Belt tension and changing (fig, 18)
WARNING:
Always disconnect the machine from its power supply before starting any main-
tenance work.
Turn the main switch on “off” and lock if necessary with a padlock.
After removing the side panel on the machine the belts can be tensionned simply by unlocking
the bolt (1), and pushing the motor down, and then locking again the bolt (1).
Use only original belts Type SPZ 850.
Make sure the belts are not overtensionned, because this will lead to damage of the bearings on
the saw arbor, and belts.
To check the tension of the belts, push in the midlle between the two pulleys with an average
pressure of 3 kgs. If the belt bends 5 to 6 mm, it has the right tension. This can be checked
manually, and on a regular basis.
Maintenance of the machine
The interior and exterior of the machine have to be cleaned regulary to avoid any accumulation
of dust and woodchips.
Any deposition of resin on the sliding table and other surfaces has to be removed.
Never smoke while cleaning the machine, and especially when using petrol or kerosine, or
other inflammable products. This to avoid explosion, and serious burns as a result to the opera-
tor.
All moving parts have to be kept clean and have to be lubricated with a thin penetrating oil.
All bearings are double sealed and need no lubrication. The use of a dust extraction system will
most certainly extend the life of your machine.
The lifetime of the motor can be extended by blowing out sawdust and chippings from the cool-
ing fan and motor itself.
Problems and troubleshooting
1. The machine does not start when the start button is activated :
- workshop main fuse is switched off: power cut, power shortage, or general overload.
- “Star-Delta” switch in the wrong position: put switch on “Star”.
- main switch off: put switch on “1”.
2. Reduction of cutting speed when working :
- belt tension not correct: tension the belt
- motor overload due to incorrect feed rate: reduce the feed rate
- blunt tools: sharpen tools
3. Vibration of the sawblade or arbor :
- unbalanced tool: replace or have the tool balanced
- worn or damaged belt: replace the belt
- overtensionned belt: loosen belt
4. Thermal overload does not re-arm automatically after shut-off and cooling
down period :
- overload is not set on automatic reset, or the overload is faulty: set on automatic, or replace
