WORDS OF CAUTION
1. Before any maintenance is performed on this unit, read and understand this
manual completely.
2. Do not stand on or behind the platform when operating gate in the folded
position.
3. Make sure the ground is clear under the platform when lowering.
4. Do not stand in front of platform when lowering from vertical position or operating
in any manner.
5. Never exceed the rated load capacity of this gate.
6. Do not allow persons to operate the unit unless they have been properly trained
to do so.
7. Use only factory authorized parts for replacement.
8. Check the area around the unit for persons before operating the lift gate.
9. This lift gate should operate smoothly and the only noise that should be heard is
the power unit. Any audible sounds other than the normal power unit operation
sound should be thoroughly inspected and the cause of the noise should be pin-
pointed and corrected.
10.Do not over load – the maximum rated capacity is based on an evenly distributed
load all over the platforms flat surface.
11.Always load as close to the center of the platform and as close to the center of
the truck sill as possible.
12.150 Amp circuit breaker (not supplied) must be installed between the starter
solenoid and the battery source.
Order from factory as option #111-Circuit Breaker.
We urge the installation of a safety cut-off switch for all truck mounted lift gates. These
are installed in the cab of the vehicle, so the power to the lift gate can be turned on/off.
WARNING: Since this gate has greaseless bearings in the main pivot points,
(tension and compression arms and platform parts) any welding on these parts must
be grounded or you will damage the cylinder.
WARNING: Pressure relief valve in power unit must NEVER be set above
2500 psi. Pressures above 2500 psi can damage lifting arms. Failure to follow this
warning could result in accident or injury.

OPERATING OF THE LIFT GATE
Before operating the lift, read and understand this decal, urgent warning decal,
and the Owner’s Manual.
Do not stand behind the lift gate while unfolding or using the platform.

Step 1: TRUCK-PREP BEFORE MOUNTING GATE
1. Carefully check dimensions given on page 5. Verify you have the proper space
available to mount the gate. 24-1/2” represents the standard mounting height.
For a bed height of 44”, this mounting height will yield 10” ground clearance
(unladen).
2. If more ground clearance is required, or the bed height is less than 44”, the 24-
1/2” mounting dimension can be reduced. For every 1” reduction in the 24-1/2”
dimension, you will need approximately one additional inch in clearance between
the door sill and truck chassis (beyond the 28” minimum dimension). Example: if
the mounting dimension is reduced to 22-1/2”, you will need approximately 30”
between the door sill and the truck chassis.
3. Once it is clear, the proper space is available for gate installation, the door sill
must be notched per dimensions on page 7. It is important the sill be reinforced
after notching using gussets as described on page 7. The sill must be strong
since it serves as the “up” stop for the gate.
Step 2: MOUNTING GATE TO TRUCK (SIDE DOOR)
1. Unfold the secondary platform.
2. Clamp the secondary platform to the lift truck approximately centered (see
illustration on page 8).
3. There are two angles in the shipping kit (5 x 3 x 1/4 x 3 lg.). Lay these two
angles on top of the door sill to space the platform out 1/4” (see sketch on page
8).
4. Pick up the gate assembly. Position it at the door opening as required and push
it against the sill and the 1/4” spacers. With two pieces of scrap channels or
angles, clamp platform flush with floor. Use four clamps. Clamp channels to sill
and platform. Flat area of platform farthest away from truck should be 1” higher
than door sill to allow for platform deflection under load. Step 16 on page 11,
explains how to use the shims provided to adjust platform slope.
5. With a floor jack and piece of 4 x 4 wood, swing and raise the main tube until it is
at the 24-1/2” standard dimension – or a reduced dimension if needed. With a
pipe wrench rotate the main 4 x 6 trunion tube, so it is vertical. You should see
approximately 3/8” of exposed rod on the cylinder if you used the standard 24-
1/2” mounting height.

6. Now locate all the component parts, which make up the TSG mounting plate
assembly, reference page 9 to identify them. The centerline of the two mounting
plates should be spaced at least 30” apart. Hold parts up to locate holes
required in truck chassis and mark gussets and plates for trimming.
7. Lower floor jack and let gate swing out of the way. Drill 9/16” holes through
chassis to attach both mounting plates. Bolt plates in place using hardware
supplied. Lift trunion tube of gate back in position.
8. Now tack weld the gussets and support plate to the mounting plate and trunion
tube. Welds must be strong enough to support the gate without a load on the
platform.
9. Locate a suitable spot to mount the power unit enclosure. Use the two brackets
and shims supplied. Refer to the sketch on page 10. Connect the hydraulic
hose and plastic tubing from the lift cylinder to the power unit.
10.Unclamp the four clamps holding the back of the platform next to the door sill.
Caution: Do not unclamp the tip of the platform.
11.Let the lift truck forks down slowly until they will not go any further. They will stop
about half way down when they meet resistance from the oil in the lift cylinder.
