9. Troubleshooting
Hydraulic unit or saw system overheats / lacks power
Problem
Possible cause
Action to be taken
Saw system overheats:
– Water supply inadequate,
– Water flow rate at least 7 l/min.
→
Too hot to touch
water too warm
– Increase water flow rate >7 ltr./min.
→
Steam rises from
– The water should be cool
saw head
(tap water < 20° C)
→
Drop in sawing
– Saw blade not cutting,
– Water supply hose must be connected
performance
segments are polished
to lower nipple on the hydraulic unit.
– Sharpen the saw blade
→
Use a sharpening plate
→
Alternatively, make a cut in abbrasive
brick or concrete with very little water.

– Cam-action rollers too tight
– Adjust cam-action rollers: Set
saw system
levers to correct tension without play.
→
Overheats
– Cam-action rollers too lose
– Mount the rails securely.
→
Sawing performance
– Play at saw head causes blade
See page 29.
drops
to wander
– Do not overload the saw blade.
→
Saw blade wanders
– Saw blade overloaded, too soft,
Saw at a reasonable cutting depth.
off course
blade takes on blue color
– When cutting at great depth
– Signs of friction / scoring on
≥
60 cm (blade diameters 1500 /
sides of blade
1600 mm), make guide cut using
– Cutting too deep
800 mm dia. blade with 5 mm
wide segments.
– Select the correct saw blade
specification (for high power).
– Saw blade motor speed too
– Run at recommended speed or
high
oil flow rate (see table on page 39).
– Very high steel reinforcement
– Reduce load (advance) slightly
content, very hard concrete or
from time to time or allow blade
hard aggregates
to cool by running at low speed
without load for 2-3 minutes.
– Unsuitable saw blade
– See page 15 of operating instructions
for recommended saw blades
Operator
– Saw blade running at too high
– Observe recommended oil flow rate
speed
= Observe recommended r.p.m.
