RUNNING NUTS AND bOlTS
Variable speed control must be used with caution for driving nuts and
bolts with socket set attachments. The technique is to start slowly,
increasing speed as the nut or bolts run down. Set the nut or bolt
snugly by allowing the impact driver to impact the nut to the desired
torque. This is a achieved by the time the impact driver is allowed to
impact the nut. A very short impact of say 0.5 seconds will be a low
torque. An impact of 5 seconds will result in a very high torque. It is
ALWAYS advisable to test the torque and determine what time frame is
required to achieve the desired result.
wARNING. This impact driver is capable of tightening fasteners to
a very high torque. Over tightening can result in shearing bolts and
screws, especially if low quality fasteners are used. Do Not over tighten
fasteners and impact only to achieve the desired torque.

WARNING!
Read all safety warnings and all
instructions. Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious injury.
This unit may not be used by people (including children) with reduced
physical, sensory or mental capacities, with a lack of experience and
without the appropriate knowledge, unless they are supervised by
someone who is responsible for their safety or have been instructed by
such a person with regard to how the unit is to be operated.
Children should be supervised to ensure that they do not play with the
device.
Save all warnings and instructions for
future reference
1). WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas invite
accidents. Rags, cloths, cord, string and similar items should never
be left around the work area
• Do not operate power tools in explosive environments, such as in
the presence of flammable liquids, gases, or dust. Power tools create
sparks, which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool.
Distractions can cause the operator to lose control.
2). ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify the plug in
any way. Do not use any adapter plugs with grounded power tools.
Unmodified plugs and matching outlets will reduce risk of electric
shock.
• Avoid body contact with grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is increased risk of electric shock if
your body is grounded.
• Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp
edges or moving parts. Replace damaged cords immediately.
Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors,use an extension cord suitable
for outdoor use.Use of a cord suitable for outdoor reduces the risk of
electric shock.
• To reduce the risk of electric shock, the manufacturer recommends
the use of a residual current of 30mA or less at all times.
3). PERSONAL SAFETY
• To reduce the risk of electric shock, the manufacturer recommends
the use of a residual current of 30mA or less at all times.
• Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired
or under the influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in serious
personal injury.
• Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes,
hard hat, or hearing protection will reduce personal injures.
• Prevent unintentional starting. Ensure the switch is in the “off”
position before connecting to power source and/or battery pack,
picking up or carrying the tool. Carrying power tools with your finger
on the switch or energising power tools that have the switch on
invites accidents.
• Remove any adjusting key or wrench before turning the power tool
on. A wrench or key left attached to a rotating part of the power tool
may result in personal injury.
