SAFETY PRECAUTIONS
Installing or operating this hoist without rst understanding proper installation and opera-
tion procedures could lead to serious injury or death. Always read and fully understand
all installation and operation manuals before installing or operating this equipment. Con-
tact Primary Mover with any questions.
WARNING!
Overloading a trailer could cause vehicle or trailer component damage
resulting in injury or death. NEVER exceed the gross vehicle weight (GVW) or gross
axle weight (GAW) rating of the trailer or your vehicle.
WARNING!
Damage to brake lines during manufacturing and installation of the hoist,
as well as installing any hardware (bolts, nuts, brackets) in a way that they may rub
and damage the brake system, could lead to brake failure. This can cause an accident
that could cause injury or death. ALWAYS take adequate steps to prevent brake sys-
tem damage during installation of the hoist, and take precaution to ensure that installed
equipment does not interfere with brake system.
WARNING
!
Malfunctioning equipment could cause property damage, injury or death.
ALWAYS have faulty equipment repaired before continuing use. Consult the trailer
manufacturer if required.
WARNING!
Welding, oxy-fuel cutting, or grinding could cause fuel to ignite. This
could lead to injury or death. ALWAYS take adequate steps to avoid the ignition of fuel
from fuel tanks when welding, oxy-fuel cutting, and/or grinding during installation.
Heat from the vehicles exhaust system could cause hydraulic component failure. This
could lead to a re that can lead to injury or death. ALWAYS install equipment in loca-
tions where the exhaust system heat will not damage any components critical to opera-
tion.
WARNING
!
Never attempt to jerk or shock the trailer body with the body raised to
remove a stuck load. Jerking or shocking the trailer in this position can cause dam-
age that could result in injury or even death. NEVER drive forward or reward and stop
quickly to “un-stick” the load. If load is stuck, lower trailer body and free load.

SAFETY ARM INSTALLATION AND USE
Always support an unloaded body with the safety arm. The safety arm
is meant to support the weight of an unloaded body only.
DANGER
!
Being under a raised body could result in serious injury or death should
the body unexpectedly descend. Never position yourself or allow others to position
themselves under a loaded body. Always support an unloaded body with the supplied
safety arm. NEVER use the safety arm on a loaded body.
Safety Arm Use:
1. Raise trailer body to su󰀩cient height and shut o󰀨 hydraulic power to hoist.
2. Grasp safety arm and rotate into the up/vertical position.
3. Once vertical position is accomplished, push arm down into the support bracket at
base of arm.
4. SLOWLY lower the hoist and body until the cup contacts the vertical facing arm.
5. Reverse the above procedure to place arm back in its hanger for transport (be sure
to lower hoist to full down position upon placing arm back in hanger).

SINGLE AND DUAL ACTING HYD. POWER UNIT INSTALLATION
If included with the kit, mount HPU (hydraulic power unit) in a weather tight enclosure
on the trailer. See additional instructions supplied with the HPU for mounting, electrical,
wireless remote and hydraulic uid requirements.
!CAUTION
Hydraulic components that are not provided by Primary Mover and
WARNING
!
Adjusting the hydraulic pressure to exceed the recommended
limits or setting could cause the jack to fail during operation. Such failure could cause
property damage, personal injury, or death. Pressure should ONLY be adjusted by a
trained and qualied technician or mechanic, and should never exceed stated limits or
settings of components used.
Hydraulic System Pre-Operation
The hydraulic system supplied by Primary Mover consists of components (pump,
valves, reservoir, hoses, cylinder, etc.) that are designed to be compatible with each
other.
All Primary Mover’s liability and warranty will be voided if determined by Primary
Mover that substituted hydraulic components (i.e., hydraulic components not provided
by Primary Mover as part of the kit) were used and such components were
incompatible with components of the kit provided by Primary Mover. Hydraulic
parameters are shown below. These are listed as a general
guide to ensure proper compatibility (when using other hydraulic components). If you
have any questions about component compatibility, please contact Primary Mover
before installation, use or maintenance.
Maximum Working Pressure---3200 PSI
Hydraulic Port Type--#6 JIC
are used in the hydraulic circuit that are incompatible with Primary Mover components
may cause damage to, or failure or malfunction of, the direct push cylinder or other
components of the Primary Mover product(s). Such damage, failure or malfunction may
cause property damage, personal injury or even death, It is the purchaser’s
responsibility to verify the compatibility of components not provided by Primary Mover.
! W ARNING
Connecting the jack to a hydraulic system with more
pressure (PSI) or flow (GPM) than is recommended by Primary Mover could cause the
jack to fail during operation. Such failure could cause property damage, personal injury,
or even death. Ensure that you have pressure that does not exceed tolerances and
limits stated for your Primary Mover product(s)/component(s), and that there is no
restriction or issue concerning flow before operation. Consult Primary Mover if you are
unsure about the limits, capacities and/or tolerances of your hydraulic system.

TYPICAL BATTERY HOOKUP
WARNING
!
Shorting of the electrical system brought about by installation, servicing
or repairing battery related connection and electrical components can cause sparks,
ignition of combustible material and/or re which in turn can lead to property damage,
personal injury or death. ALWAYS disconnect the battery prior to installing, servicing, or
repairing power unit.
Mount battery in a weather tight enclosure on the trailer. See additional instructions sup-
plied with the HPU for mounting, electrical and hydraulic uid requirements.
