SECTION 1 GENERAL INFORMATION AND 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
persons 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
including 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
distributor, or call your Customer Service Representative to order more decals.
Always properly dispose of all by-products, including debris, coolant and oil.
Safety instructions are listed in this section by the following operations:
Electrical Safety
Blade Handling
Machine Operation
1.1 Electrical Safety

1.4 Noise Level
See Table 1-1. The level of noise generated by the BMT300 Toothsetter is given in the
table below1.
1.5 Motor Specifications
See Table 1-2. The motor specifications are listed below.
1.6 Technical Data
See Table 1-3. See the table below for technical data on the BMT300 Toothsetter.
Max. Noise Level
BMT300BMT300 74.8 dB (A)
TABLE 1-1
1. The measured values refer to emission levels, not necessarily to noise levels in the workplace.
Although there is a relation between emission levels and exposure levels, it is not possible to
determine with certainty if preventives are needed or are not needed. The factors affecting a
current level of noise exposure during work are inter alia room characteristics and characteristics
of other noise sources, e.g. number of machines and machining operations nearby. Also, the
permissible exposure level value may vary depending on country. This information enables the
machine’s user to better identify hazards and a risk.

1.9 Start Up Modes
Press the MENU button once to get to the menu selection mode. Press the UP or DOWN
button twice to find the MODE menu.
The following options are available in the MODE menu:
Set Single Clamp - The setter clamps and checks the blade tooth. The tooth
is set if necessary. The blade is unclamped, and moved to the next tooth. The
setter skips the pattern recognition while using the Set Single Clamp mode.
The final tooth correction follows, i.e. if the toot is unbend not enough - setter
bend it, if the tooth is bended too much - setter unbend it.
Set Double Clamp - Just like using the Set Single Clamp mode, but the blade
is clamped once more after releasing and checked for the tooth set. The pat-
tern recognition is turned off. The Set Double Clamp mode is more accurate
but more time-consuming.
Pattern Single Clamp - The mode similar with the Set Single Clamp mode,
but the setter checks the teeth pattern. See System Parameters, for how to set
the maximum number of pattern errors (only 1 in most cases). When the num-
ber of possible errors is exceeded, the setter stops the setting process and the
"Error --- Blade Set Pattern" message appears.
Pattern Double Clamp - Using the Pattern Double Clamp mode, the setter
works like using the Pattern Single Clamp mode, but the blade is released and
clamped again to check the tooth set. The Pattern Double Clamp mode takes
more time to set the whole blade but it is more accurate.
Inspection - After the Inspection mode has been selected, the setter checks
the tooth set only. The process is stopped when the number of pattern errors
has been exceeded.
NOTE: The Pattern Single Clamp and Pattern Double Clamp modes can be used only
when the tooth setter has been set to push every tooth of the blade.
Push the ENTER button to select the mode you want the setter to operate.

1.10 Blade Settings
Press the MENU button on the control panel once to enter the BLADE SETTINGS mode.
Use the UP or DOWN arrows if necessary. Push the ENTER button to enter the settings.
The following options are available in the BLADE SETTINGS menu:
No. of teeth to set - The number of teeth to be set. Press ENTER to see the
"Qty Teeth To Set #" message. Use the UP and/or DOWN arrows to enter the
number of teeth to be set. See Table 1-1 below. NOTE: Enter the number of
teeth divided by three if the setter pushes every third tooth of the blade.
Upper Set Limit - The desired tolerance for the upper set. When entered the
"Upper Set Limit #" appears. Use the UP and/or DOWN arrows to set the limit
value. The upper set limit is the upper limit of the tolerance for the blade tooth
set. If the tooth set exceeds the upper limit, the setter adds the tooth to the
group of teeth with the incorrect set. The setter stops when the number of set
errors is exceeded.
Lower Set Limit - The desired tolerance for the lower set. When entered the
"Lower Set Limit #" appears. Use the UP and/or DOWN arrows to set the limit
value. The lower set limit is the lower limit of the tolerance for the blade tooth
set. If the tooth set is below the limit, the setter adds the tooth to the group of
teeth with the incorrect set. The setter stops when the number of set errors is
exceeded.
Maximum Raker Set - The desired tolerance for raker set teeth. When
entered the "Max. Raker Set #" appears. Enter the desired tolerance for rak-
ers. Use the lowest possible tolerance that still allows the setter to efficiently
operate. If the raker set exceeds the provided limit, the tooth set error
appears.

SECTION 2 OPERATION
2.1 Machine Setup
1. Install the blade to the setter. Rest the blade on the inside of the two blade guides and in
between both blade clamps. Center the blade on the setter stand. Position the three
adjustable blade guide supports so they lightly touch the inside of the blade. The adjust-
able guides should lightly support the blade and keep it from wobbling.
2. Use the blade height knob to adjust the blade height so the bottom of the gullet is aligned
with the top of the blade clamps.
See Figure 2-1.

3. Adjust the pusher pin. To adjust, manually rotate the pusher adjustment knob. Turn the
pusher adjustment knob clockwise to increase the pusher pin force, turn the knob coun-
terclockwise to decrease the force. Make sure the tooth is not being bent too much. Read
the display to check the tooth set while adjusting.
IMPORTANT! Avoid pinching fingers or hand when turning
the cam.
DANGER! Keep all persons away from moving parts when
operating this machine. Failure to do so will result in serious
injury.
4. Adjust the index ramp. The push pawl should push one tooth at a time. To adjust, loosen
the blade ramp set screw. Slide the blade ramp as necessary and retighten the set screw.
The pawls should contact the point of the tooth where the face and gullet meet. Manually
rotate the index cam until the pawl is against the tooth radius. Loosen the index pawl
adjustment nut to position the pawl as necessary. Retighten the nut when adjustment is
complete.
2.2 3" Blade Support Setup (Option)
See Figure 2-2.
1. Position the optional blade supports on proper sides of the toothsetter. Using the
connectors (1), connect the right and left blade supports with the toothsetter arms.
2. Position the blade support kits so that the blade is not too loose and moves freely during
the setting operation.
3. Install the bushings (2) on the guide assembly (3) - see Detail B in the figure below.
Adjust the height of the third blade support (5) and rest the toothsetter arm (4) on this
support.
4. The blade supports should be adjusted vertically so that the bottom of the blade is at the
same height along entire length of the blade.
