MAKESafe Tools PTB-V120-P1 User Manual page 2

You have just purchased a safety device and this manual contains critical safety instructions on
the proper setup, operation, maintenance, and service of this safety device. Keep this
document readily available, refer to it often, and use it to instruct other operators.
Failure to read, understand and follow the instructions in this manual may result in property
damage and/or serious personal injury - including amputation, electrocution, or death. The
owner of this device is solely responsible for its safe use.
The manufacturer will not be held liable for injury or property damage from negligence, failure
to adhere to this documentation, improper training, device modifications or misuse.
This safety device is intended to be installed as a retrofit to a very specific class of power tool.
Read and understand the intended use and limitations of this device before installing it.
The manufacturer has made reasonable attempts to test and describe this device's
compatibility with different power tools but cannot certify or guarantee its compatibility with any
one power tool. It is the responsibility of the owner of this device to follow the guidance
provided below to determine compatibility.
All induction motors, such as those running power tools, have inherent limitations on their
maximum number of starts per hour and their minimum rest time between starts, as described
in NEMA MG 10, Table 8. Motor braking contributes additional heat to the motor and can
significantly impact these values. Reduce allowable startups per hour by a factor of 0.5 and
increase rest time between starts by a factor of 1.5, until such time that a more precise factor
can be determined by the operator for a specific tool and set of conditions.
When this device is in braking mode, it delivers high voltage direct current to your tool. If you
operate the tool switch during braking, you will destroy or significantly reduce the life of your
tool switch while also increasing the risk of electrical fire. Never operate your tool switch during
braking and always cover the tool switch as described in the instructions below.
DISCONNECT ALL SOURCES OF POWER PRIOR TO SERVICING THIS DEVICE.
Retain this manual and include it with the original user manual for the machine on which this
device is installed.
