New Holland 300 Series Service Manual page 16

INTRODUCTION
Your machine is equipped with an operator presence system to prevent the use of some features while the operator
is not in the operator's seat.
Never disconnect or bypass the operator presence system.
If the operator presence system is inoperable, then it must be repaired. Follow the test procedure ( Joystick and
Electro-Hydraulic (EH) control - Check loader arm and bucket hydraulic interlock (55.512)).
Reflectors and warning lights
You must use flashing amber warning lights when you operate equipment on public roads.
Air-conditioning system
The air-conditioning system is under high pressure. Do not disconnect any lines. The release of high pressure can
cause serious injury.
The air-conditioning system contains gases that are harmful to the environment when released into the atmosphere.
Do not attempt to service or repair the system.
Only trained service technicians can service, repair, or recharge the air-conditioning system.
Personal Protective Equipment (PPE)
Wear Personal Protective Equipment (PPE) such as hard hat, eye protection, heavy gloves, hearing protection, pro-
tective clothing, etc.
Do Not Operate tag
Before you start servicing the machine, attach a 'Do Not Operate' warning tag to the machine in an area that will be
visible.
Operator protective structure
Your machine is equipped with an operator protective structure, such as: a Roll Over Protective Structure (ROPS),
Falling Objects Protective Structure (FOPS), or a cab with a ROPS. A ROPS may be a can frame or a two-posted or
four-posted structure used for the protection of the operator to minimize the possibility of serious injury. The mounting
structure and fasteners forming the mounting connection with the machine are part of the ROPS.
The protective structure is a special safety component of your machine.
DO NOT attach any device to the protective structure for pulling purposes. DO NOT drill holes to the protective
structure.
The protective structure and interconnecting components are a certified system. Any damage, fire, corrosion, or
modification will weaken the structure and reduce your protection. If this occurs, THE PROTECTIVE STRUCTURE
MUST BE REPLACED so that it will provide the same protection as a new protective structure. Contact your dealer
for protective structure inspection and replacement.
After an accident, fire, tip over, or roll over, the following MUST be performed by a qualified technician before
returning the machine to field or job-site operations:
• The protective structure MUST BE REPLACED.
