Chapter 8 - Operation
3–2–1 Forward and backward
CAUTION
• Use the arrow decal to determine which way is forward and which way is backward. • A warning buzzer will beep regularly when the travel control lever is being operated. Depress the foot switch and operate the travel control lever to the traveling direction.
3–2–2 Steering
In order to change course, step on the foot switch while using the steering switch.
3–2–3 High-speed traveling
DANGER
• Steer straight while traveling at high speeds. • Switch to either medium or low speed before turning. • The platform will swing widely, and there is a possibility the operator will be thrown from the platform.
CAUTION
• Do high-speed traveling only when the traveling surface is flat, you have a good forward view, and you have to travel for a long distance. • Under normal circumstances, keep the travel speed select switch on “LOW SPEED.” • Engine rotations become high automatically when high-speed traveling. Avoid changing your traveling speed because doing so creates a big shock. • High-speed traveling is only possible when the boom is fully retracted, the boom angle is under the horizontal, and the rotation angle is under 10°. In all other situations, even if you turn the travel speed select on “HIGH SPEED,” you will be able to travel only at low speeds.
3–3 Boom operation
DANGER
Do not push the boom or platform to the ground, or use them to crash into objects, or push things up.
WARNING
Before rotating the boom, make sure it will not catch people or things, and make sure there are no obstacles in the way. The turntable protrudes 850 mm (2 ft – 9 in) beyond the width of the chassis when rotating the boom, so watch the turntable movement and make sure that no person or obstacle is around the turntable. If the boom cannot be raised and the rear of the turntable cannot be seen, have a guide assist you.
CAUTION
• Before rotating the boom, make sure the rotation lock pin has been removed. • If the boom is rotated while the machine leans, the rotation may be rough. • Pay attention to how the turntable moves when rotating it. • If you cannot raise the boom, or are not able to see the rear of the turntable, perform the rotation under the supervision of a guide person.
3–4 Platform rotating operation
CAUTION
• Keep the platform straight while traveling. • When rotating the platform neck, make sure to stop the machine, and check the safety of the surrounding area. Depress the foot switch and operate the platform rotation switch to rotate the platform.
