2 1) Prepare for Shutdown a) A 360 degree walk around of the pumping unit is required to be completed before shutting down or working around a pumping unit. b) Verify key components are in safe and proper working condition by visual inspection, including: -unit guards are in place -equalizer bearing is functioning without restriction and properly lubed -saddle bearing is functioning without restriction and properly lubed -crank/wrist pin is functioning without restriction and properly lubed -counter weights are tightly fastened and that the bolts/nuts appear to be tightened down. Identify ALL isolation points (JOG/AOJ Switch, Electrical Panel Box, Unit Brake). Document these on your isolation log on the JSA. A Supervisor must be called when shutting down an in service unit so that the lease operator may be notified of shutdown.
