• Keep hands and hair away from rotating parts .
• Do not leave the tool running . Do not force tool to stay in the "on"
position . Operate the tool only when hand-held .
• Do not touch the impact socket or the workpiece immediately after
operation; they may be extremely hot and could burn your skin .
• Some material contains chemicals which may be toxic . Take caution to
prevent working dust inhalation and skin contact . Follow material supplier
safety data .
OPERATING INSTRUCTION
Installing Or Removing Battery Pack
1 . Your new battery pack is not fully charged . You may need
to charge before use .
2 . Make sure the forward/reverse lever is in the neutral
position when installing or removing a battery .
3 . To remove a battery, depress the front tab and pull the
battery forward and the tool in the opposite direction .
4 . To install a battery align the tool with the battery, push
forward until click is heard indicating full installment .
Tool Operation:
• Always be sure that the machine is switched off and the
battery cartridge is removed before installing or removing the
impact socket .
1 . To install the impact socket, push the impact socket onto
the anvil as far as it will go .
2 . To remove the impact socket, simply pull the impact socket
from the anvil .
3 . To start the tool, simply pull the trigger . Release the trigger
to stop .
4 . For reversing the tool, use the forward/reverse switch on the
drive unit . The directions of the rotation are also shown on the
face of the switch .
5 . Always check the direction of rotation before operation .
6 . Use the forward/reverse switch only after the tool comes to
a complete stop . Changing the direction of rotation before the
tool stops may damage the gears .
7 . Hold the tool firmly in place, make sure the impact socket is
completely over the nut or bolt . Apply forward pressure to the
tool to the extent that the impact socket will not slip off the nut
or bolt . Pull the trigger to begin .
NOTE:
• Use the proper impact socket size for the nut or bolt that you
intend to install or remove .
• Hold the tool pointed straight at the nut or bolt . If you tighten
the nut or bolt for a time longer than it needs, the nut or bolt
or point of the driver socket may be overstressed, stripped,
damaged, etc . When tightening a standard nut or bolt in a
steel plate, the proper tightening torque can be obtained in an
extremely short time (approx . 0 .1-0 .2 seconds) .
• Turn the tool off as soon as the impact sound is heard .
• When tightening nut M6 or smaller, carefully adjust pressure
on the switch trigger so that the nut is not damaged .
8 . The tightening torque is affected by a wide variety of factors

WARNING:
MISUSE or failure to follow the safety rules stated in this instruction
manual may cause serious personal injury.
including the following .
• When the battery cartridge is discharged almost completely,
voltage will drop and the tightening torque will be reduced .
• Driver bit or socket bit: Failure to use the correct size driver
bit or socket bit will cause a reduction in the tightening torque .
• Driving a bolt: Even though the torque coefficient and the
class of bolt are the same, the proper tightening torque will
differ according to the diameter of the bolt .
9 . Even if the diameter of the bolts are the same, the proper
tightening torque will differ according to the torque coefficient,
the class of the bolt and the bolt length .
10 . The manner in which the tool is held or the driving
position of the material to be tightened will affect the torque .
Make sure that the impact wrench is turned off and the
battery cartridge is removed before carrying out any work
on the tool. To maintain product safety and reliability,
repairs, maintenance or adjustments should be carried
out by an authorized service center.

BRUSHLESS Matco tools will function normally when
using the MCL2040LB battery . Since the connection styles
are different it is required to utilize the adapter MCL20BADP .
Connect the adapter to the BRUSHLESS tool then slide the
MCL2040LB battery in place until a click is heard and the
release buttons locks into place .
FAQ
Question: Can I use the adapter (MCL20BADP) connected to
the MCL2040LB battery and charge it on the MCLCHRG6?
Answer: No . The adapter does not have the proper circuitry
to allow it to be used to charge the battery . To charge the
MCL2040LB remove the adapter and utilize the MCLCHRG5
or MCL1840CHRG .
