WARNING: read all safety warnings and instructions
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE THESE INSTRUCTIONS – this Operator’s Manual contains important safety and operating instruction for 3M Power Supply.
To reduce the risk of injury. Operate the 3M Electric power tool with the 3M Power Supply. Other types of power supplies may cause personal injury or
damage.
Avoid dangerous environments. Do not operate the tool or Power Supply in rain, snow, damp or wet locations. Do not use Power Supply in the presence of
explosive atmospheres (gaseous fumes, dust or flammable materials) because sparks may be generated when inserting or removing attached tool, possibly
causing fire.
Maintain power cords and cables. When unplugging AC power cord, pull plug rather than cord to reduce the risk of damage to the electrical plug and cord.
Never carry Power Supply by its cord. Keep cord from heat, oil and sharp edges. Make sure cord will not be stepped on, tripped over or subjected to damage or
stress. Do not use Power Supply with damaged cord or plug. Have a damaged cord replaced immediately.
Do not use an extension cord unless it is absolutely necessary. Using the wrong, damaged or improperly wired extension cord could result in the risk of fire
and electrical shock. If an extension cord must be used, plug the Power Supply into a properly wired 18 AWG or larger extension cord with pins that are the same
number, size and shape as the pins of the power supply cord. See table below. Make sure that the extension cord is in good electrical condition.

Power Supply is rated for 100-240 Volt AC only (Evaluated @ 100-120 Volt AC only for U.S. and Canada). Power Supply must be plugged into an appropriate
receptacle.
Unplug Power Supply when not in use. Remove Electric tool from the unplugged Power Supply.
To reduce the risk of electric shock. Always unplug Power Supply before cleaning or maintenance. Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock
hazards.
Do not crush, drop or damage Power Supply. Do not use a Power Supply that has received a sharp blow, been dropped, run-over, or damaged in any way (e.g.
pierced with a nail, hit with a hammer, stepped on).
Do not disassemble. Incorrect reassembly may result in the risk of electric shock or fire. If it is damaged, return to 3M for service.

Original Instructions
Do not short circuit. A tool’s power supply will short circuit if a metal object makes a connection between the positive and negative contacts on the DC
connection socket (See Fig. 2). Do not place an Electric tool near anything that may cause a short circuit, such as coins, keys or nails. A short circuited power
supply may cause fire and personal injury.
Store your Electric tool and Power Supply in a cool, dry place. Do not store the tool’s power supply where temperatures may exceed 105°F (40°C) such as in
direct sunlight, a vehicle or metal building during the summer.

Power Supply Operating Instructions
TURNING POWER SUPPLY ON/OFF
CAUTION: Make certain the Switch on the Power Supply is in the “O” (OFF) position, and the AC power source is the same as specified range on the Power Supply
nameplate.
1. Connect AC power cord to AC three-prong socket and connect one end of the DC cable to the two-prong 30 VDC socket. (See Figure 2.)
2. Connect the other end of the DC cable to the Electric Power Tool. Ensure both ends of the DC cable are connected and screwed in completely.
3. Turn the Power Supply switch “ON” (“l” position). The “DC OK” LED lamp showing Green indicates proper functioning of the Power Supply. To turn off the
Power Supply off, move the swath to the “O” (OFF) position.
4. Power Supply must be installed in an environment with temperature 0-40ºC and Relative Humidity 10-80%.
5. The extrusion housing of the Power Supply is designed as a heat sink to dissipate heat generated by the Power Supply. Keep a 30 cm minimum gap around all
sides of the Power supply. (see Figure 4.)
6. Power Supply comes with a set of protective rubber frames. Then simply press onto the ends of the Power Supply if desired. (See Fig. 6.)

POWER SUPPLY TROUBLE SHOOTING
1. Problem:
“DC OK” LED Lamp is off:
Solution A:
Make sure AC power cord is plugged into the socket properly, then make sure the switch is in the ”I” (ON) position.
Solution B:
Remove the DC cable from DC connector, and make sure AC switch is on.
Solution C:
Inspect the DC cable and the AC cord for damage. If damaged, replace with parts available from 3M.
If “DC OK” LED lamp is still off after trying Solutions A - C, it means Power Supply has failed. There is no serviceable parts inside the housing. Return Power
Supply to 3M for service.
2. Problem:
“DC OK” LED Lamp is on but showing Red color.
Solution:
Power Supply is overheated. Turn power off and allow to cool for 30 minutes.
