10. Exhaust Gas Precautions
DANGER
Do not run the engine in a room or in any confined area where
exhaust emissions can accumulate. Doing so can result in an
accumulation of carbon monoxide and other poisonous gases that
can cause death or severe poisoning.
11. Saw Chain Precautions
DANGER
•
Do not allow your hand or foot to approach a pruning saw
chain in operation.
•
If you must touch the pruning saw chain in order to remove an
entangled branch or the like, turn off the mainunit and wait for
the pruning saw chain to fully stop.
•
Even after the pruning saw chain has stopped, wear heavy-
duty gloves and handle the chain with care. The cutting edges
of the pruning saw chain are very sharp and can cause death
or severe injury.
12. The Hazard Area
WARNING
•
Keep the working end of the machine at least 15 m away from
overhead power lines, telephone wires, and all other cables.
The machine is not insulated against external electric shock.
Electric shock can lead to death or severe injury.
•
Do not operate the device within 15 meters of a child, animal,
or bystander. Consider a 15-meter radius around the device to
be a “hazard area.”
•
If someone approaches the hazard area, immediately shut off
the engine.
Operation of the machine can result in falling or flying objects that
can lead to death or severe injury.
13. Limit your worktime
WARNING
•
Do not operate the machine for more than 2 hours a day.
•
Rest for 10 to 20 minutes after every 30 to 40 minutes of
operation.
Continuing to operate the machine without a break can result in
excessive fatigue. The resulting loss of attentiveness can lead to an
accident or problems with your fingers or hands. If you experience
any abnormal symptoms such as pain, discomfort, or paralysis of
the fingers or hand, immediately stop operating the machine and
seek medical attention.
14. Avoiding Electric Shock
WARNING
Never touch the spark plug cap or high-voltage wire while the
device is running. Doing so can result in a highvoltage electric shock
that can cause death or severe injury.
15. Avoiding Burns
CAUTION
Never touch the muffler, muffler cover, exhaust pipe, cylinder or
cylinder head while the machine is running or immediately after
operation, as they become very hot. Doing so can cause burns.
16. Using the Guide bar cover
CAUTION
•
Keep the guide bar cover on the pruning saw chain when the
pruning saw is not in use.
•
Before transporting the pruning saw, shut off the engine and
fit the guide bar cover on the pruning saw chain. Exercise care
when transporting it. The pruning saw chain is a very sharp tool
and can cause injury.
•
If transporting the machine in a vehicle, secure it to prevent
it from moving around. If the device can move freely during
transport, the fuel can spill or the device can be damaged.
Ensuring Safe Operation
CAUTION
To ensure safety, strictly observe the following instructions. Failure to
do so can lead to personal injury or severe damage to the machine.
1. Pre-operation inspection
Carefully inspect and perform any necessary maintenance before
starting the machine. Failure to do so can lead to severe property
damage or damage to the machine.
a.
Tighten or replace loose or lost screws.
b.
Replace any damaged or worn parts.
c.
Check for spilled fuel. Check the fuel tank cap and
wipe off any spilled fuel.
d.
Check that the saw chain is correctly tensioned.
e.
Check the level of chain oil in the oil tank.
For more information, see Inspection and maintenance.
2. Removing obstacles from the work area
Before starting operation, remove obstacles from the work area. Be
extremely careful about obstacles that can trip the operator, such as
tree roots, stumps, and holes.
3. Marking the hazard area
A circular area within a radius of 15 meters of the machine is the
hazard area. When necessary, mark the post a warning sign.
4. Wearing the Harness
•
Put on the harness before starting to work with the machine.
•
Adjust the length of the harness belt so that you can hold the
machine comfortably.
5. Starting the engine
•
In some cases, the saw chain can begin to run suddenly when
the engine is started. Maintain a safe area around you before
starting the engine.
•
Make sure that no bystanders are within 15 meters before
starting the engine.
•
Place the machine on flat solid ground before starting the
engine.
•
Make sure that no portion of the saw chain is in contact with
the ground or other object.
6. Checking the chain oil feed rate
Before starting the work, check that the chain oil is fed at the
correct rate. To do so, start the engine and allow the saw chain to
run. Point the end of the guide bar at a wood board or other flat
surface without allowing the saw chain to touch the board. Run the
chainsaw at a fairly high speed for 2 to 3 seconds. If a small amount
of chain oil has splashed onto the board, the chain oil feed rate is
appropriate.
For the procedure on adjusting the chain oil feed rate, see 13.
Adjusting the chain oil feed rate under Inspection and Maintenance.
7. Preparing for work
Gain experience at first by cutting small twigs and branches.
8. Safety Precautions
•
Hold the machine securely with both hands. Grip the control
handle with your right hand; hold the grip with your left hand.
•
To maintain a stable posture, adopt a stance wider than
shoulder width.
•
Maintain a firm footing.
•
Shut off the engine if abnormal noise or vibration occurs, if an
emergency occurs, or when putting down the machine.
•
If someone calls out or otherwise interrupts you while working,
always shut off the engine before turning around.
•
Plan a clear escape route should you need to avoid falling
items.
•
Before starting work, remove tree branches, leaves and other
obstacles that can limit your field of vision.
•
Determine the falling path of cut branches based on the angle
of the trunk, surrounding branches and twigs, the location
of neighboring trees, the presence of obstacles, and the
topography and wind direction.
•
To avoid injury from falling branches, remain aware of the path
of falling branches while working. Do not stand right below the
branches you are cutting.
