Hydraulic/Mechanical Components General Service Procedures
Servicing Hydraulic Components
To service the hydraulic components, proceed as follows:
Before Beginning
Before beginning the service, proceed as follows:
1 Ensure that the unit is not pressurized with fuel. For dispensers, close and test shear valves.
Refer to
“Shear Valves” on page 6-70 .
2 Isolate the unit at the interface box (8800 Retail units only).
3 Shut off power to the unit. If the unit is a dispenser, shut off power from the involved STPs.
Use the OSHA lockout/tagout procedures at the station’s STP and dispenser breakers.
4
Wear eye protection for hydraulic service, where fluid lines or containing parts are serviced.
CAUTION
Open the nozzle into an approved container to bleed of the pressure. Some residual pressure
may remain.
5 Record the totals before you continue with the service procedures.
6 Continue with the required service procedures.
After Repairing
After repair, proceed as follows:
1 In the interface box, place the unit in normal operation. Power-up the unit.
2 Purge air and check for leaks after replacements or rebuilds. Refer to “Purging Air from
System” on page 6-9 .
3 Verify if the unit is operating properly.
4 Record the totals after the service and provide the totals (before and after) to the station, if fuel
was dispensed.
