ABOUT THIS MANUAL
The following symbols are used in this guide:
This symbol indicates a CAUTION. Cautions warn against actions that can cause
damage to equipment. Please read these carefully.
This symbol indicates a WARNING. Warnings alert you to actions that can cause
personal injury or pose a physical threat. Please read these carefully.
NOTES and TIPS contain helpful information.
INTRODUCTION
Your micromanipulator is a precision instrument. It has been calibrated at the factory and
is ready for use. As with any delicate mechanical device, it needs your care and attention
for long term accurate performance. The following are some helpful hints to make this
possible.
Notes and Warnings
CAUTION: When handling a micromanipulator, set it down gently. Dropping it
(even a short distance) can be damaging to the general alignment and
adjustment.
CAUTION: When not in use, adjust the three (X-Y-Z) guide surfaces in such a way
that they are not exposed and cover the manipulator with a plastic bag. Dirt is
your biggest enemy.
CAUTION: If the manipulator is not in use for a prolonged time, occasionally
work the three surfaces repeatedly back and forth to keep the grease pliable.
Never oil the guide surfaces and under normal use you should not have to apply
grease for many years.
CAUTION: When using the motorized version always be sure to check that the
edge of the micrometer is aligned with the red dots on the motor housing in each
axis before using the manual control for coarse positioning. Running the
motorized axes repeatedly against either end limit can damage the motor. Be advised
that this damage is not covered by any warranty.
CAUTION: When using the dual tool holder micromanipulators, Models MD4R
and MD4L, be careful not to twist the revolving, spring-loaded axes too hard or
too far. This may damage the spring.

INSTALLING THE TILT BASE
Fig. 1—(Left) M3 Tilting Base.
Fig. 2—(Right) The M3301 is installed on an M3 Tilting Base with an optional 5 lb. weight
(WPI# 5464).
To install the M3 Tilting Base, remove the ring clamp by removing the two screws with
the Allen wrench provided. Attach the manipulator to the tilting base by using the two
screws provided with the M3. Only two screws are required, because two holes are used
with a right-handed manipulator, and the other two holes in the tilting base are used for
the left-handed version.
ADJUSTING THE ANTI-DRIFT TENSION ON
MICROMANIPULATORS
Fig. 2 shows a side view of the M3301L manual micromanipulator. Depending on the
angle of application and the weight carried on any one guide-way, you may experience
some drift. This can be easily corrected. Follow the procedure on the following pages to
tighten the drag on the coarse manual slides.
In this manual, you can see how to adjust the anti-drift tension on the M3301, but the
procedure is similar for the DC3001R, DC3001L, MD4R, MD4L, KITE-L, KITE-R,
MMJR and MMJL. A micromanipulator axis may begin to move gradually under its
own weight even if it’s not being touched. This phenomenon is referred to as mechanical
drift. It occurs from normal use of the of the manipulator axes over time. Each coarse
axis control (shown below) of the micromanipulator has its own separate adjustment to
counteract drift. What follows is the basic procedure to eliminate drift in each of the axes
through adjustment of the anti-drift tension.

Adjusting the X Coarse Axis Drift
1. The first step is to rotate the X-Axis Coarse Adjustment knob clockwise until the
x-axis reaches the end of its travel in the fully extended position as indicated by the
black arrow in Fig. 4. This is necessary, because it provides better access to the knob.
In step 2, you will use a pair of pliers to secure this knob while loosening the black
locking nut so that the adjustment can be made.
Fig. 4—Fully extend the X-axis away from adjustment knob.
2. Use a pair of pliers to secure the X-Axis Coarse Adjustment knob to prevent it from
rotating (Figure 3). Don’t grab the knob with the pliers directly, because the jaws will
cut into the aluminum knob. Instead, take a piece of paper and fold it about ½“ wide

4 World Precision Instruments
over upon itself 5 or 6 times to make it thicker. Then, wrap it around the knob to
protect the knob.

several times
Fig. 5—Wrap the knob with a thick layer of papers so the pliers do not gouge the
aluminum knob.
3. If you are right-handed, hold the pliers in your left hand. With your right hand
insert the special tool (WPI# 502105) (Fig. 6) into the black slot on the end of the
knob. Prevent the silver knob from turning, and rotate the tool counter-clockwise to
unscrew the black locking nut (Fig. 7).
Hold knob and turn
screw counter-
clockwise.
Fig. 6—(Left) 502105 Manipulator Adjustment Tool
Fig. 7—(Right) The outer ring of the knob remains stationary, while you turn the inner
screw counter-clockwise.
4. Once the black locking nut is loose, the silver knob can be freely tightened or
loosened to adjust the amount of resistance to drift. To prevent the axis from moving
while making the tension adjustment, use your left hand to hold the body of the

