Compound Miter Saw Safety

Specific safety instructions for this compound miter saw
1. Do not operate the miter saw until it is completely assembled and installed according to these
instructions.
2. If you are not thoroughly familiar with the operation of miter saws, seek guidance from your
supervisor, instructor or other qualified person.
3. Always hold the work firmly against the fence and table.
4. Do not perform any operation free hand (use clamp wherever possible).
5. Keep hands out of the path of the saw blade. If the workpiece you are cutting would cause your
hands to be within 8-3/4 in. of the saw blade, the workpiece should be clamped in place before making the cut.
6. Be sure the blade is sharp, runs freely and is free of vibratio n.
7. Allow the motor to come up to full speed before starting a cut.
8. Keep the motor air slots clean and free of chips or dust.
9. Always m ake sure all handles are tight befor e cutting, even if the table is position ed in one of the
positive stops.
10. Be sure both the blade and the collar are clean and the arbor bolt is tightened securely.
11. Use only blade collars specified for your saw.
12. Never use blades larger in diameter than 12 inches.
13. Never apply lubricants to the blade when it is running.
14. Al wa ys check the blade for crack s or dam age bef ore oper ati on. R ep lace a c r acked or damaged blade
immediately.
15. Never use blades recommended for operation at less than 4200 RPM.
16. Always keep the blade guards in place and use at all times.
17. Never reach around the saw blade.
18. Make sure the blade is not contacting the workpiece before the switch is turned ON.
19. Impor tant: After com pleting the cut, r elease the trigger and wait for the blade t o stop before ret urning

Electrical

Extension Cords
Power Supply and Motor Specifications
The AC motor used in this saw is a universal, nonreversible type (see Motor in the Specifica- tions section on page 8).
To avoid electrical hazards, fire hazards, or damag e to the machine, use proper circuit protection. Your saw is wired at the factory for 120V o peration. Connect to a 120V, 15 Amp circuit and use a 15 amp time delay fuse or circuit brea ker. If p ower co rd is worn or cut, or damaged in any way, have it replaced immediately to avoid shock or fire.
Electrical Requirements
This machine is double insulated to provide a double thicknes s of insulation between the user and the machine's electr ica l system . All expos ed metal parts are isolated from the internal m etal motor components with protective insulation.
This saw has a plug that looks like the one shown in Figure A.
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 machine wil l draw. An undersized cord will cause a drop in the line voltage resulting in power loss and overheating. The table below shows the correct size to use depending on the cord length and nameplate ampere rating. If in d oubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.
Cord Length AWG 00 – 25ft 016 25 – 50ft 014
Important: Make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.
Figure A
To reduce the risk of electrical shock, this saw has a polarized plug (o ne b lad e is wider th an th e other). This plug will f it in a polarized outlet onl y one way; if the plug does not fit fully in the outlet, reverse the plug. If it stil l does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
Double insulation does not take the place of normal safety precautions when operating this tool.
To avoid electrocution:
1. Use only identical replacement parts when
servicing a tool with double insulation. Servicing should be perf orm ed by a qualified technician.
2. Do not use power tools in wet or damp
locations or expose them to rain or snow.

3. While holding the upper arm in position, turn the
stop knob (B) until it touches the stop plate (A). Note: Stop plate (A) must be flipped to the left.
4. Cut two parallel grooves.

Auxiliary Wood Fence

When making m ultiple or repetitive cuts t hat result in cut-off pieces of one inc h or les s, it is pos s ible f or the saw blade to catch th e c ut-of f piece and throw it out of the saw or into the bl ade guard a nd housi ng, possibly causing damage or injury. To minimize this, an auxiliary wood fence can be mounted to your saw. Holes are provided in the saw fence to attach an auxiliary wood fence (this provides additional depth of cut). This fence should be constructed of straight wood approximately 3/4 in. thick by 1-1/2 in. high by 22 in. long. Attach the wood fence secure ly and mak e a full depth cut to make a blade slot. Check for interferenc e between the wood fence and the lower blad e guard . Adjust if necessary.

Cutting Base Molding

Crown Molding

Base moldings and many other moldings can be cut on a compound miter saw. The setup of the saw depends on molding characteristics and application. Per form prac tice cuts on s crap m ater ial to achieve best results:
1. Always make sure m oldings rest firmly agai nst fence and table. Use hold-do wn, cr o wn m olding vise or C-clamps, whenever possible, and place tape on the are a being clamped to a void marks.
2. Reduce splintering by tapi ng the cut area prior to making the cut. Mark the cut line directl y on the tape.
3. Splintering typically happens due to an incorrect blade applic ation and thinness of the material.
Note: Always perform a dry run cut so you can determine if the operation being attempted is possible before power is applied to the saw.
Your compound miter s aw is suited for the difficult task of cutting cro wn m oldi ng. To fit properly, cro wn molding must be compound-mitered with extreme accuracy. The two surfaces on a piece of crown molding that fit flat aga inst the ceiling and wall are at angles that, when added toget her, equal exactly
90°.
Most crown molding has a top rear angle (the section that fits flat agains t the ceiling) of 52°and a bottom rear angle (the section th at fits flat against the wall) of 38°.
In order to accurately cut c rown molding for a 90° inside or outside corner, lay the molding with its broad back surface at on the saw table.
When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one changes the other, as well.

Maintenance

Lower Blade Guard
To avoid injury while performing maintenance, always unplug the power cord before working on the saw. Failure to comply may cause serious injury!
Never use gasoline or any highly volatile solvents to clean the miter saw. Failure to comply may cause serious injury!
Use only replacement parts that are identical to the parts list at the end of this manual and reassemb le exactl y as the original assembly to avoid electrical shock. Failure to comply may cause serious injury!
Replacing Carbon Brushes
Replace both carbon brushes when either has less than 1/4 in. length of car bon remainin g, or if the spring or wire is damaged or burned.
To inspect or replace brushes:
1. Unplug the saw.
2. Remove the b lack plastic c ap on the s ide of
the motor Remove the cap cautiously, because it is
spring-loaded.
3. Pull out the brush and replace.
Do not use the saw without the lower blade guard. The lower blade gu ard 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.
When cleaning the lower guard, unplug the saw from the power source receptacle to avoid unexpected startup.
Do not use solvents on the
guard. They could m ake the plastic “ cloudy” and brittle.
Saw Dust
Periodically, saw dust will acc umulate under the work table and bas e. This could cause difficulty in the movement of the work table when setting up a miter cut. Frequently blow out or vacuum up the saw dust.
If blowing saw dust, wear proper eye protection to keep debris from entering eyes.
Lubrication
4. Reverse above steps to reassemble. Tighten the cap snugly, but do not over­tighten.
Replace the brush for the other side in th e sam e manner described above.
Note: To reinstall the sam e brushes, first make sure the brushes go back in the way they came out. This will avoid a break-in period that reduces motor performance and increases wear.
All the motor bearin gs in this tool are lubric ated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions; therefore, no further lubrication is required.
Lubricate the following as necessary: Chop pivot: Apply light machine oil. Central pivot of plastic guard: Use light
household oil (se wing machine oil) on metal-to­metal or metal-to-pl astic guard contact areas as required for smooth, quiet operation. Avoid excessive oil, to which saw dust will cling.
