MCL1638HPIW 16V 3/8" High Power Impact Wrench
Service
• Tool service must be performed only by the MATCO
authorized service centers listed. Service or maintenance
performed by unqualified personnel may result in a risk of
injury. Repair by unqualified personnel, use of unauthorized
parts, and failure to follow maintenance instructions may
create a risk of shock or injury.
SAVE THESE INSTRUCTIONS!
SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product replace strict
adherence to cordless product safety rules. If you use this
tool unsafely or incorrectly, you can suffer serious personal
injury.
• Hold tool by insulated gripping surfaces when performing an
operation where the accessories may contact hidden wiring.
Contact with a "live" wire will also make exposed metal parts of
the tool "live" and shock the operator.
OPERATING INSTRUCTION
Installing Or Removing Battery Pack
(See Fig.1, Fig.2)
1. Your new battery pack is not fully charged. You may need to
charge it before use.
2. Make sure the switch is in the "off" position before insertion/
removal of a battery pack.
3. To remove a battery pack, depress both tabs on either side of
the battery and pull downward.
4. To insert a battery pack, align the battery with the tool
housing and push battery inward until click indicating battery
is fully installed.
Charging The Battery Pack
1. Battery may not charge when it is above a certain preset
temperature limit. Allow temperature of battery to cool before
charging.
2. The charge process will take less than one hour.
3. After charging, unplug the charger from the power source
and stow away in a safe place.
Tool Operation:
• Always be sure that the tool is switched off and the battery
pack is removed before installing or removing impact sockets.
1. To install an impact socket, firmly push the impact socket onto
the anvil as far as it will go.
2. To remove the impact socket, pull the impact socket from the
anvil.
3. To start the tool, pull the trigger. Release the trigger to stop.
4. For reversing the tool, use the forward/reverse switch located
above the trigger. The direction 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 will cause damage.
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.
MCL1638HPIW
• Be aware that this tool is always in operating condition, because it
does not have to be plugged into an electrical outlet.
• Always be sure you have firm footing.
• Be sure no one is below when using the tool in high locations.
• Hold the tool firmly and use both hands.
• 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.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.

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 impact socket may be overstressed, stripped, damaged,
etc.
When tightening a 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 the battery pack is almost completely discharged, the
voltage will drop and the performance will be reduced.
• Impact socket: Failure to use the correct size impact socket
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 is 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 pack 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.
