to the

AIR POWERED EQUIPMENT

• When operating this equipment, the operator must

wear approved job related safety attire. Eye and hearing
protection must be worn at all times while equipment is
in use as sound levels exceed  dBA. Steel toe safety
shoes should be worn. Head protection is required if work
is performed overhead. Wear proper dust mask based on
material being removed.

• Use the correct size air hose for the tool, ½” diameter

(minimum). Hose and fi ttings must be rated for safe
handling in excess of 100 PSI pressure. The working
pressure of this tool is 80-90 PSI and should never be
allowed to exceed 100 PSI.

• ALR-E Limit the hose length to 30 feet (10 meters) maxi-

mum. Note: The pressure drop of 1/2” diameter hose is
approximately 1 PSI per 90 linear feet.

• ALR-BS Limit the hose length to 30 feet (10 meters)

maximum. Note: The pressure drop of 3/8” diameter hose
is approximately 3 PSI per 90 linear feet.

• A fi lter/water separator must be provided on the air

source to afford an adequate supply of clean, dry air to
this tool. A lubricator should also be used. If a lubricator is
unavailable, lubricate the tool daily by putting 6 to 7 drops
of lightweight machine oil in the hose connector opening
prior to connecting the air supply. In cold weather, use
graphite oil for lubrication.

• Disconnect the air supply before removing

or installing a chisel or accessory . Squeeze

the hand lever to release all compressed air
from the tool. Use only genuine EDCO chisels and acces­sories with this equipment. Failure to do so may result in
serious bodily injury or death.

• Replace any damaged parts immediately. Use only

genuine EDCO parts.

AIR POWERED EQUIPMENT CONTINUED

• To install or remove chisel: Disconnect the air supply.

Squeeze the hand lever to release all compressed air.
Pull back in the spring loaded locking collar and hold while
removing the chisel. Hold back on the spring lodaded lock­ing collar while fi rmly seating the new chisel in the holder .
Release collar to retain the chisel.

• The appropriate accessory must be used for the job at

hand. Do NOT force the tool into the work. The hammer­ing action of the tool will perform the work for you. NEVER
USE THE TOOL AS A PRY BAR. Damage to the equip­ment will result. If the tool does not seem to perform the
work to your specifi cations, try another accessory or call
our customer service department at 1-800-638-3326.

• To activate tool, attach the air source, fi rmly grip the

tool and then squeeze the hand lever on the air valve.

• After releasing the air valve hand lever,
the tool will continue to operate for up to 15
seconds. This is a normal result of stored

up pressure in the tool casing being released gradually.

Be sure to fi rmly grip the tool until ALL air leaves the
chamber.

• Remove the air source from the tool when not in use.

• This equipment will create dust from the

material being removed. That dust may

contain a chemical known to the state of
California to cause cancer and/or birth defects or other
reproductive harm. Check the chemical properties of the
materials to be removed.

• It is the operator’s responsibility to

keep other people (workers, pedestrains,

bystanders, etc.) away during operation.
Block off the work area in all directions with roping, safety
netting, etc. for a safe distance. Failure to do so may result
in others being injured by fl ying debris or exposing them
to harmful dust and noise.

DUST WARNING

Some dust created by power sanding, sawing, 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, and

• Crystalline silica from bricks, concrete and other
masonry products.
Y our risk of exposure to these chemicals varies depending
on how often you do this type of work. To reduce your risk:
work in a well ventilated area, use a dust control system,
such as an industrial-style vacuum, and wear approved
personal safety equipment, such as a dust/particle respira-

tor designed to fi lter out microscopic particles.

EXAMPLE OF WORN AND DAMAGED CHISEL

The above is an example of a chisel that has been abused, probably hitting inserts, studs or other
objects embedded in the working surface. To get maximum life out of a chisel be careful when
working around objects protruding out of the work surface.

EXAMPLE OF AN EVENLY WORN CHISEL

The above is an example of a chisel that has not been abused, as you can see the wear is even

across the width of the chisel. Chisel edge may be renewed by grinding.
