1.3 Hydraulic Tensioner Safety Precautions -
CAT 3600 Connecting Rod Tensioner
WARNING
Failure to observe the following precautions may result in
death or serious personal injury.
Hydraulic tensioners must be installed, operated and
maintained only by trained and skilled personnel familiar
with the safe operation of high pressure tensioning devices
and related equipment.
• Always wear eye protection, gloves and boots when working
near a pressurized hydraulic system.
• When working on site, the work area should be roped-o 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.
• Never exceed the maximum working pressure of the hydraulic
tensioner (21,750 psi or 1500 bar).
• Do not exceed the maximum allowable stroke of the tensioner
pistons. An indicator (located on each tensioner sleeve) will
appear when the sleeve piston has reached its maximum
stroke. STOP pressurizing the tensioners immediately if this
indicator becomes visible.
• Never stand in-line with the bolt axis while tensioning or de-
tensioning is in progress. If the bolt or stud 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 tensioners
only when absolutely necessary and only when the pressure is
steady. Continually observe the pump pressure gauge and the
touchscreen HMI pressure readout.
• Keep hands, fingers and other body parts clear of the
tensioner during tensioner operation. Do not attempt to move
or reposition the tensioner while it is pressurized.
• High pressure hydraulic equipment can be very dangerous if
misused. Keep away from oil leakages at high pressure. Liquid
escaping from highly pressurized equipment has sucient
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 and the touchscreen HMI
pressure readout both indicate zero (0) psi/bar before
tightening fittings or beginning any repairs.
• Never attempt to disconnect a hydraulic coupler while it is
under pressure.
• Do not move or lift the hydraulic tensioners using the hydraulic
hoses and fittings.
• Hoses should not be twisted or bent too sharply. The bend
radius should not be less than the manufacturer’s specified
minimum bend radius for your hose type.
• Before pressurizing the system, carefully inspect all hydraulic
hose assemblies. Replace any damaged, crushed or kinked
hoses immediately.
• Before pressurizing the system, be sure that all hydraulic
hoses are connected. Each male coupler must be connected
to a corresponding female coupler. Verify that each coupler is
fully engaged and securely locked into position by physically
pulling on the connection.
• Never pressurize the back of a disconnected male coupler.
Male couplers cannot withstand high pressures when
disconnected. Serious personal injury could result if the
coupler fails while it is disconnected and under pressure.
• Use caution when pressurizing a system. Pressure can rise
faster than anticipated. Continuously monitor the pressure
gauge and the touchscreen HMI pressure readout during
pressurization. Be prepared to stop the pump immediately at
any time.
• Never leave a pressurized system unattended. If you must
leave the area, stop the pump and ensure that the hydraulic
pressure gauge and the touchscreen HMI pressure readout
both indicate zero (0) psi/bar.
• Use only the Smart Tensioning Pump (model No. 498-6540
or 498-6541) to power the tensioners. The tensioners are
designed for use only with this pump.
• Any maintenance or repairs to the tensioners, the pump or
related components must be performed with the equipment in
the unpressurized state (0 psi/bar).
