Electrical Requirements And Safety

Grounding Instructions

In The Event Of A Malfunction Or

BREAKDOWN, grounding provides a path of least resistance for electric currents and reduces the risk of electric shock. This tool is equipped with an electrical cord that has an equipment- grounding conductor and a grounding plug. The plug must be plugged into a matching receptacle that is properly installed and grounded in accordance with all local codes and ordinances.

Do Not Modify The Plug Provided.

If it will not ﬁt the receptacle, have the proper receptacle installed by a qualiﬁed electrician. IMPROPER CONNECTION of the equipment grounding conductor can result in risk of electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electrical cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal. CHECK with a qualiﬁed electrician or service person if you do not completely understand the grounding instructions, or if you are not certain the tool is properly grounded. USE only three-wire extension cords that have three-pronged grounding plugs with three-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cords immediately.

Guidelines For Extension

Cords

USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Use an extension cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power, overheating and burning out of the motor. The table on the right shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualiﬁed technician before using it. Protect your extension cords from sharp objects, excessive heat and damp or wet areas. Use a separate electrical circuit for your tool. This circuit must not be less than #12 wire with a 20 A time-lag fuse or a #14 wire with a 15 A time-lag fuse. NOTE: When using an extension cord on a circuit with a #14 wire, the extension cord must not exceed 25 feet in length. Before connecting the motor to the power line, make sure the switch is in the off position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor. This tool is intended for use on a circuit that has a receptacle like the one illustrated in Fig. 1. Fig. 1 shows a three-pronged electrical plug and receptacle that has a grounding conductor. If a properly grounded receptacle is not available, an adapter (Fig. 2) can be used to temporarily connect this plug to a two-contact grounded receptacle. The adapter (Fig. 2) has a rigid lug extending from it that MUST be connected to a permanent earth ground, such as a properly grounded receptacle box. In all cases, make certain the receptacle is properly grounded. If you are not sure, have a qualiﬁed electrician check the receptacle. This tool is for indoor use only. Do not expose to rain or use in damp locations.

● Disconnect the miter saw. To avoid injury from accidental starting, unplug the saw before any adjustments, including set-up and blade changes. ● Compare the direction of rotation arrow on the guard to the direction arrow on the blade. The blade teeth should always point downward at the front of the saw. ● Tighten the arbor bolt. ● Tighten the cover plate screw. ● Check for damaged parts. Check for: ● Alignment of moving parts ● Damaged electric cords ● Binding of moving parts ● Mounting holes ● Function of arm return spring and lower guard: Push the cutting arm all the way down, then let it rise until it stops. The lower guard should fully close. Follow instructions in TROUBLESHOOTING GUIDE for adjustment if necessary. ● Other conditions that may affect the way the miter saw works. ● Keep all guards in place, in working order and proper adjustment. If any part of this miter saw is missing, bent, damaged or broken in any way, or any electrical parts don’t work, turn the saw off and unplug it. ● Replace bent, damaged, missing or defective parts before using the saw again. ● Maintain tools with care. Keep the miter saw clean for best and safest performance. Follow instructions for lubricating. Do not put lubricants on the blade while it is spinning. ● Remove adjusting wrench from the tool before turning it on. ● To avoid injury from jams, slips, or thrown pieces, use only recommended accessories. ● Check the dust bag before you work. Empty the bag if it is more than half-full.

Recommended Accessories

● Consult the ACCESSORIES and ATTACHMENTS section of this Operators Manual for recommended accessories. Follow the instructions that come with the accessory. The use of improper accessories may cause risk of injury to persons. ● Choose the correct 10 in. diameter blade for the material and the type of cutting you plan to do. Do not use thin kerf blades. ● Make sure the blade is sharp, undamaged and properly aligned. With the saw unplugged, push the cutting arm all the way down. Manually spin the blade and check for clearance. Tilt the power-head to a 45° bevel and repeat the test. ● Make sure the blade and arbor collars are clean. ● Make sure all clamps and locks are tight and there is no excessive play in any parts.

