10 MHP Operating & Maintenance Manual

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.

•  MHP is for processing materials. 

DO NOT

 use for 

unapproved purposes or warranty may be voided.

• 

If MHP stalls during processing, scale back the 

amount of material being processed at one time. 

Overloading can cause overheating and has 

adverse effects on the hydraulic system.

•  Cycle the MHP cylinder completely when 

processing. Fully cycling MHP will allow hydraulic 

fluid to circulate and prevents overheating.

•  Maintain a safe distance.

•  NEVER

 leave MHP 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 15 feet (5 meters) between MHP 

and any nearby power lines. 

•  ALWAYS

 lower MHP 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 MHP attachment.  

•  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.
