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 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. Do not carry any tool with your finger on the trigger, 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. Guard against electric shock. Prevent body contact with grounded surfaces such as  
pipes, radiators, ranges, and refrigerator enclosures.  
17. 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.  
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. Don’t abuse the power cord. Never carry a tool by its cord. Do not yank on the cord  
to disconnect it from the outlet. Do not move bench-mounted, or floor-standing  
machines with the power cord in the outlet. Keep cord away from heat, oil and sharp  
edges.  
20. Examine blade before using. Before each use, examine blade for chips, cracks, or  
other damage. Do not use if damaged.  
21. Check for tightness on all saw blade adjustments before using.  
22. Use proper size extension cord. If an extension cord is required, it must be of the  
proper size to supply the correct current to the tool without heating up. Otherwise, the  
extension cord could melt and catch file, or cause electrical damage to the tool. This  
tool requires use of an extension cord of 0 to 10 amps capability (up to 50 feet), with  
wire size rated at 18 AWG. Longer extension cords required larger size wire. If you are  
using the tool outdoors, use an extension cord rated for outdoor use (signified by “WA”  
on the jacket).  
Note: Performance of this tool may vary depending on variations in local line voltage. Exten-  
sion cord usage may also affect tool performance.

Operation  
Operational Precautions  
1. Check the Saw Blade to make sure it does not have any missing teeth or cracks. Do  
not use a damaged Saw Blade.  
2. Check that there is enough space under and behind the workpiece for the  
reciprocation blade. Be sure that you will not be cutting through any electrical wires or  
your workbench.  
3. Do not put side-to-side pressure on the blade as it may break.  
4. Never attempt to remove material stuck in the moving parts of the saw while the saw in  
running and plugged in.

5. Always unplug the Line Cord (54) before making adjustments or repairs.  
6. Never cut stock that is thicker than 1-1/2 inches.  
7. Do not attempt to cut curves with the saw as it may break the blade.  
Warning: Always use clamps or other safe, practical ways to hold and support the  
workpiece. Holding the work by hand or against your body is unstable and may  
lead to loss of control.  
Caution: 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.  
General Operation  
1. Before plugging the Line Cord (54) into an outlet, make sure the Safety Button is not  
being pushed in and fingers are off the Trigger Switch (57).  
2. Plug the Line Cord (54) into the outlet.  
3. Grip the Saw with both hands, one on the back handle and one on the Rubber Sleeve  
(3).  
Note: The Saw is equipped with a Safety Button which must be depressed before squeezing  
the Trigger Switch (54).  
4. To start the Saw, push in the Safety Button with your thumb and squeeze the Trigger  
Switch (57) with your index finger.

Caution:When cutting metal, use cutting oil to cool the blade or damage may result to  
the blade.  
5. With the blade in motion, place it against the stock to be cut.  
Press down on the Saw to help it cut. Do not use too much force, only enough to keep  
the Saw cutting.

present, DO NOT TOUCH ANY METAL PARTS OFTHE TOOL! Hold the tool only  
by insulated grasping surfaces to prevent electric shock if you cut into a live  
wire.

6. Adjust the reciprocating speed of the Saw by moving the Speed Adjust (58) with your  
thumb (forward or backward) while the Saw is turned ON.  
7. To stop the Saw, release the Trigger Switch (57).  
8. Rotate the Variable Switch to return the reciprocating speed to its slowest position.  
Warning: If the saw jams, immediately shut off the saw and then remove the saw from  
the cutting area. If finished with the cut, shut off the saw and be careful not to  
come into contact with the blade.  
Maintenance  
1. Periodically clean or blow out the motor ventilation slots.  
This will prevent the motor from overheating.  
2. Replace the saw blade when it becomes worn, bent, or damaged in any other way.  
3. Wipe the tool with a clean cloth after every use.  
4. Over time, the Carbon Brush (46) in the motor will wear and may need replacement.  
When the Carbon Brush is completely worn out, the Saw will not operate. The Carbon  
Brush should be replaced by a qualified technician. The Carbon Brush can be  
accessed for evaluation or replacement by a qualified technician, by removing the  
Brush Holder (44) atop the Left and Right Body (49 and 50).
