Operator Safety

For models equipped with factory-installed Roll Over 
Protection System (ROPS).

OPERATIONAL WARNINGS
  •  Always use the seat belt when the roll bar is in the 

raised position.

  •  Never use the seat belt when the roll bar is in the 

down position.

  •  Remember there is no roll over protection when 

the roll bar is in the down position so it is very 
important to always keep the roll bar in the raised 
position whenever possible.

  •  Lower the roll bar to the down position only when 

it is absolutely necessary.

  •  Check for overhead clearances before driving 

under any objects.  Do not allow roll bar to contact 
low overhanging obstacles such as tree branches 
and guide wires.

  •  Never remove the roll bar from the vehicle.
  •  Do not exceed the machine weight rating of the 

roll bar.

  •  Read and follow all of the instructions shown 

below regarding the inspection and maintenance 
of the roll bar structure and the seat belt.

A ROLL BAR, like any other safety device, needs to 
be periodically inspected to verify that the integrity of 
the device has not been compromised through normal 
machine use, misuse, age degradation, modifications, 
or a roll over.

To maintain operator roll over protection and roll bar 
effectiveness:
  •  If a ROLL BAR becomes damaged for any reason, 

such as a collision, roll over or impact, the ROLL 
BAR must be replaced.  Small undetectable 
cracks can reduce the effectiveness of the ROLL 
BAR.  Never weld, straighten, or repair the ROLL 
BAR.

  •  Never alter the ROLL BAR by welding anything to 

it or by drilling additional holes.

 • BEFORE FIRST TIME USE - Inspect the ROLL 

BAR structure and mounting hardware for:

1)  Check to make sure the machine GVW (Gross 

Vehicle Weight), including attachments, 
restrained payload, fuel and operator, is not 
in excess of the maximum weight specified on 
the ROLL BAR label.

2)  Make sure there isn’t any missing, damaged, 

or loose mounting hardware.

3)  Make sure the ROLL BAR has been correctly 

and completely installed.

 • EVERY 100 HOURS - Inspect the ROLL BAR 

structure and mounting hardware for:

1)  Any cracks in the structure (structural members 

and/or welds).

2)  Significant corrosion on any part of the ROLL 

BAR structure or hardware.

3)  Missing, damaged, or loose mounting 

hardware

4)  Mounting hardware that is of a grade lesser 

than specified.

5)  Machine GVW (Gross Vehicle Weight), 

including attachments, restrained payload, 
fuel and operator, in excess of the maximum 
weight specified on the ROLL BAR label.

6)  Any modifications that have been made, such 

as unauthorized welds and holes.

7)  Any permanent deformation or twisting of the 

ROLL BAR structure.

8)  That the ROLL BAR label is still in place and is 

readable.

9)  That the ROLL BAR on-product warning labels 

are still on the ROLL BAR and are readable.

  •  If there is any doubt as to the condition of the 

ROLL BAR, remove the machine from service and 
contact your dealer for assistance.

leaks.  Make sure all hydraulic fluid connections 
are tight and all hydraulic hoses and lines are in 
good condition before applying pressure to the 
system.  If leaks occur, have the unit serviced 
immediately by your authorized dealer.

 26. WARNING: Stored energy device.  Improper 

release of springs can result in serious personal 
injury.  Springs should be removed by an 
authorized technician.

 27. Models equipped with an engine radiator: 

WARNING: Stored energy device.  To prevent 
serious bodily injury from hot coolant or steam 
blow-out, never attempt to remove the radiator 
cap while the engine is running.  Stop the engine 
and wait until it is cool.  Even then, use extreme 
care when removing the cap.
