LUBRICATION AND SERVICE
• Check oil levels, wiring, hoses (air, fuel, water) and lubricate machine daily.
• Repair or replace all worn or damaged components immediately.
• Check drive belt tension, do not over-tension.
• Make sure machine has full set of matched belts.
• Check blade shaft, make sure arbor and threads are not worn, damaged, or bent.
• Blade shaft bearings should be tight, no free play side-to-side or up and down.
• Grease blade shaft bearings daily.
• Blade collars should be clean, free of nicks and burrs. No diameter wear and not out of round.
• Drive pin not excessively worn or bent and free of gouges.
• All guards in place and secure.
• All fasteners tight and secure.
• Air filter / oil filter (hydraulic or engine) clean.
• Flush clean water through the pump and spray the assembly every night. This prolongs the pump and blade life.
• Clean machine before starting lubrication maintenance.
• Insure machine is on solid, level ground before starting maintenance.
• During lubrication maintenance insure strict cleanliness is observed at all times.
• To avoid the risk of accidents, use the correct tool for the job and keep tools clean.
• The draining of engine oil is best carried out when the oil is warm not hot.
• Any spilled oil must be cleaned up immediately.
• Use only clean containers for oil and only clean, fresh oils and grease of correct grade.
• Contaminated Water / Fluids / Oil / Filters Must Be Disposed of Safely.

CAUSE
• Blade is on a damaged or worn saw.
• Worn collar.
• Blade runs at an incorrect speed.
• Collar / flange diameters are not identical.
• Blade is bent as a result of dropping or twisting.
• Blade is too hard for material being cut.
• Blade has become dull.
• Blade does not cut material it was specified for.
• Abrasive wearing of the core faster than the
segments.
• Collars / flanges are not properly tightened,
permitting blade to rotate or vibrate on the
shaft.
• Collars / flanges are worn or dirty.
• Blade is not properly mounted.
• Shaft bearing are worn.
• Surges occur because engine is not properly
tuned.
• Blade arbor hole is damaged from incorrectly
mounting the blade.
• Bond / matrix is too hard for material.
• Blade is slipping, wearing one half of blade
more than other.
• Check for bad bearings, bent shaft, or worn
mounting arbor.

REMEDY
• Check collars / flanges to make sure they are
clean, flat and of correct diameter.
• Set engine at proper RPM.
• Use proper size blade collars / flanges.
• Do not use bent blade. Contact blade
manufacturer.
• Select proper blade for material being cut.
• Sharpen by cutting on softer abrasive material
to expose diamonds. If continually sharpening,
the blade is too hard for the material being cut.
• Break – in on the material to be cut. Sharpen as
you would a dull blade.
• Use water to flush out fines generated during
cutting.
• Use wear- resistant cores.
• Make certain the blade is mounted on the
proper shaft diameter. Tighter the shaft nut
with a wrench to make certain that the blade
is secure.
• Clean collars / flanges, make sure they are not
worn. Tighten arbor nut.
• Make sure the pin bole slides over drive pin.
• Install new blade shaft bearing or blade shaft,
as required.
• Tune engine according to manufacturer's
manual.
• If core is worn or arbor hole damaged, DO NOT
USE. Contact blade manufacturer.
• Replace worn shaft or mounting arbor bushing.
• Make certain that drive pin is functioning.
• Tighten spindle nut.
