avoided,mayresultinpropertydamage.
IMPORTANT:Importantisusedwhenactionorlackofactioncancauseequipmentfailure,eitherimmediate
oroveralongperiodoftime.
WARNING: To prevent personal injury,
• The following procedures must be performed by qualied, trained personnel who are familiar
with this equipment. Operators must read and understand all safety precautions and operating
instructions included with the pump. If the operator cannot read these instructions, operating
instructions and safety precautions must be read and discussed in the operator's native
language.
• These products are designed for general use in normal environments. These products are
not designed for lifting and moving people, agri-food machinery, certain types of mobile
machinery, or in special work environments such as: explosive, ammable, or corrosive.
Only the user can decide the suitability of this product in these conditions or extreme
environments. Hydraulic Technologies will supply information necessary to help make these
decisions. Consult your nearest Hydraulic Technologies facility.
• Safety glasses must be worn at all time by the operator and anyone within sight of the unit.
Additional personal protection equipment may include: face shield, goggles, gloves, apron,
hard hat, safety shoes, and hearing protection.
• The owner of this tool must ensure that safety-related decals are installed, maintained, and
replaced if they become hard to read.
• Shut OFF the motor before opening any connections in the system.
Pump
WARNING: To prevent personal injury,
• Do not exceed the hydraulic pressure rating noted on the pump nameplate or tamper with
the internal high pressure relief valve. Creating pressure beyond rated capacities can result
in personal injury.
• Retract the system before adding uid to prevent overlling the pump reservoir. An overll
can cause personal injury due to excess reservoir pressure created when tools are retracted.

Electric Motor
WARNING: To prevent personal injury,
• Electrical work must be performed and tested by a qualied electrician per local
directives and standards.
• Disconnect the pump from the power supply and relieve pressure before removing the
motor case cover or performing maintenance or repair.
• Check the total amperage draw for the electrical circuit you will be using. For example:
Do not connect a pump that may draw 25 amps to a 20 amp fused electrical circuit.
• Never use an ungrounded power supply with this unit.
• Changing the voltage is an involved and, if incorrectly performed, hazardous procedure.
Consult the manufacturer for specic information before attempting rewiring.
• Wire pump motors for counterclockwise rotation when viewed from the shaft end of
the motor.
• Do not attempt to increase the power line capacity by replacing a fuse with another
fuse of higher value. Overheating the power line may result in re.
• Exposing electric pumps to rain or water could result in an electrical hazard.
• Avoid conditions that can cause damage to the power cord, such as abrasion, crushing,
sharp cutting edges, or corrosive environment. Damage to the power cord can cause
an electrical hazard.
Hoses
WARNING: To prevent personal injury,
• Before operating the pump, tighten all hose connections using the correct tools. Do
not overtighten. Connections should be only secure and leak-free. Overtightening can
cause premature thread failure or high pressure ttings to split at pressures lower
than their rated capacities.
• Should a hydraulic hose rupture, burst, or need to be disconnected, immediately shut
off the pump and shift the control valve twice to release pressure. Never attempt to
grasp a leaking hose under pressure with your hands. The force of escaping hydraulic
uid could cause serious injury.
• Do not subject the hose to potential hazard, such as re, sharp surfaces, heavy impact,
or extreme heat or cold. Do not allow the hose to kink, twist, curl, 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 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 uid used.
Hoses also must not come in contact with corrosive material such as creosote-
impregnated objects and some paints. Consult the manufacturer before painting a
hose. Never paint the couplers. Hose deterioration due to corrosive materials may
result in personal injury.

Tools
DANGER: To prevent serious personal injury or death,
• This pump is designed for torque wrench applications and should never be used for
lifting loads.
• Do not exceed rated capacities of the tools. Excess pressure may result in personal
injury.
• Read and understand all safety and warning decals and instructions for devices
attached.
• Inspect each tool and coupler before each shift or usage to prevent unsafe conditions
from developing.
• Do not use tools if they are damaged, altered or in poor condition.
• Do not use tools with bent or damaged couplers or damaged port threads.
• Avoid pinch points or crush points that can be created by the tool.
• Never use extreme heat to disassemble a hydraulic tools. Metal fatigue and/or seal
damage will result and can lead to unsafe operating conditions.
• The guide cannot cover every hazard or situation so always do the job with SAFETY
FIRST.
IMPORTANT
• Keep the tool clean at all times.
• Use an approved, high-grade pipe thread sealant to seal all hydraulic connections.
PTFE 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 pinched by the coupler and broken off
inside the pipe end. Any loose pieces of tape could travel through the system and
obstruct the ow of uid or cause jamming of precision-t parts.
• Always use protective covers on disconnected quick couplers.

uid, or delivers only
enough uid to advance
connected components
partially or erratically or
operation to slow.
1.Fluidleveltoolow. 1. Add uid, refer to lling the pump
reservoir in Initial Setup section.
2.Loose-ttingcouplerto
component.
2. Verify quick-disconnect couplings are
completely coupled. Couplers may need to
be replaced because ball check does not stay
open due to wear.
