SECTION 11:  TROUBLESHOOTING 
 
 
A. Equipment does not rise; pump is running: (see also Section M) 
 
1.  The motor rotation may be reversed.  See the installation procedure on how to jog 
the motor to check for proper rotation. If the lift has been installed for some time and 
the motor is 3-phase, it is possible that the plant wiring “upstream” has been 
changed during plant maintenance or alteration, and the motor is now running 
reversed. A hydraulic pump can only run reversed for a short time...

 
 
SECTION 11:  TROUBLESHOOTING (Continued) 
 
10. The down solenoid may be energized due to incorrect wiring, or mechanically stuck 
open, bypassing fluid. 
A.  Check the wiring.  Hold a non-magnetized screwdriver to the top of the down 
solenoid coil and press the up button.  If you can feel magnetism, the wiring is 
faulty. 
B.  Lightly tap the down solenoid to seat it properly.  Do not bang it hard, as internal 
stem parts may be permanently damaged. The solenoid coil can be removed, 
and the down...

 
 
 
SECTION 11:  TROUBLESHOOTING (Continued) 
 
6.  Equipment in which the cylinders are field installed may have incorrect alignment of 
cylinders, causing binding. Measure and ascertain that the cylinders are in the 
correct alignment with the equipment and with each other. Binding cylinders will 
often cause a “shuddering” vibration when the equipment is operating. 
7.  Oil may be too thin for ambient temperatures. See A-12 
 
C.  Motor labors or heats excessively:  
1.  Voltage may be too low. See...

 
 
 
SECTION 11:  TROUBLESHOOTING (Continued) 
 
F. Equipment lowers too fast: 
 
CAUTION! This can develop into a dangerous condition, the equipment reaching 
destructive speed.  Find and correct this condition before allowing use of this 
equipment. 
 
1.  Check for leaking hoses, particularly cracked fittings or other damage caused by 
equipment motion near the equipment and power unit, over-tightening of fittings until 
they develop hairline cracks.  Check underground conduits for evidence of fluid...

 
 
SECTION 11:  TROUBLESHOOTING (Continued) 
 
7.  Improper oil for ambient temperatures.  Oil may be too thick, causing improper 
operation of velocity fuses (if used).  See “Component Information’ on velocity fuses. 
Warm the cylinders by wrapping heat tape (of the type used for water pipes) around 
the cylinder. Later, after operation is normal, change to proper oil as per “Fluid 
Recommendations”. 
8.  Binding Cylinders. See B-6 
 
I.  Equipment raises slightly, then equipment stops and motor...

 
 
SECTION 11:  TROUBLESHOOTING (Continued) 
 
3.  Although very rare, high voltage spikes may be coming in on the power lines at 
random, burning out coils.  This cannot be detected with a power company recorder, 
A “Varistor” can be purchased and easily installed on control systems to protect the 
coils.  More severe cases on both 115V or 24V control systems may need a special “ 
High Insulation Transformer” in place of the standard control transformer. 
 
M.  Equipment does not lift rated load, or...
