Possible Cause
Low hydraulic oil.

Worn powerpack pump
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.
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.
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.
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 hose is kinked or water supply not turned on.
Water ports plugged with debris.
Damaged or worn water valve in power cutter.
Hydraulic lines connected backwards or power pack is set to reverse.
Chain tension is too tight.
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.
