EQ-4 – commonly used in Europe
EN-6 – mainly used in the UK
- Please choose the connector that is compatible with the airline system you are using, and install as outlined below:
- Apply some PTFE tape (not included) to the screw threads of the Quick Connector. This will help to maintain an airtight 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. -
Remove the protective plug from the air inlet
-
Using a spanner (not included) screw the Quick Connector into the air inlet located at the base of the handle
- 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
⚠ WARNING: Do not attach the tool to a hose and the hose to a compressor with only threaded connections. Always use Quick Connectors so the tool can be removed from the air supply connection when needed for safe operation.
⚠ WARNING: Never fit a female Quick Connector directly to the leader hose/whip hose or directly to the tool. The stored pressurised air in the tool, even when detached from the main air supply, can operate the tool unexpectedly.
Recommended air supply
- This tool should be connected to a clean, dry air supply with inline oiler and water separator
- Do not allow supply pressure to exceed the maximum stated (see 'Specification')
- Ensure that water is drained from air system daily
- 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 can be adjusted by pressing and turning the Air/Torque Control Dial (4):
'1' = minimum, '4' = maximum
Forward and reverse
- This tool features a forward/reverse function. Select the desired direction by pushing the Forward/Reverse Switch (2). The letters 'F' and 'R' marked on the tool indicate the switch position for forward and reverse.
