. If the gate is
not used for approximately 90 seconds, the "LIFTGATE
ACTIVATED" timer deactivates the control. If the gate is
used during the 90 seconds, the "LIFTGATE
ACTIVATED" timer automatically resets for an additional
90 seconds. To reactivate the timer, press the "LIFTGATE
ACTIVATED" hidden button twice within one second.
Step 5. After the platform is raised to the level of the vehicle's
floor and the load is removed, close the platform and folding
extension (if so equipped). The latch on the passenger's side
will secure itself. Install the latch padlock on the passenger's
side latch. Go to the driver's side and secure the latch.
DPN: 009120 Page 8 of 28 Rev 29 11-2-23

Center the platform latch pin vertically in the latch hole. Push the platform latch pin
toward the front of the truck so there is a 1/8" gap (Page 10, Figures 10 & 11) .
Tighten the platform latch pin with a 9/16" wrench and a screwdriver.
Check the spring tension on the driver's side and passenger's side latch springs as
shown (Page 10, Figures 8 & 9). The driver's side swing away latch spring should
measure 1" tall. Tighten or loosen if necessary. The passenger's side fixed latch
spring should measure 7/8" tall. Tighten or loosen if necessary.
Loosen the platform latch pin with a 9/16"
wrench and a screwdriver. The hole in
the platform is oversized to allow
the platform latch pin to be adjusted.
See exploded view drawing (Figure 7).
Close and latch the platform.

As is with any mechanical product, a preventive maintenance program needs to be followed in order
to keep it in its best operating condition. Please review this information and if you should have any
questions, please call [phone]. Please have your model number and serial number available.
The Tommy Gate needs to be serviced every 120 days or 1500-2000 cycles, whichever comes first.
(A) Inspect platform chains for any wear. Replace immediately if either is found to be worn.
(B) Check the oil level in the reservoir. With the liftgate platform at the bottom of its travel,

EXTENDED.
(C) Check for leaks from the cylinders, hoses, and all fittings (replace or repair if found to be
leaking).
(D) Grease all cylinder pivots with an ample amount of grease (every 120 days).
Do not grease composite bushings.
(E) Replace any worn or missing parts before the liftgate is put back into service.
(F) If needed, adjust platform latches which are designed to hold
the liftgate in a properly stored position.
(G) Check for cracks in all welds (repair if needed).
(H) Check for wear at all pivot points.
(I) Check all electrical connections.
