3.1 General Bolting Safety Precautions
DANGER: Failure to observe the following precautions
during bolting procedures may result in serious personal
injury or death.
0
WARNING: Hydraulic nuts and tensioners must be
installed, operated and maintained only by trained and
experienced personnel familiar with high pressure
bolting devices and related equipment.
• Always wear eye protection, gloves and boots when working
near a pressurized hydraulic system.
A3
• When working on site, the work area
should be roped-off and all non essential
personnel not involved with the site
operation should be kept clear of the
working area.
• Before starting tensioning procedures,
be sure that all personnel are aware that
pressurization of high pressure hydraulic
equipment is about to occur.
• Check that the threaded portion of the hydraulic nut or
tensioner is screwed fully onto the stud, and that the thread
engagement is sufficient.
• Never exceed the maximum working pressure of the hydraulic
nut or tensioner.
• Do not exceed the maximum allowable ram movement (stroke)
of the hydraulic nut or tensioner.
• Always ensure that the piston is fully returned prior to
pressurization of the hydraulic nut or tensioner.
• Never stand in-line with the bolt axis
while tensioning or de-tensioning is in
progress. If the bolt should fail, serious
personal injury or death could result if
loose or broken parts become projectiles.
All personnel must be aware of this
potential hazard at all times.
• Allow personnel to be near pressurized
hydraulic nuts and tensioners only when absolutely necessary
and only when the pressure is steady. Continually observe the
pump pressure gauge.

• Never pressurize the back of
a disconnected male coupler.
Serious personal injury could result
if the coupler fails while under
pressure.
• High
equipment can be very dangerous
if misused. Keep away from oil
leakages at high pressure. Liquid escaping from highly
pressurized equipment has sufficient power to penetrate the
skin, which can cause blood poisoning. In the case of such an
accident, seek IMMEDIATE medical attention.
• Never attempt to repair leaks while the
system is pressurized. Be sure system
pressure gauge indicates zero (0) PSI /
BAR before making any repairs.
• Never attempt to disconnect a hydraulic
coupler while it is under pressure.
• Do not exceed the hydraulic hose
A1
manufacturer's specified minimum bend
radius. Do not use kinked hoses.
• Before pressurizing the system, carefully inspect all hydraulic
hose assemblies. Replace any damaged, crushed or badly
kinked hoses immediately.
• Use caution when pressurizing a system. Pressure can rise
faster than anticipated. Continuously observe the pressure
gauge during pressurization. Be prepared to stop pressurization
immediately at any time.
• Never leave a pressurized system unattended. If you must
leave the area, release the pressure and ensure that the release
(return-to-tank) valve on the pump is fully open.
• Read, understand and follow manufacturer's instructions when
0
using bolting equipment such as hydraulic nuts and tensioners.
Observe all safety precautions and hazard statements.
