○ Periodically check the oil sight glass during work and
replenish oil as required.
○ If the chain oil supplied runs out, use HiKOKI 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 right side of the oil sight glass clockwise.
(Fig. 16)
NOTE
○ The oil tank capacity is about 70 ml.
Make sure no oil leaks or overfl ows from the oil tank
when replenishing the chain oil.
○ 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.
○ 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.
○ Replenish the oil after every approximately 10 minutes
of operation. (*Varies depending on the cutting usage
conditions)
4. Installing the battery (Fig. 5)
As shown in Fig. 5, push fi rmly until it clicks into place.
CAUTION
Securely attach the battery.
If the battery is not securely attached, it may come off
and injury may occur.
5. Checking operation of chain brake (Fig. 17)
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 chain brake
operation, request repair from your HiKOKI 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.")
Push the chain brake in the direction indicated by the arrow
(
) to apply the chain brake and stop the saw chain. To
release the chain brake, release the switch and pull back
on the chain brake.
CAUTION
The chain brake functions only when power is turned
on. Check chain brake function in a location with no
people or obstructions nearby.
(1) Press the switch while sliding the lock-off lever.
(2) Once the saw chain begins turning, push the chain
brake forward toward the saw chain.
(3) If the saw chain stops, the chain brake is functioning as
it should. To release the brake, release the switch and
pull back on the chain brake.
6. Checking chain oil discharge (Fig. 18)
○ 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.")
REMAINING BATTERY INDICATOR
You can check the battery's remaining capacity by
pressing the remaining battery indicator switch to light the
indicator lamp. (Fig. 20, Table 3)
The indicator will shut off approximately 3 seconds after
the remaining battery indicator switch is pressed.
It is best to use the remaining battery indicator as a
guide since there are slight diff erences such as ambient
temperature and the condition of the battery.
Also, the remaining battery indicator may vary from those
equipped to a tool or charger (Battery is not included, sold
separately).

CUTTING PROCEDURES
WARNING
○ When working in trees, wear appropriate protection on
your eyes, head, hands, legs, and arms, as well as slip-
resistant foot protection.
○ Prior to operation, ensure that chain brake works.
○ During use, grip the handle securely with both hands.
(Fig. 3)
○ When cutting timber from the bottom, ensure the saw
chain does not impact with the timber.
If the unit is pushed back, injury may occur.
○ During work breaks or after work, always switch the unit
off , and remove the battery from the main body.
