Changing the Saw Blade
Maintenance
36
Tighten up the saw nut, using the tommy bar
to hold the shaft steady. Check the riving knife
is aligned with the saw blade, and correctly
positioned. Replace the table insert and secure
with the 5 screws. Replace the saw blade guard.
When everything is satisfactory, turn the saw blade
once by hand to check it doesn’t foul anywhere.
Reconnect the machine to the mains supply.
Give the machine a ‘quick’ burst check ( i.e. quick
ON-OFF) to ensure everything is O.K. If everything is
satisfactory, continue to use the machine. Check the
old blade for sharpness, missing teeth, resin buildup,
etc., clean if necessary and send for refurbishment/
resharpening if required. If the blade is not to be
re-sharpened, clean and pack away in its stowage
case.
Keep the saw as clean and free from saw dust build
up as is practical. Periodically, remove the saw gullet
and vacuum out and clean out the saw box and the
extraction housing. Remove any resin build up in the
saw box, using a proprietary resin cleaner.
Remove the upper side panels and clean the
threaded drive shafts of the rise and fall and tilt
mechanisms. At the same time check the belt
drive, i.e. the belt is not ‘glazing’ with resin build
up, likewise with the pulley wheels. Check the belt
tension. If the belt
(A)
is becoming slack, loosen
the motor hold down bolts
(B)
and drive the motor
backward with its adjusting bolt
(C)
. (See figs 116-
117) Check the saw blade regularly for chipped,
missing, damaged teeth etc. and remove any resin
build up from the blade, riving knife etc.
If you have finished using the saw bench, clean
above and below the work table and using a damp
cloth wipe the saw bench over. If the saw bench
is not going to be used for a period of time, use a
rustproofing spray (see our catalogue), spray a light
coat over the work table and place a dust sheet over
the saw bench.
