c) Oil starvation-check filter on the pump by removing
the coil stem from the pump.
Note
:
do not
overtighten
the stem when reinstalling.
4. Tilter operating slowly:
a) Up cycle:
• Oil starvation—check filter in reservoir.
Oil viscosity—oil is too heavy or too thin.
Air in cylinder—cycle tilter with no load 2 or 3 times
and hold down the up button for 10 seconds after
bottoming out on each cycle.
b) Down cycle:
• Down valve dirty—remove and clean. Check oil
condition; replace if dirty.
Note:
do not
overtighten
the stem when reinstalling.
• Pinched hydraulic lines.
• Oil viscosity is too heavy.
5. Tilter raises, then fully lowers without power:
a) Down valve filter is dirty. Remove and clean.
Note:
do not
over torque when reinstalling down valve.
b) Leaking hydraulic lines or fittings (check for telltale
oil spots).
c) Check valve in pump, may not be seating properly.
Pump must be replaced.
6. Tilter will not lower when energized:
a) Down solenoid faulty. Check voltage of coil. Check
continuity of coil (could be burnt out).
b) Raise the lift to its maximum height.
c) Using only the chock assembly provided, place the
square tubing in the wheel tray sideways and adjacent
to the welded long lifting eye nut.
d) nsert the pin which is secured to the lift through the
holes provided in the wheel tray. Be sure the pin enters
both holes and through the center of the tubing.
e) Lower the lift until the wheels come in contact with
the chock and hold the “down” button for another 2
seconds.
f) Raise lift, remove and replace chock to its straight
position.
