Other Parts (Not Provided)
You will need the following items and/or accessories to properly set-up and
optimally use your straight die grinder:
• 1/4 inch Plug NPT (M)
o For less stress on your air hose and you, try a flex plug.
• 3/8 inch (ID) Air Hose
• 1/4 inch Coupler NPT (F)
o Eliminate coupler confusion with a universal coupler style.
o Quick-connect couplers quickly, easily join hoses to tools.
o If you don’t use a flex plug, consider a swivel coupler to prevent
hose kinks and reduce stress on your air hose.
• 20 Gallon air compressor or larger
• Grinding stones/attachments with a 1/4 inch shank
• PTFE tape for all fitting connections
• Adjustable wrench for tightening fitting connections
See www.campbellhausfeld.com for additional information on accessories to
support your air tools and pneumatic system.

BEST PRACTICES
u For best output, maintain pressure at the tool of 90 PSI or best output, maintain
pressure at the tool of 90 PSI.
u The longer your air hose the greater the pressure drop from compressor to tool.
If you are using a hose longer than 50 feet, consider upgrading to a 1/2 inch ID air
hose to ensure proper tool pressure.
u Failure to lubricate and maintain your air tools properly will dramatically shorten
their life. Use oil every time you use your air tool to lubricate, clean and inhibit rust
in one step. Campbell Hausfeld sells air tool oil under part number ST1270.

BEST PRACTICES
u The air compressor used with your straight die grinder must be able to maintain
a minimum of 90 PSI when the tool is being used. An inadequate air supply can
cause a loss of power and inconsistent tool output/performance.
u A pressure regulator—used at the tool--is helpful to control the operating pressure
of the tool and maintain 90 PSI.
u Use an oiler to provide oil circulation through the tool and a filter to remove liquid
and solid impurities which can rust or “gum up” internal parts of the tool.
u To disconnect a coupler/plug from a system set-up: push the coupler and plug
together before pulling the coupler sleeve back and separating the coupler and
plug.

LUBRICATION
To protect your tool, lubricate the motor every time--before and after--you
use this tool. You cannot oil the motor too often or put too much oil in the
air inlet.
1. Disconnect the die grinder from air supply.
2. Turn the tool upside down.
3. While pulling the trigger, pour approximately a teaspoon of air tool oil
in the air inlet. Campbell Hausfeld makes an air tool oil under model
number ST1270.
4. Connect the tool to the air supply and cover the exhaust port with a
towel.
5. Run the tool for about 10 seconds. Oil will spray from the exhaust port
when the tool is triggered.
6. Continue to run until no oil is discharged.
7. Wipe all residual oil from tool before use.
OPERATING INSTRUCTIONS
CHANGING ATTACHMENTS
1. Disconnect tool from air supply.
2. To loosen the collet nut to remove an
attachment (or to open the collet nut to
insert an attachment):
a. Hold the spindle stationary with the
spindle wrench (provided); aligning the
flat sides of the spindle with the sides of
the wrench.
b. Align the collet wrench with the flat sides of the collet nut and turn
the collet wrench counter clockwise to loosen the collet nut and
remove the attachment.
3. Insert shank of grinder attachment into collet opening. Make sure shank
is fully inserted.
4. Tighten the collet nut with the wrenches provided:
a. Hold the spindle stationary with the spindle wrench (provided);
aligning the flat sides of the spindle with the sides of the wrench.
b. Align the collet wrench with the flat sides of the collet nut and turn
the collet wrench clockwise to tighten the collet nut and secure the
attachment.
AIR-FLOW/SPEED ADJUSTMENT
The air-flow regulator controls how much air
enters the motor which defines the motor speed/
power. To adjust the amount of air flowing to the
motor, turn the air regulator adjustment screw in
either direction (turns 360 degrees) until desired
flow/motor speed is achieved. To prevent injury,
do not adjust power settings while the tool is
running.

5
STORAGE
Lubricate your die grinder before storing. Follow the air motor lubrication
instructions with an exception to step #5. Only run the die grinder for 2-3
seconds (instead of 10 seconds) because more oil needs to remain in the tool
when storing. Store your tool in a cool dry place.

General Safety
This product is a part of a high pressure system and the following safety
precautions must be followed at all times along with any other existing safety
rules.
1. Read all manuals included with this product carefully. Be thoroughly
familiar with the controls and the proper use of the equipment.
2. Only persons well acquainted with these rules of safe operation should
be allowed to use the air tool.
Do not exceed maximum operating pressure of the
air tool (90 PSI). The air tool could explode and result
in death or serious personal injury.
3. Do not exceed any pressure rating of any component in the system.
Maximum operating pressure of 90 PSI is measured at the tool inlet
while the tool is running. The pressure drop between the compressor
and tool needs to be compensated for at the compressor.
4. Disconnect the air tool from air supply before changing tools or
attachments, servicing and during non-operation.
Safety glasses and ear protection must be worn
during operation.
5. Do not wear loose fitting clothing, scarves, or neck ties. Loose clothing
may become caught in moving parts and result in serious personal injury.
6. Do not wear jewelry when operating any tool. Jewelry may become
caught in moving parts and result in serious personal injury.
7. Do not depress trigger when connecting the air supply hose.
8. Always use attachments designed for use with air powered tools. Do not
use damaged or worn attachments.
9. Never trigger the tool when not applied to a work object. Attachments
must be securely attached. Loose attachments can cause serious injury.
Use of a whip hose prevents accidental triggering of
tool when pressurized air is connected to system.
MANUAL

7
Never carry a tool by the hose or pull hose to move
tool or a compressor. Keep hoses away from heat,
oil and sharp edges. Replace any hose that is damaged, weak or worn.
10. Protect air lines from damage or puncture.
11. Never point an air tool at oneself or any other person. Serious injury
could occur.
12. Check air hoses for weak or worn condition before each use. Make sure
all connections are secure.
Release all pressure from the system before
attempting to install, service, relocate or perform
any maintenance.
Disconnect air tool from air supply before changing
attachments or serious injury could occur.
Make sure attachment stem is fully inserted into
collet opening and collet is securely tightened.
Loose attach-ments could fly off during operation and cause serious injury.
Only use attachments rated for a minimum of 25,000 RPM.
This air tool requires lubrication before initial use
and before and after each additional use.
Disconnect air tool from air supply before
lubricating.
Cover exhaust port with a towel before applying air
pressure. Oil will discharge through exhaust port
during first few seconds of operation after an airtool has been lubricated.
Failure to cover exhaust port can result in serious injury.
13. Keep all nuts, bolts and screws tight and ensure equipment is in safe
working condition.
14. Do not put hands near or under moving parts.
15. Always secure workpiece in a vise or clamp. Do not place hands on the
back cylinder when operating the tool.
16. Do not use a cut-off disc mandrel on this tool unless a safety guard is in
place.
Do not misuse this product. Excessive exposure to
vibration, work in awkward positions, and repetitive
work motions can cause injury to hands and arms. Stop using any tool if
discomfort, numbness, tingling, or pain occur, and consult a physician.
