Service instructions
Pressure regulators
We recommend using one pressure regulator for each tool. Make sure to
adjust the regulator to the lowest expected pressure on the line. A pressure
regulator will give the following advantages:
• A stable air pressure which results in better accuracy.
• Provides an easy way to adjust the power of the tool.
Air filters and air lubricators
We recommend using air filters and air lubricators, which will give the fol-
lowing advantages:
• Clean air without water and particles resulting in reduced tool wear and re-
duced risk of tool failure.
• Will help to maintain the power and speed of the air motor over time.
Trim-RE or AutoTrim valve?
Use Trim-RE valve:
• For applications where the tool is used to tighten screws with similar joint
rate.
Use AutoTrim valve:
• For applications where the tool is used to tighten both hard and soft joints.
Adjusting the AutoTrim valve
When using a tool with a AutoTrim valve make sure it is correctly adjusted, so
the switching to full power is produced after the rundown and when the pulsing
is starting.
For detailed instructions on how to adjust the AutoTrim valve see section
Settings
Incorrect adjustment of the AutoTrim valve will result in:
• Increased scatter.
• Longer tightening time.
• No shut off.
Service tools
Service tools are designed to make assembly and disassembly fast and easy
with less risk of damaging parts in the process.
Correct tightening of parts is important to:
• Optimize performance of the tool.
• Minimize the risk of parts coming loose during operation.
You can find information about service tools and tightening data in the Spare
part list section of the Product instruction.
Preventive maintenance
Preventive maintenance is recommended once per year or after a maxi-
mum of 250.000 tightening. A complete overhaul include:
• Clean the pulse unit and change worn or damaged parts.
• Clean the air motor and change worn or damaged parts.
