Hearing Protection is Recommended
Hearing protection should be usedwhen the noise

level exposure equals or exceeds an 8 hour time-
weighted average sound level of 85dBA. Process
noise, reflective surfaces,other tools being operated

nearby, all add to the noise level in a given work area.
If you are unable to determine your noise level
exposure, we recommend the useof hearing

protection.

Avoid Prolonged Exposure to Vibration
Pneumatic tools can vibrate during use. Prolonged

exposureto vibration orvery repetitive hand and arm
movements, can cause injury. Discontinue the use ot
any tool if you experience tingling, numbness, dis-

comfort or pain in your hands or arms. You should
consultyour physicianbefore resuming useof tool.

90 PSIG Maximum

Thistool isdesigned to operate at an air pressure of
90 pounds per square inch gauge pressure (90 PSIG)

maximum, at the tool. Use of higher air pressure can,

and may cause injury. Also, the use of higher air

pressureplacesthe internal components under loads

and stressesthey were not designed for, causing
premature toolfailure.

NOTE: THE AIR SUPPLY SHOULD BE CLEAN AND
DRY, PREFERABLY LUBRICATED. FOR BEST
RESULTS DRAIN THE MOISTURE FROM YOUR

COMPRESSOR DAILY,

Hammer features a 4 bolt back head design to
eliminate handle loosening and breakage. The

variable speed trigger provides easy start-up and
better control while the heat treated barrel and

retainer provide maximum durability and long
service life.

Features

• Four bolt backhead design

• Adjustableexhaustdeflector

• 3/8"-24 inlet bushing

The Craftsman Model 875,190280 chipping

hammer isdesignedto operate on 90 PSIG.Lower
pressure(below 90 PSIG)will reduceperformance

of the tool, while higher air pressure(over 90 PSIG)
raisesthe performance of the tool beyond its rated
capacityand could causeseriousdamage to tool

and user.

Always useclean dry air. Excessivemoisture and dirt
will greatly reduce the life of any air motor. We

recommend the installation of an in-line
filter-regulator-lubricator as closeto the tool as
possible.

A 1/2" air hose isrequired ensure the tool has the
necessary air supply. Be sure all hoses and fittings
are the correct size and tightly secured.

WARNING:

Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains

chemicals known to cause cancer, birth defects or
reproductive harm. Some examples of these chemicals
are:

Lead from lead-based paints
Crystalline silica from bricks, cement arid other
masonry products

Arsenic and chromium from chemically treated
lumber

Your risk from these exposures vades, 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.

WARNING: Disconnecttoolfromair supplybefore
servicingor changing chisels.

To Install Chisel:

Designedfor use with oval .680 round shank collar
chisels.

Remove retainer spring (red. # 2t) from retainer (ref. #

20). Slide retainer (ref. # 20) off the cylinder (ref. # 16).

Insertchisel throughretainer (ref. # 20) oval hole.Turn a

Before the toolis aonnected to the air supply,clearthe air
hose of accumulateddust and moisture and add several

dropsof air toolell.

2. Remove retainer (ref. # 20) with chisel.

Lubrication

An automatic in-linefllter-regu|ator-lubdcatoris recom-

mended as it in.eases tool life and keeps the tool in
sustained operation,The in-line lubricator should be

chedr.edregularlyand filled withair tool oil.Proper
adjuaimenlof the in-linelubricatoris performed by
placinga sheet of paper next to the exhaust portsand
holdingthe throttleopen approximately30 seconds.The
lubricatoris properlyset when a lightstainof oll collects

on the paper. Excessive amountsof oil shouldbe
avoided.

In the event that it becomes necessaryto store the toolfor
an extended periodof time (overnight,weekend, etc.), it

shouldreceive a generous amountof lubricationat that
time.The toolshould be run for approximately30 sec-

onds to ensure oil has been evenly distributedthroughout
the tool. The tool should be stored in a dean and dry

environment.

Recommended lubricants: Use airtool oilor any other
high grade turbine oil containingmoisture absorbent, rust
inhibltom,metal wetting agents and an EP (extreme

pressure) additive.
