Active mast front tilt angle control
According to a lift and to a load, the angle at which the mast can
be tilted forward is automatically controllable within a range of
angles illustrated below:
CAUTION!
• If a load should be moved up while tilting the fork forward at a
low lift, there is a fear that the vehicle may tipover when the
fork stops at the position having a tilt angle beyond the speci-
fied angle range. Never handle any load, therefore, while tilting
the mast, with the load moved up.
• With a high load at a high lift, never match the load (mast
angle) by controlling the mast forward tilting angle, since it
involves the fear that the vehicle may tip over.
• Even with a load positioned within the allowable angle range,
never tilt the mast beyond its vertical position, or the vehicle
may tipover, losing its stability forward and backward. Never
tilt the mast forward, with a load moved up.
• Some specialty models onto which a heavy attachment is
mounted may not be equipped with the mast forward tilt con-
trol. Confirm a BT dealer in advance.
• Once you have mounted or replaced any attachment on a fork
lift model, ask a BT dealer for an inspection.
• If you use two or more removable attachments alternately, the
heaviest one should be used to carry out matching (SAS set-
ting). Ask a BT dealer for help in advance.
Note:
With the fork positioned at the top dead end, a high pressure
(relief pressure) may remain in the lift cylinder. This high pres-
sure causes the vehicle to judge that it has a high load even
unless loaded. As a result, the mast will be hindered from tilting
forward. In this case, move the fork a little downward from the
top dead end (to release the pressure) and the mast may be
tilted forward.