Micromanipulator Care Guide
World Precision Instruments 5
axis securely while adjusting the silver knob (clockwise to increase tension) with
your right hand. At some point you will feel the resistance of the knob increase
as it begins to compress against the spring steel and nylon friction components.
Adjustment is somewhat arbitrary. When the amount of tension feels about right, use
the 502105 tool to re-tighten the black locking nut to secure the adjustment. Then,
test the anti-drift tension.
5. Test the drift resistance of the axis by pushing on it with your hand to see how easily
it moves. A good technique for doing this is to push on the axis body with your left
thumb while providing a counteracting force on the lower part of manipulator using
your right hand (Fig. 8). When the tension is adjusted correctly, it will not be easy to
move the axis by pushing it.
Apply mechanical
pressure on the X-
axis with left hand
thumb to test for
drift resistance.
Fig. 8—To test the drift resistance, press on the x-axis. It should not move easily.
NOTE: The correct amount of drift resistance depends upon the working orientation of
the manipulator, the load on the axis, and personal preference.
6. If the action feels too tight or too loose, unscrew the black locking nut again and re-
adjust the tension accordingly. It may be necessary to repeat this procedure several
times. Typically, the goal is to get the tension just tight enough to prevent the axis
from drifting under its own weight (while loaded), but not any tighter than necessary
to achieve this end. The correct amount of tension often occurs within a narrow
range of adjustment. If you make it too tight, the knob will be harder than necessary
to turn and the friction components will wear faster. This procedure requires
patience!

Adjusting the Y-Axis Drift
The adjustment of the Y-axis tension is performed with essentially the same techniques
as that described for the X coarse axis. The Y-axis is controlled by the Y-Axis Coarse
Adjustment knob shown in Fig. 3.
If the manipulator is operated in standard position (with the electrode clamp located
above the manipulator body as shown in Fig. 2, then the Y-axis does not typically have
a tendency to drift unless the manipulator body is tilted to the left or right relative to the
vertical plane passing parallel through the X-axis.
Adjusting the Z Axis Drift
The Z-axis is notorious for drifting, since it is subject to gravitational forces generated by
the weight of the entire manipulator body and the load.
The adjustment to counteract drift on the Z-axis is performed differently than either the X
or Y axes. The Z-axis is controlled by the Z-Axis Coarse Adjustment knob shown in Fig. 3.
However, the tension is adjusted by rotating the Adjustment Ring.
1. Locate the set screw on the Adjustment Ring (Figure 6).
Set Screw
Fig. 9—The set screw is located on the adjustment ring.
2. Using a small flat blade screwdriver, loosen the set screw by turning the screw
counterclockwise. This will free the Adjustment Ring to allow it to be rotated.
3. Adjust the tension on the Z-axis. The Adjustment Ring may be difficult to turn
manually, because access is limited by the larger diameter Z-axis and Y-axis
Adjustment knobs which surround it. Once the set screw has been loosened, It may
be easier to turn the Adjustment Ring if you keep the screwdriver blade inserted into
the screw and orient the flat blade perpendicular to the direction of the turn. (Fig.
10).

Micromanipulator Care Guide
World Precision Instruments 7
Fig. 10—The flat blade of the screwdriver should be positioned perpendicular to the
adjustment ring to make the ring easier to rotate.
4. The perpendicular position of the screwdriver creates a leverage point for using the
screwdriver to amplify the force applied to turn the ring.
CAUTION: Don’t unscrew the setscrew too much or it will fall out.
CAUTION: Be careful not to let the screwdriver blade slip out of the screw slot,
which could damage the slot or cause personal injury.
TIP: With older manipulators, the Adjustment Ring may be too tight to turn, even using
the screwdriver technique just described. If this is the case, remove the Y-axis
Adjustment knob to gain better mechanical access for the use of pliers.
To remove the Y-axis Coarse Adjustment knob, remove its black locking nut with the
502105 tool. Then, turn the knob counter-clockwise to remove it altogether. Note
the order and orientation of the nylon and spring washer friction components. When
the Z-axis tension adjustments are complete, re-install the friction components and
the Y-axis Coarse Adjustment knob in reverse order of disassembly. Then, re-adjust
the Y-axis tension.
