DeWalt DW938 Troubleshooting

"When the trigger is pulled, nothing happens."

The battery may not be charged. Plug your battery into the battery charger. Wait as advised by the instruction manual, and reconnect the battery.

First ensure that the battery charger is plugged into a power source. The battery charger will have instructions for the user to review the current state of the charger. This will be shown through use of lights with correlating labels. Look over these lights, and if none are present consider purchasing a new battery charger.

The trigger safety is located just above the trigger. A red stripe should be visible if the trigger safety is released. If the trigger cannot move and the trigger safety has been checked, consider reviewing the integrity of the safety.

If the previous troubleshooting instructions fail move on to opening the saw (covered in the breakdown report). The motor should move if powered by the original input of 18 volts.

If the blade does not stay in the blade holder first be sure that the blade is being installed correctly. The blade will lock into place via the movement of a yellow arm which will collapse into the saw casing when locked. If this does not lock the blade into place consider purchasing a new blade holder.

If the blade is stuck inside of the blade holder review the previous bullet point in the troubleshooting page. The mentioned yellow arm should be released. When released this arm sticks out from the saw casing. If this arm will not release try to pry it away with a flat instrument such as a screwdriver—use caution. If the arm will not release or this arm does not help with releasing the blade from the holder move on to opening the saw.

If the saw blade does not cut see to it that the blade is sharp. Put a fresh blade in the blade holder and see if this improves the saw’s cutting ability.
