K. DAILY INSPECTION & MAINTENANCE CHECKLIST (POWER UNIT)
Farr recommends that the following inspections and maintenance procedures be performed before each use, and at least once per
day when the equipment is in steady use, in the sequence in which they are listed. Rigorous inspection and maintenance, especially
lubrication, is essential in order to ensure that your equipment always meets specifications, and to prevent catastrophic failures that
can severely damage your equipment and cause worker injury.
If using a stand-alone power unit, perform the following inspection and maintenance procedures before each use, and at least once
per day when the power unit is in steady use:
Do not perform any maintenance while the power unit is energized (electric) or if the engine is running (diesel). Ensure the electri-
cal supply is locked out, or, if using a diesel power supply, ensure that the engine is locked out or the starting mechanism otherwise
disabled.

1.
Visually inspect all electrical lines and visible connections. If your unit is NOT explosion proof, open the electrical en-
closure and VISUALLY inspect contacts and connections for signs of corrosion or arcing. Do not open explosion-proof
enclosures.
2.
Visually inspect main electrical line between main power source and power unit.

5.
Perform a visual inspection of all parts. Check to ensure there are no loose or missing fasteners.
6.
Check hydraulic fluid level - ensure cold level is approximately half-way up the sight glass on the hydraulic fluid res-
ervoir.
7.
Perform a visual inspection to ensure there are no hydraulic fluid leaks - correct if necessary.
8.
Check that the main supply and return lines on the hydraulic fluid reservoir are both fully open.
9.
Apply grease to any grease fittings that your power unit may have. Apply grease to each fitting until grease is visibly
displaced from bearing, or as recommended by your power unit manual.
10.
Ensure supply and return connections at the power unit and at the equipment in use are fully made up.
NEVER PLACE HANDS INSIDE AN ELECTRICAL ENCLOSURE UNLESS YOU HAVE CONFIRMED
THAT THE POWER HAS BEEN DISCONNECTED AND LOCKED OUT
FAILURE TO ENSURE THAT THE SELF-SEALING SUPPLY AND RETURN LINES ARE FULLY
MADE UP MAY RESULT IN CATASTROPHIC EQUIPMENT FAILURE.
11.
Check hydraulic fluid filter back pressure (must be done while fluid is circulating). If needle on indicator gauge is in
the red zone, the filter should be changed the next time the unit is shut down
