1. Ensuring the switch is off
○ If you insert the storage battery without knowing whether
the switch is engaged, the unit may unexpectedly start,
which may result in an accident.
○ When the switch is engaged while pressing the lock-
off button, the unit switches on, and when the switch is
released, the unit switches off .
2. Checking the saw chain tension
○ If the saw chain tension is incorrect, there is a risk of
damage to the saw chain or guide bar and malfunction.
Referring to steps 5 to 7 'Installing (replacing) saw
chain,' ensure an appropriate tension is set.
○ While the saw chain is still new, it is particularly
stretchy, so periodically check the tension and adjust
as required.
○ Also check the knob is securely tightened.
3. Checking operation of chain brake (Fig. 16)
WARNING
○ Although the chain brake is an emergency stop device,
this is not completely reliable. Operate carefully to
avoid the risk of kickback.
○ The chain brake is intended for use in emergencies and
when starting up. Do not use it indiscriminately.
○ To avoid impaired movement of the chain brake due to
buildup of sawdust etc., clean regularly.
○ The chain brake is an important component to ensure
safe use.
If you have any concern regarding the brake operation,
request repair from your Hitachi Authorized Service
Center.
The chain brake is an emergency stop device that stops
the saw chain when the unit is subject to kickback etc., to
reduce risk.
(Refer to 'Causes and operator prevention of kickback.')
When activating the chain brake by pushing the brake lever
forward, the saw chain stops moving.
If you pull the brake lever toward you, the brake is released.
When confi rming the operation of the chain brake, always
switch the unit off , remove the battery, activate the brake
lever and pull the saw chain by hand.
If the saw chain does not move, this means the chain brake
is activated.
NOTE
Always wear thick gloves for this task.
Since the saw chain blade is very sharp, pulling it hard
risks injuring your fi ngers.
4. Checking the chain oil
○ This unit is delivered without chain oil inside. Ensure the
oil tank is fi lled with the chain oil provided before use.
(Fig. 17)
○ Periodically check the oil sight glass during work and
replenish oil as required.
○ When you press the light switch on the switch panel,
an LED light turns on and the internal light improves
visibility. (Fig. 18)
(Check this in step 6.)
○ If the chain oil supplied runs out, use Hitachi chain oil
sold separately or equivalent chain oil on the market.
○ The chain oil lubricates automatically.
The discharge rate for auto lubrication is factory preset
to the maximum.
To reduce the discharge rate, turn the oil pump adjuster
on the rear of the body clockwise. (Fig. 19)
NOTE
○ The oil tank capacity is about 80 ml.
Even if overfi lled, excess oil will escape from the
overfl ow spout.
○ We recommend that you stock up with chain oil.
If you continue working without chain oil, the saw chain
may burn through, or the motor may fail.
18
○ Be careful to avoid dust or other foreign matter from
entering the oil tank.
If dust and other foreign matter enter the oil tank, the
unit may fail.
○ Chain oil left in the tank may leak due to the structure of
this unit. Although this does not indicate a malfunction,
it may soil the storage location, so be careful.
When storing, empty the oil from the oil tank, and place
an item under the main body which can absorb any
leaks.
5. Installing the storage battery (Fig. 3)
As shown in Fig. 3, push fi rmly until it clicks into place.
CAUTION
Securely attach the storage battery.
If the storage battery is not securely attached, it may
come off and injury may occur.
6. Checking if the LED light works (Fig. 18)
○ When you press the light switch, the LED light turns on
and when released, the light goes out.
○ The LED light illuminates the cutting edge section.
○ It lights up the inside of the oil sight glass to facilitate
checks of the remaining oil level.
NOTE
If the light is dirty, carefully wipe with a soft cloth etc., to
avoid damaging it.
If the light is damaged, this will reduce the brightness.
7. Checking brake is engaged
○ When the switch is engaged while pressing the lock-
off button, the unit switches on, and when the switch is
released, the unit switches off .
○ In addition, 1 to 3 seconds after releasing the switch,
the unit applies a brake to stop the rotation of the saw
chain.
○ Before using, check to ensure brake is engaged.
CAUTION
Be careful of the repulsive force when the brake is
engaged.
If you drop the unit, injury may occur.
8. Checking chain oil discharge (Figs. 19, 20)
○ When switching the unit on, chain oil automatically
lubricates the saw chain and guide bar.
○ If oil does not seem to emerge 2 to 3 minutes after
the unit starts, check if any sawdust has accumulated
around the oil spout.
(Refer to 'Cleaning the chain oil spout.')
(Refer to 'Checking the chain oil.')
Switch operation
When the switch is engaged while pressing the lock-off
button, the saw chain rotates. (Fig. 21)
Unless the lock-off button is pressed, the switch cannot
be engaged.
After the switch is engaged, the saw chain continues
rotating as long as it is pressed down. In addition, the
LED light remains lit up.
When the switch is released, a brake is applied to stop
the saw chain rotation.
WARNING
Do not secure the lock-off button while it is pressed.
If the switch is accidentally engaged, the unit may
unexpectedly start and injury may occur.
Using the hook
Pull out the hook from the unit, to which a rope etc. can
be tied to suspend the unit. (Fig. 23)
WARNING
When using the hook, ensure the unit is securely
suspended to avoid the risk of falling.
If the unit falls, an accident may occur.
