of length or configuration of the truck leveling
device and information identifying the maximum
uncontrolled drop encountered when sudden
removal of support while in the working range of the
equipment.
2) When selecting loading truck safety equipment, it is
important to consider not only present requirements
but also future plans and any possible adverse
conditions, environmental factors or usage. The
owners/users shall provide application information
to the manufacturer to receive recommendations on
appropriate equipment specifications and capacity.
3) The Owner/User must see all nameplates, placards,
decals, instructions and posted warnings are in
place and legible and shall not be obscured from
the view of the operator or maintenance personnel
for whom such warnings are intended for. Contact
manufacturer for any replacements.
4) Truck leveling devices may become hazardous
if the manufacturer’s instructions regarding
modifications or adjustments are not followed.
Modifications or alterations of truck leveling devices
shall only be made with prior written approval from
the original manufacturer. These changes shall
be in conformance with all applicable provisions
of the MH30.1 standard and shall also satisfy all
safety recommendations of the original equipment
manufacturer of the particular application.
5) The owner/user should recognize the inherent
dangers of the interface between the loading truck
and the transport vehicle. The owner/ user should,
therefore, train and instruct all operators in the safe
operation and use of the loading truck equipment in
accordance with manufacturer’s recommendations
and industry standards. Effective operator
training should also focus on the owner’s/user’s
company policies, operating conditions and the
manufacturer’s specific instructions provided with
the truck leveling device. Maintaining, updating and
retraining all operators on safe working habits and
operation of the equipment, regardless of previous
experience, should be done on a regular basis and
should include an understanding and familiarity with
all functions of the equipment. Owners/users shall
actively maintain, update and retrain all operators
on safe working habits and operations of the
equipment.
6) An operator training program should consist of, but
not necessarily be limited to, the following:
a) Select the operator carefully. Consider the
physical qualifications, job attitude and aptitude
b) Assure that the operator reads and fully
understands the complete manufacturer’s
owners/users manual.
c) Emphasize the impact of proper operation upon
the operator, other personnel, material being
handled, and equipment. Cite all rules and why
they are formulated.
d) Describe the basic fundamentals of the truck
leveling device and components design as
related to safety, e.g., mechanical limitation,
stability, functionality, ect.
e) Introduce the equipment. Show the control
locations and demonstrate its functions.
Explain how they work when used properly and
maintained as well as problems when they are
used improperly.
f) Assure that the operator understands the
capacity rating, nameplate data, placards and all
precautionary information appearing on the truck
leveling device.
g) Supervise operator practice of equipment.
h) Develop and administer written and practical
performance tests. Evaluate progress during and
at completion of the course.
i) Administer periodic refresher courses. These
may be condensed versions of the primary
course and include on-the-job operator
evaluation.
7) Loading truck safety equipment should never be
used outside of its vertical working range, or outside
the manufacturer’s rated capacity. It shall also be
compatible with the loading equipment and other
conditions related to truck activity. Please consult
the manufacturer if you have any questions as to
the use, vertical working range or capacity of the
equipment. Only properly trained and authorized
personnel should operate the equipment.
8) It is recommended that when the transportation
vehicle is positioned as close as practical to the
truck leveling device and in contact with both
bumpers, there shall be a minimum of 4.00 inches
(100mm) overlap between the front edge of the
lip and the edge of the floor or sill of the transport

The PowerLift truck leveler uses a dual push button
operation for ease of use.
The truck leveler is operated by:
1.) Depress RAISE button (F) on the control panel
to activate an electric motor which drives the hydraulic
pump. The hydraulic pump forces oil in the truck
levelers main platform cylinders(B), causing the unit to
raise to the desired height of the transport vehicle.
2) Depress the LOWER button(G) on the control
panel which activates a control solenoid that allows
the hydraulic oil to return to the reservoir and lower the
unit.
