OPERATION
Your Impact Wrench is designed to tighten or loosen bolts and nuts with up to 220 foot-pounds of torque. It
comes with a 1/2” square anvil for attaching 1/2” square drive impact sockets, extensions, etc. This tool is
shipped completely assembled. No additional assembly time or special tools are required.
WARNING:
To reduce the risk of serious personal injury, read and follow all
important safety warning and instructions before using this tool.
WARNING:
Always be sure the tool is disconnected from the power source
before making any adjustments or setting up. Failure to disconnect or unplug the tool
may cause accidental starting, resulting in serious personal injury.
NOTE:
Always Check that the power supply corresponds to the voltage on the ratings
plate.
STARTING AND STOPPING THE TOOL
To start the tool rotating in a clockwise direction,
depress the bottom of the switch (1-fIG 1). The bottom
portion of the switch is marked “f”, indicating forward (clockwise) rotation.
To start the tool rotating in a counter-clockwise direction,
depress the top of the switch. The top portion of
the switch is marked “R”, indicating reverse (counter-clockwise) rotation.
NOTE
:
Allow the motor to stop before reversing the direction of rotation to prevent
motor damage
.
To stop the tool,
release the switch.
SELECTING AND USING SOCKETS
WARNING:
Use only sockets rated for IMPACT DUTY. Other types of sockets
may shatter when used, endangering you or others around you.
WARNING:
Always be sure that the tool is switched off and unplugged before
performing any work on the tool.
WARNING:
Do not use sockets with drives smaller than 1/2”. You may use
impact socket adapters to use impact sockets with drives greater than 1/2”.
use only impact duty rated sockets and adaptors and always use the correct size socket for the bolts and
nuts being worked. An incorrect sized socket will result in inaccurate and inconsistent fastening torque and/or
damage to the bolt or nut.
To install the socket
, align the socket's square drive base with the impact wrench square drive. Push the
socket onto the tool's drive until it locks into place.
To remove the socket
, simply pull it off.
APPLICATIONS
IMPACTING TECHNIQUE
The tightness achieved when impacting a bolt, nut or screw is proportional to the length of time the impact
action is applied. Avoid excessive impacting of the fastener or workpiece to prevent damage, especially when
working with smaller fasteners.
Practice with different fasteners and applications to become familiar with the impacting requirements of each
type. When making these practice runs, make a note of how long each was impacted. Then measure the
tightness of each fastener with a hand torque wrench, then compare the time and tightness information to
help you judge how
long to impact various fasteners to achieved a desired torque. If the fasteners are too tight,
reduce impacting time. If they are too loose, increase the impacting time. Repeat the practice procedure with
new fasteners until you can determine the amount of impacting time required to achieve the desired tightness.
