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
(mm)
reduced cutting effi ciency 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
3.5
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
3.5
NOTE
100
When replacing the carbon brush with a new one,
100
be sure to use the HiKOKI Carbon Brush Code No.
999058.
100
5. Replacing carbon brushes
Take out the carbon brush by fi rst removing the brush
cap and then hooking the protrusion of the carbon
brush with a fl at 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 fi nger 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.
