Mast forward tilt control (forward tilt angle control)
(1) Possible forward tilting angle varies as shown in the figure below according to the lifting height and
load:
(2) If cargo is raised tilted forward for low lifting height, the stop position may come to the forward tilt
side than the control angle. Do not raise the cargo with the mast tilted forward same as previous
model.
(3) When the low load cargo is at the fully raised position, residual pressure from relief stop is detected
by the pressure sensor as high load, subsequently controlling the forward tilt angle. To enable
further forward tilting, lower the cargo slightly from the fully raised position and relief the pressure.
(4) When installing a heavy attachment to a specialty model, etc., the mast forward tilt control may not
be provided.
Caution:
• Don’t place overconfidence with the mast forward tilt control function.
• Although the forward tilt angle is reduced according to the load and lifting height, this does not
guarantee that the cargo does not fall or vehicle does not tip over under any conditions.
• Never tilt the mast forward from the vertical position with the cargo raised same as previous
model. Or the longitudinal stability will be degraded to cause the hazard of falling even under
allowable load.
• Never use the forward tilt control for any work.
Backward tilting speed control
(1) Controls (delays) backward tilting speed for high lifting irrespective of the load. In addition,
controlled speed continues if the cargo reaches the low lifting height from the high lifting height
while backward tilting is actuated.
(2) For low lifting height, the tilting is in full speed without any control irrespective of the load. Actuating
backward tilt with the tilt lever knob switch pressed controls (delays) the backward tilting speed as
long as the switch is pressed.
(3) When the lifting height enters low level from high level during backward tilting, the tilting speed is
controlled (delayed) as long as the tilt knob switch is pressed. Tilting reaches full speed (no speed
limit) when the tilt knob switch is not pressed.
