CAUTION – POSSIBLE EQUIPMENT DAMAGE (CONT’D):
REMEMBER – POSSIBLE TIME DELAY:
Isolate the coil and/or pump motor from the power control by disconnecting the wires on the motor
terminal board, or slip the wires off the solenoid coil that is being serviced.
Always connect power cord to a properly grounded socket.
To prevent rubber bumpers from being cut off, replace base shroud parts carefully and evenly.
Before articulating or making any adjustments to the table, ensure no electrical or hydraulic hoses are
subjected to stress or pinching.
Tilt articulation must be activated while adjusting the cylinder rod to release the brake mechanism.
Failure to do this destroys the cylinder.
Do not remove back section cylinder without supporting back section. Limit switch may be damaged
if back section drops too much.
When replacing solenoid valves, carefully remove retaining washer and pressure spring to prevent
washer and spring from quickly expelling from the valve block.
Use care when unthreading solenoid valve housing from the valve manifold. Plunger is equipped with
a spring which may expel from the housing upon removal of the plunger housing.
When unscrewing spring guide from side of Control Block #2, threads may run out before spring is
fully relaxed. Hold spring guide tightly to prevent housing, spring and pin from flying out.
Failure to secure a tabletop section may result in sudden lowering of that section when hydraulic line
is opened.
When reinstalling power supply assembly, be aware of table-lock microswitch wires (blue twisted pair
wire). Handle carefully to avoid breaking solder connections.
Handle wire cables carefully, ensuring they do not get entangled in other components and wires do not
pull out of the plugs.
Before field-resetting of voltage switches, disconnect table from any external ac power source.
Insufficient clearance space will make repairs more difficult and time consuming. Refer to the equipment
drawing for minimum clearance for service/maintenance access requirements.
