GENERAL SAFETY RULES
POWER TOOL USE AND CARE
1. Avoid accidental start-ups. Make sure the power switch is in the OFF position before connecting the plug to a
power source or carrying the tool.
2. Check power tool for damaged parts. Check for misalignment of moving parts, jamming, breakage, improper
mounting, or any other conditions that may affect the tool’s operation. Do not use the power tool if the switch does
not turn ON/OFF. Any part that is damaged should be properly repaired or replaced before use.
3. Do not force the tool to do a job for which it was not designed. Use the correct power tool and accessories and
follow the instructions for your application to prevent hazardous situations.
4. Remove adjustment tools. Always make sure all adjustment tools or wrenches are removed from the tool before
turning on the power tool.
5. Keep guards in place and in working order before operating the tool. All protection and safety devices must be
in place after completing repair and maintenance procedures.
6. Never leave a running tool unattended. Do not leave the tool until it has come to a complete stop.
POWER TOOL MAINTENANCE
1. Always disconnect the power cord plug from the electrical outlet when making adjustments, changing parts, or
storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
2. Maintain power tools properly. Safely store power tools out of the reach of children. Always keep tools clean and
in good working order. Follow instructions for lubricating and changing accessories.
3. Only have your power tool serviced by a qualified repair person using only identical replacement parts. Use of
any other part can cause personal injury and damage to the tool.
