Troubleshooting
PROBLEM
Possible Cause
Solution
SLOW CHAIN
SPEED
Chain tension is too tight.
Tension chain to factory recommendation. See
chain tensioning instructions section.
POOR CUTTING
SPEED
Chain tension is too tight.
Check chain tension, see above.
Diamonds may be glazed over.
Make a few cuts in abrasive material to expose
diamonds.
Chain or diamonds may be worn out.
Replace chain.
Worn drive sprocket.
Replace drive sprocket.
PREMATURE
CHAIN STRETCH
Initial chain tension too tight.
Tension chain to factory recommendation.
Bar nose buried in cut.
Avoid nose buried cuts by using the step cut
method.
Not enough water pressure.
The minimum water pressure required is 1.4 bar
(20 psi).
Chain comes in contact with ground,
dirt, gravel and/or sand.
Avoid dirt, sand and gravel by excavating and
clearing
the surrounding area.
CHAIN
TENSIONER
BREAKAGE
Bar clamp bolts are not tight enough.
Torque to 27-33 Nm (20 -25 ft-lbs).
Tensioning with bar clamp bolts
already tight.
Loosen bar clamp bolts prior to tensioning
adjustment
Tensioner pin not aligned and bar
clamp bolts tightened.
Ensure tensioner pin is through the bar pin hole
WATER NOT
FLOWING
Water hose is kinked or water supply
not on.
Ensure water line is not twisted and valve is
turned on
Water delivery system plugged or not
functioning properly.
Ensure proper flow of clean water to the power
cutter.
Guidebar water ports are plugged
with debris or ice.
Using a pipe cleaner or small wire, push debris back
into the water channel and blow compressed air
into guidebar exit port(s).
Damaged or worn water valve on
water supply line.
Replace water valve.
MOTOR DOES

Ensure plugged into the proper outlet (220 - 240V,
60Hz supply).
GFCI/PRCD is not reset.
Reset GFCI/PRCD. With the power cutter unplugged,
inspect the power cable for damage or wear.
Power source voltage is too high or
too low.
Check supply voltage and adjust if capable.
Measure voltage with multimeter on ACV mode.
Internal damage to motor or
electronics.
Return to service center for repair.
CHAIN BREAKAGE
Improper chain tension.
Tension new chain to factory recommendation. See
chain tensioning instructions section.
Excessive drive sprocket wear.
Replace drive sprocket.
Insufficient water pressure.
Check water valve and water delivery system for
proper water flow (20 psi/1.4 bar).
Inserting into slot narrower than
diamond chain segments.
Do not cut in a slot narrower than the chain including
pre-existing cracks.
Using chain that is already stretched
beyond ability to tension.
Replace chain.
Contact with exposed rebar or steel.
Replace chain.
