Rotary Hammer Safety
A rotary hammer is a drill that is used to drill through concrete. It should not be confused with the hammer drill. The hammer drill moves the bit in and out directly. The rotary hammer uses a piston to increase the force of each blow.
SAFETY EQUIPMENT WHEN USING A ROTARY HAMMER DRILL
Always wear protective eyewear, hearing protection, and protective gloves when using a rotary hammer. A dust mask is necessary when you drill through concrete or other dust producing material. A full-face shield is better than safety goggles alone.
PLAN AHEAD
THE RIGHT WAY TO USE A ROTARY HAMMER SAFELY
- Use the right power of rotary hammer for the job. Always read the manufacturer’s guide before using an unfamiliar rotary hammer.
- Plan your drilling before you start. Check both sides of your drilling area before drilling. Place hazard fences around every area where debris may fall. Identify any hidden gas pipes or electrical cables with a pipe or cable locator.
- Do not use a rotary hammer in any environment where fuel fumes could have concentrated. The rotary hammer drill armature produces sparks.
- Do not use a rotary hammer on ladders and other unstable surfaces. Always use a proper scaffold or work platform for elevated work.
SAFE USE
Check all cables and plugs before you plug in the rotary hammer. Always use the correct plug for the available electrical supply. Keep your extension cords short to reduce voltage drop. Repair or replace any cords that are frayed.
Use a residual current device with 240-volt rotary hammers. The RCD will automatically disconnect the power if it detects a short circuit. Test the RCD each time before you start.
You should hold the rotary hammer firmly in both hands at all times. Adjust the stabilizer and side handle for a comfortable working position. Drilling from a standing position will give you more control in case the drill bit binds.
Do not try to enlarge an existing hole. Use the right drill bit the first time. Disconnect the rotary hammer before you change the drill bit.
If the drill bit binds, you should stop the rotary hammer immediately and disconnect it. Then unwind the rotary hammer drill bit by hand. Do not try to force it.
Remove the drill bit from the hole regularly to clear out dust and debris. This helps to prevent binding. Check the air vents on the rotary hammer each time you do this. Remove the accumulated rubble or debris after you finish, or at the end of every work day.
