SAFETY PRECAUTIONS
Battery and Electrical Safety
• Ignitable explosive gases are
emitted from the battery. DO NOT
expose the battery to sparks or open
flames.
• Keep the area around the battery well-
ventilated.
• Keep the battery level when handling it.
• Use protective eyewear or a face shield, and
avoid contact with the skin when
handling/servicing the battery.
• Use a proper battery tester when testing the
battery strength.
• Always be sure to connect the battery cables to
the proper terminal when reconnecting the
cables.
• Occasionally inspect the battery, cables,
clamps, and terminals for damages. Service
components as necessary.
• Always keep the battery cable clamps away
from the battery terminals when the battery is
disconnected to avoid accidental connections
while servicing.
• Immediately rinse your clothing, skin, or eyes
with water if exposed to battery acid. Seek
medical attention immediately!
• Disconnect the battery prior to servicing all
equipment components (unless stated
otherwise).
• Remove the battery when storing the
equipment for longer periods.
• Always use the correct size fuses (amps) to
prevent fires.
Blade Safety
• Always use reinforced abrasive blades or steel-
centered diamond blades.
• Never use a wet cutting blade without an
adequate water supply to properly lubricate the
blade.
• Inspect all blades prior to usage and discard
damaged blades.
• DO NOT install or remove a blade with the
engine running.
• Keep all body parts away from rotating blades.
• Inspect the blade flanges for damages, wear,
and cleanliness. Clean or replace
dirty/damaged components immediately.
• DO NOT expose yourself or anyone
else to the direct line of the blade
when operating the equipment.
• Always use an appropriate size blade and the
correct blade type based on the cutting task
and the type of material being cut.
• The blade must always fit snug on the blade
shaft, outer flange, and/or inner flange.
• Wear gloves and be alert to the surrounding
environment when handling blades.
• When installing the blade, always point the
arrow printed on the blade in the direction of the
blade shaft’s rotation.
• DO NOT exceed the blade’s maximum
recommended speed when cutting. Excessive
blade speeds can cause blade breakage,
resulting in serious injuries and/or death!
• DO NOT use damaged blades when cutting to
avoid harming yourself, others, or the
equipment.
• DO NOT use a blade for cutting that requires a
lower speed than the blade shaft speed.
• Always tighten the blade shaft bolt/screw as
directed to properly secure the outer flange and
blade. Failure to properly secure the outer
flange and blade may cause parts to loosen or
fall off the equipment, resulting in serious
injuries or death!
• Let the blade cool prior to removal when dry
cutting (applicable models).
Blade Guard Safety
• DO NOT operate the equipment with the blade
guard raised or removed.
• Blade exposure should not exceed 180° while
cutting.
• When pivoting the front of the blade guard,
raise/lower it cautiously and slowly to avoid
serious injuries.
• DO NOT pivot the blade guard front up or down
when installing/removing very large blades.
Attempting to pivot the front of a heavy guard
when the guard is positioned higher up for
blade installation/removal makes the guard
difficult to lift and/or lower. In this situation,
install/remove the blade guard front instead of
pivoting it.
