-REMOVE ALL ADJUSTING KEYS AND WRECHES: From habit of checking to see that all keys and adjusting wrenches are removed from tool before switchine in "ON".

-ALWAYS USE SAW BLADE GUARD AND RIVING KNIFE for every operation for which they can be used, including through sawing. Through sawing operations are those when the blade cuts completely through the work piece as in ripping or cross cutting.

-ALWAYS HOLD WORK FIRMLY AGAINST RIP FENCE OR MITRE FENCE.

-USE PUSH-STICK if distance between blade and rip fence is less than 120 mm/5".

-NEVER PERFORM ANY OPERATION "FREE-HAND".

-NEVER REACH BEHIND, OVER OR UNDER THE CUTTING TOOL WITH EITHER HAND FOR ANY REASON. Keep hands away from saw blade; do not reach into area 120 mm left and right of saw blade.

-DIRECTION OF FEED: Feed work into saw blade against direction of rotation only.

-AVOID KICKBACKS (work thrown back at you) by keeping the rip fence parallel to the blade, keeping riving knife and guards in place and operating, by not releasing work before it is pushed all the way past the saw blade, and by not ripping stock that is twisted or warped or does not have a straight edge to guide along the fence.

12.1Problems

-If saw blade is stalled by waste, or the discharge port of the chip case clogged, switch machine off and let blade come to a complete standstill before attempting to remove obstruction.

-Switch motor off immediately if blade has stalled. A dull blade is most often the cause for what appears to be a loss of power of the motor.

-An extremely dull blade leaves burn marks in the kerf. Replace or resharpen at once.

-After a power failure the machine has to be switched on again.

13Care and Maintenance

-Always disconnect from power before servicing. Do not rely on switch alone.

-This machine requires very little maintenance.

-When changing the saw blade apply a light coat of oil to the arbor bolt.

-Regularly apply a light coat of oil to the mitre fence guide rod.

13.1 Tool maintenance

Residue resin built-up on the saw blade(s) should be removed regularly. Immerse blade in a natrium carbonate solution or in paraffin/kerosene or mineral turpentine for 24 hours. The residue resin is then easily wiped off with a rag.

Clean and sharp saw blades improve the quality of the cuts and cutting efficiency.
