4) Tabletop tilts very slowly 

o) Pinched hose. 

 

 

p) Velocity fuse locking. 

 

 

q) Incorrect counterbalance valve 

setting. 

o) Examine all hoses for kinks. 

Straighten kinked hose(s) to restore oil 

flow. 

p) Counterbalance setting is incorrect. 

Contact Vestil for assistance. 

q) Decrease counterbalance setting by 

turning socket head screw 

counterclockwise. 

5) Tabletop does not tilt 

r) Velocity fuse locking. 

s) Control transformer fuse blown. 

 

t) No supply voltage. 

 

 

u) Bad connection in control circuit. 

 

v) Something physically blocking the 

tabletop. 

w) Solenoid valve malfunctioning  

 

 

 

x) Solenoid valve or suction hose screen 

plugged. 

r) See solution P above. 

s) Test with multi-meter. Replace if 

necessary. 

t) Make sure power cord is plugged in. 

Also check fuses, breakers, and 

overloads to determine cause. 

u) Test all parts of circuit with multi-

meter. 

v) Walk around the table and look for 

items, material, etc. interfering with table 

movement.  

w) Check solenoid with multi-meter on 

diode-check function (measuring Ohms 

does not accurately test coil). 

x) Remove, inspect, and clean the valve.
