TROUBLESHOOTING
• SLOW CHAIN SPEED - Be sure the compressor is providing the correct air pressure,
90 psi, and cubic feet per minute, 90 cfm. These are the minimum requirements;
ideal performance can be achieved at higher volume.
• POOR CUTTING PERFORMANCE - Diamonds may be “glazed over”. Make a few cuts
in abrasive material such as cinder block to expose diamonds. In the case of the
pipe cutting chain, the segment does not wear away. However, the diamonds will
wear away leaving a smooth surface.
• PREMATURE CHAIN STRETCH - Not enough water pressure. The recommended
water pressure is 20 psi. Do not force the chain. Extra force will cause the chain to
stretch faster.
• CHAIN TENSIONER BREAKAGE - Side cover nuts are not tight enough.
• WATER NOT FLOWING - Water hose is kinked, blockage in guide bar water ports, or
water supply is not turned on.
• MOTOR DOES NOT START -
•
Insufficient air supply. Check compressor and air hose, valves, and air inlet
screen for blockage.
• Chain tension is too tight. Loosen chain tension.
• Iced exhaust. Wait until ice thaws, then lubricate with ice-free air tool oil.
• Vanes sticky. Apply lubricant directly to saw air inlet and blow motor clear. Re-
peat if necessary.
