Series: C
This setting details a unit with a HCU,
reference to the HCU should be ignored
when setting the standard tool.
● Set the gap between the (1) and (2) to equal
the depth of drilling required PLUS the
distance the bit is above the work piece, by
sliding (3).
● Lock in position with (4) to the recommended
torque.
● Position the HCU in (3).
● Set the gap between (6) and (7) to a distance
as required above the work piece.
● Unscrew (8) away from the HCU to adjust the
resistance within the HCU to the minimum.
● Fully open the Figure 3 (13).
● Close Figure 3 (11).
● Connect the air supply and press Figure 3 (6).
● Adjust Figure 3 (11/13) to give required
advance, retract feeds for the operator.
● Use Figure 5 (1) for the final depth
adjustment.
● Lock using Figure 5 (9).
● Carry out a set of trial drillings to determine
the ideal advance and HCU settings using
Figure 3 (11).
SETTING TAPPING OPERATION
Note 1: lt is important that the advance
rate of the tool is set to match the pitch
of the thread which is to be tapped.
An incorrect advance rate will result in
a deformed thread, this will be more
noticeable in plastics or light alloy
materials.
Note 2: The retract rate should be set to
withdraw the tap at a slightly faster rate
than it advanced, this will ensure a clean
withdrawal.
● Mount a tool, with the selected tap securely
retained in the chuck, above a test block to
carry out sample tapping operations.
● The end of the tap MUST be at least 14mm
(9/16in) above the test block, to allow for the
tapping head reversing engagement travel.
● Set the gap between Figure 5 (2) and (1) to
equal the tapping depth PLUS the distance
the tap is above the work piece.
● Adjust Figure 3 (11/13) to give the required
advance, retract feeds for the operation.
● Carry out a trial tapping operation and inspect
the finished thread form, adjust as necessary
Figure 3 (11/13) and repeat until information in
NOTES 1 and 2 are satisfied.

Cleaning
Requirements:
(1) Container to immerse components.
(2) Good quality clean paraffin.
● Soak the components in the container
containing the paraffin.
● Ensure full immersion, agitate components to
ensure that air passages are flushed through.
● Remove components from the container,
thoroughly dry and blow through air passages
to remove moisture.
● Place components in an air tight container
until required for assembly.
● Dispose of the dirty paraffin in accordance
with health and safety regulations.

● Dismantle the tool using the exploded view.
● Clean all components and inspect for wear or
damage, exchange if necessary.
● Apply new lubricant to the relevant parts in
accordance with list.
