变速箱控制 - 变速箱操纵杆是在操作员座椅右侧。 当您想换档时,将操纵杆左侧的黑色按钮推入。 按钮用于机械锁定操纵杆在当前的档位上。 最高档位的功能由最高档位控制 ( 4)设定。

行驶 (1) - 移动操纵杆到要求的前进速度上。 变速箱将在第二档和所选择的任何较高档位上自动换档。 当在一档和第二档之间换档时,需要手动换档。 最高档位控制 (4)用来设定升档的限制。 发动机必须运转,操纵杆必须移动至 "D" 位置,以便选择一个限制位。 "D" 表示 行驶(DRIVE) 位置。 当开关固定在 接通(ON)位置,实际档位指示灯将闪烁。 然后,实际档位指示器将来回在可选择的档位之间循环。 当松开开关时,最高档位将在显示器上设定。 显示器将显示最高档位四秒。 四秒后,显示器将回到实际档位。 操作员能用的最高档位决不能高于维修人员设定的最高档位。 操作员可用的最高档中的最低档位是前进的第三档。 变速箱将以最高限制档运行,直到机器断开或直到选择另一个档位。

注: 当发动机经受超速时,最高档控制允许变速箱升一个档位,以排除超速情况。

"2" - 第二档(SECOND SPEED)位置

"1" - 第一档(FIRST SPEED)位置

注: 本机器配备了发动机空档起动系统。 操纵杆不在 空档(NEUTRAL) 位置前,发动机不能起动。

空档(NEUTRAL) ( 2) - 当停放机器或起动发动机时,移动操纵杆到"N" ,N 是 空档(NEUTRAL) 位置。 当操纵杆在 空档(NEUTRAL)位置和接合停车制动器时,机器不应移动。

倒档(REVERSE) ( 3) - 移动操纵杆到"R", R 是 倒档(REVERSE)位置。 机器将向后退。
