Autoquip SERIES 35 TILTERS - Manual (Page 34)

PROBLEM POSSIBLE CAUSE AND SOLUTION
Tilter won’t lower. • The solenoid coil may be incorrectly wired,
burned out, not rated for the voltage, or the line
voltage may be excessively low. Check voltage
near the coil.
• The velocity fuse may be locked. Do not
attempt to remove the velocity fuse. The
following steps should be followed:
1. Remove the load from the tilter. Inspect all
fittings, hoses, and other hydraulic components
for leads or damage.
2. If no leak or damage is noticed, attempt to
pressurize the lifting cylinder by depressing the
“UP” button on the controller for a few seconds.
Immediately up releasing the “UP” button,
depress the “DOWN” button. If the tilter starts to
lower, continue pressing the “DOWN” button
until it is in the fully lowered position.
3. If the tilter does not lower after trying Step 2,
wait approximately 10 – 15 minutes for the
pressure in the hydraulic system to equalize.
Then, depress the “DOWN” button until it is in
the fully lowered position.
4. Once the tilter is in the fully lowered position,
bleed the air from the hydraulic system by
depressing the “DOWN” button. Hold the
“DOWN” button for approximately 60 seconds.
This step may need to be repeated several
times to fully remove the air in the system by
raising the tilter to 50% of its travel and lowering.
• Should the above steps not correct the problem,

action.
