○ Adjustment of depth gages must be in line with the
predetermined dimensions and shapes, otherwise the
risk of kickback may increase, causing an injury.
Bumper tie strap
Depth gages shall be all lined up in the same manner
because they are used to adjust depth at the position
where the cutter inlays into the wood.
When sharpening the saw chain, be sure to check the
depth gage every two or three times.
Place a depth gage jointer on the saw chain, leave the
gage visible at the groove, and use a fl at fi le to bevel the
portion out of the depth gage jointer. (Fig. 38) (Depth
gage jointer and fl at fi le are sold separately.)
After fi ling away the depth gage, round off the front side
of the depth gage as it was. (Fig. 39)
After sharpening the saw chain, place it into chain oil to
wash off the fi lings.
If fi lings are not cleaned off , the saw chain and guide
bar will quickly wear while in use.

MAINTENANCE AND INSPECTION
After operation, perform inspection and maintenance of
each part when storing the unit.
WARNING
During maintenance and inspection, always switch off
the unit and remove the storage battery from the main
body. In addition, disconnect the power plug of the
charger from the outlet.
1. Inspection of saw chains
○ Occasionally inspect the saw chain. In the event of
any abnormality, replace it with a new one referring to
"Installing (replacing) saw chain" .
○ Inspect the chain tension and check If it is correctly
tightened.
○ Stop using the unit when the saw chain becomes blunt
and sharpen it referring to "Sharpening of the chain
blade".
○ After use, carefully lubricate the saw chain and guide
bars with oil for rust-proofi ng.
CAUTION
Wear gloves to avoid injury while using a saw chain.
2. Cleaning the side cover and brake band chamber
(Figs. 40, 41)
Clean and remove any sawdust left inside the parts.
NOTE
When cleaning the side cover, brake band chamber,
chain oil spout, and side bar, see the procedure
"Installing (replacing) saw chain" and remove the saw
chain.
3. Cleaning the chain oil spout (Fig. 42)
Before cleaning the chain oil spout, remove the side
cover and guide bar.
4. Cleaning the guide bar (Figs. 9, 43)

5. Inspecting the carbon brushes (Fig. 44)
NOTE
6. Replacing carbon brushes
CAUTION
○ Be absolutely sure to insert the nail of the carbon brush
○ Caution must be exercised since any error in this
7. Inspecting the mounting screws
8. Maintenance of the motor
9. Inspection of terminals (tool and battery)

11. Storage
NOTE

When sawdust and similar become clogged in the
groove of the guide bar or oil spout, the oil may not fl ow,
which may result in the unit failing.
Remove the guide bar and clean any sawdust clogged
in the groove after use and when replacing the saw
chain. (Refer to "Installing (replacing) saw chain.")
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
When replacing the carbon brush with a new one,
be sure to use the HiKOKI Carbon Brush Code No.
999068.
Take out the carbon brush by fi rst removing the brush
cap and then hooking the protrusion of the carbon
brush with a slotted head screw driver, etc., as shown
in Fig. 45.
When installing the carbon brush, choose the direction
so that the nail of the carbon brush (see Fig. 46) agrees
with the contact portion of brush tube. Then push it in
with a fi nger as illustrated in Fig. 47. Lastly, install the
brush cap.
into the contact portion of brush tube. (You can insert
whichever one of the two nails provided.)
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
The motor unit winding is the very "heart" of the power
tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
When the chain saw is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
When storing the unit, perform cleaning and
maintenance of each part and mount the chain case to
the guide bar.
Store the chain saw in a place where the temperature is
less than 40°C and out of reach of children.
Storing Lithium-ion Batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
