OVERLOAD WARNING DEVICE
Description
NOTE:The excavator must be equipped with the optional boom load holding valve to installed for the overload warning device.
The overload warning device (if equipped) senses hydraulic pressure in the boom lift circuit. When the hydraulic pressure in the boom lift circuit reaches a predetermined pressure setting, a buzzer will sound that indicates an overload condition.
If the buzzer sounds, immediately move the arm closer to the excavator and lower the boom. Reduce the size of the load before attempting to re-lift the load.
Warning
AVOID INJURY OR DEATH
Do Not work or stand under raised work equipment or attachment.

Important
Maintenance work must be done at regular intervals. Failure to do so will result in excessive wear and early failures. The service schedule is a guide for correct maintenance of the Bobcat excavator. The decal (Item 1) [Figure74] is located on the inside of the tailgate. (See SERVICE SCHEDULE on Page 103.)
Check the following items before each day of operation:
•Operator Canopy or Cab (ROPS / TOPS) and mounting hardware.

Pressure Washing Decals
•Never direct the stream at a low angle toward the decal that could damage the decal causing it to peel from the surface.

Important
This machine is factory equipped with a U.S.D.A. Forestry Service approved spark arrester exhaust system.
The spark arrester muffler, if equipped, must be cleaned to keep it in working condition. The spark arrester muffler must be serviced by dumping the spark chamber every 100 hours of operation.
On some models, the turbocharger functions as the spark arrester and must operate correctly for proper spark arrester function.
If this machine is operated on flammable forest, brush, or grass covered land, it must be equipped with a spark arrester attached to the exhaust system and maintained in working order. Failure to do so will be in violation of California State Law, Section 4442. PRC. Refer to local laws and regulations for spark arrester requirements.
