• Read, understand, and follow all instructions provided with
and on this device before use.
• All WARNING statements must be carefully observed to
help prevent personal injury.
• No alteration shall be made to this device.
• Always wear protective gear when operating
hydraulic equipment. Tie up long hair, wear
eye and ear protection, and non slip foot
wear.
• Keep hydraulic equipment away from flames
and heat. Hydraulic fluid can ignite and burn.
Do not operate if leaks are detected.
• Crush Hazard. Keep hands and feet away
from loading area. Avoid pinch points or
crush points that can be created by the load,
cylinder, or system components.
• To avoid crushing and related injuries:
NEVER work on, under or around a lifted
load before it is supported by appropriate
mechanical means. Never rely on hydraulic
pressure alone to support load.
HYDRAULIC PUMPS
•
The user must be a qualified operator familiar with the
correct operation, maintenance, and use of pumps. Lack
of knowledge in any of these areas can lead to personal
injury.
• Do not exceed rated capacity of the pump or any equipment
in the system.
• Never attempt to lift a load weighing more than the capacity
of the output device (cylinder, spreader etc.)
• Do not subject pump and its components to shock loads.
• Burst hazard exists if hose or connection pressure exceeds
rated pressure.
• Inspect pump, cylinder, hoses and connections before each
use to prevent unsafe conditions from developing. Do not
use if they are damaged, altered or in poor condition. Do
not operate the system with bent or damaged coupler or
damaged threads.
• Never hold or stand directly in line with any hydraulic
connections while pressurizing.
• ALWAYS use gauge or other load measuring instrument to
verify load.
• Never attempt to disconnect hydraulic connections
under pressure. Release all line pressure before
disconnecting hoses.
• Use of incorrect power source will damage the motor.
• Do not use an ungrounded (two-prong) extension cord.
• Do not install, remove or rewire the motor with power
applied. Have qualified technician to install, adjust and
service the motor.
!
WARNING
• Do not operate this device in an extreme temperature,
explosive atmosphere or in the presence of conductive
liquids.
• Always inspect hoses and connections for damage prior
to use.
• Ensure the device is placed on a hard, level surface.
• Ensure that application is stable to work on and around.
• Use only approved accessories and approved hydraulic
fluid.
• Never attach ANY component not authorized by
manufacturer.
• Do not connect to application which can return more oil to
the reservoir than the pump reservoir can hold.
• Do not connect pump to hydraulic system powered by
another pump.
• This device is not suitable for use as support device! As
the system load is lifted, use blocking and cribbing to
guard against a falling load.
• All personnel must be clear before lowering load or
depressurizing the system.
• Never try to disassemble a hydraulic pump, refer repairs
to qualified, authorized personnel.
HYDRAULIC HOSES & FLUID TRANSMISSION LINES
• Avoid short runs of straight line tubing. Straight line runs
do not provide for expansion and contraction due to
pressure and/or temperature changes.
• Reduce stress in tube lines. Long tubing runs should
be supported by brackets or clips. Before operating
the pump, tighten all hose connections with proper
tools. Do not overtighten. Connections should only be
tightened securely and leak-free. Overtightening can
cause premature thread failure or high pressure fittings
to burst.
• Should a hydraulic hose ever rupture, burst or need to
be disconnected, immediately shut off the pump and
release all pressure. Never attempt to grasp a leaking
pressurized hose with your hands. The force of escaping
hydraulic fluid can inflict injury.
• Do not subject the hose to potential hazard such as fire,
sharp objects, extreme heat or cold, or heavy impact.
• Do not allow the hose to kink, twist, curl, crush, cut or bend
so tightly that the fluid flow within the hose is blocked or
reduced. Periodically inspect the hose for wear.
• Do not pull, position or move setup by the hose.
• Hose material and coupler seals must be compatible with
hydraulic fluid used. Hoses also must not come in contact
with corrosive materials such as battery acid, creosote-
impregnated objects and wet paint. Never paint a coupler
or hose.
• FAILURE TO HEED THESE WARNINGS MAY RESULT
IN PERSONAL INJURY AS WELL AS PROPERTY
DAMAGE.
