Do not force equipment. 

 

Equipment will perform best at the rate for which it was designed. 
Excessive force only causes operator fatigue, increased wear, and 
reduced control.

Use proper parts and accessories.  
Only use NFE-approved or recommended parts and accessories. 
Using any that are not recommended may be hazardous. 
Ensure accessories are properly installed and maintained.
Do not permanently remove a guard or other safety device when 
installing an accessory or attachment. 
Inspect for damaged parts.  
Check for misalignment, binding of moving parts, loose fasteners, 
improper mounting, broken parts, and any other conditions that 
may affect operation. If abnormal noise or vibration occurs, turn 
the machine off immediately. Do not use damaged equipment until 
repaired. Do not use if power switch does not turn machine on and 
off. For all repairs, insist on only identical NFE replacement parts.
Maintain equipment and labels.  
Keep handles dry, clean, and free from oil and grease. Keep cut-
ting edges sharp and clean. Follow instructions for lubricating and 
changing accessories. Motor and switches should be completely 
enclosed at all times with no exposed wiring. Inspect cord regu-
larly. Labels carry important information; if unreadable or missing, 
contact NFE for a free replacement. 
Avoid accidental starting; store idle equipment.  
When not in use, ensure that the machine is unplugged; do not 
turn on before plugging in. Store in a dry, secured place. Remove 
tooling when storing, and keep away from children.
