Upper limit switch out of
adjustment
the unit does not lower, remove the
connector to the coil and measure
the coil resistance. It should be
around 39 ohms. If it’s open, or
shorted replace the coil.
Loosen hydraulic line at pump to
relieve pressure build up. Re-
adjust limit switch so unit stops at
7 to 8 inches above the ground.
Look for binding in chain or rollers
Unit keeps blowing fuses when the
raise lever is pressed
Shorted solenoid for motor raise Remove the wire to the solenoid coil
on the pump motor. Measure the
resistance; it should be around 19
ohms. If it is nearly zero ohms
replace the solenoid.
Lifting height is not longer achieved Hydraulic oil level is too low Re-fill hydraulic oil when forks are
lowered.
Unit jerks when lifting Air in the system Open vent screw on the lift cylinder
with forks lowered all the way down.
Lift forks with vent screw open until
oil is free from air bubbles. Close the
vent screw
Forks raise, then drift down Check valve or Solenoid valve
leaking (contamination holding open
the lowering valve or the check
valve)
Remove & inspect.
. Remove any load from the forks.
. Remove the nut holding solenoid
coil on the valve stem, and then
unscrew the valve from the
manifold.
. Inspect the valve for contaminants,
and
the valve’s o-rings and back –up
washers for cuts, tears, and other
damage.
. With valve immersed in mineral
spirits or kerosene, use a thin tool
such as a small screwdriver or a
small hex wrench to push the poppet
in and out several times from the
bottom end of the valve. The valve
should move freely, about 1/16”
from closed to open position. If it
sticks in, the valve stem could be
bent and will need to be replaced if
it doesn’t free up after cleaning.
Blow the valve off with a
compressed-air gun while again
pushing the poppet in and out.
