Northern Industrial Tools 143379 - Manual (Page 4)

23. Avoid accidental starting. Be sure your tool is turned off before plugging it in. Do not use
a tool if the power switch does not turn the tool on and off. Do not carry a plugged-in tool
with your finger on the switch.
24. Do not force tool. Your tool will perform better at the rate for which it was designed.
Excessive force only causes operator fatigue, increased wear and reduced control.
25. Do not abuse cord. Never carry your tool by its cord or unplug it by pulling the cord from
the outlet. Pull the plug rather than the cord to reduce the risk of damage. Keep the cord
away from heat, oil, sharp objects, cutting edges and moving parts.
26. Maintain tools carefully. Keep handles dry, clean and free from oil and grease. Follow
instructions for lubricating and changing accessories. Periodically inspect tool cords and
extension cords for damage. Refer all service to a qualified technician.
27. Store idle tools. When not in use, store your tool in a dry, secure place. Keep out of
reach of children.
28. Never operate grinder without using a guard.
