Before Use
Fitting the quick connector
Note: This tool is supplied with two different male airline quick connectors:
EQ-4 – commonly used in Europe
EN-6 – mainly used in the UK
EQ-4
Europe
• Please choose the connector that is compatible with the airline system you are
using, and install as outlined below:
1. Apply some PTFE tape (not included) to the screw threads of the Quick
Connector (5). This will help to maintain an air tight seal
Note: Apply PTFE tape tightly and in a clockwise direction, so it does not come off
when the thread is screwed into the tool.
2. Remove the protective plug from the air inlet
3. Using a spanner (not included) screw the quick connector into the air inlet
located at the base of the handle
4. Connect to airline, pressurise carefully and carry out a leak check (e.g. by
spraying small amounts of soapy water on to the outside of the connectors)
• Air lines fitted with matching female quick connectors will now be a push fit
to the tool

LEADER HOSE
1. This tool should be connected to a clean, dry air supply with inline oiler and
water separator
2. Do not allow supply pressure to exceed the maximum stated (see
"Specifications")
3. Ensure that water is drained from air system daily
4. Ensure that all parts of the system (hoses, couplers, etc.) are correctly rated
for the air pressure to be used
Setting tool power
• The tool speed/power can be adjusted by reducing/increasing the air supply
pressure within the range specified in 'Specifications'
Operation
WARNING: Ensure the material to be cut does not exceed the cutting capacity (see
'Specifications') of this air nibbler.
1. Mark the line or shape to be cut on the material
2. Grip the tool firmly and depress the Throttle Lever (1) to begin cutting
3. Apply light pressure to move the air nibbler through the material
4. If the air nibbler stalls whilst cutting, release pressure on the throttle lever to
turn off the tool. Remove the tool a few centimetres from the cutting edge.
Depress the throttle lever to restart the cutting process
Note: This air nibbler is designed for cutting gradual curves, not 90° corners.
When you have finished cutting:
5. Release pressure on the throttle lever
6. Disconnect the air nibbler from the air supply
Note: DO NOT allow the tool to run in 'idle rotation' for an extended period of time.
This will shorten its life.
WARNING: Be aware that air tools may hold residual pressure after use. Always
bleed air pressure from the tool after shutting off air supply.
