3.2  Safety Sign Explanations

1.   Warning!

Always wear the appropriate PPE during 
operation:

A hard hat.

• 

Heavy gloves.

• 

Hearing protection.

• 

Protective footwear with steel toes 
and slip resistant soles.

• 

Protective glasses, goggles, or a face 
shield.

2.   Warning!

High-pressure injection hazard

Hydraulic fluid is under pressure. In the 
event of a leak, turn off the machine. Do 
not use your bare hands to check for 
leaks. Use a piece of cardboard, wood, or 
plastic to locate the leak. Wear the proper 
hand and eye protection when searching 
for a high-pressure hydraulic leak.

3.   Warning!

Impact and crush hazard

Risk debris falling from the grapple. Do 
not lift any load that cannot be safely 
secured by the grapple. Never allow 
anyone to walk under an overhead load. 
Keep bystanders at a safe distance.

4.   Caution!

Read the Operator's Manual

Read ALL operating instructions and 
safety information in the manual. Learn 
the meaning of ALL safety signs on the 
machine. 

The best safety feature is an informed 
operator.

5.   Caution!

Risk of serious injury or death if 
the engine is on during service or 
maintenance. 

Turn off the engine and remove the key 
before maintenance or service. 

6.  Warning!

reproductive harm

The machine materials 
contain chemicals or 
machine operation may 
produce gases or dust that 
are identified by the state

cancer, birth defects, or 
other reproductive harm.
