Daily maintenance procedure
A properly maintained machine reduces air consumption and extends the life of the unit.
Prerequisites: Air supply : 75 to 85 psi (5.5 bar) – Electrical : 110-120 vac.
Daily lubricate the high speed handpieces on the second larger holes and operate the handpiece for 10 seconds.
Step 2 and 2.2
The low speed handpiece can be broken down into three parts. Disassemble the three parts, lubricate the second larger holes (Fig.1), lubricate both ends of the contra-angle, and finally lubricate the prophy-angle. Once this is done, re-assemble and operate the handpiece for 10 seconds, then wipe clean the excess oil on the exterior of the handpiece.
Unplug your compressor at the end of the day and drain all pressure by loosening screw* below air reservoir. This will also eliminate condensation and prolong the life of the reservoir. DON’T FORGET TO tighten the screw before starting your day!
*Don’t unscrew completely to prevent the parts from falling.
Empty the humidity filter by opening the drain at the bottom. Use a cloth to avoid getting wet.
Empty the oil filter by pushing the valve at the bottom. Use a cloth to avoid getting wet.
Listen for unusual compressor start-ups. If the compressor starts occasionally when not being used, it is a sign that there is a leak in the system. If this situation is frequent, contact the manufacturer for assistance.
Weekly maintenance procedure
Verify the oil level in the compressor. If the oil level is less than half, slowly fill the reservoir by pouring a small quantity of oil at a time. Wait 5 minutes and check the level. Do not fill more than half. Use only compressor oil to fill.
Verify the pressure of the handpieces (with the exception of the Piezo) and adjust, if necessary. Manufacturer’s guidelines can vary, but the pressure should be set between 35 and 45 lbs. Screws under the dental machine allow you to change the pressure on individual handpieces.
An annual preventive maintenance is recommended. The maintenance consists of replacing all filter elements, changing the oil in the compressor, checking for leaks, resetting pressures, and completing performance analysis. Contact your Highdent™ supplier for further details.