Keep Your Work Area Clean

Cluttered areas and benches invite accidents. To avoid burns or other ﬁre damage, never use use the miter saw near ﬂammable liquids, vapors, or gases. ● Plan ahead to protect your eyes, hands, face and ears. ● Know your miter saw. Read and understand this Operator’s Manual and labels afﬁxed to this tool. Learn its application and limitations as well as the speciﬁc potential hazards peculiar to this tool.

Warning

Page 19

Plan Your Work

● Use the right tool. Don’t force a tool or attachment to do a job it was not designed to do. Use a different tool for any workpiece that can’t be held in a solidly braced, ﬁxed position. This machine is not designed for cutting masonry, masonry products, ferrous metals (steel, iron, and iron-based metals.) Use this miter saw to cut only wood, wood- like products, or non-ferrous metals. Other material may shatter, bind the blade, or create other dangers. Remove all nails that may be in the workpiece to prevent sparking that could cause a ﬁre. Remove dust bag when cutting non-ferrous metals.

Dress For Safety

Any power tool can throw foreign objects into the eyes. This can result in permanent eye damage. Everyday eyeglasses have only impact resistant lenses and are not safety glasses. Glasses or goggles not in compliance with ANSI Z87.1 could seriously injure you when they break. ● Do not wear loose clothing, gloves, neckties or jewelry (rings, watches). They can get caught and draw you into moving parts. ● Wear non-slip footwear. ● Tie back long hair. ● Roll long sleeves above the elbow. ● Noise levels vary widely. To avoid possible hearing damage, wear ear plugs when using any miter saw. ● For dusty operations, wear a dust mask along with safety goggles.

Inspect Your Workpiece

Make sure there are no nails or foreign objects in the part of the workpiece being cut. Plan your work to avoid small pieces that may bind, or that are too small to clamp and get a solid grasp on. Plan the way you will grasp the workpiece from start to ﬁnish. Avoid awkward operations and hand positions. A sudden slip could cause your ﬁngers or hand to move into the blade.

Do Not Over-Reach

Keep good footing and balance. Keep your face and body to one side, out of the line of a possible kickback. NEVER stand in the line of the blade. Never cut freehand: ● Brace your workpiece ﬁrmly against the fence and table stop so it will not rock or twist during the cut. ● Make sure there is no debris between the workpiece and the table or fence. ● Make sure there are no gaps between the workpiece, fence and table that will let the workpiece shift after it is cut. ● Keep the cut off piece free to move sideways after it is cut off. Otherwise, it could get wedged against the blade and thrown violently. ● Only the workpiece should be on the saw table. ● Secure work. Use clamps or a vise to help hold the work when it’s practical.

Use Extra Caution With Large Or Odd

Shaped Workpieces.

● Use extra supports (tables, sawhorses, blocks, etc.) for workpieces large enough to tip. ● Never use another person as a substitute for a table extension, or as an additional support for a workpiece that is longer or wider than the basic miter saw table, or to help feed, support, or pull the workpiece. ● Do not use this saw to cut small pieces. If the workpiece being cut would cause your hand or ﬁngers to be within 6-3/4 inches of the saw blade the workpiece is too small. Keep hands and ﬁngers out of the “no hands zone” area marked on the saw table. ● When cutting odd shaped workpieces, plan your work so it will not bind in the blade and cause possible injury. Molding, for example, must lie ﬂat or be held by a ﬁxture or jig that will not let it move when cut. ● Properly support round material such as dowel rods, or tubing, which have a tendency to roll when cut, causing the blade to “bite”. To avoid injury, follow all applicable safety instructions, when cutting non-ferrous metals: ● Use only saw blades speciﬁcally recommended for non-ferrous metal cutting. ● Do not cut metal workpieces that must be hand held. Clamp workpieces securely. ● Cut non-ferrous metals only if you are under the supervision of an experienced person and the dust bag has been removed from the saw.

When Saw Is Running

Do not allow familiarity from frequent use of your miter saw to result in a careless mistake. A careless fraction of a second is enough to cause a severe injury. Before cutting, if the saw makes an unfamiliar noise or vibrates, stop immediately. Turn the saw OFF. Unplug the saw. Do not restart until ﬁnding and correcting the problem.

