Other Maintenance - Husqvarna 750 Operator's Manual

Guards
Check all guards for damage and proper function daily espe-
cially the blade block. Blade block and cover should be secure
to the saw and not damaged. Lexan side covers on the blade
block should move freely up and down.
Diamond blade
Inspect diamond blades daily for damage, cracks, secure fit
to the arbor, loss of segments, warping or overheating. If any
blade shows any of these problems, discard the blade and
never use.
Skid plate
Inspect the skid plate daily for damage, excessive wear in the
blade slot, burrs on the concrete surface side, twisting and free
movement up and down when installed on the blade block.
Replace the skid plate with each new diamond blade. Never
reuse the skid plates or spalling and raveling may result.
Saw controls
Inspect all controls for proper function daily. Check all the
interlocks for operation especially the red engine on/off
switch for proper operation.
Belts
Inspect the blade drive belt and transmission belt for cracks or
signs of wear. The belt tension is controlled by belt tensioner
and does not require adjustment. Inspect the belt tensioners
for free movement up and down. Insure the belt tensioners
bearings roll freely.
Blade shaft bearings
Lubricate the blade shaft bearings with 3 pumps of Lithium 12
based grease every 50 hours.

OTHER MAINTENANCE
