Using
the Jackhammer Safely |
|
Lance Fluegel, and Bradley

- Read the operator's
instruction manual before using the tool.
- Be sure electric
models with a three-wire system are properly grounded, to reduce the
risk of fire and electric shock. This is not necessary for double insulated
models. Use a ground fault interrupter (GFI) for maximum safety protection.
- Be sure the extension
cord for electric models is a size large enough for the distance from
the receptacle to tool.
- On engine-driven,
air models always fill the gas tank out of doors with engine shut off
and cool. Never handle fuel while smoking or in the presence of sparks
or open flame. Allow the engine to cool briefly if you need to refuel
during operation.
- Always wear proper
protective equipment. Safety glasses or shield, safety helmet, hearing
protection, safety shoes, breathing protection, sturdy long pants, and
long-sleeved shirt are essential.
- Check all bits
to see that they are sharp. If not, sharpen according to the manufacturer's
recommendations. Always use eye protection when operating a grinder.
- Always disconnect
the electric power or air supply before inserting or removing tools.
- Be sure all tools
are properly locked into the unit before operating.
- Keep all bystanders,
children, and pets out of the work area.
- Prevent back injuries
by using your leg muscles to lift the machine into operating position.
- Allow the tool
to do the work by using a grip light enough to maintain control.
- Take rest breaks
as needed.
- If stopping work
for a short period of time or for the day, unplug the electricity or
stop the compressor.
