Safety Information
• Do not move or rotate the swivel manifold while tool is
under pressure.
• Tightening and loosening nuts and bolts using Hydraulic
Torque tools involves little visible movement. The loads,
torques and pressures however can be extreme. Keep
your hands clear of the fastener and the reaction points
during the tightening process.
• Avoid unexpected start-up. The pump remote control is
for the tool operator only. It is recommended that one
person should operate both the pump and the tool.
• Stay clear of pinch points during tool operation. Tool
will require support during operation - do not place
hands or other body parts between reaction foot and re-
action surface. It is highly recommended that handles are
used with hydraulic torque wrenches.
• Never use force. Never hammer on the socket or tool to
enhance performance. If the nut will not turn with the
wrench being used @ 90% of tool maximum torque/
pressure, a larger size tool is required.
• Occasionally, due to fatigue or capacity limits, square
drives and hex drives can fail during use, in the event of
such failure the torque wrench may jump or fall away
from the fastener / application. Operators should be fully
aware and consider this possibility during their risk as-
sessment prior to tool operation.
• Use the right tool for the job. Do not force small tools or
attachments to do the job of a larger tool. Do not use a
tool for purposes not intended.
• Ensure the ratchet size corresponds to the fastener size
being tightened or loosened. Using the incorrect ratchet
can cause the tool to become unstable and lead to prema-
ture / catastrophic tool failure.
• Proper torque reaction is essential
• The reaction structure must be strong and rigid
enough to accommodate the forces from the hy-
draulic torque wrench. Inspect the application for
suitable reaction points prior to applying the torque
wrench. If in doubt, contact the tool supplier for ad-
vice.
• Tapered surfaces are generally unsuitable as the
torque wrench will 'ride' or 'climb up' the taper
causing adverse tool loads. Ensure the reaction face
is firmly abutted against a stationery object (i.e.an
adjacent nut, flange, equipment housing etc.) Note:
be aware that untightened nuts being used as a reac-
tion point may spin when the load is applied to the
fastener being tightened.
• Do not place packing pieces, spacers etc., between
the reaction foot and the reaction point. Reaction ac-
cessories are available to increase the access to reac-
tion points to ensure safe operation / reaction.
• Wherever possible, particularly in overhead applica-
tions, the tool should be 'mechanically' supported to
prevent any sudden movement or displacement (fall-
ing). Where this is not possible the operator must
support the weight of the tool in a safe manner,
avoiding pinch points at all times. When handling

and lifting the hydraulic torque wrenches considera-
tion must be given to the combined weight of the
tool and any additional reaction accessories.
• Ensure that the hydraulic hoses and hose connec-
tions are well clear of any obstructions and pinch or
reaction points. Tools should be handled and manip-
ulated around the application in such a manner as to
prevent the hose from twisting and rotating.
• Then, and only when all the above have been
checked, apply momentary pressure to the system to
ensure correct tool placement. In case of doubt, stop
and readjust/reposition the reaction foot.
• Stop operation immediately if a gap appears between the
powerhead and the link. check link pin connection.
• Never adjust the hydraulic pressure regulator with the
tool on the application. Refer to the setting up instruc-
tions.
• During prolonged operation frequently check hydraulic
couplings are fully connected and tight, e.g. ensure cou-
pling have not 'backed off'.
• Do not operate tools with missing guards, cover plates or
screws. Guards and cover plates prevent contact with
moving internal parts of tools; if missing or damaged,
they must be replaced before the tool is used again.
• Moving equipment. Do not use hydraulic hoses, swivels,
pump power or remote cables as means of moving the
equipment. Release any residual hydraulic pressure in
accordance with pump instructions.
• Disconnect the power supply and depressurize the hy-
draulic system before disconnecting or connecting hoses,
fittings or accessories or adjusting or dismantling the
tool.
• Regularly inspect tool, power pack, hoses, connectors,
electric cables and accessories for visual damage. Refer
to user manual for correct tool and pump maintenance
and pre-operation checks.
• Break out (fastener loosening) shock load may damage
internal tool components. Always check and confirm
tool operation if sudden shock loads have occurred dur-
ing tool operation.
Projectile hazards
• The operator and all personnel in close proximity must
always wear impact-resistant eye (to En166) or face pro-
tection when involved with or near the operation, repair
or maintenance of the tool or changing accessories on
the tool. Even small projectiles can injure eyes and cause
blindness.
• Serious injury can result from over-torqued or under-
torqued fasteners, which can break, or loosen and sepa-
rate. Such fasteners can become projectiles.
Noise hazards
• High sound levels can cause permanent hearing loss and
other problems such as tinnitus. Use hearing protection
as recommended by your employer or occupational
health and safety regulations.
