4．Grinding head motor 250W110V60Hz

Grinding wheel dressing
If the angle of the bevel on the grinding wheel is off from the angle of the saw tooth, it should
be dressed. Trimming can be done with a diamond pen, or a hard ceramic wheel can be used.
Grinding the back of the tooth
If the back of the tooth is to be ground, this can be achieved by adjusting the relative
positions of the cams 14 and 15. This step needs to be performed after the blade has been
installed onto the grinder. The specific operation is: stop state, loosen the screw on the cam 14,
and point the pointer on it to the scale 5, and then tighten the screw, then turn the cam by
hand to observe the contact between the back of the tooth and the grinding wheel when
pushing the tooth. If it is not in contact, loosen the screw again, so that the index of the
pointer on the cam 14 is increased. (If the contact is too tight, the index must be made
smaller.) When the cam is rotating (during the feed, for example), the front of the serration
and the tooth when the back side is in light contact with the grinding wheel, the adjustment is
basically in place. At this time, you can start the machine and observe.

Note: Before turning on the power, first adjust the lever 16 back a short distance, and then
slowly feed it to prevent the saw tooth from being worn out.
Maintenance and precautions
1. The saw blade interface must be smoothed before grinding, and there should be no
obstacles when the saw blade advances.
2. Before starting and after stopping, the feed adjustment lever 16 must be retracted by a
short distance to prevent the grinding when starting up.
3. This machine can be used in places where the altitude is not more than 1000 meters, the
ambient temperature is -15°C to 40°C, and the relative humidity of the surrounding air is
not more than 95%. The temperature rise of the motor is not more than 80°C.
4. The linear guides are to be lubricated once every three months, and the other rotating
parts are lubricated with oil as needed.
5. Clean off dust frequently and keep the countertop and electrical system clean and dry.
6. To replace the grinding wheel, just loosen the screw on the rounded corner of the
protective cover and remove the outer cover. Before replacing, you should first check
whether the speed rating of the new grinding wheel is consistent with the specifications
listed in the manual. If it is lower than the regulations, it should not be used. When
installing the new grinding wheel, the soft gasket on the chuck and the grinding wheel should
be properly placed, and the grinding wheel should be balanced, and there should be no
obvious yaw or vibration. The clamping wheel nut should also not be over-tightened to
prevent the wheel from cracking. After the grinding wheel has been replaced, re-installed
the protective cover and re-install the screws on the circumference of the housing.
7. After replacing the grinding wheel, the grinder should be test operated. The wheel
movement should be smooth and quiet, and there should be very little vibration. When
testing, you should stand to the side of the grinder for safety.

Take the band saw blade
to be sharpened, and set
it on the machine as
shown in the photo
Take special notice as to
what direction the teeth
are facing
If you set the blade on
the machine and find the
teeth are facing the
opposite way; then you
must turn your blade
inside out to reverse the
teeth
Do so with caution as the
blades are very sharp and
have plenty of spring
tension
Once the blade is facing
the correct direction,
slide it towards the
grinding wheel
The teeth should be free
and clear of the plate
that the blade is sitting
on - as seen in the photo

Now that the blade is
sitting in the correct
position, lock it into place
Loosen the small black cap
shown in the photo
Adjust Band Saw guide so
that it is snug against the
back of the blade
Tighten the black cap to
lock guide into position
Repeat the same process
with the rear guide

Now that both guides are
locked into place, set the
press plate onto the blade
Install compressor handle
and compressor support
on top of press plate
Do not tighten wing-nut
shown in picture yet
Leave this loose for now
as you will be adjusting
the upper table assembly
to line up with the
grinding stone properly

Slide the left pressure
wheel over the center of
the blade
Lock into position by
tightening wing-nut
Slide the Right pressure
wheel over the center of
the blade
In the photo shown, the
angle between the pressure
roller arm and blade is
about 90°
Orange lines to show the
intersecting angles
You don’t want that angle
to be any large than 90° as
it will cause the blade to
slowly come away from the
guides during sharpening

The blade is now set in the
machine
The next steps involve
getting the blade lined up
with the grinding stone to
do the appropriate grind on
the tooth
Now, locate this panel on
the side of the machine
Make sure the other
orange switch located just
left of this panel is in the
“off” position for now
Turn the dial up to around
the fourth dot- this is a
nice speed to use when
setting the blade up
This dial controls how
quickly the upper table
assembly moves back and
forth
Now turn the black switch
that is shown in this
picture to the “on”position
The upper table assembly
should be moving back and
forth now
The blade should be fed,
one tooth at a time by the
Push Tooth pin at this time

The other, orange switch
will still be in the “off”
position at this time - the
grinder is not spinning at
this time
Return to the round, black
handle(16), and start
turning clockwise
You will see that the upper
table assembly gradually
moves toward the grinding
stone as you do this
Your table should still be
moving back and forth
during this step
Keep adjusting until the
blade moves right up
against (but not touching)
the grinding stone
Once you are happy with
the adjustment made here,
switch off the table when
the blade is against the
grinding stone.
(still not quite touching the
stone)

The next adjustment is the
upper table position
This adjustment changes
the angle of the blade as it
contacts the grinding wheel
This adjustment is
achieved by gripping the
left pressure roller and the
right pressure roller-
circled in orange
Once gripped, pull one side
and push the other side to
achieve a change in angle in
either direction- you are
essentially turning the
whole top table left or
right in relationship to the
workbench(18)
Use this adjustment to line
up the angle of the blade
tooth with the angle of the
back of the grinding stone
You can lock the upper
table into position by
tightening the wing-nut on
the compressor
support(12)-The wingnut is
circled in orange in the 2nd
photo
Take time to line up these
2 adjustments so that the
blade is perfectly lined up
with the stone-but still not
touching

Switch the table back on,
the upper table should be
moving back and forth and
the blade should be coming
very close to the grinding
stone with the appropriate
angle
Turn the grinding motor
switch on
The table should be moving
back and forth and the
grinding stone should now
be spinning
The stone will not be
contacting the blade tooth
yet
Return to the silver handle,
located under the grinding
motor(21)
By adjusting this, you can
run the motor inwards and
outwards
Use this adjustment to line
up the grinding stone to
now touch the blade tooth
Now your machine should
be self-feeding one tooth
at a time and making a
small grind at the
appropriate angle for the
blade
Be sure to mark the start
point of the blade to
identify when the blade has
made a full circuit through
the grinder.
