SAFETY PRECAUTIONS
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. Review them carefully before operating the machine and
before performing general maintenance or routine service.
Supervising personnel should develop additional pre-
cautions relating to the specic 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 manual, 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 injury, or death.
• Operate the machine in a work area WITHOUT BYSTANDERS. 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 conned areas
where there may be a risk of crushing the operator
between the machine and another object.
• DO NOT OPERATE THE TRACHORSE IN ENCLOSED 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 hydraulic 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 present.
• 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 ensure 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 hydraulic tools.
• DO NOT inspect or clean the machine while the engine is running. Accidental engagement of the machine 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 overheating of the hydraulic system.
• Before operating hydraulic tools, read and understand the operation manual furnished with the tool.
• DO NOT operate a damaged, or improperly adjusted, 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 welding or acetylene cutting of the equipment.
• Prevent possible personal injury or equipment damage 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 design capacity.
• Always keep critical markings, such as labels and
warning stickers legible.
• Always replace parts with replacement parts recommended 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
• Always be well-rested and mentally alert when operating 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 connections are tight.
• Be sure all hoses are correct for current ow direction to and from the tool being used.
• DO NOT inspect hoses and ttings for leaks by using 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 components. Electrocution or burns could result from
improper contact.

HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
Stanley Hydraulic Tools. They are:
Certied non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certied 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 certied or labeled non-conductive) — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certied 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
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 PROPERLY 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 FITTING 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.
DO NOT REMOVE THIS TAG

3. DO NOT EXCEED HOSE WORKING PRESSURE OR ABUSE HOSE. IMPROPER USE
OR HANDLING OF HOSE COULD RESULT IN BURST OR OTHER HOSE FAILURE.
KEEP HOSE AS FAR AWAY AS POSSIBLE FROM BODY AND DO NOT PERMIT DIRECT
CONTACT DURING USE. CONTACT AT THE BURST CAN CAUSE BODILY INJECTION
AND SEVERE PERSONAL INJURY.
4. HANDLE AND ROUTE HOSE CAREFULLY TO AVOID KINKING, ABRASION, CUTTING, OR
CONTACT WITH HIGH TEMPERATURE SURFACES. DO NOT USE IF KINKED. DO NOT
USE HOSE TO PULL OR LIFT TOOLS, POWER UNITS, ETC.
5. CHECK ENTIRE HOSE FOR CUTS CRACKS LEAKS ABRASIONS, BULGES, OR DAM-
AGE TO COUPLINGS IF ANY OF THESE CONDITIONS EXIST, REPLACE THE HOSE
IMMEDIATELY. NEVER USE TAPE OR ANY DEVICE TO ATTEMPT TO MEND THE HOSE.

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
specications as set forth by SAE J517.
