Periodic maintenance of your tile saw allows for long
life and trouble-free operation. The saw can gener-
ate considerable quantities of cutting residue. A
cleaning, lubrication, and maintenance schedule
should be maintained.
As a common-sense and preventative maintenance
practice, follow these recommended steps:
• Clean the entire saw, except electrical parts, with
fresh water after each use.
• Pump clean, fresh water for 1 minute through the
water pump and blade-guard assembly to safe-
guard against slurry build-up and clogging.
• Inspect the diamond blade for it is overall integrity.
Check the rim for wear or damage.
• Use a soft cloth to clean the water and dust on the
machine.
• Ventilation openings and switch levers must be
kept clean and free of foreign matter. Do not at-
tempt to clean by inserting pointed objects through
openings.
Never use water or any other
CAUTION
chemical liquids for cleaning the
electrical parts of the machine.
