For Your Own Safety Read Instruction Manual
Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazard-
ous conditions. This manual uses a series of symbols and signal words which
are intended to convey the level of importance of the safety messages. The
progression of symbols is described below. Remember that safety messages by
themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.
Indicates an imminent hazardous situation which, if
not avoided, WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, MAY result in minor or moderate injury.
It may also be used to alert against unsafe practices.
This symbol is used to alert the user to useful infor-
mation about proper operation of the equipment.

air line connection inspection.
An air line that becomes disconnected
from a tool can whip violently, causing
severe injury. Verify that air line is
properly connected and the fittings are
tight and leak free. Leaking fittings can
indicate the fitting is cracked and is
about to fail.

changing bits. When swapping grinding
bits, disconnect the grinder from air to
prevent an accidental start-up injury.
no list of safety guidelines can be
complete. every shop environment
is different. always consider safety
first, as it applies to your individual
working conditions. use this and
other tools with caution and respect.
failure to do so could result in
serious personal injury, damage to
equipment or poor work results.
tool stability. to establish the best
control possible when grinding, hold the
grinder with two hands, and stabilize your
hands and body against a fixed object.
Free-grinding (using one hand and no
support) can allow the tooling to grab the
workpiece and cause you to lose your grip
on the grinder, leading to severe injury.

section 2: setup
unpacking
assembly
your tool was carefully packaged for safe
transportation. remove the packaging
materials from around your tool and inspect
it. if you discover the tool is damaged,
please immediately call Customer Service
at (570) 546-9663 for advice.
to assemble the grinder:
1. remove the plastic plug from the
grinder air inlet.
2. Apply pipe sealant on the quick
disconnect fitting threads, and install
the fitting into the grinder air inlet.
save the containers and all packing
materials for possible inspection by the
carrier or its agent. otherwise, filing a
freight claim can be difficult. When you are
completely satisfied with the condition of
your shipment, inventory the contents.
3. insert the shank of the desired grinding
bit into the collet until it bottoms, and
tighten the collet nut (see figure 1)
using the spindle and collet wrenches.
4. release the trigger lock, depress the
trigger, place a few drops of air tool
oil into the air inlet, and release the
trigger. the grinder is ready for use.
if any non-proprietary parts are missing
(e.g., a nut or a washer), we will gladly
replace them; or for the sake of expediency,
replacements can be obtained at your
local hardware store.
air supply setup tips:
•
if the air hose is longer than 25-feet,
increase the air pressure to 100 psi to
compensate for air flow restriction.
inventory
•
•
For consistent air flow, use air hoses
with an inside diameter of 3⁄8" or larger.

daily maintenance
before and after each use:
lubrication
•
Check for leaking or cracked air fittings;
bubbled, cut, or worn hoses; and
replace as required.
in most cases for periodic tool use, manual
lubrication is sufficient. however, if the tool
is to be used on a consistent basis, we
recommend installing an automatic oiler to
eliminate dry runs and ensure maximum
tool life. the two methods are explained
below.
•
•
place a few drops of air tool oil (not
motor oil) in the air inlet fitting.
drain the air supply compressor
tank and the water filter separator
reservoirs.
Manual Lubrication: every two hours of
use, place a few drops of air tool oil in
the air inlet fitting and at all pivot points.
do not use motor oil as the additives can
corrode the tool seals. next, connect the
tool to the air line and cover the exhaust
port (see figure 1, on page 5) with a rag.
position the end of the tool safely away
from you, and run the tool for 30 seconds
to completely circulate the oil through the
tool and into the rag.
•
Make sure the trigger lock is operational
and that the collet holds the tooling
tightly. Verify that the collet nut and
insert are free of cracks and wear.
periodically as required:
•
•
•
remove the quick disconnect fitting
and clean the filter screen. see figure
1 on page 5 for location.
Automatic Lubrication: Adjust the
automatic in-line oiler. place a sheet of
paper next to the exhaust port, run the tool
at three or four 30-second intervals. When
finished, the paper should show a slight oil
stain. if no oil is seen or excessive oil drips
from the paper, adjust the oiler and repeat
this process until the adjustment is correct.
see figure 3 for location.
Wipe the grinder housing and the
shanks of the tool bits with a lightly
oiled cloth.
Check and adjust the automatic in-line
oiler.
