! WARNING
• Avoid pinch points or crush points that can be
created by the load or parts of ram.
• To help prevent material fatigue if the ram is to be
used in a continuous application, the load should
not exceed 85% of the rated capacity.
• Ram must be on a stable base which is able
to support the load while pushing or lifting.
• Ensure ram is fully engaged into/onto adapters,
extension accessories.
• To help prevent personal injury, use shims,
friction material or constraints to prevent
slippage of the base or load.
• Do not off-center loads on a ram.
The load can tip or the ram can
“kick out” and cause personal
injury.
Center loads on ram
• As the load is lifted, use blocking and cribbing to
guard against a falling load.
• Never allow personnel to work on, under or
around a load before it is properly supported by
appropriate mechanical means. Never rely on
hydraulic pressure alone to support load.
• All personnel must be clear before lowering.
• Never try to disassemble a hydraulic cylinder,
Refer repairs to qualied, authorized personnel.
IMPORTANT
• Keep ram clean at all times.
• When the ram is not is use, keep the piston(s)
fully retracted.
• Use an approved, high-grade pipe thread sealant
to seal all hydraulic connections. Teon tape can
be used if only one layer of tape is used and it is
applied carefully (two threads back) to prevent the
tape from being introduced into hydraulic system.
A piece of tape could travel through the system
and obstruct the ow of uid and adversely affect
function.
• Never attach ANY component not authorized by
manufacturer.
• Never use other than factory provided and/or
authorized fasteners.
KNOW YOUR SYSTEM
Your ram, hose(s), couplings and pump all must be
rated for the same maximum operating pressure,
correctly connected and compatible with the hydraulic
uid used. An improperly matched system can cause
the system to fail and possibly cause serious injury.
If you are in doubt, consult your nearest Atd Tools
Dealer.
! WARNING
Hydraulic Hoses and 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, all hose connections must
be tightened with the proper tools. Do not
overtighten. Connections should only be tightened
securely and leak-free. Overtightening can cause
premature thread failure or high pressure ttings
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 uid can
inict injury.
• Do not subject the hose to potential hazard such
as re, 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 uid ow within
the hose is blocked or reduced. Periodically
inspect the hose for wear, because any of these
conditions can damage the hose and possibly
result in personal injury.
• Do not pull, position or move setup by the hose.
Doing so can damage the hose and possibly
cause personal injury.
• Hose material and coupler seals must be
compatible with hydraulic uid used. Hoses also
must not come in contact with corrosive materials
such as battery acid, creosote-impregnated
objects and wet paint. Hose deterioration due to
corrosive material can result in personal injury.
Never paint a coupler or hose.
• The user must be a qualied operator familiar
with the correct operation, maintenance, and use
of rams. Lack of knowledge in any of these areas
can lead to personal injury.
• Use only approved accessories and approved
hydraulic uid.
• Do not exceed the rated capacity of the ram.
• Inspect each ram and coupler before each use to
prevent unsafe conditions from developing.
• Do not use rams if they are damaged, altered or
in poor condition.
• Do not use rams with bent or damaged coupler or
damaged threads.
• Under certain conditions, the use of an extension
with a hydraulic ram may not be advisable and
could present a dangerous condition.
