before making any adjustments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate the power tool. Power tools are dangerous in the
hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these instructions,
taking into account the working conditions and the work to be performed. Use of the power tool
for operations different from those intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical replacement
parts. This will ensure that the safety of the power tool is maintained.
(B) Additional safety rules for impact wrenches
a) Recommendation for the operator to wear hearing protection. Wear ear protectors with
drills. Exposure to noise can cause hearing loss.
b) Use auxiliary handles (if supplied with the tool). Loss of control can cause injuries.
c) Hold power tool by insulated gripping surfaces when performing an operation where the
accessory may contact hidden wiring. Accessory contacting a "live" wire may make exposed metal
parts of the power tool "live" and shock the operator.
d) Hold the power tool with a firm grip with both hands (if possible) and keep a good balance.
The tool is best guided with both hands. If bit gets locked, a strong torque reaction may occur when
screwing in or loosening screws.
e) Use appropriate detectors to determine if utility lines are hidden in the work area or call the
local utility company for assistance. Contact with electric lines can lead to fire and electric shock.
Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or
electric shock.
f) Secure the workpiece. Never hold the workpiece in your hand or across your legs or against
your body. A workpiece clamped with clamping devices or in a vice is held more secure than by
hand. An unstable workpiece can cause loss of control of the tool and/or injury.
g) Position yourself so as to avoid being caught between the tool or auxiliary handle or bit and the
wall or posts or workpiece. Should the bit become jammed in the workpiece, the reaction
torque of the tool could crush your body.
h) Do not use dull or damaged bits and/or accessories. Dull or damaged bits/accessories have
a greater tendency to get jammed in the workpiece, or to break, or to be ejected.
i) When installing a bit/accessory in the chuck, insert the shank of the bit/accessory well inside the
chuck. If the bit / accessory is not inserted deeply enough, the grip of the chuck over the shank of the bit
/ accessory is greatly reduced likely to increase the risk of loss of control. After inserting the bit, pull on it,
so as to ensure that it is properly locked.
j) If the bit becomes bound or jammed in the workpiece, immediately stop the tool by
releasing the trigger switch, then reverse the rotation direction and slowly squeeze on the
trigger switch to release and remove the bit. Be ready for strong reaction torque likely to cause a
kickback.
k) Never grasp the tool (the chuck or the bit/accessory) while in motion and never place your hands
too close to the spinning chuck or drill bit. Laceration hazard.
