2.4  Safety Rules

 CAUTION!

Hearing loss hazard. Prolonged 

exposure to loud noise may cause 

permanent hearing loss. Use suitable 

protection while operating the 

machine.

W016

Safety is a primary concern in the design and manufacture of 
Wallenstein products. Unfortunately, efforts to provide safe 
equipment can be wiped out by a single careless act.

For safety information that is specific to machine operation, 
service, or maintenance, see the applicable section in this 
manual.

• 

It is the operator's responsibility to read, 
understand, and follow ALL safety and 
operating instructions in this manual.

• 

If you do not understand any part of this 
manual or require assistance, contact your 
local dealer, the distributor, or Wallenstein 
Equipment. 

• 

The operator of this grapple must be a responsible, properly 
trained and physically-able person familiar with machinery 
and trained in the operation of an excavator. Learn the 
controls and how to stop the machine quickly in an 
emergency before working with the grapple.

• 

An employer has the responsibility to train employees how 
to operate the equipment they are using. When someone 
does not understand the basic operation of a piece of 
equipment, they can create dangerous situations very 
quickly. Operators must completely understand the safety 
information in this manual and the safety decals on the 
machine.

• 

If the machine is loaned or rented, it is the owner's 
responsibility to make sure that, before using the machine, 
every operator:

  

-

Reads and understands this manual.

  

-

Is instructed in the safe and correct use of the machine 
and related equipment.

  

-

Understands and knows how to set the machine to a 

Safe Condition

. For instructions, see 

Safe Condition on 

page 9

.

• 

Review safety related items annually with all personnel who 
will be operating or performing maintenance.

• 

Keep a first-aid kit available for use, 
should the need arise, and know how to 
use the contents. 

• 

Keep a fire extinguisher available for use, 
should the need arise, and know how to 
use it.

• 

Never consume alcohol or drugs before or during machine 
operation. Alertness or coordination can be affected. 
Consult your doctor about operating this machine while 
taking prescription medications.

• 

Stay a minimum 20 ft (6 m) away from power lines. Power 
lines as well as the surrounding air space which insulates 
the line can be hazardous. Electricity can arc or jump 
through the insulating air space. The higher the voltage, the 
more likely it is for an arc to occur.

• 

Never swing a load if the operator's line of sight is 
obstructed. Do not lift it higher than is necessary to provide 
unobstructed vision for the equipment operator.

• 

Wear the appropriate PPE when operating, servicing, or 
maintaining the machine. 
This includes, but is not limited to:

  

-

A hard hat.

  

-

Heavy gloves.

  

-

Hearing protection.

  

-

Protective shoes with steel toes and slip resistant soles.

  

-

Protective glasses, goggles, or a face shield.

• 

Avoid wearing loose fitting clothing, loose or uncovered 
long hair, jewelry, and loose personal articles. These can 
get caught in moving parts and cause injury. Jewelry may 
also ground a live electrical circuit causing injury and 
machine damage.

• 

Prolonged exposure to loud noise may 
cause permanent hearing loss. Power 
equipment with or without a vehicle 
attached can often be noisy enough to 
cause permanent, partial hearing loss. 

• 

Wear hearing protection on a full-time basis if the noise in 
the operator's cab exceeds 80 dB. Noise over 85 dB on a 
long-term basis can cause severe hearing loss. Noise over 
90 dB adjacent to the operator over a long-term basis may 
cause permanent, total hearing loss. 

• 

Keep bystanders at least 10 ft (3 m) from the stacking 
zone. Mark the zone with safety cones.

• 

Never allow anyone to ride on the machine.

• 

Use the machine only in daylight or good artificial light.

• 

Before starting work, complete the tasks described in the 

Pre-start Checklist on page 25

.

• 

Do not risk injury or death by ignoring good safety 
practices.
