MAINTENANCE AND INSPECTION
CAUTION
Be sure to turned off the switch and remove the
battery before maintenance and inspection.
1. Inspecting the blade
Continued use of a dull or damaged blade will
result in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with
a new one as soon as excessive abrasion is noted.
2. Inspecting the mounting screws
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.
3. Maintenance of the motor
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.
4. Inspecting the carbon brushes (Fig. 31)
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.
NOTE
When replacing the carbon brush with a new one,
be sure to use the Hitachi Carbon Brush Code No.
999058.
5. Replacing carbon brushes
Take out the carbon brush by first removing the
brush cap and then hooking the protrusion of the
carbon brush with a flat head screw driver, etc., as
shown in
Fig. 33
.
When installing the carbon brush, choose the
direction so that the nail of the carbon brush agrees
with the contact portion outside the brush tube.
Then push it in with a finger as illustrated in
Fig. 34
. Lastly, install the brush cap.
CAUTION
Be absolutely sure to insert the nail of the carbon
brush into the contact portion outside the brush
tube (You can insert whichever one of the two nails
provided).
Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
6. Cleaning of the outside
When the Cordless Reciprocating 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, as they melt plastics.
7. Storage
Store the Cordless Reciprocating Saw in a place in
which the temperature is less than 40°C, and out
of reach of children.
8. Service parts list
