TRIGGER SWITCH (Model 4480 & 4540 only)

Your tool is equipped with a variable speed trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The speed can be adjusted from the minimum to maximum nameplate SPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).

ELECTRONIC FEEDBACK CIRCUITRY (EFC)

(Model 4580 only)

The internal electronic feedback system helps to keep the no load speed virtually constant between no-load and load conditions.

PLUNGER SPEED

The stroke rate may be adjusted as described earlier under “Variable Speed Dial”. The best results for a particular application is determined by experience, though as a general rule, slower speeds are for denser materials and faster speeds are for soft materials.
