Additional Specific Safety Rules
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the operator.
• Keep hands away from moving parts. Never place your hands near the cutting area.
• Use extra caution when cutting overhead and pay particular attention to overhead
wires which may be hidden from view. Anticipate the path of falling branches and debris
ahead of time.
• Do not operate this tool for long periods of time. Vibration caused by the operating
action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to
provide extra cushion, take frequent rest periods, and limit daily time of use.
CAUTION: Shock hazard. When sawing into walls, floors or wherever "live" electrical wires
may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool only
by the plastic handle and housing to prevent electric shock if you saw into a "live" wire.
CAUTION: Wear appropriate personal hearing protection during use. Under some con-
ditions and duration of use, noise from this product may contribute to hearing loss.
CAUTION: When not in use, place tool on its side on a stable surface where it will not
cause a tripping or falling hazard. Some tools with large battery packs will stand upright on
the battery pack but may be easily knocked over.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory pro-
tection appropriate for the dust exposure. Direct particles away from face and body.
• The label on your tool may include the following symbols. The symbols and their definitions
are as follows:
n o..............no load speed
..............Class II Construction
..............safety alert symbol
.../min ........revolutions per minute
Important Safety Instructions for Battery Packs
Your tool uses a D
WALT battery pack. When ordering replacement battery packs, be sure to
include catalog number and voltage: Extended Run-Time battery packs deliver more run-time
than standard battery packs. Consult the chart at the end of this manual for compatibility of
chargers and battery packs.
NOTE: Your tool will accept either standard or Extended Run Time battery packs. However, be
sure to select proper voltage. Batteries slowly lose their charge when they are not on the
