Automatic fork leveling control
Operating the fork for forward tilting from the backward tilt position with the tilt lever knob switch pressed
stops the fork automatically in level position (with the mast in vertical position). The conditions vary as
follows depending on the lifting height and the load.
Actuation will be as indicated below when the mast is operated for forward tilting from the backward tilted
position with the tilt lever knob switch pressed:
• Pressing the tilt lever knob switch during forward tilting with high lifting height and load stops
forward tilting, but the hazard of falling is present depending on the conditions of the road
surfaces, etc. Never use this function for the purpose of any work.
• In the case of a vehicle with attachment, automatic fork leveling control poses a hazard if the
lever stroke is set to maximum during high lifting.
• In the case of a specialty model installed with heavy attachment, etc., the automatic fork leveling
control may not be provided.
Key-off lift lock
1. Integral control valve has been newly designed for mast control, and the lift hydraulic circuit is modified
accordingly.
2. Lowering is disabled if the lever is operated for lowering when the key switch is turned OFF.
3. Since the lift lock solenoid valve is provided to the lift hydraulic circuit, the solenoid valve remains
closed while the key switch is turned OFF, preventing the lowering if the lift lever is operated for
lowering. To lower the fork, turn the key switch ON and operate the lever for lowering.
Possible vehicle weight for installing the mast control
When installing a heavy attachment, etc. to a specialty model, the mast forward tilt angle is set to approx.
1 degree. No automatic fork leveling control is provided for high lifting height.
Not loaded Loaded
High lifting height (Approx. 2m or
more) Stops with the mast held in
vertical position
Does not tilt forward
Low lifting height (Less than approx.
2m) Stops with the mast held in
vertical position
Stops with the mast held verti-
cal or tilted backward by about
1 degree depending on the
load.
