JIMMY SERIES HYDRAULIC REBAR BENDERS — SILICOSIS WARNING
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

JIMMY SERIES HYDRAULIC REBAR BENDERS — RULES FOR SAFE OPERATION
UNIT SAFETY INSTRUCTIONS
■
All hose connections must be tightened with the proper
tools before operating hydraulic power unit. DO NOT over
tighten. Connections should only be tightened securely
and leak-free. Over tightening can cause premature thread
failure or high-pressure fittings to split at pressures lower
than their rated capacities.
■
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 could cause serious injury.
■
NEVER subject the hose to potential hazard such as
fire, sharp surfaces, 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.
■
NEVER use the hose to move attached equipment. Stress
can damage the hose and possibly cause personal injury.
■
Hose material and coupler seals must be compatible with
the hydraulic fluid used. Hoses also must not come in
contact with corrosive materials such as creosoteimpregnated objects and some paints. Hose deterioration
due to corrosive materials can result in personal injury.
Consult the manufacturer before painting a hose. NEVER
paint a coupler.
■
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 cylinders.
Excess pressure can result in personal injury.
■
Inspect each cylinder and coupler before each shift or
usage to prevent unsafe conditions from developing.
■
DO NOT use cylinders if they are damaged, altered or in
poor condition.
■
DO NOT use cylinders with bent or damaged couplers or
damaged port threads.
■
DANGER - High Pressure Hazard
When extending a cylinder or ram
under load, always insure that the
couplers or port threads have not
been damaged or do not come in
contact with any rigid obstruction.
If this condition does occur, the
coupler’s attaching threads may
become stripped or pulled from the cylinder or ram
resulting in the instantaneous release of high pressure
hydraulic fluid, flying objects, and loss of the load. All of
these possible results could cause serious injury or even
death.
CAUTION - System Evaluation
Cylinder hoses, couplings and hydraulic pump must all be
rated for the same operating pressure, correctly connected
and compatible with the hydraulic fluid used. An improperly
matched system could cause the system to fail and
possibly cause serious injury. Always maintain the correct
operating for optimal performance. If you have any
questions, please contact your nearest MQ service center.
Avoid pinch points or crush points that can be created
by the load or parts of the cylinder. Do not wear loose
jewelry when operating the rebar bender.
WARNING
Moving parts can
crush and cut.
ALWAYS
clear of rollers while

When connecting the hydraulic power unit to a power
receptacle, make sure the receptacle circuit is connected
to either a GFCI receptacle or a receptacle protected by
a 20 amp circuit breaker.
■
When plugging the hydraulic power unit into a power
receptacle, check the nameplate for the correct operating
voltage. Operating the rebar bender at the wrong voltage
will damage the electrical components. ALWAYS read
the nameplate before applying power.
■
This hydraulic power unit is equipped with a 3-prong male
power plug. DO NOT use a 2-prong adapter when plugging
into a wall outlet. This will defeat the purpose of the ground
circuit. If the plug does not fit into the receptacle, contact
a qualified electrician to install a 3-conductor wall
receptacle (outlet).
■
Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased
risk of electrical shock if your body is grounded.

Electric-Hydraulic Pump
All Jimmy Series Hydraulic Rebar Benders require an electricpowered hydraulic pump to supply the necessary pressure to actuate
the hydraulic cylinder. This hydraulic pump consists of a drive
cylinder, oil reservoir and electronics for either remote or manual
operation.
The electric motor for this pump is a 1.5 HP motor. Each electric
motor requires 115 VAC, 60 Hz input for normal operation. Amperage
draw for the electric motor at 10,0000 psi (68,951 kpa) is
approximately 13 amps. Reference Figure 5 for oil volume versus
pressure.
The hydraulic pump is equipped with a 3-way, 3- position manual
operated valve. This valve allows the operator to remotely control
the
(4.57 meters) remote control cable allows the operator to control the
pump remotely.
