5 – Preventive maintenance
Preventive maintenance
Prepare to service the intensifier
Consider doing preventive maintenance on both high-pressure ends to reduce unplanned downtime.
Required parts, tools, and materials
13/16-inch open-ended wrench or socket (high-pressure water fitting)
7/8-inch open-ended wrench (low-pressure water fitting)
1-inch open-ended wrench (output adapter)
1-1/6-inch open-ended wrench (high-pressure water fitting)
Do this task when the pump is running in cooling mode.
WARNING
Working on this equipment while it is energized can cause a potentially hazardous situation, which, if
not avoided, can cause serious injuries or death.
Use a lock out–tag out program whenever workers engage in service or maintenance operations on
machines that are capable of exposing them to hazardous energy from unexpected energization,
startup, or release of stored energy. This energy can be from electrical, hydraulic fluid, or water
sources.
Before doing a service or maintenance, the following steps must be done in sequence.
1. Turn off the machine.
2. Disconnect or isolate the machine from the energy source(s). Refer to the specific provisions of
the employer’s energy-control procedure.
3. Apply the lock-out and tag-out devices to the energy-isolating device(s).
4. Release, restrain, or otherwise render safe all potential hazardous stored or residual energy. If a
possibility exists for reaccumulation of hazardous energy, regularly verify that such energy has
not reaccumulated to hazardous levels.
5. Verify the isolation and deenergization of the machine.
CAUTION
Overtightening a fitting can cause it to fail. Use 2 wrenches when loosening or tightening a
high-pressure connection. Using only 1 wrench can increase bending stress to the parts and cause
damage or premature failure.
Do not use an adjustable wrench on high-pressure fittings.
Use clean hands when changing high-pressure parts such as high-pressure water seals.
