Shutdown - LEMAN SRM170 Manual De Instrucciones

WARNING!
After use always make sure that the electric power supply has been disconnected.

6.15 SHUTDOWN

If the machine is to be shut down for a prolonged period of time, the parts subject to wear must be lubricated and
the machine covered with a plastic sheet and stored in a sheltered, dry place. If these instructions are observed
when work with the saw is resumed the machine will be in perfect working order.
7. MAINTENANCE
WARNING!
It is essential for all maintenance operations to be performed with the motor off and the machine
unplugged from the power supply.
Apart from the oil change in gear-motor, the machine does not require any particular maintenance operations. It is
however important to remember the following:
- Clean the machine and the work area regularly.
- Use saw blades with teeth that are suitable for the materials to be cut; this ensures optimum cutting results. Your
saw blade supplier can provide you with helpful advice.
- Replace the saw blade when it is worn, in order to avoid vibrations and inaccurate cuts.
- Clean the coolant tank when necessary or at least twice a year, through the special opening on the tank itself.
- Check the cooling pump regularly.
- Ensure that the safety guard completely covers the blade.
WARNING!
FOR ANY PROBLEMS OTHER THAN THOSE DESCRIBED ABOVE CONTACT THE MANUFACTURER
IMMEDIATELY.
8. TROUBLE SHOOTING
SYMPTOM POSSIBLE CAUSE (S)
1. Incorrect blade tension
