SAFETY SYMBOLS

MHP3 User Manual 5

Tool operators and maintenance personnel must always

comply with the safety precautions given in this manual

and on the stickers and tags attached to the machine.

These safety precautions are given for your safety. Re-

view them carefully before operating the machine and

before performing general maintenance or routine ser-

vice.

Supervising personnel should develop additional pre-

cautions relating to the specic work area and local

safety regulations. If so, place the added precautions in

the space provided in this manual.

If you have not read this manual or the engine manu-

al, you are not ready to operate the MHP3. Read and

understand this manual and any stickers and tags

attached to the machine before operation. Failure to

do so can result in equipment damage, personal in-

jury, or death.

• Operate the machine in a work area WITHOUT BY-

STANDERS. The operator must be familiar with all

prohibited work areas such as excessive slopes and

dangerous terrain conditions.

• DO NOT operate the machine ACROSS excessive

slopes or unstable terrain where “tip over” is a hazard.

• DO NOT operate the machine in conned areas

where there may be a risk of crushing the operator

between the machine and another object.

• DO NOT OPERATE THE TRACHORSE IN EN-

CLOSED SPACES. Inhalation of engine exhaust

can be fatal.

• DO NOT WEAR LOOSE CLOTHING that can get

entangled in the working parts of the machine or hy-

draulic tools.

• DO NOT add fuel to the machine while it is running

or still hot.

• DO NOT operate the machine if a fuel odor is pres-

ent.

• DO NOT operate the machine within 3.3 ft./1 m of

buildings, obstructions, or ammable objects.

• Allow the engine to cool before storing the machine

in an enclosure.

• DO NOT RIDE ON, OR ALLOW ANYONE ELSE TO

RIDE ON, THE MACHINE AT ANY TIME.

• Establish a training program for all operators to en-

sure safe operation.

• DO NOT operate the machine unless thoroughly

trained or under the supervision of an instructor.

• Always wear safety equipment such as goggles,

ear, head protection, respiratory and safety shoes

at all times when operating the TracHorse and hy-

draulic tools.

• DO NOT inspect or clean the machine while the en-

gine is running. Accidental engagement of the ma-

chine can cause serious injury or death.

• Wear a homologated respirator when cutting or

breaking masonry, concrete, asbestos and other

materials that produce dust.

• The hydraulic circuit control switch must be in the

“OFF”position when coupling or uncoupling hydrau-

lic tools. Wipe all couplers clean before connecting.

Use only lint-free cloths. Failure to do so may result

in damage to the quick couplers and cause over-

heating of the hydraulic system.

• Before operating hydraulic tools, read and under-

stand the operation manual furnished with the tool.

• DO NOT operate a damaged, or improperly adjust-

ed, machine. DO NOT operate with guards removed.

• DO NOT weld or cut with an acetylene torch any

surface or component of the equipment. Consult

with the Stanley factory before performing any weld-

ing or acetylene cutting of the equipment.

• Prevent possible personal injury or equipment dam-

age by having all repair, maintenance and service

performed only by authorized and properly trained

personnel.

• DO NOT exceed the rated limits of the equipment

or use the equipment for applications beyond its de-

sign capacity.

• Always keep critical markings, such as labels and

warning stickers legible.

• Always replace parts with replacement parts recom-

mended by Stanley Hydraulic Tools.

• Keep all body parts away from working parts of the

TracHorse.

• Be aware of surrounding hazards. Noise created by

the TracHorse and the tools it operates may mask

early indications of approaching hazards.

• Only use the TracHorse in well-ventilated areas. DO

NOT operate in explosive atmospheres, in closed

environments or near ammable substances.

SAFETY PRECAUTIONS

6 MHP3 Manual

• Always be well-rested and mentally alert when op-

erating the TracHorse and tools. DO NOT operate if

affected by medications, drugs or alcohol.

• Keep clear of hot (engine) parts and exhaust.

• DO NOT use ammable solvents around the engine.

• DO NOT reverse tool rotation by changing uid ow

direction.

• Always use hose and ttings rated for 2500 psi/172

bar with a 4 to 1 safety factor. Be sure all hose con-

nections are tight.

• Be sure all hoses are correct for current ow direc-

tion to and from the tool being used.

• DO NOT inspect hoses and ttings for leaks by us-

ing bare hands. “Pin-hole” leaks can penetrate the

skin.

• DO NOT operate tools if oil temperature exceeds

140 °F/60 °C. Operation at high temperatures can

cause higher than normal temperatures at the tools

which can result in operator discomfort.

• Disconnect battery before servicing electrical com-

ponents. Electrocution or burns could result from

improper contact.

• When using pressure cleaning equipment, do not

aim the jet directly at electrical components. Make

sure these components are covered or protected.

Do not place the water jet directly in the air lter,

exhaust or air intake ports of the engine.

The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-

draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with

Stanley Hydraulic Tools. They are:

Certied non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid

reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certied non-

conductive is the only hose authorized for use near electrical conductors.

Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforce-

ment, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near

electrical conductors.

Fabric-braided (not certied or labeled non-conductive) — constructed of thermoplastic or synthetic rubber in-

ner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This

hose is not certied non-conductive and must never be used near electrical conductors.

HOSE SAFETY TAGS

To help ensure your safety, the following DANGER tags are attached to all hose purchased from Stanley Hydraulic

Tools. DO NOT REMOVE THESE TAGS.

If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be

obtained from your Stanley Distributor.

THE TAG SHOWN BELOW IS ATTACHED TO “CERTIFIED NON-CONDUCTIVE” HOSE

THE TAG SHOWN BELOW IS ATTACHED TO “CONDUCTIVE” HOSE.

DANGER

1. FAILURE TO USE HYDRAULIC HOSE LABELED AND CERTIFIED AS NON-CONDUCTIVE

WHEN USING HYDRAULIC TOOLS ON OR NEAR ELECTRIC LINES MAY RESULT IN

DEATH OR SERIOUS INJURY.

FOR PROPER AND SAFE OPERATION MAKE SURE THAT YOU HAVE BEEN PROP-

ERLY TRAINED IN CORRECT PROCEDURES REQUIRED FOR WORK ON OR AROUND

ELECTRIC LINES.

2. BEFORE USING HYDRAULIC HOSE LABELED AND CERTIFIED AS NON-CONDUCTIVE

ON OR NEAR ELECTRIC LINES. WIPE THE ENTIRE LENGTH OF THE HOSE AND FIT-

TING WITH A CLEAN DRY ABSORBENT CLOTH TO REMOVE DIRT AND MOISTURE AND

TEST HOSE FOR MAXIMUM ALLOWABLE CURRENT LEAKAGE IN ACCORDANCE WITH

SAFETY DEPARTMENT INSTRUCTIONS.

Recommendations

The chart to the right shows recommended

minimum hose diameters for various hose

lengths based on gallons per minute (gpm)/

liters per minute (lpm). These recommenda-

tions are intended to keep return line pressure

(back pressure) to a minimum acceptable lev-

el to ensure maximum tool performance.

This chart is intended to be used for hydraulic

tool applications only based on Stanley Hy-

draulic Tools tool operating requirements and

should not be used for any other applications.

All hydraulic hose must have at least a rated

minimum working pressure equal to the maxi-

mum hydraulic system relief valve setting.

All hydraulic hose must meet or exceed

specications as set forth by SAE J517.
