1.1 Safety
This symbol calls your attention to instructions concerning your personal safety. Be sure
to observe and follow these instructions. This symbol accompanies a signal word. The
word DANGER indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury. WARNING suggests a potentially hazardous situation
which, if not avoided, could result in death or serious injury. CAUTION refers to potentially
hazardous situations which, if not avoided, may result in minor or moderate injury to per-
sons or equipment. Read all safety instructions before operating this equipment and
observe all safety warnings!
Warning stripes are placed on areas where a single decal would be insufficient. To avoid
serious injury, keep out of the path of any equipment marked with warning stripes.
Read and observe all safety instructions before operating this equipment! Also read any
additional manufacturer’s manuals and observe any applicable safety instructions includ-
ing dangers, warnings, and cautions.
Always be sure that all safety decals are clean and readable. Replace all damaged safety
decals to prevent personal injury or damage to the equipment. Contact your local distribu-
tor, or call your Customer Service Representative to order more decals.
IMPORTANT! Always properly dispose of all by-products,
including debris, coolant, oil, and filters.
DANGER! For the user’s safety, the power cord on this
product has a grounded plug. This power cord should only
be used with correctly grounded (3-hose) receptacles to
avoid electrical shock. To prevent electrical shock hazard,
this unit must be connected to a GFI (Ground Fault Inter-
rupter). The National Electrical Code, Article 680-41(A),
requires a GFI be installed in the branch circuit supplying
fountain equipment rated above 15 volts. See your local
electrical supply dealer for various brands of GFI’s.
DANGER! Make sure all guards and covers are in place
and secured before operating the sharpener. Failure to do
so may result in serious injury.

area when coiling, carrying or changing a blade. Failure to
do so may result in serious injury.
WARNING! Always wear eye protection when operating the
sharpener. Failure to do so may result in serious injury.
WARNING! Only operate this machine in a well-ventilated
area. Mist from the grinding coolant can be hazardous,
especially if operating multiple grinders in an enclosed
space. See the coolant MSDS sheet for more information.
WARNING! NEVER dress the wear area of the grinding
wheel by using the dressing stone on the side surface of
the wheel. Doing so could cause the wheel to explode,
resulting in personal injury and/or machine damage.
WARNING! Always check the grinding wheel for cracks or
chips before using it. NEVER use a cracked or chipped
wheel. Doing so may result in severe personal injury and/or
machine damage.
CAUTION! Remove the grinding wheel while transporting
the Sharpener to prevent cracking or damage due to jarring
or bumping of the unit.

2.2 Pump Installation
DANGER! For the user's safety, the power cord on this
product has a grounded plug. This power cord should only
be used with correctly grounded (3-hole) receptacles to
avoid electrical shock. To prevent electrical shock hazard,
this unit must be connected to a GFI (Ground Fault Inter-
rupter). The National Electrical Code, Article 680-41(A),
requires a GFI be installed in the branch circuit supplying
fountain equipment rated above 15 volts. See your local
electrical supply dealer for various brands of GFI's.
CAUTION! Do not run the pump until it is under water. Dry
operation will damage the pump!
CAUTION! Use the 110 Volt AC output to power the coolant
pump of the Wood-Mizer Automatic Sharpener Attachment
only. Using the output for other purposes will result in
machine damage.
The pump conducts coolant from the water tray through the Loc-line valve and up through
an opening in the blade clamp assembly.
1. Plug the hole in the water tray with the rubber stop supplied in the bag assembly.
2. Connect the elbow fitting supplied with the pump to the threaded pump outlet. Install the
female hose fitting from the bag assembly to the pump elbow fitting. Lay the pump in the
water tray.
