Cutting Plastic Pipe or Other Round Material
Plastic pipe can be easily cut with your saw. It should be cut just like wood and ClaMpED oR
HElD FIRMlY To THE FENCE To KEEp IT FRoM RollING. This is extremely important when
making angle cuts.
Cutting Large Material (Fig. Z)
Occasionally you will encounter a piece of wood a little too large to fit beneath the lower guard.
If this occurs, simply place your right thumb on the upper side of the guard and roll the guard up
just enough to clear the workpiece, as shown in Figure Z. Avoid doing this as much as possible,
but if need be, the saw will operate properly and make the bigger cut. NEVER TIE, TAPE, OR
OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS SAW.

MAINTENANCE


WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect
it from power source before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can cause injury.

WARNING: To reduce the risk of serious personal injury, DO NOT touch the sharp
points on the blade with fingers or hands while performing any maintenance.
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic
guard. The polycarbonate material used in the guard is subject to attack by certain chemicals.
1. All bearings are sealed. They are lubricated for life and need no further maintenance.
2. Periodically clean all dust and wood chips from around AND UNDER the base and the
rotary table. Even though slots are provided to allow debris to pass through, some dust
will accumulate.
3. The brushes are designed to give you several years of use. To replace the brushes return the
tool to the nearest service center for repair. A list of service center locations is packed with
your tool.
Removing and Replacing Belt (Fig. AA)
The belt is designed to last the life of the tool. However, abuse of the tool could cause the belt
to fail.
If the blade does not turn when the motor is running, the belt has failed. To inspect or replace the
belt, remove the belt cover screws. Remove the belt cover. Inspect the ribs of the belt for wear or
failure. Check belt tension by squeezing the belt as shown in Figure AA. The belt halves should almost
touch when squeezing firmly with the thumb and index finger. To adjust the tension, loosen, but do
not remove, the four crosshead screws

Worklight Cleaning
For the best worklight performance, perform the following maintenance regularly.
1. Carefully clean sawdust and debris from worklight lens with a cotton swab.
2. DO NOT use solvents of any kind, they may damage the lens.
3. Dust build-up can block the worklight and prevent it from accurately indicating the line
of cut.
4. Follow miter saw's instruction manual to remove and install blade.
5. With blade removed from saw, clean pitch and build-up from blade. Pitch and debris can
interfere with the worklight and prevent it from accurately indicating the line of cut.

Dust Duct Cleaning
Depending on your cutting environment, saw dust can clog the dust duct and may prevent dust
from flowing away from the cutting area properly. With the saw unplugged and the saw head
raised fully, low pressure air or a large diameter dowel rod can be used to clear the dust out of the
dust duct.
Cleaning

WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a
week. To minimize the risk of eye injury, always wear approved eye protection when
performing this procedure.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals may weaken the plastic materials used in these parts. Use a
