CC4144D Concrete Saw Manual 3
Blade Safety
• Always use reinforced abrasive blades or steel-
centered diamond blades.
• Inspect all blades prior to usage and discard
damaged blades. Remove debris from blades and
clean as necessary.
• 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, repair, or replace damaged
components immediately.
• DO NOT expose yourself or anyone
else to the direct line of the blade when
operating the saw.
• Always use an appropriate size blade for the cutting
task.
• Wear gloves and be alert to the surrounding
environment when handling blades.
• Always point the arrow printed on the blade in the
direction of the blade shaft’s rotation when installing
the blade.
• Always use the correct blade type for the material
being cut.
• 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 saw.
• DO NOT use a blade for cutting that requires a lower
speed than the blade shaft speed.
• Tighten the blade shaft screw as directed to secure
the outer flange and blade. Failure to properly
secure the outer flange and blade may cause parts
to loosen or fall off the saw.
Blade Guard Safety
• DO NOT operate the saw with the blade guard
raised or removed.
• Blade exposure should not exceed 180° while
cutting.
• Always pivot the front of the blade
guard 180° (fully upward) so the guard
does not swing down unexpectedly,
which may cause serious injuries.
• When lowering the front part of the blade guard,
pivot it cautiously and slowly to avoid serious
injuries.
• DO NOT remove the blade guard with the engine
running.
• Always use a blade guard that corresponds with the
blade size.
• Inspect the blade guard and water tubes prior to
operating the saw. Clean, repair, or replace
damaged components immediately.
Fuel Safety
• Store all fuel in appropriate safety containers.
• DO NOT operate the saw with a fuel leak.
• DO NOT fuel the saw with the engine running.
• Let the engine cool prior to adding fuel.
• Refer to the engine manual for recommended diesel
fuels.
• Fuel may seep out from the fuel cap vent when the
saw is raised if the fuel tank is overfilled (applicable
models).
• DO NOT smoke or expose fuel to open
flames when filling the fuel tank or
working with fuel.
• Clean up spilled fuel prior to starting the engine.
• Move the saw away from the fueling area prior to
starting the engine.
• Always use appropriate diesel fuels in cold weather.
• Drain the fuel tank and fuel lines for longer storage
periods. Refer to the engine manual for additional
information.
Engine Safety
• Refer to the engine manual as the primary source
for engine safety.
• Always know how to turn off the engine for
emergency purposes.
• Place the speed control lever at Neutral to prevent
saw movement when starting the engine.
• Fill the fuel tank and check the oil level prior to
starting the engine.
• Keep all body parts away from
rotating saw parts with the engine
running.
• DO NOT start the engine without the air filters
installed.
• DO NOT allow dust to enter the air intake tube when
cleaning/replacing air filters.
• Immediately replace damaged saw components that
may allow dust to enter the engine.
• DO NOT use any starter substances or starter fluids
when starting the engine using a glow plug (e.g.,
starter fluid sprayed into the air filter). These
materials are extremely flammable and explosive,
and can melt parts or possibly explode when used to
help start the engine.
