MAINTENANCE
- 17 -
Have your electrician check the voltage at the motor
when the saw is cutting.
All Stone single phase masonry motors are equipped
with manual reset overload. When the overload
trips, turn the switch to the OFF position, allow the
motor to cool for 5 to 10 minutes, then push the reset
button. A click indicates reset.
CLEANING
At the end of each day’s use, clean the sludge from
the saw. Flush water through the pump and water
hoses every night.
BEFORE STORING
Before the saw is stored in the warehouse to wait for
the next job, use a wire brush to remove hard, caked
sludge. Clean and thoroughly lubricate moving parts
so when the saw is taken to the next job it is ready to
operate at top efficiency.
Check the extension wire size per chart in the
Technical Data section of this manual. Undersized
wires will burn out expensive motor. Use 230 volts
wherever possible.
If you have motor problems, contact your dealer (or
Stone directly in an emergency) for the name of your
nearest Authorized Service Dealer. If the motor is
under warranty, sending it to a Non-Authorized
Service Dealer voids the warranty.
DAILY
Keep the drive belt tight! Do not operate on low
voltage! Full voltage is essential to economical
operation. Always use 230 volts where available,
with a heavy duty extension cord. Have an electri-
cian check the incoming voltage at the saw motor.
Drive belts must be tight! Power goes from the
motor to the arbor shaft—when belts are loose,
power is lost. Replace worn belts without delay.
Replace belts in sets only.
The blade must fit the arbor snugly, especially
diamond blades, otherwise pounding will occur,
seriously damaging the blades. If the arbor shoulder
is grooved where the diamond blade has bound in
the cut while the shaft has continued to turn, the
arbor must be replaced or the blade life will be
severely shortened.
The blade flanges must be full diameter—minimum
4”. Replace worn down flanges at once as under-
sized flanges shorten blade life and cause breakage.
Flanges should be clean and free of nicks and burrs.
Check the conveyor cart condition regularly.
Replace wheels and wood inserts frequently.
Be certain the cutting head is correctly aligned.
Misalignment through handling damage or transport-
ing the saw with the cutting head on the frame can
seriously affect blade life. Check blade mounted,
with square against cutting table, vertical and
horizontal.
Replace noisy bearings at once! Worn bearings will
very quickly destroy the blade.
Flush clean water through the pump and spray the
assembly every night. This prolongs the pump and
blade life.
Blade shaft bearing should be tight--no free play
side-to-side or up-and-down.
Check oil levels, wiring, hoses, air filters, wheels
and lubricate machine daily.
All guards in place and secure. All fasteners tight
and secure.
Check pulley alignment using straight edge. All
pulleys have (2) set screws and require thread
locking loctite.
The slurry that accumulates in the bottom of the
water reservoir pan is as abrasive as a cutting
compound, and , if it accumulates heavily, will
shorten the life of the water pump and of the blades.
