4. Minor adjustments may be needed to
help the chain fit properly between
the two discs.
5. To install the disc on the EHK, use
the same installation technique as
described previously in “Changing
the Disc.”
CAUTION: When installing the disc on
the EHK, make sure the teeth are
pointing in the same direction as the
arrow located on the EHK’s head. The
rakers should be on the left side of the
teeth with the tungsten carbide tips
facing counter-clockwise.
HOLDING THE EHK
For the most control over the EHK, lightly
grip the area just below the gear head,
with the EHK resting on your fingertips.
Avoid blocking the air vents and try not to
press the locking button while trimming.
CAUTION: The locking button exists so
that it is easier for you to change discs
and sharpen the chainsaw teeth.
Accidently depressing the locking
button during operation will cause the
locking button to vibrate and chatter.
This indicates that the locking button is
trying to engage the drive shaft. While
not usually damaging, care should be
taken to not engage the locking button
during operation.
Pressing the locking button with
FORCE while the EHK is running could
damage and/or destroy the locking
button. Therefore, we recommend that
you always hold the Electric Hoof Knife
so that your fingers are not touching
the locking button.
ELECTRICAL SAFETY
The EHK is equipped with a double
polarized plug (one blade is wider than
the other) for safety. This plug will fit in
a polarized outlet only one way. If the
plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a
qualified electrician to install a polarized
outlet. Do not change the plug in any way.
Double insulation eliminates the need for
the three wire grounded power cord.
We recommend that you plug the EHK
into a grounded outlet or use a ground
fault interrupter (GFI) extension cord.
Avoid body contact with grounded
surfaces such as pipes, fencing, etc.
There is an increased risk of electric
shock if your body is grounded.
Contact with a “live” wire will make
exposed metal parts of the EHK “live”
and shock the operator.
Do not expose the EHK to rain or wet
conditions. Water entering the EHK will
increase the risk of electric shock.
Do not abuse the cord. Never use the
cord to carry the EHK or to pull the
plug from an outlet. Keep the cord
away from heat, oil, sharp edges or
moving parts. Do not cut the power cord.
If the cord is damaged, do not use the
tool. You can send it back to DeWolf &
Associates, LLC for repairs. Never
attempt to fix the cord yourself.
When operating the EHK outside, use
an outdoor extension cord marked with
5
the designation letter “W”. These cords
are rated for outdoor use and reduce the
risk of electric shock.
Avoid accidental starting. Be sure the
power switch is in the off position
before plugging the EHK in. Plugging
in an EHK that has the power switched
on is dangerous. Do not carry the EHK
with your finger on the power switch.
PERSONAL SAFETY
Before use, inspect the chain, paying
specific attention to the tungsten
carbide teeth. If any of the teeth are
bent, broken, chipped, damaged, missing,
or overly worn, you will need to replace
the chain as it could be dangerous to use.
A well-maintained EHK with sharp teeth is
less likely to bind and is easier to control.
Keep your work area clean and well lit.
Always keep yourself and the EHK
between the horse and the power source.
This will make cord management easier
and decrease the likelihood of accidents.
Do not operate the EHK in an explosive
atmosphere, such as in the presence of
flammable liquids, gases, or dust. The
EHK can create sparks which may ignite
the dust or fumes. Keep bystanders away
while operating the EHK.
Stay alert, watch what you’re doing, and
use common sense during operation.
Do not use the EHK while tired or
under the influence of drugs, alcohol,
or medication. A moment of inattention
while operating the EHK may result in
serious personal injury.
Dress properly. Always wear proper
and adequate eye protection, gloves,
and long-legged trousers. Do not wear
loose clothing or jewelry. Contain long
hair. Keep your hair, clothing, and gloves
away from moving parts as they may get
caught and cause injury.
Use safety equipment and always wear
eye protection. Dust mask, non-skid
shoes, hard hat, and/or hearing protection
must be used for appropriate conditions.
Use the EHK only in ventilated areas.
Using personal safety devices & working in
a safe environment reduces risk of injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the
EHK in unexpected situations.
Do not reach in the area of the rotating
wheel. The proximity of the rotating
wheel to your hand may not always be
obvious. Do not touch the disc or attempt
to remove any material from the disc while
it is still spinning.
EHK USE AND CARE
Always be aware of the switch location,
when placing the EHK down or when
picking the EHK up. You may
accidentally activate the switch.
Store an idle EHK out of reach of
children and other untrained persons.
The EHK is dangerous in the hands of
untrained users.
Check for misalignment or binding of
moving parts, breakage, or any other
condition that may affect the EHK’s
operation. If damaged, have the EHK
serviced before using. Accidents can be
caused when operating a poorly
maintained EHK.
