OPERATION

BEFORE YOU START

Know Your Safety Program

• 

Read and understand this manual and the base 

machine manual.

• 

Know the employer’s safety rules. Consult your 

foreman for instructions and safety equipment.

• 

Learn the traffic rules at the work site. Know the hand 

signals used on the job and who is responsible for 

signaling. Take signals from only 

ONE

 person.

• 

Wear personal protection equipment. This includes 

eye protection, hard hat, steel toe shoes, gloves, 

hearing protection and respirator.

Know Your Equipment

• 

Learn and test the function of all controls. If 

malfunctions are found, shut the machine down and 

report the malfunction for repair.

• 

Be familiar with safety devices, indicators, warning 

devices and caution instructions. They will alert you to 

conditions that are hazardous.

• 

Know the clearances in the work area. 

Daily Safety Checks

• 

Ensure all decals are installed and legible. Contact 

LaBounty for replacements as required.

• 

Have a 

DAILY

 safety dialog with all workers. Inform 

them of any abnormal work that is planned. Remind 

them of the safe working distance.

• 

Clear the area. 

ALWAYS

 look out for others. In any 

work area, people constitute a serious safety hazard. 

Before operating, walk around the machine to ensure 

no workers are next to, under or on it. Warn nearby 

workers that you are starting up. 

DO NOT

 start up until 

they are out of danger.

• 

Check the location of cables, gas lines and water 

mains before operation. Ensure work site footing has 

sufficient strength to support the machine. When 

working close to an excavation, position machine with 

the propel motors at the rear. 

• 

Keep bystanders clear, especially before moving the 

boom, swinging the upper structure, or traveling. 

ALWAYS

 be alert for bystanders in or near the 

operating area.

SAFETY DEVICES 

• 

Seat belts

• 

Canopies

• 

Safety decals

• 

Shields and guards

• 

Flags and flares

• 

Barricades

• 

Signs and other 

markings

• 

Warning lights

• 

Falling Objects 

Protective Structures 

(FOPS)

• 

Visual or audible 

warning devices

General Rules For Safe Operation

•  KNOW

 the capacity of the excavator and it’s 

attachments. 

DO NOT

 overload or serious injury 

could result. The attachment may have altered the 

machine’s lift capabilities.

• 

This attachment is for processing materials. 

DO NOT

 

use for unapproved purposes.

• 

DO NOT continuously process oversized materials by 

forcing them into the jaw. This will shorten the life of 

the attachment.

• 

If attachment stalls, scale back the amount of material 

being processed at one time. Overloading can cause 

overheating or damage to the hydraulic system.

• 

Cycle the cylinder completely when processing. 

Fully cycling will allow hydraulic fluid to circulate and 

prevents overheating.

• 

Maintain a safe distance.

•  NEVER

 leave the attachment suspended or pass it 

over people, occupied vehicles or buildings.

• 

When working in confined spaces, keep watch on 

exposed parts, such as cylinder rods and hoses, to 

avoid damage. 

• 

Maintain at least 50 feet (15 meters) between the 

attachment and any nearby power lines. 

•  ALWAYS

 lower the attachment to the ground and 

turn the base machine off when leaving the machine 

unattended. 

•  DO NOT

 close the jaws on a structure and reverse 

the excavator in an attempt to pull down material. This 

is dangerous and will damage the excavator and the 

attachment.

• 

Avoid collision of the boom or jaws, especially when 

working with limited visibility or inside buildings. 

Know the height and reach of the attachment during 

operation, transport and when swinging the excavator.

•  DO NOT

 alter factory preset hydraulics. This may void 

the warranty. 

•  DO NOT

 shear high tensile steel, such as railroad 

rail, spring steel, axles and some types of wire. Jaw 

damage will result. This type of material breaks when 

processed and can become a projectile which could 

cause injury or death.
