DANGER
!
To avoid personal injury, NEVER go under the tilter platform until the
load is removed and the platform is securely blocked in the open
position. See "Blocking Instructions" section.
Tilter lowers very slowly.
•
The down-solenoid is not operating properly due to
dirt or damage.
•
Check for pinched tubing or hose. Where pipe is
used, check for obstruction in the line.
•
The oil is extremely viscous due to low ambient
temperatures. Add or replace with lower weight oil
that stays thinner in cold conditions (5W-15, etc.)
PROBLEM
POSSIBLE CAUSE AND SOLUTION
Tilter raises, then lowers back
slowly.
•
The "Down" solenoid may not be seating. Remove
the solenoid coil and check again. If the tilter does
not hold with the solenoid coil removed, the down
valve cartridge should be removed and cleaned or
replaced as necessary.
•
The oil line, hose, or fitting may be leaking. Check
and repair if necessary.
•
The “check valve” in the pump assembly may not
be seating. This is indicated by the pump shaft
and motor turning backward on their own with no
power applied. Generally, this condition can be
heard. Replace the pump assembly.
