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
