this product in accordance with all applicable
standards and regulations (local, state, country,
federal, etc.).
Compressed air models always use clean, dry
air at 90 psi (6.2bar/620kPa) maximum air
pressure at the inlet. Higher pressure may
result in hazardous situations including
excessive speed, rupture, or incorrect output
torque or force.
Electric models must always utilize proper
gauge, and rated electrical cords with correct
connections.
Be sure all hoses and fittings are the correctly
sized and secured.
Ensure an accessible emergency shut off has
been installed in the air or electrical supply line.
Make others aware of its location.

Always use Personal Protective Equipment
appropriate to the tool used and material
worked. This may include dust mask or other
breathing apparatus, safety glasses, ear plugs,
gloves, apron, safety shoes, hard hat and other
equipment,
Prevent exposure and breathing of harmful dust
and particles created by power tool use:
- Some dust created by power sanding, sawing,
and grinding, drilling, and other construction
activities contains chemicals known 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.
Keep others a safe distance from your work area,
or ensure they use appropriate Personal
Protective Equipment.
This tool is not designed for working in explosive
environments, including those caused by fumes
and dust, or near flammable materials.
Electrically powered tools are not insulated
against electric shock.
NOTICE
WARNING

Be aware of buried, hidden or other hazards in
your work environment. Do not contact or
damage cords, conduits, pipes, or hoses that
may contain electrical wires, explosive gases or
harmful liquids.

SECTION II
BEFORE USE
Place three drops of oil into the air inlet using light machine oil. (See recommended lubrications.)
The compressed air should be free from moisture and contamination. The installation of a filter/regulator/lubricant air preparation
set with a moisture trap is strongly recommended
Ensure that only 3/8” (10mm) bore airline is used and that all couplings are tight and in good condition.
Limit the length of airline to 50ft. Where extra length is necessary, for each additional 50ft of airline, the pressure drop is
approximately 4psi at 100 psi (0.2bar at 6.9bar).
NOTE: The correct operating pressure is 6.2bar (90psi).
CLEANING
At intervals of no more than 50 hours of operation, operating becomes sluggish or if the tool begins to show signs of sticking, flush through
with a paraffin/high flash solvent. Immediately after flushing, thoroughly oil the tool with one of the recommended lubricants.
NOTE: If the tool is used on concrete scabbling applications where highly abrasive airborne particles are present, we strongly
recommend that this practice is carried out at least on a daily basis.
