Maintenance And Inspection - Hitachi CR13VBY - 12 Amp TOOLESS Low Vibration Reciprocating Saw Instruction Manual

MAINTENANCE AND INSPECTION

WARNING:
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:
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.
4. Inspecting the carbon brushes (Fig. 30)
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.

Be sure to switch power OFF and disconnect the plug from the

Using this reciprocating
saw with loosen screws
is extremely dangerous.

5. Replacing carbon brushes
Disassemble the brush caps with a
slotted-head screwdriver. The carbon
brushes can then be easily removed.
6. Service and repairs
All quality power tools will eventually
require servicing or replacement of parts
because of wear from normal use. To
assure that only authorized replacement
parts will be used, all service and repairs
must be performed by a HITACHI
AUTHORIZED SERVICE CENTER, ONLY.
