Daily Inspections
Before the start of each day’s testing, do a quick inspection of the load unit. Following are typical things
that should be checked daily:
l
Ensure that there are no leaks from lifts or locks.
l
Check the drip pan and ensure that there are no leaks from the actuator, hydraulic service
manifold, servovalve, or accumulators.
l
Ensure that electrical connections are tight, with no frayed or poorly routed cables.
l
Ensure that hoses are routed properly, not wearing, and the fittings are not leaking.
l
Hoses must be routed as to avoid direct heat sources, moving, or abrasive equipment.
l
Check actuator speed control functionality.
If any problems are encountered, they should be repaired before operating the load unit.
Clean the Columns
The crosshead locks cannot securely clamp the crosshead to dirty or greasy columns. You will need
ethanol and lint-free cloths to perform this procedure.
Warning:
The crosshead can slide down the columns.
Crosshead cleaning takes place in a crush zone where pinched fingers and crushed hands
can occur.
Do not position yourself in a crush zone. Always lock the crosshead after moving it. Always turn
off hydraulic pressure before cleaning the columns. Wait two minutes for pressure to bleed off
before starting work.
1. Ensure that the crosshead is locked.
2. Using a clean, lint-free cloth, clean the exposed surfaces of the columns with ethanol.
3. If the load unit does not have hydraulic crosshead lifts, skip ahead to the next step. If the load
unit has hydraulic crosshead lifts, complete the following steps:
A. Turn on system electrical power.
B. Apply high hydraulic pressure to the load unit.
4. If there is a specimen in the load unit, remove it.
5. Unlock and move the crosshead to expose the uncleaned section of the columns.
6. Lock the crosshead.
7. If hydraulic pressure has been turned on, turn it off. Wait two minutes for the pressure to bleed
