Study Notes
Electrical Tools
- Operated by electricity, using either alternating (AC) or direct current (DC) sources.
- Examples include belt sanders and circular saws.
Pneumatic Tools
- Powered by compressed air from gasoline or electric compressors.
- Common examples are air hammers and pneumatic nailers.
Hydraulic Tools
- Utilizes fluid pressure produced by hand or electric pumps.
- Typical tools include pipe benders, jackhammers, and Porta-Powers.
Electric Grill Safety
- Use double-insulated electrical power tools with ground fault protection to mitigate electric shock risks.
- Ground fault circuit interrupter (GFCI) devices enhance safety by preventing electrical current flow during faults.
- Ensure drill bits are securely tightened and keep the drill’s air vent clear to maintain safety and performance.
Pneumatic Drills
- Operate using compressed air fed through an air hose.
- Similar in components and uses to electric drills, ideal for environments without electricity.
Circular Saws
- Feature a rigid plastic guard to protect users from debris and the spinning blade.
Saber Saws (Jig Saws)
- Equipped with fine blades, ideal for delicate tasks, including intricate cuts in wood and soft metals.
Safety Checklist
- Always ensure the switch of power tools, such as saws, is in the OFF position before plugging into an outlet.
Power Miter Saw
- Combines the functions of a miter box with a circular saw for making straight and miter cuts.
Angle Grinders
- Known as side grinders, these tools are designed for grinding hard materials and surfaces, including pipes and welds.
Bench Grinders
- Must use adjustable tool rests for support while grinding, with a maximum gap of 1/8 inch from the tool rest to the wheel.
Pneumatically Powered Nailer
- Important to read the manufacturer's instructions prior to use.
- Incorporate maintenance steps such as adding oil to the air inlet before operation.
- Always disconnect the air hose before attempting repairs if the nailer malfunctions.
Air Impact Wrench
- Ensure body stance is balanced when using to maintain control and safety.
