GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings and all instructions. Failure to follow the war i gs a d i structio s may result i electric shock, fire a d/or serious i jury.
SAVE A WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” i the war i gs refers to your mai s-operated (corded) power tool or battery-operated (cordless) power tool.
Work Area safety
1. Keep your work area clean and well lit. Cluttered or dark areas i vite accide ts.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
Power tools create sparks which ig ite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractio s ca cause you to lose co trol.

Electrical Safety (Continued)
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of a RCD reduces the risk of electric shock.
Personal Safety
1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use power tool while you are tired or under the influence of
drugs, alcohol, or medication. A mome t of i atte tio while operati g power tools may result i serious perso al i jury.
2. Use personal protective equipment. Always wear eye protection. Protective equipme t such as dust masks, o -skid safety shoes, hard hat, or heari g protec-
tio used for appropriate co ditio s will reduce perso al i jury.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.
Carryi g power tools with your fi ger o the switch or e ergizi g power tools that have the switch o i vites accide ts.
4. Remove any adjusting key or wrench before turning the power tool on. A wre ch or a key left attached to a rotati g part of the power tool may result i perso al
i jury.
5. Do not overreach. Keep proper footing and balance at all times. This e ables better co trol of the power tool i u expected situatio s.
6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or lo g hair ca
be caught i movi g parts.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collectio ca
reduce dust-related hazards.
8. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless actio ca cause severe
i jury withi a fractio of a seco d.
Power Tool Use and Care
1. Do not force the power tool. Use the correct power tool for your application. The correct tool will do the job better a d safer at the rate for which it was de-
sig ed.
2. Do not use the power tool if switch does not turn it on and off. A y power tool that ca ot be co trolled with the switch is da gerous a d must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing
power tool. Such preve tative safety measures reduce the risk of starti g the power tool accide tally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are da gerous i the ha ds of u trai ed users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation.
If damaged, have the power tool repaired before use. Ma y accide ts are caused by poorly mai tai ed power tools.
6. Keep cutting tools sharp and clean. Properly mai tai ed cutti g tools with sharp cutti g edges are less likely to bi d a d are easier to co trol.
7. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operatio s differe t from those i te ded could result i a hazardous situatio .
8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery ha dles a d graspi g surfaces do ot allow for safe ha dli g a d co trol
of the tool i u expected situatio s.
