In order to prevent undue wear on the elevating screws and gears， it is important to keep the  
Base free from dirt and grit. It is recommended that the Base be cleaned with spirits or other
cleaning fluid regularly and sufficient oil be applied to the elevating screwsto provide lubrication.
When making tests， always be sure that the ball retainer is tight. This will prevent damage to
the machine and insure accurate tests. The 10mm. ball should be replaced from time to time
as wear occurs. To replace ball， unscrew retainer and insert new ball.
It is very important that the ram be pushed back as far as it will go before making a test. This
may require considerable pressure on the crank， especially with a new machine. It is equally
important to make sure that the ram does not get pumped down at any time more than 5/16 If.
Ifthe ram is pumped down further， air may enter the hydraulic system and the Test Head will
no longer be calibrated correctly. Air in the hydraulic system can be removed as explained in
Directions for Changing Oil， in the maintenance manual， page 2.
On older machines， examine the Test Head periodically for oil leakage around moving parts，
packing nuts and set screws. If excessive oil leakage is apparent， it may be necessary to replace
a-rings and to change the hydraulic oil.
When servicing or repairing the Test Head， it is recommended that all severely worn parts be
replaced with new parts. It is important that all nuts with worn threads or slots be discarded
and replaced in order to facilitate reassembly and to minimize further repairs.
