WARNING
Risk of injury due to oil escaping under high pressure! Oil escaping under high pressure can injure the
skin and the eyes.

cutting operations to heat up the cutting tool.

against the material to be cut.
Always make sure that the material to be cut is fully inserted into the cutting head.
Do not exceed the maximum cutting capacity.
Do not attempt to cut material that cannot be inserted fully into the cutting head.
3. Press and hold down the control switch until the piston retracts.
