[4] SPEED SELECTOR ROTARY SWITCH: S10
When it is required to operate the Crane at low speed, the maximum
speed of the Crane is limited if the speed selector rotary switch is set
to any of 1, 2 and 3, and speed control at low speed can be
performed smoothly.
Set value of speed selector rotary switch
1 ··············· Micro speed 1
2 ··············· Micro speed 2
3 ··············· Micro speed 3 (User micro speed mode)
STD ·········· Ordinary (Linked operation with acceleration
dial
R1)
In the outrigger operation, the setting is automatically set to STD.
[5] ACCELERATION DIAL: R1
This is used to adjust the maximum engine speed.
1. Set the acceleration dial (engine speed) to any position.
(The maximum engine speed can be set to increase on the +
side.)
2. Set the speed selector rotary switch (S10) to STD.
3. When each operation lever is pushed down, the Crane speed
increases according to the operation amount and the engine
speed increases also.
NOTES
1. When the speed selector rotary switch is set to STD, the acceleration dial is set to MAX (turn the dial
fully to the + side) and each operation lever is pushed down to the maximum, the Crane speed
becomes the maximum (engine speed also becomes the maximum).
2. When the speed selector rotary switch is set to STD and the acceleration dial is set to MIN (return the
dial fully to the - side), engine speed does not increase even if each operation lever is pushed down to
the maximum.
