English
As you finish a cut, release the trigger and allow the blade to stop before lifting the saw from the work. As you lift the saw, the spring- tensioned telescoping guard will automatically close under the blade. Remember the blade is exposed until this occurs. Never reach under the work for any reason. When you have to retract the telescoping guard manually (as is necessary for starting pocket cuts) always use the retracting lever.
NOTE: When cutting thin strips, be careful to ensure that small cutoff pieces don’t hang up on inside of lower guard.
RIPPING (FIG. 17) | FIG. 17 |
Ripping is the process of cutting wider boards into narrower strips – cutting grain lengthwise. Hand guiding is more difficult for this type of sawing and the use of DEWALT DW3278 rip guide
(W) is recommended.
POCKET CUTTING (FIG. 18) |
|
WARNING: Never tie the | W |
blade guard in a raised position. | |
Never move the saw backwards | FIG. 18 |
when pocket cutting. This may |
|
cause the unit to raise up off the |
|
work surface which could cause |
|
injury. |
|
A pocket cut is one that is made in |
|
a floor, wall or other flat surface. |
|
1. Adjust the saw foot plate so the |
|
blade cuts at desired depth. | E |
|
2. Tilt the saw forward and rest front of the foot plate on material to be cut.
3.Using the lower guard lever, retract lower blade guard to an upward position. Lower rear of foot plate until blade teeth almost touch cutting line.
4.Release the blade guard (its contact with the work will keep it in position to open freely as you start the cut). Remove hand from guard lever and firmly grip auxiliary handle (E), as shown in Figure 18. Position your body and arm to allow you to resist kickback if it occurs.
5.Make sure blade is not in contact with cutting surface before starting saw.
6.Start the motor and gradually lower the saw until its foot plate rests flat on the material to be cut. Advance saw along the cutting line until cut is completed.
7.Release trigger and allow blade to stop completely before withdrawing the blade from the material.
8.When starting each new cut, repeat as above.
Kickback
When the saw blade becomes pinched or twisted in the cut, kickback can occur. The saw is thrust rapidly back toward the operator. When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit backward. When the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is more likely to occur when any of the following conditions exist.
1.IMPROPER WORKPIECE SUPPORT
A.Sagging or improper lifting of the cut off piece can cause pinching of the blade and lead to kickback (Fig. 14).
