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.
• For good performance, do not expose
equipment to high temperature.
Extreme heat may damage hose
materials, packing and sealing.
• The user must be a qualified operator
familiar with the correct operation,
maintenance, and use of rams. Lack
of knowledge in any of these areas
can lead to personal injury.
• Read and understand all safety and
warning decals and instructions.
• Use only approved accessories and
approved hydraulic fluid. Hoses,
seals and all components used in a
system must be compatible with the
hydraulic fluid used.
• Do not exceed the rated capacities of
the rams. Excess pressure can result
in personal injury.
• 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 ram may not
be advisable and could present a
dangerous condition.
• 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.
• Do not use the locking collar on
threaded piston as a stop. The threads
may shear resulting in loss of the load.
• If this component is used to lift or lower
loads, be certain that the load is under
operator control at all times and that
others are clear of the load. Do not
drop the load.
• 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 qualified,
authorized personnel.
IMPORTANT
• Keep ram clean at all times.
• When the ram is not in use, keep the
ram(s) fully retracted.
• Use an approved, high-grade pipe
thread sealant to seal all hydraulic
connections. Teflon 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 flow of fluid 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 fluid
used. An improperly matched system
can cause the system to fail and possibly
cause serious injury. If you are in doubt,
consult your nearest Snap-on Dealer.

and safety goggles to

All WARNING
statements must be
carefully observed to help prevent
personal injury. Do not exceed rated
capacity. Monitor pressure and load
at all times. Always verify load with
calibrated load cell and indicator,
known good pressure gauge or
equivalent devices. Wear appropriate
shoes. Do not wear sandals when
operating this equipment. Do not
wear jewelry when operating this
equipment.
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 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, 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.
