Spark Arrestor - DeWalt 55RI6HN Instruction Manual

SAFE OPERATION PRACTICES, cont'd
Children
1. Tragic accidents can occur if the operator is not alert to the presence of children.
Children are often attracted to the tractor and the mowing activity. They do not
understand the dangers. Never assume that children will remain where you last
saw them.
2. Keep children out of the mowing area and under watchful care of a responsible adult
other than the operator.
3. Be alert and turn mower off if a child enters the area.
4. Before and while moving backwards, look behind and down for small children.
5. Use extreme care when approaching blind corners, doorways, shrubs, trees, or other
objects that may obscure your vision of a child who may run into the mower.
6. Keep children away from hot or running engines. They can suffer burns from a
hot muffler.
7. Do not allow anyone to operate or maintain this machine who has not read the
manual. Never allow children under 16 years of age to operate this machine.
Hydraulic Devices & Systems
Hydraulic fluid escaping under pressure may have sufficient force to penetrate skin and to
cause serious injury. If foreign fluid is injected into the skin, it must be surgically removed
within a few hours by a doctor familiar with this form of injury, or gangrene may result.
WARNING: Keep body and hands away from pinholes or nozzles that could
eject hydraulic fluid under high pressure. Use paper or cardboard, not hands,
to search for leaks!
Safely relieve all pressure in the system before performing any work on the system, and
make sure that:
• The ignition switch is OFF
• The key is removed
• The engine spark plug wire(s) are removed
• All connections to the negative terminal of the battery are removed
• The park brake is set
• All by-pass valves, if so equipped, are open
• Hydraulic controls are actuated to release pressure on pumps, cylinders, etc. If "float"
positions are available, they should be used
After the above operations are completed, it should be safe to begin disconnecting the
lines or components. It is still a good idea to cover the connection with a cloth shield and
then gently loosen connections.
WARNING: Make sure all hydraulic fluid connections are tight and all
hydraulic hoses and lines are in good condition before applying pressure to
the system.
Service
safe handling of gasoline:
1. To avoid personal injury or property damage use extreme care in handling gasoline.
Gasoline is extremely flammable and the vapors are explosive. Serious personal injury
can occur when gasoline is spilled on yourself or your clothes, which can ignite. Wash
your skin and change clothes immediately.
2. Use only an approved gasoline container and fill slowly to decrease the chance of
static electricity buildup and spillage.
3. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner.
Always place containers on the ground away from your vehicle before filling.
4. Remove gas-powered equipment from the truck or trailer and refuel it on the
ground. If this is not possible, then refuel such equipment on a trailer with a portable
container, rather than from a gasoline dispenser nozzle.
5. Keep the nozzle in contact with the rim of the fuel tank or container opening at all
times until fueling is complete. Do not use a nozzle lock-open device.
6. Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
7. Never fuel machine indoors because flammable vapors will accumulate in the area.
8. If the fuel container spout will not fit inside the fuel tank opening, use a funnel.
9. If the fuel tank has to be drained, do this outdoors.
10. Never remove gas cap or add fuel while engine is hot or running. Allow engine to cool
at least 5 minutes before refueling.
11. Never over fill fuel tank. Fill the tank to the bottom of the filler neck, allowing some
space in the tank for fuel expansion.
12. Replace gasoline cap and tighten securely.
13. If gasoline is spilled, wipe it off the engine and equipment. Move machine to another
area. Wait 5 minutes before starting engine.
14. Never store the machine or fuel container near an open flame, spark, or pilot light as
on a water heater, space heater, furnace, clothes dryer, or other gas appliances.
15. To reduce fire hazard, keep machine free of grass, leaves, or other debris build-up.
Clean up oil or fuel spillage and remove any fuel soaked debris.
16. Allow machine to cool at least 5 minutes before storing.
general service:
WARNING: Never let children or untrained people operate or service
this mower.
1. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains
carbon monoxide, an odorless and deadly gas.
2. Before cleaning, repairing, or inspecting, make certain the blade and all moving parts
have stopped. Disconnect the spark plug wire and ground against the engine to
prevent unintended starting.
3. Check the blade and engine mounting bolts at frequent intervals for proper tightness.
Also, visually inspect blade for damage (e.g., bent, cracked, worn). Replace blade
with the original equipment manufacturer's (O.E.M.) blade only, listed in this manual.
Use of parts which do not meet the original equipment specifications may lead to
improper performance and compromise safety!
4. Mower blades are sharp and can cut. Wrap the blade or wear gloves, and use extra
caution when servicing them.
5. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe
working condition.
6. Never tamper with safety devices. Check their proper operation regularly.
7. If you hit a solid object while mowing, disengage the blade clutch, place the neutral
latch levers in the neutral lock position, shift the transmission into neutral, and stop
the engine. Disconnect the spark plug wire(s) and inspect for damage. Repair any
damage and make sure the blades are in good condition and the blade bolts are tight
before restarting the engine.
8. Never attempt to make a wheel or cutting height adjustment while the engine
is running.
9. Grass catcher components, discharge cover, and trail shield are subject to wear and
damage which could expose moving parts or allow objects to be thrown. For safety
protection, frequently check components and replace immediately with original
equipment manufacturer's (O.E.M.) parts only, listed in this manual. Use of parts
which do not meet the original equipment specifications may lead to improper
performance and compromise safety!
10. Do not change the engine's governor setting or over-speed the engine. The governor
controls the maximum safe operating speed of the engine.
11. Check fuel line, tank, cap, and fittings frequently for cracks or leaks. Replace
if necessary.
12. Do not crank engine with spark plug removed.
13. Maintain or replace safety and instruction labels, as necessary.
14. Follow this manual for safe loading, unloading, transporting, and storage of
this machine.
15. Always refer to the Operator's Manual for proper instructions on off-season storage.
16. Observe proper disposal laws and regulations. Improper disposal of fluids and
materials can harm the environment.
Do Not Modify Engine
To avoid serious injury or death, do not modify engine in any way. Tampering with the
governor setting can lead to a runaway engine and cause it to operate at unsafe speeds.
Never tamper with factory setting of engine governor.
Notice Regarding Emissions
Engines which are certified to comply with California and federal EPA emission
regulations for SORE (Small Off Road Equipment) are certified to operate on regular
unleaded gasoline, and may include the following emission control systems: Engine
Modification (EM), Oxidizing Catalyst (OC), Secondary Air Injection (SAI) and Three Way
Catalyst (TWC), if so equipped.
When required, models are equipped with low permeation fuel lines and fuel tanks for
evaporative emission control. California models may also include a carbon canister. Please
contact Customer Support for information regarding the evaporative emission control
configuration for your model.

Spark Arrestor

WARNING: This machine is equipped with an internal combustion engine
and should not be used on or near any unimproved forest-covered, brush-
covered, or grass-covered land unless the engine's exhaust system is
equipped with a spark arrestor meeting applicable local or state laws (if any).
