WARNING
To avoid an accident or personal injury, always
confirm that the trigger switch is turned OFF and
the power plug has been disconnected from the
receptacle before performing any maintenance
or inspection of this tool.
Report to qualified person as soon as possible, if
you discover the fault of machine including
guards or blade saw.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the
first sign of deterioration or damage.
A damaged saw blade can cause personal injury and
a worn saw blade can cause ineffective operation and
possible overload to the motor.
CAUTION
Never use a dull saw blade. When a saw blade is
dull, its resistance to the hand pressure applied
by the tool handle tends to increase, making it
unsafe to operate the power tool.
2. Inspecting the carbon brushes (Fig. 51 and Fig. 52)
The carbon brushes in the motor are expendable
parts.
If the carbon brushes become excessively worn,
motor trouble might occur.
Therefore, inspect the carbon brushes periodically
and replace them when they have become worn to
the wear limit line as shown in Fig. 51.
Also, keep the carbon brushes clean so that they will
slide smoothly within the brush holders.
The carbon brushes can easily be removed after
removal of the brush caps (see Fig. 52) with a slotted
(minus) screwdriver.

NOTE
When replacing the carbon brushes, use only
metabo HPT carbon brushes having "38" in the last
two digit of its Code No. (see Fig. 51). If you use other
carbon brushes, the electric brake will not operate.
3. About Handling the Motor (see Fig. 2)
Winding of the motor is said to be the heart of this
tool. Exercise utmost caution not to damage the
winding by exposing it to wash oil or water.
NOTE
Accumulation of dust and the like inside the motor
can result in a malfunction.
After using the motor for 50 hours or so, carry out no-
load running, and blow in the dry air from a wind hole
at the motor's rear. Such action is effective to
discharge dust and the like.
4. Inspecting the screws
Regularly inspect each component of the power tool
for looseness.
Re-tighten screws on any loose part.
WARNING
To prevent personal injury, never operate the
power tool if any components are loose.
5. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (see
Fig. 8) to assure that it is in good condition and that it
moves smoothly.
Never use the tool unless the lower guard operates
properly and it is in good mechanical condition.
NOTE
If the lower guard does not move smoothly, request
repairs from the dealer from which you purchased the
tool.
