· Whenever possible, the saw shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and will minimize damage to the blade’s teeth. Not keeping the foot of the saw in contact with the material being cut is the number one reason for ineffective reciprocating saw cutting at crash scenes.

· Do not force the tool or bind the blade. This diminishes battery life on cordless reciprocating saws. Create a rocking action by moving the body of the saw up and down as you cut while the foot remains in contact with the material being cut. Maintain the appropriate pressure against the material for the most effective cutting action.

· Protect yourself and your patient during the operation of the saw. Rescue personnel should don appropriate personal protective equipment (PPE), including safety glasses or goggles. Patients should have "hard" protection such as a KED or XP-1 immobilization board placed between them and the cutting blade.

· Blades are hot immediately after operation. Do not grab a used blade by the working end. Open the blade clamp and allow the blade to fall out of the end. Burns on fingertips are painful!

· Avoid accidental saw starting. Be sure the safety switch is in the locked position before making adjustments to the tool, inserting a fresh battery pack or changing the saw blade. Store your saw with the safety in the "locked" or "on" position.

· Do not operate a corded or cordless power tool in an explosive atmosphere. Power tools create sparks internally and externally, which may ignite dust or flammable vapors present in the area.

· For teams working with the newer generation of cordless reciprocating saws, remember to protect the exposed battery terminals from contacting any metal objects such as nails or screws. Metal across the terminals will short the battery out and may cause sparks, burns or a battery fire.
