If the tilt rate is greater than the specifications,
lower the mast and remove the load from the
forks. Install a valve between the port at the
front of the tilt cylinder and the hydraulic line.
The valve must be able to completely shut off
the flow of hydraulic oil. Put the load on the
forks again. Close the valve. Tilt the mast for-
ward just past the vertical position. If the mast
continues to tilt SLOWLY forward, the seals on
the piston are leaking.
4.
If the mast does not move, open the valve and
check the movement again. If the mast moves
forward when the gate valve is open, check for
leaks in the hydraulic lines and fittings. If no
leaks are found, the main control valve can be
worn or damaged. Remove the load from the
forks when the checks are complete.
