POWer ManageMenT sysTeM
and TOOl OPeraTIOn
This tool includes a power management system that allows the operator
to adjust the amount of output power in the clockwise direction
(forward). There is no power management system present in the
counter-clockwise direction (reverse). To adjust the power output in the
forward direction, turn the dial shown below left or right in the desired
power direction. Power output is indicated by enlarging black swoosh
on back housing. Lowest power setting indicated by thin swoosh area
with highest power setting being thickest swoosh area.
The Power management system is only for reference and do not act as
specific power settings. This tool includes a tip valve variable speed
trigger design that further allows the operator to reduce the power
output.

released. A void d irect c ontact w ith a ccessories d uring a nd
after use. Gloves will reduce the risk of cuts or burns
• Keep away from rotating end of tool. Do not wear
jewelry or loose clothing. Secure long hair. Scalping
can occur if hair is not kept away from tool and
accessories. Choking can occur if neckwear is not
kept away from tool and accessories.
• Use accessories recommended by Matco Tools.
• Use only impact wrench sockets and accessories on
this tool. Do not use hand sockets and accessories.
• Do not lubricate tools with flammable or volatile liquids
such as kerosene, diesel or jet fuel.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace damaged labels.
• Impact wrenches are not torque control devices.
Fasteners with specific torque requirements must be
checked with suitable torque measuring devises after
installation with an impact wrench
• This product may contain one or more chemicals known
to the State of California to cause cancer and birth
defects or other reproductive harm. Wash hands
thoroughly after handling.
This impact wrench is rated at 1/2" SAE bolt size. Rating must be down
graded for spring U bolts, tie bolts, long cap screws, double depth nuts,
badly rusted conditions and spring fasteners as they absorb much of
the impact power. When possible, clamp or wedge the bolt to prevent
springback.
Soak rusted nuts in penetrating oil and break rust seal before removing
with impact wrench. If nut does not start to move in three to five
seconds use a larger size impact wrench. Do not use impact wrench
beyond rated capacity as this will drastically reduce tool life.
NOTE: Actual torque on a fastener is directly related to joint hardness,
tool speed, condition of socket and the time the tool is allowed to
impact.
Use the simplest possible tool-to-socket hook up. Every connection
absorbs energy and reduces power.
