Add lubricant without disconnecting the saw, then continue
Make a short test cut to see whether vibration releases it
3. You must use a portable electric tool in a damp outdoor area. Which setup best addresses the electrical hazard?
Wear rubber-coated gloves and connect through a standard indoor extension cord
Use any grounded tool as long as the ground prong is removed from the plug

Remove the guard to prevent it from catching on nearby objects
9. Grinding sparks would travel toward an open container of flammable solvent. What is the best action?
Continue if a fire extinguisher is placed within reach
Loosely cover the container so pressure cannot build up
Stop and eliminate or isolate the fire hazard, or move the work to a suitable location
Use a fan to redirect most of the sparks away from the container
10. You are preparing to cut a narrow board with a portable circular saw. How should the board be controlled?
Hold it down with your free hand several inches from the blade
Brace it with one foot so both hands can guide the saw
Ask another person to hold both ends during the cut

Change the speed setting and rock the saw until it releases
Release the trigger, unplug the saw, and verify that motion has stopped
Have another person hold the material while the saw remains powered
15. During a pre-use check, you find that a hammer's wooden handle is cracked near the head. What should you do?

Its rated speed is below the grinder's speed so it cuts less aggressively
It fits inside the guard, even if its intended material is different
