a sudden break of the tool bit. Change postures during extended tasks
to help avoid discomfort or fatigue.
• Do not operate a damaged, improperly adjusted, modified or
incompletely assembled tool.
• Use and maintain the tool as stated in this manual. Misuse of the tool
can cause serious injury. Do not modify the tool in any way.
• Do not operate the tool in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Provide adequate ventilation in closed areas when operating a gas or
diesel hydraulic power source.
• Do not inspect, carry, clean, change accessories or perform
maintenance on the tool while the power source is connected.
Accidental engagement of the tool can cause serious injury.
• Ensure work piece is securely fixed. Be aware that failure of the work
piece or accessories may generate high velocity projectiles.
• Stay alert, watch what you are doing and use common sense when
operating a hydraulic tool. Do not operate this tool if you are tired or
under the influence of drugs or alcohol. A moment of inattention while
operating hydraulic tools may result in serious injury.
• During operation, do not contact mechanisms, accessories or hardware
as they can become very hot or sharp; use your Personal Protection
Equipment (PPE).
• Supervising personnel should develop additional precautions relating to
the specific work area and local safety regulations.
• Never operate the tool if you are unsure about the presence of
underground utilities, such as electrical cables, gas pipes, etc. These can
cause a hazard if damaged with the tool.
• The tool is not insulated against coming into contact with electric
power. Use hose certified as non-conductive.
• Do not overreach. Maintain proper footing and balance at all times
when using the tool.
• Slips, trips and falls are major causes of workplace injury. Be observant
of hoses or oil surfaces lying about the work area, as they can be a
tripping hazard.
• Operators must start in a work area without bystanders and must assess
the risks to bystanders.
• Operators must be familiar with all prohibited work areas such as
excessive slopes and dangerous terrain conditions.
• Only use clean hydraulic fluid, filling equipment and lubricants that
have been recommended by STANLEY.
• Ensure tools are working properly and safely by performing preventative
maintenance (PM) procedures.
• Repair and service of this tool must only be performed by an authorized
and certified dealer.
• Do not force the tool to do the work of a larger tool. Use the correct
tool for your application.
• Use only hoses and hose couplings that are rated for a minimum
working pressure of 2500 PSI (172 BAR).
• In spite of the application of relevant safety regulations and the
implementation of safety devices, certain residual risks cannot be
avoided. These risks are: repetitive strain injury due to incorrect posture
and risk of pinching fingers when changing tool bit.
Dust and Fumes
• WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known
to the State of California to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work in
a well ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter out microscopic
particles.
Protect yourself and those around you. Research and understand the
materials you are grinding. Follow correct safety procedures and comply
with all applicable national, state or provisional health and safety
regulations relating to them, including, if appropriate arranging for the
safe disposal of the materials by a qualified person.
• When dust or fumes are created, control them at the point of emission.
Direct tool exhaust to minimize disturbance of dust.
• Operate and maintain the tool as recommended in this manual to
minimize dust.
• Use respiratory protection in accordance with employers instruction or
as required by occupational health and safety regulations.
• Avoid prolonged contact with dust. Allowing dust to get into your
mouth, eyes or lay on the skin may promote absorption of harmful
chemicals.
PPE
• Always wear safety equipment such as impact resistant goggles, ear
protection, head protection, breathing protection and safety shoes at all
times when operating the tool.
• Hands may be exposed to hazards, impacts, cuts, abrasions and heat.
Wear gloves.
• Wear a hardhat if performing overhead work.
• Use PPE that conforms to standards ANSI Z87.1 (Eye and Face
Protection), ANSI Z89.1 (Head Protection), ANSI Z41.1 (Foot Protection)
and ANSI S12.6 (S3.19) (Hearing Protection).
• Do not wear loose fitting clothing or jewelry when operating the tool.

Sound
• Exposure to high noise levels can cause permanent, disabling hearing
loss and other problems, such as tinnitus (ringing, buzzing, whistling
or humming in the ears). Use hearing protection in accordance with
employer’s instructions and as required by occupational health and
safety regulations.
• Use and maintain as recommended in the manual to prevent an
unnecessary increase in noise levels.
Vibration
• When using a non-rotary percussive tool to perform work related
activities, the operator can experience discomfort in the hands, arms,
shoulders, neck or other parts of the body.
• If you experience numbness, tingling, pain or whitening of the skin
in your fingers or hands, stop using the tool. Tell your employer and
consult a physician.
• Wear warm clothing when working in cold conditions and keep your
hands warm and dry.
• Exposure to vibration can cause disabling damage to the nerves and
blood supply of the hands and arms.
• Use and maintain as recommended in the manual to prevent an
unnecessary increase in vibration.
• Check for vibration level before each service. If you feel a higher than
normal vibration, contact your STANLEY dealer for repair.
Hydraulic
• Warning: Hydraulic fluid under pressure could cause skin injection
injury. If you are injured by hydraulic fluid, get medical attention
immediately.
• Do not let hydraulic oil get on the skin. Hydraulic oil is hot. Wear
Personal Protection Equipment (PPE) at all times.
• Do not exceed the maximum relief valve setting stated on the tool.
• Inspect and clean couplers before use, daily. Replace damaged couplers
immediately.
• Hydraulic circuit control valve must be OFF before coupling or
uncoupling tools. Failure to do so may damage the couplers and cause
overheating of the hydraulic system.
• Ensure the couplers are properly connected and are tight.
• Do not operate the tool at fluid temperatures above 140°F (60°C).
Higher temperatures can cause operator discomfort and damage to the
tool.
• Do not exceed the rated flow and pressure as stated on the tool. Rapid
failure of the internal seals may result.
