Rods have a tendency to roll while being cut, caus-
ing the blade to “bite” and pull the work with your
hand into the blade (Figure 47).

The brushes and commutator in your tool have been
engineered for many hours of dependable service.
To maintain peak efficiency of the motor, we recom-
mend every two to six months the brushes be ex-
amined. Only genuine Bosch replacement brushes
specially designed for your tool should be used.

To Inspect or Replace Brushes:
1. Unplug the saw.

/FA52/?B@5.@@2:/9F
2. Remove the brush cap on the motor using a wide
flat blade screwdriver.
3. Pull out the brush (Figure 48). Repeat for the op-
posite side.
NOTE: If installing the existing brush or brushes,
make sure the brush goes in the same way it came
out. Otherwise a break-in period will occur that will
reduce motor performance and increase brush wear.
4. Inspect brushes for wear. On the wide flat side of
brush is a wear limit line. If the brush contact
face is at or beyond (no line visible) the limit
replace brushes as a set.
5. Install new brush. The two (2) tabs on the brush
terminal go in the same hole the carbon part fits
into.
6. Tighten the brush cap but do not overtighten.
