TROUBLESHOOTING

•

SAW WON’T REACH FULL RPM

– Air filter or pre filter may be dirty.

•

SLOW CHAIN SPEED

– Chain tension too tight. Chain should always be able to be pulled

around the bar by hand. It is normal for the chain drive links to hang below the bar.

•

POOR CUTTING SPEED

– Diamonds may be “glazed over”. Make a few cuts in an abrasive

material such as a cinder block to expose the diamonds.

• PREMATURE CHAIN STRETCH – Not enough water pressure. The minimum water pressure

required is 20 psi (1.5 bar).

Insufficient water supply may result in excessive wear to the

diamond chain, which can lead to loss of strength and diamond chain breakage.

•

CHAIN TENSIONER BREAKAGE

– Side cover nuts are not tight enough.

Torque to 20 ft-lbs (27Nm).

•

WATER NOT FLOWING

– Water hose is kinked or supply is not turned on.

•

WON’T START

– Turn ignition switch on or possible defective spark plug.

•

WON’T START

– Low compression, less than 120 psi (8 bar). Possible incorrect fuel mixture.

Reference: new = 150 to 180 psi (10 to 12 bar)

used = 140 to 160 psi (9 to 11 bar)

•

DIFFICULT TO START

– Possible flooded engine. Turn ignition switch on, push choke in, hold

throttle on full with foot and pull starter cord until engine starts.

•

DIFFICULT TO START

– Possible fouled spark plug. Remove spark plug, clean with wire brush

and re-gap.

•

CHAIN BREAKAGE

– Chain installed backwards. Bumpers should lead segments into the cut.

•

CHAIN BREAKAGE

– Not enough feed pressure while cutting. Avoid letting the saw bounce

and chatter.
