Section 2: Safety and Warnings
Warning
Read all instrucons thoroughly before installaon or use of this li. Failure to following the instrucons in this manual
and the associated manuals for tesng and operaon could result in serious injury or death. In addion, it will render
RAM’s warranty null and void.
Read all instrucons thoroughly before installaon or use of this li. Failure to following the instrucons in this manual
and the associated manuals for tesng and operaon could result in serious injury or death. In addion, it will render
RAM’s warranty null and void.
The li is intended for use by people and not to be used for cargo or other purposes. Liing capacity is up to a
maximum of 750 lb. unless otherwise noted on the li and in RAM’s supplied documentaon. (DO NOT OVERLOAD
THE LIFT). Overloading the li will render RAM’s warranty null and void.
RAM Manufacturing Ltd. (RAM) disclaims any and all liability for any personal injury or property damage resulng from
the operaon of a product that has been modified from the original design. No person or company is authorized to
change the design of the product without wrien authorizaon by RAM
Do not override any of the safety devices provided with the li. Doing so will likely lead to serious injury or even death.
Ensure there is a minimum of 2in (50mm) and a maximum of 3in (75mm) clearance between any part or edge of the
carriage that could possibly be used as a supporng handhold and any part of the fixed installaon to prevent the
trapping of a hand during the travel of the carriage. See RAM installaon drawings for details.
Ensure that there is nothing obstrucng the carriage travel before operang the li.
Failure to observe and complete the required maintenance for your liproduct will render the warranty
null and void and may present significant risk that could lead to injury or death.
Do not work underneath the plaorm without fist securing the plaorm and/or using a shoring bar as well
as locking out the controls

Section 3: Maintenance Requirements
3.1 Monthly Inspection (by owner or technician):
3.1.1 Inspect all gates/doors and ensure they are locked when the lift is not
at the landing. Also check that the lift will not run unless the gates / doors
are fully closed and locked once the platform is more than 2” (50mm) from
the landing.
3.1.2 Inspect under pan safety device for correct operation
3.1.3 Verify E-Stop button is working
3.1.4 Inspect the toe plate and ensure it is operating smoothly and moving
into the up position when the lift leaves the lower landing. Also test that it
will resist load being applied to it (up to 125lb)
3.2 Annual Maintenance (by technician):
The Trus -T-Li™ should be inspected and maintained annually. The following is a
non-exhausve list items of that should be checked as part of an annual
maintenance in order to maintain safe operaon of your li. An inspecon and
maintenance is required to be completed by an authorized RAM dealer for any
extended warranty claims to be valid.
All the above monthly items + the following:
3.2.1 Inspect the drive nuts
Compare the amount of movement in the drive nuts from side to side and
up and down without rotang the drive nut at all. If they feel overly sloppy
or as though threads may be missing, then they need to be replaced. Signs
of bronze thread material or shavings are another indicator of worn liing
nuts. If the amount of movement is minimal spin the drive nuts by hand to
check for resistance, if any resistance is felt or the drive nut binds then they
must be replaced.

3.2.2 Inspect the drive screw
Inspect the drive screw for any irregularies, sharp edges or foreign
objects and dirt caught in the threads. Be sure no damage exists to the
drive screw and that it is enrely clean of debris. Replace screw if
damaged.
3.2.3 Clean and re-lubricate the drive screw
In order to lubricate the drive screw you must remove the main front panel
and a carriage guide frame panel. Use a clean rag to wipe all of the grease
offof the screw. Liberally apply Mobilith SHC-460PM grease on the drive
screw.
3.2.4 Inspect the drive belt
Remove the top cover and inspect the drive belt for wear. A small amount
of black rubber bits below the belt is normal. If there is any significant sign
of wear to the belt, replace.
3.2.5 Inspect for surface damage and complete touch ups to coatings
Wear and tear may occur on powder coated steel surfaces resulng in
scratches. Small points of damage can be wire brushed and touched up
with the small touch up paint containers that come with each liRAM
ships out. This will extend the life and cosmec look of you liand is
parcularly important in any environments that are coastal or potenally
corrosive.
3.2.6 Inspect cables
Tears in insulaon should be patched where possible and if bare wire is
present new replacement cables should be purchased and installed by a
qualified technician. Consult your RAM dealer for spare parts should they
be required.
3.2.7 Inspect for correct functioning of toe plate – if applicable
The toe plate actuaon mechanism may be crical to access and both the
mechanism and the toe plate itself should be examined. If there are any
concerns adjust the mechanism or repair/ replace it.
3.2.8 Re-check platform alignment and clearances
Buildings and construcon “seles” over me and adjustments may be
required to ensure good clearances and alignment of the li. Consult the
appropriate secons of the installaon manual or RAM’s technical support
team for guidance.

3.2.9 Inspect and Test All Interlocks and Safety Devices
Interlocks and all other safety devices should be tested to ensure they
work in the appropriate manner. If you are uncertain whether they are
operang correctly, please consult with your RAM dealer or call RAM’s
technical support team.
3.2.10 Complete testing outlined in section 4
Section 4: Testing Required
Once all the wiring connecons are confirmed, the mechanical assembly is complete and the li
is secured you can proceed with tesng to prove that all systems and main safety funcons are
acve and funconal.
4.1Weight Testing
Every lishould be weight tested once the installaon for mechanical and electrical items is
complete to ensure that the liis operang correctly. All lis are tested at the factory but they
are then disassembled and shipped to sites across North America.
The licapacity may vary but this will be noted on the liserial number label as well as other
documentaon.
Weight tesng may comprise 2 elements:
1. Maximum Liing capacity – you apply full load to the liin the center of the center of the
plaorm and the lishould operate in the upward direcon. Current draw by the machine
should be less than 13A.
2. Overload tesng – North American Safety code requires that with 125% the lidoes not
move in the downward direcon unintenonally. To test this, raise the liroughly 12 in
and apply 125% of rated working load and check that the lidoes not move in the
downward direcon unintenonally. The liis not required to li125% of working load.
