Personal injury can result from contact with refrig-
erant.
Contact with refrigerant can cause frost bite. Keep
face and hands a way to help prevent injury.
Protective goggles must always be worn when re-
frigerant lines are opened, even if the gauges in-
dicate the system is empty of refrigerant.
Always use precaution when a fitting is removed.
Slowly loosen the fi tting. If the system is still un-
der pressure, release it slowly in a well ventilated
area.
Personal injury or death can result from inhaling
refrigerant through a lit cigarette.
Inhaling air conditioner refrigerant gas through a
lit cigarette or other smoking method or inhaling
fumes r eleased from a flame contacting air con-
ditioner r efrigerant gas, can cause bodily harm or
death.
Do not smoke when servicing air conditioners or
wherever refrigerant gas may be present.
Use a certified recovery and recycling cart to prop-
erly remove the refrigerant from the air condition-
ing system.
NOTICE
If th
e refrigerant system has been open to the outside
air (without being plugged) for more than 30 minutes,
the receiver-dryer must be replaced. Moisture will en-
ter
an open refrigerant system and cause corrosion
which will lead to component failure.

Rollover Protective Stru cture
(ROPS )
- Inspect
SMCS Code: 7323-040; 7325-040
S/N: DBD1-Up
NOTICE
Do not attempt to straighten the ROPS structure. Do
not repair the ROPS by welding reinforcement plates
to the structure.
If there are any cracks in the welds, in the castings, or
in any metal section of the ROPS, consult your Cater-
pillar dealer for repairs.
1. Inspect the ROPS for loose bolts. Inspect the
ROPS for damaged bolts. Replace the damaged
bol
ts and the missing bolts with original equipment
parts only. Torque the bolts to 1050 ± 150 N·m
(775 ± 110 lb ft).
Note: Apply oil to all ROPS bolt threads before
you install the bolt. Failure to apply oil can result in
im
proper bolt torque.
2. Operate the machine on a rough surface. Replace
t
he ROPS mounting supports if the ROPS makes
a noise or if the ROPS rattles.
I
f there are any cracks in the welds, in the castings,
or in any metal section of the ROPS, consult your
Caterpillar dealer for repairs.
