Calibration - MAKESafe Tools PTB-V120-P1 User Manual

While the MAKESafe Power Tool brake is capable of stopping your tool instantly, this sudden
action should be avoided. The purpose of this calibration section is to find an optimal braking
setting for your power tool.
You have two means of adjustment on this safety device, described below:
Braking Torque
Controls how strong of a braking force
is applied to your motor during braking.
Notes on Calibration:
● The first calibration step will apply a very small braking torque for a very short time and may
not be noticeable. This is normal. Proceed with calibration, making only incremental changes
for each braking attempt.
● We recommend finding a braking torque and braking time combination that brings your power
tool to a complete stop in between one and three seconds. A good rule of thumb is to aim for
a braking time equivalent to or greater than the time it takes your tool to come up to speed
during normal operation.
● You will hear an audible buzzing sound during and after braking. This is normal. Calibrate the
device such that there is a buzzing sound for approximately 0.5 seconds after the tool has
come to a complete stop.
Making Adjustments:
Adjustments are made by inserting a small flathead
screwdriver into the holes on the side of the brake
enclosure and gently turning counter-clockwise (to
turn down) or clockwise (to turn up) the respective
setting. You will feel the adjustment hit a stop at the
maximum and minimum values. This only requires
gentle turning force - excessive force on the adjuster
can damage the device.
Calibration Steps:
1. Find the braking torque and braking time adjustment and use a small screwdriver to confirm
that it is turned counter-clockwise as far as it will go. This will set the braking torque and
braking time to the minimum for your first test. This only requires gentle turning force -
excessive force on the adjuster can damage the device.
2. Turn on your power tool by using the green start button on the control panel. It should start
normally.
3. Once your power tool has come up to speed, press the red stop button on the control panel.
This will immediately disconnect power from the tool and apply a braking torque for a set
period of time.
4. If this braking action does not bring your power tool to a complete stop, increase your braking
period or braking torque, making small incremental adjustments. Never turn an adjustment
more than 1/8 of a turn at any one time.
5. Repeat until you achieve the desired result.
