Power Management System
For models that include a power management system, the system allows operator reduction of maximum
output power in either the forward or the reverse direction.
For reduced power in the forward direction and full power in the reverse direction
, push the reverse
valve inward on the right side of the tool and rotate the reverse valve until the notch on the right side aligns
with the desired number on the right side. This provides reduced power in forward but full power in reverse
when the reverse valve is pushed in the opposite direction. (See TPD1248 on page 2.)
For reduced power
in the reverse direction and full power in the forward direction
, push the reverse valve inward on the left
side of the tool and rotate the reverse valve until the notch on the left side aligns with the desired number on
the left side. This provides full power in forward but reduced power in reverse when the reverse valve is
pushed the opposite direction. (See TPD1249 on page 2.)
For full power in both directions
, rotate the
Reverse Valve until the notch on each end of the Reverse Valve aligns with 5 on each side of the housing.
The power level indicators (See TPD1248 and TPD 1249) are for reference and DO NOT indicate a specific
power. The power output can be further reduced in forward or reverse by using the variable throttle.
