3 Important Information
Before Getting Started
“READ FIRST”
The ILF liftgate is a heavy duty industrial hydraulic lifting device. Performance and reliability
are closely related to proper installation, battery cable connections, and grounding. All
grounding surfaces MUST be cleaned, prepped, and sealed per this manual. “Cut to size”
cables MUST be properly crimped and sealed as factory supplied. All connections MUST be
dressed with dielectric grease or equivalent sealer.
Review lift gate invoice, packing slip, and installation drawing to assure delivery of correct gate
and complete delivery of accessories and optional equipment.
Read and understand the “Installation Manual” and “Owner’s Manual” in their entirety before
starting your Installation.
Refer to your truck manufacturer’s instructions before adding any auxiliary equipment. Installer is
responsible for compliance with this manual, OEM and FMVSS requirements.
All welding should be performed by qualified personnel per AWS standards.
Always Ground closest to your welding point to prevent arcing through moving parts or electrical
parts.
Contact PALFINGER Liftgates for Special Installations not covered in this Installation Manual.
Do not paint cylinder shafts or nylon bearings (Use non-chlorinated brake cleaner to remove over
spray)
Final Check-Off-Sheet at rear of this manual MUST be filled out and kept in your records for
future reference.
Refer to owner’s manual for Operation and Maintenance information.
Check the battery voltage before installation. Flooded lead acid batteries should measure 12.6V
and AGM batteries should measure 12.8V. If batteries are not at these voltages, fully charge
before installation

Important Dimensions 3.1
Minimum Bed Height dimensions are ALWAYS MAXIMUM LOADED TRUCK.
Maximum Bed Height dimensions are ALWAYS DRY UNLOADED TRUCK.
Installing a gate at or close to minimum bed height normally results in a gate that will NOT open
and close from stored position if the minimum floor height is exceeded when truck is loaded.
Ensure trailer body does not interfere with installation or operation of the ILF liftgate series.
It is not recommended to cut, torch, or remove support materials from trailer. Removing gussets,
stiffeners, light rings, or other such support structures may VOID your trailer warranty.
Call technical support before starting the installation if any questions or concerns arise on
mounting dimensions or procedures.
Mounting Notes:
Read and clearly understand manual BEFORE beginning ANY work.
The basic rule of PALFINGER Liftgates‟s ILF installation is to lift mount frame
to achieve MAXIMUM ground clearance WITHOUT exceeding Min “F” dimension.

7 Liftgate Installation (Truck)
Warning: Never work or place yourself under unsupported platform
High heat and spatter from welding can damage components. Make sure
components such as hoses, lines, and wires are clear of or protected from heat and spatter caused
by welding.
Prior to beginning installation, assure the vehicle is on a leveled surface.
NOTE: The installation process for an ILF 33, ILF 44, and ILF 55 is the same for all gates. For
illustration purposes, an ILF 44 is shown.
Protect all wires and cable from dropping slag or splatter when welding mount plates.
Make sure to have power pack pulled out when welding the tube and hoses and cables
are away from walls..
Do no apply a load to the platform at anytime during installation.

Operation of B-15 Sensor 8.2
The B-15 Sensor allows the platform to tilt, up or down, once it has reached a minimum height off the
ground, Fig. 19. The sensor will not allow the platform to tilt after a certain height off the ground for safety
purposes. The titling function allows the platform to tilt down as close as possible to the ground for easy
loading and unloading of cargo.
To adjust the B-15 sensor, if necessary:
1. Loosen (2) 5mmx50mm Allen Head sensor mount screws and rotate slightly for re-adjustment.
Fasten screws after adjustment is complete.

Never exceed rating of existing fuses located at the battery, control board and/or the pump and
motor which may result in serious damage to the equipment.
Never jump the 150 Amp circuit breaker at the batteries unless otherwise instructed by the
PALFINGER Liftgates technical support team.
All connections should be heat shirk protected and all open ended terminals must be
replaced with closed end terminals or the open ends must be protected with heat shrink
tubing.
Never secure a cable in a way where it can make contact with other wiring, brake-, fuel- or air-
lines, or get pinched against other objects.
It is highly recommended to use 2 gauge wire throughout the electrical system when
connecting to batteries.
Do not splice battery cables unless otherwise instructed by the Palfinger LIftgates technical
support team.
