6 . Confirm whether the socket has any crack in it.

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided, this
plug will fit into a polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install the proper outlet. Do not change the
plug in any way.

Double Insulation

Double insulated tools are constructed throughout with two separate
layers of electrical insulation or one double thickness of insulation
between you and the tool's electrical system. Tools built with this
insulation system are not intended to be grounded. As a result, your
tool is equipped with a two prong plug which permits you to use
extension cords without concern for maintaining a ground
connection.
NOTE: Double insulation does not take the place of normal safety
precautions when operating this tool. The insulation system is for
added protection against injury resulting from a possible electrical
insulation failure within the tool.
CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLAC-
EMENT PARTS. Repair or replace damaged cords.
Use of Extension Cord s
Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current
your product will draw. An undersized cord will cause a drop on line
voltage resulting in loss of power and overheating. The table shows the
correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller the gauge
n u m b e r, the heavier the cord
When the work area is far away from the power source, use an
extension cord of sufficient thinkness and rated capacity. The

extension cord should be kept as short as practicable.

WA R N I N G : Avoid electrical shock hazard. Never use this tool with
a damaged or frayed electrical cord or extension cord. Inspect all
electrical cords regularly. Never use in or near water or in any
environment where electric shock is possible.
S w i t c h
The switch in this machine functions as a motor
switch and a rotational direction selector switch.
The lower part of the switch, marked with an R
(right) will run the motor clockwise to tighten a bolt.
The upper part of the switch, marked L (left) will
run the motor counterclockwise to loosen the bolt.
To stop the motor, release the switch.
CAUTION: Be sure to turn the switch OFF and wait until the motor
comes to a complete stop before changing direction of rotation.
Switching direction of rotation while the motor is running may cause
serious damage to the tool and the operator may loose control.
Mounting a Socket
Align the detent pin located in the square
part of the anvil with the hole in the hex
socket. Push in the detent pin and mount
the socket to the anvil. Ensure that the
detent pin is fully engaged in the hole. When
removing the socket, push the detent pin in
