activate the tilt alarm.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
6. If the alarm does not sound, remove the machine
from service until the problem is corrected.
7. Lower the main boom.
Flashing Lights
The machine may be equipped with an optional flashing
light mounted on top of the cowling on each side of the
machine (refer to Figure 7.14).
Figure 7.14 – Flashing Lights
To inspect the flashing lights:
1. Turn the battery disconnect on, pull the emergency
stop button outward at the lower controls, and turn
the start switch on.
2. Visually check to see that the light is flashing ap-
proximately one flash per second.
Note
There is not an off switch for the flashing lights. The lights
cannot be turned off.
Sandblast Protection Kit
The optional sandblast protection kit protects the cylinders
from abrasion while sandblasting or from paint overspray.
Rubber covers (refer to Figure 7.15) protect each cylinder
rod as it extends and retracts. The covers prevent sand
and paint from damaging the cylinder seals and rod.
Figure 7.15 – Sandblast Protection Kit
To inspect the sand blast protection kit:
1. Inspect the covers while operating the machine to
ensure they are securely fastened and completely
cover the cylinder rod.
