Save all warnings and instructions
for future reference.
1. PRIOR TO USING THIS PRODUCT, READ
AND UNDERSTAND ALL INSTRUCTIONS AND
SAFETY PRECAUTIONS AS OUTLINED IN
THE MANUFACTURER’S MANUAL OF THE
BREAKER HAMMER THAT IS TO BE USED.
2. BOLT THE BREAKER HAMMER SECURELY TO
THE CLAMPING BLOCKS ON THE BREAKER
HAMMER TROLLEY AND TEST WORK
SET-UP FOR STABILITY BEFORE USE.
3. UNPLUG THE BREAKER HAMMER FROM ITS
ELECTRICAL SUPPLY BEFORE PERFORMING
ANY SERVICE OR MAINTENANCE ON
THE TROLLEY. Make sure to unplug the
breaker hammer before leaving the work
area, moving the Trolley from one location to
another, cleaning debris from the unit, etc.
4. This product is not a toy.
Do not allow children to play with or near this item.
5. Use as intended only.
6. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
Work Area Safety
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate power tools 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.
3. Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose control.
Assembly Precautions
1. Assemble only according to these instructions.
Improper assembly can create hazards.
2. Wear ANSI-approved safety goggles and
heavy-duty work gloves during assembly.
3. Keep assembly area clean and well lit.
4. Keep bystanders out of the area during assembly.
5. Do not assemble when tired or when under the
influence of alcohol, drugs or medication.
6. Weight capacity and other product capabilities apply
to properly and completely assembled product only.
Personal safety
1. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication. A moment of inattention while operating
power tools may result in serious personal injury.
2. Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools
with your finger on the switch or energizing power
tools that have the switch on invites accidents.
4. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
5. Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry
or long hair can be caught in moving parts.
6. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
7. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI-approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work area.

Percussion Hammer Safety Warnings
1. Wear ear protectors. Exposure to
noise can cause hearing loss.
2. Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
3. Keep clear of moving parts.
4. Unplug before inspecting, removing or
installing bit, or performing any service.
5. Pull on bit after installation and before use;
bit may move but MUST NOT slide out.
6. Wear steel-toed boots during use.
7. Do not operate this tool if you have back, neck,
or wrist injuries, or other conditions that will
be aggravated by the severe jerking forces
that this tool exerts upon the operator.
8. Avoid unintentional starting. Prepare to
begin work before turning on the tool.
9. Do not leave the tool unattended when it is plugged
into an electrical outlet. Turn off the tool, and
unplug it from its electrical outlet before leaving.
10. This product is not a toy. Keep it
out of reach of children.
11. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
In addition, people with pacemakers should:
• Avoid operating alone.
• Properly maintain and inspect to avoid electrical shock.
• Properly ground power cord. Ground Fault Circuit
Interrupter (GFCI) should also be implemented
– it prevents sustained electrical shock.
12. The warnings, precautions, and instructions
discussed in this instruction manual cannot cover all
possible conditions and situations that may occur.
It must be understood by the operator that
common sense and caution are factors
which cannot be built into this product,
but must be supplied by the operator.
Vibration Safety
This tool vibrates during use. Repeated or long-term
exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups
to ensure medical problems are not being caused
or worsened from use. Pregnant women or
people who have impaired blood circulation to
the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

Work Area Set Up
1. Make sure the work area is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
3. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
If working in the ground or on a concrete slab
on the earth, call local utility company to
ensure that area is clear of utility lines.
4. Keep power cord away from moving machines.
General Operation
TO PREVENT SERIOUS INJURY:
Wear ANSI-approved safety goggles, ear
protection, steel-toe boots, dust mask and
heavy-duty work gloves during use. Keep
feet clear of breaker hammer. Keep children
and animals well clear of the work area.
TO PREVENT SERIOUS INJURY:
Read the breaker hammer manufacturer’s
instruction manual before use. Ensure that
the breaker hammer is firmly secured to the
Trolley. Use with a breaker hammer only – do
not use with any other type of power tool.
1. Check scraper for dullness, cracks, or other damage.
CAUTION! TO PREVENT INJURY: A dull scraper can
cause unnecessary scraper movement, resulting in tool
wear and possible injury. Use only sharp floor scraper.
2. Secure breaker hammer power cord to hook on
end of either handle grip, and hook and loop
fasteners, to keep cord clear of scraper blade and
protect it from crushing, abrasion, and scraping
by broken tile or other flooring materials.

materials or to increase demolition speed.
NOTICE: Running tool with no load or “empty
blows” will damage the breaker hammer.
7. When work is complete, turn off power switch.
8. To prevent accidents, turn off the tool and
disconnect its power supply after use.
