2.4.1  Equipment Safety Guidelines

A few seconds of thought and a careful approach to handling 
equipment can prevent accidents.

• 

Replace safety or instruction signs (decals) that are not 
readable or missing. For locations and explanations, see 

Safety Signs on page 12

.

• 

Do not modify the equipment in any way. Unauthorized 
modifications may affect the integrity of the machine 
or the ability of the machine to perform as designed. 
Modifications can impair safety or function. They can affect 
the life of the equipment and void the warranty. 

• 

Make sure the machine is correctly stationed, adjusted, and 
in good operating condition.

• 

Never exceed the limitations of the machine. If its ability to 
do the job, or to do it safely is in question–

STOP!

• 

Protective cab shields must be provided on a log loader 
unless the absence of shields does not pose a hazard to the 
operator.

2.4.2  Safe Condition

References are made to 

safe condition

 throughout this manual. 

Safe condition means putting the machine in a state that makes 
it safe to service or maintain.

Before starting any service or maintenance, complete the 
following:

SAFE CONDITION

1. 

Remove material from the grapple.

2. 

Lower the grapple to ground.

3. 

Turn off the excavator engine.

4. 

Engage the hydraulic control lockout device.

5. 

Turn off the main hydraulic switch.

6. 

Move the hydraulic controls to make sure that there is no 
movement.

2.5  Create a Safe Work Site

For more information, see 

Fig. 2 on page 10

.

2.5.1  Designated Safe Area

Safe Area

 must be designated for workers who are on foot 

and in close proximity to the equipment.

• 

The boundaries of a designated Safe Area must be 
communicated to all workers within and in close proximity 
to the Work Zone.

• 

No equipment should enter into or proceed through a Safe 
Area unless—

  

-

The equipment operator first obtains permission in a 
clear and unmistakable manner from all of the workers 
in that safe work area or from the supervisor of those 
workers, and

  

-

Those workers take a safe position.

2.5.2  Work Zone Arrangement

• 

Work Zone

 includes any area where work with this 

grapple is done, but does not include the traveled portion 
of a road unless that portion of the road is being used as a 
landing.

• 

Work being done in a Work Zone in a forestry operation 
must be planned and the work area must be located, 
constructed, maintained, and operated to ensure that:

  

-

Logs can be moved safely in the area.

  

-

Log piles and equipment used to handle the logs do not 
become unstable or otherwise create a hazard.

  

-

Workers are able to work in locations clear of moving 
logs and equipment.

  

-

Workers are not exposed to incoming or runaway logs 
or other debris.

  

-

The area is kept free from buildup of bark and other 
debris to the extent that it would pose a risk to workers.

  

-

An effective method of dust control is used and 
maintained.

• 

Log piles must, to the extent practicable, be located on 
stable and relatively level ground.

• 

Log piles must not be higher than the safe operating reach 
of the excavator being used to handle the logs.
