(3) Hold the body firmly until the saw blade
completely cuts into the material. (Fig. 26,
Fig. 27)
MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during 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 loosened, retighten them immediately.
WARNING: Using this reciprocating saw with
loosen screws is extremely
dangerous.
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 noto become damaged and/or wet
with oil or water.

CAUTION:
Avoid plunge cutting for metallic materials.
This can easily damage the blade.
Never pull the switch trigger while the tip of
the saw blade tip is pressed against the
material. If you do so, the blade can easily be
damaged when it collides with the material.
Make absolutely sure that you cut slowly
while holding the body firmly. If you apply
any unreasonable force to the saw blade
during the cutting operation, the blade can
easily be damaged.
4.
Inspecting the carbon brushes (Fig. 28)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or
near the "wear limit", it could result in motor
trouble. When an auto-stop carbon brush is
equipped, the motor will stop automatically. At that
time, replace both carbon brushes with new ones
which have the same carbon brush Numbers
shown in the figure. In addition, always keep
carbon brushes clean and ensure that they slide
freely within the brush holders.
