TABLE OF CONTENTS Introduction ...................................................................................................................................................................... 2 General Safety Rules .....................................................................................................................................................3-4 Specific Safety Rules...............................................................................................................
GENERAL SAFETY RULES Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times.
GENERAL SAFETY RULES When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury. SERVICE Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury. SPECIFIC SAFETY RULES DANGER! Keep hands away from cutting area and blade.
SPECIFIC SAFETY RULES Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. A wire gage size (A.W.G.) of at least 12 is recommended for an extension cord 50 feet or less in length. A cord exceeding 50 feet is not recommended. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
SYMBOLS Some of the following symbols may be used on this tool. Please study them and learn their meaning. Proper interpretation of these symbols will allow you to operate the tool better and safer.
SYMBOLS The following signal words and meanings are intended to explain the levels of risk associated with this product. SYMBOL SIGNAL MEANING DANGER: Indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury. WARNING: Indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury. CAUTION: Indicates a potentially hazardous situation, which, if not avoided, may result in minor or moderate injury.
ELECTRICAL DOUBLE INSULATION When working outdoors with a tool, use an extension cord that is designed for outside use. This type of cord is designated with “WA” on the cord’s jacket. Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

ASSEMBLY WARNING: Do not connect the tool to a power supply until all assembly is complete. Failure to comply could result in accidental starting and possible serious injury. SPINDLE OUTER FLANGE WASHER WARNING: 7-1/4 in. (184 mm) blade is the maximum blade capacity of the saw. Also, never use a blade that is too thick to allow outer flange washer to engage with the flat on the spindle.
ASSEMBLY REMOVING BLADE See Figure 3. Unplug the saw. CAUTION: To prevent damage to the spindle or spindle lock, always allow motor to come to a complete stop before engaging spindle lock. Depress spindle lock button. Remove blade screw by turning it clockwise with the hex wrench. Remove spring washer. SPINDLE LOCK BUTTON WRENCH Remove outer flange washer. Lift lower blade guard.

OPERATION WARNING: Do not allow familiarity with the tool to make you careless. Remember that a careless fraction of a second is sufficient to inflict severe injury. APPLICATIONS You may use this saw for the following purposes: Cutting all types of wood products (lumber, plywood, paneling) NOTE: The use of abrasive cut-off wheels is not recommended for this saw.
OPERATION KICKBACK See Figures 5, 6, 7, and 8. Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action which pinches the blade in the wood. See Figure 5. DANGER: Release switch immediately if blade binds or saw stalls. Kickback could cause you to lose control of the saw. Loss of control can lead to serious injury. Fig. 5 To guard against kickback, avoid dangerous practices such as the following. Setting blade depth incorrectly.
OPERATION STARTING/STOPPING THE SAW SWITCH TRIGGER See Figure 9. To start the saw: Depress the switch trigger. Always let the blade reach full speed, then guide the saw into the workpiece. WARNING: The blade coming in contact with the workpiece before it reaches full speed could cause the saw to “kickback” towards you resulting in serious injury. To stop the saw: Release the switch trigger. After you release the switch trigger, allow the blade to come to a complete stop.
OPERATION OPERATING THE SAW See Figures 11, 12, and 13. It is important to understand the correct method for operating the saw. Refer to the figures in this section to learn the correct and incorrect ways for handling the saw. WARNING: To make sawing easier and safer, always maintain proper control of the saw. Loss of control could cause an accident resulting in possible serious injury. DANGER: Fig.
OPERATION CROSS CUTTING See Figure 14. When making a cross cut, align the line of cut with the full length kerf indicator on the base. Since blade thicknesses vary, always make a trial cut in scrap material along a guideline to determine how much, if any, you must offset the guideline to produce an accurate cut. NOTE: The distance from the line of cut to the guideline is the amount you should offset the guide. BEVEL CUTTING The base of the saw may be adjusted for bevel cuts up to 51.5°.
OPERATION TO ADJUST 0° BEVEL STOP See Figures 16 and 17. BEVEL ADJUSTMENT LEVER Unplug the saw. Pull bevel adjustment lever upward to release. Turn set screw with hex wrench and adjust base until it is square with the saw blade. Securely lock the bevel adjustment lever. TO ADJUST BEVEL SETTING See Figure 16. Unplug the saw. Pull the bevel adjustment lever upward until the motor housing moves freely.
OPERATION TO BEVEL CUT See Figure 18. WARNING: Attempting a bevel cut without having the bevel adjustment lever securely locked in place can result in serious injury. Hold the saw firmly with both hands as shown. Rest the front edge of the base on the workpiece. Start the saw and let the blade reach full speed. Guide the saw into the workpiece and make the cut. Release the trigger and allow the blade to come to a complete stop. Lift the saw from the workpiece.
OPERATION LENGTH OF CUT SCALE LENGTH OF CUT SCALE See Figure 20. The saw is equipped with a length of cut scale on its base. It is parallel with the saw blade and you can use it to measure the distance the blade cuts into the material. NOTE: Six inches is the maximum length of cut that you can measure. Also, it is accurate only when the depth of cut is set at full maximum depth. Fig. 20 ADJUSTMENTS ADJUSTING THE LEVER LOCK MECHANISM See Figure 21.
MAINTENANCE WARNING: Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommended using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.
MAINTENANCE LUBRICATION See Figure 22. This tool has been properly lubricated and is ready to use. It is recommended that the gears be lubricated only with Mobil SHC 636 Oil. After extended use, check the oil level, using the dipstick provided. DIPSTICK CHECKING THE OIL Unplug the tool. Place the base of the saw on a horizontal surface. Remove the oil plug using a 6mm hex wrench. �Insert the dipstick straight into the tool. Do not force. �Check the oil level.
