5. Do not force tool. It will do the job better and more safely at the rate for which it was
intended. Do not use inappropriate attachments in an attempt to exceed the tool
capacity.
6. Use the right tool for the job. Do not attempt to force a small tool or attachment to
do the work of a larger industrial tool. There are certain applications for which this tool
was designed. Do not modify this tool and do not use this tool for a purpose for which
it was not intended.
7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.
8. Use eye and ear protection. Always wear ANSI approved impact safety goggles.
Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI
approved dust mask or respirator when working around metal, wood, and chemical
dusts and mists.
9. Do not overreach. Keep proper footing and balance at all times. Do not reach over
or across running machines.
10. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect
tool cords periodically and, if damaged, have them repaired by an authorized
technician. The handles must be kept clean, dry, and free from oil and grease at all
times.
11. Disconnect power. Unplug battery when not in use.
12. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before plugging it in.
13. Avoid unintentional starting. Be sure the switch is in the Off position when not in
use and before plugging in battery. Do not carry any tool with your finger on the
trigger, whether the battery is plugged in or not.
14. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When cutting these materials extra care should
be taken to avoid inhalation and minimize skin contact.
16. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified

18. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
19. Use proper size and type extension cord. If an extension cord is required for the
charger, it must be of the proper size and type to supply the correct current to the
charger without heating up. Otherwise, the extension cord could melt and catch fire, or
cause electrical damage to the charger. This charger requires use of an extension cord
with up to 10 amps capability (up to 50 feet), with wire size rated at 16 AWG. Longer
extension cords require larger size wire. If you are using the tool outdoors, use an
extension cord rated for outdoor use. (signified by “WA” on the jacket).
20. Maintenance. For your safety, service and maintenance should be performed
regularly by a qualified technician.
21. Do not disable blade guard. Do not saw without proper blade guard in place.
22. Examine blade before using. Before each use, examine blade for chips, cracks, or
other damage. Do not use if damaged.
23. Do not use without first mounting saw to a workbench.
24. Check for tightness of all saw adjustments before using.
25. Keep hands away from moving saw blade. If the workpiece to be cut is less than 4
inches long, do not hold with your hand, use a clamp. Do not remove jammed or cutoff
pieces until the saw blade has stopped and the battery is removed.
26. Cut only the proper type of material. Never cut ferrous metals or masonry.
Battery Safety Precautions
Note: Always switch to a fresh battery when tool performance begins to diminish. Severe heat is most destructive to a
battery; the more heat generated, the faster the battery loses power. A battery that gets too hot can be permanently damaged. Never
over-discharge a battery by using the tool even after tool performance is decreasing. Never attempt to discharge a tool’s battery by
continuing to pull the tool trigger. When tool performance begins to diminish, stop the tool, re-charge the battery and use the
fresh battery for optimal performance.
1. Read all instructions and warnings on the battery before charging the battery.
2. To avoid accidents, charge the supplied battery only. Do not use a different charger
with this battery. Charging room temperature: 500 F - 1040F.
3. Do not expose the battery to rain or wet conditions.
4. To avoid damage of cable and plug, never pull the cable to disconnect the charger.
5. Do not use the charger if the cable or plug are damaged.
6. Repairs should be carried out by a qualified technician.
7. Do not touch the battery poles with any conductive source.
8. Do not store the battery in a box with other metal objects.
9. Properly recycle or dispose of Ni-Cd battery when it no longer recharges. Do not
throw the battery in a fire. Contact your local hazardous waste disposal authority for
proper disposal.
Note: Performance of this tool may vary depending on variations in battery charge.

Operation
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities, contain chemicals known [to the State of California] to cause
cancer, birth defects or other reproductive harm. Some examples of these chemicals
are:
•Lead from lead-based paints
•Crystalline silica from bricks and cement or other masonry products
•Arsenic and chromium from chemically treated lumber
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 microscopic particles. (California Health & Safety Code 25249.5,
et seq. )
Auxiliary Wood Fence
To help avoid small, short cut pieces of stock from being caught by the blade or shot off, it
is recommended to mount an auxiliary wood fence (not supplied) to the saw’s metal Fence
(55).
