1. Read and understand this entire manual
before attempting assembly or operation.
2. Read and understand all warnings posted on
the tool and in this manual. Failure to comply
with all of these warnings may cause serious
injury.
3. Replace warning labels if they become
obscured or removed.
4. Do not use this tool for other than its intended
use. If used for other purposes, JET disclaims
any real or implied warranty and holds itself
harmless from any injury that may result from
that use.
5. Always wear approved safety glasses or face
shield while using this tool. (Everyday
eyeglasses only have impact resistant lenses;
they are not safety glasses.)
6. Wear ear protectors (plugs or muffs) if the
noise exceeds safe levels.
7. Wear gloves and protective clothing if
operation produces sparks or flying particles.
Gloves should be tight-fitting, without frayed
fingers or hanging threads. Keep hands and
body away from the working area of tool.
8. Do not operate an air tool continually at full
throttle without a work load on the tool.
9. The air tool must be properly lubricated before
operating.
10. Never start a percussion type air tool (chipper,
breaker, buster, etc.) without securing the
tooling in the retainer and placing the tip
against the work surface.
11. Do not operate air tool without its guards in
place. Do not modify the tool.
12. Do not operate this tool while tired or under
the influence of drugs, alcohol, or any
medication.
13. Adopt a comfortable posture with proper
balance, and maintain secure footing at all
times. Non-slip footwear or anti-skid floor
strips are recommended.
14. Do not wear loose clothing or jewelry. Confine
long hair.
15. Excessive air pressure and too much free
rotation may decrease life of the tool and may
cause a hazardous situation.
16. Check air hoses for wear, and keep them
away from heat and sharp edges. Repair or
replace damaged air hose immediately. Do
not carry tool by the air hose.

24. Keep visitors a safe distance from the work
area. Keep children away.
25. Give your work undivided attention. Looking
around, carrying on a conversation and
“horse-play” are careless acts that can result
in serious injury.
26. Do not force a tool or attachment to do a job
for which it was not designed. The right tool
will do the job better and more safely.
27. Repetitive motions and/or exposure to
constant vibration can be harmful to hands
and arms. Take frequent breaks and relax
hands during extended operation. Change
posture to avoid discomfort or fatigue.

toward sensitive areas of the body, and may
propel small particles caught in the air stream.
Exercise proper caution.
29. Use only recommended accessories;
improper accessories may be hazardous.
30. Maintain tools with care. Keep air tool clean
and oiled for best and safest performance.
31. Do not use combustible gases, carbon
dioxide, oxygen or any bottled gas as an air
source for the tool. These can present risk of
explosion and serious injury.
32. Do not lubricate the tool with combustible
liquids, such as kerosene, diesel or jet fuel.
33. Do not dispose of this tool with normal
household waste. Never dispose of the air tool
into fire.
