For Your Own Safety Read Instruction Manual Before Operating Compound Saw Save it for future reference GENERAL SAFETY PRECAUTIONS (For All Tools) 1. KNOW YOUR POWER TOOL. Read the owner's manual carefully. Learn the tools applications and limitations, as well as the specific potential hazards peculiar t o it. 2. KEEP GUARDS IN PLACE and in working order. 3.REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on. 4.
16. EXTENSION CORDS. Make sure your extension cord is in good condition. When using an extension cord, be sure t o use one heavy enough t o carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet, etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY t o the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful t o the motor. ADDITIONAL SAFETY RULES 1. Wear eye protection. 2.
21. Shut off power and wait for saw blade t o stop before servicing or adjusting tool. 22. Be alert at all times, especially during repetitive, monotonous operations. Don't be lulled into a false sense of security. Blades are extremely unforgiving. 23. Do not cut cross-armed as shown in the picture. I 24. Always use accessories recommended in this manual. Use of improper accessories such as abrasive wheels may cause an injury. 25. Don't abuse cord. Never yank cord t o disconnect it from the receptacle.
Carrying tool When carrying the tool, lower the handle fully and press the stopper pin to lock the handle in the lowered position. Secure the turn base by means of the knob. Carry the tool by holding both side of the tool base. WARNING: Be sure that the tool is unplugged first Socket wrench The socket wrench is stored as shown in the figure. When using the socket wrench, pull it out of the wrench holder.
Press the shaft lock so that the blade cannot revolve and use the socket wrench to loosen the hex bolt clockwise.Then remove the hex bolt, outer flange and blade. To install the blade, mount the blade onto the spindle, making sure that the direction of the arrow on the surface of the blade matches the direction of the arrow on the blade case. Install the outer flange and hex bolt, and then use the socket wrench to tighten the hex bolt securely counterclockwise while pressing the shaft lock.
Dust bag The use-of the dust bag makes cutting operations clean and dust collections easy. To attach the dust bag, fit the bags entry port over the dust nozzle. I When the dust bag is about half full, remove the dust bag from the tool and pull the fastener out. Empty the dust bag of its contents, tapping it lightly so as to remove particles adhering to the insides which might hamper further collection.
Positioning kerf boards This tool is provided with kerf boards in the turn base. The kerf boards are factory-adjusted so that the saw blade does not contact the kerf boards. Before use, adjust the kerf boards as follows: First unplug the tool. Loosen the all screws (2 each on left and right) which secure the kerf boards. Retighten them to the extent that the kerf boards can be easily moved by hand. Lower the handle fully and press the stopper pin to lock the handle in the lowered position.
Maintaining maximum cutting capacity ' Unplug the tool before any adjustment is attempted. This tool is factory adjusted to provide the max. cutting capacity for a 305 mm (12") saw blade. When the diameter of the blade has been reduced due to sharpening, adjust the depth adjusting bolt by turning it with the socket wrench. The saw blade is lowered by turning the depth adjusting bolt counterclockwise and raised by turning it clockwise.
Positioning for adjusting the bevel angle The saw blade tilts up to 45" to the left. To adjust the bevel angle, loosen the lever at the rear of the tool. Tilt the blade to the left so that the pointer indicates the desired angle on the bevel scale. Then tighten the lever firmly to secure the arm. CAUTION: When tilting the saw blade, be sure to raisl he handle fullv. Securing workpiece Whenever possible, secure the workpiece with the optional vise.
2. Horizontal vise (optional accessory) Vise plate The horizontal vise can be installed in I two positions on either the left or right side of the base. When performing 15" or greater miter cuts, install the horizontal vise on the side opposite the direction in which the turn table is to be turned. By flipping the vise nut to the left, the vise is released, and rapidly moves in and out.
Operation CAUTION: *Before use, be sure to release the handle from the lowered position by pulling the stopper pin. *Make sure the blade is not contacting the workpiece, etc. before the switch is turned on. *Do not apply excessive pressure on the handle when cutting. Too much force may result in overload of the motor and/or decreased cutting efficiency. *Gently press down the handle to perform the cut.
*Loosen the lever and tilt the Saw blade to set the bevel angle. Be sure to retighten the lever firmly to secure the selected bevel angle safely. Secure the workpiece. Switch on the tool and wait until the blade attains full speed. Then gently lower the handle to the fully lowered position while applying pressure in the direction of the arrow (in parallel with the blade).
3. Compound cutting Compound cutting can be performedat angles shown in the table below. Bevel angle 45O 1 I Miter angle Left and right ' 0 - 45" When performing the compound cutting, refer to "Miter cutting" and "Bevel cut" explanations. 4.

side of the blade with the top surface of the turn base using the triangular rule, try-square, etc. by turning the hex bolt (A) clockwise. Then tighten the lever securely. Make sure that the pointer on the turn base indicates 0" on the bevel scale on the arm . If the pointer does not indicate 0", loosen the screw securing the pointer and adjust the pointer. b) 45' bevel angle Adjust 45" bevel angle after performing 0" bevel angle adjustment.
Replacing carbon brushes Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. I -Limit mark Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.
