whether it 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. 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 technician.
Do not use the tool if any switch does not turn On and Off properly.
16. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
17. 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.
18. Secure work. Use clamps or a vise to hold work. Do not use hands to secure.
19. Never touch moving parts. Never place your hands, fingers or other body parts near
the tool’s moving parts.
20. Never operate without all guards in place. Do not disable blade guard when cutting.

Charging Battery
The Battery does not come charged from the factory. Charge before using. Part numbers below refer to Parts
List on page 8. Charging room temperature: 500 F - 1040F.
1. Insert the Battery (#14) into the black Charger Base. The Battery will only insert one way.
2. Plug the Charger Base into a wall socket. Note: The Charger Base has an ON red light, an OFF green light,
and a SET button.
3. When the Charger Base is plugged into a wall socket, the GREEN light will go on. This shows that all
circuitry is working properly and the Charger Base is ready to charge.
4. Press the SET button to start the charge. The red light will go on and will continue to be on while the Battery
is charging. The Battery will charge in approximately 1-1/2 hours. When the RED light goes off, the Battery
charge is complete.
5. After charging, unplug the Charger Base from the wall socket.
6. Remove the Battery from the Charger Base and insert the Battery into the base of the tool.
Note: The operation time of a new battery will ramp up as it is properly used and recharged. It will take
about 5 cycles before the battery is at maximum efficiency.
Warning: If two or more batteries are to be charged, allow the Charging Base time to cool down between
charges.
Rev 09/98 REV 10/03
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.

Cutting
Warning: this tool can cause serious injury if not used properly. Read this entire
manual before using. Verify that saw blade is securely tightened and both angle
and height adjustment knobs are tight.
1. Secure rip fence or straight edge to the material to guide the saw on a straight path.
2. Place the saw base (#50) on material to be cut. Align the front notch (right edge aligns
with saw blade) on the cut line.
3. Pull the rear lock switch (safe button #45) back with the middle finger and squeeze the
switch button (#47) with the index finger. Do this before the saw blade touches the
material.
4. With the saw at full speed, move the saw slowly forward to complete the cut.
5. When the cut in complete, release the power switch button (#47). Do not set the saw
down until the blade stops turning.
Maintenance
1. Before remounting the saw blade, remove all sawdust that has accumulated around
the guard (#9), nut bolt (#1), and washer (#2).
2. Regularly inspect all mounting screws and knobs to ensure that they are properly
tightened.
3. Keep saw blades clean and sharp. Sharp blades minimize stalling and kickback.
4. Keep guards in good working order.
5. Keep motor air vent clean of dust and debris. Vacuum periodically.
6. If the tool is not operating normally, making unusual noises, or appears defective, stop
using it immediately and get it repaired.
7. Clean tool with a damp cloth and light detergent. Do not use solvents as they can
damage and crack the plastic parts.
