Safety 

Lines, Tubes and Hoses

Do not bend high pressure lines.  Do not strike high pressure 
lines.  Do not install any lines that are bent or damaged.
Repair any lines that are loose or damaged.  Leaks can 
cause fires.  Consult your Rayco dealer for repair or for 
replacement parts.

Check lines, tubes and hoses carefully.  Do not use your bare 
hand to check for leaks.  Use a board or cardboard to check 
for leaks.  Tighten all connections to the recommended torque.
Replace the parts if any of the following conditions are present:

•  End fittings are damaged or leaking
•  Outer coverings are chafed or cut.
•  Wires are exposed.
•  Outer coverings are ballooning.
•  Flexible part of the hoses are kinked.
•  Outer covers have embedded armoring.
•  End fittings are displaced. Make sure that all clamps, 

guards, and heat shields are installed correctly.  During 

machine operation, this will help to prevent vibration, 

rubbing against other parts, and excessive hear.

Electrical Storm Injury Prevention

When lightning is striking in the vicinity of the machine, the 
operator should never attempt to operate the machine. If you 
are on the ground during an electrical storm, stay away from 
the vicinity of the machine!

Before Operation

Safety information is available in English for this machine.  
A list of some of the material is available in the Operation 
and Maintenance Manual, “Reference Material”.  Consult 
your Rayco dealer in order to obtain copies of the material.  
The information should be reviewed by every person that 
operates the machine. 
Clear all personnel from the machine and from the area.
Clear all obstacles from the path of the machine.  Beware 
of hazards such as wires, ditches, etc.
Make sure that all windows are clean.  Secure all doors in the 

closed position.  Secure the windows in the open position 
or in the shut position.

Guards (Operator Protection)

There are different types of guards that are used to protect 
the operator.  The machine and the machine application 
determines the type of guard that should be used. 
A daily inspection of the guards is required in order to check 
for structures that are bent, cracked or loose.  Never operate 
a machine with a damaged structure.
The operator becomes exposed to a hazardous situation if the 
machine is used improperly or if poor operating techniques 
are used.  This situation can occur even though a machine 
is equipment with an appropriate protective guard.  

Other Guards (If Equipped)

Protection from flying object and/or falling objects is required 
for special applications.  Logging applications and demolition 
applications are two examples that require special protection.
A front guard needs to be installed when a work tool that 
creates flying objects is used.  Mesh front guards that are 
approved by Rayco or polycarbonate front guards that are 
approved by Rayco are available for machines with a cab or 
an open canopy.  On machines that are equipped with cabs, 
the windshield should also be closed.  Safety glasses are 
recommended when flying hazards exist for machines with 
cabs and machines with open canopies.
If the work material extends above the cab, top guards and 
front guards should be used.  
Additional guards may be required for specific applications 
or work tools.  The Operation and Maintenance Manual 
for your machine or your work tool will provide specific 
requirements for the guards.  Consult your Rayco dealer for 
additional information.

Precautions for Welding on FRAME with 

ENGINE/MACHINE Electronic Control 

Unit (ECU)

Important: ALWAYS disconnect Electronic Control Unit (ECU) 
connectors, battery and engine control system-to-machine 
ground before welding on engine or machine.
High currents or electrostatic discharge in electronic 
components from welding may cause permanent damage

Safety Decals

The safety decals located on this machine contain useful 
and important information which will help you to operate 
your machine safely. The complete decal kit and location of 
each decal is given in the “Parts” manual. For your protection,
