Saw Operations

Cutting Round or Irregularly

Shaped Material

for round material such as ! WARNING dowel rods or tubing, always

use a clamp or a fixture designed to clamp the workpiece firmly against the fence and table.

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).

Service

We recommend that all tool service be performed by a Bosch factory Service Center or Authorized

Bosch Service Station. preventive maintenance performed by unauthorized personnel may re- sult in misplacing of internal wires and compo- nents which could cause serious hazard.

Motor Brushes

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.

Motor Brush Replacement

To Inspect or Replace Brushes:

1. Unplug the saw.

! WARNING

The brush cap is spring loaded

 

by the brush assembly.

 

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.

Cleaning

To avoid accidents, always dis- connect the tool from the power supply before cleaning or performing any main-

tenance. The tool may be cleaned most effec- tively with compressed air. Always wear safety goggles when cleaning tools with compressed air.
