Troubleshooting

TROUBLESHOOTING

PROBLEM

Possible Cause

POWER CUTTER WON'T REACH 

FULL RPM

Low hydraulic oil.

Worn hydraulic power cutter motor

Worn hydraulic valve assembly.

Worn powerpack pump

SLOW CHAIN SPEED

All of the above, plus chain tension too tight. Chain should always be 

able to be pulled around the guidebar by hand. It is normal for the drive 

links of the chain to hang below the guidebar. See pages 15-19 for chain 

tensioning instructions.

POOR CUTTING SPEED

All of the above, plus diamonds may be glazed over. Make a few cuts in an 

abrasive material to expose the diamonds.

Chain or diamonds may be worn out.

Worn drive sprocket.

PREMATURE CHAIN STRETCH

Initial chain tension too tight.

Bar nose buried in cut.

Not enough water pressure. The minimum water pressure required is 1.5 

bar (20 psi). 

Chain comes in contact with ground, dirt, gravel and/or sand.

CHAIN TENSIONER BREAKAGE

Side cover nuts are not tight enough. Torque to 27-33 Nm (20 -25 ft-lbs).

Tensioning with side cover nuts already tight.

Tensioner pin not aligned and side cover tightened.

WATER NOT FLOWING

Water hose is kinked or water supply not turned on.

Water ports plugged with debris.

Damaged or worn water valve in power cutter.

MOTOR DOES NOT TURN

Hydraulic lines connected backwards or power pack is set to reverse. 

Chain tension is too tight.

CHAIN BREAKAGE

Improper chain tension.

Insufficient water pressure.

Inserting power cutter into slot narrower than diamond chain segments.

Using chain that is already stretched beyond ability to tension.

Contact with exposed rebar or steel.
