| To remove
the clutch housing from the tool to expose the clutch: Grasp the motor
housing firmly with one hand and with the other hand, grasp the clutch
housing firmly. Turn the clutch housing clockwise and continue rotation
until the clutch housing falls away from the tool. |
 |
 |
| To install
the clutch housing back onto the tool: Grasp the motor housing firmly
with one hand and with the other hand, grasp the clutch housing. Thread
the clutch housing onto the tool by rotating the clutch housing counter
clockwise until the clutch housing is tight against the motor housing.
Be careful not to over-tighten. To prevent cross threading, start
threading the clutch housing gently onto the motor housing until it
gets started. |

Torque
Units and Conversion Factors
Torque is the application of a force at a radial distance tending
to cause rotation. The International Standards Organization (ISO)
recommends the following units for denoting torque: |
Torque
Units
|
Imperial
|
Metric
|
International System
|
|
ozf-in-ounce force inch
lbf-in-pound force inch
|
kgf-cm-kilogram force centimeter
|
N-m-Newton meter
|
|
|
Example 1:
Convert 10 lbf-in into kgf-cm 10 X 1. 152 = 11.52 kgf-cm
Example 2:
Convert 10 kgf-cm into ozf-in 10 X 13.89 = 138.9 ozf-in |

Adjust the
2000 Series Auto Shut-off Clutch:
Adjusting the 2000 series auto shut off clutch requires two crescent
wrenches. With the clutch facing as shown in drawing, attach wrench
#1 to the 1/4" threaded shaft and wrench #2 to the clutch adjustment
nut. Hold wrench #1 firm while rotating wrench #2 clockwise to increase
torque value and counter-clockwise to decrease torque value. Use a
torque tester to
determine exact torque value, such as our Model 4201 or 4202. |
 |
|
Adjust the
2000 Series Cushion Clutch:
To adjust the 2000 series cushion clutch requires a 1/16" hex key
and any screwdriver bit. Insert the hex key into the set screw and
remove by a counter clockwise motion. Next, holding the clutch as
shown in drawing, insert the screwdriver bit into the 1/4" hex female.
Turning the screwdriver bit clockwise will increase the torque value,
while a counter-clockwise motion will decrease the torque value. The
set screw hole needs to be in view of one of the two eyelet holes
when torque value is reached. Make sure to screw in clockwise the
set screw for each test for torque value or install the clutch back
into the tool. Use a torque
tester to determine exact torque value, such as our Model 4201
or 4202. |

Adjust the
8000 Series Auto Shut-off or Cushion Clutch:
Adjusting an 8000 series auto shut off clutch or cushion clutch requires
a #2 Phillips screwdriver. Adjust these clutches while in the tool
or out of the tool (as shown in drawing). To adjust the clutch in
the tool, rotate the black "C" ring to expose the clutch in the eyelet.
Next, rotate the clutch so that the clutch adjustment hole is exposed
in the eyelet. With the tool or the clutch facing in the direction
shown in the drawing, place the #2 Phillips screwdriver in the clutch
adjustment hole. Turn the screwdriver counter-clockwise to increase
the torque value, and clockwise to decrease the torque value. Use
a torque tester
to determine exact torque value, such as our Model 4201 or 4202. |