Warning

Turning Saw On (Fig. T)

To reduce the likelihood of accidental starting, a thumb activated lock-OFF switch is located on top of the switch handle. The lock-OFF switch (1) must be pushed in before the trigger switch (2) can be activated and the miter saw started. Make the switch child-proof. Insert a padlock through the hole (3) in the trigger switch and lock it. This will prevent children and other unauthorized users from engaging the trigger switch ON. Fig. T

Before Leaving The Saw

● Never leave tool running unattended. Turn power OFF. Wait for all moving parts to stop and unplug unit from power source. ● Make workshop child- proof. Lock the shop. Disconnect master switches. Store tool away from children and other unqualiﬁed users.

Body And Hand Position (Fig. S)

Never place hands near the cutting area. Proper positioning of your body and hands when operating the miter saw will make cutting easier and safer. Keep children away. Keep all visitors at a safe distance from the miter saw. Make sure bystanders are clear of the saw and workpiece. Don’t force the saw. It will do the job better and safer at its designed rate. Starting a cut: ● Place hands at least 6-3/4 in. away from the path of the blade – out of the “no-hands zone” (1). (Fig. S) ● Hold workpiece ﬁrmly against the fence to prevent movement toward the blade. ● With the power switch OFF, bring the saw blade down to the workpiece to see the cutting path of the blade. ● Press in lock-off switch in trigger switch handle. ● Squeeze trigger switch to start saw. ● Lower blade into workpiece with a ﬁrm downward motion. Finishing a cut: ● Hold the cutting arm in the down position. ● Release trigger switch and wait for all moving parts to stop before moving your hands and raising the cutting arm. ● If the blade doesn’t stop within 6 seconds, unplug the saw and follow the instructions in TROUBLESHOOTING GUIDE section.

Maintenance

To avoid injury, never put lubricants on the blade while it is spinning. To avoid ﬁre or toxic reaction, never use gasoline, naphtha acetone, lacquer thinner or similar highly volatile solvents to clean the miter saw. To avoid injury from unexpected starting or electrical shock, unplug the power cord before working on the saw. For your safety, this saw is double-insulated. To avoid electrical shock, ﬁre or injury, use only parts identical to those identiﬁed in the parts list. Reassemble exactly as the original assembly to avoid electrical shock.

Replacing Carbon Brushes (Fig. Bb)

Replace both carbon brushes when either has less than 1/4 in. length of carbon remaining, or if the spring or wire is damaged or burned. To inspect or replace brushes, ﬁrst unplug the saw. Then remove the black plastic cap (1) on the side of the motor (2). Remove the cap cautiously, because it is springloaded. Then pull out the brush and replace. Replace for the other side. To reassemble reverse the procedure. The ears on the metal end of the assembly go in the same hole the carbon part ﬁts into. Tighten the cap snugly, but do not overtighten. NOTE: To reinstall the same brushes, ﬁrst make sure the brushes go back in exactly the way they came out. This will avoid a break-in period that reduces motor performance and increases wear. Fig. BB

Lower Blade Guard

Do not use the saw without the lower blade guard. The lower blade guard is attached to the saw for your protection. Should the lower guard become damaged, do not use the saw until the damaged guard has been replaced. Develop a regular check to make sure the lower guard is working properly. Clean the lower guard of any dust or buildup with a damp cloth. CAUTION: Do not use solvents on the guard. They could make the plastic “cloudy” and brittle. When cleaning the lower guard, unplug the saw from the power source receptacle to avoid unexpected startup.

Emptying Sawdust Bag

Periodically, sawdust will accumulate under the work table and base. This could cause difﬁculty in the movement of the worktable when setting up a miter cut. Frequently blow out or vacuum up the sawdust. If blowing sawdust, wear proper eye protection to keep debris from blowing into eyes.

Lubrication (Fig. Cc)

All the motor bearings in this tool are lubricated with a sufﬁcient amount of high grade lubricant for the life of the unit under normal operating conditions; therefore, no further bearing lubrication is required. Lubricate the following as necessary: Chop pivot: Apply light machine oil to points indicated in illustration. Chop and Central pivot: Apply light machine oil to points indicated in illustration.
